Types of Information Technology

Information technology (IT) covers the application of computer technology to the development of information systems and communication between computers. It is also sometimes referred to as computer networks. Information technology is generally used in the context of business operations rather than private entertainment or personal technology.

Information technology is used to enable computers to communicate and work in an organized manner. The communication is usually done through networks that are typically made up of hardware devices and software applications that interact with each other. These networks are usually categorized as public or private. The main categories are private, public, hybrid and open networks.

Public networks can be accessed from any computer or network connected to a public network. A public network typically includes public telephone lines, local network switches and central server or router. Private networks are normally classified as being located on a leased or rented area where they are protected by security measures such as encryption.

On the other hand, information technology that is considered public is generally found in networks of computers owned by a government agency such as a telecommunications company or a department store. Private networks include personal computers owned and used by the owner. Such a computer is considered private because the owner does not share the private information with anyone else.

Hybrid networks are networks where some components are in public networks and some components are in private networks. In such networks, some computers in public networks are linked to some computers in private networks. Open networks are networks that allow people to connect privately to each other. Hybrid networks are networks that contain private and public elements.

The use of information technology involves a number of activities. The most important activity is the creation of networks to exchange information. These networks are usually classified in two main types: private and public. Public networks are typically owned by a government agency or organization such as a university. Private networks are usually owned by private individuals and organizations.

In private networks, computer users communicate through their private networks and share personal information such as e-mail addresses, files and instant messages. between each other. Public networks include publicly accessed computers or networks. They are normally connected to a public network through leased or rented connections.

As previously mentioned, a private computer network is connected to a public network through leased or rented connections. or to a public network through either physical connections or through the Internet. Public networks are usually accessible by network users and are usually accessible for users on a residential, small to large scale basis. They can also be used by large companies, schools and colleges. These networks are usually classified into two main categories: hybrid and public.

Large businesses, schools and universities often have private computer networks that include private networks and public networks. This allows them to exchange information from one place to another. Hybrid networks can be used by a school or university to connect computers that belong to different departments to one another without actually sharing the public networks.

Private networks are much more secure and easier to protect than public networks. Public networks are more susceptible to security breaches due to external sources. Some of the possible security breaches include virus attacks, hacker attacks, Trojan attacks and data theft.

One of the primary benefits of using private networks is the fact that they are easier to protect than public networks. However, the main disadvantage of private networks is that they are more expensive than public networks.

Private networks provide users access to resources that are limited while public networks are available to access many resources at the same time. Public networks are easy to protect from external sources since the private network is not accessible by others. On the other hand, private networks provide users with the ability to use and install applications on their own computer.
