RAM or “Random Access Memory” is the part of computer hardware that loads up and runs the actual programs we use. For example, when you are working on a word document, the part of the software Microsoft Word, “winword.exe” is loaded in RAM. Otherwise if we were to run it from HDD (Hard Drive Memory), it will run very slow, since the PC has to access part of the software that is scattered on a spinning disk (SSD, solid state disk is faster than a traditional hard disk but is very slow compared to RAM on speed). The more memory we have on a PC, the more software it can load and execute. If we are running low on RAM than the PC operating system has to swap out programs from memory to make room for other programs. This can slow down the PC considerably. Easiest way to address this issue is to add more RAM to the system. This requires opening up the cover, which may be easier on desktops than laptops and then adding more memory sticks. They come in different speeds and configurations. Care must be taken to ensure that all the modules such as SIMM (Single In-line Memory Module) or DIMM (Dual In-Line Memory Module) are of same characteristics such as voltage, speed, form factors etc., If you need help with upgrading memory on you PC or Mac please reach out to us and we can make a recommendation based on your particular model.
