1 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL 1 Computers in the Home

2 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL 1 Objectives For the household appliances and common devices that are controlled by embedded processors: 1.State their common characteristics/ attributes 2.Name these household appliances and common devices

3 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL 1 Computers are found in many areas of our life. The type of computer that most people are familiar with is the desktop computer. Introduction A typical desktop computer

4 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL 1 Not all computers are shaped like a desktop computer. In fact, some computers do not look like desktop computers at all. Introduction A panel computer

5 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL Household Appliances that are Computers Characteristics of a Computer

6 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL 1 Is washing machine a computer?

7 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL Household Appliances that are Computers Characteristics of a Computer Memory : Stores the amount of time needed for each type of wash Processing : Controls how much water to use. Controls the movement of the washing drum Output : Beeping sound when wash is complete Input : Type of wash required e.g. spin, soak, rinse Consider the typical washing machine:

8 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL Household Appliances that are Computers Characteristics of a Computer Consider the typical washing machine: It can be classified as a very simple computer. The washing machine runs only 1 program. It cannot be installed with other new programs.

9 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL Household Appliances that are Computers Household appliances that come with embedded processors can be considered to be very simple computers because the processors have the 4 characteristics of the von-Neumann machine. 4 Characteristics of a computer 1.It is able to input information. 2.It is able to process information. 3.It is able to store information. 4.It is able to output information.

10 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL 1 Is washing machine a computer? Yes 4 Characteristics of a computer 1.It is able to input information – Inputs the type of wash 2.It is able to process information. - Controls how much water to use 3.It is able to store information. - Stores the amount of time needed for each type of wash 4.It is able to output information.- Beeps when wash is complete

11 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL Household Appliances that are Computers Common Household Appliances that Have Embedded Processors Microwave Oven LCD Television Oven for making bread

12 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL 1 What are the common attributes of their household applicances? Go to the facebook to discuss: /group.php?gid=

13 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL 1 1.Input, process, output, memory 2.Pocket calculator, digital watch, digital camera, mobile phone 3.They are special-purpose computers because they cannot be installed with other new programs.

14 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL A Toy that Has an Embedded Processor When your equipment needs batteries or electricity to run, it probably has an embedded processor.

15 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL A Toy that Has an Embedded Processor Resistor - The little cylinder with many coloured strips, which controls electric current flow. Capacitor - The component that is coloured orange or green. It stores electricity. Transistor - The black little plastic block. This amplifies electric current. Processor - The long piece of black plastic with many legs. This controls the motion of the car. Electronic Component - Description

16 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL 1 By looking at its location, color, shape and size

17 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL Factors Affecting the use of Embedded Processors 1.Cost 2. Complexity 3. Power efficiency 4. Knowledge 5. Imagination The Human Transporter A complex processor

18 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL 1 1.A computer is any device that has the ability to input, output, process and store data or information. 2.Many household appliances are operated by embedded processors. These are special-purpose computers because they cannot be used for other jobs. Embedded processors help automate dull repetitive tasks. Summary

19 Uses of Computers in the Home C E L : C O M P U T E R S i n E V E R Y D A Y L I F E CEL 1 3.Embedded processors are more widely- used now. 4.A few embedded processors can be found in household appliances. 5.Exploring the internal components of household appliances can be dangerous because there are components that store electricity. 6.High cost, complexity, high power consumption rate and limited knowledge are factors that used to limit the use of embedded processors.
