MAC Address VS. IP Address

Tue, 17 Apr 2012 09:03:41 -0400

A similarity between them is that they are both used when information needs to travel between networks and routers.

(http://www.infocellar.com/networks/ip/mac-vs-ip.htm)

A difference is that an IP Address is assigned by the internet provider and the MAC Address by the hardware manufacturer.

MAC Address in security

Tue, 17 Apr 2012 09:03:38 -0400

MAC Addresses can be used a security measure for your WLAN. All you have to do is enable MAC filterin. What this means is that the administrator of the network must enter in the router a list of the MAC Addresses of the devices allowed in the WLAN. Like this, whenever an unlisted device tries to access the network, the router will reject it.

Lack of MAC Address Protecion

Tue, 17 Apr 2012 09:03:34 -0400

A way of getting your MAC Address hacked is by agreeing to let a piece of software to change it. This is usually requested by a hacker and you he/she will now have access to your computer. Plus, it will probably prevent you from having access to your own WLAN because your MAC Address will no longer appear in the allowed list. So, never allow a third party program to alter any of your system settings.

High-level software agreement issues - Conceptual Map

Interface for hearing impaired people

Mon, 12 Dec 2011 10:15:23 -0500

The ideas of an interface that would help them include putting sound louder in the case that they are not completely deaf. Also, it would be quite useful to replace sound feedback by display feedback. And something that actually quite old is the use of subtitles.

Interface for movement impaired people

Mon, 12 Dec 2011 10:12:18 -0500

This is a technology that is still being developed but what is expected to work for these people is voice command. Instead of using a mouse to select items or a keyboard to type, the computer must respond entirely to voice commands. The problems for this technology is that voice differs a lot regarding volume, tone, pitch, etc. These modifications are often confusing to the system
