First Term JSS1 Computer Science Lesson Note

Week One: Technology of different information age

INTRODUCTION:

The counting of figures and other simple arithmetic operations are the greatest challenges

man has ever had before the invention of the computer. The counting move is done using

different parts of the body such as fingers and toes. Objects like stones, pebbles, sticks, and

drawings of lines of marks on the surface were also used for counting.

The technology of information ages can be grouped into four stages and these are:

1. Stone Age (primitive period): stones were used for making tools and weapons of the

primate period. In this era, stones were stricken together to make fire. Clay was also

used for making pots, jugs, and pottery e.t.c. To learn more, click here.

 

Week Two: History of Computer

INTRODUCTION:

Before the invention of the computer, counting figures was done with a finger, and also the use

of toe. Then later on man shifted to the use of stones. The stones often became a problem

sometimes, then another means cropped up until mechanics and electronic devices were

discovered.

Development of computer mechanical devices are these devices that porter their task without

making use of electricity. Examples are

1. Abacus: Abacus was developed in china. It is a wooden frame with string on which

colourful beads are stung. To learn more, click here.

 

Week Three: Generations of Computer

INTRODUCTION:

There are five generations of computers which are:

1. First Generation: The first generations of computers were developed between 1939-

1945. The major component of this generation of computers was vacuum tubes. These

computers were cumbersome in size, they generate lots of heat and noise, and they are

very slow in speed less reliable and efficient.

2. Second Generation of  Computer: The second generations of computers were

developed between 1955-1964. The major component of this computer was

transistors. They were not as big as the first generation of computers. They generate

less energy and noise, they work faster, and they are more reliable and more efficient.

Week Four: Basic Computer Concept

INTRODUCTION:

A computer can be described as a machine or a device that accepts data under the control of a

stored program in a prescribed form, process data and supply the result as information in a

specific form. It performs three major functions such as:

1. It accepts data

2. It process data

3. It supplies information (output)

Week Five: Data and Information

INTRODUCTION:

“Data” comes from a singular Latin word, datum, which originally meant “something given.”

Its early usage dates back to the 1600s. Over time “data” has become the plural of datum.

“Information” is an older word that dates back to the 1300s and has Old French and Middle

English origins. It has always been referred to as “the act of informing,” usually in regard to

education, instruction, or other knowledge communication. To learn more, click here.

 

Week Six: Information Transmission

INTRODUCTION:

Information transmission can be referred to as the various ways or more of spreading or

passing information from one place to another.

Ways of transmitting Information

 

1. Ancient Method: The various ways of transmitting information in the ancient time

are,

 oral

 beaten drums

 town crier

 whistling

 drawing diagrams

 making representation

Week Seven: Information Evolution and Communication Technology

INTRODUCTION:

1.  Invention Of Printing: Printing and paper were invented in china in 1940, a German

Johannes Gutenberg developed a moveable printer machine which was used to replace

hand printed text.

2. Invention of Television: An American photo Taylor Farnsworth invented the Cathode ray

tube (CRT) used in picture production. The first television was invented by Williams

Crooks in 1878 (Black and white)

3. Invention Of Radio: James Clerk Maxwell and Heinrich Harte develop a theory of

electromagnetic wave in 1873

4. Invention Of the Computer: the computer took several stages before it come into existence.

From the early counting devices such as a finger, sticks, stones, and pebbles, to mechanical

counting devices such as Abacus, slide rule, Napier bones, pascal calculating machine

e.t.c. To learn more, click here.

 

Week Eight: Classification of means of transmitting information

INTRODUCTION:

 There are various ways of transmitting information and these can be classified into

two of which are as follows. 

Electronic Means

 

 Print out copies

 Telephone

 Radio

 Television

 Internet

 Telex

 Satellite

 S.M

Week Nine and Ten: ICT Application in Everyday life

INTRODUCTION:

Information Communication Technology (I.C.T)

Information communication technology is often used as an extended synonym for

information technology (IT). Still, it is a more specific term that stresses the role of unified

communication and integrated Telecommunication ( Telephone line and wireless signals).

Computer as well as necessary enterprises software, middleware, storage and audio-visual

the system enables a user to access, store, transmit and manipulate information. To learn

Week Eleven:

This week, we would be doing a revision of all that we learned during the term.

 

Week Twelve  Examination

Afterwards, you would write an examination, which would test your knowledge of what has

been taught so far.
