Thus, baud rate is the speed the digital signal pulses travel.
Bit Rate
The transmission rate of binary symbols (.0. and .1.)
Bit rate is equal to the total number of bits transmitted in one second.
DHCP (Dynamic Host Configuration Protocol)
A protocol that automatically assigns the dynamic IP addresses to devices on a network. With
dynamic addressing, a device can have a different IP address every time it connects to the
network and simplifies network administration because the software keeps track of IP
addresses rather than requiring an administrator to manage the task. When a device newly
added into the network, a dynamic IP address will be assigned to that device. Many ISPs use
dynamic IP addressing for dial-up users.
DNS
Domain Name Server is a server that translates domain names into IP addresses. A domain
name is alphabetic and is meaningful for human to remember and use. However, the Internet
routing is based on IP address. So, when you enter a domain name, the DNS server will
translate the domain name into the corresponding IP address. For example, the domain name
www.example.com might be translated to 198.152.212.140
DSSS (Direct-Sequence Spread Spectrum)
DSSS is a transmission technology used in WLAN transmissions to increases the signal's
resistance to interference. At the sending station, the data signal is combined with a higher
data rate bit sequence to generate the DSSS signal. At the intended receiving station, the
DSSS signal is recognized as valid signal, however, for an unintended station, the DSSS
signal appears as low power wideband noise and is rejected (ignored).
The bit sequence is a redundant bit pattern for each bit that is transmitted. If one or more bits
in the pattern are damaged during transmission, the original data can be recovered due to the
redundancy of the transmission.
Dynamic IP Address
In a TCP/IP network, the client station is automatically assigned an IP address by a DHCP
server. The network devices, such as servers and printers, are usually assigned with static
(fixed) IP addresses.
