A printer is a peripheral which makes a persistent human readable representation of graphics or text on paper or similar physical media. Traditional printers are being used more for special purposes, like printing photographs or artwork, and are no longer a must-have peripheral; 3D printing has become an area of intense interest, allowing the creation of physical objects. An image scanner is a device that optically scans images, printed text, handwriting, or an object, and converts it to a digital image. Hand-held scanners, where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications.

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.

Hardware

A personal computer is a general-purpose computer whose size, capabilities and price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed systems to be used by many people, usually at the same time. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection, and through that to the Internet. A personal computer may be a laptop computer or a desktop computer running an operating system such as Windows, Linux or Macintosh OS.
