  1. 1. Internal Components Technical Audience
  2. 2. There are different types of Internal ComponentsProcessor Storage DevicesMemory Input and Output DevicesAdapter Cards
  3. 3. ProcessorCentral Processing Unit (CPU) the heart of the computer, it is the component in a digitalcomputer capable of executing a program. The speed of the CPU is measure in megahertz. A1MHz CPU can be one million CPU cycles in one second. The CPU is 32 bit and measured in MpZ.
  4. 4. Adapter CardsThere a different types of adapter cards such as: PCI, PCIe and PCMCIA.Peripheral Component Interconnect (PCI/PCIe) is a connection interface for attaching computerperipherals to a PCs motherboard or main an circuit board and PCIe is an serial links called lanes.Every lane of the PCIe is a dual link such as simultaneously receiving and transmitting.Personal Computer Memory Card International Association (PCMCIA) is a consisting of some 500companies that has developed a standard for small, credit card-sized devices, this is called PCCards.Processor Communication is a Hardware-based service processors, also known as managementprocessors, work with hardware instrumentation and systems management software and areimportant for problem notification and resolution
  5. 5. MemoryThere are different types of memory devices such as: ROM, RAM , Flash Memory and EPROM.Random Access Memory (RAM) provides space for your computer to read and write data to beaccessed by the CPU. Read Only Memory (ROM) is a data that has been pre-recorded. Once datahas been written onto a ROM chip, it cannot be removed and it can only be read.ERPROM ( Erasable Programmable Read Only Memory) is a type of memory that has its contentsuntil it is fixed to ultraviolet light. The ultraviolet light clears its contents, making it possible toreprogram the memory.Flash Memory is a computer memory chip that stores information without a power source. It isoften used in portable electronics, such as music devices, smartphones and digital cameras.
  6. 6. Storage DevicesStorage Devices is device capable of storing data. The term usually refers to mass storage devices,such as disk and tape drives.An example of Internal Storage Devices is Hard Drive and an External Device example is RAM.Some Storage Devices are: SATA (Serial Advanced Technology Attachment), PATA (Parallel ATA),SCSI (Small Computer System Interface) and SOLID STATE.The different Hard Ware Devices are: ATA Disk Drives, Parallel (Ultra) ATA Disks, Serial ATA Disksand FireWire Disk Drives.
  7. 7. Hard Ware - Formatting and Partition1) You should end up in the MS DOS prompt 2) Choose "Y" to enable large disk 3) From the menu, choose option 1A: (A drive). From A: command prompt support. You will now be presented with - Create DOS partition or Logicaltype fdisk. You will be presented with the FDISK main menu as shown below. DOS drive. Another menu willfollowing message: present the following options.Choose option 1 - Create primary DOS Partition. FDISK verifies the integrity of your drive and willask you if want to use the maximum available size of your hard disk to create the primary partitionand set it active.
  8. 8. Input DevicesSome examples of Input Devices are: Touch Screen, Graphic Tablet, Games Controller,Microphone, Keyboard and Mouse
  9. 9. Output Devices• Some sort of Output Devices are: Printer, monitor and Speakers.
  10. 10. Exinteral Components Non-Technical Audience
  11. 11. There are different types of External Components (output devices) such as… ScannerMonitors SpeakersAudio Card
  12. 12. What is an Output Device?All those Components are Output Devices. An output device receives information from thecomputer and translates it from machine language to a form that we can read or so that anothermachine can read the information.
  13. 13. MonitorA computer monitor, also known as computer screen, is a computer device that shows moving orstill images that have been generated by the computer by the graphics card in the computer.There are several display standards in the monitor that define how the images are viewed on thecomputer monitor
  14. 14. SpeakerA speaker is a device that connects to your computer which plays music whether its through,Windows Media Player, iTunes, YouTube or any other Music Websites. You can also use sound tolisten to Films
  15. 15. Audio CardThe sound card is an expansion card that allows the computer to send audio information to anaudio device like speakers or a pair of headphones.
  16. 16. ScannaerA scanner is a device that captures images for prints, posters, magazine pages, and similarsources for computer editing and display. Scanners come in hand-held, and flatbed types and forscanning black-and-white only or colour
