Computers & Internet. Computer Viruses. Computer viruses are pieces of computer code, designed to implant itself in programs or files with the idea of destroying, or changing the data transmitted.
Viruses can be spread through interchange of files and programs, loaded onto a computer and executed. They slow down computers, crash a system, or simply reroute data to other units. Virus numbers have risen since the 90s, and the U.S government has passed laws making virus introduction into computers of unknowing victims, a serious crime. Software companies have also sought to stem the tide by creating programs specifically for tracking down viruses and stopping them.
Computer History. When was the first computer invented?
Who invented it and in what year? Information on evolution of computers and the timeline of computer development. In 1937 Alan Turing's Turing machine pioneered the idea of machines that could complete well-defined tasks by being supplied with programs. In 1938, Konrad Zuse built the first binary digital relay computer. In 1943 the first general-purpose digital computer, ENIAC was made. When was the First Computer Made? The debate on the first computer ever made may vary according to the perception of what constitutes a computer. Who Invented the Computer? Ever wondered who invented the machine that allows you to read these very words while listening to music, maintaining a social profile and shooting at a bunch of terrorists, all at the touch of a button? History of Computer Processors Moore's Law observes that the number of transistors on a chip doubles every two years.
Computer Networking. Computer networks are interconnections of many computers.
Computers in a network share resources such as electronic mail, bulletin boards, and access to unique databases. Think of them as information highways for data. Networks are changing the computing paradigm from "number-crunching" to communicating. They have spawned a number of industries and helped organizations provide information and communication services to remote customers. In a computer network the individual stations, called nodes, may be computers, terminals, or communication units of various kinds. LAN vs. The two most popular network types today are LAN (Local Area Network) and WAN (Wide Area Network). TCP/IP Model Vs. TCP/IP is the communication protocol to connect hosts to the Internet, while OSI is a reference model for communication between end users in the network. Ideas for Intranet Names Having a catchy name for your intranet is important for the members/employees to feel connected with it.
Computer Performance. A computer's performance is judged by its speed, input rate, output abilities and analytical speed.
It is not easy to understand all that. So read the articles below! Why is My Computer So Slow There are many reasons why your computer could be running slow. It could be due to problems associated with low memory in the RAM to the number of start up services that you have loaded into your computer. How to Disable Overclocking You tried out overclocking to make your processor go that extra mile, but it didn't work out. Does Overclocking Make a Difference? Overclocking is about making computer processors, graphics cards and memory cards perform beyond their specified base limits. Dangers of Overclocking People who overclock their machines are well aware about all the dangers and the risks of doing so, and they are prepared to take a chance.
Benefits of Overclocking Overclocking a computer means enhancing it so that it functions beyond its capabilities. How to Overclock a CPU. Desktop Computers. Desktop computers or personal computers (PC) are intended for home or office use.
Personal computers or PCs are a mainstay in today's society. Desktops, as they are popularly known, can be used for various purposes like document processing, playing PC games, Email, and browsing the Internet. Business applications can range from process management applications, desktop publishing, graphic design to software, and web development. The desktop computer comprises an externally attached computer keyboard, mouse, computer monitor, and a processor unit called CPU. Find out more about desktop computers from the articles provided below. Are Desktop Computers on their Way Out? Computer. A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically.
Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem. In World War II, mechanical analog computers were used for specialized military applications. During this time the first electronic digital computers were developed. Originally they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).[1] Etymology The first use of the word “computer” was recorded in 1613 in a book called “The yong mans gleanings” by English writer Richard Braithwait I haue read the truest computer of Times, and the best Arithmetician that euer breathed, and he reduceth thy dayes into a short number.
History Rudimentary calculating devices first appeared in antiquity and mechanical calculating aids were invented in the 17th century. First general-purpose computing device.
