Exercise 2: Minimization of scheduling conflicts The transpose of a matrix is formed by interchanging the matrix's rows and columns. Thus the transpose of matrix of 4 2 6 10 A = 6 8 is A' = 10 12 The organizers of an in-house Cloud Computing conference for small consulting company are trying to minimize scheduling conflicts by scheduling the most popular presentations at different times. First the planners survey the ten participants to determine which of the five presentations they want to attend. Then they construct a matrix A in which a 1 in entry ij means that participant i wants to attend presentation j. The following table and matrix (A) give information about the participation. Participant 4 Presentation 1 2 1 1 0 10101 00 1 1 1 10000 3 4 1 0 20 00 11 1 0011 1000 0 V 3 4 It means matrix A= 01101 00000 11000 6 0 1 1 0 1 00000 00000 11000 00101 01010 1 0 1 0 1 00010 7 00101 8 9 01010 10 10 1 0001 0 10 Next the planners calculate the transpose of A(A') and the matrix product of A' x A. In the resulting matrix, entry ij is the number of participants wishing to attend both presentation i and presentation j. We then have A' XA= 4 1202 1 3 11 1 215 15 01131 21515 notice that B = A' x A is symmetric (Bij = Bj, for all i, j), so the entries below the main diagonal (entries i where i < j) need not be calculated. If we supply zeros for the unnecessary entries, the resulting matrix is termed upper triangular matrix. The entries on the main diagonal (Bii) represent the total participants wanting to attend presentation i. (a) Write a C function TotalPart that creates the matrix A of participants preferences, from data received from data read from a file as sequence of couples of integers, where the first couple is such that the first number represent the number of presentation and the second number represents the number of participants and the rest of couples are such that for each couple the first number represents the participant and the second number represents one of the presentations he/she wants to attend; this means a participant can appear several times in the sequence if he/she wants to attend more than one presentation. For example, the file containing the sequence 3 4 1 2 3 4 1 431 24 will produce A = 01 0 0001 0 0 1 C then Cij = (b) Given a matrix T with n rows and p columns and a matrix S with p rows and q columns, if the product T x S is equal to p-1 Tik x Skj, where i=0,1.....n-1 and j = 0,1.....q-1. Given the matrix of preferences A write the function ComputeAtA that computes A¹ x A and saves it in another matrix C, and displays how many participants wish to attend each conference. k=0 (c) Write a C function AvoidBadSchedule that receives as argument the matrix A of preferences, finds the three largest numbers in the entries above the main diagonal of A' x A, and displays on the screen up to three pairs of presentations that the conference committee should avoid scheduling at the same time. You will display fewer than three pairs if one(or more) of the three largest number is 1. (d) Provide a driver program that prompts the user to enter the name (scheduling.txt) the file containing the attendance to presentations sequence as described in (a), and displays the pairs of presentations to be avoided. 6 5

False. In the data view of SPSS (Statistical Package for the Social Sciences), each row represents a separate observation (e.g., individual, respondent, case) in the dataset, while each column represents a variable.

Typically, a dataset in SPSS consists of multiple variables that capture different aspects of the observations. For example, if you have survey data on consumer preferences, each row would represent a different respondent, and each column would represent a different variable, such as age, gender, income, and product preference.

By organizing the data in this way, SPSS allows for easy analysis and manipulation of the dataset. Researchers can apply various statistical procedures, run tests, generate descriptive statistics, and explore relationships between variables.

It's essential to understand the structure of the data view in SPSS to correctly input, manage, and analyze data. Remember, each row represents a different observation, and each column represents a different variable.

This organization facilitates data analysis and ensures accurate interpretation of results.

Based on the given information, we can say that computer 2 has a faster instruction execution time compared to computer 1. The fact that instructions on computer 2 take 5 nsec to execute, while on computer 1 they take 10 nsec, suggests that computer 2 can process instructions in half the time it takes for computer 1.

However, it's important to note that the instruction execution time alone does not provide a complete picture of a computer's overall speed or performance. Other factors such as clock speed, processor architecture, cache size, memory access speed, and overall system design can also impact the overall performance of a computer.

To make a comprehensive assessment of the speed or performance of two computers, it is necessary to consider these additional factors and possibly conduct benchmark tests or performance evaluations on both systems.

To start a transaction, insert a new actor, and set a savepoint in a database, the following steps can be followed:
1. Begin a transaction.
2. Execute an SQL statement to insert a new actor with the specified values.
3. Set a savepoint within the transaction.

Starting a transaction is typically done using the "BEGIN TRANSACTION" or similar statement, depending on the specific database system being used. This ensures that all subsequent operations are part of the same transaction.
To insert a new actor with the given values, an SQL statement like "INSERT INTO actors (id, first_name, last_name, created_at) VALUES (999, 'nicole', 'streep', '2021-06-01 12:00:00')" can be executed. This adds a new record to the "actors" table.
Once the actor is inserted, a savepoint can be set within the transaction using the appropriate command provided by the database system. The savepoint allows for creating a point of reference within the transaction, which can be used for rollback purposes or to undo changes made after the savepoint.
In summary, to achieve the desired operations, begin a transaction, execute an SQL insert statement to add a new actor, and set a savepoint within the transaction.

If the TTL value was set to 64 at the start, the TTL (Time to Live) value once it arrives at its destination is 61. (Choice D)

TTL (Time To Live) is a counter that stops packets on a network from circulating indefinitely. The TTL value is reduced by one for each hop as a packet is transported from one computer to another (router). If the TTL value approaches zero before the packet gets at its destination, it is rejected, and the sender receives an error message. In this case, the packet sent from Computer 1 to Computer 2 has a TTL of 64. If the two computers are not immediately linked.

Assuming that no packets are lost or corrupted during transmission, the web server will acknowledge the receipt of the first three packets by sending an acknowledgement (ACK) packet to the PC.

The ACK packet will contain the next byte of information that the web server is expecting to receive from the PC.

To determine which byte of information the web server will acknowledge after it has received three packets of data from the PC, we need to consider the following:

The TCP window size of 6,000 bytes indicates the maximum amount of unacknowledged data that the PC is allowed to send to the web server.

The packet size of 1,500 bytes indicates the amount of data that is being sent in each packet.

Based on this information, we can calculate that the PC will send three packets of data containing a total of 4,500 bytes (3 x 1,500 bytes) to the web server. The web server will acknowledge the receipt of all three packets by sending an ACK packet that contains the next byte of information that it is expecting to receive from the PC, which will be the byte immediately following the last byte of the third packet.

Therefore, the byte of information that the web server will acknowledge after it has received three packets of data from the PC will be the byte immediately following the last byte of the third packet, which is byte number 4,501.

A computer technician has set up a NAS (Network Attached Storage) for a company using two 1 TB hard drives operating at 7200 RPM in a RAID 1 configuration. In this setup, the usable storage space is 1 TB.

RAID 1 provides redundancy by mirroring the data on both hard drives, ensuring that if one drive fails, the data remains available on the other drive. However, this redundancy means that the total usable storage space is equal to the capacity of one hard drive, which in this case is 1 TB.

Since the technician has installed two 1 TB hard drives, the total capacity of the NAS is 2 TB. However, in RAID 1 configuration, the data is mirrored, which means that only one of the hard drives is being used to store data. Therefore, the usable storage space in the NAS would be 1 TB.

Note that the actual usable storage space may be slightly less than 1 TB due to formatting and other overheads associated with the operating system and file system used on the NAS.
