RAM, ROM what are they and how do they affect my computer

RAM, or Random Access Memory, refers to the amount of‘working memory’ that your computer has. More specifically, RAM is the feature of a computer that allows programs to run. The more
RAM that a computer has, the faster programs will run. Having more RAM also allows the user to run more programs concurrently. For this reason newer computers, with more RAM, are able to process more programs at the same time. In order to keep your computer working as fast as possible, limit the number
of programs which are open at any one time. Present computers usually have 512 or 1024 MB of RAM.
ROM, or Read Only Memory, refers to the storage space that a computer can hold. Just like a glass which can contain only so much water, a computer can only hold so many programs and files. For this reason ROM has been likened to ‘long-term memory’.
