Address space is the total number of identifiable locations in memory. I just learned that line. What does that mean elaborately?
like it is said, a memory with 64KB and a word size of 1 byte has an address space ranging from 0 to 65535. How that came from? And why ranging? because I got two other examples saying exact adresses?
the examples are:
1) A computer has 32 MB memory. How many bits are needed to address any single byte in memory?
Solution: 25 bits
2) A computer has 128 MB memory. Each word (what is the word elaborately?) is 8 byte. how many bits are needed to address single word? (Can you please make me understand tge question and the calculation?)
Solution: 24 bits
