Why Do Computers Need Memory or RAM
RAM refers to random access memory of a computer. When you work on a computer, all your data or information is temporarily stored on RAM. It stores all your data in an organized manner and not like the old magnetic storage tapes that you needed to rewind and search in order to gain access to the desired information. With RAM, you do not need to search for your data. It controls and organizes your information in such a way that you may easily access it from specific locations. RAM makes your computer very efficient and fast, as well as saves your time and efforts in locating information.
If your computer’s RAM is increased, then you may also increase its speed. RAM allows storage space for your information before you have read or written this information from the hard drive. In fact, you may think of RAM as a temporary hard drive that is amazingly fast in action. It is a critical part of your computer, as it offers memory to run your programs. Since the capacity of RAM is lower than your computer’s hard drive, it can work at a much faster rate as compared to a hard drive. Thus, it can help you run multiple programs simultaneously.
RAM is also required to help you launch multiple programs at a high speed and avoid a system crash. Your programs and files are first transferred to RAM and your computer should have a decent RAM to support them. For example, a few MBs of RAM was sufficient to run a system a few decades back. However, you cannot run the present system on a few MBs. To support today’s gaming systems and make them perform at ultra-high speeds, you at least need to have a RAM of 2 GB. Thus, RAM is the breath of your computer system without which your data cannot survive.
