Computer Peripherals

In today’s digital world, computer peripherals are a necessary part of our lives. From printers to keyboards to mice and more, these add-ons help us use computers more effectively and efficiently.

Without them, we would be unable to communicate online, share files with colleagues or print out important documents. Whether you are a student, professional or gamer, having the right peripheral devices can make all the difference.

When selecting peripherals for your computer setup, it is important to consider your needs and budget before making a purchase decision. Think about what type of tasks you need to perform on your computer and buy tools that will allow you do those tasks better.

What Are Computer Peripherals?

Computer peripherals are devices that are connected to computers and provide additional functionality. Peripherals are essential tools for any computer user, as they can help expand the capability of a device beyond its basic operation.

Different types of peripherals exist, ranging from input devices such as keyboards and mice to output devices like monitors and printers. Additionally, there is an entire range of peripheral storage and communication products like external hard drives, modems, scanners and cameras.

Peripheral devices allow users to interact with their computers in ways not possible without them; for example, a keyboard enables text entry that would be impossible without it.

Similarly, a monitor or printer allows users to view the output from the computer on a physical medium. Furthermore, peripherals such as cameras can capture images or videos that cannot be produced by most computers directly.

Types of Computer Peripherals

There are many different types of computer peripherals that can be used with a computer. Some of the most common types include:

  1. Input devices: These peripherals allow users to input data into a computer, such as a keyboard, mouse, or touchscreen.
  2. Output devices: These peripherals allow a computer to output data, such as a printer, monitor, or speaker.
  3. Storage devices: These peripherals allow users to store data on a computer, such as an external hard drive or a USB flash drive.
  4. Communication devices: These peripherals allow users to communicate with other devices or computers, such as a modem or a network card.

Input Devices

Input Devices are pieces of hardware that allow users to interact with their computers.

Keyboards, mice, gamepads, scanners and touchscreens are examples of input devices commonly used today.

All these devices allow users to input data into their computers in order to perform certain tasks more efficiently or accurately.


Keyboards are one of the most essential and important computer peripherals. Initially designed to be used with typewriters, today’s keyboards are much more advanced.

There are several types of keyboards, such as mechanical and membrane keyboards, with each offering advantages and disadvantages depending on the user’s needs.

Keyboards also feature different layouts and designs like ANSI and ISO, also we find different keyboard sizes ranging from standard full-size models to compact varieties with specialized keys for gaming or multimedia use.

Additionally, wireless keyboards allow users to conveniently type without being tethered to their desktops or laptops.

With so many options available, there is something for everyone in terms of keyboard selection.

Furthermore, it is important to consider ergonomics when choosing a keyboard; an ergonomic design helps reduce hand fatigue and strain that may be caused by extended typing sessions.


It is a device used to control the movement of a cursor on a screen and other functions within software programs.

The mouse was invented by Douglas Englebart in 1964(in lab), and has since become an indispensable part of using computers for everyday tasks.

Today, there are many different types of mice available with features such as wireless connectivity, multiple buttons, programmable settings, and trackballs.

Most mice now come with optical sensors that use laser or LED lights to detect motion on surfaces like desks or tables.

This makes them more precise than their predecessors which relied on mechanical parts like wheels or balls to move cursor around the screen.

Some gaming mice even feature additional functions such as side buttons, adjustable weights or special grips to improve accuracy when playing video games.

Output Devices

Output Devices include components used to display information from a computer such as monitors, projectors or printers; they provide users with visual feedback on their actions or commands given by the computer.

Computer Monitors

Computer monitors are an essential part of any computer system. They are the most important visual display device which allows users to interact with the computer.

Without a monitor, the user will be unable to see the output from programs and applications running on their computers. Monitors come in various sizes, shapes and resolutions; offering a wide range to choose from.

The evolution of monitors has been quite rapid over the last few years; with larger screens becoming increasingly affordable and higher resolutions being available every year.

With advances in technology, new models of monitors also come with features such as built-in speakers, multiple ports for connecting external devices and adjustable brightness levels that can be adjusted according to ambient lighting conditions.
