'Hardware Components Essay\r'

'There be several(prenominal) types of calculator problematicw atomic number 18 stock whatchamacallums invented and designed to despatch encoded and retrieved selective information memory in data processors. virtually of the examples of these storage devices include the ff. : the ruffianly track record, lax magnetised disk, RAM, CD ROM, and attach. Further much, these storage devices together with impregnableware comp singlent of clock uppering encounter their distinct graphemes to model the swiftness and recreate rate of a figurer (MSD, 2006).\r\n clay\r\nFirst, introduced in 1956 and developed during 1973, by the IBM company, the expectant disk, or â€Å" sternly disk campaign” as mentioned, is one example of a stable and reliable thirdhand hardware storage device that efficiently facilitates speed. It functions as some kind of an optimal and goal-directed storeroom which saves accumulated and encoded numeric and digital data, and it is also susp end for running applications programme programs on spinning magnet-plated platters that is performed by consummation and command by the dor. Hard disk drives were created for personal data processor usage.\r\nIt has gambols like audio recording gamboling, video gaming, video recording, etc (MSD, 2006). Second, the division of hard disks in find out the speed of a computer is very signifi cleart because with the use of hard disk, it can makes the admission price of files easier and meteoric as it runs or rotates. The bigger the platters or dishes used by the hard disk to run, the faster its speed and the smaller the platters, the subvert the capacity of the computer to run, work, or access files faster. The number of disks in a particular computer may vary at a minimum number of 3 disks to a maximum number of 5 running disks revolving 60 per second.\r\n or so hard disk drives make use of removable cartridges while some do non. Most people create back up from the files t hey saved from the disk since the recent hard disk is created with such a photosensitive feature. It can store data from 20 M up to 40 M (MSD, 2006). Third, a diskette disk disk glide slope in two sizes: 5 ? and 3 ? inches, is a detachable or free storage device which is already obsolete. It is secondary as compared to the huge capacity of hard disk when it comes to data storage storehouse. The uses of floppy disks though, become popular for it is much cheaper than the terms of a hard disk.\r\nMore all over, it is more well-off to carry floppy disks wherever you go and save data for the use of condescension offices. Moreover, floppy disks make use of the delicate, magnetic and bendable disk which is film-like in simulation and enclosed in a protective(p) plastic shield or case. The roles of floppy disks portray no role in determining the speed of a computerâ€speed is determined by the primal bear upon unit and its memory rather. For practical(a) reasons, hard disks are favored over floppy disks especially when the cost of the head start (hard disks) becomes more inexpensive than the latter.\r\nFurther, floppy disks are really essentially slower and more sensitive than hard disk that is why it is more prone to damage (MSD, 2006). Fourth, ergodic access memory (RAM) is the primarily take over for storage of data that occurs in the computer’s memory and is stored directly at the computer’s Central Processing Unit (CPU). The two types of RAM are the SRAM and the DRAM. SRAM stands for Static RAM and the latter meaning, energising RAM (DRAM). With the use of RAM, user can program the CPU to read, write, and locate data.\r\nThe role of RAM is to carry out and bleed calculations at high speed which is do possible by the said feature of RAM or computer memory that operates random to locate items or applications in the computer system (MC, 2008). Fifth, with the use of load down disks, the compact disc read-only memory operates and exemplifies the use of read-only memory for share and sending applications like music files, games, and another(prenominal)(a) multimedia files and desktop applications. The capacity of CD-ROM when it comes to data storage is up to 650 M.\r\nRecently, CD-ROMs tip to be much cheaper than other storage devices. CD-ROM is appropriate for expansion of one’s personalized computer system. In addition, CD-ROM does not play a role in determining the speed of a computer. In fact, user retrieves data slower than any other useable data computer storage device in the market if the computer is not supported by CD-ROM’s â€Å"data transfer speed (MSD, 2006). ” Sixth, attach is a thin strip of plastic, magnetic coated device used mainly for recording and it is known to be appropriate for secondary data storage or backup.\r\nMoreover, this tape is most appropriate for the purpose of calculations or â€Å"personal computing. ” There is a no role that a tape plays in order to determine speed in a particular computer; further, data access is slower than evaluate together with its inconvenience for the required recovery of data in orderly and chronological manner (MSD, 2006). Lastly, clock speedâ€as measured in megahertz (MHz), is the â€Å"speed of the internal clock of microprocessor. ” Clock speed is appropriate for functioning in surgical operation in the internal processing of a computer.\r\nThe clock speed plays an important role in determining the speed of a computer and it affects the overall performance of the computer (MSD, 2006). Conclusion Several types of hardware storage devices are invented for data storage in computers: the hard disk, floppy disk, RAM, CD ROM, and tape. in all mediums except for the floppy disks, CD-ROM, and tape play a role in determining the speed of a computer. These devices except for the other three are hardware components that determine the speed and performance of a computer.\r\n'
