Addon domain -:
An addon domain allows you to reach a subdomain when entering the name of the addon domain into a browser.

For example, if domain2.com is an addon domain on sub.domain.com, going to http://www.domain2.com in a browser will bring up sub.domain.com (domain.com/sub).

Parked domains -:
A parked domain allows you to reach your domain when entering the name of the parked domain into a browser.

For example, if domain2.com is parked on domain.com, going to http://www.domain2.com in a browser will bring up domain.com.
Redirects -:
Redirects allow you to make a specific web page redirect to another page and display the contents of that page. This way you can make a page with a long URL accessible by a page which has a shorter and easier to remember URL.

For example: Since http://www.domain.com/new/data/access.html is hard to remember, you can make http://www.domain.com/access.html redirect to the other URL.

All DNS records have a TTL property, specifying the amount of time other DNS servers and applications are allowed to cache the record.

When a DNS record is stored in the cache of a DNS server, the record’s TTL is continuously reduced as time go by, and when the TTL finally reaches zero the record is removed from the cache.

When deciding on the TTL, you need to consider how often the record will be changed.
Because of caching, changes to a DNS record will not reach the entire network until the original TTL has expired - a good reason for setting a short TTL.
But caching helps reduce network traffic. The longer the TTL, the longer the record will live in other DNS server caches around the world, and so fewer requests to the original DNS server are needed - a good reason for setting a long TTL.

Explanation of virus:

1) Virus is a little program that its activity can destruct/destroy
some files and a computer system. If you don’t open this program, it still
inactive and could not destroy anything.

2) The virus program brought to you by an email as attachment. It
has a server itself (virus server). Virus file attachments cannot go to
another email, such as an email was sent by user (netter), member, moderator etc then to be as their attachment. It must be brought to you by email itself,
that we called VIRUS EMAIL / SPAM.

3) VIRUS EMAIL would be sent by any email address of any account, that
they found and cracked from some mailbox or address-book of users from anywhere.
So that why the virus email looks like was sent by our friend, our member,
our moderator etc….. even might be able by email address yourself.

4) To identification of virus attachment:
it has a small size ( 181-185 KB )
it has extension file name such as below (don’t open it):
*.scr
*.clp
*.pif
*.bat
*.exe
*.com
*.txt
*.doc
*.lhz
*.rhz
and some time it’s compressed by *.zip file.
Also by the fake name HotMovie.MPEG_

_________scr.
Actually that file is virus file with extension .scr

5) You could understand an email virus from their SUBJECT,
most of them contains an amazing statement or unusual word,
such as the following examples (don’t open it):
Hi
Pictures.
Weah ^_^ :))
Hokki=)
ello!=))
Hello -:))
Hey, dude, it’s me ^_^

that your account still active.

BEWARE it’s dangerous.
*** If one of your file has infected by virus, it will change into function
as a virus and might could infected all of files in your hard disk.
*** Don’t reply or open virus email.

Link building is one of the most important aspects of Search Engine Optimization. Since every search engine relies upon backlinks to help determine the relevancy score of a particular Web Site, it is usually imperative for a Web Site owner to concentrate on gaining quality backlinks, even though the weight that different search engines give to backlinks may vary greatly.

One way links are given more importance than reciprocal links but in order to get the one-way links, someone has to be willing to give them out. What happens is in the pursuit of achieving the precious one-way links, people have become stingy by not providing with their own links to others.

Linking is an important aspect on the Internet. The purpose of the InterNet is creating a huge web of all of the sites on it, connected to one another. Search engine spiders rely upon this web of networked sites to be able to index them, and Google does not penalize sites for linking to like sites. Contrary to current and popular belief, most search engines in fact have favorable views of a website that links to similar Web Sites. In a way, being greedy with links is like missing the whole purpose of connectivity. the purpose of links is to connect the sites together, and not just to boost the PageRank.

The idea that linking to other sites with some of the same types of information is somehow going to bring a Web Site down a the PageRank is wrong. In natural, organic SEO strategies, people should still be focusing first on what their audience wants, then secondarily upon what the search engines are looking for.

Semi Dedicated Hosting is basically Dedicated Hosting, except for the server which is shared between a very limited number of users. In Semi Dedicated Hosting, the no. of users per server is kept between 2-6 users depending on the traffic and resource usage. Each user on a Semi Dedicated Server has the same tech support as he would have on a Dedicated Server. Semi Dedicated Hosting is suitable for users who want more power than what virtual accounts offer, but aren’t quite ready to move on to a Dedicated Server. By choosing a Semi Dedicated Server you are on a machine where you have access to a large portion of the resources, allowing you to run more traffic intensive websites as well as more complex scripts and software. You also get more control over your servers because they are no longer limited by the virtual Web Hosting control panel and you are free to have the server tweaked exactly to your liking. Semi Dedicated Hosting is the perfect intermediate step between migrating from virtual to Dedicated Server.

A Dedicated Server is dedicated only to a single user and it is setup according to the user’s preference. With Dedicated hosting you don’t need to share your server with anyone. In Dedicated hosting you get your own hosting server for your website instead of having to share a server with others, which could accommodate several websites. The benefit of using Dedicated hosting is that your website performance will not be affected by high traffic websites that would have been sharing your servers bandwidth. Usually a Dedicated Server is used by the companies or individuals who run very high traffic sites and need a large amount of bandwidth and consistent performance.
