Answer #1

ANSWERS -

1) Data link layer which is layer 2 of OSI model we can find frames, it is the protocol data unit.

2) The different frame transmission methods are -

  • Fixed size framing - frame size is fixed, frame length are delimiters
  • Variable size framing - Size of frame varies

3) Functions of -

  • SYN - Synchronous idle function is to provide signal from which synchronous correction to data terminal.
  • STX - Start of text control character defines the start of text block.
  • ETX - End of text character function is to inform the destination/receiving device that the end of stream has been reached in data link layer.

4) Ethernet is the technology to connect devices in LAN and WAN. The IEEE standard for Ethernet is IEEE 802.3.

Part 1 Directions: List the number of sales (Y) at the stated price point (x). Find a demand function D(x) which outputs Y when you input x. This function should be decreasing (negative derivative). Y= 1000 X= $20 For D(x) I got D(x) = 20100-5x. If you find a is a better Y and X please use it, this is just what I chose to use.

We can use the Cournot model to derive an equilibrium industry structure. For this purpose, we will define an equilibrium as that structure in which no firm has an incentive to leave or enter the industry. If a firm leaves the industry, it enters an alternative competitive market in which case it earns zero (economic) profit. If an additional firm enters the industry when there are already n firms in it, the new firm’s profit is determined by the Cournot...

Castaneda v. Partida is an important court case in which statistical methods were used as part of a legal argument. When reviewing this case, the Supreme Court used the phrase "two or three standard deviations" as a criterion for statistical significance. This Supreme Court review has served as the basis for many subsequent applications of statistical methods in legal settings. (The two or three standard deviations referred to by the Court are values of the z statistic and correspond to...
