First, you have to realize that there are a large range of computers, with a very large range of requirements. Also, the amount of RAM will likely change rapidly in the future.
Most "el cheapos" off the shelf of Wal-Mart have between 512 MB and 1 GB of RAM. A typical desktop sold by, say, Dell or HP will have about 2 GB of RAM. Most computers on the market will support between 4 and 8 GB of RAM maximum.

Computer RAM
A computer memory RAM stands for Random Access Memory. It denotes a primary memory for the computer system. RAM works when we type or do a job or an event which is not saved yet. RAM can not exist otherwise it is saved in the hard drive in the computer. Therefore, whenever there is an interruption in electricity the memory is lost. Now a days, modern operating systems has the auto recovery systems to recover the unsaved memory known as cache memory.
RAM is the virtual memory of your computer; the more RAM you have, the more programs you can run at one time. However, that is just a brief explanation.

Temporary storage in a computer is designated as RAM (Random Access Memory), and gets reset every time the computer is shut down; unlike permanent storage (Harddrives, Flash Drives). RAM allows a computer to run programs without bogging down the harddrive, which is much slower by comparison.
RAM is computer memory that can be accessed randomly and is generally used as the main memory available for programs. RAM modules are sticks of memory that can be placed into slots on a computer's motherboard.
