Second Term JSS2 Computer Science Lesson Note

 

Week One: Revision

INTRODUCTION:

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

 

Week Two: Basic Language

INTRODUCTION:

A computer language is a special language understood by a computer. It consists of various

commands that we give to the computer to do any work.

A programming language is a vocabulary and set of grammatical rules for instructing

a computer or computing device to perform specific tasks. The term programming

language usually refers to high-level languages, such

as BASIC, C, C++, COBOL, Java, FORTRAN, Ada, and Pascal.

Each programming language has a unique set of keywords (words that it understands) and a

special syntax for organizing program instructions. To learn more, click here.

 

Week Three: Simple Basic Statement

INTRODUCTION:

We will write your first BASIC program. In it, you will see examples of PRINT, CLS,

and END commands. Their roles in the program may or may not be apparent at the time, but,

as they’re so vital to the BASIC language, they will be discussed here.

Program Example

10 CLS

20 PRINT " Helloooooooooooooo, world!"

30 PRINT "I’m learning about commands in BASIC."

40 PRINT "This text is being printed via the PRINT command." To learn more, click here.

 

Week Four: Graphic Packages 1

INTRODUCTION:

A graphics package is application software that enables a computer user to create images and

graphics. With graphic packages, book cover, magazines, logos e.t.c can be

created. A graphics package is an application that can be used to create and manipulate

images on a computer. There are two main types of graphics package: painting packages.

drawing packages.

TYPES OF GRAPHICS PACKAGE

Painting Packages

 A painting package produces images by changing the colour of pixels on the screen.

 These are coded as a pattern of bits to create a bit-mapped graphics file.

 Bit-mapped graphics are used for images such as scanned photographs or pictures taken

with a digital camera. To learn more, click here.

Week Five: Features of Graphic Package

INTRODUCTION:

Vector-mapped software is ideal for drawings, charts, graphs, and diagrams.It creates an

image by defining line, position, shape, and fill pattern. You plot or vector a series of points to

define a shape.

This shape is calculated into a mathematical formula called an algorithm. Image

manipulation and editing is automatically calculated by the computer when you

change parameters, making modifications easy and fast. The use of a vector-based program

requires preplanning and more computer savvy than a bitmapped program. To learn more, click here.

Week Six: Graphic Packages 2

INTRODUCTION:

A Graphics package may not be as detailed as you think. It can be a simple paint

package, which has features of shading, drawing line diagrams and many other

simple but effective features. These packages can be an alternative to

complicated DTP packages. As it is very difficult to draw with the mouse, many

people scan the drawings on the computer and now there are software packages,

which do not use a mouse.

New equipment is used by professionals so that they can get pictures from a variety

of places. A video grabber lets you get pictures from the television or a video

camera and you then can alter it on your computer. A digital camera is also very

popular as you can take pictures and then put them on your PC and alter them. This

also means that you do not have to pay for the development cost. You can also use

clip art for pictures. To learn more, click here.

 

Week Seven: ICT as a transformational tool

INTRODUCTION:

ICT – ICTs stand for Information and Communication Technologies and are defined,

for the purposes, as a “diverse set of technological tools and resources used to

communicate, and to create, disseminate, store, and manage information.” These

technologies include computers, the Internet, broadcasting technologies (radio

and television), and telephony.

AS A TRANSFORMATIONAL TOOL:  Information communication technology is so

important in the world today that it makes it necessary for every person to be

competent in the use of Information communication technology for the task they

have to accomplish. Organization of all sizes, even the smallest schools and

businesses, rely on computer to help them operate more efficiently and

effectively. To learn more, click here.

 

Week Eight: Benefits of ICT Gadgets

INTRODUCTION:

ICT is beneficial to our everyday lives as the world is fast becoming a global city.

Information and communication technology is a very broad term. It refers to

various gadgets that aid in communication such as mobile phones, radios and

satellite communication. The term is also used to refer to various means of direct

communication such as video conferencing.

In short, information and communication technology, better known in its

abbreviated form as ICT, is a tool that helps in improving communication among

businesses and commerce activities in different parts of the world. In fact, ICT is

so commonly used in the commerce field to communicate various financial matters

such as acceptance of money, producing receipts and transferring funds that ICT

and e-commerce have become almost synonymous terms. To learn more, click here.

 

Week Nine: ICT Gadgets: The GSM

INTRODUCTION:

 

GSM (Global System for Mobile Communications, originally Groupe Spécial Mobile) is a

standard developed by the European Telecommunications Standards Institute (ETSI) to

describe the protocols for second-generation digital cellular networks used by mobile

devices such as tablets, first deployed in Finland in December 1991. As of 2014, it has

become the global standard for mobile communications – with over 90% market share,

operating in over 219 countries and territories.

2G networks were developed as a replacement for first-generation (1G) analogue cellular networks,

and the GSM standard was originally described as a digital, circuit-switched network optimized

for full duplex voice telephony. This expanded over time to include data communications,

first by circuit-switched transport, then by packet data transport via GPRS (General Packet

Radio Services) and EDGE (Enhanced Data rates for GSM Evolution, or EGPRS). To learn more, click here.

Week Ten: ICT Gadgets

INTRODUCTION:

An information communication technology gadget involves the technology and the

applications which are used in creating communication, transmission and storage

devices. There are many ICT gadgets which are used in communication technology.

Some of them are:

1. GLOBAL SYSTEM FOR MOBILE (GSM): Global system for mobile

communication is an ICT gadget and second-generation digital technology.

GSM is a top-class standard gadget relied on by millions of people worldwide.

Today’s GSM is a huge success wireless technology and an unprecedented

story of global achievement. It is approximated that 80 per cent of the world

used GSM technology while making wireless calls. To learn more, click here.

Week Eleven: Revision

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

Week Twelve: Examination

Afterwards, we would write an examination, which would test our knowledge of what has

been taught so far.
