Processor
If you’re in the market for a new computer, it’s necessary to understand the function of a processor. Also known as the Central Processing Unit or CPU, the CPU is essentially the “brains” of your computer. Without the CPU, you wouldn’t be able to play games, type research papers, or surf the Internet. Your computer would basically be a very expensive paperweight.
Memory e.g. RAM
Computer memory can refer to many types of memory within a computer, but, typically, it refers to random access memory (RAM). It is physically found on computer chips that are inserted onto the computer’s motherboard. RAM is electronic, rather than mechanical; that is, it does not have moving parts and therefore data access to it is very fast. Modern computers often have somewhere between 256 MB (megabytes) and 2 GB (gigabytes) of RAM, although there are, of course, computers with more or less RAM. RAM is also volatile, meaning that it gets lost when the computer is switched off.
