Week 1:
TOPIC: TECHNOLOGY OF DIFFERENT INFORMATION AGE I
Information Age:
Information age refers to the developmental stages in man’s history. In the early years, man was conscious of the necessity of tools, until the need for counting began to arise. Man, as historians and scientists agree, has gone through major developmental stages. It is essential to go through the ages and examine the major developments that characterized them as a prelude to how Computers and Computing came into existence.
The ages are:
Stone age
Iron age(hoe and cutlass)
Middle age(feather,pen and ink)
Industrial age.(machine)
Electronic age
Computer and Information age
Stone Age:
This is a broad pre-historic time period (Approximately 500,000 BC 10,000 BC) when humans widely used stones for tool making. During this period… Click here to order the complete Computer Science Lesson Note for JSS1 first term
Week 2:
TOPIC: COMPUTING DEVICES I (PRE-COMPUTER AGE TO 19TH CENTURY)
CONTENT
Man has put in every effort to have better methods of calculations. As a result of man’s search for fast and accurate calculating devices, the computer was developed. Essentially, there are three kinds of computing devices: manual, mechanical and automatic.
Manual Devices or Mechanical Calculating Tools : Examples are
1. Abacus
2. Slide rule
Mechanical Counting Machines: Examples are
1. John Napier bone
2. Blaise Pascal machine
3. Gottfried Leibniz machine
4. Joseph Jacquard loom
5. Charles Babbage analytic machine
Automatic Devices or Electronic Counting Machines: Examples are
1. Herman Hollerith punch card
2. John Von Neumann machine
EVALUATION
1. Mention three kinds of computing devices that you know.
2. Give two examples of each above.
ABACUS
The first calculating device was probably Abacus. The Babylonians invented it. It is… Click here to order the complete first term Computer Science Lesson Note for JSS1
