Optical character recognition or optical character reader is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene-photo or from subtitle text superimposed on an image.

Discuss about uses and impact of computer

Computers and Their Impact The extreme increase in the use of computers has drastically changed the lives of many people. Computers, as Sherry Turkle in “Who Am We” discussed, initially were used as simple calculators, but through the years they have come to be valued as more than simple machines (442). “The computer has gained […]

What is Characters & Strings in a Programming Language – C program basics

Characters & Strings Another type of data is textual data which can either be single characters or a sequence of characters which are called strings. Strings are sometimes used for human readable data such as messages or output, but may also model general data. For example, DNA is usually encoded using strings consisting of the […]

Types Of Variables in C programming – Basics of computer programming – Free Study Material

A variable’s type (or data type) is the characterization of the data that it represents.A computer only “speaks” in 0s and 1s (binary). A variable is merely a memory location in which a series of 0s and 1s is stored. That binary string could represent a number (either an integer or a floating point number), […]

Mathematic Variables For C Programming – Variables – Learn Basics of C programming – Free Online Studymaterials

Variables In mathematics, variables are used as placeholders for values that aren’t necessarily known. For example, in the equation, x = 3y + 5 the variables x and y represent numbers that can take on a number of different values.Similarly, in a computer program, we also use variables to store values. A variable is essentially […]

Flow Control Of A Computer program Process – Computer Basics study materials

The flow of control (or simply control flow) is how a program processes its instructions.Typically, programs operate in a linear or sequential flow of control. Executable statementsor instructions in a program are performed one after another. In source code, the order that instructions are written defines their order. Just like English, a program is “read” […]

Documentation, Comments, and Coding Style Of C Programming – Online Studymaterial

C code is not just functional, it is also wonderful. C code is organized, easy to read, and well documented. Organization can be achieved by separating code into useful functions and collecting functions into modules or libraries. Good organization means that at any one time, we only need to focus on a small part of […]

Syntax Rules & Pseudocode

Programming languages are a lot like human languages in that they have syntax rules.These rules dictate the appropriate arrangements of words, punctuation, and other symbols that form valid statements in the language. For example, in many programming languages, commands or statements are terminated by semicolons (just as most sentences are ended with a period). This […]

Basic C Program Structure – C program basic introduction – Free Study Material

Programs start out as source code, a collection of instructions usually written in a high level programming language. A source file containing source code is nothing more than a plain text file that can be edited by any text editor. However, many developers and programmers utilize modern Integrated Development Environment (IDE) that provide a text […]

Combuting Basics – Uses Of Computer – Free Study Material

Computing Basics       Everyone has some level of familiarity with computers and computing devices just as everyone has familiarity with automotive basics. However, just because you drive a car everyday doesn’t mean you can tell the difference between a crankshaft and a piston. To get started, let’s familiarize ourselves with some basic concepts. A computer […]

Computers Ability to Problem Solving – How Computers do the Problem Solving – Free Studymaterial

Problem Solving Computer Science is about problem solving. That is not to say that only Computer Science is about problem solving. It would be hubris to think that Computer Science holds a monopoly on “problem solving.” Indeed, it would be hard to find any discipline in which solving problems was not a substantial aspect or […]

Basic Introduction To Computer science – What is Computer science and How it is Used in Real Time

Computers are awesome. The human race has seen more advancements in the last 50 years than in the entire 10,000 years of human history. Technology has transformed the way we live our daily lives, how we interact with each other, and has changed the course of ourhistory. What is Computing? Today, everyone carries smart phones […]
