Routine

Routines are instructions written in programming code interpreted to perform a particular task in the course of the program’s operation.

Several routines make up modules. A routine can also be referred to as a procedure, function or subroutine.

Hexadecimal

The hexadecimal (base 16) number system used for Web-page design consists of 16 unique symbols:0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.

For example, the decimal number 15 is equal to the hexadecimal number F. In HTML, an RGB color can be designated by
RRGGBB
with the first two numerals representing the amount of red, the second two the amount of green, and the last two the amount of blue. If you wanted your background to be red, you could write the code for a body background color as
<body bgcolor="#FF0000">
Black is the absence of all color and white is the presence of all color, so in hexadecimal, black is at the bottom of the system (no red, green, or blue:
#000000
and white is at the top (the maximum amount of red, green, and blue:
#FFFFFF

Operator


An expression tells JavaScript what to do with the data it gets, and within each expression are operators and operands. Operands are the data or data types the expression gets, and operators are the shorthand characters that tell the expression what to do with the operand. JavaScript has arithmetic (+,-,*,/), assignment (=), bitwise (&, |), comparison (>, <,), logical (&, ||, !), special (., []), and string (+) operators. Operators are a feature of many programming and scripting languages. At first there were a relatively limited menu of operators to use in JavaScript, but version 1.2 allowed for the support of regular expressions and a group of operators large enough to compare to other scripting languages.

Perl


Practical extraction and reporting language, or Perl, is a scripting language first created by Larry Wall to be used as duct tape for programming with the Unix operating system. Due to its immense power for handling piles of text and, consequently, as a common gateway interface (CGI) scripting language, Perl became very popular among server-side scripters. Perl has a large community of contributing programmers and, what’s more, costs nothing and is free to redistribute. These circumstances have helped Perl evolve from a scripting language used to generate server stats into a language many use for database administration. All along Perl has maintained its zaniness. Most Perl documentation reads as though written by early vaudeville comedians.

PHP


PHP is an open-source scripting language that is embedded alongside HTML to perform interactive functions, such as accessing database information. PHP is similar to Microsoft’s active server page technology, but is used primarily on Linux web servers (or Windows servers with add-on software). An HTML page that has PHP script usually has a “.php” extension. Visit Webmonkey’s Tutorial:PHP Tutorial for Beginners to learn how it works.
