  • What kind of Router offers both a wired and wireless connection?
Without the data link layer, network protocols such as IP, would have to make provisions for connecting to every type of media that could exist along a delivery path. Moreover, IP would hav to adapt every time a new network technoplogy or medium developed. This process would hamper protocol and network media innovtioon and development. This is a key reason for using a layered apprtoachj to networking

to identify which network layer protocol is being used. Defining the media access processes that are performed by the hardware and providing data link layer addressing are functions of the MAC sublayer. The data link layer accepts Layer 3 packets and packages them into data units that are called frames.

Encoding or line encoding is a method of converting a stream of data bits into a predefined "code". Codes are groupings of bits used to provide a predictable pattern that can be recognized by both the sender and the receiver. In the case of networking, encoding is a pattern of voltage or current used to represent bits; the 0's and 1s.

  • What are the 2 sublayers of the Data-Link Layer?
[1] Security [2] Coverage Area[3] InterferenceThe three areas of concern for wireless networks focus on the size of the coverage area, any nearby interference, and providing network security. Extensive cabling is not a concern for wireless networks, as a wireless network will require minimal cabling for providing wireless access to hosts. Mobility options are not a component of the areas of concern for wireless networks.
