Processor

Central processing unit (CPU), an electronic circuit which executes computer programs, containing a processing unit and a control unit. There have been many processors on the market, running at many different speeds. The speed is measured in Megahertz or MHz. A single MHz is a calculation of 1 million cycles per second (or computer instructions). This talks in binary code, the motherboard passes these codes and translates them so that the other components can understand. 

Motherboard

 

 

In personal computers, a motherboard is the central printed circuit board in many modern computers and holds many of the crucial components of the system, providing connectors for other peripherals. The motherboard is sometimes alternatively known as the mainboard, system board. The motherboard is like the brain of a computer, everything runs through this and without one the computer wouldn’t work. The motherboard allows most of the components of a computer to communicate with each other. 

 

 

Bios

In IBM PC compatible computers, the basic input/output system (BIOS) also known as the system BIOS or ROM BIOS is a standard firmware interface. The name originated in earlier computers running CP/M and other operating systems, where the BIOS was loaded from disc rather than stored as firmware (EPROMs )Communication- operating system only needs to know how to communicate with the BIOS layer. It is up to the BIOS layer to translate the operating system commands into action by the hardware. It receives these commands when the computer boots up, but not when the computer is restarted.

Power_supply

In electronic systems, a heat sink is a passive component that cools a device by dissipating heat into the surrounding air. Heat sinks are used to cool electronic components. And fans are found inside the computer case and help prevent the various computer parts inside from overheating. Without them, components of your computer can malfunction, become damaged, or even crash.

Hard_drive_configuration_and_controllers_sata_or_ide_or_eide

 

 Hard drive configuration and controllers SATA or IDE or EIDE, One of the more confusing aspects of EIDE hard drive configuration for those new to computer building is the master/slave relationship. It's actually not very hard to understand, however. The primary EIDE connection will be labelled on the motherboard as either IDE-0 or IDE-1, depending on the mood of the person who made up the stencil. If they chose to use IDE-0 and IDE-1 for the two channels, then the primary is IDE-0. But if they are labelled IDE-1 and IDE-2, then IDE-1 is the primary. (They may also be labelled as EIDE or ATAPI, rather than IDE, on some boards. It all means the same thing.)

 

Usb_port
 

 The port in which you put the USB device, most computers having 3 or 4 USB ports, they connect to the computer by cables linked to the motherboard. A USB port is a standard cable connection interface on personal computers and consumer electronics.

 

Ram

 

 RAM works in conjunction with the central processing unit (CPU). If RAM is the temporary memory, you can think of the CPU as the brain of the computer. The CPU chip retrieves data from the RAM. The chip takes those instructions and begins to move and process data through the motherboard in the correct order to its next designated location.

 

 


Graphics-card
A graphics card is a part of a computer that translates the binary data from the CPU and turns them into pictures that you can see on your computer monitor,
A graphics card uses a motherboard to connect to a computer, which is its source of power and data. The graphics card uses one of the three interfaces - PCI (peripheral component interconnect), AGP (advanced graphics port) or PCIe (PCI express).

Printer

 

a printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper; Connects to the computer via a USB cable.

Scanner, scans an image/written piece, and puts it as a jpeg on the computer, also communicates via a USB cable.

 

Pen_drive

 

Pen drive, otherwise known as a USB (universal serial bus) stick, is a data storage device that consists of flash memory. USB flash drives are typically removable and rewritable, and physically much smaller than a floppy disk. They communicate by plugging in to the USB slots on the computer, in direct link to the motherboard due to the USB port.

 

Hard_drive

 

The hard disk drive is the main, and usually largest, data storage device in a computer. The operating system, software titles and most other files are stored in the hard disk drive. The sides of the hard drive have pre drilled, threaded holes for easy mounting in the 3.5 inch drive bay in the computer case. The hard drive is secured in pace on the motherboard, allowing easy communication to the other components also mounted on the motherboard.

 

Twisted_pair_cable

 

A type of cable that consists of two independently insulated wires twisted around one another. The use of two wires twisted together helps to reduce crosstalk and electromagnetic induction. Go directly into the components in the computer, and carry information/power to each individual part.
