The complete computer made up of the CPU, memory and related electronics (main cabinet), all the peripheral devices connected to it and its operating system. Computer systems fall into two categories: clients and servers. Clients are the user's laptop and desktop computers, tablets and smartphones, while servers share their data and applications with multiple users. Servers range from entry-level rack mounts to mainframes. See A computer system is sized for the number of users it handles simultaneously, the type of work performed (office, engineering, etc.) and the volume of data that must be stored. Platform Every application is written to run under a specific CPU/operating system environment. The largest client platforms are x86/Windows, x86/Mac, ARM/Android and ARM/iOS. The largest server platforms are x86/Linux and x86/Windows. See Number of CPU Cores The more CPU cores, the more simultaneous processing. Modern desktop computer CPUs have two, four or eight processing cores, and servers can have from two to 64 or more. In addition, multiple machines can be tied together to work as one (see Clock Speed The gigahertz (GHz) rate of the CPU determines internal processing speed. See Disk and Memory The disk capacity determines the amount of information immediately available to all users. A computer's memory capacity determines how many applications can run efficiently at the same time. Fault Tolerance The use of redundant processors, peripherals and power supplies provide co...

Computer vision is a field of artificial intelligence (AI) that enables computers and systems to derive meaningful information from digital images, videos and other visual inputs — and take actions or make recommendations based on that information. If AI enables computers to think, computer vision enables them to see, observe and understand. Computer vision works much the same as human vision, except humans have a head start. Human sight has the advantage of lifetimes of context to train how to tell objects apart, how far away they are, whether they are moving and whether there is something wrong in an image. Computer vision trains machines to perform these functions, but it has to do it in much less time with cameras, data and algorithms rather than retinas, optic nerves and a visual cortex. Because a system trained to inspect products or watch a production asset can analyze thousands of products or processes a minute, noticing imperceptible defects or issues, it can quickly surpass human capabilities. Computer vision is used in industries ranging from energy and utilities to manufacturing and automotive – and the market is continuing to grow. It is expected to reach USD 48.6 billion by 2022. Computer vision needs lots of data. It runs analyses of data over and over until it discerns distinctions and ultimately recognize images. For example, to train a computer to recognize automobile tires, it needs to be fed vast quantities of tire images and tire-related items to learn...

Computers have revolutionized our lives. They help us get repetitive tasks done quickly and accurately. And they are tireless and do not fear complexity. Computers are able to process data and perform operations at a rate of millions per second. They can get a task done much faster compared to the time it would a human to complete the same task. Having access to a personal computer also gives you the opportunity to use the plethora of information and free resources available on the web. This in turn can help you learn new skills and possibly improve your quality and standard of life. But what are computers, exactly – and more specifically what is a PC? In this article you'll learn the basics of computers: what they are, the different kinds of computers available, and how they work. What is a computer? A definition for beginners Most of us use computers everyday. You can use them for work – when you want to edit a word document, attend a video conference, or send an important e-mail. You an also use them for entertainment purposes – such as browsing through social media or playing a video game. And now more than ever, many people use computers to consume educational content and gain new skills. They are so popular in our day to day lives, but do we ever stop to think what they actually are? Or how they work to accomplish various tasks at high speeds? Or what parts they're made of? A computer is a tool that accepts some input and can then easily manipulate and process the di...

software, instructions that tell a computer what to do. Software i.e., the physical components of a computer system. A set of instructions that directs a computer’s hardware to perform a task is called a program, or software program. The two main types of software are network software, which coordinates communication between the computers linked in a network. Software is typically stored on an external long-term memory device, such as a hard drive or magnetic diskette. When the program is in use, the computer reads it from the storage device and temporarily places the instructions in random access memory (RAM). The process of storing and then performing the instructions is called “running,” or “executing,” a program. By contrast, software programs and procedures that are permanently stored in a firmware, or “hard software.” This article was most recently revised and updated by
