Computer network operations (CNO) is a broad term that has both military and civilian application. Conventional wisdom is that information is power, and more and more of the information necessary to make decisions is digitized and conveyed over an ever-expanding network of computers and other electronic devices.
The computer industry has used the term "central processing unit" at least since the early 1960s. [37] Traditionally, the term "CPU" refers to a processor, more specifically to its processing unit and control unit (CU), distinguishing these core elements of a computer from external components such as main memory and I/O circuitry.

A network interface controller (NIC) is computer hardware that connects the computer to the network media and has the ability to process low-level network information. For example, the NIC may have a connector for plugging in a cable, or an aerial for wireless transmission and reception, and the associated circuitry.
Computer network engineering is a technology discipline within engineering that deals with the design, implementation, and management of computer networks. These systems contain both physical components, such as routers , switches, cables, and some logical elements, such as protocols and network services .
If k denotes the number of jobs in the system (either being serviced or waiting if the queue has a buffer of waiting jobs), then an arrival increases k by 1 and a departure decreases k by 1. The system transitions between values of k by "births" and "deaths", which occur at the arrival rates λ i {\displaystyle \lambda _{i}} and the departure ...
The Office of Tailored Access Operations (TAO), now Computer Network Operations, and structured as S32, [1] is a cyber-warfare intelligence-gathering unit of the National Security Agency (NSA). [2] It has been active since at least 1998, possibly 1997, but was not named or structured as TAO until "the last days of 2000," according to General ...
Computational mathematics is the study of the interaction between mathematics and calculations done by a computer. [ 1 ] A large part of computational mathematics consists roughly of using mathematics for allowing and improving computer computation in areas of science and engineering where mathematics are useful.
A computer operator is a role in IT which oversees the running of computer systems, ensuring that the machines, and computers are running properly. [1] The job of a computer operator as defined by the United States Bureau of Labor Statistics is to "monitor and control ... and respond to ... enter commands ... set controls on computer and ...
