Question

expand ..RAM,ROM,EPROM,EEPROM,PROM.​

Answer 1

The expansion is as follows:

Explanation:

1. RAM

• Random-access memory (RAM) stands for random-access memory, but what exactly does that imply?
• The RAM in your computer is simply short-term memory that stores data as the processor requires it.
• This should not be mistaken with long-term data stored on your hard disc,
• which remains accessible even after your computer has been switched off.

      2. ROM

• Read-Only Memory is abbreviated as ROM. It's a term used to describe computer memory chips that store either permanent or semi-permanent data.
• ROM, unlike RAM, is non-volatile; the contents of ROM will not be erased even if your computer is turned off.
• A little piece of ROM in almost every computer contains the boot firmware.

     3.  EPROM

• EPROM (erasable programmable read-only memory) is a type of programmable read-only memory that can be wiped and reused.
• The memory chip is erased by sending a strong UV light through a window built into the chip.

     4.EEPROM

• The user-modifiable read-only memory (ROM) EEPROM (electrically erasable programmable read-only memory) allows users to periodically erase and reprogram stored data in an application.
• ,Unlike EPROM chips, EEPROM memory does not require the computer to be removed to alter the data.

    5.PROM

• A programmed read-only memory (PROM) is a type of digital memory that allows the contents to be altered only once after the device has been manufactured.
• The data is then irreversible and cannot be altered.
• It's a particular form of read-only memory (ROM).
• In digital electronic systems, PROMs are used to store persistent data, mainly low-level programmes like firmware.
