What is the Internet?
The Internet is a worldwide communications system that allows millions of computers to exchange information.
The Internet can also be defined as a worldwide collection of networks that links computers of millions of businesses, government agencies, educational institutions and individuals.
A network is a group of two or more connected computers. Connected computers are computers which can exchange files, messages and other information with each other.
How the Internet began?
The Internet began in the United States but didn’t belong to the United States. The Internet does not belong to anyone, no one controls the internet. The Unite States Government wanted a way to connect several computers and transmit information between them. This connection would allow researches based in different countries to exchange information or data.
There was no Internet up until the late 1960s.
Having the connection between several computers
2)The internet is when we connect computers together from anywhere over the world through routers and servers. Three popular uses for the internet are communication,research and education.
The Internet is a worldwide, publicly accessible series of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP).
The beginning of the Internet is well known. It was a United States Defense research program named ARPANET. The internal structure of ARPA that reared the network development during its first years is not as well known. Inventing the Internet explains how the little agency was created in 1958 to respond to the Soviets' successful launch of the world's first artificial satellite. ARPA did not own a laboratory.
Internet – The internet is easily accessible and used worldwide. It is a global network and you can find a wide range of information on any topic via the internet. You can gain access on to the internet by using a variety of different appliances;
Never has a communications system played so many roles in our lives--or exerted such broad influence over our thoughts--as the Internet does today.
I would define a network as a group of computers that are connected together with physical cables or wireless capabilities along with a series of peripheral devices such as, routers, switches, servers or printers etc…for sharing data, software and other resources between different users. When talking about bandwidth, it is a range of frequencies or wavelengths in which data is transmitted. With digital devices, bandwidth is calculated by bits per second or bytes per second and with analog devices, by cycles per second, or hertz.
The Internet- The global network formed by interconnecting most of the networks on the planet, with each home and company network connecting to an Internet service provider (ISP), which in turn connects to other ISPs.
The Internet is, quite literally, a network of networks. It is comprised of ten thousands of interconnected networks spanning the globe. The computers that form the Internet range from huge mainframes in research establishments to modest PCs in people's homes and offices. Despite the recent hype, the Internet is not a new phenomenon. Its roots lie in a collection of computers that were linked together in the 1970s to form the US Department of Defense's communications systems. Fearing the consequences of nuclear attack, there was no central computer holding vast amounts of data, rather the information was dispersed across thousands of machines. A set of rules, of protocols, known as TCP/IP was
The Internet - The Good, the Bad, and the Ugly The internet is a computer based global information system. It is composed of many interconnected computer networks. Each network may link thousands of computers enabling them to share information. The internet has brought a transformation in many aspects of life.
The internet matured in the 1970's as a result of the Transmission Control Protocol/Internet Protocol (TCP/IP), which is sill used today. It was adopted by the U.S. Department of Defense in 1980, and universally adopted in 1983. The usage of TCP/IP is what unites all elements of the net. Both public domain and commercial implementations of the roughly one hundred protocols of the TCP/IP protocol suite became available in the 1980's. During the early 1990's, Open Systems Interconnection (OSI) protocol implementations also became available by the end of 1991, the Internet has grown to include some 5,000 networks in over three dozen countries, serving over 700,000 host computers used be over 4,000,000 people. By December 1996, about 627,000 Internet domain names had been registered and now there are more than 30 million registered.
In today’s world Internet has become one of the most important mediums of communication. It has become the lifeline of our survival. It has removed the entire social, economic and physical barrier and has immense effect on our day to day activity.
Internet - (p. 301) an international network of computer servers that provides individual users with communications channels and access to software and information repositories worldwide.
A computer network is a network that consist of two or more computers that are able to share information between them or their users. There are a large variety of different networks and the advantages or disadvantages are strongly related to the type of network we choose.
The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail.
A network enables all PCs and devices to exchange data with each other which means they can all communicate with each other with information and data.
