Knowledge of the CPU

A team that has several major subsystems, such as the Central Processing Unit (CPU), memory and device drivers. All these components are connected to a "bus". The bus is essentially an information highway, and all other components work together, bus.The data transmission of the current computer, the party that controls all the calculations and the treatment of other parts of the CPU "(CPU). Central Processing Unit (CPU) contains the electronic clocks, the timing of all operations, the electronic circuits that perform arithmetic operations like addition and multiplication, and circuits to identify the cause, that the instructions that control program and data memory circuits can be recovered. instructions and data are stored in main memory. The CPU is sold as necessary. device drivers to take care of peripheral input devices like keyboards and mice take work output devices such as printers and video displays and storage devices such as CPU and peripheral controllers disks.The together. to exchange information between your computer and to transmit the user Sometimes the processor is responsible for the data an input of the device by transmission controller moves through the bus and directly loaded into the CPU, the output is the same distance in the opposite direction -. the CPU the bus and by controlling an external device.

In other cases, the processor can get a device driver to transfer data directly to or from the main CPU chip on the motherboard of the computer's main memory.The. They come in different shapes, sizes and packaging. Older CPUs came in DIP format, and some 286s and 386 QSOPs principles (see IC), but what you'll find that most are from the apartment on the chip of the PGA, PGA, SPGA chips.The space used, the friction clutch is installed . Assembly and dismantling had to be done carefully to avoid bending or breaking the pins of the processor. First he had to align the chip. There is always a way to name, pin 1 on both the chip and socket. It may be a point in a corner or an arrow or a small screen '1 '. Generally, a processor with one of your shortcuts and have that the party named in the decision to align. You must make sure that all pins are straight and square on the chip, then put the chip so that all pins are inserted into each hole in the base. To install the chip, press firmly and evenly. If the legs are not quite in their holes, or if not pushed down, the markers can be bent to one side. Try to straighten the pins is not impossible, but it usually means that on. You will learn quickly, take your time and be careful. Elimination is another problem.

A cut is very narrow and has no control, while trying to get chips (we talk a lot of friction has a chip in the interview). Some packages from the update, or "Turbo" is a person lying on the trigger action was better, but still does not offer much more control. The best way is to gently insert a small screwdriver between the chip and the base without touching the pins down, and turn very easily remove the chip with a very small amount. Then go to another and do the same. Currently, work your way around the chip, due out easy.The identified problem and a group of new decision-Zero Insertion Force (ZIF) was developed. This decision makes a big difference in the removal and installation of the PGA and SPGA CPU. A small knob or lever on the side of the elevator core and unclips to solve completely pins. You can use the old CPU, you go to the other, and pull the lever down, put it in his little clip. Not bent or broken, chipped edges, without the CPU or a Pentium II and Pentium III Intel Celeron socket.For chip, the processor is a small group of external cache and use coated or packaged in a plastic cartridge.

The "Slot 1" style clip on the motherboard and CPU "slot 1" must be clear connector.As, the CPU must be connected to the motherboard. Most motherboards allow more than one type of CPU Under the model, manufacturer and influences the speed but usually accept only one type of output. This is a consideration that should be discussed and resolved before an acquisition. The motherboard manual will tell you what type of processor included in the return. If you have a manual, please visit the website of the manufacturer. Normally such information. Main CPU manufacturers, Intel, Motorola, IBM, Advanced Micro Devices (AMD) and Intel Cyrix. Evaluate the processor is done before it can be PC. Enter the first PC chips from IBM. most chips in the BIOS (Basic Input / Output System) developed in the first plates were based on an Intel. Intel is still considered the No. 1 producer and has set the standard for processors.

Other CPU manufacturers and distributors tend to compare their products with Intel, saying it is "comparable to a Pentium II-350" or "better than the PIII-500." A specific processor features described by its manufacturer, model and speed in megahertz (MHz). Advice of a computer system has a quartz crystal in this constant signal or the beat like a metronome. Each beat is called a clock cycle and is measured in megahertz, or millions of cycles per second. A processor in a multiple of the frequency of the motherboard and the instructions are executed synchronously clocked at every clock cycle the CPU. Therefore, if the processor do one instruction per cycle, and has a 500 MHz processor, the chip can execute 500 million instructions per second. Your heart will not beat too many times in life. Current technology, Intel and AMD and 1.5 GHz (gigahertz) CPU this year. There are a half million instructions per second!

The CPU is called the "brain" of the computer. Manages and directs all activities of computer users time, transmission, reception and processing. But, as the "brains" of a project or an organization depends largely on your support group and counseling. There are many factors contributing to the CPU and the speed and performance of the machine are connected. Some of these factors are: whether a math coprocessor is present and whether internally or externally.

Speed ​​up the system clock and CPU. The amount of internal cache and external cache memory. The bus architecture or support circuitry on the motherboard.
