Risks of File-Sharing Technology

What is file sharing?

File sharing involves using technology that allows internet users to share files that are housed on their individual computers. Peer-to-peer (P2P) applications, such as those used to share music files, are some of the most common forms of file-sharing technology. However, P2P (Peer 2 Peer) applications introduce security risks that may put your information or your computer in jeopardy.

Understanding Voice over Internet Protocol (VoIP)

 What is voice over internet protocol (VoIP)?

Voice over internet protocol (VoIP), also known as IP telephony, allows you to use your internet connection to make telephone calls. Instead of relying on an analog line like traditional telephones, VoIP uses digital technology and requires a high-speed broadband connection such as DSL or cable. There are a variety of providers who offer VoIP, and they offer different services. The most common application of VoIP for personal or home use is internet-based phone services that rely on a telephone switch. With this application, you will still have a phone number, will still dial phone numbers, and will usually have an adapter that allows you to use a regular telephone. The person you are calling will not likely notice a difference from a traditional phone call. Some service providers also offer the ability to use your VoIP adapter any place you have a high-speed internet connection, allowing you to take it with you when you travel.

Understanding Software Patches

What are patches?

Similar to the way fabric patches are used to repair holes in clothing, software patches repair holes in software programs. Patches are updates that fix a particular problem or vulnerability within a program. Sometimes, instead of just releasing a patch, vendors will release an upgraded version of their software, although they may refer to the upgrade as a patch.

Avoiding Copyright Infringement

 

How does copyright infringement apply to the internet?

Copyright infringement occurs when you use or distribute information without permission from the person or organization that owns the legal rights to the information. Including an image or cartoon on your website or in a document, illegally downloading music, and pirating software are all common copyright violations. While these activities may seem harmless, they could have serious legal and security implications.

How do you know if you have permission to use something?

If you find something on a website that you would like to use (e.g., a document, a chart, an application), search for information about permissions to use, download, redistribute, or reproduce. Most websites have a "terms of use" page that explains how you are allowed to use information from the site. You can often find a link to this page in the site's contact information or privacy policy, or at the bottom of the page that contains the information you are interested in using.

Understanding Bluetooth Technology

 

What is Bluetooth?

Bluetooth is a technology that allows devices to communicate with each other without cables or wires. It is an electronics "standard," which means that manufacturers that want to include this feature have to incorporate specific requirements into their electronic devices. These specifications ensure that the devices can recognize and interact with other devices that use the Bluetooth technology.

Many popular manufacturers are making devices that use Bluetooth technology. These devices include mobile phones, computers, and personal digital assistants (PDAs). The Bluetooth technology relies on short-range radio frequency, and any device that incorporates the technology can communicate as long as it is within the required distance. The technology is often used to allow two different types of devices to communicate with each other. For example, you may be able to operate your computer with a wireless keyboard, use a wireless headset to talk on your mobile phone, or add an appointment to your friend's PDA calendar from your own PDA.
