RAM is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is found in servers, PCs, tablets, smartphones and other devices, such as printers.Main Types of RAM
There are two main types of RAM
DRAM (Dynamic Random Access Memory)
SRAM (Static Random Access Memory)
DRAM (Dynamic Random Access Memory) – The term dynamic indicates that the memory must be constantly refreshed or it will lose its contents. DRAM is typically used for the main memory in computing devices. If a PC or smartphone is advertised as having 4-GB RAM or 16-GB RAM, those numbers refer to the DRAM, or main memory, in the device.
More specifically, most of the DRAM used in modern systems is synchronous DRAM, or SDRAM. Manufacturers also sometimes use the acronym DDR (or DDR2, DDR3, DDR4, etc.) to describe the type of SDRAM used by a PC or server. DDR stands for double data rate, and it refers to how much data the memory can transfer in one clock cycle.In general, the more RAM a device has, the faster it will perform.
SRAM (Static Random Access Memory) – While DRAM is typically used for main memory, today SRAM is more often used for system cache. SRAM is said to be static because it doesn't need to be refreshed, unlike dynamic RAM, which needs to be refreshed thousands of times per second. As a result, SRAM is faster than DRAM. However, both types of RAM are volatile, meaning that they lose their contents when the power is turned off.A memory upgrade is one of the fastest, easiest, and most affordable ways to immediately improve the performance of your computer. If your PC laptop, desktop, workstation, or Mac system is running slowly, installing more memory takes as little as five minutes and delivers immediate and lasting improvements. Speed up your system, increase responsiveness, multitask with ease, and extend the lifespan of your computer with a reliable desktop memory, laptop memory, or Mac memory upgrade.

packages that different companies advertise. This is necessary because after all you are buying a piece of equipment that will most likely store a majority of your personal information and hopefully last you a few years. For those two reasons alone people tend to put as much effort into researching computers, as they do cars and other more expensive investments.On the other hand, a strong population of people are so loyal to certain brands (cough.. Apple) that they do not research optional products as much as they could/should and tend to over pay for what they can get elsewhere.Many people consider memory, or RAM (random access memory) to be the most important aspect of a computer. Rightfully so, RAM has a lot to do with the speed, and overall performance of your computer .For practical purposes, it could be said that the proper functioning of RAM memory is essential in a computer because it is one of the components that most directly affects its good performance, especially in terms of speed.As we have already seen, RAM is responsible for “helping” the processor in its operations, so that it “holds”, for memory purposes, all the instructions and data that the processor needs to use when running a program.So suppose you want to run several programs on your computer, tablet or smartphone at the same time. For example, a text editor, a browser with 3 open tabs and a business program. If the RAM is in good condition and has enough capacity, you shouldn’t have any problems.Now imagine that you want to keep using more programs at the same time, or that you want to use more modern programs with higher hardware requirements. For example, in addition to what we saw in our previous example, there are 10 more browser tabs and 3 new and highly demanding enterprise software. In this type of situation, and unless you have a large RAM memory capacity, it is likely that it will start to suffer and your computer will suffer from it.
