ICTL-F2 : CYBER LAW

What is Cyber Law?

Cyber law refers to any laws relating to protecting the Internet and other online communication technologies.

NEEDS FOR CYBER LAW

In the recent years, many concerns and issues were raised on the integrity and security of information, legal status of online transactions, privacy and confidentiality of information, intellectual property rights and security of

government data placed on the Internet.

These concerns and issues clearly indicate why cyber laws are needed in online activities.

THE CYBER LAW ACTS IN MALAYSIA

The Malaysian Government has already passed several cyber laws to control and reduce the Internet abuse.

These cyber laws include:

· Digital Signature Act 1997

· Computer Crimes Act 1997

· Telemedicine Act 1997

· Communications and Multimedia Act 1998

Beside these cyber laws, there are three other cyber laws being drafted.

· Private Data Protection Bill

· Electronic Government Activities Bill

· Electronic Transactions Bill

ICTL F2 : 2.4 - Netiquette

Netiquette, is the convention on electronic forums (Usenet, mailing lists, live chat, and Internet forums) to facilitate efficient interaction. Internet phenomena, the concept and its application remain in a state of flux, and vary from community to community. The points most strongly emphasized about USENET, netiquette often include avoiding cross-posting, using simple electronic signatures, and other techniques used to minimize the effort required to read a post. Netiquette guidelines posted by IBM for employees utilizing Second Life in an official capacity, however, focus on basic professionalism, maintaining a tenable work environment, and protecting IBM's intellectual property. Similarly, some Usenet guidelines call for use of unabbreviated English while users of online chat protocols like IRC and instant messaging protocols like SMS often encourage trends in the opposite direction.

ICTL - F2 : 2.3 - Search Engine & Function

Search Engine :

A search engine is an information retrieval system designed to help find information stored on a computer system. Search engines help to minimize the time required to find information and the amount of information which must be consulted, akin to other techniques for managing information overload.

The most public, visible form of a search engine is a Web search engine which searches for information on the World Wide Web.

Function :

Search engines provide an interface to a group of items that enables users to specify criteria about an item of interest and have the engine find the matching items. The criteria are referred to as a search query. In the case of text search engines, the search query is typically expressed as a set of words that identify the desired concept that one or more documents may contain

Examples :

Yahoo

Google

ICT - F5 : Extra Notes 3

VOICE OVER INTERNET PROTOCOL (VoIP)
Protocols used to carry voice signals over the IP network are commonly referred to as Voice over IP or VoIP. VoIP is one of the Internet technologies that allows a user to make telephone calls using a broadband Internet connection instead of a regular (or analog) phone line.
VoIP is a method for taking analog audio signals and turning them into digital data that can be transmitted over the Internet.

VoIP SERVICES

There are three different VoIP services in common use today. They are Analog Telephone Adapter (ATA), IP Phones and computer-to-computer.

ANALOG TELEPHONE ADAPTER (ATA)
The simplest and most common way is through the use of a device called an Analog Telephone Adapter (ATA). The ATA allows you to connect a standard phone to your computer or your Internet connection for use with VoIP.

The ATA is an analog-to-digital converter. It takes the analog signal from your traditional phone and converts it into digital data for transmission over the Internet.
Skype, one VoIP provider, offers free calling locally and between members, and inexpensive long-distance calls to other numbers.

IP PHONES
IP Phones look just like normal phones with a handset, a cradle and buttons. IP Phones have an RJ-45 Ethernet connector instead of the standard RJ-11 phone connectors.
IP Phones connect directly to your router and have all the necessary hardware and software onboard to handle the IP Call. Soon, WiFi IP phones will be available, allowing subscribing callers to make VoIP calls from any WiFi hot spot.

COMPUTER-TO-COMPUTER
Computer-to-computer is certainly the easiest way to use VoIP. Devices needed to place a computer-to-computer Internet telephone call:

Software, a microphone, speakers or headphones, a sound card and an Internet connection preferably a fast one like you would get through a cable or DSL modem.
Except for your normal monthly ISP fee, there is usually no charge for computer-to-computer calls, no matter what the distance.

ADVANTAGES OF VoIP

As VoIP is digital, it may offer features and services that are not available with a traditional phone. If you have a broadband Internet connection, you need not maintain and pay the additional cost for a line just to make telephone calls.

With many VoIP plans you can talk for as long as you want with any person in the world. You can also talk with many people at the same time without any additional cost.

DISADVANTAGES OF VoIP
Some VoIP services do not work during power failures and the service provider may not offer backup power.
Not all VoIP services connect directly to emergency services. VoIP providers may or may not offer directory assistance or white page listings.
As VoIP uses an Internet connection, it is susceptible to all the problems normally associated with home broadband services.

Phone conversations can become distorted, garbled or lost because of transmission errors. Some kind of stability in Internet data transfer needs to

be guaranteed before VoIP could truly replace traditional phones.

VoIP is susceptible to worms, viruses and hacking, although this is very rare and VoIP developers are working on VoIP encryption to counter this.

INTERNET SERVICES :
BLOGGING

A blog (web log or weblog) is one of the popular activities on the Internet. Most of these blogs are publicly shared and the authors frequently update the content on a regular basis.
A blog is usually referred to the text produced by the author about his or her thoughts, experiences or interests.
A blog is usually referred to the text produced by the author about his or her thoughts, experiences or interests.
The world of blogging is referred as blogosphere. Another new term is the blogonomics, which refers to people using the blogosphere to generate money.
The posts to a blog are usually arranged in this order, the most recent entries will always be on top of the journal.

To write a good blog, you need to remember these principles:

use a consistent writing style and appropriate tone for your subject
post often, though your posts are short
allow your readers to eave you comments on your posts

If you would like to search some blogs, you can visit blogarama.com

(www.blogarama.com), which categorises blogs into directories. Following are several top blogging resources you should check out:

Blogger (www.blogger.com) - owned by Google, one of the free and easiest to maintain blogging tool.
TypePad (www.typepad.com) - the blog tool that provides more functionality for a minimal fee.
Movable Type (www.movabletype.org) - if you have your own domain site and want to put several blogs together, this is the best choice
Wordpress (wordpress.org) - an open source blogging tool that needs a bit of coding to make your blogs more interesting

WORLD WIDE WEB (WWW)

The World Wide Web or the Web consists of a worldwide collection of electronic documents.

Each electronic document on the Web is called a web page which can contain text, graphics, audio and video.

These pages are written in Hypertext Markup Language (HTML).

Every website has an address or Uniform Resource Locator (URL). The URL is formed by the protocol, domain, directory and the document name.

EMAIL

An electronic mail or email is the transmission of messages and files via a computer network.

A user utilises an email program to create, send, receive, forward, store, print and delete email messages.

Some emails are called web-based email like Yahoo Mail and Hotmail.

THE INTERNET RELAY CHAT (IRC)
The Internet Relay Chat (IRC) is a system for chatting that involves a set of rules and conventions, and client/server software.
A chat is a real-time typed conversation that takes place on a computer. A chat room is a location on an Internet server that permits users to chat with each other.
Anyone in the chat room can participate in the conversation, which usually is specific to a particular topic.

SEARCH ENGINES
Search engines are special websites on the Internet to help you find information you need. Different search engines will serve different purposes, for example:

Google Scholar (http://scholar.google.com/) is for searching authoritative and scholarly sites.
Google (http://www.google.com/) is for searching valuable or relevant sites with rankings.
Yahoo News (http://dailynews.yahoo.com) is for searching opinions on current issues.
Wikipedia (http://www.wikipedia.org/) it is an open source for encyclopedia

ICTL - F2 : 1.3 - TOPOLOGY

BUS TOPOLOGY
In communications technology, you think of a bus as a common “highway” on which data is transmitted. A bus refers to the main physical pathway or central cable where all other devices are connected to it. Like a major motor highway, all traffic flow will be affected if this main “road” is broken.

A bus topology consists of a single central cable to which all computers and other devices connect. A bus topology is also known as a bus network.

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.
A ring network can be found in Local Area Networks. In a ring network each node
directly connect to two neighbouring nodes.
A server may exist in a ring network, but it will not connect to all the nodes in the network.The server, like other nodes, will only communicate to its two neighbouring nodes.

STAR TOPOLOGY
In the early days of computer networking, all computers were connected to a centralised mainframe computer.
All resources and management of information were centred in this main computer.
The idea of a centralised mainframe computer is where the basic concept of a star topology comes from.

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.

ICT - F4 : 3.0 - NW & COMM & DEVICES & TYPES & CLIENT SERVER

3.0 : COMPUTER NETWORK AND COMMUNICATION

COMPUTER NETWORK ?

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.

COMMUNICATIONS ?

Communications is about the transfer of information from a sender, across a distance, to a receiver.Using electricity, radio waves or light, information and data in the form of codes are transmitted through a physical medium such as wire, cable, or even the atmosphere. The information that is transmitted (sent) can be text, voice, sound, video, graphics and images, or a combination of all these, which we call multimedia.

We transmit information or data by using two types of signals, namely analog and digital. Computers communicate with digital signals. The older forms of communications technology, such as telephones and radios, use analog signals.

Therefore, in order to make communications possible from computers, across telephones and radios and back to computers and other digital devices again, there must be a signal translator, which we call – a modem.
The modem, which is short for modulator or demodulator, converts digital signals into analog and back again into digital signals for information to move across the telephone line.

In order for a network to properly operate, two categories of network communications components are needed; ‘Hardware’ and ‘Software’. Computers, hub, switch, router, network interface cards and both wired and wireless communications media fall under the ‘Hardware’ category. Operating systems and applications fall under the ‘Software’ category.

NETWORKING DEVICES ?

1. NIC (Network Interface Card)
2. Wireless Network Interface Card
3. Internal Modem
4. External Modem
5. Hub
6. Switch
7. Router
8. Wireless AP (Access Point)

TYPES OF NETWORKS
Three types of networks:
LAN - the email system within the school lab in SMK KL
MAN - the email system within KL city
WAN - the email system between KL and London

CLIENT/SERVER ?

A client/server network is a network in which the shared files and applications are stored in the server but network users (clients) can still store files on their individual PCs.
A server is a computer that shares information and resources with other computers on a network. A client is a computer which requests services or files from a server computer.

CLIENT ?

The client computers are computers on the network that rely on the server for its resources and services.
Client computers send requests to a server for resources or services to perform their job. For example, a client computer can send a request asking permission to use the printer attached to the server, to print a document.
Usually a client computer has to log onto the network using a user name and password to use the server’s resources and services.

For example, you have to be a TMnet or Jaring member to use the internet service. You need to logon to TMnet or Jaring’s server by sending your username and password.

SERVER ?

A server is sometimes called a host computer. A server is a computer that provides services to other computers called clients. A server controls access to the hardware, software and other resources on the network.
It provides a centralised storage area for programs, data and information.

PEER-TO-PEER NETWORK ?

Peer-to-peer or P2P network is a network with all the nodes acting as both servers and clients. A PC can access files located on another PC and can also provide files to other PCs.
All computers in the peer-to-peer network has equal responsibilities and capabilities to use the resources available on the network.
With peer-to-peer network, no server is needed; each computer in the network is called a peer.
