 Android is a Linux-based operating system designed primarily for touchscreen mobile devices such as smartphones and tablet computers. (mobile usage)
It is currently developed by Google in conjunction with the Open Handset Alliance. Initially developed by Android Inc, whom Google financially backed and later purchased in 2005, Android was unveiled in 2007 along with the founding of the Open Handset Alliance, a consortium of 86 hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices.


Symbian is a mobile operating system (OS) and computing platform.
designed for smartphones and currently maintained by Accenture. Symbian was originally developed by Symbian Ltd., as a descendant of Psion's EPOC and runs exclusively on ARM processors, although an unreleased x86 port existed. The current form of Symbian is an open-source platform developed by Symbian Foundation in 2009, as the successor of the original Symbian OS.

Short Answer
1.-->2 types design of Tablet PC’s are slate Tablet PC and convertible Tablet PC.

-->The difference between those 2 design is the location of the system unit, whether it’s below the display or below the keyboard unit.

2. -->Motherboard  is the main circuit board of the system unit.

-->Computer chip is a small piece of semiconducting material on which the integrated circuit are etched.

3. -->The four basic operations of a machine cycle is fetching, decoding, executing, storing.

-->Register functions include storing thelocation from where an instruction was fetched,storing an instruction while the control unitdecodes it, storing data while the ALU computesit, and storing the results of a calculation.

4. --> omputers,peripherals, smart phones, PDAs, cars, andother consumer electronics are Bluetoothenabled.

-->A computer can become Bluetooth enabled by purchasing a Bluetooth wireless portadapter, Bluetooth PC Cards and ExpressCardmodules for traditional notebook computers andTablet PCs, and Bluetooth cards for smart phonesand PDAs.
5. --> ompressed air can be used to removes dust andlint from difficult-to-reach areas and removessticky liquid spilled on keyboards.

-->Before cleaning a computer, turn it off and unplug it from any electrical source.
Disconnect all cables from the port. Use compressed air to blow away dust on the computer opening. Then wipe the case of the computer using antistatic wipe, use cleaning solution and a soft cloth to clean the computer screen.
Prepare also antistatic wristband, vacuum cleaner, and antistatic wipe to clean the inside of the computer.

1. trackball, touchpad, pointing stick.

-a stationary pointing device
with a ball on its top or side

-a small, flat, rectangular
pointing device that is sensitive to pressure
and motion (Figure 5-10). To move the pointer
using a touchpad, slide your fingertip across the
surface of the pad.

-A pointing stick is a pressure-sensitive
pointing device shaped like a pencil eraser
that is positioned between keys on a keyboard

Move the mouse until the pointer on the desktop is positioned on the
item of choice.

Press and release the primary mouse button, which usually is the left
mouse button.

Press and release the secondary mouse button, which usually is the right
mouse button.

Quickly press and release the left mouse button twice without moving
the mouse.

Quickly press and release the left mouse button three times without
moving the mouse.

character recognition (OCR) is a technology
that involves reading typewritten, computerprinted,
or hand-printed characters from ordinary
documents and translating the images into
a form that the computer can process.

-Optical mark
recognition (OMR) is a technology that reads
hand-drawn marks such as small circles or
rectangles (Figure 5-31). A person places these
marks on a form, such as a test, survey, or questionnaire
answer sheet.

4.A fingerprint reader,
or scanner, captures curves and indentations of

for example, one finger starts
a program and another finger shuts down the

5.-Federal law that
requires any company with 15
or more employees to make

will detect human motions. Computers with
gesture recognition capability have the potential
to recognize sign language, read lips, track facial
movements, or follow eye gazes. For paralyzed
or speech impaired individuals, a doctor will
implant a computerized device into the brain.
This device will contain a transmitter. As the user
thinks thoughts, the transmitter will send signals
to the computer.
