Different protocols are needed for different systems to "talk" to each other. Protocols are used to communicate, authenticate and used for error detection and recovery.
TCP/IP is the most common protocol, and is actually two distinct protocols, married together (TCP (Transmission Control Protocol) and IP (internet Protocol). Each protocol does a different "job". Others, such as FTP (File transfer protocol) are used for specific duties to be performed.
The protocol allows computers to talk to each other by setting the "ground rules". It allows for data to flow back and forth between the computers.
Imagine two people talking on the phone....one talks the other listens, then they reverse, and the talker becomes the listener. That is a Protocol! What happens when they both talk? Neither hears what the other says? What happens if the both listen, but not talk...no "data' is exchanged.
Standards are totally different, although related.....they are ground rules set by a commission so that hardware is compatible amongst similar computers, and assures interoperability. This is done (usually) to ensure backwards compatibility and compatibility from vendor to vendor. Again, imagine if each company made its own "protocol standard" and didn't allow it to talk with another's "protocol standard". That company would become very rich by being the sole provider, or out of business because nobody would bye it because of its uniqueness.
Wrapping it up...standards and protocols are what allow different computers, from different companies, running different software to communicate with each other. It's what made networking possible.
What else can I help you with?
How protocols work?
Protocols are set of standards that help programmers/designers/administrators to have common set of standards for Computing & Network Devices.
Is ipv6 compatible with ipv4?
IPv4 and IPv6 are two different protocols . The two protocols are not compatible with each other. But they can exist in a same network together.No, those are two different protocols. However, they can co-exist in the same network (this is known as "dual stack").No, those are two different protocols.

What are the different wireless local area network protocols?
wide area network
What network application establishes standards for the electronic exchange of data?
To be in a network and communicate we need to follow a set of rules and procedures . These set of rules and procedures are called protocols. So to exchange information these protocols should be followed.
What are the Set of formal rules used in describing how to transmit data across a network?
Those are the Standards - an agreed upon set of protocols (rules) to describe network communication.
What do you use for two networks that work on two different network protocols?
Gateway
What function do protocols perform in network communication?
protocols used for network device.

What are routed protocols?
Routed protocols are the best paths in a network along which to send network traffic.
Why is it necessary for routing protocols to include the subnet mask in their advertisements?
It is not necessary absolutely it is useful in that you can then advertise a subset of your network. For instance if you had the 10.x.x.x network you would not be able to break it into 10.1.x.x or 10.2.x.x networks
Why do you need standards for network management?
Standards are required in network management so that the devices manufactured by different vendors can inter operate with each other.
What are A group of interrelated protocols that are necessary to perform a communication function?
Protocol Suite in regards to the network fundamentals in Cisco questions.
