Storage Devices

ASSIGNMENT#1 ICT PC-WAQAR AHMED BESE-17 A Submitted to: Lec. Bilal Rauf transshipment center Devices severe disk(HDD) unsaid Disk is a non-volatile, random access, magnetic repositing device used in the computers. These were introduced by IBM in 1956. primary(prenominal) purpose of Hard Drive(HDD) is to line of descent data. HDD stores data by the do by of magnetic recording. Major Components * Coer * Platters * Head * indicant number Connector * IDE Connector * Jumper Block * Actuator * Spindle A typical HDD has two electrical motors: * book motor that spins the discs. * Actuator that positions the acquire/write head on the disc. charismatic Recording HDD stores data by magnetizing ferromagnetic literals directionally. The data be read from the disk by detecting the transitions in magnetic field strength and decode the originally write data. There atomic number 18 unlike encode processes, such as: * Modified Frequency Modulation * crowd tag Recording * Run-length Limited convert A Cobalt base intermixture is used as magnetizing secular. HDD consists of a spindle which holds the platters. Platters are non-magnetic material and hold preserve data.

Platters are usually do of aluminum glass or ceramics. The Platters are spun at genuinely exalted speeds(15000RPM). Data is indite to, and read from platter as it rotates previous(prenominal) devices called read-write heads. Read write heads scarper very close oer the magnetic surface. It detects and modifies the magnetic material under it. Data is stored on this magnetic material i-e disc. The cipher gives microscopic view of platters. Capacity computer memory cognitive content of HDD is increasing day by day. Nowadays HDDs digest a storage capacity of more than 1000 GB = 1 Terabyte. External Hard Drives External HDDs can be detached from computers and can channelise as USBs. They work resembling as ordinary unenviable drives. It can store data, wanton away a backup, bootable, disk cloning, data formatting and all other ordinary...If you respect to get a blanket(a) essay, order it on our website: Ordercustompaper.com
