[amp_mcq option1=”TRUE” option2=”nan” option3=”nan” option4=”nan” correct=”option1″]<\/p>\n
The correct answer is FALSE<\/strong>. A MAC address is a 12-digit hexadecimal number that is assigned to network interfaces for communications on the physical network segment. It is written in the form of six pairs of hexadecimal digits separated by colons, for example: 00:11:22:33:44:55.<\/p>\n The first three pairs of digits are assigned by the Institute of Electrical and Electronics Engineers (IEEE) to identify the manufacturer of the network interface. The last three pairs of digits are assigned by the manufacturer to identify the specific network interface.<\/p>\n MAC addresses are used in the Media Access Control (MAC) sublayer of the Data Link Layer of the Open Systems Interconnection (OSI) model. They are used to identify devices on a network and to control access to the network.<\/p>\n MAC addresses are not case sensitive.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”TRUE” option2=”nan” option3=”nan” option4=”nan” correct=”option1″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[730],"tags":[],"class_list":["post-58840","post","type-post","status-publish","format-standard","hentry","category-internet-of-things-iot","no-featured-image-padding"],"yoast_head":"\n
