Computer Peripheral Devices

Introduction Of Computer Peripheral Devices:

To know about computer peripheral devices, First of all, we have to familiar with data and information. A computer is such an electronic device that accepts data and information. How does it work? Let us define, At first, It keeps data and information in its own memory. Then, the computer processes the data and information. After then, it gives a desired output through the computer output devices.

If the data and information stored in the past, and we want that from the computer, we easily get it from the computer because it has the capacity to store and information. All computer has its own hardware and software. We can call these hardware peripheral devices in one word.

A computer is an electronic machine. In short, it performs arithmetic and logic operations. Moreover, computer devices consist of both electronic and electromechanical components.

The electronic devices include the Integrated Chips (IC). It present in the motherboard and also, in other components. On the other hand, electromechanical devices include the motors in Floppy disk Drive, Hard Disk Drive, fans, etc.

A personal computer has various applications like word processing, desktop publishing, accounting, database management, etc. In this way, the different peripheral devices of the computer include the following.

Peripheral devices of computer:-

  1. Input Devices
  2. Output Devices
  3. System Unit
  4. Mass Storage Devices
  5. Peripheral connectors

As given below, the diagram shows to process data to Input and Output devices

  1. Input Devices:

A computer’s input device is such a hardware device that we can enter data and information. Therefore, This device easily reads the data and sends it to a system unit. The most important example of an input device is the mouse and keyboard. Similarly, there are also some input devices that we may connect to the system unit.

Input devices provide input to the computer for processing. So, all input devices provide data to a computer. In this way, input devices allow us to enter raw data for processing. Read more…..

Example of Input Devices:
  • Keyboard
  • Mouse
  • Joy Stick
  • Light pen
  • Track Ball
  • Scanner
  • Graphic Tablet
  • Microphone etc…

2. Output Devices:

Similarly, a computer output device is also a hardware device. Whereby, we output the input data through a system unit. This output is received through the output device. Important examples of computer output devices are monitors, speakers, and printers. Besides this, there are many other output devices that we can use in computers.

Output devices take output or result of processed data from the computer. Just to be clear, output devices receive information from the computer and carry data. After that, the computer processes the data through the output device. Read more…..

Example of Output Devices
  • Monitor
  • Printer
  • Audio Speakers
  • Headphones
  • Projector
  • GPS
  • Sound Card
  • Video Card
  • Braille Reader
  • Plotter etc….

3. System Unit :

Whatever is inside the box of a computer, the total unit is called a system unit. Its working process, in short, we can say, The data inputs to this system unit through an input device, Then, it is processed in this system unit. After then, the processed data from this system unit is output through the output device. After all, the main part of this system unit is the CPU. CPU means Control Processing Unit, it controls the data and then processes it, after then, it sends data.

Charles Babbage is considered the father of this CPU.  He invented the first mechanical computer in the 19th century.

The system unit consists of many components, In another way, we may say it is a cabin where all accessories include inside it. For example,

the Motherboard, CPU, Memory, System Bus, Expansion Bus slots, BIOS ROM, Chipset, and other jumpers and connectors for connecting the front panel display LEDs, Power supply unit.

Motherboard :

The mother is a type of PCB board i.e, Printed Circuit Board. Therefore, It holds connections and electronic parts. The main circuit board held in the computer system. Read more ……

CPU :

The Central Processing Unit is also called The Brain of Computer. Also, it is known as a microprocessor. Furthermore, it may say that it is an electronics chip control all function processed on a computer. Read more ……

 

Memory :

This device used to store data information. When required, it may recall for use. Thus, memory used in PC can be broadly classified into two types. Read more…..

 

System Bus:

The bus is a set of wires or conductive paths. These references use electrical connections. Therefore, it uses for transfer of data, address, and a control signal to different components in a computer. Whereas, System bus refers to the single computer bus. This connects to the CPU (processor) with the system memory. On the other hand, the I/O bus connects the CPU with the I/O devices. Read more ……

Expansion Bus Slots:

An expansion bus is another type of computer bus. It transfers information internal hardware computer system to peripheral devices. Since the internal hardware of the computer system includes CPU and RAM. Expansion slots hold the daughter boards. Here, Daughter boards are called Add on cards or interface cards. Read more…..

4. Mass Storage Devices:

Storage Devices uses to store any type of data. That means, it can store a large number of data. The secondary storage devices include the mass storage device. For example,

Hard Disk Drive, Floppy Disk, CD, DVD, Magnetic tapes, Pen Drive, etc….

5. Peripheral Connectors:

Peripheral connectors integrate into the computer to add functionally. For example, mouse, keyboard, monitor, scanner, printer, etc.

Facts of Computer Devices

Day by day, updates appear for the model of computer devices. However, the more we use these devices on the computer, the more it will cost of computers.

So, these computer components, we will also have to install advanced software.

  1. Fantastic items from you, man. I have be aware your stuff prior to and
    you are just extremely magnificent. I actually like what you have bought right here, really like what you’re stating and the way in which through which you assert it.
    You are making it entertaining and you still care for to keep it smart.

    I cant wait to read much more from you. That is really a tremendous site.
