In the 1960s, time-sharing brought about the first interactive access to computers. This was a mix of data transmission technology and a teletypewriter. The result was an interactive terminal. These terminals were connected to a server with low-speed lines, allowing the users to interact with the computer and take advantage of its resources. Time-sharing gave multiple users the ability to use the computer at the same time, for completely separate tasks, and provided them with interactive feedback about what their programs were doing. Demand for the services of these large computers increased which meant upgrades had to be made frequently to keep the processing power ahead of the user.s needs. These systems, called Mainframes, had been designed to provide computing power, but did not have the flexibility to satisfy the growing set of applications.

Military action, also in the 1960s, used networks to communicate to one another. It worked like the time-sharing network. They needed this network to communicate between cities, bases, and states. There needed to be a network that would be able to work after a nuclear strike. They came up with a .hot potato network.. Basically the information would be tossed like a hot potato from user to user until it reached its destination. During the 1970s and 1980s, networking was continuously being upgraded. Businesses, schools, and the government needed faster networking capabilities to handle all the people that were using the basic .time-sharing. network. In 1975 the first personal computer was marketed in kit form. This computer was called the Altair. Bill Gates, with others, wrote a BASIC program for the machine so it could perform small tasks.

The next year Apple began to market its PC.s, also in kit form. In 1976, Queen Elizabeth went on-line with the first royal e-mail message.

The Internet as we know today as the Information Superhighway was introduced in 1989. It was formed through a long chain of networks. It was a lot smaller back then. There was only a handful of people that had a computer, and some of these people were not familiar with a modem. In 1989 the Internet had about 3900 domains and 130,000 hosts. Today there are over 3 million domains and 36 million hosts. In reality the Internet formed through the formation of the ARPANET. The ARPANET was the first stage of networking, and the second stage BITNET. These two early networks were the start of the Internet. It can be said that the Internet is the third step of the network process.

There are several reasons to learn about networks:

§ Resource sharing

§ Reliability

§ Cost savings

§ Communications

§ Employees can share information, such as inventory inf., customer records, or accounting data

§ Employees can swap files without printing them or passing around disks

§ Employees are able to access files and applications on the network from remote computers

§ All employees have access to both the Internet and e-mail

§ Employees can use devices, such as printers and fax machines without leaving their desk

You can see that ever since networking was first introduced people have been constantly trying to improve it and make it faster. This is going to continue for thousands of years. It is important to understand that networking plays an important part in your life.

Many people today are familiar with the Internet and its use. A large number of its users however, are not aware of the security problems they face when using the Internet. Most users feel they are anonymous when on-line, yet in actuality they are not. There are some very easy ways to protect the user from future problems. The Internet has brought many advantages to its users but has also created some major problems. Most people believe that they are anonymous when they are using the Internet. Because of this thinking, they are not careful with what they do and where they go when on the .net.. Security is a major issue with the Internet because the general public now has access to it. When only the government and higher education had access, there was no worry about credit card numbers and other types of important data being taken.

There are many advantages the Internet brings to its users, but there are also many problems with Internet security, business security, and the government involvement to protect the users. The Internet is a new, barely regulated frontier, and there are many reasons to be concerned with security. The same features that make the Internet so appealing such as interactivity, versatile communication, and customizability also make it an ideal way for someone to keep a careful watch on the user without them being aware of it.

Every action a person does while logged onto the Internet is recorded somewhere. An individual.s personal security is the major issue surrounding the Internet. If a person cannot be secure and have privacy on the Internet, the whole system will fail.

Email is like a postcard. E-mail is not like mailing a letter in an envelope. Every carrier that touches that e-mail can read it if they choose. Not only can the carriers see the message on the e-mail, but it can also be electronically intercepted and read by hackers. This can all be done without the sender or the receive
