How to differentiate different types of RAM?

For replacing or upgrading your desktop RAM, it’s very important to know what kind of RAM it is currently using. You can know that by reading the nameplate sticker sticked on it or looking physically. Every type of RAM operates in different voltage levels and frequency . Here inn this post we will discuss them one by one.


RAM stands for Random access memory. It helps processor to fetch data randomly as well as very fast. It stores the data temporarily for current running programs.

Like different generations of computer there are different generations of RAM. We will discuss one by one.

Easiest way to understand working of MOSFET

MOSFET┬ástands for metal oxide semiconductor field effect transistor. Like common transistors,it is also used as amplifying and switching device.The main difference from bi-polar transistor is that it’s gate (which is equivalent to base of a bipolar transistor) is electrically insulated.The metal-oxide insulation, commonly silicon di-oxide provides very high input resistance which makes the device suitable for different types of applications.

Linear Potentiometer VS Logarithmic potentiometer

Potentiometers varies potential difference between it’s terminals.It’s a very common and useful device used to vary voltage, current as well as gain in a circuit. Depending upon the physical size and form factor there are various types of Potentiometers.In this post we will differentiate potentiometers (in short POT) on the basics of Output Response with respect to angular displacement of the knob.

Types of processor package. PGA vs BGA vs LGA

PGA (pin grid array) is one type of processor packaging which offers more pins than DIP( dual inline package ). It’s a square or rectangular shape package. Pins are arranged in a matrix like manner at the bottom side of the processor. Pins are generally spaced 2.54 mm (0.1″) apart, and may or may not cover the entire underside of the package.
