Understanding Computer Network

Today networks have become one of the most important components in businesses throughout the world, but it only exists to provide a medium for the computer to communicate. Much like roads provide a medium for cars, the computer network allows computer to move data from one system to another. Without networks any operation which involves the communication of computers such as Online Banking, instant messenger, and many more will not be possible.

In order to fully understand computer network, you should at least be familiar with computer components such as the processor, bus, storage units, and expansion cards.

Personal Computer Component

CPU - Central Processing Unit. The main processor for a computing devices. The CPU runs the instructions instruct by the OS
RAM - Random Access Memory. A type of volatile memory that can be read and written, by the microprocessor.
Storage Devices
Expansion Bus - A signaling path made up of wires or other media that allow electronic signals to be sent from one part of a devices to another.
Input Output Devices - Devices which are use to input the data and output its data to the user.
NIC - Network Interface Card. The devices which allows workstation to connect to the network and communicate with another computer.

Types of Networks

Computers can be positioned on a network in different ways relative to each other. Different types of network have different level of control and shared resources. There are two fundamental types of networks model:-

1. P2P (Peer-to-Peer)
2. Client/Server
