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.
