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.
If you are not comfortable cleaning the inside of your computer, call professional to do it for you.

1. True

multiple choices
1.c. Ergonomic Keyboard
2.a. predictive text input
3.b. multi-touch
4.c. graphics tablet
5.d. Voice recognition
6.c. Music production software
7.c. radio signals
8.c. gesture recognition

1. B

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
a fingerprint. The reader can be
set up to perform different functions for different
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
reasonable attempts to accommodate
the needs of physically
challenged workers.

With gesture recognition, the computer
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.

PTI assignment beyond the book and chapter 3


Task given by  Tri Djoko Wahjono, Ir., M.Sc.

beyond the book number 2 and 8

computer usage at sports

1. Instant replay

is the replaying of video footage of an event or incident very soon . instant replay is often used during live broadcast, to show a passage of play which was important or remarkable, or which was unclear on first sight.

In NBA basketball, the officials must watch an instant replay of a buzzer beater to determine if the shot was released before time expired. Since 2002, the NBA also has mandated installation of light strips on both the backboard and the scorer's table that illuminate when time expires, in order to assist with any potential review.
"The referee may use technical equipment to determine on a last shot made at the end of each period or extra period, whether the ball has or has not left the player's hand(s) within the playing time."
In field hockey, the International Hockey Federation allows the match umpire to request the opinion of a video umpire as to whether or not a goal has been validly scored, and whether there was a violation in the build-up to a goal.
In Motor Sports, video replays are used to review rules infractions and scoring disputes.
video replay is used to determine if a car has crossed the pit entrance before the pit was closed for a yellow flag, used to supplement electronic scoring to determine the positions in which cars exit the pits (during cautions), also determines if drivers are following pit road speed limits.

2. Soccer Goal Line Technology

There has been a need for goal line technology in soccer, particularly as TV replays are showing in retrospect wrong decisions by the referee.

Possible Options:

Smart Ball

A promising prospect has been a "smartball" loaded with an computer chip, jointly developed by German companies Cairos Technologies and the Fraunhofer Institute for Integrated Circuits, an engineering research and software development company, along with the Adidas athletic clothing and shoe company. 
The companies' technology uses a network of receivers around the field designed to track the ball's precise position in real time - including exactly when it has fully passed the goal line. That information would be relayed in less than a second to a watch-like device worn by the referee.


The Hawke Eye system uses three cameras focused on each goal-line, and each taking footage at 600 frames a second. Hawk-Eye is able to give a definitive decision on whether the ball has fully crossed the line, and relay this information in the form of an audible beep to the central referee within half a second. 
As the Premier League referees use headsets, the signal is easily sent to them. In other leagues, other methods such as through a watch can be used.

3. Fitness Organizer

Organizing Fitness could be done easily using software. BodyByte is one fitness organizer that plans your fitness needs. features :

  • Body Management - enables you to view and modify your User Profile details, and perform body state history recording (body weight, body measurements, body fat, blood pressure, heart rate, cholesterol and fitness levels).
  • Exercise Management - for exercise planning and recording.
  • Fitness Assessment Monitoring - you can record and track up to 16 fitness parameters along with your other body state indicators, which provides for a truly full body profile analysis.
  • Nutrition Management - used to view and print food items in the main country specific food database or Customized Food List, create recipes, compile meals and daily meal plans from food items in the database or food list, and record your intake history.
  • History Analysis and Reporting - reports can be generated for all recorded intake, exercise and body state history. You can view detailed listings, daily averages or time period-related aggregates, displayed in tabular and graph formats.
