Input and Output Devices

Lesson 2

1. Input and Output Devices

Devices connect to the computer MOTHERBOARD via some kind of INTERFACE.
Common interfaces are PORTS, or connectors in the back or front of your PC, and SLOTS on the board itself. You can attach devices onto "cards" fitted into PCI or AGP SLOTS inside the computer.

Copy the following list into a document and save it as INPUT OUTPUT DEVICES in your theory folder.

Next to each item write down whether it is used for INPUT or OUTPUT

Scanner
Printer
Joystick
Plotter
Monitor
Keyboard
Graphics Tablet
Wireless mouse
Infrared pointer
Loudspeaker
VDU
Voice Synthesiser

See if you can add any more devices to this list. You may want to use www.wikipedia.org to help you search.


2. Homework 1

Draw a diagram of a computer system showing how the main components are connected; you may add any devices you wish to your system. If possible, show whether the device is connected to a PORT, or a PCI or AGP slot.


3. Homework 2

Write an algorithm and pseudocode for the following:

A teacher has 18 students in his class. He wants to create a "calculator" which must do only one job: prompt for each of 18 scores in turn and add each score so that, at the end, the total score and average can be displayed. Use a LOOP to complete the task.

Exam Revision 1

QUESTION 1

Sectors Control Unit Cylinders Program ALU Backing Store Internal Memory Track



In order to execute a ____________________ the computer must first load a file from its __________________ into its ____________________. The ___________________ then picks each instruction in turn, passing any mathematical or logical statements over to the ____________ until the entire sequence of instructions is completed.



Draw the process outlined above using any diagram you like, then copy the completed paragraph into your theory notebook.


At the end of this lesson, the completed answer will be posted. You may post any questions you like.

QUESTION 2

Write an algorithm and pseudocode to add 3 numbers entered by a user and find the average. The printed output should be The total is (total) and the average is (average)

QUESTION 3 (homework)

Write an algorithm and pseudocode to allow a teacher to enter all the test scores for a class of 10 students. The program should output the average score in the test.
