The devices can be separated by a small many meters or almost unlimited distances. Computer networking is at times considered a sub-discipline of telecommunications, and sometimes of computer science, information technology and computer engineering. Computer networks depends lot upon the abstract and practical relevance of these scientific and engineering disciplines.
