Magnetic disks are structured into concentric circles known as tracks. The tracks are the fundamental unit in which the data is organized and written to or read from the magnetic disk. Each track can further be divided into sectors, which are the smallest unit that can be accessed on a disk.

If it has a large number of jobs, then long-term jobs will have to require a long wait. Memory management is needed in the operating system because all types of tasks are stored in the main memory. Using multiprogramming up to a larger extent can cause a heat-up issue.

Block caches or buffer caches are used to improve disk performance to handle interrupts to increase the capacity of the main memory to speed up the main memory. Reading from a disk is very slow compared to accessing (real) memory.
