In Perl the lists and arrays are used interchageably Is there any difference between them?
In Perl the two terms are often used as if they’re interchangeable. But to be accurate the list is the data and the array is the variable. You can have a list value that isn’t in an array but every array variable holds a list (although that list may be empty).

DNS can be considered something similar to a phone book. When you move from one location to another, your name stays the same, but your phone number may change. In order to point your name to the new phone number, you must contact the telephone service provider so they assign you the new phone number and update all directory information to reflect you as pointing to this new phone number.
In this way, the IP number can be compared to a phone number: When someone calls http://www.cpwebhosting.net, your ISP looks at the DNS server, and asks “how do I contact example.com?” The DNS server responds: “It can be found at 198.105.232.4”. As the Internet understands it, this can be considered the phone number for the server, which houses the http://www.cpwebhosting.net web site.

Although you will be sent an e-mail notification before your domain expires, you can choose whether to renew your contract with the registrar company manually or automatically. In the automatic mode, your domain name will be renewed for as many years as you specify in your control panel settings. In the manual mode, you would have to enter your control panel and click the Renew Domain link; otherwise the domain name will expire and become unavailable.

In perl programs what is the meaning of using
#!/usr/bin/perl in the first line.
That first line is actually a very special comment. On Unix systems, if the very first two characters on the first line of a text file are “#!”, then what follows is the name of the program that actually executes the rest of the file. In this case, the program is stored in the file /usr/bin/perl.

We cannot say that Perl has a lot of bugs. But it’s a program, and every program has at least one bug. Programmers also know that every program has at least one line of unnecessary source code. By using logical induction, it’s a simple matter to prove that any program could be reduced to a single line of code with a bug.

I m newbie in web hosting field. can anyone tell me what is Domain Aliasing.
Domain aliasing, or domain stacking, is creating additional domain names that would point to the IP of a different domain. For example, if your domain name is cpwebhosting net, you can register another domain name, e.g. cpwebhosting com and have it point to the location of cpwebhosting net. This means, every Internet user who goes to cpwebhosting com will land in cpwebhosting net.

You can also host sites without domain names (the so-called stop-gap domains). When you create a stopgap domain you get no DNS zone, and you cannot use e-mail service. However you will be able to access and manage your site using the instant domain alias you get at signup.
An instant domain alias is an additional web address that gives access to your website when you don’t have a real domain name or when your real domain name is temporarily unavailable. Instant domain aliases are generated randomly based on your provider’s domain name and can’t be changed. To enable or disable access to your website by instant domain alias.

If you want to use MySQL on your dedicated server you can install MySQL by compiling the source code with the options that best suit your needs or by downloading and installing a prebuilt binary.
Or you can ask the CPWebhosting Support team they will do it using the the package management system appropriate to your operating system. You can get both binary and source code at the MySQL web site.

Features like stored procedures, triggers, referential integrity, and SQL unions and subqueries which are there in relational databases are not supported by MySQL. So there are limitations to the environment in which it can be used. But, it is well suited for Web applications.
Recently, MySQL added support for transactions; they are apparently at work now on stored procedures. That is why MySQL is an excellent product and getting better all the time.

Can I Park External Domains In my my web hosting account.
This feature allows you to use H-Sphere DNS server to map IPs to domain names serviced and hosted on other servers (not those of H-Sphere). In this case, a DNS zone is created with a custom DNS A record for the domain name and its IP is entered in the form.
