Data Storage in a computer

Data in a computer is stored in a pattern consisting of a number of concentric circle similar to the one you see in a record player. These concentric circles are called as TRACKS and each track is divided into a number of blocks called SECTORS. The data is stored in a special language called Binary Language as the computer can only understand this language. The Binary Language consists of the Digits 1 and 0.. means all the information is converted to 1's and 0's and then stored in the disk... The 1 , 0 are called as bits and to store one character ( character means it consists of Alphabets , Numerals or any thing like * / @ $ ....) ,the computer uses a combination of 8 bits.. Now these 8 bits are together called as 1 byte .. so we have8 bits = 1 byte1024 bytes = 1 kilobyte (KB)1024 Kb = 1 Megabyte (MB)1024 Mb = 1 Gigabyte (GB)
