Which Three Parts Of The Computer Receive Input

Computers are built with many parts, and different parts serve different purposes. Some of these parts are used to process information, some to store information, and others to transfer information. However, one of the most important parts of the computer is that of input. The input port is the part that receives information from the outside world. Input is how your computer can interact and communicate with the world around it.

Which Three Parts Of The Computer Receive Input? There are several parts of the computer that can receive input. But in this article, we will share the three primary parts that receive input. So let’s get started:

An Overview of Which Three Parts Of The Computer Receive Input

There are three parts of the computer that receive input are MICR, Barcode readers, Touch-screens. Let’s discuss them in detail:


MICR is a magnetic storage technology that is used to store data on magnetic stripes. It is commonly used in credit cards, debit cards, automated teller machine (ATM) cards, identification cards, etc. MICR stands for Magnetic Ink Character Recognition. Because it is a magnetic storage technology, data can be read even if the strip is damaged or dirty.

The magnetic strip is composed of a number of tracks, and each of these tracks is composed of a number of a number of characters. Each character is made up of five (5) bits (zeros and ones).

Barcode Readers

A barcode reader is one of the three main devices that receive input to the computer. The other two devices are the keyboard and mouse. The barcode reader is a device that is used to read and process barcodes.

Barcodes are a series of lines and dots that are used to store data in a way that is easier to read by a machine than numbers and letters. The barcode reader is a device that can quickly scan the barcodes and read the data it contains. Once the data has been read, it is sent to the computer for any type of needed processing. This device is used mostly in retail stores to scan the barcodes on products and receive information about the products.

The information can be read and then sent to the computer for processing. Barcode readers are also used to scan tickets for events and concerts to allow the ticket holders to get in. This device is a very important part of the computer because it allows the computer to receive data from outside sources.


The screen is an output device. It is an interface through which an input device may send information to the computer. This information is received by the screen and then sent to the CPU (Central Processing Unit), which then processes the information and sends it to the hard drive. The screen is made up of pixels, which are tiny dots of light. The pixels are arranged in rows and columns to create a grid-like appearance. This is called a raster display.

Moreover, touch-screens are a great way to interact with a computer without using a mouse or keyboard. They are great for entering passwords and numbers. Touch screen computers are extremely useful for people who are physically disabled, who have trouble using a mouse or keyboard. In the past, it was very expensive to have a touch-screen computer. Now you can find them in devices such as ATMs, ATMs, portable gaming systems, and even in some school-owned computers.

Let’s Sum Up

We hope that this blog post has been helpful for you. It might not seem like a difficult question at first, but without knowledge of what each part of the computer does it can be a little hard to answer. Hopefully, you now have a better understanding of the computer and its parts, and can answer this question with ease. If you have any other questions or concerns, please contact us anytime.
