P1 Page 2 Primary storage Secondary storage Tertiary Storage Peripherals Backing storage Portable and fixed drives Peripherals Peripherals fall into two groups. Which are: Output devices such as a monitor, printer or plotter present the results of any processing to the user. Input devices such as a keyboard, camera or scanner provide a way for the user to put data into the processor and to give commands (e.g. a pointing device like a mouse to click on the application you want to open, or to select an option from a menu). According to their type (serial or parallel), input and output devices need to be connected to the processor using appropriate cabling (e.g. coaxial, optical, twisted pair) to an appropriate port; or configured as wireless devices. Backing storage There are three types of backing storage which are Primary storage, Secondary storage and Tertiary storage. Primary Storage The primary storage is located within the computer, is relatively small and the majority of it is lost when the computer is switched off. Secondary Storage secondary storage device or backing store is needed, such as a hard drive Solid-state drive SD card DVD Tape drive USB thumb drive CD Floppy diskette Hard drive Tertiary Storage secondary storage device or backing store is needed, such as a hard drive Primary storage Secondary storage Tertiary Storage Portable and fixed drives In the design of early computers, the drives (i.e. the readers) were located within the casing. Hard disks were fixed within the casing but other media formats (such as magnetic tape and floppy disks) provided portable ways of storing data. More recently, external hard drives have been developed and this has brought with it the option to move a hard drive (and the hard disk within it) from one computer to another. Similarly, pen drives and card readers, both of which plug into the USB port, provide a portable solution to data storage. With the increased capacity and compact format of these devices, it is now possible to enjoy portability for large amounts of data.

P1 Page 3 Performance factors Performance factors When deciding what storage device to use, a number of factors need to be taken into account. How much data will the device hold? What is its maximum capacity? How fast can the data be stored on (written to) the device? How fast can the data be retrieved (read) from the device?The performance of a system can be monitored using a profiler.

P3 explain the purpose of different software utilities Page title Explan the Purpose of different software utilities Virus protection Firewalls Cleanup tools Drive formatting What is the purpose of different software utilities Software utilities offer security in the form of virus protection and firewalls Virus protection Anti virus software is used to detect, prevent and remove malware, it can also prevent computer viruses, computer worm, Trojan horses, spy-ware and ad ware. Anti virus software can also impair a computers performance. Button Firewalls Firewalls build a protective barrier around computers that are connected to a network, so that only authorised programs can access data on a particular workstation. The user can control exactly which software is allowed to pass data in and out of the system. For example, automatic updates might be allowed for some installed software. Button Cleanup tools Over a period of time, a PC becomes cluttered with data that you do not need. Removal of cookies: Each time you visit a new website and register so that you can receive newsletter updates or make a purchase, a cookie is most likely left on your PC so that the site can recognise you the next time you visit. Internet history: Each time you request a page on the Internet, a copy of that page is retained in the Temporary Internet Files folder. Defragmentation: Each time you save a file, the space on your hard disk begins to fill. When files are deleted, some space becomes available, which appears as ‘gaps’ on the map of the disk. Button Drive formatting For storage media to be recognised by your computer so that it can be used to store data files, it has to be initialised or ‘formatted’. Physical (low-level) formatting tests the surface, scanning for imperfections and setting aside those sectors that cannot be used. Logical (high-level) formatting prepares the disk by setting up a file system which then defines how files and folders will be stored and accessed. Button

Il s'agit d'une interface de bus informatique permettant de connecter des adaptateurs de bus hôte à des périphériques de stockage de masse tels que des disques durs et des lecteurs optiques. IDE signifie Integrated Drive Electronics. Il fait référence à une interface électronique standard entre les chemins de données (ou bus) d'une carte mère d'ordinateur et les périphériques de stockage sur disque de l'ordinateur, basée sur la norme de bus 16 bits IBM PC ISA (architecture standard de l'industrie). EIDE signifie Enhanced Integrated Drive Electronics. tandis que EIDE supportait un débit allant jusqu'à 16,6 Mbps. Cependant, certaines sources indiquent que la vitesse de transfert est environ quatre fois plus rapide en moyenne. Le maître est un modèle de communication pour les périphériques matériels où un périphérique a un contrôle unidirectionnel sur un ou plusieurs périphériques.
