CPU speed or CPU performance is measured by the completed I nstruction Cycles P er S econd (IPS). Currently, CPU speeds range from 600 megahertz (MHz or million cycles per second) to 4 gigahertz (GHz or billion cycles per second).CPU (Central Processing Unit): CPU (Central Processing Unit) Processing performance of computers is increased by using multi-core processors , which essentially is plugging two or more individual processors (called cores in this sense) into one integrated circuit . ( Eg : Intel dual core, Athlon 64 X2, …)RAM (Memory): RAM (Memory) RAM or R andom A ccess M emory It is a volatile type of memory Holds instructions for processing data, processed data, and raw data. Ram is measured by: Capacity (in Megabytes or Gigabytes) Speed (in Nanoseconds)Memory (RAM): Memory (RAM) Amount of RAM installed will determine. Which software applications will run (efficiently)? How many software applications can be open simultaneously? (multitasking ability) Types of RAM: SRAM(Static RAM) DRAM(Dynamic RAM)Storage Devices: Storage Devices Magnetic storage devices store data by magnetizing particles on a disk or tape. They have a limited life-span of 1 to 5 years, depending on the device. Optical storage devices store data as light and dark spots on the disk surface. They have an unlimited life-span.Storage Devices: Storage Devices Hard Disk Drives Capacity is measured in gigabytes (GB or billions of bytes). Typically permanently installed. Used to store operating system, application software, utilities and data. Magnetic storage device.Storage Devices: Storage Devices Other Storage Devices : CD-ROM, DVD… Floppy Disc Drive USB Flash Drive (Pen-drive or thumb-drive)Input Devices: Input Devices Input devices gather and translate data into a form the computer understands . Primary input device: Keyboard - Most common input device; used to type in commands and data. Mouse or trackball enhances user’s ability to input commands, manipulate text, images. Joystick useful in education as an adaptive or assistive input device.Input Devices: Input Devices Scanners are peripheral input devices which allow users to import: Text Graphics ImagesOutput Devices: Output Devices Monitors are the most commonly used output device. Most monitors use a bitmap display. Allows user to resize the display. Divides the screen into a matrix of tiny square “dots” called pixels . The more “dots” a screen can display, the higher the resolution of the monitor.
