Access
A means of approaching, entering, exiting, communicating with, or making use of:
used a browser to access a website; accessed her bank account online.
Authentication
To positively verify the identity of a user, device, or other entity in a computer
system, often as a prerequisite to allowing access to resources in a system.
Connection
A communications link between two points:
Established a connection to the Internet.
Customer
Data
Device
DSL
One that buys goods or services.
Distinct pieces of digital information. Data is usually formatted in a specific way and
can exist in a variety of forms, such as numbers, text, etc. When used in the context
of transmission media, data refers to information in binary digital format.
A device is a unit of physical hardware or equipment that provides one or more
computing functions within a computer system. It can provide input to the computer,
accept output or both. A device can be any electronic element with some computing
ability that supports the installation of firmware or third-party software.
Digital Subscriber Line or Digital Subscriber Loop. Refers to the variety of different
types of Digital Subscriber Line protocols – high-speed data transmission protocols
that are compatible with regular copper telephone wire. DSL is typically used to
provide a continuous, high-speed connection directly to an Internet Service Provider
Home network
Electronic mail. A service that sends messages on computers via local or global
networks.
A local area network (LAN) that connects the PCs in a home and lets users access
the Internet simultaneously, share drives, share files and printers, and play head-tohead multi-player games.
Internet
A network of networks; a group of networks interconnected via routers. The Internet
(with a capital I) is the world's largest internet.
Internet Access
Access to the Internet via a dial-up account via telephone circuit or direct
connection.
Email
IP Address
(IP). The IP part of TCP/IP; the protocol used to route a data packet from its source
to its destination over the Internet.
The unique 32 bit number assigned to each computer connected to the Internet and
used by the TCP/IP protocol to route packets of data to their destinations. The
number is usually written in shorthand "dotted octet" notation in which the 32 bit
address is grouped into four sets of 8 bits. Each of those eight-bit sets is converted
into a decimal number, and the four resulting decimal numbers are written separated
by dots. Most Internet addresses consist of a network portion and a node portion.
The address for a host must be unique on the network. When you connect to a web
server, for example, you may tell your browser to connect to www.mysite.com, but
your computer ultimately has to translate the name to its IP address, 109.208.000.1,
before the connection can be made
Network
A group of interconnected computers, including the hardware and software used to
connect them.
Internet Protocol
Router
At a distance; in communications, referring to a system, application, or device that
must be accessed through a network. Contrast local.
An interconnection device that is similar to a bridge but serves packets or frames
containing certain protocols. Routers link LANs at the network layer. A device that
finds the best path for a data packet to be sent from one network to another. A router
stores and forwards electronic messages between networks, first determining all
possible paths to the destination address and then picking the most expedient route,
based on the traffic load and the number of hops. A router works at the network
layer (layer 3 of the OSI model); a bridge works at the data link layer (layer 2). A
router does more processing than a bridge does. A router can be hardware or a
combination of hardware and software.
Service agreement
A contract between a service provider and a customer that specifies what services
the service provider will furnish
Software
Software is the program or set of programs that tell a computer what to do.
Hardware is the physical part of a computer system; the machinery and equipment.
Vaild
Having legal force; effective or binding
Validated
To declare or make legally valid.
Wireless
Transmission via radio waves or satellite
Remote
