Firewall protection
Creative's built-in router provides firewall protection to all the computers on its
network. All these computers share a single public IP address and are assigned
local IP addresses, which are hidden from the outside world. For the external
world, there is no network, only a single device. Creative router blocks any
attempt by any external computer to connect to local resources.
Fragmentation Threshold
The size at which the transmitted data packets are fragmented. The range
extends from 256 to 2346 bytes.
Full duplex
Simultaneous and independent data transmission, between two communicating
computers, in both directions.
Half duplex
A data transmission system where two Notebooks can send and receive data but in
which data transmission can occur in only one direction at a time.
Hexadecimal
A number system with a base of 16. The 16 digits in the hexadecimal system are
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f.
Hub
A device used for connecting nodes in a star topology, that is all the nodes are
connected to a central hub. A passive hub simply organizes the wiring, while an
active hub, besides organizing the wiring, regenerates and retransmits the
signals.
IEEE 802.11
A family of wireless network standards — 802.11a, 802.11b, 802.11e, and
802.11g, out of which 802.11b has won widespread adoption. The original 802.11
standard was first approved in 1997 but was not very successful because it was
relatively slow at 2 Mbps.
IEEE 802.11b
A high-bit wireless network standard that works on the 2.4 GHz band and utilizes
DSSS (direct sequence spread spectrum) technology. It offers data bit rates of up
to 11 Mbps and the range is from 200 to 300 feet for maximum speed.
