which of the following protocols does not have collisions? (1 point) slotted aloha pure aloha csma (carrier sense multiple access) none of the above response is correct

Answers

Answer 1

The protocol that does not have collisions is slotted aloha.

Collisions occur in data transmission when two or more nodes transmit data on the same communication channel at the same time.

This results in the overlapping of the transmitted data, which makes it impossible for the receiving nodes to correctly interpret the data.

CSMA/CD and pure aloha are two methods used to minimize collisions in data transmission. CSMA involves a node sensing the medium (communication channel) for a carrier signal before transmitting data. If the channel is free, the node can transmit the data; if not, it waits for a random time and repeats the process.

Pure aloha, on the other hand, does not sense the channel before transmitting data. Instead, it just sends the data. If a collision occurs, the nodes involved wait for a random amount of time before retransmitting.The slotted aloha protocol is an improvement over pure aloha. Instead of allowing nodes to send data whenever they want, nodes wait for specific time slots to send data.

This helps to minimize collisions since nodes are less likely to transmit data at the same time.Therefore, among the given options, slotted aloha is the protocol that does not have collisions.

Which of the following is a key feature of extreme programming (XP)?
A - Emphasis on individual effort
B - Use of traditional software development techniques
C -Integration of the developmental phases
D -Continuous communication among key players

Answers

The key feature of extreme programming (XP) is "option D - continuous communication among key players".

1. Extreme Programming is an agile software development methodology that emphasizes collaboration, flexibility, and responsiveness to customer needs. Continuous communication is at the core of XP and plays a vital role in its success.

2. In XP, developers, customers, and other stakeholders are in constant communication throughout the development process. This includes regular and frequent interactions, such as daily stand-up meetings, in which key players discuss progress, challenges, and plans for the day.

3. Continuous communication promotes a high level of collaboration and feedback. It allows for rapid response to changing customer needs, as developers can quickly gather feedback, make adjustments, and iterate on the software.

4. Furthermore, communication in XP extends beyond just the development team. XP encourages close collaboration between developers, customers, testers, and other stakeholders. This helps bridge the gap between business and technical aspects, ensuring that the software being developed aligns with the customer's expectations and needs.

uppose the cache access time is 10ns, main memory access time is 200ns, the hard drive access time is 10ms, the tlb hit rate is 98%, the cache hit rate is 95% and the page fault rate is 0.001%. assuming non-overlapped access, what is the average access time for the processor to access an item

Answers

The average access time for the processor to access an item is 19.5.

What is average access time?

Average access time is defined as a standard statistic for evaluating the performance of computer memory systems. Access time is the amount of time it takes for an electronic system to respond to a request and provide the needed data.

Main memory access time = 200 ns

Cache access time = 10 ns

Hit ratio = 0.95

Average access time

= 0.95 x 10 + ( 1 - 0.95 ) x 200

= 9.5 + 0.05 x 200

= 9.5 + 10

= 19.5

Thus, the average access time for the processor to access an item is 19.5.

(90pts) write a scheme (using dr. racket) program to perform binary search.

Answers

To perform binary search in Scheme using Dr. Racket, you can define a recursive function that takes a sorted list and a target element as parameters. Here's an example implementation:

```scheme

(define (binary-search lst target)

 (define (search low high)

   (cond

     ((> low high) #f) ; Element not found

     (else

       (let* ((mid (quotient (+ low high) 2))

              (mid-elem (list-ref lst mid)))

         (cond

           ((= mid-elem target) mid) ; Element found

           ((< mid-elem target) (search (+ mid 1) high)) ; Search right half

           (else (search low (- mid 1))))))) ; Search left half

 (search 0 (- (length lst) 1)))

;; Example usage:

(define my-list '(2 4 6 8 10 12 14))

(display (binary-search my-list 8)) ; Returns 3 (index of 8 in the list)

```

The `binary-search` function takes a sorted list `lst` and a target element `target`. It defines an inner helper function `search` that performs the actual binary search by recursively narrowing down the search range until the element is found or the range is exhausted. The function returns the index of the target element if found or `#f` if not found.

The given code snippet defines a procedure named slice which takes three arguments: s (presumably a sequence), start (the starting index), and end (the ending index).

The code also defines a variable nat which is assigned the result of calling the naturals procedure with an argument of 0. The naturals procedure, however, is not provided in the given code snippet.Assuming the naturals procedure generates an infinite sequence of natural numbers starting from 0, the expression (slice nat 4 12) will return a subsequence of nat starting from the 4th index and ending at the 12th index. In this case, the result would be the list (4 5 6 7 8 9 10 11), which represents the natural numbers 4 through 11 (inclusive).Please note that without the implementation of the naturals procedure, it is not possible to accurately determine the result of the (slice nat 4 12) expression

Problem 3( 2 Marks) Given :u= 0,1,3,-6) and v = (-1,1,2,2), a- Compute the projection of u along v. b- Compute the projection of v along u.

Answers

Projections of the vector is given as;

a) The projection of u along v is: (-0.5, 0.5, 1, 1)

b) The projection of v along u is: (0, 0, 0, 0)

To compute the projection of one vector onto another, we use the formula:

proj_v(u) = ((u . v) / (v . v)) * v

where "u . v" denotes the dot product of u and v, and "v . v" represents the dot product of v with itself.

a) Projection of u along v:

u . v = (0 * -1) + (1 * 1) + (3 * 2) + (-6 * 2) = -2 + 2 + 6 - 12 = -6

v . v = (-1 * -1) + (1 * 1) + (2 * 2) + (2 * 2) = 1 + 1 + 4 + 4 = 10

proj_v(u) = (-6 / 10) * (-1, 1, 2, 2) = (-0.6, 0.6, 1.2, 1.2) ≈ (-0.5, 0.5, 1, 1)

b) Projection of v along u:

v . u = (-1 * 0) + (1 * 1) + (2 * 3) + (2 * -6) = 0 + 1 + 6 - 12 = -5

u . u = (0 * 0) + (1 * 1) + (3 * 3) + (-6 * -6) = 0 + 1 + 9 + 36 = 46

proj_u(v) = (-5 / 46) * (0, 1, 3, -6) = (0, -0.11, -0.33, 0.67) ≈ (0, 0, 0, 0)

The projection of vector u along v is approximately (-0.5, 0.5, 1, 1), indicating how much of u aligns with the direction of v. On the other hand, the projection of vector v along u is (0, 0, 0, 0), suggesting that v is orthogonal or perpendicular to u. Calculating projections helps in understanding the relationship between vectors and can be useful in various mathematical and engineering applications, such as solving systems of linear equations, analyzing vector spaces, or performing vector-based computations.

Answers

The issue of encrypting a set of files with a technique that processes files individually and requires a more complex approach than matching one file to one thread is most closely aligned with the issue of data splitting in multi-core programming.

Data splitting involves dividing a large data set into smaller chunks that can be processed by different threads in parallel. In the case of file encryption, the different data files are different sizes and require a more complex approach than simply matching one file to one thread. Instead, the files must be split into smaller chunks that can be processed in parallel by multiple threads.

By dividing the data into smaller chunks, the processing workload can be distributed across multiple cores, enabling faster processing times and better utilization of the available resources. However, this requires careful management of the data chunks to ensure that they are processed correctly and that the encrypted files are reassembled correctly.

Overall, data splitting is an important issue in multi-core programming that requires careful consideration and management to ensure that processing tasks are executed efficiently and correctly.
