B.Discuss the following:
1.Read-Only memory - In computers and other electronic devices, read-only memory (ROM) is a type of non-volatile memory.
After the memory device is manufactured, data saved in ROM cannot be electronically manipulated.
Read-only memory, commonly known as firmware, is useful for storing software that is rarely modified during the life of the device.
Plug-in cartridges containing ROM can be used to deploy software applications (such as video games) for programmable devices.
2.Random access memory - Random-access memory (RAM; /rm/) is a type of computer memory that can be read and changed in any order, and is commonly used to store working data and machine code.[1][2] In contrast to other direct-access data storage media (such as hard disks, CD-RWs, DVD-RWs, and the older magnetic tapes and drum memory), a random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the
3.Operating system - An operating system (OS) is software that manages computer hardware and software resources while also providing common functions to computer programs.
Time-sharing operating systems plan tasks to make the most of the system's resources, and they may also contain accounting software to track the cost of processing time, storage, printing, and other resources.
