(system open for attack). 4. What type of security was dominant in the early years of computing? Security‚ in its earliest years‚ consisted of mainly physical security‚ the need to safeguard the equipment itself. During the next decade‚ when ARPANET grew in use‚ more advanced security was needed. This led to the creation of MULTICS‚ an operating system with security being its main concern. From MULTICS spawned the UNIX operating system which did not require the same in-depth levels of security

WIRELESS TECHNOLOGY INTRODUCTION Technology continues to develop very quickly down to the corner of the world‚ but not with strong will and hard work‚ information technology‚ chaired by the computer becomes a linear phenomenon with the development progress of the age. The development of information technology is developing very rapidly‚ this development can not be separated from the ability of computers to perform data communication and also establish a computer network both

justifies the age old saying that necessity is the mother of all inventions. The need to share information in a so called ‘global network’ and man’s desire to communicate from long distances called for the birth of the World Wide Web (formerly known as ARPANET). With the advent of the internet‚ many of the mundane tasks and businesses that people conducted were made feasible. Things like buying and selling various products can now be done online. The consumer no longer needs to moves from his location.

data interchange. In the late 1970s a new protocol was developed known as ASC X12 which was used for the exchange of business documents and information electronically. Another system was being developed at the same time by the Military known as ARPAnet‚ and was the first to use the "dial up" method of sending information via telephone networks. It was considered the grandfather of the modern Internet. I guess we can thank the cold war for something! In 1982 Transmission Control Protocol and Internet

exchange and the World Wide Web. E-commerce has developed over a long period of time. It has developed hand in hand with the internet. The earliest recorded instances of e-commerce include the use of the Advanced Research Projects Agency Network‚ (ARPANET)‚ by students at the Stanford Artificial Intelligence Laboratory and the Massachusetts Institute of Technology to arrange cannabis sales between themselves in 1971. A great leap occurred in 1979 when Michael Aldrich demonstrated his first online shopping

I will also define Human-Computer Interaction (HCI) . I will be utilizing the 5W+H (What‚ Where‚ When‚ Who‚ Why and How) analytical format .

In 1960‚ Cassettes are introduced in a new format‚ Telstar satellite relays telephone and TV signals‚ and ARPAnet research has begun for the Internet. By the end of the 1970s‚ e-mail and microprocessor are developed‚ and video is now available on VHS.

Ans. Yes‚ I do believe that Internet is solely responsible for the industrial revolution. In the mid-90s’ ARPANet was transformed from a military safety net to the civilian Internet that has become such an integral part of our lives‚ bringing with it change not only technological but also change for the society as well. The Internet results in bringing a revolution along with it access to any kind of information combined with reshaping established conventions and destroying old world definitions
