PC Networks for Beginners

Computers have become one of the most important fundamental building blocks of human society. They play an important role in almost all sectors of society, this includes education, health, infrastructure, communication, transport, trade, and information. The underlined importance of computers in these sectors of human society has created the need to create links and channels that aid the transfer and sharing of data and information from one computer to the next, or from one sector of society to the other sector. The transfer and sharing of data and information can be extended across geographical boundaries, this may include boundaries within the city, town or province. Data and information can also be shared across the state or country lines of communication; this may extend from one continent to the other. The wide range of data transfer and sharing by computers can only be achieved through the creation of computer networks. Computer networks are defined as the interconnection of two or more computers in order to communicate and share available resources.

The concepts of computer networks in this article will include, a basic description of a computer network, the components of a network and the basic uses of a network.


What computer network?

A computer network consists of two or more computing devices that are connected in order to share the components of the network (its resources) and the information and data that is stored there. The most basic computer network consists of just two connected computing devices. It can be expanded when additional computers and devices are connected and add their resources to the network. It is worth noting, computing devices are not confined to laptops and desktop computers, but can also include other electronic devices such as; mobile phones, printers, tablets, switches, headsets, smartwatches, TVs, and many other network-connected devices.

Types of Computer Networks
Personal Area Network (PAN)
Local Area Network (LAN)
Campus Area Network (CAN)
Metropolitan Area Network (MAN)
Storage Area Network (SAN)
Wide Area Network (WAN)

Different types of networks are formed when more computing devices are added and connected to a network and share their resources. When the computer network grows, it becomes a more powerful tool. A network connected with more devices has more data and information and is capable of accomplishing more tasks because more additional resources and computer network devices have been added. The real power of networking computers and devices becomes apparent if the network is allowed to grow. The growing network can be connected to other distinct and different computer networks, enabling communication and resource sharing across a number of several different computer networks. The internet is the largest computer network. When you are browsing the internet, you are basically sharing your network resources on a global computer network.

Most computer network users are familiar with network connections within an office, at home or in an institution. Computer network connections can also be extended across geographical boundaries and borders. This may include networks within the city, across country borders or even continents. In order to operate and expand any computer network connection, distinct components of a network are required. These are devices, media, and services. These network components facilitate and aid the transfer of data and information in a network. As the computer network expands, different types of computer network components are required.
