Option 1 is correct. A 110 block is a type of insulation displacement connector used to terminate copper cabling at the back of a wall port or patch panel.

A structured cabling system may employ a 110 block, a form of punch-down block, to end on-premises cable runs. A type of insulation displacement contact (IDC) connection that terminates twisted pair cables and employs a punch-down tool similar to the one used for the earlier 66 block is referred to as 110.

Simple screw terminals were used in early residential telephone systems to connect cables to sockets in a tree topology. The 110 blocks and connectors have gradually taken the place of these screw-terminal blocks. Phone service typically enters modern homes by a single 110 block and is then disseminated in a star topology by on-premises wiring to outlet boxes all throughout the house. Cables are connected to ports at the outlet box that have insulation-displacement contacts (IDCs), and those ports are designed to fit into specific faceplates.

This type of home run or star topology wiring was already in use on 66 blocks in telecom closets and switchrooms in commercial settings. Particularly for use in data communications, the 110 block has been gradually taking the place of the 66 block.

An Ethernet frame is a data link layer protocol data unit used in computer networking that makes use of the Ethernet physical layer transport methods. In other terms, an Ethernet frame is the payload that a data unit on an Ethernet network transports.

A preamble and start frame delimiter (SFD), both of which are a component of the Ethernet packet at the physical layer, come before an Ethernet frame.

An Ethernet header, which has the source and destination MAC addresses as its first two fields, comes before every Ethernet transmission. Any headers for other protocols (like Internet Protocol) that are carried in the frame are included in the payload data in the center region of the frame.

Option c is correct. 802.19 is the open standard for tagging layer 2 frames. The IEEE 802 LAN/MAN Standards Committee's Technical Advisory Group (TAG) on Wireless Coexistence is known as 802.19.

Coexistence across unlicensed wireless networks is a topic covered by the TAG. Since several IEEE 802 wireless standards use unlicensed spectrum, coexistence is a problem that needs to be addressed.

The same unlicensed frequency band may be used by these unlicensed wireless devices in the same area. These two wireless networks may become hampered as a result.

If two unlicensed wireless networks can function side by side without seriously interfering with one another, that situation is referred to as coexistence. The coexistence of IEEE 802.11 and Bluetooth, both of which operate in the 2.4 GHz ISM frequency region, was one of the earliest instances of wireless coexistence.

The strands contain a coating of glass or plastic around the fibers. Depending on the transmission method, different patterns of light reflection are returned to the core. The fiber can curve around bends thanks to this reflection without losing the integrity of the light-based communication.

The cladding and core are shielded by a plastic buffer outside the cladding. The buffer absorbs any light that would escape because it is opaque.

Explanation:

Option b is correct. A member of a subtype is necessarily have to be a member of the supertype.

The properties and operations of a parent type are automatically passed down to its subtypes. Also, the inheritance relationship remains alive. Any modifications made to these attributes or methods in the parent are immediately inherited by subtypes; any changes made to a supertype's attributes or methods also affect subtype.

You can model an entity, like a customer, and specify other specialized subtypes of customers under the original type using object types in a type hierarchy. Once operations have been performed on a hierarchy, each type can implement and carry out the operation in a unique fashion.

Directly or indirectly, through intermediate levels of other subtypes, a subtype can be produced from a supertype.
