RAM, also known as random access memory, refers to the most common computer memory. Programs can use RAM to perform necessary tasks once the computer is turned on. RAM is also considered an integrated circuit (IC) memory chip that allows information to be stored or accessed in any order. It is true that all RAM storage locations are equally accessible.
There are significant factors to consider when buying RAM. For example, computers running graphic design programs (those used by web designers, video editors, etc.) generally require more memory (RAM) than computers used for simple word processing operations. To figure out how much memory your computer should have varies by the size of the software you plan to run.
Desktop or laptop computers save data in two ways. One is on the hard drive, which is also called permanent memory, and the other is in random access memory, which is also known as temporary memory, where information is saved while the software is running. RAM, being a chip-based storage within the computer, has the memory stored which is usually measured in megabytes (MB).
Buyers should consider several factors when purchasing a new RAM. First-time computer buyers should look for models with at least 512MB of RAM or more. It will vary depending on the type of programs you are going to run. Make sure computing devices like this can be upgraded and this goes with the motherboard.
Today, most computers use a type of memory technically called DDR2. However, it is also called DDR3, which is now finally making its way to PC systems. In terms of prices, DDR3 is quite a bit more expensive than DDR2. As for the specifications, it is best to have at least 2 GB of memory in any computer system and preferably 4 GB. Of course, the faster your computer’s memory speed, the better performance it will have.
Since random access memory is what the computer uses to run applications and data on its operating system, it really should provide higher specs. Technically savvy people generally agreed that computer users need at least 256MB for Windows XP and Mac OS X.
So if the main purpose of your computer is playing games or heavy graphics work, always check the video RAM. Desktop computers can be easily upgraded. But when it comes to laptop technology (where every new generation always comes on the market), RAM keeps increasing. So be careful to choose the one that really suits your needs. Decide what type of system you will need and go for it.
