A text editor is a computer program that allows users to enter, edit, store, and print text files. It provides an empty display screen where users can add text line by line. Text editors differ from word processors in that they do not add formatting codes to documents. This makes text editors better for writing code that needs to be compiled since compilers can be confused by formatting codes.

Text Editors:
A text editor is a computer program that lets a user enter, change, store, and
usually print text (characters and numbers, each encoded by the computer and its
input and output devices, arranged to have meaning to users or to other
programs). Typically, a text editor provides an "empty" display screen (or
"scrollable page") with a fixed-line length and visible line numbers. You can then
fill the lines in with text, line by line. A special command line lets you move to a
new page, scroll forward or backward, make global changes in the document,
save the document, and perform other actions. After saving a document, you can
then print it or display it. Before printing or displaying it, you may be able to
format it for some specific output device or class of output device. Text editors
can be used to enter program language source statements or to create
documents such as technical manuals.

A text editor is used to edit plain text files. Text editors differ from word
processors, such as Microsoft Word or WordPerfect, in that they do not add
additional formatting information to documents. You might write a paper in
Word, becauseit contains tools to change fonts, margins, and layout, but Word by
default puts that formatting and layout information directly into the file, which
will confuse the compiler. If you open a .doc file in a text editor, you will notice
that most of the file is formatting codes. Text editors, however, do not add
formatting codes, which makes it easier to compile your code.

networking programs. Utilities can also be applications such as screensavers, font
and icon tools, and desktop enhancements. Some utility programs help keep your
computer free from unwanted software such as viruses or spyware, while others
add functionality that allows you to customizeyour desktop and user interface. In
general, programs that help make your computer better are considered utilities.
