a telephone line.
Network A connection of two or more computers that allows users to share programs, data
files, and hardware devices.
On-line Direct connection of a computer terminal to the files and other equipment controlled

is the most popular business spreadsheet, but there are many clones (programs that are similar
but different in cost or features).

antivirus program should be installed on all computers, used frequently to avoid inadvertently
downloading an invading virus, and continually updated.
