## Basics of Physics

DISTANCE It is the total length travelled by a body in its course of journey. Characteristics of distance are: It is a scalar quantity. In CGS system, its unit cm (centimeter). In MKS system, its unit is m (meter). DISPLACEMENT The shortest distance between the initial and the final states …

## Physics and it’s Quantities

INTRODUCTION TO PHYSICS Physics is a branch of science that deals with the matter and energy. Matter is a substance that has mass and occupies space. It exists in 3 physical states: Solid– They have definite volume and shape. Liquid– They have definite volume but they lack in having …

## What is Breadth First Search (BFS)

Breadth First Search is an algorithm for traversing elements from a data structure or searching tree.  Visiting each vertex and edge exactly in a well defined order is done in Graph travelers. Traversal of an element in graphically is well defined in searching algorithms. The first traversal in BFS accomplished …

## Work and Kinetic Energy

WORK DONE BY A CONSTANT FORCE The work done by a constant force acting on an object is equal to the product of the magnitudes of the displacement and the component of the force parallel to that displacement. W= Fd In condition a, there is a force but no displacement, …

## What is the Motion of a Body

MOTION When a body changes its position continuously with respect to a stationery object, which is taken as a reference point. It can be depicted by this graph: Motion includes both distance and displacement. Distance is a scalar quantity because it has magnitude only. Displacement is a vector quantity because …

In this blog I discussed about What is IP address and how to represent it. Generally IP address is represented in 32-bit format. In expansion of IP is Internet protocol address. Dot (.) is the decimal and this notation is used to represent as number format data into string of …

## What is QDOS or MS DOS

DOS is a command based operating system, in full DOS means disk operating system. It runs from a hard disk drive. We know an operating is a type of software that controls the computer hardware and other device functionalities. DOS belongs to MS-DOS referred as Microsoft disk operating system. MS-DOS …

## Variables in C language

A variable is name which can hold different values at different instances. Here in C a variable is name of memory location used to store data or value. Its value can be changed and it can be reused many times. It is one of the way to represent memory location …
