\Latest Update with Complete questions and
accurate answers
Along with an IP address, a primary gateway
subnet mask,
and a name server, the other
thing needed for a computer
to operate on a network is a
when a range of IP dynamic
addresses is set aside for
client devices, and one of
these IPs is
issued to these devices
when they request one,
this is known as
_______________ allocatio
n
The final step in the DHCP DHCPACK
discovery process is
known as
NAT stands for network address translation
when NAT hides the source IP masquerading
IP of an originating device
this is known as
,A service that might appear to reverse proxy
be a single server to external
clients, but actually
represents many servers living
behind it , is
known as
VPN stands for virtual private network
This is the layer 4 protocols. It ensures accurate delivery
Transport layer of data; solves transmission problems; provides error-
free reassembly and control traffic to be directed to
specific network applications.
This layer is on top of the 5 layer model and is for
Application layer applications that need to initiate communication with
other applications on a remote host. These services
work with the transport layer to send and receive
data.
multiplex, demultiplex The transport layer has the ability to ___________ and ___________
In the in the transport layer this term means that nodes
multiplex
on the network have the ability to direct traffic toward
many different receiving services.
In the transport layer this term means to take traffic that's
demultiplex
all aimed at the same node and delivering it to the
proper receiving service.
This is a 16-bit number used to direct traffic to specific
Port
services running on a networked computer.
Server or Service This is a program running on a computer waiting to be asked for
data.
Client A program that is requesting data.
Colon Ports are normally denoted with a after the IP address
This is an older method used for transferring files from
FTP
one computer to another, but you still see it in use
today
An IP datagram has a payload section and this is made up of
TCP
what's known as a _______ segment.
TCP segment This is made up of a TCP header and a data section
This section of the TCP segment is a payload area for
Data section
where the application layer places its data.
, This is a field in the TCP segment and has information
Destination port
about the port of the service the traffic is intended
for.
This is a field in the TCP segment and is a high numbered
Source port
port chosen from a special section of ports known as
ephemeral ports.
This is a 32-bit number that's used to keep track of
Sequence number
where in a sequence of TCP segments this one is
expected to be.
This is a field in the TCP segment and it has the number of the
Acknowledgement Number next expected
segment. Basically, a sequence number of one and an
acknowledgement number of two could be read as
this is segment one, expect segment two next.
This is a field in the TCP segment is a four bit number
data offset field that communicates how long the TCP header for this
segment is. This is so that the receiving network device
understands where the actual data payload begins.
This TCP segment field is a 16-bit number and specifies
TCP windows
the range of sequence numbers that might be sent
before an acknowledgement is required.
