# Which is Bigger - KB or MB?

When we talk about computer memory, we speak in terms of KB, MB, etc. However, which of the two is bigger is the question most of us face? Let's find out.

Bit

A bit is defined as a variable which can have only two possible values. Each bit denotes the binary value of either 1 or 0, which are interpreted as binary digits. The correspondence between these values of 0 and 1 and the physical states of the underlying storage or device is a matter of convention.

Byte

A unit of digital information in computing and telecommunication is called a byte. It is nothing but an ordered collection of bits. Historically speaking, a byte was the number of bits that were used to encode a single character of text in a computer. Hence, it is the basic addressable element in many computer architectures.

The Result

We have seen what exactly are bits and bytes in computer memory. The next term, which we need to know is kilobyte which is represented as KB. A kilobyte represented in binary is 1024 bytes and is represented as 2

^{10}. It can also be used to represent the 1000 bytes or 10^{3}, which is the decimal interpretation. This may be a little confusing but note that binary KB is bigger than the decimal one by 24 bytes. When represented in the binary system MB is 1,048,576 bytes or 2^{20}bytes and it stands for megabyte. However, in the decimal system, it stands for 1,000,000 bytes or 10^{6}bytes. In the decimal system, MB stands for megabits.1 nibble = 4 bits

1 byte = 8 bits

1 KB (one Kilobyte) = 1024 bytes

1 MB (one Megabyte) = 1024 KB = 1,048,576 bytes

1 kbps = 1000 bits per second

1 mbps = 1,000,000 bits per second
