The motherboard is responsible for interconnecting and providing physical support to all the internal devices of your computer.
Its importance lies in the fact that depending on which one you choose, you will be delimiting the capacity of the team. It depends on all others, such as the amount of RAM, and the type you can use, the number of USB ports or the number of hard drives.
The hard disk is the store of all the information that your PC contains. You need, therefore, a connection that serves as a transport and to that data. Usually, there are both older and older SATA IDE connectors. Some motherboards include external SATA connectors to speed up access to hard drives connected to them.
RAM exists into connectors known as memory slots. Regular plates usually have between two and four of these elements. The maximum amount of memory you can install depends on its number. Always keep in mind that you will need at least one free to add more memory to the device in the future.
The socket is the place where the processor is placed. So this delimits you precisely which ones you can use.
The BIOS is responsible for executing the program that starts your PC. It is, therefore, very associated with the motherboard since many of its features depend on this element. Sometimes it is necessary to update it to adapt the motherboard to new processors or because manufacturers discover failures.
It is where you will place the expansion cards. For example, your graphics card will need one.
The chipset is the set of circuits that interconnect the elements of the motherboard.
They all depend on the motherboard manufacturer to include them.
No. You will need a different plate for each brand of a microprocessor. Even within the same brand, you will have different types of plates for different generations of processors.
When buying a motherboard, you will see that many prices are depending on the features they offer, but this is not an element that determines, in principle at least, the benefits of one team or another.
However, in the case of using advanced features, such as overclocking, investing in a better board will make the difference.
