    All about internat computer replacement in one place

What is the motherboard and what is it for?

The motherboard or as it is called in some countries the motherboard or motherboard is the most important part of the CPU (Central Processing Unit), it is a very complex circuit that is responsible for joining all the components that are needed to process the information that the computer receives.

The microprocessor, RAM and hard disk are installed on the motherboard, which are basically the three elements needed for a CPU to become a computer. In the first one, the information is received and processed, the second is in charge of giving the support so that the processes are executed 100% and in the third one the information is stored to later provide the results.

The motherboard BIOS is a special chip that saves initial configuration of the computer.

The internal parts of the motherboard are: BIOS, chipset, battery, cache, electrical connector, ZIF socket, DIMM slots, SIMM slots, PCI slots, AGP slot, ISA slots, floppy connector, IDE connector, SATA connector, keyboard connector, connector keyboard, mouse connector, USB connector, RJ45 connector.

Perhaps one of the components or parts of a motherboard is the Chipset. This chip is the one that synchronizes or sends all components inside the motherboard, to call it somehow. Generally for each family of processors (Pentium 4, i7, Athlon X2) there is a special chipset that adapts all buses or memory for proper operation. Below you have a picture of the VIA VT82235 chipset:

Look at the connections the chipset has. Inside the motherboard is the most important component. You also have the battery that is used for the clock to work properly.

In the motherboard there is a bus system that is responsible for guiding the information between the CPU and its memory, currently the computer bus system is 64 bits but we can still find many 32 bits, the bus capacity is measured by the speed of the clock, that is, it can be 66Mhz, 100Mhz, 133Mhz and since the Pentium IV system went on at 400Mhz.

One of the oldest buses that has almost disappeared from the market is the 16-bit ISA (Industry Standard Architecture) bus, which uses or uses a black slot in which video, sound and modem cards could be connected. Older After the ISA, other bus systems such as the EISA (Enhanced Industry Standard Architecture), MCA (Micro Channel Architecture) and VLB (Video Local Bus) were created, which have also disappeared.

In the current motherboards the bus system known as PCI (Peripheral Component Interconnect) is used, although as we can see recently, some motherboards are already disappearing using PCI slots and replacing them by increasing the inputs via USB.

Like the ISA bus, another component of the motherboard that has disappeared completely is the SIMM type slots since the memories that were placed there were outdated for quite some time.

Motherboard socket

We cannot forget the socket or the place where the processor goes. Each family of processors has a socket since the architecture changes with each family of processors. It is also here where the heatsink with the fan goes since it is the part that heats up the most.
