Informations of Tablet PC


Welcome to Know prices

A tablet personal computer, a class of tablet which runs an adapted version of a desktop operating system. A tablet personal computer is a portable personal computer equipped with a touch screen as a primary input device, and running a modified desktop OS designed to be operated and owned by an individual. The term was made popular as a concept presented by Microsoft in 2000 and 2001 but tablet PCs now refer to any tablet-sized personal computer regardless of the operating system. Unlike modern tablet computers, traditional tablet PCs usually had a physical keyboard. Tablet computers come in a range of sizes, currently ranging from tablet PCs to PDAs. Tablet personal computers tend to be as large as laptops and often are the largest usable size for mobile tablet computing while the new generation of tablet computers can be smaller and use a RISC (ARM or MIPS) CPU, and in size can border on PDAs.

 Tablets, like regular computers, can run a number of operating systems. These come in two classes, namely traditional desktop-based operating systems and post-PC mobile-based operating systems. Most tablet computers released since mid-2010 use a version of an ARM architecture processor for longer battery life versus battery weight, heretofore used in portable equipment such as MP3 players and cell phones. Especially with the introduction of the ARM Cortex family, this architecture is now powerful enough for tasks such as internet browsing, light production work and gaming. A significant trait of tablet computers not based on the traditional PC architecture is that the main source of 3rd party software for these devices tends to be through online distribution, rather than more traditional methods of boxed software or direct sales from software vendors. These sources, known as "app stores", provide centralized catalogues of software from both 1st and 3rd parties, and allow simple "one click" on-device software purchasing, installation, and updates.
