I have a research about the networks, but I am confused about sub-topicts, I need a topic more specific, help.

Question

the problem that I want to make a research about some thing in networks, but I need your suggesitions.

Answer 1

There are dozens of subtopics and sub-subtopics in networking. Someone mentioned security, a great and hot topic in networking. But you might want to get even more specific, for example, the security subtopic of cryptography. You could select from dozens of other subtopics such as protocol design, fiber optics, wireless networking, storage area networks, Voice over IP, Internet multicasting, routing algorithms, public key cryptography, TCP/IP, error and flow control mechanisms, etc.

Answer 2

you could do research on how a request for a web server is processed. FOr example

you put

http:://yahoo.com:80

for the browser address.

First your computer looks up the address of yahoo.com by doing a nslookup. (try nslookup yahoo.com from your command prompt) Then your computer sends the request to the IP address. Along the way there is a chain of routers that hand off the message one at a time. Kind of like a line of people passing a note from one person to the next. Then it gets to the yahoo.com firewall on port 80 where it lets your request go to the webserver (www) then it processes the request and gives you special information depeding on your IP address (try ip2location.com)

Now if you were a person trying to do bad things to the yahoo site, they could block you at the firewall by not allowing your IP address to make any requests.


Another topic might be the physical location of the internet. Go to ip2location.com and see your address and your location. Then put in some different IP addresses from doing a nslookup at your command prompt on yahoo, and google...etc. Make a map and show the locations of yahoo, and google, etc...from the ip2location.com lookup.
