A motherboard is a type of computer system board that contains the majority of the components required to support a computer system, such as the CPU, memory, chipset and ports.
The memory slots on a motherboard are typically identified by the type of memory they can support. For example, a motherboard may have two DDR4 memory slots that can support both DDR4 and DDR3 memory modules.
A computer’s memory is important for storing data such as passwords and other confidential information. If the computer’s memory is damaged, the data stored in it may be compromised.
To protect against this, motherboard manufacturers typically include multiple memory slots on their boards so that customers can replace damaged or missing memory without having to replace the entire computer system.
