Video Card free essay sample

Video Card is an expansion card whose function is to generate and output images to a display. Many video cards offer added functions, such as accelerated rendering of 3D scenes and 2D graphics, video capture, TV-tuner adapter, MPEG-2/MPEG-4 decoding, FireWire, light pen, TV output, or the ability to connect multiple monitors (multi-monitor). Other modern high performance video cards are used for more graphically demanding purposes, such as PC games. RAM (random access memory) is the place in a computer where the operating system, application programs, and data in current use are kept so that they can be quickly reached by the computers processor. RAM is much faster to read from and write to than the other kinds of storage in a computer, the hard disk, floppy disk, and CD-ROM. However, the data in RAM stays there only as long as your computer is running. When you turn the computer off, RAM loses its data.

LAN Card A network interface card (NIC) is a computer circuit board or card that is installed in a computer so that it can be connected to a network. Personal computers and workstations on a local area network (LAN) typically contain a network interface card specifically designed for the LAN transmission technology, such as Ethernet or Token Ring. Network interface cards provide a dedicated, full-time connection to a network. Most home and portable computers connect to the Internet through as-needed dial-up connection. The modem provides the connection interface to the Internet service provider. Northbridge is an Intel chipset that communicates with the computer processor and controls interaction with memory, the Peripheral Component Interconnect (PCI) bus, Level 2 cache, and all Accelerated Graphics Port (AGP) activities. Northbridge communicates with the processor using the front side bus (FSB). Northbridge is one part of a two-part chipset called Northbridge/Southbridge. Southbridge handles the input/output (I/O) functions of the chipset. The Intel Hub Architecture (IHA) has replaced the Northbridge/Southbridge chipset. The IHA chipset also has two parts: the Graphics and AGP Memory Controller Hub (GMCH) and the I/O Controller Hub (ICH). The IHA architecture is used in Intels 800 series chipsets, which is the first chipset architecture to move away from the Northbridge/Southbridge design. Southbridge is an Intel chipset that manages the basic forms of input/output ( I/O ) such as Universal Serial Bus ( USB ), serial , audio, Integrated Drive Electronics ( IDE ), and Industry Standard Architecture ( ISA ) I/O in a computer. Southbridge is one of two chipsets that are collectively called Northbridge /Southbridge. Northbridge controls the processor , memory , Peripheral Component Interconnect ( PCI ) bus , Level 2 cache , and all Accelerated Graphics Port ( AGP ) activities. Unlike Northbridge, Southbridge consists of one chip, which sits on Northbridges PCI bus. The Intel Hub Architecture (IHA) has replaced the Northbridge/Southbridge chipset. The IHA chipset has two parts also, the Graphics and AGP Memory Controller Hub (GMCH) and the I/O Controller Hub (ICH). The IHA architecture is used in Intels 800 series chipsets, which is the first chipset architecture to move away from the Northbridge/Southbridge design. CMOS – it is a battery that is responsible for the time and date of the computer even if it is turned off. And it is used for the initial power source of the CPU when you turn it on. Processor
