Data communication refers to the transmission of the digital data between two or more computers The physical connection between networked computing devices is established using either cable media or wireless media. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. IEEE 802 is subdivided into 22 parts that cover the physical and data-link aspects of networking. • Describe the role and functions of each of the OSI layers. Each one can have a significant impact on how you handle networking projects in 2016 and beyond. This set of Data communication and Networking System Multiple Choice Questions and Answers (MCQs) focuses on “Data Communication and Networking Protocols and Standards”. Upon successful completion of this chapter, you will be able to: 1. understand the history and development of networking technologies; 2. define the key terms associated with networking technologies; 3. understand the importance of broadband technologies; and 4. describe organizational networking. Clipping is a handy way to collect important slides you want to go back to later. Long-distance telecommunications networks commonly use single-mode for its relatively higher bandwidth capacity, while local networks typically use multimode due to its lower cost. If you continue browsing the site, you agree to the use of cookies on this website. 802.11n (also sometimes known as Wireless N) was designed to improve on 802.11g in the amount of bandwidth it supports, by using several wireless signals and antennas (called MIMO technology) instead of one. 802.11n . Data communication standards Abstract: Effective communication of data among computer centers and remote terminals is essential to maximum utilization of current data processing resources. practical of data communication and networking for polytechnics and colleges of technology in line with current national board for technical education curriculum (NBTE). Two primary types of fiber optic cable industry standards are defined—single-mode (100BaseBX standard) and multimode (100BaseSX standard). The rise of open standards not owned by any one company has been a great boon to customers of computer and networking products, as well as the manufacturers that sell to them. ISO makes technical endorsements regarding data communication interfaces. • Use sequence and state transition diagrams to interpret and describe protocols. IEEE 802 Wireless Standards: Fast Reference: The IEEE 802 Standard comprises a family of networking standards that cover the physical layer specifications of technologies from Ethernet to wireless. The standards also help consumers choose from the multitude of available software systems and hardware equipment that have been certified to have met the standard requirements. Asked by Wiki User. Networking and Internet Standards Organizations. This protocol stack was developed in 1978 by Bob Kahn and Vint Cerf. TCP is a layer four (transport layer) connection-oriented protocol, which ensures the establishment of a connection between the source and destination before transferring data… IEEE 802 wireless standards. By Stephen Bucaro. Physical layer−It is the first layer that physically connects the two systems that need to communicate. Another international standard organization is the International Telecommunications Union-Telecommunications Group or ITU-T also located in Geneva, Switzerland, which is the technical-standard setting organization of the United Nations International Telecommunications Union. 5 6 7. These will allow the connectivity of per… Connection: In networking, a connection refers to pieces of related information that are transfered through a network. A temporary network can be formed by a small number of users without the need of an access point; given that they do not need access to network resources.The two current technologies for wireless personal area networks are Infra Red (IR) and Bluetooth (IEEE 802.15).
