Cache memory is a high-speed memory component that ensures users can efficiently retrieve frequently accessed data from the computer’s memory. It acts as a temporary storage space, usually in a chip form, and enables professionals to access memory more quickly than if they used the computer’s main hard drive.
A motherboard is the biggest circuit board in a computer that serves as a hub for a computer’s components, such as the CPU, RAM, storage devices, and peripheral devices.
A chipset component integrates into the motherboard and manages the data flow from the processor to the memory and the peripherals. Candidates should know that chipset timing affects the system’s performance.
No IT professional is perfect, and it’s normal for them to make some errors in their role.
