ELINT refers to intelligence gathered from electronic signals. These signals might come from radio pulses, electromagnetic pulses, radars, missiles, guidance systems, or aircraft. Unlike COMINT, ELINT is intelligence derived from noncommunication electronic signals, i.e., signals that donotcontain speech...

Switches:A switch is a device that connects network devices and manages node-to-node communication across a network, making sure that data packets reach their intended destination. Unlike routers, which send informationbetweennetworks, switches send information between nodeswithina network. Consequently, ...
In some digital communicationprotocols, ACK -- short foracknowledgement-- refers to a signal that a device sends to indicate thatdatahas been received successfully. The signal is sent by a receiving station (destination) to the sending station (source) after the receipt of a recognizable block o...
The purpose of a hub is to form a single network segment on which all devices can communicate directly with each other. Until the early 2000s,Ethernethubs were widely used for home networking due to their simplicity and low cost. Whilebroadband routershave replaced them in homes, hubs still ...
Since I do research on Internet-based CMC, this definition is oriented to that context; but I don't mean to imply here that all CMC is Internet-based. I believe that process and context are key themes in the study of computer-mediated communication. ...
CMC involves the use of computers in all areas of communication, that is, individuals use computers to communicate with each other across time zones... Learn more about this topic: Computer-Mediated Communication | CMC Definition & Examples ...
From the early 1900s until now, long distance communication has primarily been in the form of the telephone line. Now telephone lines are being used for more than the transmission of voice; they are also used for the transmission of computer data. There
computer networks are made up of two or more computers connected together through cables or wireless signals. these connections allow for the transmission of data between all computers on the network, allowing for efficient communication and sharing of resources. why is using a computer network ...
computernetwork is to exchangeinformationbetween two entities. The figure shows a particular example of communication between a workstation and a server through a public telephone network. Another possible example is the exchange of voice signals between two telephones through the same previous network....
