Webster defines it as &quot;Output or production, as of a computer program, over a period of time.&quot; &nbsp;I guess I'd define it as the total output achieved as a result of multiple input and processing devices. &nbsp;How about a cold one first? &nbsp;:-) &nbsp;I would look at data rate and transmission rate as they would pertain to a single pipe. &nbsp;Say a 10 meg input. &nbsp;Take a switch for example, if you have a single 10 meg input, the most you'll get out is 10 meg, even if the output is rated at 100 meg. &nbsp;Now aggregate 5 - 10 meg inputs, assuming that your output is capable of 100 meg, you get a theoretical output of 50 meg. &nbsp;The Through-put is more the total output. &nbsp;Does that make sense? &nbsp;

Hello can you give me the definition of the word troughput? Is there a difference between troughput and data rate or transmission rate? Which word do we use when we want to speak about the rate of useful data bytes only and ignore the encapsulation bytes of the protocol? <br />
<br />
Please be clear because I'm confused.<br />
<br />
Thank you!

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

Network analysis is the process of identifying and remediating the processes and systems within a network, including performance, connectivity and security. The process is performed through the use of tools developed for monitoring and analyzing network activity. Network problems that involve finding an optimal way of doing something are studied under the name combinatorial optimization. Examples include network flow, shortest path problem, transport problem, transshipment problem, location problem, matching problem, assignment problem, packing problem, routing problem, Critical Path Analysis and PERT (Program Evaluation & Review Technique).

Network Analysis

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
