COMPUTER MEMORY

Computer memory is device that is used to store data or programs (sequences of instructions) on a temporary or permanent basis for use in an electronic digital computer. 

Type of memory

 

Primary memory

Primary memory is the only type of memory which is directly accessed by the CPU. The CPU continuously reads instructions stored in the primary memory and executes them. Any data that has to be operated by the CPU is also stored. The information is transferred to various locations through the BUS. Primary memories are of two types. They are:

1.      RAM

2.      ROM

1.RAM:-

It stands for Random Access Memory. Here data can be stored  temporarily, so this type of memory is called as temporary memory or volatile memory because when power fails the data from RAM will be erased. The information stored in the RAM is basically loaded from the computer’s disk and includes information related to the operating system and applications that are currently executed by the processor

1. ROM:-

It stands for Read Only Memory. In this, the data will be furnished by the manufacturers regarding the system, so this information can simply be read by the user but cannot add new data or it cannot be modified.

    SECONDARY MEMORY

Secondary memory is where programs and data are kept on a long-term basis. Common secondary storage devices are :

1.     Magnetic disks

2.     Magnetic tape

3.     USB flash drive

4.     Mass storage devices

1   1.    Magnetic disks:-

A magnetic disk is a storage device that uses a magnetization process to read, write, rewrite and access data. It is covered with a magnetic coating and stores data in the form of tracks,  spots and sectors. Hard disks, zip disks and floppy disks are common examples

2.Magnetic tap:-

Magnetic tap is a long and narrow strip of plastic that thin magnetic material is coated on. Nearly all recording tape is of this type, whether used for recording audio or video or computer data storage.

3.USB flash drive:-

A USB flash drive (USB stands for Universal Serial Bus) is a popular way to store digital information. Flash drives are an easy way to share data (information). A USB flash drive can be attached to a USB port, and provides a certain amount of storage space, which can be used to store data. USB flash drives are used with devices found in homes, workplaces etc.

4.Mass storage devices;-

A mass storage device (MSD) is any storage device that makes it possible to store and port large amounts of data across computers, servers and within an IT environment. MSDs are portable storage media that provide a storage interface that can be both internal and external to the computer
