Essential Interview Questions For Systems Software Engineer
1. Explain the concept of virtual memory in detail.
Virtual memory is a technique that allows a computer to access more memory than it actually has. It does this by using a portion of the hard drive as a temporary storage area for data that is not currently being used. When the computer needs to access data that is stored in virtual memory, it copies the data into RAM. This process is transparent to the user, and it allows the computer to run more programs and processes than it would be able to if it only had physical RAM.
