For example, when they say the system is ‘booting up’ I knew it meant the system is getting ready for the user to start using its applications, but how exactly is it ‘getting ready’? As days passed by, I read some books, used some development boards, read some forums and with all that my knowledge of bootloader improved to a stage...

When I began my career in Computer Science, one of the technologies that amazed me most was how the memory of computers work and how they store data. As my career progressed I was constantly being introduced to several types of memory. I had several questions in my mind such as How does memory work on computers? Why there are so many types of memory? Can’t a single memory device be used for all purposes? If ROM is read-only then how come we are able to write data to our hard disks, USB flash drives, and SSDs? If I can...
