Process Equipment

Process Equipment is a CPU (Central Processing Unit) which is the main and most important unit processes in the computer that controls the entire process from data processing equipment to read data from input, process or process until the release of information (output) to the output equipment. CPU consists of three functional sections:
1. ALU (Arithmetic Logical Unit) function does all processes that require mathematical calculations and logical comparisons
2. CU (Control Unit) functions to control all other equipment.
3. Function registers store data to be processed in the ALU.
Some existing equipment within the CPU include:
• Mainboard
• Processor

Memory

Mainboard

Mainboard is one of the devices in a computer that is used as a place to install or put some other equipment such as: processor, memory, data cables (interface) hard disk, flopy disks, Card (card) crate: VGA Cards, NICs (network cards) and so forth.
Mainboard types include: Starting from the class of AT 486, Pentium I, Pentium II, Pentium III to Pentium 4 class.
Some brands such Mainboard: ECS, ASUS, U.S. Rack, etc.

Processor

Processor is a processor chip which is the brain and central control various other devices so that the computer can work with each other. Processor size is MHz (Mega Hertz) that is a matter of speed in processing data / information
Some types of processors:
• Processor Pentum I 75 MHz - 200 MHz etc ...
• Pentium II 300 MHz - 450 MHz, etc. ..
• Pentium III 650 MHz - 950 MHz and so on.
• Pentium 4 Processor GMHz 1.3 - 3.0 GHz ff.
Brand processor include: INTEL, AMD. IBM etc.
Memory
Memory is where store data or instructions. The larger memory capacities in providing the greater the data or instructions that can be accommodated to be processed.
Some Types of Memory include: ROM, RAM, EDORAM, SDRAM, DDRAM, RDRAM, etc.
Commonly used memory capacity ranging from: 16 MB 32 MB, 54 MB, 256 MB 512 MB, 1 GB, etc.
Brand-brand memory on the market: Genes V, Visipro, Kingston etc.
