Computer components and functions

A. 1. PC CardExpansion cards are typically used in notebooks, so the notebook has new functions such as WLAN, Bluetooth, Sound, and others. PC Card is divided into three types. Type I, Type II and Type III. The difference in shape between the three, only the thickness is at the level of each card. Type I, which has a thickness of 3.3 mm is usually used as a memory card. Type II with a thickness of 5 mm is usually used for devices that serve as I / O such as modem, LAN, and lainlainnya. For Type III, with a thickness of 10.5 mm is usually used for devices such as micro drives or other components which have a thickness dimension.

   A. f. HDRHigh Dynamic Range lighting renderring is a procedure designed to emulate how levellevel light varies in the real world for a wide range of areas. This is usually obtained by using the data for the fl oating-point textures and targets that will be rendered also include the use of appropriate lighting algorithm. Despite offering a more interesting visual effect, but to enable this effect has a considerable performance hit for most VGA.

Unit of a GPU, the site of information transfer and processing pixel. Where, the more pixel pipelines, so the more the number of pixels that can be processed by the GPU.

   A. i. Vertex Processor
Vertex pipeline vertex processor or unit is one of the GPU that serves as a carrier of information geometry (in the form of vector points), or also directly process them if necessary. Processing itself can be in the form of fixed function (the DirectX 7.0 down), or in the form of hard-wired with the vertex shader function (up to the latest DirectX 8.0).

   A. 6. RAM
         A. a. Access Time, Timing
A measurement of time in nanoseconds (ns) are used to indicate the speed of a memory Access Time is specified, the first time in the start time CPU sends data to a memory request to the CPU receives the data requested.

   A. b. Bandwidth
A maximum capacity to move data in an electronic network, such as Bus or Channel. More in short, that is the maximum amount of data that can be moved in within a certain time unit. Bandwidth is usually expressed in units of bits, bytes, or Hertz.

   A. c. Bank SchemaA large set of configuration memory in the form of diagrams. System of the Bank Schema consists of rows (rows) and columns (fields) that describe the memory sockets within a computer system. Where, rows indicate the different sockets and columns indicate the number of banks that exist in each socket.

   A. d. Buffered
Buffered means adding this additional logic components, or the drivers into a SIMM or DIMM to increase the output current. This is done to avoid a reduction in signal quality of data resulting from the capacitance. Memory modules which include the type of "buffered", usually have small buffer chipchip mounted inside the module.

   A. e. Burst ModeIs a technique of continuous data transfer, which automatically generates a data block (in the form of an unbroken line of address / serial), for each time the processor requests data from one memory address. By assumption, the data that existed at the next address will be shaped by the sequential data in the previous address. This technique can be implemented to read and write operations.

   A. f. CAS
(Column Address Select / Strobe) is a control pin that is on a DRAM chip that is used to select and activate the column addresses in memory. A selected column in the DRAM, the data are determined by the address pins when CAS becomes active.

   A. g. CAS Latency
A delay or time delay of a memory speed when transferring data to the CPU. Thus, the smaller the latency values ​​are used, indicating a higher-speed memory that is faster response and greater transfer rate. Latency 2 memory with generally better quality than the Latency 3.

   A. h. Chipset Module
There is a row of chips on the memory chip. Usually a single chip capacity in the memory depends on how much data capacity can be accommodated on a chipset chipset multiplied by how many pieces of the complete chip memory.
