Task: Complete questions 1 - 11 on pages 112-113 on the textbook Discovering Computers.

1. How did the Internet evolve?

The internet, also called the Net, is a worldwide collection of networks that links millions of business, government agencies, educational institutions, and individuals. The Internet has its roots in a networking project started by the Pentagon’s Advanced Research Projects Agency (ARPA), an agency of the US Department of Defense. ARPA’s goal was to build a network that allowed scientists at different locations to share information and work together on military and scientific projects and could function even if part of the network were disabled or destroyed by a disaster such as a nuclear attack. The network called ARPANET, became functional in September 1969, linking scientific and academic researchers across the United States.

As researchers and others realized the great benefit of using ARPANET to share data and information, ARPANET underwent phenomenal growth. By 1984, ARPANET had more than 1000 individual computers linked as hosts. Today more than 550 million hosts connect to the internet.

Some organizations connected entire networks to ARPANET to take advantage of its high-speed communications. In 1986, the National Science Foundation (NSF) connected its huge network of five supercomputer centers, called NSFnet, to ARPANET. This configuration of complex networks and hosts became known as the internet.

Task: Complete questions 1 - 11 on pages 42-43 on the textbook Discovering Computers.

Questions and Answers:

1. Why Is Computer Literacy Vital in Today’s World?

Computer literacy is important in today’s world because the whole world nowadays is rounded by technology. Every human being on the planet has to have the ability to have the current knowledge and understanding of computers and their uses. Technology also changes as time changes itself. Computer literacy is very vital to success.

2. What Is a Computer, and What Is the Relationship between Data and Information?

Computer is a digital machine which operates under the control of instructions and commands which has a memory and can process data according to the input data given, and processes the data according to the commands stored on itself or the commands we give which the computer understands. Data is a collection of data which aren’t processed yet by the computer. Information is a form of data, which has already been processed by the computer.

3. List and Describe the Five Components of a Computer.

The computer consists of five components, they are: Input devices, output devices, system unit, storage devices, and communication devices. An input device allows us to input our own data into the computer. An output lets the computer show information to other people. The system unit is a place where the computer stores data that are processed. In a storage device, a computer records items from storage media. A communication device lets a computer send and receive data, instructions, and information to another computer.

4. What Are the Advantages and Disadvantages That Users Experience When Working with Computers?

There are lots of advantages and disadvantages when working with computers. Computers have of course the good speed for finishing a job because it lets us get our job done quickly.

5. What Is a Network, and What Are Its Benefits?

A network is a collection of computers who are connected in one place with supporting devices where we can share resource. A network usually has supporting hardware and software to share resources, files, data, and information in one single place. A simple example would be the network in Binus University.

6. How Are the Internet and World Wide Web Used?

The internet and world wide web is used to communicate between one person and another which can be done with various programs like LINE, Skype, and so on.

Whereas system software consists of the programs that control the operations of the computer itself, and its devices. There are two types of system software: operating system and utility programs.

8. What Are the Differences among the Types, Sizes, and Functions in the Following Categories: Personal Computers (Desktop), Mobile Computers and Mobile Devices, Game Consoles, Servers, Mainframes, Supercomputers, and Embedded Computers?

A Personal computer, or usually called PC, is a computer that can perform most of the instructions like input, process, and output and storage activities all by itself. A mobile computer is a personal computer which you can carry easily to one place to another and very portable. A mobile device is also like a mobile computer, only small enough to fit in the palm of your hand. A game console is a computing device designed for a one player or even multiplayer games. Servers controls access to its hardware, software and resources on network, and has a storage area for its programs, data, and information. A mainframe is a large, expensive, and powerful computer, which can handle lots and lots of connected users at the same time, and can store tremendous amounts of data. A supercomputer is known as the fastest, most powerful, and expensive computer, usually used in big companies like FBI, etc for applications which are complex, sophisticated and mathematical. An embedded computer is a special purpose computer that functions as a component In a product larger than itself.

9. What Is the Role of Each Element in an Information System?

An information system is the combination of hardware, software, data, people and procedures which can produce information in the most efficient way possible. People in the IT department develop procedures which processes the data. Following the procedures from the people from IT department, people use hardware, and software to enter a data into a computer, which is then processed by the computer and store changes on storage media with the information in a desired form.

 10. How Do the Various Types of Computer Users Interact with Computers?

Power users exist in all types of business like, an enterprise user works in or interacts with a company with lots of employees and uses a computer or computer network powerful enough to process lots of transactions per day.

11. How Does Society Use Computers in Education, Finance, Government, Health Care, Science, Publishing, Travel, and Manufacturing?

Society use computers in education for learning, like online classes, or sometimes help with doing school work. In terms of finance, people can use the computer for doing online banking, or also do online investing online on the internet. The government uses computers to provide the latest information to their own citizens, they also use computers to help them with their work. In health care, computers can be used to store the patients records, monitor them, and deliver medication to nurse stations. They can also be done to store the payment data of the patients. In science, computers are very helpful in storing data, analyzing the data given, modeling the data into a graph, or diagram, and they can be used to communicate with other scientists or researchers around the world. Publishers use computers to assist them in designing pages and they can post their work online too. Transportation use online navigation (GPS) to help people travel more accurately and efficiently. Manufacturers use computer-aided manufacturing to assist with manufacturing processes.
