The correct answer is: C. IEEE 802.11
IEEE 802.11 is a set of standards for wireless local area networks (WLANs). It defines the physical layer (PHY) and medium access control (MAC) layer specifications for implementing WLANs. The PHY layer specifies the modulation and coding schemes used to transmit data over the air, while the MAC layer specifies how devices access the shared wireless medium.
IEEE 802.11 is a very popular standard, and it is used in a wide variety of products, including laptops, smartphones, and tablets. It is also used in many enterprise networks.
IEEE 802.11 has been through several revisions over the years, and the latest version is IEEE 802.11ac. IEEE 802.11ac offers significant improvements in speed and range over previous versions of the standard.
Here is a brief description of each option:
- IEEE 802.3 is a set of standards for wired local area networks (LANs). It defines the physical layer (PHY) and medium access control (MAC) layer specifications for implementing LANs. The PHY layer specifies the electrical and signaling characteristics of the physical medium, while the MAC layer specifies how devices access the shared wired medium.
- IEEE 802.16 is a set of standards for wireless metropolitan area networks (WMANs). It defines the physical layer (PHY) and medium access control (MAC) layer specifications for implementing WMANs. The PHY layer specifies the modulation and coding schemes used to transmit data over the air, while the MAC layer specifies how devices access the shared wireless medium.
- IEEE 802.15 is a set of standards for wireless personal area networks (WPANs). It defines the physical layer (PHY) and medium access control (MAC) layer specifications for implementing WPANs. The PHY layer specifies the modulation and coding schemes used to transmit data over the air, while the MAC layer specifies how devices access the shared wireless medium.
