The IEEE 802.11 Standard encompasses the physical layer (PHY) and the
lower portion of the data link layer. The lower portion of the data link layer is
often referred to as the Medium Access Controller (MAC) sub layer.
ISS (Internet Security Services).
A special software application that allows
all PCs on a network access to the Internet simultaneously through a single
connection and Internet Service Provider (ISP) account.
LAN (Local Area Network).
A system of connecting PCs and other devices
within the same physical proximity for sharing resources such as an Internet
connections, printers, files and drives. When Wi-Fi is used to connect the
devices, the system is known as a wireless LAN or WLAN.
MAC (Medium Access Controller).
Every wireless 802.11 device has its
own specific MAC address hard-coded into it. This unique identifier can be
used to provide security for wireless networks. When a network uses a MAC
table, only the 802.11 radios that have had their MAC addresses added to
that network's MAC table will be able to get onto the network.
Mapping.
Assigning a PC to a shared drive or printer port on a network.
NAT (Network Address Translation).
A network capability that enables a
houseful of computers to dynamically share a single incoming IP address
from a dial-up, cable or xDSL connection. NAT takes the single incoming IP
address and creates new IP address for each client computer on the
network. NAT provides a type of firewall by hiding internal IP addresses.
Network name.
Identifies the wireless network for all the shared
components. During the installation process for most wireless networks, you
need to enter the network name or SSID. Different network names are used
when setting up your individual computer, wired network or workgroup.
NIC (Network Interface Card).
An expansion board you insert into a
computer so the computer can be connected to a network. A NIC is a type of
PC adapter card that either works without wires (Wi-Fi) or attaches to a
network cable to provide two-way communication between the computer
and network devices such as a hub or switch. Most office wired NICs
operate at 10 Mbps (Ethernet), 100 Mbps (Fast Ethernet) or 10/100 Mbps
dual speed. High-speed Gigabit and 10 Gigabit NIC cards are also
available. See PC Card.
PC Card.
A removable, credit-card-sized memory or I/O device that fits into
a Type 2 PCMCIA standard slot, PC Cards are used primarily in PCs,
portable computers, PDAs and laptops. PC Card peripherals include Wi-Fi
cards, memory cards, modems, NICs, hard drives, etc.
