Effective use of Teaching Aids

I enjoyed with this lecture because it easy and clearer. Also, I benefited and gained a lot of information about the concept of teaching aids and its importance to us.

 

 Teaching aids support the lesson plan and assist learning. In a legal research skills context, teaching aids use the senses of hearing (through audio tapes, CDs) and sight (through visual aids such as handouts, worksheets/books, overhead transparencies, videotapes and PowerPoint). Research indicates that whilst only about 12% of what we learn comes from hearing, 75% comes from what we see.

Information security

Information security is the process of protecting the availability, privacy, and integrity of data. While the term often describes measures and methods of increasing computer security, it also refers to the protection of any type of important data, such as personal diaries or the classified plot details of an upcoming book. No security system is foolproof, but taking basic and practical steps to protect data is critical for good information security.

Information Security refers to the protection of these assets in order to achieve C - I - A as the following diagram:

C-I-A: Confidentiality:  protecting information from being disclosed to unauthorized parties. Examples:  Personal:  When submitted to a website, your personal data should only be used or accessed exclusively by designated staff in that company for the purposes agreed. No one else should be allowed to use your data for illegal purposes, or view the data out of curiosity. Business: Sensitive information, such as sales figures or client data, should only be accessed by authorized persons such as senior management and the sales team, and not other operations or departments.

Integrity:  protecting information from being changed by unauthorized parties.

                                                              Examples:

	Personal: When submitted to a website, your personal data should not be altered in any way during data transmission, or by the website company. Business: Important documents or figures should not be changed or altered by unauthorized persons without prior notice.

Availability:  to the availability of information to authorized parties only when requested.

Examples:

Personal: You should be able to access and check your personal data kept on a website at any time.

Business: Authorized senior management personnel should be able to access sales figures when needed; or clients should be able to access any of their data kept by the company when they request it.

World Wide Web

The World Wide Web is one of several systems for accessing and distributing information on the Internet. (Other terms for the World Wide Web include the Web, WWW, and W3.) Originated at CERN, a Swiss particle physics laboratory, the Web owes its popularity to its reliance on hypermedia.

Benefits of WWW:

1. Creates a presence:

Many organizations have realized the benefits of establishing a presence online and have effectively addressed objectives by implementing web based applications to improve their business processes. Therefore, a website has the ability to generate awareness to ensure your products are always available to consumers.

 2. Networking:

Organizations and businesses alike strive to establish their presence online. Networking is the best platform to ensure you stay in contact with future clients and companies. Moreover, you can use networking to target a specific audience, thereby increasing revenues.

3. Exchange of business information:

Just like any other technique of advertising, your site can include your business hours, service, e-mail, location and phone for the customers to view. For instance, a hotel might allow clients to make reservations, see what they have as a special menu, and search for vegetarian dishes to help them make informed decisions.

4. It is convenient:

Consumer can easily access your products and services from any part of the world. Your clientele can shop online at the confines of the own homes. Moreover, they can easily search through a large database for particular item instead of having to make long queues at the mall.

5. Improves availability:
You can also make an extra income from your business apart from selling merchandise. For instance, your site can provide consumers with the information they need to buy any item online. The best thing is that this is all done automatically without the need of human resources.

Infringement of personal information still remains the main challenge of the World Wide Web. Your business may face danger when unscrupulous people access your personal information.
