CONTENT

Program is a sequence of instructions which tells the computer what to do.

Programming is a process by which a user (programmer) specifies to the computer in a logical sequence, step – by – step what it wants it to do.

The computer is a machine and as such only understands machine language. It does not understand human language. Therefore, for humans to communicate with computer, they must understand the computer language (i.e. Machine Language). Programming Language is a medium or notation of communicating with the computer system. The process of writing the set of instructions in a language acceptable to the computer is called PROGRAMMING and the person who writes the instruction is called a PROGRAMMER.

TOPIC – COMPUTER PROGRAMMING LANGUAGE

Reference Book – A handbook on Computer Studies (PRACTICAL GUIDE) for Schools and Colleges by NiyiAdekolegan

CONTENT

Programming Language is a medium or notation of communicating with computer system. There are three types of programming Language.

  1. Machine Language (Low Level Language)
  2. Assembly Language (Low level language)
  3. High level Language

 

LOW LEVEL LANGUAGE

A low level computer language is either a machine language or assembly language.

 

MACHINE LANGUAGE

In machine language, instructions are written in binary. It consists of binary codes using strings of 0s and 1s. This is the only language computer understands. A program written in machine language is directly executable by the computer. Computer components are electronic in nature, which exist in two states ON or OFF. A program written in machine language is tedious, boring to write and to read, prone to error and such errors are difficult to detect and correct.

 

ASSEMBLY LANGUAGE

An assembly language program is one written using mnemonic code in which instruction names are to remember like MPY for multiply and STO for store). Assembly language program eliminates all the problems encountered using machine language. However, a translator called ASSEMBLER translates assembly language program to machine language because this is the only language in which a computer can run programs.

 

HIGH LEVEL LANGUAGE

These were developed to further ease the work of programmers making the programs problem oriented against machine – oriented low level language. The statements of high – level language are close to natural human language (i.e. English Language). A high – level language program is translated (compiled) by a COMPILER to an equivalent machine language programs. Each high level language has its own compiler.

Examples of high level languages are

  1. BASIC – Beginners All-Purpose Symbolic Instruction Code.
  2. COBOL – Common Business Oriented Language
  3. FORTRAN – Formula Translator
  4. ALGOL – Algorithmic Language
  5. C++
  6. PASCAL
  7. JAVA
  8. VISUAL BASIC
  9. LOGO
  10. ADA etc

 

EVALUATION

  1. What is programming language?
  2. List the THREE types of programming languages.

WEEK THREE Date ………………

TOPIC – BASIC PROGRAMMING

Reference Book – A handbook on Computer Studies (PRACTICAL GUIDE) for Schools and Colleges by NiyiAdekolegan

CONTENT

BASIC stands for BEGINNNERS ALL-PURPOSE SYMBOLIC INSTRUCTION CODE. It is a single easy to use language designed also for beginners. It is not only simple but also powerful. It is science oriented. Professor John Kemeny and Thomas Kurtz developed the language in 1964 at Dartmouth College, U.S.A., as a means of teaching students a simple language for programming a computer. The program can be used to solve problem covering a wide range of application on many different types of digital computer. Because the BASIC Language has been designed for ease of use and is readily available on most computers, program development can be achieved in minimum time.

There are different versions of Basic. They include:

  • Turbo Basic (T-BASIC)
  • BASIC PLUS
  • GW BASIC
  • QUICK BASIC (Q-BASIC)
  • VISUAL BASIC (V-BASIC)

 

EVALUATION

  1. What is BASIC?
  2. List FIVE versions of BASIC.

 

THE BASIC INTERPRETER

For the computer to execute your instructions in order to produce the desired result, the instruction must be first be interpreted to what the computer can understand by another program called the BASIC INTERPRETER (or TRANSLATOR). The BASIC interpreter converts your program into a form that can be executed directly by the computer.

 

KEYWORDS IN BASIC

This is also referred to as BASIC statement or a reserved word. It is an instruction in BASIC, which has a specific means to the compiler or interpreter.

  1. REM STATEMENT

    The REM statement is a remark statement. It is used to insert remarks in the program. Such remarks are used to explain what the program is all about.

    Example:

    10 REM This program finds the average of 5 numbers

  2. LET STATEMENT

    The LET statement is used to assign (or give) values to variables.

    Examples:

    10 LET A = B + C

  3. INPUT STATEMENT

    Input is used to assign or give values to variables while program is running. It can be used with both numeric and string variables.

    Examples:

    10 INPUT A, B, C

  4. PRINT STATEMENT

    The print statement tells your computer to display the output of the executed program on

    the screen of the monitor (VDU).

    Example:

    10 PRINT SUM

  5. END STATEMENT

    End Statement is an instruction used to terminate the program. One the computer encounters END statement, it automatically terminates the program.

  6. RUN STATEMENT

    The RUN statement is used to execute a program. In Q-BASIC, F5 is used to RUN a program. Note that the program will not RUN if any mistake or error is detected in it.

 

EVALUATION

  1. Write the function of the following BASIC keywords
    1. LET  (b) INPUT  (c) PRINT  (d) REM  (e) RUN

2. What is keyword?

G.S.M. TECHNOLOGY

GSM Stands for Global System for Mobile communication. It is an ICT telecommunication device. It is the most popular mobile phone in the world today. GSM allows network operators to offer “roaming” services. The word roaming is the ability of the customer to use their phones whenever they are at anytime (this has to do with the availability of Network).

With GSM, when you have a mobile phone with a line you can be connected to the whole world. You can roam to another region or country and use the services of any Network operator in the region that has a roaming agreement with your GSM network operator. Messages can be sent to another subscriber on the service and an acknowledgement of receipt provided to the sender SMS can also be used in a cell broadcast mode for sending messages. Messages can be stored in the SIM card for later retrieval.

Prominent GSM operators in Nigeria include:

  1. Globalcom (GLO)
  2. MTN-NG
  3. ECONET/V MOBILE/CELTEL/ZAIN
  4. NITEL/MTEL
  5. MULTILINKS
  6. VISAFONE
