There are many individual components within a computer system. Being familiar with each of these, their function, and their interdependence is critical for this job. The interviewer will ask you several questions about the internal components of hardware, software features, the functions of applications, and other questions related to the IT technology infrastructure. Since these can be the root cause of failures or issues within the systems, you need to be familiar with them. It would be best to address how you would research each component using tech manuals, vendor sites, and online resources.

"The function of cache memory is to act as a buffer between the CPU and random access memory, or RAM. It is a high-speed type of memory that provides quick access to the most frequently requested instructions and data. There are three levels of cache memory, designated as L1, L2, and L3. L1 is generally found in the processor chip. It is the smallest and the fastest for the CPU to read. It ranges from 8 to 64KB. L2 and L3 cache memories are larger than L1 and can hold more information, but these take longer to access."
