Let’s review some of the terminology used in this textbook. Recall that the name of a transport-layer packet is segment and that the name of a link-layer packet is frame. What is the name of a network-layer packet? Recall that both routers and link-layer switches are called packet switches. What is the fundamental difference between a router and link-layer switch?

Expert Solution & Answer

Program Plan Intro

Link Layer:

Link layer is the aggregation of procedures and protocols used in a link to share the data between the nodes. It includes mainly three functions namely, detection of transmission errors, regulation of data flow and provides well-structured interface.

Explanation of Solution

Description of network layer packet:

Network layer is provides the path in which the data packets are transferred from the source to the destination.
It also helps in converting the logical or Internet Protocol (IP) address to physical or Media Access Control (MAC) address.
The packet related to network layer can be termed as datagram.

Differences between router and link layer switch:

Router	Link layer switch
The router process in the internet protocol is done by network layer, link layer and physical layer. In latest routers, transport layer is also included.	The link layer switch process is done using data link layer and physical layer.
A router transmits the data packet using IP layer address.	A link layer transmits the data frames using MAC layer address.
In router, the data in transmitted in the form of packets or data packets.	In link layer switch, the data is transmitted in the form of frames or data frames.
It is used in Local Area Network (LAN), Wide Area Network (WAN) and Metropolitan Area Network (MAN).	It is used in LANs only.
In this, the data is transmitted in full duplex mode.	In this, the data is transmitted in both full duplex and half duplex modes.

We want to get an idea of how many tickets we have and what our issues are. Print the ticket ID number, ticket description, ticket priority, ticket status, and, if the information is available, employee first name assigned to it for our records. Include all tickets regardless of whether they have been assigned to an employee or not. Sort it alphabetically by ticket status, and then numerically by ticket ID, with the lower ticket IDs on top.

Figure 1 shows an ASM chart representing the operation of a controller. Stateassignments for each state are indicated in square brackets for [Q1, Q0].Using the ASM design technique:(a) Produce a State Transition Table from the ASM Chart in Figure 1.(b) Extract minimised Boolean expressions from your state transition tablefor Q1, Q0, DISPATCH and REJECT. Show all your working.(c) Implement your design using AND/OR/NOT logic gates and risingedgetriggered D-type Flip Flops. Your answer should include a circuitschematic.

A controller is required for a home security alarm, providing the followingfunctionality. The alarm does nothing while it is disarmed (‘switched off’). It canbe armed (‘switched on’) by entering a PIN on the keypad. Whenever thealarm is armed, it can be disarmed by entering the PIN on the keypad.If motion is detected while the alarm is armed, the siren should sound AND asingle SMS message sent to the police to notify them. Further motion shouldnot result in more messages being sent. If the siren is sounding, it can only bedisarmed by entering the PIN on the keypad. Once the alarm is disarmed, asingle SMS should be sent to the police to notify them.Two (active-high) input signals are provided to the controller:MOTION: Asserted while motion is detected inside the home.PIN: Asserted for a single clock cycle whenever the PIN has beencorrectly entered on the keypad.The controller must provide two (active-high) outputs:SIREN: The siren sounds while this output is asserted.POLICE: One SMS…
