I figured that we all like a bit of a continuous quiz and so I thought I'd put out a few questions for your entertainment. Let me know what you think and obviously give your answers.
First off, applications to protocols.
Below is a list of commonly used applications. These will mainly use either TCP or UDP as their connection protocol. Your job is to produce two lists detailing the correct grouping.
Applications:
HTTP
VoIP
DHCP
DNS
FTP
SNMP
Telnet
SMTP
TFTP
There are some trick applications above, let's see who catches on!
And so, the answers are:
You did well on that one DL, so here's another.
What is the name of the process completed by a host machine to determine the network portion of an IPv4 Address with a Subnet Mask?
Thanks, that's actually a pretty useful list!
I think NAT is a better name :¬)
What is the name of the process completed by a host machine to determine the network portion of an IPv4 Address with a Subnet Mask?
Is:
ANDing
The ANDing process takes the IPv4 address, converts it to binary, takes the subnet mask, converts that to binary and then completes logical ANDing.
So, IP 192.168.1.1 would be represented in binary as
11000000.10101000.00000001.00000001
Subnet mask 255.255.255.0 would be represented in binary as:
11111111.11111111.11111111.00000000
If we use the logical AND operator to compare these two values we get:
11000000.10101000.0000001.00000000
This shows that the first three groups (octets) represent the network portion of the address and the final octet represents the host portion of the address.
This process is then used by devices to determine whether to send network traffic locally using a Layer 2 device (switch) or to send it to a Layer 3 device (router) most commonly the default gateway.
Another question is on its way.

I realise the error of my ways Eccles, old age and associated factors ... it's UDP :¬)
