Combinational Circuits (Adder, Subtractor, Encoder, Decoder, and Multiplexer

Combinational Circuits Definition: In simple terms a circuit in which output depends only on the inputs but not on the state of that circuit is known as combinational circuits. We have different types of combinational circuits like Adder, Subtractor, Encoders, Decoders, Multiplexers and De-Multiplexers.There are lots of books you can follow to study these circuits, so there is no need of going  in-depth study of these circuits here, at this post I will give you some tricks or ideas how to use knowledge of these circuit in solving GATE problems, and how to create a circuit for a given function for these Adder, Subtractor, Encoders, Decoders, Multiplexers.Here is an applet which I have used in my Digital Logic post...

Add java applets in your blogger blog

ADD JAVA APPLETS IN YOUR BLOG Hello reader if you are here it means you want to add some java applets in your blog post, if you have your domain its not a big deal for you to add java applets in your blog but if you are using some blog services like blogger which I am using you feel lots of problems because you do not have a directory to save java files over there, so you have to fetch java applets from other directories or another sites which is useful for your blog post. Here I am writing step by step process to add JAVA APPLETS into your blog. Here it a code snippet: <applet code="GatesApplet.class" codebase="http://www.chem.uoa.gr/applets/appletgates/" height="370" width="480"> here code="xxxxxxxxxxx" denotes the class which is the class file for the applet here codebase=...

BOOTING OF AN OPERATING SYSTEM OR UNDERSTANDING OF HOW OS BOOTS

HOW OS BOOTS  Hello every one here I am going to explain how operating system boots i.e what happens when we start our PC. This is a very large process and here I am presenting it in a short form. When we power on the computer then it takes some time, until it gets power good signal and in this duration it sends a reset signal to CPU. Power good signal is a sign that shows that it is appropriate to start the booting sequence. The value of power good signal is generally 5V. When the booting of BIOS starts it first do the POST (power on self test) which checks the devices that is connected and if there is an error it makes notification in the form of BEEP (A sound of indication ). The BIOS then looks for other devices like ROM to see if any of them have BIOSes. Normally, the...
