applet
A Java program, which is linked into an HTML
document, then retrieved and executed using a Web browser.
program
A series of instructions executed by the computer, one
after another.
syntax
The syntax of a computer language specifies how words and
symbols can be combined into valid programs. Another word for syntax
is grammar.
semantics
The semantics of a properly formed program statement
describes the meaning of the statement in plain English and how
it will be interpreted by the computer when it is executed.
comments
Most programming languages provide a mechanism that allows
a programmer to embed documentation directly into a program. Comments
provide additional information and explain special processing. All
text within a comment is for the benefit of the human audience, and is
ignored by the computer.
debugging
Debugging is the removal errors, or bugs, from a computer
program. It may take several attempts before all bugs are found and
eradicated, and its even possible to introduce new bugs while trying
to fix the old ones!
hardware
The tangible components of a computer system, such as the
keyboard, monitor, and circuit boards.
software
Programs and data.

pseudocode
Pseudocode is an informal language that helps programmers
develop algorithms for solving problems. The steps in a pseudocode
program are expressed in everyday English. Such programs are not
actually executed on computers. Each step in a pseudocode program
must be translated into one or more steps in a computer language
before the program can be executed.
design
The plan for implementing a program, sometimes expressed using pseudocode.
