RAM is an acronym for Random Access Memory. Electrically, RAM is a computer internal memory that stores programs and files that CPU use to execute instructions.

RAM is a volatile memory. That is to mean RAM stores data for so as long as the computer is powered. Perhaps, this is the reason why you have to set up your computer again in case of power failure, especially in desktop computers.

You can avoid this frustration by using Uninterruptible Power Supply (UPS) to power your computer. UPS provides you enough time to save your data to avert data loss.

Types of Random Access Memory (RAM)

RAMs are classified based on the technology used to manufacture them. The technology may be either based on capacitors or transistors.

There are two types of RAM namely Static RAM (SRAM) and Dynamic RAM (DRAM). The difference between the two RAMs is the use of either transistors or capacitors in its structure

SRAM. These RAMs whose structure is a matrix of 6 transistors only. Static is used here since SRAM retains data so long as the computer is powered. SRAM is very fast thus mostly used in the manufacture of cache memory.

DRAM.  The DRAM is composed of both transistors and capacitors. This RAM is dynamic in nature hence the name Dynamic RAM. The computer must continuously refresh DRAM memory to keep data.  Structurally, DRAM is in size thus cheaper than SRAM.

Random Access Memory (RAM) Location

Physically, RAM looks like thin bars with shiny contacts on one-end and square components on the flat sides. These RAM bars are popularly known as Dual Inline Memory Module (Dimms) as shown in below picture.

RAM DIMMs

Manufactures design computer motherboards with 2 to 4 memory slots specifically meant for RAM DIMMs. You can, therefore, easily plug in or plug out the DIMMs easily. However, you need to handle the RAM with care.

RAM Size and Processing Power

You must have heard you, friends or family, telling you that their computer has 2 GB, 4GB, 8GB, or 16 GB RAM. Have you ever wondered what all this means?

That is RAM size. The strength of RAM is determined by the size of the storage it can hold.

RAM size is measured in terms of Gigabyte (GB) of data they can store. The larger the RAM size the better the computer performance.

Thus, if you are planning to buy a computer or any device, remember to consider the one with higher RAM size. Such a machine will load faster without latency especially if you are interested in streaming movies or football.

How RAM increase Device Performance?

A computerised device uses the Central Processing Unit (CPU) to process information. The data CPU require to process information is stored in a Read Only Memory (ROM) in the hard drive.

The hard drive is very slow in retrieving data store in it.  Therefore, if the CPU was to load from hard drive, our computers, phones, decoders, and other electronic devices would be very slow. RAM assists in speeding since RAM is very fast in retrieving data.

The CPU fetches all the files it requires to load then stores them in RAM. Since RAM is fast, CPU can retrieve data very fast hence fast loading.

If RAM is big enough, it means all data can fit in RAM. Loading will, therefore, be very fast. That is why the bigger the RAM the better.

If RAM is small, only part of the data will fit. CPU will have to access the rest from the hard drive hence slowing the processing.

It is for this reason a computer with big RAM can multitask several programs at a go. For instance, a computer with a 16GB RAM will open browsers, a game, copy, and download files simultaneously.

The difference will be notable if you try doing the said tasks using a computer with 2GB RAM.

Now you know. Next time you buy any device be cognizant on the importance of a bigger RAM for awesome performance.
