what's the purpose of TCP/IP protocol?

I am having a tough time trying to answer these questions and it seems like I can't find an answer to them. This is not an assignment questions , it's just for the revision because I'll be writing an examination in a couple of days.Please help me.

1.What is the purpose of TCP/IP protocol in the internet implementation.
2.Discuss two major functions od a client/server network operating system.

Easy.

1.  To standardize the methodology of information exchange between networked devices.

2.  To be able to connect to services host on remote devices, and to be able to host services accessible by other remote devices.

I hope they give you an A

1)
TCP/IP is a combination of 2 protocols to ensure a packet which is sent from the sender to the receiver will arrive in a correct way.
TCP provides the control that the content of the package is not changed during transport
IP provides the address of the source and the destination. The IP will be used for determining the routes.

2)
Can you clarify "client/server network operating system"?
Do you mean client/server applications?
* Centralising data and de-centralising other resources. (mem, cpu, ...)

Actually, tcp/ip is more than 2 protocols, its a suite of protocols (http,ftp,smtp,pop3,etc)

I like the captain's answer for #1, which I will add to:

TCP is a protocol that provides a reliable connection between two network devices.

But please give credit to captain.

SunBowCommented:
IP = Internet Protocol - for communicating on internet.

Note: it is not - Internet Protocol Protocol (<>IPP)

Among its uses is by TCP, which runs 'over' it. hence

TCP/IP = TCP over IP

see also: ISO/OSI re: layered topology

network operating system (NOS) main function is serving. Such as for files, for communications, etc.

For client / server, try posting questions in the topic areas (TAs) for database(s).

> "1.What is the purpose of TCP/IP protocol in the internet implementation."

Well, what is it you have learned so far about its purpose in all other implementations?          ;)

> "two major functions od a client/server "

(a) to have client; (b) to have server

Note that much can lie in context, in usage, to determine any... 'best' answer, which usually lies in the mind of a grader. I not one prepared to read such mind. Or adapt, either.

Oops - the new interface sucks so much I didn't even notice the pt split already had taken place (what was I thinking not using oldlook.experts-exchange.com)?  

That's just great.
