Week 10: Basic Computer Parts Computer Parts Hardware Software Inside Outside Integrated Auxilary Application System Software Software 1  HARDWARE - SOFTWARE  Hardware  Software  All the machinery  All the instructions and equipment in a that tell the computer computer system. how to perform a task 2  Hardware Hardware is the physical aspect of computer. The electronic circuitry and parts of a computer. 1. Inside 2. Outside 3. Integrated 4. Auxilary 33 Hardware: Inside The parts found inside the computer case, so you won't see them unless you open the computer: Motherboard Central Processing Unit (CPU) Random Access Memory (RAM) Power Supply Unit (PSU) Video card Hard Disk Drive (HDD) Solid-State Drive (SSD) Optical disk drive (e.g., BD/DVD/CD drive) Card reader (SD/SDHC, CF, etc.) 44 Hardware: Inside, Input & Output Interfaces Input hardware - devices that translate data into a form the computer can process Output hardware - devices that translate information processed by the computer into a form that humans can understand Input interface translates data to system unit Output interface translate processed data from system to output harware 5 Hardware: Outside Common hardware connected to the outside of a computer, although many tablets, laptops, and netbooks integrate some of these items into their housings: Monitor Keyboard Mouse Uninterruptible Power Supply (UPS) Flash drive Printer Speakers External hard drive Pen tablet 66 Hardware: Outside, Input Input: is the raw information entered into a computer from the input devices. It is the collection of letters, numbers, images etc. Keyboard, mouse, scanner, camera, light pen, joystick, touch sensitive monitor etc. 77 Hardware: Outside, Output Output: is the processed data given by computer after data processing. Output is also called as Result. We can save these results in the storage devices for the future use. Monitor, printer, speaker etc. 88 Exercise INPUT OUTPUT 99 Hardware: Integrated Pieces are now usually integrated into other devices or because they've been replaced with newer technology: Sound card Network Interface Card (NIC) Expansion card (FireWire, USB, etc.) Scanner Webcam Microphone 10 10 Hardware: Auxilary There's more computer hardware called auxiliary hardware, of which a computer might have none, or several, of some kinds: Fan (CPU, GPU, Case, etc.) Heat sink Data cable Power cable CMOS battery Daughterboard 11 11
