INTERNET

1. The Internet is a computer-based worldwide information network. The_ Internet is composed of a large number of smaller interconnected networks called Internets; These Internets may connect tens, hundreds, of thousands of computers, enabling them to share information with each other and to share various resources, such as powerful supercomputers and databases or information. The Internet has made it possible for people all over the world to effectively and inexpensively communicate with each other. Unlike traditional broadcasting media, such as radio and television, the Internet is a decentralized system. Each connected individual can communicate with anyone else on the Internet, can publish ideas, and can sell products with a minimum overhead cost. In the future, the Internet may have a dramatic impact on higher education and business as more universities offer courses and more companies offer goods and services online.

2. Individuals, companies, and institutions use the Internet in many ways. Businesses use the Internet to provide access to complex databases, such as financial databases. Companies can carry out commerce online, including advertising, selling, buying, distributing products and providing after-sales services. Businesses and institutions can use the Internet for voice and video conferencing and other forms of communication that allow people to telecommute, or work from a distance. The use of electronic mail over the Internet has greatly speeded communication between companies, among coworkers, and between other individuals. Media and entertainment companies use the Internet to broadcast audio and video, including live, radio and television programs; to offer online chat, in which people carry on discussions using written text; and to offer online news and weather programs. Scientists and use the Internet to communicate with colleagues, to perform research, to distribute lecture notes and course materials to student, and to publish papers and articles. Individuals use the Internet for communication, entertainment, finding information, and to buy and sell goods and services.

3. The Internet is based on the concept of a client-server relationship between computers, also called a client /server architecture. In a client /server architecture, some computers, act as servers or information providers, while other computers act as clients, or information receivers. The client /server architecture is not one-to-one-that is, a single client computer may access many different servers, and a single server may be accessed by a number of different client computers^ Prior to the mid-1990s, servers were usually very powerful computers such as mainframes or supercomputers, with extremely high processing speeds and large amounts of memory.

4. Personal computers and workstations, however, are how capable of acting as Internet servers due to advances in computing technology. A client computer is any computer that receives information from a server and is often a personal computer. To access information on the Internet, a user must log on, or connected, to the client computers host network. A host network is a network that the client computer is part of, and is usually a local area network (LAN). Once a connection has been established, the user may request information from a remote server. If the information requested by the user resides on one of the computers on the host network, that information is quickly retrieved and sent to the users' terminal. If the information requested by the user is on a server that does not belong to the host LAN, then the host network connects to other networks until it makes a connection with the network containing the requested server. In the process of connecting to other networks, the host may need to access a router, a device that determines the best connection path between networks and helps networks to make connections.

5. A major challenge facing the continued growth of the Internet is the difficulty of providing enough bandwidth to sustain the network. As Internet applications become more sophisticated, and as more people around the world use the Internet, the amount of information transmitted across the Internet will demand very high bandwidth technologies, it is not known whether the technology will be able to satisfactorily keep up with demand.

1. The Internet has made it impossible for people all over the world to effectively and inexpensively communicate with each other.

2. The Internet is a computer-based worldwide information network.

3, Servers are usually very powerful computers such as mainframes or supercomputers, with extremely high processing speeds and large amounts of memory.

4. The Internet is based on the concept of a client-server relationship between computers, also called only server architecture.

5. If the information requested by the user is on a server that belongs to the host LAN, then the host network connects to other networks until it makes a connection

6. The use of electronic mail over the Internet has greatly speeded communication between companies and between other individuals.

7. Individuals, companies, and institutions use the Internet in many ways.

8. In the past, the Internet might have a dramatic impact on higher education and business as more universities offered courses and more companies offered goods and services online.

9. Prior to the mid-1990s, servers were usually very powerful computers such as mainframes or supercomputers, with extremely low processing speeds and small amounts of memory.

10. A host network is a network that the client computer is part of, and is usually a local area network (LAN).

11. Like traditional broadcasting media, such as radio and television, the Internet is a decentralized system.

12. Personal computers, however, are how capable of acting as Internet servers due to advances in computing technology.

13. Individuals use the Internet for communication, entertainment, finding information, and to buy and sell goods and services.
