### What are a bit, Nibble and Byte?

Computer memory is an electronic chip which consists of millions of transistors and capacitors. A transistor and a capacitor are paired to create a memory cell that stores one bit of data. Such 4 bits form a Nibble and 8 bits form a Byte.

Many modern computers are byte-addressable which means for each byte we have a unique address and the data can be fetched only in the multiples of bytes.

For example, if you want to read 4 bits of info, then you need to read the entire 1 Byte of data and perform shifting operations to get the required 4 bits of data.
