RAM (Random Access Memory)
For new computers it can be both.
Yes, that is how computers used to run, it is called D.O.S.. but it will not give you any fancy video, that's for sure
Not ROM - RAM... Increasing the amount of RAM (Random Access Memory) gives the computer more 'workspace' to use - speeding up operations.
The computer uses microchips for primary and secondary memory. Virtual memory uses a portion of the computers hard drive. The former have faster access times than the latter.
By "main memory" I assume you mean Primary Storage. This would be your RAM (Randon Access Memory)
A: They are called RAM or Random access memory
RAM (Random Access Memory) or working memory
Memory is a loose term when it comes to computers. Memory can mean one of two things that are both primary and absolutely necessary to run a computer. One is RAM, which is the smaller memory that helps with computer performance. Without it, the computer will not start up at all because the RAM is used for essential backround tasks. The other memory is HDD memory (hard drives). This memory is used to store information that does not need to be accessed instantaneously. HDD memory is used to store the operating system of a computer, as well as other information such as programs and documents. There is no "primary" memory, in a computer, as it can mean two different things that are both invaluable.
The memory that the computer processor accesses directly is primary memory. It is wired directly to the processor. RAM is primary memory on a computer.
