ROM is an acronym for Read-Only Memory. Once data has been written onto a ROM chip, it cannot be removed and can only be read. RAM is an acronym for Random Access Memory. Specific contents can be read or written directly by the CPU in a very short time, regardless of the order in which they were recorded.
2 things to answer that Your question sounds like a test. RAM and ROM are two different things, RAM is the amount of virtual memory a computer has and ROM is read only material.
If I was to purchase a computer that is a average desktop computer how much RAM and Rom should I have?
RAM is an acronym for Random Access Memory; ROM is an acronym for Read Only Memory. Both RAM and ROM are random access; that is, each cell in memory is directly accessible. The cells in RAM can be both read from and written to. The cells in ROM can only be read from. The bit pattern in ROM is determined at the time of manufacture or burned when the computer is assembled. Once a ROM has been burned (written), it cannot be changed. Another major difference is that RAM is volatile and ROM is not. This means that RAM does not maintain its bit patterns when the power is turned off, but ROM does.
RAM
In any computer built in the last 25 years there are 3 types of memory inside the computer. Read Only Memory, Random Access Memory and the Hard Disk. When the computer starts up it first runs a self check from information stored in the ROM. When everything that should work is working then the start up loads the Operating System from the Hard Disk into RAM. The OS then loads all relevant applications into RAM and takes you to the desktop. Deliberately no particular OS has been mentioned because it is the same for all. In all, Yes, RAM and ROM are both internal memories of a computer.
The computer is pulling from the hard drive information and is putting into RAM by using software that is burned into the ROM.
Ram Rom PROM
ROM isn't erased when you turn the power off, whereas RAM is.
ROM
D-Ram. It's a car, smartass.
When purchasing a computer, you need only be concerned with the RAM. All computers have ROM, but for the most part, the type or amount of it will make no impact on any aspect of the computer's operation. Since no applications you run are going to rely on ROM for storage, that leaves only RAM.
ROM is burned with a ROM/PROM burner (small computer with pin outs for a lot of IC's) - RAM is filled by the motherboard/memory controller on a mainboard.
ROM is memory the computer will remember. RAM is memory the computer will loss when you turn off the computer.
