2. There are different types of
Internal Components
Processor
Storage Devices
Memory
Input and Output Devices
Adapter Cards
3. Processor
Central Processing Unit (CPU) the heart of the computer, it is the component in a digital
computer capable of executing a program. The speed of the CPU is measure in megahertz. A
1MHz CPU can be one million CPU cycles in one second. The CPU is 32 bit and measured in MpZ.
4. Adapter Cards
There a different types of adapter cards such as: PCI, PCIe and PCMCIA.
Peripheral Component Interconnect (PCI/PCIe) is a connection interface for attaching computer
peripherals to a PC's 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 500
companies that has developed a standard for small, credit card-sized devices, this is called PC
Cards.
Processor Communication is a Hardware-based service processors, also known as management
processors, work with hardware instrumentation and systems management software and are
important for problem notification and resolution
5. Memory
There 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 be
accessed by the CPU. Read Only Memory (ROM) is a data that has been pre-recorded. Once data
has 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 contents
until it is fixed to ultraviolet light. The ultraviolet light clears its contents, making it possible to
reprogram the memory.
Flash Memory is a computer memory chip that stores information without a power source. It is
often used in portable electronics, such as music devices, smartphones and digital cameras.
6. Storage Devices
Storage 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 Disks
and FireWire Disk Drives.
7. Hard Ware - Formatting and Partition
1) You should end up in the MS DOS prompt 2) Choose "Y" to enable large disk 3) From the menu, choose option 1
A: (A drive). From A: command prompt support. You will now be presented with - Create DOS partition or Logical
type fdisk. You will be presented with the FDISK main menu as shown below. DOS drive. Another menu will
following message: present the following options.
Choose option 1 - Create primary DOS Partition. FDISK verifies the integrity of your drive and will
ask you if want to use the maximum available size of your hard disk to create the primary partition
and set it active.
8. Input Devices
Some examples of Input Devices are: Touch Screen, Graphic Tablet, Games Controller,
Microphone, Keyboard and Mouse
9. Output Devices
• Some sort of Output Devices are: Printer, monitor and Speakers.
12. There are different types of External
Components (output devices) such
as…
Scanner
Monitors
Speakers
Audio Card
13. What is an Output Device?
All those Components are Output Devices. An output device receives information from the
computer and translates it from machine language to a form that we can read or so that another
machine can read the information.
14. Monitor
A computer monitor, also known as computer screen, is a computer device that shows moving or
still 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 the
computer monitor
15. Speaker
A 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 to
listen to Films
16. Audio Card
The sound card is an expansion card that allows the computer to send audio information to an
audio device like speakers or a pair of headphones.
17. Scannaer
A scanner is a device that captures images for prints, posters, magazine pages, and similar
sources for computer editing and display. Scanners come in hand-held, and flatbed types and for
scanning black-and-white only or colour
