What is terabyte

There are units like seconds to measure time, decibels to measure sound, mm to measure distance and grams to measure weight, similarly units have been determined to measure storage capacity in the computer world. Let us first look at the units of storage capacity in the computer world-

Let’s start with the smallest units. The smallest unit of computer memory is a bit. When four bits are combined, it is called a nibble. That is, 1 nibble = 4 bits. Byte is a group of 8 bits. it is said.

Normally, when you type a number or letter in your computer, it is expressed by a byte or simply speaking, it occupies a space equal to one byte. That is, 1 byte = 8 bits = 2 nibbles. Thus a group of about 11099511627776 bytes is called a terabyte and about 2 million MP3 can be stored in a terabyte.

A kilobyte is 103 or 1,000 bytes.
A megabyte is 106 or 1,000,000 bytes. = 1024 kilobyte
A gigabyte is 109 or 1,000,000,000 bytes.= 1024 megabyte
A terabyte is 1012 or 1,000,000,000,000 bytes.= 1024 gigabyte
A petabyte is 1015 or 1,000,000,000,000,000 bytes.= 1024 terabyte
An exabyte is 1018 or 1,000,000,000,000,000,000 bytes.= 1024 petabyte
A zettabyte is 1021 or 1,000,000,000,000,000,000,000 bytes.= 1024 exabyte
A yottabyte is 1024 or 1,000,000,000,000,000,000,000,000 bytes. = 1024 zettabyte

What is Output Device:-

Output Device: – Based on the command given by you, the output of the processed information is given to you by the computer, which is received by the output device or output unit. Out device is hardware. The best example of output device is your computer monitor. These i/o devices are called –

printer –

Printer is an output device that converts soft copy into hard copy.

What is Input Device:-

Input devices Input devices are such that data and commands can be stored or entered in the computer. The input device converts the data and instructions stored in the main memory into binary. Let us know about the Input Device.

Input Device

Your most commonly used input device is the keyboard, with the help of which you can easily type on the computer. There has been a lot of development in the input device, in which there is no need to type the data. Some of these types of devices are your mouse.

Light Pen, Graphic Tablet, Joy Stick, Trackball and Touch Screen, all these devices provide freedom to the user to select the necessary things on the monitor screen by just pointing, hence these input devices are also called Pointing devices. High level of input device usage Even you do not need to type, only by speaking, you can type with the help of voice input recognition technology. This is a hardware device that can input any data or command from the computer.
