Characteristics of Computer Network Media

Characteristics of computer network media With the advent of Xerox 's Ethernet LAN (LAN) introduced in the early 1970' s, the telecommunications world welcomed this newly discovered gift. Since communication is an important aspect for all business today, familiarity with this amazing technology significantly improves company productivity and efficiency. In this article, we will compare and contrast these various media, reflecting the various characteristics of the media on which the LAN is based.

The topics of introduction of data transmission, information theory and computer network include transmission medium characteristics, multiplexing, error detection and correction, data security, communication protocol, packet switching, analysis of various network architectures, and selected commercial network environment The review is included. Computational theory and algorithm analysis and design research topics include context free grammar and syntactic analysis, finite automaton and regular languages, pushdown automata and contextless grammar, deterministic and non-deterministic Turing machines, determinability and computable Sex is included. In the field of algorithms, this course introduces the analysis and complexity of algorithms, search / sorting algorithms, mathematical algorithms, and graph theory algorithms. Introduction of complexity theory

Media convergence - a phenomenon involving the interconnection of information and communication technologies, computer networks, and media content. It is a summary of "3 C" - computing, communication, and content - a direct result of digitizing media content and popularity of the Internet.

A computer network or data network is a digital communication network that enables nodes to share resources. In a computer network, a computing device exchanges data with each other using connections between nodes (data link). These data links are established by a wired medium (such as a wire or fiber optic cable) or a wireless medium (such as WiFi). Network computer devices that initiate, route, and terminate data are called network nodes. Nodes are identified by network addresses and may include hosts such as personal computers, telephones, servers, and network hardware. If one device can exchange information with another device, it can be said that two such devices are connected over the network, regardless of whether they are connected directly to each other. In most cases, application-specific communication protocols overlap with other more general communication protocols (ie they are transmitted as payloads).
