System Unit

Expansion Card :
Electronic board that is inserted into an expansion slot of a computer motherboard to add additional functions that is not available an a motherboard such as graphic cards like nVidia GeForce Graphics Accelerator, sound card, and network card. Motherboards offers only basic functions while the expansion card add on further functions to the system unit.



Network Interface Card :
Network Interface Card (NIC) is a device used by a user to connect his computer to other computer through a Local Area Network (LAN) connection. The commom protocols used by the LAN is Ethernet. NIC must be installed in each computer device to receive connection from the existing LAN connections in order to accesss the internet.


Cache Memory :
A Cache Memory is a device which stores instructions to store memory that is repeatedly required to run programs, thus improving overall speed. Cache Memory allows the CPU to transfer data to system bus according to the motherboard capability. This will avoid jam which might occur during the transfering of the file.


Plug & Play :
Plug & Play (PNP) is a capability developed by Microsoft or other creators of Operating Systems to recognize a device plugged into a USB port without actually having to install it. Device like mouse and keyboard are two examples of PNP device. They are not required to be installed on the system for the user to use it.


Sockets :
Sockets are the built-in devices on motherboards that accept various hardware components in a single connection between two network application. Computer sockets were referred to as Integrated Drive Electronics (IDE) slots, followed by Enhanced IDE (EIDE) slots. Nowadays motherboads is made with lots of sockets in them to reduce the need for numerous hardware installed on the computer.

Chips :
Chips are a small semiconducting material usually composed of silicons on which an integrated circuits is embedded. A computer chip contains millions of transistors on electronic boards called printed circuit boards to transmit data signals. A few examples of a computer chip is microprocessors and memory chips.


Slots :
Slots refers to an opening on a motherboard where a circuit board can be inserted to add new capabilities to a computer. The boards inserted into a slot are called expansion boards, expansion cards, and add-ons. Expansion slots for PCs come in two basic sizes: half- and full-size. Half-size slots are also called 8-bit slots because they can transfer 8 bits at a time. Full-size slots are sometimes called 16-bit slots. In addition, modern PCs include PCI slots for expansion boards that connect directly to the PCI bus.

Buslines :
Bus is a subsystem that transfers data between computer components inside a computer or between computers. The bus lines also link the CPU to different parts on the system board of your computer. The data flows in the form of bits along the bus lines. There are several types of bus lines, some of which are as follows, Industry Standard Architecture, the bus line capacity is 16 bit.

Serial Port :
A serial port is a serial communication physical interface through which information transfers in or out one bit at a time. Most serial ports on personal computers conform to the RS-232C or RS-422 standards. A serial port is a general-purpose interface that can be used for almost any type of device for example modems.


Parallel Port :
A parallel port is a type of interface found on computers for connecting various peripherals. It is also known as a printer port. Parellel ports are used by a computer to connect an external device such as printer.




Universal Serial Bus :
USB is an external bus that stores data and information. Up to 127 devices that can be used by a USB port such as joysticks, mouse, keyboard, and thumbdrive. USB also supports Plug & Play installation for immediate usage of the hardware.



Firewire Port :
Firewire is a high speed serial bus that supports a chain op to 63 devices at over 400Mbps. Firewire serves as the main connection between computers, digital devices and might even external hard disks.
