Answer: Media access control layer (MAC layer)
Explanation:
The media access control layer is also known as MAC layer. The main function of the media access control layer is that it is used in the transmission of the data into the frame and perform the error detection and the address recognition which basically govern the accessing to the local area network (LAN) transmission medium.
The media access control layer is basically responsible for transmission of the data packets from NIC (Network interface card) to the another channel.

Answer:
Basically, dealing with the "software crisis" is what we now call software engineering. We just see the field more clearly now.
What this crisis was all about is that in the early days of the modern technological era -- in the 1950s, say -- there was tremendous optimism about the effect that digital computers could have on society, on their ability to literally solve humanity's problems. We just needed to formalize important questions and let our hulking "digital brains" come up with the answers.
Artificial intelligence, for example, had some early successes in easy to formalize domains like chess and these sorts of successes led to lots of people who should have known better making extremely naive predictions about how soon perfect machine translation would transform human interaction and how soon rote and onerous work would be relegated to the dustbin of history by autonomous intelligent machines.
Answer: this is an example of a contestable market
Explanation: The theory of contestable markets is associated with the American economist William Baumol. In essence, a contestable market is one with zero entry and exit costs. This means there are no barriers to entry and no barriers to exit, such as sunk costs and contractual agreements. In this case due the competition Microsoft may charge less for their product so the barrier's trend is to go down.
