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.
What else can I help you with?
Is PROM a primary storage device?
yes
Is PROM a secondary device?
no prom is primary device
Is ROM a storage device?
ROM = Read Only Memory This is a permanent storage device, usually a chip or an optical disk. Depending on the device, it is written to once, and then is read-only There are some variations, including PROM (Programmable Read Only Memory) and EPROM (Erasable Programmable read only memory)

What are examples of primary memory?
examples of primary memory are RAM, ROM, PROM, EPROM , etc.....
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.
What is the alliteration for prom?
Alliteration for "prom" could include phrases like "prom night" or "perfect prom." This literary device emphasizes the repetition of the initial consonant sound, creating a catchy and memorable effect. Other examples might include "prom parade" or "promposal party."
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 boot PROM?
Boot PROM (Programmable Read-Only Memory) is a type of non-volatile memory used in computers and embedded systems to store the firmware or bootloader code that initializes hardware during the startup process. When a device is powered on, the boot PROM provides the necessary instructions to load the operating system or further software from secondary storage. Unlike regular ROM, some boot PROMs can be programmed or reprogrammed, allowing for updates or customization of the boot process. This ensures that the system can reliably start up with the correct configurations and settings.
