Form 2 : CYBERLAW (15July2009)




Cyberlaw
is a term that encapsulates the legal issues related to use of communicative, transactional, and distributive aspects of networked information devices and technologies. It is less a distinct field of law in the way that property or contract are, as it is a domain covering many areas of law and regulation. Some leading topics include intellectual property, privacy, freedom of expression, and jurisdiction.

ETHICS IN GENERAL
A guideline is needed to stop the current technology products from being exploited for example replicating original CDs and selling them as pirated software, this unethical behaviour can be controlled by the code of conducts.

Unethical refers to any code of conducts that are not conforming to approved standards of social or professional behaviour.

Computer ethics is a system of moral standards or values used as a guideline for computer users.

THE TEN COMMANDMENTS OF COMPUTER ETHICS
The United States Institute of Computer Ethics has come out with the Ten Commandments of Computer Ethics. These principles consider the effective code of conducts for the proper use of information technology. The Ten commandments of computer ethics are :

1. You shall not use a computer to harm other people.
2. You shall not interfere with other people's computer work.
3. You shall not snoop around in other people's computer files.
4. You shall not use a computer to steal.
5. You shall not use a computer to bear false witness.
6. You shall not copy or use proprietary software for which you have not paid.
7. You shall not use other people's computer resources without authorisation or proper compensation.
8. You shall not appropriate other people's intellectual output.
9. You shall think about the social consequences of the program you are writing or the system you are designing.
10. You shall always use a computer in ways that ensure consideration and respect for your fellow humans.

THE DIFFERENCES BETWEEN ETHICS AND LAW

DEFINITION OF ETHICS
In general, ethics is a moral philosophy where a person makes a specific moral choice and sticks to it. On the other hand, ethics in computing means moral guidelines to refer to when using the computer and computer networks. This includes the Internet.

DEFINITION OF LAW
Law is a legal system comprising of rules and principles that govern the affairs of a community and controlled by a political authority.

Law differs from one country to another. In the era of technology, computer law is needed to clarify goods or actions that fall under the computer law. Computer law refers to all areas in law that requires an understanding of computer technology such as hardware, software and Internet.

Examples of laws of computing in Malaysia include the Malaysian Communication and Multimedia Act, the Computer Crime Act 1997 and the Telemedicine Act 1997.

Form 5 : Latest Programming Language

THE LATEST TYPE OF PROGRAMMING LANGUAGES

1. FIFTH GENERATION LANGUAGES

Fifth generation programming language (5GL) is an advance programming language which concentrates on solving problems using constraints given to the program.

In fifth generation language, the programmer just need to define the problem to be solve and the program will automatically code the program based on the problem definition.

Fifth generation languages are designed to make the computer solve the problem for you.
Fifth generation languages are mostly used in artificial intelligence research.
Examples of fifth generation languages include Prolog and Mercury.

2. NATURAL LANGUAGE

Natural Language programming aims to use natural language such as
English to write a program.

Instead of using a specific programming language syntax, natural language
programming will use normal English as the input to program software.

Such a technique would mean less technical programming knowledge
is required to write a program.
The programmer needs to define the program using normal language.

3. OPENGL (GRAPHIC LIBRARY)

OpenGL (Graphics Library) is a standard specification to describe the standard Application Programming Interface (API) for 3D/2D computer graphic applications.

OpenGL specification describes a set of functions and the exact behaviours that the 3D/2D application must perform.
OpenGL was developed by Silicon Graphics.

OpenGL is widely used in virtual reality, scientific visualisation, flight simulation and video game development.

Form 5 : Five Program Development Phases

In program development, there are five main phases. These phases are a series of steps that programmers undertake to build computer programs. The program development phases guide computer programmers through the development of a program.

The five main phases of program development are as follows:

PROBLEM ANALYSIS PHASE
During the problem analysis phase, the programmer will interview the client to find out what the client’s needs are.

For example, the client might be a school that wishes to set up a school registration program. So the school administrator might tell the programmer that they need to record students’ data such as name, date of birth, gender, class, parents’ names, address and contact numbers.

PROGRAM DESIGN PHASE
Based on that, the programmer will design a flow chart that represents the needs of the client, which in this case is the school registration program.

CODING PHASE
Once the flow chart is confirmed, the programmer will perform coding.

TESTING AND DEBUGGING PHASE
The school registration program will be tested by the users at the client’s site. In this case, it will be the school office administrators. If there are any errors, the programmer will do a debugging of the program.

They either show up as you type the program code, or if you have turned off the automatic syntax error check, the syntax errors show up when you try to run or compile the program.


DOCUMENTATION PHASE
After this, the programmer will complete the documentation for the program; this includes the user manual, a clear layout of the input and output records and a program listing.

Form 5 : Logical Operators, Flow Chart, Control Structure

FUNCTIONS OF LOGICAL OPERATORS

Logical operators are notations that tell the computer to perform logical operations.
Examples of Logical operation are: AND, OR, and NOT.
Logical operator compares 2 conditions and returns a TRUE or FALSE value.


AND operator
Notice that truth value of X AND Y is True ( 1 ) if only both X and Y are True ( 1 ).
Else it is false ( 0 )


OR operator
Notice that truth value of X OR Y is only True ( 1 ) if either X or Y are True ( 1 ) or both X and Y are true ( 1 )
Else it is false ( 0 )


NOT operator

The diagram shows the truth table of NOT operator NOT X is the negation of X, it is essentially the 1's complement operation.
Notice that truth value of NOT X is True
( 1 ) when X is False and vice versa.


FLOW CHART
Let’s identify some of the main elements in the flow chart. We have five main elements in a flow chart.

Flowline and arrowhead use to connect symbols and indicate the sequences of operation.
Input or output shows either an input operation (e.g. an INPUT from the
user) or an output operation (e.g. PRINT some messages).

Process shows a process to be carried out (e.g. calculation).
Decision shows a decision (or choice) to be made. The program should continue along one of two routes (e.g. if...else).

A flow chart is a diagram using symbols to show the step-by-step sequence of procedures in a program. A flow chart describes the logic and program flow of a computer program graphically.


CONTROL STRUCTURES

Control structure is a structure of statements in programming that allows
the programmer to control the flow of a program.
Control structure can be divided into sequence, selection and repetition control structures.


SEQUENCE CONTROL

Sequence control refers to the linear execution of codes within a program. In sequence control, the statements are executed one by one in consecutive order.
In sequence control, the statements are executed one by one in consecutive order.

This program will request the user’s date of birth and then request today’s date, calculate the age and finally will print the user’s age.
It will execute statement 1 followed by statement 2 and any following statements.


SELECTION CONTROL

There are times when you want your program to make a decision based on the situation given.
For example, a program that stores student’s marks may respond differently to different marks.
Or maybe a simple mathematical program will display its result as odd or even, based on the result.
Selection control enables the programmer to assign different events for different situations.

An example of selection control is “If...Then...Else” statement. The basic pseudo code for “If...Then...Else” statement is as follows.
A student requests her service hours in a library from the program, the
program will then check whether her service hours are more than/equal to 30 or not.

If the service hours are over or equal to 30, the program will print a message, “Thank you for your service”.

If the service hours are lower than 30 then the program will print a message, “Please continue to serve in the library”.

Form 2 (ICTL) : NETWORKS

COMPUTER NETWORKS :
A computer network is a system of interconnected computers and peripheral devices. For example, it may connect computers, printers, scanners and cameras.
Using hardware and software, these interconnected computing devices can communicate with each other through defined rules of data communications. In a network, computers can exchange and share information and resources.
A computer network may operate on wired connections or wireless connections.
When two or more networks are linked or connected and are able to communicate with one another using suitable hardware and software, it is called an internetwork.

BENEFITS OF COMPUTER NETWORKS ;
1. Computer network can share devices
2. Can share data and information
3. Can share internet access

COMPUTER NETWORKS DEVICES :
1. Switch
2. Router
3. NIC (Network Interface Card)
4. Hub
5. UTP cable (wired)
6. Wireless

COMPUTER NETWORKS :
1. LAN
2. MAN
3. WAN

DIFFERENCE OF COMPUTER NETWORKS :
1. Cost : LAN - low
MAN - high
WAN - higher
2. Network Size : LAN - small
MAN - larger
WAN - largest
3. Speed : LAN - fastest
MAN - slower
WAN - slowest
4. Number of computers : LAN - smallest
MAN - large
WAN - largest

NETWORKS TOPOLOGY :
1. Star topology
A star topology consists of a central host which acts as the centre, and all nodes connect to the host. A star topology is also known as star network.
A star network must have a host which acts as the centre - can be a server, hub or router.
In a star network, every node will not connect to the neighbouring nodes.
Every node must connect to the host in order to communicate.
The host will control the flow of communication in the network.

Advantages of star topology :
a) It is easy to implement. You only add nodes to the host.If one of the nodes fails, the star network can still function as long as the host is working.
b) The failure of a node does not affect the entire LAN. If the host fails, the network will fail to function.
c) There are no disruptions to the network when connecting or removing devices.
d) The network can be extended by adding new devices to the host or nodes.
e) Troubleshooting is easy when the host fails. Simply repair or replace the host and the network will continue to function.

Disadvantages of star topology :
a) If the host fails, the entire LAN will be affected.
b) Network speed decreases when the number of nodes increases.
c) Troubleshooting is difficult when one of the nodes fails.
d) A host must be installed to control the network.

2. Ring topology
A ring topology consists of all computers and other devices that are connected in a loop. Ring topology is also known as a ring network.

Advantages of ring topology :
a) Troubleshooting is easy when one of the nodes fails.
b) Repair or remove the failing nodes and the network will continue to function.

Disadvantages of ring topology :
a) Implementation is difficult. Network administrator has to terminate the entire network to install a new node between existing nodes.
b) A failing node will affect the entire LAN. If one of the nodes fails, the network will fail to function.
c) Network speed decreases when the number of nodes increases.

3. Bus topology
ABus networks are very common in Local Area Networks (LAN). A bus network must have a common backbone (the central cable) to connect all devices. A bus topology is also known as a bus network.

Advantages of bus topology :
1. Easy implementation. New devices can be added to the backbone or to the existing nodes.
2. Failure of a node doesn't affect the entire LAN.
3. No disruptions to the network when connecting or removing devices.
4. Network can easily be extended, by adding new devices to the backbone or existing nodes.

Disadvantages of bus topology :
1. If the backbone fails, the entire bus network will be affected.
2. Network speed decreases when the number of nodes increases.
3. Troubleshooting is difficult when one of the nodes fails.

Form5 ik : Constants & Variables & Data Type

5 Basic elements in programming.

1. Constant.
2. Variable.
3. Data Type.
4. Operators.
5. Control Structures.

Constants
Constant is a data container that stores information. The value will never change (remains constant) at any time during the course of a program.

Declare is the official term used in programming to announce to the program
the condition of statement in programming.

Variables
Variable is a data container that stores information. The value inside may change at any time during the course of a program.

DATA EXAMPLES FOR DIFFERENT DATA TYPES

Data type determines the type of data a variable can store, for example a number or a character. Examples of data types are integer, double, string and boolean.

Integer
Integer data type contains any whole number value that does not have any fractional part.
This is how we declare an integer type constant in Visual Basic statement.
This is how we declare an integer type variable in Visual Basic statement.

Double
Any number value that may and could contain a fractional part.
This is how we declare a double type constant in Visual Basic statement.

String
Any value that contains a sequence of characters.
This is how we declare string type constant in Visual Basic statement.

Boolean
Boolean type consists either a True or False value. Programmers usually use it to store status.
This is how we declare a boolean type constant in Visual Basic statement.

Form 2 (ICTL) : PROGRAMMING (copy this note)

PROGRAM

A computer program is a series of organised instructions that directs a computer to perform tasks. Without programs, computers are useless.
A program is like a recipe. It contains a list of variables (called ingredients) and a list of statements (called directions) that tell the computer what to do with the variables.

PROGRAMMING

Programming is a creation of a set of commands or instructions which directs a computer in carrying out a task.

Later these commands or instructions will be compiled and/or interpreted and then transformed to executable instructions that a computer or electronic device can execute or run.

PROGRAMMING LANGUAGE

A programming language is a set of words, symbols and codes that enables humans to communicate with computers.

It is a language used for writing computer programs, that direct a computer to perform computation and to organise the flow of control between mechanical devices.

EXAMPLES PROGRAMMING LANGUAGE

Hundreds of programming languages exist today. Each language has its own standard or rules for writing the commands and/or instructions.

Examples of programming languages are:
BASIC (Beginner’s All Purpose Symbolic Instruction Code)
Pascal
C
Cobol
Smalltalk

Program Development Phases
