A front-end processor (FEP) is a computer used in a network to manage connected computers and intercept data transmissions. It reduces the workload on the main host computer and is necessary for large networks. FEPs come with powerful hardware and allow for ethical interception of data.
A front-end processor (FEP) is a type of computer used in a network to help the main host computer manage other connected computers. The primary reason for using a front-end processor is to avoid the main computer having to do all the processing, which is resource intensive. Depending on how many nodes the FEP can connect to, the FEP can have relatively common hardware or very powerful hardware. To help administrators with security, these computers can often intercept data transmissions.
The purpose of a front-end processor is quite simple. In a network, there are many data transmissions going from the host to the nodes, back to the host and to other places. The host computer normally handles these broadcasts. When an FEP is used, it takes over the process of managing these transmissions and reports directly to the host.
While a host computer can perform these tasks without a front-end processor, there are many benefits to using an FEP. In networks where there are hundreds or thousands of nodes, this can be a difficult task for any single computer. The need for the computer to use resources to manage nodes means that the host computer must be very powerful if it is not to perform poorly on other tasks. For example, if the host user wants to run a program without using an FEP or having a robust system, the computer may take a long time to load and run the program.
A front-end processor usually comes with powerful hardware, but this depends on the size of the network. If your network is relatively small, such as fewer than 100 computers and devices, the FEP usually does not need to be very powerful and may have similar hardware to other computers. When the network is large, the FEP will typically need much more powerful hardware to ensure it can handle the management task without involving the host computer or crashing from stress.
Another reason to use a front-end processor is that it allows the host user to intercept data transmissions. This type of interception is ethical and fair, because the host user typically only looks for data that could compromise network security, trade secrets, or other information that network users shouldn’t transfer. All data passes through the FEP, so it is uniquely suited for this task.
