What is RAM and How Much Should I Have?

When it comes to RAM, or Random Access Memory, people looking to buy a new computer often ask how much RAM they need for their setup, or if they even need any. Well look no further.

What is RAM? Well, RAM stands for Random Access Memory as I stated above, and there are many different types of RAM like DRAM (Dynamic RAM), SRAM (Static RAM), and ROM (read only RAM).

OK, that was probably a lot to process but I'll break it down as best I can. If you are buying a computer for general use, you probably want DRAM, because it is extremely efficient, high quality and cheaper than SRAM. DRAM usually has a response time of 60 nanoseconds versus SRAM's much faster 10 nanoseconds. BUT the situation that would require this level of speed is very unlikely to arise to the average person. Therefore I would go with the Corsair Vengeance DDR4 DRAM, which I personally use and have had nothing but positive experience with.

ROM vs RAM. This is a simple one, ROM is actually just special memory used to store programs that launch when you boot, such as Console. It is also used to store diagnostics programs and other default Windows programs. It's just a misconception that these are similar.

Well how much RAM do I need? First of all, RAM is measured in Gigabytes, and is sold in these measurements from 4, 8, 16, to 64 gigabytes. 8 GB of DRAM is usually more than enough for most people, but students could likely get away with 4GB and have no problems. Avid gamers should get 16 GB and people interested in computer design or CAD could need up to 64 GB.

Well, thanks for reading, and I hope you now understand RAM!
