A computer has 64 MB (megabytes) of memory. Each word is 4 bytes. How many bits are needed to address eath single word in memory? P5-1. Р5-2. How many bytes of memory are needed to store a full screen of data if the screen is made of 24 lines with 80 characters in each line? The system uses ASCII code, with each ASCII character stored as a byte.
By assuming that X is the last digit of your student number and 3X is a two digit number, consider memory storage of a 64-bit word stored at memory word 3X in a byte-addressable memory (a) What is the byte address of memory word 3X? (b) What are the byte addresses that memory word 3X spans? (c) Draw the number 0XF1234567890ABCDE stored at word 3X in both big-endian and little-endian machines. Clearly label the byte address corresponding to each data byte value.

Question #1: What patterns do you notice in the time series plot of average annual airfare from 2004 to 2018? (a. horizontal pattern, b. clear upward trend, c. clear seasonal effects, d. clear downward trend) 2) Use a simple moving average with n = 3 (3 years) to calculate a forecast for the average airfare in 2019. Question #2: What is the 2019 forecast for average airfare using the simple moving average technique? (Round to two decimal places) 3) Based on the predicted values up to 2018, calculate accuracy measures (MAE, MSE, RMSE, and MAPE) for the simple moving average method. Question #3: What is the MAE for the simple moving average method?(Round to two decimal places) 4) Use a simple…

practice converting visual data into binary and decimal. The graph paper tables below represent data in a visual format. Each table below is a visual represenatation of 8 bytes, one byte per row. Each column in the row represents a single bit. The final entry in the table is for the decimal number represented in the row and is not part of the byte. An example: |x||X| |X|| 42 Instructions 1. For table one take a pencil and draw a numeral using as much of the graph paper as possible. Mark any square that contains a line with a large X or fill in the square. 2. For table two draw an emoji with a pencil using the entire graph paper and mark squares that contain a line with a large X or fill in the blocks. 3. For an example of "drawing" refer to table three; it contains the letter 4. Convert the visibile bits (Marked with an X) to decimal on table three. Fill in the values in the space provided. 5. Convert the decimal numbers in table four to bits and fill in the correct bits on the graph…
Please help provide answers for the following questions 2-26. The following bytes (shown in hex) represent a person’s name as it would be stored in a computer’s memory. Each byte is a padded ASCII code. Determine the name of each person. (a) 42 45 4E 20 53 4D 49 54 48 (b) Write the Phrase in ascii : I will score an A grade 2-30. Perform each of the following conversions. For some of them, you may want to try several methods to see which one works best for you. For example, a binary-to-decimal conversion may be done directly, or it may be done as a binary-to-hex conversion followed by a hex-to decimal conversion.= _2: binary _10: decimal _16: hexadecimal (a) 517_10 = _____ _2 (b) 255_10 = _____ _2 (c) 101010001_2 = _____ _10 (d) 1010101000100111_2 = _____ _10 (e) 2547_10 = _____ _16 (f) 567_10 = _____ (BCD) (g) 275_16 = _____ _10 (h) 53_10= _____ _16 (i) A79_16 = _____ _10 (j) 3ED5_16 = _____ _10 (k) 1760_10 = _____ _16 (l) 38,218_10 = ______ _16 (m)…
