zyde 10.14.1: iterating over a dictionary example: gradebook statistics. write a program that uses the keys(), values(), and/or items() dict methods to find statistics about the student grades dictionary. find the following: print the name and grade percentage of the student with the highest total of points. find the average score of each assignment. find and apply a curve to each student's total score, such that the best student has 100% of the total points.
Answers
To find statistics about the student grades dictionary, we can use the keys(), values(), and items() methods of the dictionary. Here's a step-by-step solution: Initialize a dictionary called "gradebook" with student names as keys and their corresponding grades as values.
To find the student with the highest total points, we need to iterate over the items of the gradebook dictionary and calculate the total points for each student. We can use a variable, let's call it "highest_points", to keep track of the highest total points found so far. Start with a value of 0.
Iterate over the items of the gradebook dictionary using the items() method. For each item, calculate the total points by summing the grades using the sum() function.

Why error occurs during transmission? Explain different types of errors with suitable examples. 5 (b) How do you detect error using CRC? Generate the CRC code for the data word 1101011011 The divisor is x4+x+1. 7
Answers
During transmission, errors occur due to a variety of factors such as atmospheric conditions, system malfunction, or network errors.
Different types of errors include Single Bit Error, Burst Error, and Burst Error Correction. Here are the different types of errors with suitable examples: Single Bit Error: It occurs when one bit of data is changed from 1 to 0 or from 0 to 1 in data transfer. This type of error is mainly caused by a small amount of interference or noise in the transmission medium. For instance, a parity bit error.Burst Error: It occurs when two or more bits are incorrect during data transmission. A Burst Error occurs when bits of data are lost or changed in groups, which can affect multiple data bits at once. It can be caused by signal loss or attenuation in fiber-optic cables. Burst Error Correction: To overcome the issue of Burst Error, Burst Error Correction is used. This method divides data into blocks to detect and fix errors. Reed-Solomon coding and Viterbi decoding are two types of burst error correction techniques. There are different techniques for error detection, and the Cyclic Redundancy Check (CRC) is one of them. CRC checks the checksum at the receiver's end to ensure that the data was not corrupted during transmission. To detect errors using CRC, follow these steps: Divide the data word by the generator polynomial. Generator polynomial: x4 + x + 1 Divide 1101011011 by x4 + x + 1 and find the remainder by using the modulo 2 division method.1101011011 10011- 10011000- 10011000- 10010100- 10010100- 10000001- 10000001- 1111100- 1111100- 1001The remainder of the above step is the CRC code of the data word, which is 1001. Therefore, the CRC code for the data word 1101011011 is 1001.

Answers
Version-controlled software is a system that tracks changes to files and directories over time. It allows multiple developers to collaborate efficiently by managing different versions of the codebase.
The trunk, or mainline, refers to the main branch of development. A branch is a separate line of development created from the trunk. Commit is the act of saving changes to the version control system. Merge combines changes from one branch into another. Check-in refers to saving changes to the central repository, while check-out retrieves the latest version from the repository.
Version-controlled software is a system that tracks changes to code and facilitates collaboration. The trunk, also known as the mainline, is the primary branch of development.

And in R2? And in R3? And in R4? Lines 1-4 initialize the input registers, while lines 5-12 generate the output of the function, and store the result in register R2. What Boolean function is this code trying to implement? Specifically, identity the two input registers and the Bcolean function implemented R2-R? (mystery Boolean function?) R?
Answers
a) The PC now needs 24 bits.
b) The IR now needs 32 bits.
c) The MAR now needs 24 bits.
d) The MDR now needs 32 bits.
e) The instruction fetch is unaffected.
After the code reaches the end, the following bits are held in the registers:
R1: 00000000
R2: 11111111
R3: 00010010
R4: 00010001
The code implements a bitwise XOR function on the values in R1 and R3 and stores the result in R2. The input registers are R1 and R3, and the Boolean function implemented is XOR.
a) With 16MB of memory, the PC now needs 24 bits to address every byte in memory.
b) The instructions are now 32 bits long, so the instruction register now needs to hold 32 bits to store the entire instruction.
c) The memory address register now needs 24 bits to address every byte in memory.
d) The memory data register now needs 32 bits to store the entire 32-bit instruction.
e) The instruction fetch is unaffected because the time taken to fetch an instruction depends on the clock speed of the processor and the memory access time, which are not affected by the change in memory size or instruction length.
The code initializes R1 and R3 with values 00000000 and 00010010, respectively. It then performs a bitwise XOR operation on the values in R1 and R3 and stores the result in R2.
The XOR function is a basic Boolean function that returns true (1) when the two input bits are different and false (0) when they are the same. Therefore, the input registers are R1 and R3, and the implemented function is XOR.

What is word wrapping?A section of text is divided into lines using line breaking, also referred to as word wrapping, in order to fit it into the available width of a page, window, or other display area.
When text is displayed, line wrap is used to continue on a new line when a line is full.
This allows each line to fit into the viewable window and eliminates the need for horizontal scrolling, allowing text to be read from top to bottom.
Word wrap is a function that most text editors, word processors, and web browsers include that, where possible, breaks lines between words rather than within words.
Word wrap eliminates the need to hard-code newline delimiters within paragraphs and enables flexible, dynamic text display that can accommodate displays of various sizes.

A programmer for a weather website needs to display the proportion of days with freezing temperatures in a given month.
Their algorithm will operate on a list of temperatures for each day in the month. It must keep track of how many temperatures are below or equal to 32. Once it's done processing the list, it must display the ratio of freezing days over total days.
Which of these correctly expresses that algorithm in pseudocode?
A.
numFreezing ← 0
numDays ← 0
FOR EACH temp IN temps {
IF (temp ≤ 32) {
numFreezing ← numFreezing + 1

Answers
Answer:
B.
Explanation:
The correct Pseudocode for this scenario would be B. This code makes two variables for the number of total days (numDays) and number of freezing days (numFreezing). Then it loops through the entire data set and checks if each temp is less than or equal to 32 degrees. If it is, it adds it to numFreezing, if it is not then it skips this step, but still adds 1 to the total number of days after each loop. Once the entire loop is done it prints out the ratio, unlike answer A which prints out the ratio for every iteration of the loop.
numFreezing ← 0
numDays ← 0
FOR EACH temp IN temps {
IF (temp ≤ 32) {
numFreezing ← numFreezing + 1
}
numDays ← numDays + 1

Point-to-point communication refers to the direct transmission of data between two endpoints, such as a client and a server. Synchronous communication means that the sender and receiver are in sync and exchange data in real-time.
This is commonly seen in protocols like TCP (Transmission Control Protocol), where data is sent and acknowledged in a synchronized manner. Asynchronous communication, on the other hand, allows for non-real-time, independent data transmission and processing between endpoints.
