Explain the differences between Paging and segmentation.
Paging and segmentation
Paging
Segmentation
Computer memory is separated into small partitions which are all similar size and considered to as, page frames. Then while a process is loaded this gets divided in pages that are similar size as those earlier frames. The process pages are after that loaded in the frames.
Memory-management scheme which supports user vision of memory.
Computer memory is allocated in different sizes (as segments) depending upon the required for address space through the process.
Address generated through CPU is divided into:
Page number (p) - It used like an index in a page table that contains base address of each page into physical memory.
Page offset (d) - It combined with base address to describe the physical memory address which is sent to the
memory unit.
Logical address contains a two tuple:
< segment-number, offset >
Transparent to programmer (i.e. system
allocates memory)
Includes programmer (i.e. allocates memory to
specific function inside code)

Define miss penalty? The extra time required to bring the desired information into the cache is known as miss penalty.
How would you kill a process? The "kill" command takes the PID as one argument; this signifies which process to terminate. The PID of a process can be got using "ps" command
