As we know, ROM i.e. read only memory can't be altered and comes in in-built form with the computer system. The user can't make any changes. To overcome this problem PROM came into existence. PROM i.e. programmable read only memory allows the user to program their own. Once the chip is prepared again user can't edit it. But also now the technology have been so developed that now we can erase our data and it gave two type of PROM i.e. EEPROM and UVPROM which are erased through high electric pluse and with the help of UV rays respectively. Remember, there is still not the concept of editing the data.

Difference between primary and secondary memory?
Primary memory refers to the main memory that is directly accessible by the CPU, such as RAM, used for storing data and instructions currently in use by the computer. Secondary memory, like hard drives or SSDs, is used for long-term storage of data and programs even when the system is powered off. Primary memory is faster but has limited capacity, while secondary memory is slower but has greater storage capacity.
Definition of memory and its types?
Memory refers to the physical devices used to store programs (sequences of instructions) or data (e.g. program state information) on a temporary or permanent basis for use in a computer or other digital electronic device. Computer Memory is two types as Primary Memory and Secondary Memory at the base of uses. The term primary memory is used for the information in physical systems which function at high-speed (i.e. RAM), as a distinction from secondary memory, which are physical devices for program and data storage which are slow to access but offer higher memory capacity. When data of Primary Memory stored on secondary memory is called "virtual memory".Primary MemoryThe term "memory" is often (but not always) associated with addressable semiconductor memory, i.e. integrated circuits consisting of silicon-based transistors and used as primary memory. Primary storage (or main memory or internal memory), often referred to simply as memory, is the only one directly accessible to the CPU. The CPU continuously reads instructions stored there and executes them as required. Any data actively operated on is also stored there in uniform manner. RAM used for primary storage is also volatile, i.e. they lose the information when not powered). Cash Memory is also a super fast then RAM and it working for only processor.There are two main types of semiconductor memory: volatile and non-volatile.Examples of non-volatile memory are flash memory (sometimes used as secondary, sometimes primary computer memory) and ROM/PROM/EPROM/EEPROM memory (used for firmware such as boot programs). Examples of volatile memory are primary memory (typically dynamic RAM, DRAM), and fast CPU cache memory (typically static RAM, SRAM, which is fast but energy-consuming and offer lower memory capacity per area unit than DRAM).Secondary MemoryThe term "storage" is often (but not always) used in separate computers of traditional secondary memory such as tape, magnetic disks and optical discs (CD-ROM and DVD-ROM). Secondary storage (also known as external memory or auxiliary storage), differs from primary storage in that it is not directly accessible by the CPU. The computer usually uses its input/output channels to access secondary storage and transfers the desired data using intermediate area in primary storage. Secondary storage does not lose the data when the device is powered down-it is non-volatile. Hard disk, CD and DVD drives are usually used as secondary storage. Some other examples of secondary storage technologies are: flash memory (e.g. USB flash drives or keys), floppy disks, magnetic tape, paper tape, punched cards, standalone RAM disks, and Iomega Zip drives.
Prom in computer terms?
Short for programmable read-only memory, a memory chip on which data can be written only once.Once a program has been written onto a PROM, it remains there forever.Unlike RAM, PROMs retain their contents when the computer is turned off.The difference between a PROM and a ROM (read-only memory) is that a PROM is manufactured as blank memory, whereas a ROM is programmed during the manufacturing process.To write data onto a PROM chip, you need a special device called a PROM programmer or PROM burner.The process of programming a PROM is sometimes called burning the PROM.
What is meant by primary storage?
Primary storage, also known as main storage or memory , is the main area in a computer in which data is stored for quick access by the computer's processor . On today's smaller computers, especially personal computers and workstations, the term random access memory (RAM ) - or just memory - is used instead of primary or main storage, and the hard disk, diskette, CD, and DVD collectively describe secondary storage or auxiliary storage.The terms main storage and auxiliary storageoriginated in the days of the mainframe computer to distinguish the more immediately accessible data storage from storage that required input/output operations. An earlier term for main storage was core in the days when the main data storage contained ferrite cores.2) Primary storage is sometimes used to mean storage for data that is in active use in contrast to storage that is used for backup purposes. In this usage, primary storage is mainly the secondary storage referred to in meaning 1. (It should be noted that, although these two meanings conflict, the appropriate meaning is usually apparent from the context.)

What is the primary and secondary?
Primary storage refers to onboard computer memory or Random Access Memory (RAM). It is memory that can be accessed directly by the CPU hardware using a memory address to fetch and process instructions and data. It is where computer programs are held while being executed. It is where data is held while it is being processed by computer instructions computer programs are held while being executed.Computer memory includes, Computer memory includes:Volatile RAM is semiconductor memory that loses its information when power is lost or the computer is turned off.Static RAM is volatile memory that does not lose its information when the computer is turned off or loses power.Read Only Memory (ROM) is memory that has fixed information prerecorded or preset and can not be changed. ROM contains the program that is first run when a computer is turned on. On a PC it is the program that runs before control is transferred to the BIOS. It may be a semiconductor chip that can only be modified once or it can be the actual arrangement of the circuitry on a chip.Programmable Read Only Memory (PROM) is a Read Only Memory that can be changed under special circumstances. Depending on the type of PROM, you may need special equipment, or need to use special instructions to write to this kind of memory. AN example is the BIOS program on a personal computer that needs a special "flash" process to update the version of BIOS it is using.Secondary storage is the media that hold your programs and data, other than when it is being used in memory.It is normally a hard drive or disk drive (magnetic media or solid state) that is kept as part of your computer system.Disk drives are also used for off site or backup storage. They are normally mounted in protective cases and connect to the computer with a USB, Firewire, or other proprietary connection.Secondary storage also includes other media such as floppy disks, diskettes, tape on reels or in cartridges, optical media (CD, DVD) or removable solid state media (referred to as flash drives, USB drives, memory sticks, SD cards, etc.It is used to save, backup, protect and transport information from one location to another.There is an alternate opinion that the hard drive should be considered primary storage and other removable storage device should be considered secondary storage.----------Primary storage, also known as main storage is the location where most of your data is stored on your computer. EXAMPLE.... HARD diskSecondary storage, some times called auxiliary storage is used to take care of the limitation of primary storage. EXAMPLE.... CD(compect disk),DVD(digital vedio disk),SD card,Memory card e.t.c----------Primary storage in a computer: RAM or random access memory is the first stage of memory (primary), it holds things such as your operating system in the ram memory so as you boot your computer it grabs it from ram, as it would be faster than accessing your hard drive every time you boot.Secondary storage is your Hard drive, where you save information on which is accessed via your operating system.is CD a primary or a secondary storage device----------Primary storage is RAM (Random Access Memory) and cache.Secondary storage is Floppy, hard drive, CDs.The primary form of storage is the hard drive that is the default also. You can also save onto flash drives, floppies, and cds which are examples of secondary forms of storage
How is data stored into the ROM chips?
ROM is Read Only Memory. Normally, data is fabricated into the ROM chips by the semiconductor manufacturer. Special mask(s) have to be made to store this data. Besides ROM chips there are PROM chips, where P stands for Programmable. In these chips, data can be stored by the end user. EPROM is Erasable PROM. A new type of ROM is OTP ROM (One Time Programmable).
