CPU: Central processing unit, or sometimes simply processor, is the
component in a computer that interprets and executes instructions and
data contained in software.
RAM: Random-access memory (primary memory) refers to data
storage formats and equipment that allow stored data in a computer to be
accessed in any order. All computer instructions executed must reside in
RAM.
BIOS: Basic input/output system refers to the software code run by a computer when first powered on. The primary function of BIOS is to
prepare the machine so other
programs stored on various media in the machine can load, execute, and assume control of the computer.
Motherboard: A motherboard, also known as a main board or system board is the primary
circuit board in a
computer. All computer components of the
computer such as CPU, RAM, hard drive, external storage
and expansion cards are
typically attached to the motherboard via ribbon cables,
other cables, and power connectors.
OS: An operating system is the system
software responsible for the direct control and management of
hardware and basic system operations.
Popular OS are Windows 95, 98, XP, Red Hat Linux 8, MAC OS.
Device Driver:
Is a computer program that enables another
program, typically an operating system (OS),
to interact with a hardware device.
Computer Virus: A virus is a self-replicating
program that spreads by inserting copies of itself into other
executable code or documents. Viruses are
one of the several types of malicious software or malware. While viruses
can be intentionally destructive, many other viruses are fairly benign
or merely annoying.
LAN:
A local area network is a
computer network covering a small geographic area, like a home,
office, or small group of buildings such as a college. Most LANs are
most based on switched Ethernet or
Wi-Fi technology running from 10 to
1000Mb/s (megabits per second).
Bluetooth:
Is a specification
for wireless personal area network (PAN). Bluetooth provides a way to connect
and exchange information between mobile devices like PADs, cell phones
etc wirelessly.
WAN: A wide area network is a
computer network covering a
wide geographical area, involving a vast array of computers. The best example of a WAN
is the Internet. WANs are used to connect
(LANs) together, so that users
and computers in one location can communicate with users
and computers in other locations.
WLAN: A wireless LAN uses radio waves
as its carrier - therefore cable are not needed. Areas covered by WLAN
may range from a single room to an entire campus. WLAN backbone network
usually uses cables, with one or more wireless
access points connecting the wireless users to the wired network.
Dial-Up: Dial-up access is an inexpensive but slow form of
Internet access in which the user uses a
modem connected to the computer and a
telephone line to dial the
Internet Service Provider (ISP) in order to
gain internet access.
Broadband: "Broadband" is a high data-transmission rate internet
connection. DSL (telephone line) and
cable modem (cable line) are both popular
consumer broadband technologies. Both technologies typically are capable
of transmitting 256 kilobits per second or
more depending on service requested from ISP.
SOHO: Small Office Home
Office - is a small office or business-at-home
office environment and business culture, usually consisting of 1-10
employees.
VoIP: Voice over Internet Protocol (also called IP Telephony,
Internet telephony, and Digital Phone) is the
routing of voice
conversations over the Internet or any
other IP-based network. Traditional
telephone uses P.S.T.N. (Public Switched
Telephone Network) for analog voice signal carried over
copper wires.
TCP/IP: Two most important protocols in the Internet Protocol Suite: the
Transmission Control Protocol (TCP) and
the
Internet Protocol (IP). Internet Protocol
Suite is a set of communications protocols
that implement the protocol stack on which
the Internet and most commercial networks
run today.
IP Address: An IP address (Internet Protocol
address) is a unique number that devices use in order to identify and
communicate with each other on a network
utilizing the Internet Protocol standard.
Format X.X.X.X where X is a number between 0 and 255. My IP address is:
MyIP.
Phishing: The act of sending an
e-mail to a user falsely impersonalizing an established legitimate
enterprise in an attempt to deceive the user into surrendering private
information that will be used for identity theft. The e-mail directs the
user to a bogus Web site where updating of personal information, such as
passwords, credit card, social security, and bank account numbers is required.
VPN:
VPN provides you a secure channel between your local computer and a
computer at the remote location. The network user can access this from
any part of the world provided internet connection and accessibility to
the resources is available (definition by vptools).
Setting up a VPN.
