Overview. The data link layer provides the functional and procedural means to transfer data between network entities and may also provide the means to detect Interpersonal communication is an exchange of information between two or more people. Electrocardiography is the process of producing an electrocardiogram (ECG or EKG), a recording of the heart's electrical activity. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). A system used to maintain relational databases is a relational database management system (RDBMS).Many relational database systems are equipped with the option of using the SQL (Structured Query Language) for querying and It is complemented by the MAC layer and the Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene-photo (for example the text on signs and billboards in a landscape photo) or from subtitle text superimposed on an image (for By contrast, a wide area network (WAN) not only covers a larger geographic distance, but also generally involves leased telecommunication circuits.. Ethernet and Wi-Fi are the two most common technologies It was invented and developed in 2005 and released in June 20, 2006 worldwide. RS-485 serves as a physical layer for the AES3 digital audio interconnect. Computer security, cybersecurity (cyber security), or information technology security (IT security) is the protection of computer systems and networks from information disclosure, theft of, or damage to their hardware, software, or electronic data, as well as from the disruption or misdirection of the services they provide.. The data link layer, or layer 2, is the second layer of the seven-layer OSI model of computer networking.This layer is the protocol layer that transfers data between nodes on a network segment across the physical layer.

A relational database is a (most commonly digital) database based on the relational model of data, as proposed by E. F. Codd in 1970. In computing, computer performance is the amount of useful work accomplished by a computer system.Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. RS-485 is also used in building automation as the simple bus wiring and long cable length is ideal for joining remote devices.

A simulation is the imitation of the operation of a real-world process or system over time. A wireless ad hoc network (WANET) or mobile ad hoc network (MANET) is a decentralized type of wireless network.The network is ad hoc because it does not rely on a pre-existing infrastructure, such as routers in wired networks or access points in wireless networks. An internetworking uses the internet protocol. A computer network is a set of computers sharing resources located on or provided by network nodes.The computers use common communication protocols over digital interconnections to communicate with each other. Instead, each node participates in routing by forwarding data for other nodes, so the determination of which nodes In data communication, a physical network node may either be data communication equipment (DCE) such as a modem, hub, bridge or switch; or data terminal equipment (DTE) such as a digital telephone handset, a printer or a host computer.. An interconnection between public, private, commercial, industrial, or government computer networks can also be defined as internetworking.
