THE STUDY OF PHILIPINE’S CULTURE

Introduction
The visitor to Metro Manila commonly sees the Philippines as the most westernized of Asian countries and in many ways, it is. But there is also a rich underlay of Malay culture beneath the patina of Spanish and American heritage. National cultural life is a happy marriage of many influences, as the indigenous Malay culture is assimilated and adapted to different strains in a practice typical of Malay temperament. An upsurge of Philippine nationalism stimulated a desire to preserve the ancient heritage without restricting its openness to foreign artistic influence.
The Philippines is an archipelago of 7,107 islands. It stretches from the south of China to the northern tip of Borneo. The country has over a hundred ethnic groups and a mixture of foreign influences which have molded a unique Filipino culture.

Before the Spanish explorers came, Indo-Malays and Chinese merchants had settled here. In 1521, the Spaniards, led by Ferdinand Magellan, discovered the islands. The Spanish conquistadores established a colonial government in Cebu in 1565. They transferred the seat of government to Manila in 1571 and proceeded to colonize the country. The Filipinos resisted and waged Asia's first nationalist revolution in 1896. On June 12, 1898, Emilio Aguinaldo declared the Philippines independent from Spain and proclaimed himself president. After ruling for 333 years, the Spaniards finally left in 1898 and were replaced by the Americans who stayed for 48 years. On July 4, 1946, the Americans recognized Philippine independence.

The Philippines is the third largest English-speaking country in the world. The country is divided into three geographical areas: Luzon, Visayas, and Mindanao. It has 17 regions, 80 provinces, 122 cities, 1,512 municipalities, and 42,025 barangays
Ethnic Make-up: 
Christian Malay 91.5%, Muslim Malay 4%, Chinese 1.5%, other 3% 
Religions: 
Roman Catholic 83%, Protestant 9%, Muslim 5%, Buddhist and other 3%

Culture of Philippine
The Filipinos does not come out into the world just as they are now today. The Philippine is not a pure cultured country and neither the Filipinos’ blood that runs within their veins pure – for just like the intermarriage of different cultures into the fabric of Philippines culture so also the Filipino is a product of the marriage of different races who conquer the archipelago- nor their dominant beliefs and traditions today is a pure culture of their own.
Mixed culture
Philippine culture is a mixed conglomeration of different culture taken from and influenced by those who conquest it since the beginning of its arousal from the beds of the Pacific Ocean.
Historically, it was said that the first inhabitants who settled on the Philippine archipelago are the Negritos and their fellow Australoid Sakai race who migrated from the South Asia during the Pleistocene Era who cross the soil bridge toward the Philippine archipelago whose culture become the first Philippine culture ever recorded in the Philippine history. However, their cultures have not become the dominant culture of Filipinos today but somehow have some traces of it like fishing. But the most influential race that migrated into the Philippine archipelago that marks a great impact on the Philippine culture today and that shape the Filipinos today are the Malay race.
The Malay race (Modern day culture)
The Malay race are said to be the second group who inhabited the country who come from Taiwan or Formosa then. They are called Austronesian or Malayo-Polynesian people. They have a more advance culture than the Negritos. For they are highly civilized race that has brought and shape the Philippine literature, Philippine art, and the Philippine government today altered only by the culture of the Spaniards and American conquerors who conquest the Philippines whom these conquerors have injected and intermixed on it. Thus, this conglomerated culture has now become the modern day culture of the Filipinos today. One of the culture that mostly influence the Filipino today from both Malay, Spaniards and Americans, that affects predominantly the Philippine literature and Philippine art is Malay’s native and Islam beliefs and the Spaniards and Americans Roman Catholicism beliefs or the catholic Christianity. For most of the writings of the Filipino writers and authors today, have either a reflection or vestiges of their Islam and Malay philosophy or catholic Christian beliefs, as well as the art of their wrings and the designs of their books.
Languages in the Philippines

Filipino (formerly Pilipino) is based on Tagalog and is the official language of the Philippines.  In spite of being the national language, only about 55 percent of Filipinos speak the language. In addition to Filipino are about 111 distinct indigenous languages and dialects, of which only about 10 are important regionally. 
English is generally used for educational, governmental and commercial purposes and is widely understood since it is the medium of instruction in schools.  The Philippines are the third largest group of English speaking people in the world, after the United States and the United Kingdom.

Since English is widely spoken in the Philippines, it is common to hear Filipinos use a mixture English and Filipino words or phrases, known as "Taglish" (a mixture of English and Tagalog), in their everyday conversations. A steadily dwindling minority still speak Spanish, which had at one time been an official language. 
Filipino Society & Culture
Filipino Family Values
The family is the centre of the social structure and includes the nuclear family, aunts, uncles, grandparents, cousins and honorary relations such as godparents, sponsors, and close family friends. People get strength and stability from their family. As such, many children have several godparents. Concern for the extended family is seen in the patronage provided to family members when they seek employment. It is common for members of the same family to work for the same company. In fact, many collective bargaining agreements state that preferential hiring will be given to family members.
Filipino Concept of Shame
Hiya is shame and is a motivating factor behind behavior. It is a sense of social propriety and conforming to societal norms of behavior. Filipinos believe they must live up to the accepted standards of behavior and if they fail to do so they bring shame not only upon themselves, but also upon their family. One indication of this might be a willingness to spend more than they can afford on a party rather than be shamed by their economic circumstances. If someone is publicly embarrassed, criticized, or does not live up to expectations, they feel shame and lose self-esteem.
Meeting Etiquette
  • Initial greetings are formal and follow a set protocol of greeting the eldest or most important person first.
  • A handshake, with a welcoming smile, is the standard greeting.
Gift Giving Etiquette
  • If you are invited to a Filipino home for dinner bring sweets or flowers to the hosts.
  • If you give flowers, avoid chrysanthemums and white lilies.
  • You may send a fruit basket after the event as a thank you but not before or at the event, as it could be interpreted as meaning you do not think that the host will provide sufficient hospitality.
Dining Etiquette
  • It is best to arrive 15 to 30 minutes later than invited for a large party.
  • Never refer to your host's wife as the hostess. This has a different meaning in the Philippines.
  • Dress well. Appearances matter and you will be judged on how you dress.
  • Compliment the hostess on the house.
  • Send a handwritten thank you note to the hosts in the week following the dinner or party. It shows you have class.
Table manners
  • Wait to be asked several times before moving into the dining room or helping yourself to food.
  • Wait to be told where to sit. There may be a seating plan.
  • Do not start eating until the host invites you to do so.
  • Meals are often served family- style or are buffets where you serve yourself.
  • A fork and spoon are the typical eating utensils.
  • Hold the fork in the left hand and use it to guide food to the spoon in your right hand.
  • Whether you should leave some food on your plate or finish everything is a matter of personal preference rather than culture-driven.
Conclusion

The transformation of local cultures in the Philippines and the Pacific presents a range of historical and theoretical issues. The lasting impact of Spanish rule in the Philippines was a religious transformation which had a vital impact on local cultures as well as on the growth of national culture over the past fifty years. It was only in Mindanao and in the presence of Islam that limitations occurred on the spatial spread of Catholic influence throughout the archipelago. To a certain extent local social institutions were modified, but in the transformation from Spain to the United States and to nationhood, Philippine culture was maintained both in terms of interpersonal relationships and cultural institutions. The American presence left its legacy in a widespread public education system, which had both positive and negative influences.

Top 10 Insurance Companies By The Metrics - Sea of Knowledge

There are a number of ways to rank the size of insurance companies. Companies can be measured by their market capitalization (the value of the company on a stock exchange) or by using sales figures such as net premiums written in a year or how many policies were sold. (For more, see: Which insurance policies do I really need?)
Largest Public Insurance Companies by Market Capitalization


Non-health Insurance Companies:

Berkshire Hathaway (BRK.A)$308 billion
China Life Insurance (LFC)$80 billion
Allianz (AZSEY)$76.8 billion
American International Group (AIG)$72.3 billion

MetLife (MET)$59.4 billion
AXA (AXA)$57.8 billion
AIA Group Hong Kong (AAIGF)$54.4 billion

Centene Corp. (CNC)$5.7 billion
Health Net, Inc. (HNT)$3.9 billion
WellCare Health Plans (WCG)$3.1 billion
Healthspring (HS)$3.7 billion
Molina Healthcare (MOH)$2.4 billion
(Source: Thompson Reuters)
Not all insurance companies are publicly traded. In fact, many insurers are structured as mutual companies where policy holders of participating policies are essentially partial owners of the company. The mutual company model for an insurance company dates back hundred of years, and there are certain benefits conferred on policyholders that do not exist with publicly traded (stock company) insurers. (For more, see: The Industry Handbook: The Insurance Industry.)
Largest Insurance Companies by Sales and Product Line
It is useful to differentiate between the type of insurance, or line, that is being considered when considering the largest insurance companies. Using sales data is helpful as some of the largest insurance companies in the United States are not publicly traded and therefore their market value is not easily ascertained.
Property & Casualty
Property casualty insurers write policies covering property such as real estate, dwellings, cars and other vehicles. They also write policies dealing with liabilities that may be incurred by accident or negligence related to those properties to defray the cost of lawsuits or medical damages resulting from such incidents.

The top U.S. property casualty companies in 2013 by net premiums written (the amount of money that non-life policies can expect to receive over the life of the contract, less commissions and costs) are:

CompanyNet Premiums Written
State Farm Group$50.8 billion
Allstate Insurance Group (ALL)$24.8 billion
Liberty Mutual$21.5 billion
Berkshire Hathaway (includes GEICO)$21.4 billion
Travelers Group (TRV)$20.6 billion
American International Group (AIG)$19.7 billion
Nationwide Group$14.5 billion
Progressive Insurance Group (PGR)$14.5 billion
Farmers Insurance Group$14.1 billion
USAA Group$10.7 billion
(Source A.M. Best)


Life Insurance Companies
Life Insurance companies promise to pay out a lump sum benefit upon the death of the insured. Although actuarial science has created mortality tables to accurately estimate the future liability of policies to be paid, having financial strength ensures that these companies can meet all of their obligations while still earning a profit.
Life Insurance companies in the U.S. can be ranked by direct premium written (the amount of new policies written directly and not re-insured). For 2013:
CompanyTotal Direct PremiumMarket Share
MetLife (MET)$11.5 billion7.98%
Northwestern Mutual$9.4 billion6.55%
Prudential of America (PRU)$8.4 billion5.79%
New York Life$7.8 billion5.42%
Lincoln National$6.1 billion4.27%
MassMutual$5.1 billion3.52%
John Hancock$4.8 billion3.37%
Aegon (AEG)$4.1 billion2.82%
State Farm$4.0 billion2.79%
Guardian Life Insurance Co.$3.4 billion2.34%
(Source: NAIC)
Health Insurance Companies
Health insurance companies provide policies to cover all or part of policyholder's health and medical costs. Policies may be purchased individually or through an employer. Technically, the United States government is the largest health insurance provider in America through the Medicare program, Social Security and with Medicaid administered by individual states. (For more, see: 5 Things You Need To Know About Obamacare.)
The largest non-government sponsored U.S. health insurance companies measured by total direct premium collected in 2007 was:
CompanyTotal Direct PremiumMarket Share
United Healthcare (UNH)$66.8 billion11.70%
Wellpoint Group (WLP)$55.7 billion9.75%
Kaiser Permanente$43.7 billion7.66%
Humana (HUM)$21.7 billion3.81%
Aetna (AET)$21.7 billion3.81%
Health Care Service Corp$14.9 billion2.60%
American Family$11.6 billion2.04%
Highmark$11.4 billion2.01%
Blue Cross/Blue Shield$9.8 billion1.72%
Cigna (CI)$9.6 billion1.69%
(Source: NAIC. Caveat emptor: The sales data on health insurance companies is from 2007, the last year of available data. The Affordable Care Act (aka 'Obamacare') may have altered these standings.)
The Bottom Line
Ranking the largest insurance companies can be done in a number of ways. Shares of publicly traded companies can be bought to help build a well-diversified investment portfolio that has exposure to the financial and healthcare sectors. Identifying which types of insurance a company primarily deals with helps determine which firms are competitors and which really are not. Looking at sales figures, or premiums collected in a year, one can also see how public companies stack up against privately held or mutual companies which make up a large segment of the industry.

Story of The Lost Wallet - Sea of Knowledge

The Lost  Wallet

It was a freezing day, a few years ago, when I stumbled upon a wallet in the street. There was no identification inside. Just three dollars, and a crumpled letter that looked as if it had been carried around for years.
                                       
The only thing legible on the torn envelope was the return address. I opened the letter and saw that it had been written in 1924 -- almost 60 years ago. I read it carefully, hoping to find some clue to the identity of the wallet's owner.
It was a "Dear John" letter. The writer, in a delicate script, told the recipient, whose name was Michael, that her mother forbade her to see him again. Nevertheless, she would always love him. It was signed Hannah.
It was a beautiful letter. But there was no way, beyond the name Michael, to identify the owner. Perhaps if I called information the operator could find the phone number for the address shown on the envelope.
"Operator, this is an unusual request. I'm trying to find the owner of a wallet I found. Is there any way you could tell me the phone number for an address that was on a letter in the wallet?" The operator gave me her supervisor, who said there was a phone listed at the address, but that she could not give me the number. However, she would call and explain the situation. Then, if the party wanted to talk, she would connect me. I waited a minute and she came back on the line. "I have a woman who will speak with you."
I asked the woman if she knew a Hannah.
"Oh, of course! We bought this house from Hannah's family thirty years ago."
"Would you know where they could be located now?" I asked.
"Hannah had to place her mother in a nursing home years ago. Maybe the home could help you track down the daughter."
The woman gave me the name of the nursing home. I called and found out that Hannah's mother had died. The woman I spoke with gave me an address where she thought Hannah could be reached.I phoned. The woman who answered explained that Hannah herself was now living in a nursing home. She gave me the number. I called and was told, "Yes, Hannah is with us." I asked if I could stop by to see her. It was almost 10 p.m. The director said Hannah might be asleep. "But if you want to take a chance, maybe she's in the day room watching television." The director and a guard greeted me at the door of the nursing home. We went up to the third floor and saw the nurse, who told us that Hannah was indeed watching TV.
We entered the day room. Hannah was a sweet, silver-haired old-timer with a warm smile and friendly eyes. I told her about finding the wallet and showed her the letter. The second she saw it, she took a deep breath. "Young man," she said, "this letter was the last contact I had with Michael." She looked away for a moment, then said pensively, "I loved him very much. But I was only sixteen and my mother felt I was too young. He was so handsome. You know, like Sean Connery, the actor."
We both laughed. The director then left us alone. "Yes, Michael Goldstein was his name. If you find him, tell him I still think of him often. I never did marry," she said, smiling through tears that welled up in her eyes. "I guess no one ever matched up to Michael..."
I thanked Hannah, said good-bye and took the elevator to the first floor. As I stood at the door, the guard asked, "Was the old lady able to help you?"
I told him she had given me a lead. "At least I have a last name. But I probably won't pursue it further for a while." I explained that I had spent almost the whole day trying to find the wallet's owner.While we talked, I pulled out the brown-leather case with its red-lanyard lacing and showed it to the guard. He looked at it closely and said, "Hey, I'd know that anywhere. That's Mr. Goldstein's. He's always losing it. I found it in the hall at least three times."
"Who's Mr. Goldstein?" I asked. "He's one of the old-timers on the eighth floor. That's Mike Goldstein's wallet, for sure. He goes out for a walk quite often."
I thanked the guard and ran back to the director's office to tell him what the guard had said. He accompanied me to the eighth floor. I prayed that Mr. Goldstein would be up.
"I think he's still in the day room," the nurse said. "He likes to read at night...a darling old man."
We went to the only room that had lights on, and there was a man reading a book. The director asked him if he had lost his wallet. Michael Goldstein looked up, felt his back pocket and then said, "Goodness, it is missing."
"This kind gentleman found a wallet. Could it be yours?"
The second he saw it, he smiled with relief. "Yes," he said, "that's it. Must have dropped it this afternoon. I want to give you a reward."
"Oh, no thank you," I said. "But I have to tell you something. I read the letter in the hope of finding out who owned the wallet."
The smile on his face disappeared. "You read that letter?"
"Not only did I read it, I think I know where Hannah is."
He grew pale. "Hannah? You know where she is? How is she? Is she still as pretty as she was?" I hesitated.
"Please tell me!" Michael urged.
"She's fine, and just as pretty as when you knew her."
"Could you tell me where she is? I want to call her tomorrow."
He grabbed my hand and said, "You know something? When that letter came, my life ended. I never married. I guess I've always loved her."
"Michael," I said. "Come with me." The three of us took the elevator to the third floor. We walked toward the day room where Hannah was sitting, still watching TV. The director went over to her.
"Hannah," he said softly. "Do you know this man?" Michael and I stood waiting in the doorway.
She adjusted her glasses, looked for a moment, but didn't say a word.
"Hannah, it's Michael. Michael Goldstein. Do you remember?"
"Michael? Michael? It's you!"
He walked slowly to her side. She stood and they embraced. Then the two of them sat on a couch, held hands and started to talk. The director and I walked out, both of us crying.
"See how the good Lord works," I said philosophically. "If it's meant to be. It will be." Three weeks later, I got a call from the director who asked, "Can you break away on Sunday to attend a wedding?" He didn't wait for an answer. "Yup, Michael and Hannah are going to tie the knot!"
It was a lovely wedding, with all the people at the nursing home joining in the celebration. Hannah wore a beige dress and looked beautiful. Michael wore a dark blue suit and stood tall. The home gave them their own room, and if you ever wanted to see a 76-year-old bride and a 78-year old groom acting like two teenagers, you had to see this couple.
A perfect ending for a love affair that had lasted nearly 60 years.

Explain System Development Life Cycle

Introduction


This approach document is designed for the University of Michigan Information and Technology Services System Development Life Cycle (SDLC) projects. 

A.  Purpose

The intent of Development/Unit Testing is to efficiently and accurately develop, unit test, and provide documentation for Designs produced.  Repeatable, consistent processes and comprehensive documentation support this goal.  The end result should be increased quality (fewer bugs), and the reduction of delivery time and effort needed for subsequent projects.

Computer Information Systems

An information system is a collection of people, hardware, software, data, and procedures that interact to generate information to support users in an organization.

Business Intelligence systems collect data that can be used by a company to help make business decisions.  Two common business intelligence systems are:
  • Data Warehousing: a comprehensive collection of data about a company, its customers, and its business transactions.  This data is put into a form that makes it easy to perform complex queries.  Data warehouses can become very large.  For example Wal-Mart’s data warehouse can hold over 200 terabytes of data.
  • Data mining: intelligent SW used to scan a data warehouse for patterns and relationships within the data that may not be apparent to management.  Another common use of data mining is customer profiling—which attempts to match customers with products they would be likely to purchase.

Explain Features of Strategic Planning

1. They are proactive and non re-active.

2. They are internal in source, and the business venture has absolute control over their application.

3. Strategy can apply once after that it is process of application with no unique element remaining.

4. The outcome is normally a strategic planning which is used guidance to define functional and divisional plan including technology, marketing etc.

5. Strategic planning is the formal consideration of an organization’s future course. All strategic planning deals with al least one of three keys question 

a) What do we do?
b) For whom do we do it?
c) How do we excel?

In business strategic planning the third question is better how can we beat or avoid competition? In many organizations this is viewed as a process for determining where an organization is going over the next year or more- typically 3 to 5 years, although some extended their vision to 20 years.

Definition of Management Information System

Management Information System can be defined as a formal method of collecting timely information in a presentable form. in order to facilitate effective decision making and implementation, in order to carry out organizational operations for the purpose of achieving the organizational goal. A management information system is a system design to provide selected decision –orientation information needed by management plan, control and evaluate the activities of the corporation. It is designed within the frame work that emphasizes profit, planning, performance planning and control at all levels. It complements the ultimate integration of required business information sub system both financial with in the company. 

According to Philip kolter- A marketing information system consist of people, equipment and procedures together,sort,analyse,evaluate and distribute the needed timely and accurate information and marketing decision makers.

Professor Allen S. Lee states that research in the information system field examines more than the technological system,or just the social system or even the two side by side in addition it investigates the phenomena that emerge when the two interact.

An information system can be any organized combination of people, hardware, software, communication network and data resources that collects, transforms and disseminates information in an organization.

Introduction to MIS

            . Introduction

As a consumer, you have instant access to millions of pieces of data. With a few clicks of the mouse button, you can find anything from current stock prices and video clips of current movies. You can get product descriptions, pictures, and prices from thousands of companies across India and around the world. Trying to sell services and products? You can purchase demographic, economic, consumer buying pattern, and market-analysis data. Your firm will have internal financial, marketing, production, and employee data for past years. This tremendous amount of data provides opportunities to managers and consumers who know how to obtain it and analyze it to make better decisions.

System Software

Software is a key component of any information system. Of the total number of corporate dollars spent on computing, the software share is increasing while the hardware share is decreasing. Typically, different sizes of computers use different operating systems, and even the same types of computers may not use the same operating system. The operating system that a computer uses sometimes is called the software platform, or platform. Application software packages often require a specific software platform. A cross-platform application, however, is one that runs on multiple operating systems.

Starting a Computer

When you turn on a computer after it has been powered off, you are performing a cold boot. When you restart a computer that already has been powered on, you are performing a warm boot. Your typically can perform a warm boot by pressing a combination of keys on the keyboard (in Windows, CTRL+ALT+DEL), selecting options from a menu, or pressing a Reset button on the computer.

If you watch the screen closely as the POST is conducted, the value for the total amount of memory can be seen to change as it is measured in the memory test. If the POST results do not match the data on the CMOS chip, an appropriate message should appear. The boot program typically is the first side, first track, and first sector of the hard disk. When you install an operating system, one of the installation steps involves making an emergency disk from which you can start your computer if the hard disk is damaged.

OPERATING SYSTEMS AND UTILITY PROGRAMS

Describe the two types of software

Two types of software are application software and system software.

Application software consists of programs that perform specific tasks for users, such as a word processing program, e-mail program, or Web browser.

System software consists of the programs that control the operations of a computer and its devices. The two types of system software are operating systems and utility programs.

An operating system (OS) is a set of programs containing instructions that coordinate all the activities among computer hardware devices.

A utility program performs a specific task, usually related to managing a computer, its devices, or its programs.

Understand the start-up process for a personal computer

Booting is the process of starting or restarting a computer.

·         When you turn on the computer, the power supply sends an electrical signal to devices located in the system unit.

·         The processor chip resets itself and looks for the ROM chip that contains the BIOS (basic input/output system), which is firmware that holds the startup instructions.

·         The BIOS executes the power-on self test (POST) to make sure hardware is connected properly and operating correctly.

·         The POST results are compared with data in a CMOS chip on the motherboard. If the POST completes successfully, the BIOS searches for specific operating system files called system files.

·         Once located, the boot drive (the drive from which your personal computer starts), loads the system files from storage (the hard disk – usually drive C) into memory (RAM) and executes them.

·         Next, the kernel of the operating system loads into memory and takes control of the computer.

·         The operating system loads configuration information. In Windows XP, the registry consists of several file that contain the system configuration information.

·         When complete, the Windows XP desktop and icons display, and programs in the Start-Up folder are executed.

Describe the term user interface

A user interface controls how you enter data and instructions and how information displays on the screen. Two types of user interfaces are command-line and graphical.

·         With a command-line interface, you type keywords or press special keys to enter data or instructions.

·         A graphical user interface (GUI) allows you to use menus and visual images such as icons, buttons, and other graphical objects to issue commands.

·         A menu is a set of commands from which you can choose.

·         An icon is a small image that represents a program, an instruction, a file, or some other object.

Explain features common to most operating systems

Most operating systems perform similar functions that include managing programs, managing memory, scheduling jobs, configuring devices, accessing the Web, monitoring performance, providing housekeeping services, and administering security. Managing programs directly affects your productivity.

·         A single user/single tasking operating system allows only one user to run one program at a time.

·         A multitasking operating system allows a single user to work on two or more applications that reside in memory at the same time.

·         A multi-user operating system enables two or more users to run a program simultaneously.

·         A multiprocessing operating system can support two or more CPUs running programs at the same time. Managing memory involves assigning items to an area of memory while they are being processed. The purpose of memory management is to optimize use of random access memory (RAM).

·         With virtual memory (VM), the operating system optimizes memory by allocating a portion of a storage medium, usually the hard disk, to function as additional RAM.

·         Scheduling jobs (operations the processor manages) involves determining the order in which jobs are processed.

Spooling increases efficiency by placing print jobs in a buffer (an area of memory or storage where data resides while waiting to be transferred) until the printer is ready, freeing the processor for other tasks. Configuring devices establishes communication with each device in the computer. A device driver is a small program that tells the operating system how to communicate with a device. Accessing the Web may entail including a Web browser and e-mail program in the operating system. Monitoring performance helps to identify and solve system problems.

A performance monitor is a program that assesses and reports information about various system resources and devices. Providing housekeeping services entails performing storage and file management functions. A file manager performs such functions as formatting and copying disks; listing the files on a storage medium; checking the amount of used and unused space on a storage medium; organizing, copying, deleting, moving, and sorting files; and creating shortcuts (icons on the desktop that run a program when clicked).
Administering security involves establishing user accounts on a network. Each account typically requires a user name and a password to log on, or access, the network.

Know the difference between stand-alone operating systems and network operating systems

A stand-alone operating system is a complete operating system that works on a desktop or notebook computer. A network operating system (also called network OS or NOS) is an operating system that supports a network. A network is a collection of computers and devices connected together via communications media and devices such as cables, telephone lines, and modems. In some networks, the server is the computer that controls access to the hardware and software on a network and provides a centralized storage area. The other computers on the network, called clients, rely on the server(s) for resources.
