Computer is an electronic devices for storing and processing data typically in binary form according to instruction given to it in a variable program,computer consist types of storage device which are primary computer storage device and secondary device PRIMARY COMPUTER STORAGE
The primary storage device is the storage location that normally hold memory for short period of time while it s on, it consist of (RAM) random access memory and (ROM) read only memory.
RANDOM ACCESS MEMORY
The Random Access Memory is used for storing information temporarily. When the computer is switched off, the information on the RAM is wiped off. The amount of RAM directly affect a computer performance the more RAM a computer has the more program and document it can have open withought slowing the system down.
READ ONLY MEMORY
It is used to permanently store data. either when the computer is being manufactured or by the computer user. However, the disadvantage of this type of memory is that the data stored on ROM cannot be changed. The access rate necessary to get to the memory is much lesser as compared to the access rate of the RAM. .

MEMORY CARDS
A memory cards is an electronic flash memory data storage device used for storing digital information . They can be used in various electronic devices from hand held computers, mobile phones and cameras. They are also rewritable. Although they are small in size, they can store a high amount of data

USB FLASH DRIVES
It has an integrated Universal Serial Bus (USB) interface. They are non-volatile and data can be rewritten on them. They are very small in size, but have very large memory space. .

DIGITAL VERSATILE DISC
The format of storing data in the digital versatile discs (DVD) is similar to that of a compact disc. The difference lies in the storage capacity. There is six times more storage space in the DVD's as compared to the CD's. Like the CD's, DVDs are also used as backup device

MEMORY FLASH
With a lot of research came the flash memory. This storage devices for a computer is similar to the read only memory. However, there is a big difference between the flash memory and the ROM. Data from the flash memory can be erased in a matter of few seconds from the flash drives, which is not the case with the ROM's. At the same time, the data can be changed as per the requirement

FLOPPY DISC
This is a magnetic storage device, which is set in square plastic shell. They are available in different sizes, like 8 inches, 5 ¼ inches and 3 ½ inches. In the initial days floppy discs were very popular, however, with the advancements they got over shadowed by the other devices.

COMPACT DISCS
Previously compact discs (abbreviated as CD) were used only for recording and storing audio files. Subsequently along with audio, video and other data is also stored on them. These discs can store data for long time. The data is stored on the CDs in optical format. Backup can be stored on the CDs

HARD DRIVES
The hard drives are one of the most important of the secondary types of computer data storage devices, the hard drive types. Data is stored on the hard drives in the digital format on the hard drives. In the initial days of the computers, hard disks were like removable mass storage devices. However, with time they started coming as a part of the central processing unit of the computer. However, now there are external hard drives available as well.
