Binary logic deals with variables that take on two discrete values and which operations that assume logical meaning. The two values of the variables take may be called by different names (e.g true and false, yes and no). But for our purpose, it is convenient to think in terms of bits and assign the values…
Write a code for creating a website using HTML or HTML5? This basic build block concept is required for web page development. The recent version is HTML5 so we will most probably use HTML 5 coding structure for creating a website. Code for Creating a Website Using HTML <!doctype html> <html lang=”en”> <head> <meta charset=”utf-8″>…
Simply in digital logic, a universal logic gate is a logic gate that can be used to construct all other logic gates like AND, OR & NOT. These basic gates can be represented or created with the help of universal digital logic gates. NOR gate – Universal Logical Gate It is the combination of NOT…
Web protocols? First of all, protocols are the rules that describe how clients and servers communicate across a network. There are several different protocols used by the Internet. The Internet uses several different protocols to communicate across the network. The protocols used currently were developed many years ago, and are similar in concept to the rules…
Computer Security The need for automated tools for protecting the files and other information stored on the computer became evident. This is especially the case for a shared system as like the internet. Thus, computer security is the generic name for the collection of tools designed to protect data and to prevent hackers. Network Security…
Introduction to QBasic Quick Beginners, All-Purpose Symbolic Instruction Code is a high-level programming language developed by Microsoft Corporation, the USA in 1985. It is modular programming, where programming is divided into different modules or procedures. Q BASIC uses English like words and Mathematical symbols to write programs. Once you learn QBASIC programming it will be helpful to learn another high -level…
Gray code belongs to a class of codes called minimum change code in which the only one-bit code group changes when going from one step to the next. This is an un-weighted code which means that there are no specific weights assigned to the bit positions. Advantages of the Gray Code In the Gray Code,…
A URL (Uniform Resource Locator) is a form of URI and is a standardized naming convention for addressing documents accessible over the Internet and Intranet. An example of a URL is https://www.yourwebsite.com/, which is the URL for the Computer Hope website. A Uniform Resource Locator, or URL, is a text string that supplies an Internet…
Question: What is Computer? A computer is derived from the Latin word ‘Computare’ which means ‘calculate’. So according to this definition, a computer is a machine which can perform calculations at very high speed. A computer is an electromechanical device that works on command and performs mathematical and logical operations within a short time and with high accuracy. A…
Noise is any undesired signal in a communication circuit. Another definition calls noise unwanted disturbances superimposed on a useful signal, which tends to obscure its information content. There are many varieties of noise; however, the four most important to the telecommunication/data communication technologist are thermal noise, intermodulation noise, crosstalk and impulse noise. Noise refers to…
