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.
