This set of Data communication and Networking System Multiple Choice Questions and Answers (MCQs) focuses on “Data Communication and Networking Protocols and Standards”. IEEE 802 wireless standards. IEEE stands for Institute of Electrical and Electronics Engineers. Before we begin discussing networking with any depth, we must define some common terms that you will see throughout this guide, and in other guides and documentation regarding networking.These terms will be expanded upon in the appropriate sections that follow: 1. Our members and volunteers are an integral part of the development and implementation of standards in the communications field. Looks like you’ve clipped this slide to already. Which standards do you think will have the biggest impact for you in the near future? Just like other fields in the industry, a set of standards have been put in place for data communication and networking. IEEE 802 is subdivided into 22 parts that cover the physical and data-link aspects of networking. The IEEE 802 standard is a collection of networking standards that cover the physical and data-link layer specifications for technologies such as Ethernet and wireless. It simply tells what each layer should do by defining its input and output data. It's responsible for the guaranteed transfer of information across a network. Just like other fields in the industry, a set of standards have been put in place for data communication and networking. IEEE is an organization composed of engineers, scientists, and students. 802.11n also offers a somewhat better range over … 1 The key element of a protocol is _______. 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. These will allow the connectivity of per… In order to facilitate the development of open standards, however, organizations are needed that will coordinate the creation and publishing of these documents. Physical Addressing and Switching. This organization is also unique compared to the other standardization organizations in that they do not require an official membership to be a participant. The best-known computer network is the Internet. Clipping is a handy way to collect important slides you want to go back to later. Network protocols and standards Get Started. 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). The IEEE 802 family of standards has twelve members, numbered 802.1 through 802.12, with a focus group of the LMSC devoted to each. Please note, there is an updated edition of this book available at https://opentextbook.site. Here is the List of IEEE standards in Computer Networks and their functions.
