Computer Hardware Basics

Friends, in our last post we have learnt about the basic parts of computer system. In this post we shall discuss about Computer Hardware. As all of us know, the Hardware refers to the physical components of a computer system. In simple words the hardware is the parts of the computer, which people can see, feel and touch. All computer require the following hardware components to perform. 

1. Central Processing Unit (CPU)
2. Memory
3. Input and Output Devices
4. Storage

In addition to the above mentioned components, there are many other inner components which make the basic components work together in an efficient way. Examples of those inner components are Mother board, several electronic boards (cards) and slots, bus, a maze of wires and cables etc. Apart from these devices communication and network devices allow the computer to communicate with other devices. Common common communication devices are modems and Ethernet cards. 

How these hardware components coordinate with each other to make computer work ?

The computer cannot collect the data on its own. As the users of computer, its our responsibility to supply the data to the computer through an Input Device (keyboard, mouse, voice recorder etc). The Input Device receives the data in the form of instructions from users. This received data is either processed by CPU (you can also call it as a processor) or stored in memory for further reference. The instructions stored in memory determines the processing operations. The results of processed operations are either stored in the memory / storage devices or sent to connected Output Devices. The data transfers are determined by software instructions which identify the devices involved. The control unit, a part of CPU, controls and coordinates all these activities. You can check the images of these hardware parts below. We shall discuss the functionalities of these components in detail in our next post. Happy Reading :)
