Algorithm and Flowchart for SS2

Definition Algorithm
Algorithm can be defined as the set of rules and sequential steps that define how a particular problem can be solved in finite and ordered sequence.
Function of Algorithms
An algorithm generally takes some input, carries out a number of effective steps in a finite amount of time, and produces some output.

Characteristics of Algorithms
Every algorithm should have the following five characteristic features
1. Input
2. Output
3. Definiteness
4. Effectiveness
5. Termination
Example1 : Write and algorithm to compute the area and circumference of a cycle given the diameter d. Use the formular
Solution
Step 1: Start
Step 2: Get the diameter d
Step 3: Compute
Step 4: Compute
Step 5: Compute
Step 6: Display the results
Step 7: Stop
Example 2 : Write an algorithm that tells you how to wash dishes
Solution
Step 1: start
Step 2: scrape food off dishes
Steps 3: wash the dishes with soap and water
Step 4: Rinse the dishes
Step 5: Dry them
Step 6: Stop
Example 3: Write an algorithm to evaluate the equation y = a(b-c)^2/d+2
Solution
Step 1: start
Step 2: input the value of a, b, c, d
Step 3: Value of y is to be calculated
Step 4: Calculate the value of b-c and denote f
Step 5: Calculate the square of f
Step 6: Multiply f by a and denote g
Step 7: Calculate the value of d+2 and denote h
Step 8: divide h by g
Step 9: We get the value of y
Step 10: Print y
Step 11: Stop
Definition of Flowchart
This is the graphical representation of steps involved in solving a given problem. More formally, flowchart is a pictorial representation in which symbols are used to show the various operation and decision to be followed in solving a problem.
Some standard symbols used in drawing a program flow chart are:

BASIC Programming Language for SS1 BASIC stands for Beginners All-purposed Symbolic Instruction Code. It was developed in 1964 by Professor John Kemeny and Thomas Kurtz to teach students at Dartmouth College. It has undergone series of historical development, which has resulted in several forms of the language. Versions of BASIC 1. BASICA 2. GWBASIC 3. Torbo BASIC 4. Quick BASIC 5. VB.NET BASIC CHARACTER SET 1. Alphabetic Characters – A to Z 2. Numeric Character – 0 to 9 3. Special Characters – 0 + % ^ # = ( ) etc BASIC VARIABLES A variable is a quantity that changes during the execution of a program. It can also be defined as a name that is used to represent some storage location. Types of Variable 1. Numeric Variables : These are used to store numeric values such as 23, 98, etc. There are two major types of numeric variables, which are; Integer variable and real variable a. Integers are whole numbers without decimal places. b. Real numbers are numbers with decimal places Hence Integ

Computing Devices I ( Pre-Computer to 19th Century) for SS1 Man has put every effort to have better method of calculations. As a result of man’s search for fast and accurate calculating devices, the computer was developed. 19 th Century Device Some of the 19 th century devices are: Abacus, Napier’s bones, Pascal’s calculator, Leibniz multiplier Jacquard’s Loom, Charles Babbage’s engine, Hollerith Census machine and Borrough’s machine. Abacus The first calculating device was probably the Abacus. The Chinese invented it. Components: It is made up of frame divided into two parts by a horizontal bar and vertical threads. Each thread contains some beads. It is known as Soroban in Japan and Suan Pan in china. Uses : to do simple addition and subtraction Napier’s Bone : In 1617 an eccentric (peculiar, unusual person) Scotsman mathematician named John Napier invented Logarithm which is a technology that allows multiplication to be performed via addition. Components : A set of eleven rods, wit

Computer Ethics for JSS 2 Definition of Computer Ethics Ethics is a set of moral principles that govern the behavior of a group or individual. Computer ethics can be defined as the set of moral principles that regulate the use of computers. Responsible use of Computer and Internet The following are the basic security measures taken to prevent damage to computer system. 1. There must be adequate ventilation. 2. Adequate space must be allowed between each system unit. 3. Avoid dust by using cover. 4. Avoid moisture. 5. Provision of air conditioners and fans or other cooling machines. 6. Provision of UPS (Uninterruptible Power Supply) and other electrical appliances to avoid loss of information and electrical damage to the system. 7. Adequate care must be taken to storage devices like diskettes, flash drive, CD/DVD writer drive, etc. 8. Disallow an unauthorized user from having access to your computer. 9. Ensure maximum security to files and information on the computer. 10. Provide comput
