Terminology 2

21.Touchpad
Is an input device commonly used on laptop computers. Its function as the driving cursor on the monitor, through stimulation of finger movements that touch the touchpad. With this function well, the touchpad is used instead of a mouse. From the size, usually have different sizes, but usually not more than 50 cm ². Touchpad development also continues, which is now not only as an activator of the cursor, but also has a function for scrolling and zooming a specific document.

22.Northbridge
One of the two chips in the chipset that connects the processor to system memory and AGP and PCI bus. Another is the southbridge chip.

23.Southbridge
One of the two chips on the motherboard chipset, which controls the IDE bus, USB, Plug and Play, and so forth.

24.D-Sub
Standard output ports that are used from the video card to the monitor by using the 15-pin on the connection.

25.DVI-I
One of the DVI variant cans That pass analog and digital signals. DVI connector Itself is Used in LCD monitors are very effective to reduce video noise Pls I do the conversion from digital to analog and back to digital again.

26.MP3
MPEG-1 Audio Layer 3, or better known as MP3 is a file format that has compression encoding sound good (although lossy) so that the file size can be smaller. This file was developed by a German engineer Karlheinz Brandenburg. MP3 encoding uses Pulse Code Modulation (PCM). MP3 reduces the number of bits of data by using a psychoacoustic model (eliminating the human voice is not audible.)

27.MPEG
MPEG (Motion Picture Expert Group) is the name of the international organization ISO / IEC are developing moving image coding standard (such as video). Some of the standards developed are MPEG-2 and MPEG-3.

28.PCMCIA
Short for Personal Computer Memory Card International Association, is an organization consisting of more than 500 companies, which has developed a standard for small-sized components. Less is more for credit cards, and so-called PC Cards. Where the use of majority for notebook computers.

29.Pin
Are the grooves and the legs of the chipset that connects the module output or input data transfer and flow into the motherboard. Usually there is a row of pins on a PCB board inside a memory chip is also a slang term for these types of memory. For example, the number of pin DDR1 memory will not be equal to the number of pin DDR2 memory.

30.USB 2.0
Interface that is used most recent UFD. In theory connection with this interface capable of transferring data as fast as 480 Mbps.

31.Pitch
Pitch or also called the dot pitch, is the distance between pixel and next pixel. The greater the distance, the resulting display tends to look coarse (grainy).


32.Resolution
Describing the number of pixels that appear in the calculation of two dimensi.Sebagai example 1.280 x 1.024 pixel resolution, meaning that pixel is displayed as many as 1024 rows and 1280 columns.

33.SVGA
Abbreviations of supervideo graphics array, displaying in a resolution of 800x600 pixels.

34.VGA
Abbreviation of video graphics array, displaying in a resolution of 640x480 pixels.

35.Heatsink
Heatsink is an object which is placed on components, with the aim of releasing heat generated corresponding components. Heat transfer can go through the process of conduction, convection or radiation. On the PC components, usually the material used to heatsink is copper or alumunim. Aluminum is lighter and cheaper. While copper has the ability to release heat faster. To speed cooling, usually combined with a heatsink fan (HSF).

36.HSF (Heat Sink Fan)
A CPU components that are used to absorb heat. Usually made of aluminum. Use as the absorber temperature fan is used to improve the stability of your computer.

37.802.11a
Standard wireless network with a maximum data transfer rate of 54 Mbps and works at a frequency of 5 GHz.

38.802.11b
Standard wireless network with a maximum data transfer rate of 11 Mbps and works at a frequency of 2.4 GHz.

39.802.11g
Standard wireless network with a maximum data transfer rate of 54 Mbps (typical 200 Mbps) and works at a frequency of 2.4 GHz, with backward compatibility to 802.11b berperangkat.

40.802.11n
Standard wireless network with a maximum data transfer rate of 600 Mbps and works at a frequency of 2.4 GHz or 5 GHz. Standard 802.11n specification is expected to be finalized in 2009.
