However, by now you must have understood a little bit about the difference between these two. Whereas small 'b' is used to represent bits.īit and Byte are both units of computer memory, but there are several basic differences between the two. Here it is important for you to know that capital 'B' is always used for bytes. In computers, the term Bytes is often used to measure data storage.įor example, a hard drive can be 250 GB (Gigabytes). More Bytes are used to store large-size data.įor example, #kilobyte (KB) which contains 1,024 bytes, megabyte (MB) which is equal to 1,024 kilobytes, gigabyte (GB) which is equal to 1,024 megabytes, similarly terabyte (TB) which is 1,024 gigabytes. That is, a series of eight zeros and one (10101100) is considered a byte, which can store a single character such as the letter B, the number 5, and a graphic symbol. So bit is the smallest piece of computer data whose value can be 1 or 0.Ī group of 8 bits is called a byte. For example 1Mbps (1 megabit per second) internet speed, here the small 'b' stands for a bit. Data transfer speed is always measured in bits. So bits are the basic unit of data storage in a computer.įour #bits (1001) together form a nibble, which is also called a half byte. So whenever the transistor is ON, we consider it as '1', while when it is of that condition is considered as '0'. Each transistor is a small switch, which is activated by the electronic signals it receives. There are billions of transistors in the circuit of a computer processor. This means that the data in the computer is stored in the form of zero (0) and one (1) (this is called machine language). The binary number system calculates using only a combination of two digits (0 and 1). As you know, computers use Binary Number System to store all types of data like numbers, words, videos, music, and pictures, etc. #Bit or Binary Digit is the smallest unit of information (data) on a computer.
