The exercise is about filling in the gaps and is related to the History of the ARPANET.

From the text:

In 1972, earlier designers built the ARPANET connecting major universities. They broke communication into smaller chunks, or packets and sent them on a first-come, first-serve basis. The limit to the number of bytes of data that can be moved is called line capacity, or bandwidth.

When a network is met its capacity the user experiences unwanted pauses. When the network is "slowing down", what is happening is users are waiting for their packet to leave the queue.

To make the queues smaller, developers created mixed packets to move simultaneously.

Explanation:

Answer:

Network topology is the arrangement of the elements of a communication network. Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, industrial field buses and computer networks.

There are five types of topology in computer networks:

Mesh Topology.

Mesh topology is a type of networking where all nodes cooperate to distribute data among each other. This topology was originally developed 30+ years ago for military applications, but today, they are typically used for things like home automation, smart HVAC control, and smart buildings.

Star Topology.

A star topology is a topology for a Local Area Network (LAN) in which all nodes are individually connected to a central connection point, like a hub or a switch. A star takes more cable than e.g. a bus, but the benefit is that if a cable fails, only one node will be brought down.

Bus Topology.

A bus topology is a topology for a Local Area Network (LAN) in which all the nodes are connected to a single cable. The cable to which the nodes connect is called a "backbone". If the backbone is broken, the entire segment fails.

Ring Topology.

A ring topology is a network configuration in which device connections create a circular data path. Each networked device is connected to two others, like points on a circle. Together, devices in a ring topology are referred to as a ring network.

Hybrid Topology.

A hybrid topology uses a combination of two or more topologies. Hybrid networks provide a lot of flexibility, and as a result, they have become the most widely used type of topology. Common examples are star ring networks and star bus networks. Tree topology is one specific example of a star bus network.

Answer: In network layout, in terms of drafting RFP's, how computers are interconnected with each other physically, is a physical topology. In terms of how everything is connected to each other with the cables, on paper, that is a logical topology.

Explanation: Physical Topology is related to how the network actually appears as if you were in the room, looking at it. While logical topology, is usually a schematic on paper, showing how all of the devices are connected, which ports are they connected to, what are the Ip's, Mac addys, and such.

The code is a literal translation of the definition using a recursive function.

The recursive function is not per se a very efficient one.

The last valid host on the subnet 172.29.72.0/23 is 172.29.73.254.

To determine the last valid host on the subnet 172.29.72.0/23, we need to understand the concept of subnetting and how it affects the range of available host addresses.

In IPv4, subnetting allows for the division of a network into smaller subnetworks, each with its own range of usable host addresses.

The subnet 172.29.72.0/23 has a subnet mask of 255.255.254.0. The subnet mask determines the size of the network and the number of host addresses it can accommodate.

In this case, the /23 notation indicates that the first 23 bits are used to represent the network address, while the remaining 9 bits are available for host addresses.

To find the last valid host on this subnet, we need to determine the maximum number of hosts it can support. With 9 bits available for host addresses, we have 2^9 (512) possible combinations.

However, two of these combinations are reserved, one for the network address (172.29.72.0) and one for the broadcast address (172.29.73.255). Therefore, the actual number of usable host addresses is 512 - 2 = 510.

To find the last valid host address, we subtract 1 from the broadcast address.

In this case, the broadcast address is 172.29.73.255, so the last valid host address would be 172.29.73.254.

This is because the last address is reserved for the broadcast address and cannot be assigned to a specific host.

This cell is in column D and row 5, so it is cell D5. The column always comes first in a cell reference

Answer:

A. Encode the (negative) decimal fraction -9/2 to binary using the 8-bit floating-point notation.

First, let's convert -9/2 to a decimal number: -9/2 = -4.5

Now, let's encode -4.5 using the 8-bit floating-point notation. We'll use the following format for 8-bit floating-point representation:

1 bit for the sign (S), 3 bits for the exponent (E), and 4 bits for the mantissa (M): SEEE MMMM

Sign bit: Since the number is negative, the sign bit is 1: 1

Mantissa and exponent: Convert -4.5 into binary and normalize it:

-4.5 in binary is -100.1. Normalize it to get the mantissa and exponent: -1.001 * 2^2

Mantissa (M): 001 (ignoring the leading 1 and taking the next 4 bits)

Exponent (E): To store the exponent (2) in 3 bits with a bias of 3, add the bias to the exponent: 2 + 3 = 5. Now, convert 5 to binary: 101

Now, put the sign, exponent, and mantissa together: 1101 0010

So, the 8-bit floating-point representation of -9/2 (-4.5) is 1101 0010.

B. Determine the smallest (lowest) negative value which can be incorporated/represented using the 8-bit floating-point notation.

To get the smallest negative value, we'll set the sign bit to 1 (negative), use the smallest possible exponent (excluding subnormal numbers), and the smallest mantissa:

Sign bit: 1

Exponent: Smallest exponent is 001 (biased by 3, so the actual exponent is -2)

Mantissa: Smallest mantissa is 0000

The 8-bit representation is 1001 0000. Converting this to decimal:

-1 * 2^{-2} * 1.0000 which is -0.25.

The smallest (lowest) negative value that can be represented using the 8-bit floating-point notation is -0.25.

C. Determine the largest (highest) positive value which can be incorporated/represented using the 8-bit floating-point notation.

To get the largest positive value, we'll set the sign bit to 0 (positive), use the largest possible exponent (excluding infinity), and the largest mantissa:

Sign bit: 0

Exponent: Largest exponent is 110 (biased by 3, so the actual exponent is 3)

Mantissa: Largest mantissa is 1111

The 8-bit representation is 0110 1111. Converting this to decimal:

1 * 2^3 * 1.1111 which is approximately 1 * 8 * 1.9375 = 15.5.

The largest (highest) positive value that can be represented using the 8-bit floating-point notation is 15.5.

SELECT statement are used to retrieve data from a database table

The SELECT statement that creates the lesson schedule is:

SELECT LessonDateTime, HorseID, FirstName, LastName FROM LessonSchedule JOIN Student ON LessonSchedule.StudentID = Student.ID ORDER BY LessonDateTime ASC, HorseID

To write the select statement, we start by writing the following query that retrieves Lesson date/time, horse ID, first name, and last name from the lesson schedule table.

So, we have:

SELECT LessonDateTime, HorseID, FirstName, LastName FROM LessonSchedule

Next, the query would confirm the presence of a student ID in the lesson schedule table and the student table using the JOIN statement

JOIN Student ON LessonSchedule.StudentID = Student.ID

From the question, we understand that:

The result should be sorted in ascending order by lesson date/time.

This is represented as:

ORDER BY LessonDateTime ASC, HorseID

Hence, the complete query is:

SELECT LessonDateTime, HorseID, FirstName, LastName FROM LessonSchedule JOIN Student ON LessonSchedule.StudentID = Student.ID ORDER BY LessonDateTime ASC, HorseID
