You're talking about a feature most commonly called "MAC address filtering" - it takes advantage of the fact that each networked device must have a physical address - the MAC address - even before an IP/IPX address (or any other, higher-layer address) is assigned to it, or even before any communication commences.
The MAC address is composed of manufacturer ID (assigned externally) and manufacturer-specific information (assigned internally). MAC addresses are only "visible" within their physical networks, as they are used to identify physical paths to form physical connections from point A to point B (from hop to hop). While these may occasionally coincide within a network (be the same), the probability of this occurring is extremely rare in most cases.
This type of security isn't bulletproof, however - a network device can have its behavior altered so that it reports a MAC address different from the one assigned to it by its manufacturer (most commonly routers have this option, so that they can be connected to cable modem networks employing this kind of user control), but it is often a good first step towards controlling outside access to a wireless (or any network) access point.
Two most common types of configurations are: blacklist mode (anything is allowed, except for what is on the blacklist) and whitelist mode (everything is blocked, except for what is on the whitelist). The particular method you are referring to is MAC address whitelisting.
What is the meaning of shttp and fttp?
SHTTP means Secure Hypertext Transmission Protocol (aka Secure-HTTP).
SHTTP is an extended version of HTTP providing security through encryption. SHTTP encrypts data transfers, but does not authenticate the client. The responsibility for authentication remains with the website (i.e. the responsibility for determining whether the visitor should be shown the information in the first place).
FTTP means Fiber to the Premises. This term is used in several contexts: as a blanket term for both FTTH and FTTB, or where the fiber network includes both homes and small businesses.
Fiber to the x (FTTx) is a generic term for any broadband network architecture that uses optical fiber to replace all or part of the usual metal local loop used for last mile telecommunications. The generic term originated as a generalization of several configurations of fiber deployment (FTTN, FTTC, FTTB, FTTH...), all starting by FTT but differentiated by the last letter, which is substituted by an x in the generalization.

What is a trusted site to give free mp4 videos?
I'm not really sure what you're asking.
If you want a site to get mp4 videos off, mp4 videos can be downloaded from Youtube. Put this in your bookmarks and click it while viewing a Youtube video to get the mp4 file:
javascript:if(document.location.href.match(/http:\/\/[a-zA-Z\.]*youtube\.com\/watch/)){document.location.href='http://www.youtube.com/get_video?fmt='+(isHDAvailable?'22':'18')+'&video_id='+swfArgs['video_id']+'&t='+swfArgs['t']}
If you want a site that you can upload a file and let others download it, iFile it is a good site to use:

What are root keys in association with digital certificates?
Digital certificates are verified through the use of another certificate, creating a chain of certificates that ends with the root certificate
The issuer of a certificate is called a certification authority (CA). The owner of the root certificate is the root certification authority.
Incapsula is a company that was founded in 2009, which developed a unique cloud-based, service that makes websites safer, faster and more reliable.
Incapsula provides websites of all sizes with security and performance capabilities that so far, have only been available for very large Internet websites. It takes 5 minutes to upload the website to the service and it's free for small websites and offers a very attractive price for SSL and big websites, on a monthly subscription base.
They provide what's called a WAF (Web Application Firewall) that protects the website from threats, and also provide a network of servers to speedup the delivery of the site an different performance monitoring and analytics services to provide very good insights on how to improve the delivery of the website.
As far as I understand, Incapsula was spun out and is financially backed by Imperva, a leading provider of data security solutions.

The letters are called "CAPTCHA".
I believe there are different levels of cheating. Some people think cheating is cheating. I don't think a little flirting hurts, but keep in mind you don't know who you are flirting with. You could be flirting with your "mate" and not even know it. Personally, I don't flirt online...I like to see what I'm messing around with. Be careful.
Is there a virus that makes a computer beep on loading?
Most computers beep on loading just as they're powering up. If you find it bothersome, turning down the volume before rebooting should help.
additional information:
Something such as that would require a change of the computer bios settings. Most malware would not change something like that. If your computer use to not do that it is possible (however unlikely) that your computer was attacked. What would be more likely is that someone you know and trust thought it would be funny to do this to you. If this is the case than it is nothing but an announce.
