specific file.
Peer to peer A network in which network resources are shared among
the workstations
Compression The process whereby a folder or file is manipulated so
that the size is reduced.
CrossTalk When TWO cables magnetic fields influence and disturb
each other
Runtime An error that occurs when the program is running.
Modular design Computers are assembled from a variety of parts to
make functional working unit.
A device driver A device driver is software that contains a set of
instructions that command a computer’s operating
system on how to communicate with the hardware so
that it can function properly. Device drivers allow
communication between the operating system and all
the devices, such as the mouse, keyboard, printer, etc.
The importance of • Programs need to be updated to add new
running updates features
• to fix ‘bugs’
• to deal with new threats in the case of anti-virus
Protocol A network protocol is an established set of rules that
determine how data is transmitted between different
devices in the same network. Examples:
• HTTPS: site is secure
• FTP: File Transfer Protocol / to download large files
• SMTP: Simple Mail Transfer Protocol / to send
emails
BITS AND BYTES You can combine several bits (0s and 1s). If you combine
8 bits together, it is called a ‘‘byte’’. A byte can
represent any number between 0 (represented in bits as
00000000) and 255 (represented in bits as 11111111).
Data Data is unprocessed facts (usually unorganized).
Information Information is processed data. (useful)

Anti-virus A computer program that scans computer files for viruses
and
eliminates them.
Firewall Hardware or software that monitors the traffic between a
computer and the Internet, to safeguard against
breaches in security.
Trojan A form of malware disguised as a useful program, but in
reality, designed to do harm.
• Be careful when downloading free programs from
the internet such as free games and other
programs
Backup Creating a backup 'image' of the entire hard drive,
including
all data and programs, to be used for re-installation in
the case of complete hard drive failure. When data is lost
due to theft or a disaster backed up data can be
reinstalled, and the system can be up and running again.
Phishing Attempts from people, generally employing e-mail, to
direct other
people to fake websites, where they are tricked into
releasing personal information (e.g. passwords); then
using these details to commit identity theft and fraud.
