Introduction And Components Of Tablet Pcs
A tablet personal
computer (tablet PC) is a portable personal computer equipped with a touch
screen as a primary input device, and running a modified desktop OS such as
android or iOS. The term was made popular as a concept in the years 2000 and
2001, but tablet PCs now refer to any tablet-sized (approx. 7" screen
size) personal computer regardless of the operating system.
Incidentally, according
to dictionary.com, tablet refers to a number of sheets of writing paper,
business forms, etc., fastened together at the edge; pad. Tablet personal
computers are mainly based on the x86 IBM-PC architecture and are fully
functional personal computers, supporting their touch-screen, instead of a
traditional display, mouse and keyboard. A stylus is preferred to operate a
tablet computer, because operating the typical desktop based OS requires a high
precision to select GUI widgets, such as a close window button.

Tablet Pcs
: How It Is Different From A Desktop Or A Notebook - Input Method, Size
- Touch screen
Tablet PCs are sleek, lightweight and affordable, so they must pack a bundle of features into a sleek package. This starts with the touch-sensitive screen. A tablet's screen has to serve as the monitor, keyboard, and touch pad to save physical space. The screens are capable of high-resolution color photos and HD-quality video matching that of notebook computers. Some tablet users opt to purchase a separate USB or Bluetooth keyboard for more extensive writing tasks.
- Processor
Tablet PCs must use a low-power, yet high-octane microprocessor, also known as the Central Processing Unit (CPU). Two popular tablet PCs, the Motorola Xoom and the View sonic G-Tablet, use the Nvidia Tegra 2 processor. A low-power processor allows the tablets to achieve the 8- to 10-hour battery life that the units can achieve at the sacrifice of processing speed. If you want the more powerful Intel Pentium processor or a top-of-the-line AMD chip, you might consider getting a full-scale laptop or maybe even a desktop PC.
- Memory
Tablet PCs typically pack 1 to 2 gigabytes (GB) of RAM, or Random Access Memory. This is plenty of RAM for basic tasks required of tablets, such as note taking, email reading and video viewing. The RAM helps the tablets load and swap out programs and files. Some tablets PCs are capable of RAM upgrades to 4 GB. This would benefit users who want to do moderate video editing on their tablets.
- Storage Capacity
Tablet PCs typically work online in the manner of a net book or networked computer. Therefore, hard drive space is held to a minimum if the unit has a native physical drive at all. Typically, tablet PCs come with 16 GB or 32 GB of internal flash memory. Storage can be upgraded with a Secure Digital High Capacity (SDHC) flash memory card of 4 GB, 8 GB, 16 GB, 32 GB or 64 GB.
- Integrated motherboard
Many of the tablet PCs functions are handled by an integrated motherboard that includes a graphics card, wireless network card, card reader, USB ports and mini HDMI port. Many of the files and programs, if not downloaded from the Internet, are loaded via a USB cable or from a flash drive. Usually, tablets do not have any DVD drives.
