Computer and Information Technology part -4

Celeron, Pentium, and Core are the series of computer processors.

ROM means Read-only memory. Once data has been written onto a ROM chip, it cannot be removed and can only be read. Unlike main memory RAM (Random-access memory), ROM retains its contents even when the computer is turned off. ROM is referred to as being non-volatile, whereas RAM is volatile.

ROM is considered as the permanent memory of a computer. Data or information in ROM is not destroyed or erased even after the computer is turned off.

A means of specifying location of data in memory is called address. Think of computer memory as a series of numbered storage boxes. Each box has a unique address that allows the central processing unit (CPU) to find and retrieve the data stored in that specific location. Therefore, the address is the key to pinpointing where data resides in the computer's memory.

CD-ROM (Compact Disc Read-Only memory) is a type of optical disc. Normally CD-ROMs are already mounted and cannot be erased and filled with new data. The CD-ROMs can hold up to 700 MB data.

RAM is an acronym for random-access memory. It is considered as temporary memory and works only when the computer is functioning. Once the computer is switched off, all the data stored in RAM are lost or erased.

Random Access Memory (RAM) is the hardware in a computing device that provides temporary storage for the operating system (OS), software programs, and any other data in current use so they're quickly available to the device's processor. Random access memory is considered part of a computer's primary memory. It is much faster to read from and write to than secondary storage, such as hard disk drives (HDDs), solid-state drives (SSDs), or optical drives. However, RAM is volatile; it retains data only as long as the computer is on. If power is lost, so is the data. When the computer is rebooted, the OS and other files must be reloaded into RAM, usually from an HDD or SSD. Hence, the statement of option (b) is not true about RAM.

Solid State Drive, Hard Disk, and USB Pen Drive are types of a computer's external or secondary memory, while Random Access Memory (RAM) is part of a computer's internal or primary memory.
