Bit:
A binary digit, which is either -0 or -1 for value, is the smallest unit for data.
Bridge:
An internetworking function that incorporates the lowest 2 layers of the
OSI network protocol model.
Browser:
An application program that enables one to read the content and
interact in the World Wide Web or Intranet.
BSS:
BSS stands for “Basic Service Set”. It is an Access Point and all the LAN
PCs that associated with it.
Channel:
The bandwidth which wireless Radio operates is divided into several
segments, which we call them “Channels”. AP and the client stations that it
associated work in one of the channels.
CSMA/CA:
In local area networking, this is the CSMA technique that combines
slotted time -division multiplexing with carrier sense multiple access/collision
detection (CSMA/CD) to avoid having collisions occur a second time. This works
best if the time allocated is short compared to packet length and if the number of
situations is small.
CSMA/CD:
Carrier Sense Multiple Access/Collision Detection, which is a LAN
access method used in Ethernet. When a device wants to gain access to the
network, it checks to see if the network is quiet (senses the carrier). If it is not, it
waits a random amount of time before retrying. If the network is quiet and two
devices access the line at exactly the same time, their signals collide. When the
collision is detected, they both back off and wait a random amount of time before
retrying.
DHCP:
Dynamic Host Configuration Protocol, which is a protocol that lets
network administrators manage and allocate Internet Protocol (IP) addresses in
a network. Every computer has to have an IP address in order to communicate
with each other in a TCP/IP based infrastructure network. Without DHCP, each
computer must be entered in manually the IP address. DHCP enables the
network administrators to assign the IP from a central location and each
computer receives an IP address upon plugged with the Ethernet cable
everywhere on the network.
