Given a direct-mapped cache of size 8 KB with a block size of 16 bytes, calculate the number of lines in the cache.
Use the formula of total size divided by block size.
An address 2048 needs to be accessed from a direct-mapped cache with 256 lines and a block size of 32 bytes. Determine the cache line where this address maps.
Don't forget to consider modular operations while calculating the line number.
