by bartleby guidelines i am allowed to do only one question, pls ask other questions separately.9). option (a) is correct. data Over Cable Service Interface Specification (DOCSIS) is a global media communications standard that allows the expansion of high-transmission capacity information move to a current satellite TV (CATV) framework. other options:- i). The Transmission Control Protocol (TCP) is a vehicle convention that is utilized on top of IP to guarantee dependable transmission of bundles. TCP incorporates systems to take care of large numbers of the issues that emerge from bundle based informing, like lost parcels, mixed up parcels, copy parcels, and adulterated parcels. ii). Ethernet links are utilized to give a web association, interface gadgets to a neighborhood organization. The most widely recognized use for an Ethernet link is associating a WiFi switch or modem to the web section port or phone line. iii). CSMA/CD is an adjustment of unadulterated transporter sense numerous entrance (CSMA). CSMA/CD is utilized to further develop CSMA execution by ending transmission when an impact is recognized, hence shortening the time needed before a retry can be endeavored.
