ISP

An ISP (Internet Service Provider) is a company that provides

individuals and companies access to the Internet and other related

services

such as website building and virtual hosting.

LAN

A local area network (LAN) is a group of computers and associated

devices that share a common communications line and typically share the

resources of a single processor or server within a small geographic area

(for example, within an office building).

Latency

The time delay between when the first bit of a packet is received

and the last bit is forwarded.

Link Quality

Indicates the Quality of data being received.

MAC Address

The MAC (Media Access Control) address is a unique

number assigned by the manufacturer to any Ethernet networking device,

such as a network adapter, that allows the network to identify it at the

hardware level.

Mbps

(Megabits per Second) – One million bits per second; a unit of

measurement of the speed of data transmission.

NAT

NAT (Network Address Translation) is the translation of an Internet

Protocol address (IP address) used within one network to a different IP

address known within another network. One network is designated the inside

network and the other is the outside.

Wireless PC Card

Network

A system that transmits any combination of voice, video, and/or

data between users.

NIC (

Network Interface Card) – A board installed in a computer system,

usually a PC, to provide network communication capabilities to and from that

computer system. Also called an adapter.

Packet Filtering

Discarding unwanted network traffic based on its

originating address or range of addresses or its type (e-mail, file transfer, etc.).

PCI (

Peripheral Component Interconnect

)

– A peripheral bus commonly used

in PCs, Macintoshes and workstations. It was designed primarily by Intel and

first appeared on PCs in late 1993. PCI provides a high-speed data path

between the CPU and peripheral devices (video, disk, network, etc.).

There are typically three of four PCI slots on the motherboard. In a Pentium

PC, there is generally a mix of PCI and ISA slots or PCI and EISA slots.

Early on, the PCI bus was known as a “local bus.”

PCI allows IRQs to be shared, which helps to solve the problem of limited

IRQs available on a PC. For example, if there were only one IRQ left over

after ISA devices were given their required IRQs, all PCI devices could share

it. In a PCI-only machine, there cannot be insufficient IRQs, as all can be

shared.

PCMCIA

The PCMCIA (Personal Computer Memory Card International

Association) is an industry group organized in 1989 to promote standards for a

credit card-size memory or I/O device that would fit into a personal computer,

usually a notebook or laptop computer.
