version
A particular issue or
release of a hardware or software product. Version numbers are
generally represented by an integer (a whole number) combined
with a decimal number (for example 3.2). Successive releases
of a program are assigned increasingly higher numbers. Major
releases are reflected with whole number increments; minor
releases with decimal increments.
When discussing software
versions, an "x" is often used after the version integer to
designate a range of minor releases. For example, Internet
Explorer 4.x refers to all minor releases of Internet Explorer
4.
virus
An intrusive program that infects computer files by
inserting copies of itself in them, thereby causing the files
to be "infected." When the infected file is then loaded into
memory, the virus can then infect other files, and so on.
Viruses often have damaging side effectsùsometimes
intentionally, sometimes not. For example, some viruses can
destroy a computer's hard disk or take up memory space that
could otherwise be used by programs.
Visual
Basic
A high-level, visual-programming version
of Basic. Visual Basic was developed by Microsoft for building
Windows-based applications.
