The Hi-Fi modem company has designed a new frequency modulation that can transmit 38400 bits/sec. The baud rate is 4800. How many frequency levels can each interval have? 3. 4. Given a location with 7 bits what is the minimum and maximum value that it can hold A) As an unsigned location B) As a signed location
Next time you snap a picture, you realize you are capturing millions of pixels into a buffer. The buffer data is read and converted into JPEG in real time. Each pixel in that buffer is an unsigned int (four bytes ): Alpha, Blue, Green, and Red. Let us ignore alpha for now. As you know, a unsigned byte can have a value 0 to 255. In remote sensing jargons, it is called blue channel, green channel, and red channel. Each channel provides valuable information such as, say farm lands, forest fire, drought, landscape, diseases , If a pixel has a value (say in hex) = 0x00a1b1c1 , then 0xc1 is the red pixel, 0xb1 is the green pixel, 0xa1 is the blue and 00 is the alpha. #define RED 1 #define GREEN 2 #define BLUE 3 then, develop a function void calculateSum ( unsigned int *ptr , int count , unsigned char channel , unsigned int *sum, float *average ) { *sum = 0; if (channel == RED ) calculate sum and average for red channel else if (channel == GREEN )…
Please solve it correctly and please provide explanation of your answers. Please answer parts g, h and i. A PC and a Web Server are communicating over a TCP connection. The PC had started the three way handshake with the initial sequence number of 3069 . The Web Server's initial sequence number is 4830 . The window size of the PC is 815 bytes and the window size of the Web Server is 463 bytes. Using the third TCP handshake ack segment the PC sends the http request of the size 396 bytes to the Web Server. Then the Web Server answers with 3 segments containing the requested data. The first segment size is 42 bytes and the second segment size is 276 bytes and the third segment size is 146 bytes respectively. The PC receives all three segments within the timer. But unfortunately the second segment was corrupted. So the PC immediately sends an acknowledgement segment. Assume that the PC uses Selective Repeat/Reject ARQ. g) The second segment from webserver was corrupted. So the PC…
Used C PLUS PLUS LANGUAGE. all instructions are given in question. Kindly follow it. When a message is transmitted in secret code over a transmission channel, it is usually sent as a sequence of bits, that is, 0s and 1s. Due to noise in the transmission channel, the transmitted message may become corrupted. That is, the message received at the destination is not the same as the message transmitted; some of the bits may have been changed. There are several techniques to check the validity of the transmitted message at the destination. One technique is to transmit the same message twice. At the destination, both copies of the message are compared bit by bit. If the corresponding bits are the same, the message received is error-free. Response Required: Write a program to check whether the message received at the destination is error-free. For simplicity, assume that the secret code representing the message is a sequence of digits (0 to 9) and the maximum length of the message is 250…
This is what my professor said: Items are 4 bytes, pages are 2k, so ~512 items fit on a page. Even if we start in the beginning of a page, the first access will be a miss followed by ~200 hits, then a TLB miss followed by ~500 hits, so the hit rate is ~100%5. Page size 512 means 9 bits of offset and 7 bits of VPN. The offset is just the decimal version of 1 0111 0111 [unsigned] which is 375The offset is 0011 100 which is 28. Is he correct?
Question: The Enigma device has to be resolved by Alan Turing and his team. You have been chosen as one of the smartest minds in the world. The device is producing codes like this; Incoming stream: HHLLHLHLL ——> the expected output: 12543761098 Incoming stream: LLHLLHLL ——> the expected output: 321654987 Incoming stream: HHHHLLLL ——> the expected output: 123498765 Incoming stream: LHLHHH ——> the expected output: 2143567 Alan says "No output digit repeats itself!". Write a full C code to decrypt this ciphered messages. You are supposed to use stack/s as a data structure for this solution. No stack answers will not be graded.
A messaging system reads message as 4-digit positive integer d1d2d3d4 and stores encoding of the message e1e2e3e4 for security reason. The encoding process is as follows: ei = (di+i) mod 3 For example, if message is 4590, the encoded message is 2101. Read any arbitrary message and display the encoded message in the following format: Original message = Encoded message = language : C

An analog signal having frequency as 6,70 KHz is digitized and stored in a file. If the total time of the signal is 24 min and the file size is 3,32 Mbit , which answer is correct? O a. Bit = 6 bits Data Rate = 40,2 Kbps O b. Bit = 8 bits Data Rate = 107,2 Kbps O c. Bit = 3 bits Data Rate = 221,5 Kbps O d. Bit = 7 bits Data Rate = 93,8 Kbps O e. Bit = 7 bits Data Rate = 80,4 Kbps
You are working on a project to build a temperature control system for an industrial machine. The machine should only operate between positive 20-150 Fahrenheit, but we need to show the operator the temp range negative 20 through positive 300. 1. What level of numeric precision can we get using only a single byte of memory? 2. Using the same project as question #1. What binary number would represent positive 20 degrees?
Suppose Alice and Bob are going to communicate using AES in CBC mode. Unfortunately Alice's message length (in bytes) is not a multiple of 16. Suppose the last block of her message is just a single zero byte. How can she pad out the last block so that she can use CBC mode? Since this needs to be a reversible operation, how does Bob recognize the padding and remove it?
The token bucket algorithm is a popular method for traffic shaping. A computer uses a token bucket with acapacity of 400 megabytes (MB) and a rate of 10 MB/sec. The computer continuously generates20 MB/sec for transmission from time 0. Assume the bucket’s water level is 200 MB at time 0.1a. How long will it take to send 1000 MB? Show the steps.1b. Draw a figure showing how the bucket’s water level evolves
