Which of the following is also known as "Thicknet" or "yellow wire" and has additional copper mesh shielding?

The term "Thicknet" refers specifically to 10Base5 cable, which was one of the early architectures for Ethernet networking. This cable is characterized by its thicker gauge and its additional copper mesh shielding, which helps to reduce electromagnetic interference and allows for longer distances between devices on the network. The "yellow wire" nickname comes from the standard color of the outer insulation used on this type of cable, making it easily recognizable.

10Base5 supports a maximum length of 500 meters and can connect multiple devices through the use of transceivers along the main cable. The additional shielding is a significant feature that enhances its durability and transmission quality compared to other types of coaxial cables that do not have such robust shielding.

In contrast, the other options refer to different types of Ethernet cables: 10Base2 is a thinner coaxial cable commonly called "Thinnet", 10BaseT is a twisted-pair cable standard that supports connections over shorter distances, and 10BaseF refers to fiber-optic Ethernet cabling. Each of these cable types has different characteristics and uses, which are not aligned with the description of having additional copper mesh shielding akin to that found in 10Base5.
