bit
The smallest addressable unit of storage on a disk is called a sector.
A byte (character) is the basic storage unit in memory.
The smallest storage access unit on an IDE hard drive is a sector.

It is the memory capacity of the storage unit.
It is called a block (or sector). The size of the block varies depending upon the size of the disk, advanced preferences (the size of files normally being used on that disk), and the filesystem being used. They normally run from 512Bytes to 64KiB. As disk capacity continues to grow, look for even larger block sizes to come :-)
The smallest unit of measurement used to describe the storage capacity of a computer is called a bit. It is a binary digit that can represent either a 0 or a 1, and is the basic building block of all digital data.
GB(Gygabytes) or MB(megabytes)
central processing unit comprising of arithmetic logic unit and control unit, and RAM i.e.the internal memory
The smallest unit of memory in computing is a bit, which can hold a value of either 0 or 1. A group of eight bits forms a byte, the fundamental building block for data storage and processing. In modern computing, memory is organized in larger units, but bits remain the basic measurement of digital information.
