A negotiation sequence can be done via a technique known as Hand-shaking, for a reliable protocol. It might be called other things by others depending on vernacular, etc.
Usually the two devices decide on how they will exchange information on negotiation.
These are called protocols - a standard set of rules for common communications across networks.
A protocol is a set of rules describing some behavior. In order to communicate in a common manner, the sender and receiver have to agree on the "language" of communication. A protocol states what those rules are, and because they are a standard, everyone agrees and knows what to expect.
-Programmed services and protocols that move the messages across the network -Technologies that support network communications

Protocols are set of standards that help programmers/designers/administrators to have common set of standards for Computing & Network Devices.
That's a network.
That is called a network.
What is a Network, Alex? *to have a network, you will also need a common communication protocol.
a network.

BANDWIDTH available for communications between interconnected devices is the main thing that characterises a network.
Network protocols provide mechanisms that enables communications between sysytems, clients, servers, websites etc. without protocola systems would not be able to communicate, share data etc.
