storage capacities than ash memory but lesser than laptop hard disk External and removable hard disk is utilized for back up or transferring the file External hard disk is connected to system unit whereas removable hard disk can be inserted or removed Computer Data Storage 5 Floppy disk This has become obsolete after arrival of ash drive and other portable devices with higher data storage capacity It is useful in the case of small files It is slow method of storing data Current products of computer do not create oppy disk drive RAM RAM stands for random access memory which is used for carrying the task of runtime operations It stores the data in integrated circuit form in CPU where each data can be accessed randomly without any association with order of data or location It has second fastest retrieval time of data after cache Once the task is completed RAM releases the memory as it is case of volatile memory Latest series of computer products can provide up to 8 GB of RAM Clock Speed Clock speed of CPU is the speed at which data is processed or microprocessor executes instruction It is expressed in megahertz or gigahertz Expansion buses also similar clock speed like CPU with same frequency Ideally buses and CPU should have same clock speed but buses are slower in practical application CD ROM CDROM is compact disc readonly memory where contents cannot be deleted or changed Its capacity is around 650 MB to 1 GB In recordable CD you can write the content once but it can t be erased whereas rewritable CDs allow to record and write multiple times Arrival of recordable CD has given the option of collecting different set of images audio and video files at your own choice Tape Tape is useful for backups of huge volume of data which has slow data storage time Hence it is advisable to avoid using it in real time Still it is good choice of storage as back up in the case of crash of hard drive It has also become obsolete like oppy drive Computer Data

it as standard device It is compatible with most of the latest PC versions with occasional cases of incompatibility Computer Data Storage References Website Anonymous 2009 Youtube Retrieved June 28
