why must a satellite have distinct uplink and downlink frequencies.
Answer:
The reason that a satellite must have a distinct uplink and downlink set of frequencies is because they help avoid any type of interference that may occur. The uplink receives the signal and amplifies it so that it can be transmitted to another frequency (downlink).

Explanation:
Servers can be designed to limit the number of open connections. For example, a server may wish to have only N socket connections at any point in time. As soon as N connections are made, the server will not accept another incoming connection until an existing connection is released. Please write pseudo-code to implement the synchronization using semaphore.
Answer:
The pseudocode is as follows:
open_server()
connections = N
while (connections>0 and connections <=N):
if(new_client == connected):
connections = connections - 1
for i in 1 to N - connections
if (client_i == done()):
releast_client(client_i)
connections = connections + 1
Explanation:
One of the functions of a semaphore is that, it is a positive variable whose value will never fall below 1. It is often shared among threads in order to keep a process running.
Having said that, what the above pseudocode does is that:
Once the server is opened, it initializes the number of connections to N.
When a new client, the semaphore decreases the number of connections is reduced by 1.
Similarly, when an already connected client is done, the client is released and the number of connections is increased by 1.
This operation is embedded in a while loop so that it can be repeatedly carried out.
1. Create a Java program.
2. The class name for the program should be 'EncryptTextMethods'.
3. In the program you should perform the following:
* You will modify the EncryptText program created in a previous assignment (see code below).
* You should move the logic for encrypting text from the main method into a method named encryptString.
* The encryptString method should have a single String argument and return a String value.
1. Create a second method.
2. The name of the method should be decryptString.
3. In the program you should perform the following:
* The method should have a single String argument and return a String value.
* This method should reverse the encryption process by subtracting one from each character in the String argument passed to it.
* The return value should be the result of the decrypting process.
4.The program should read an input String using the Scanner method.
5. The input value should be passed to the encryptString() method and the encrypted string should be passed to the decryptString() method.
6. The program should output the input string, the encrypted string and the decrypted string.
// Existing Code
import java.util.Scanner;
public class EncryptText {
private static String encodeMessage(String message) {
//convert string to character array
char stringChars[] = message.toCharArray();
//for each character
for(int i=0; i< stringChars.length; i++) {
char ch = stringChars[i];
//if character within range of alphabet
if(ch <= 'z' && ch >= 'a') {
//obtain the character value
//add 1 to the integer value
//enter modulus by 26 since z will become a
//once again add the remainder to 'a'
stringChars[i] = (char)('a' + ((int)(ch - 'a') + 1) % 26 );
}
}
//construct the string message
return String.valueOf(stringChars);
}
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
System.out.println("Please enter text to encode: ");
String message = keyboard.nextLine();
message = message.toLowerCase();
System.out.println("Encoded: " + encodeMessage(message));
keyboard.close();
}
}
Answer:
Explanation:
The following code was written in Java and follows all of the instructions provided. Some instructions were most likely written incorrectly as following them made no sense and would not allow the program to run. Such as placing the main method code into the encryptString method. Since the code inside the main method needed to stay inside the main method for the program to function accordingly. The code that most likely needed to be moved was the EncryptText code to the encryptString method.
package sample;
import java.util.Scanner;
class EncryptTextMethods {
private static String encryptMessage(String message) {
//convert string to character array
char stringChars[] = message.toCharArray();
//for each character
for(int i=0; i< stringChars.length; i++) {
char ch = stringChars[i];
//if character within range of alphabet
if(ch <= 'z' && ch >= 'a') {
//obtain the character value
//add 1 to the integer value
//enter modulus by 26 since z will become a
//once again add the remainder to 'a'
stringChars[i] = (char)('a' + ((int)(ch - 'a') + 1) % 26 );
}
}
//construct the string message
return String.valueOf(stringChars);
}
public static String decryptString(String message) {
char stringChars[] = message.toCharArray();
String decrypted = "";
for (int x = 0; x < stringChars.length; x++) {
int charValue = stringChars[x];
decrypted += String.valueOf( (char) (charValue - 1));
}
return decrypted;
}
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
System.out.println("Please enter text to encode: ");
String message = keyboard.nextLine();
message = message.toLowerCase();
String encrypted = encryptMessage(message);
String decrypted = decryptString(encrypted);
System.out.println("Original Message: " + message);
System.out.println("Encrypted: " + encrypted);
System.out.println("Decrypted: " + decrypted);
keyboard.close();

In this assignment we are going to practice reading from a file and writing the results of your program into a file. We are going to write a program to help Professor X automate the grade calculation for a course. Professor X has a data file that contains one line for each student in the course. The students name is the first thing on each line, followed by some tests scores. The number of scores might be different for each student. Here is an example of what a typical data file may look like: Joe 10 15 20 30 40 Bill 23 16 19 22 Sue 8 22 17 14 32 17 24 21 2 9 11 17 Grace 12 28 21 45 26 10 John 14 32 25 16 89 Program details Write a program that: Ask the user to enter the name of the data file. Read the data from the file and for each student calculate the total of the test scores, how many tests the student took, and the average of the test scores. Save the results in an output file (e.g. stats.txt) in the following order: studentName totalScore numberOfTests testAverage Note that the average is saved with 2 decimal places after the decimal point. Validation: Make sure your program does not crash if a file is not found or cannot be open.
Answer:
In Python:
import os.path
from os import path
fname = input("Filename: ")
if path.exists(fname):
with open(fname) as file_in:
lines = []
for line in file_in:
lines.append(line.rstrip('\n'))
f = open("stat.txt","r+")
f.truncate(0)
f = open("stat.txt", "a")
f.write("Names\tTotal\tSubjects\tAverage\n")
for i in range(len(lines)):
rowsum = 0; count = 0
nm = lines[i].split()
for j in nm:
if (j.isdecimal()):
count+=1
rowsum+=int(j)
average = rowsum/count
f.write(nm[0]+"\t %3d\t %2d\t\t %.2f\n" % (rowsum, count, average))
f.close()
else:
print("File does not exist")
Explanation:
See attachment for explanation where comments were used to explain each line
For each student, the sum of the marks, total tests were taken and the average of marks is calculated and is stored in an output file, for example, stats.txt.
Python Code:The code in Python asks the user for an input file name. If the input file is not found an error is printed else the data in the file is processed further.
Try:
# take input file name
file = input('Enter name of the data file: ')
# open the input file
ip = open(file, 'r')
# store the lines from input file in a list
lines = ip.readlines()
# close the file
ip.close()
# open the output file
op = open('stats.txt', 'w')
# iterate over each line
for line in lines:
# split data using space as delimiter
data = line.split()
# get name
name = data[0]
# get marks and convert them to integer
marks = list(map(int, data[1:]))
# get sum of marks
total = sum(marks)
# get number of tests
length = len(marks)
# calculate average of marks
avg = total/length
# add the data to output file
op.write('{} {} {} {:.2f}\n'.format(name, total, length, avg))
# close the output file
op.close()
print('Stats have been save in the output file')
# catch FileNotFoundError
except FileNotFoundError:
# print error
print('Error: that file does not exist. Try again.')

An expression that returns a value is known as a
Answer:
In computer programming, a return statement causes execution to leave the current subroutine and resume at the point in the code immediately after the instruction which called the subroutine, known as its return address. The return address is saved by the calling routine, today usually on the process's call stack or in a register. Return statements in many languages allow a function to specify a return value to be passed back to the code that called the function.
An expression that returns a value is known as a function. Check more about function below.

Assume we have two lists, list A and list B. List A contains the numbers [20,10,20], while list B contains the numbers [40,10,30,20,40,30]. We choose one number from list A randomly and one number from list B randomly. What is the chance that the number we drew from list A is larger than or equal to the number we drew from list B
Answer:
5/ 18
Explanation:
Given :
List A: [20,10,20]
List B: [40,10,30,20,40,30]
Chance that number drawn from list A is larger than or equal to that drawn dlfrom list B.
If:
A = 20
B ≤ 20 : [10,20] = 2
A = 10
B ≤ 10 : [10] = 1
A = 20
B ≤ 20 : [10,20] = 2
Probability = Required outcome / Total possible outcomes
Hence,
required outcome = (2 + 2 +1) = 5
Total possible outcomes = 3C1 * 6C1 = (3 * 6) = 18
Hence,
chance that the number we drew from list A is larger than or equal to the number we drew from list B
= 5 / 18

You have one address, 196.172.128.0 and you want to subnet that address. You want 10 subnets. 1. What class is this address
Answer:
This address is by default a class c network
Explanation:
This IP address in this question is a class c network because it has 196 as its first octet. A class c network is one which has its first octet to be between 192 and 223. the class c network begins with a 110 binary. If ip is between 192 to 223 it belongs to this class. These first 3 octets are the representation of the network number in the address. Class c's were made to support small networks initially.
For this program you will build a simple dice game called Pig. In this version of Pig, two players alternate turns. Players each begin the game with a score of 0. During a turn a player will roll a six-sided die one or more times, summing up the resulting rolls. At the end of the player's turn the sum for that turn is added to the player's total game score If at any time a player rolls a 1, the player's turn immediately ends and he/she earns O points for that turn (i.e. nothing is added to the player's total game score). This is called "pig". After every roll that isn't a 1, the player may choose to either end the turn, adding the sum from the current turn to his/her total game score, or roll again in an attempt to increase the sum. The first player to 50 points wins the game

In Python:
import random
p1name = input("Player 1: "); p2name = input("Player 2: ")
p1score = 0; p2score = 0
playerTurn = 1
print(p1name+" starts the game")
roll = True
while(roll):
if playerTurn == 1:
p1 = random.randint(1,6)
print(p1name+"'s roll: "+str(p1))
if p1 == 1:
playerTurn = 2
roll = True
else:
p1score+=p1
another = input("Another Roll (y/n): ")
if another == "y" or another == "Y":
roll = True
else:
playerTurn = 2
roll = True
else:
p2 = random.randint(1,6)
print(p2name+"'s roll: "+str(p2))
if p2 == 1:
playerTurn = 1
roll = True
else:

another = input("Another Roll (y/n): ")
if another == "y" or another == "Y":
roll = True
else:
playerTurn = 1
roll = True
if p1score >= 50 or p2score >= 50:
roll = False
print(p1name+":\t"+str(p1score)+"\t"+p2name+":\t"+str(p2score))
Explanation:
Note that the dice rolling is simulated using random number whose interval is between 1 and 6
This imports the random module
import random
This line gets the name of both players
p1name = input("Player 1: "); p2name = input("Player 2: ")
This line initializes the scores of both players to 0
p1score = 0; p2score = 0
This sets the first play to player 1
playerTurn = 1
This prints the name of player 1 to begin the game
print(p1name+" starts the game")
This boolean variable roll is set to True.
roll = True
Until roll is updated to False, the following while loop will be repeated
while(roll):
If player turn is 1
if playerTurn == 1:
This rolls the dice
p1 = random.randint(1,6)
This prints the outcome of the roll
print(p1name+"'s roll: "+str(p1))
If the outcome is 1, the turn is passed to player 2
if p1 == 1:
playerTurn = 2
roll = True
If otherwise
else:
Player 1 score is updated
p1score+=p1
This asks if player 1 will take another turn
another = input("Another Roll (y/n): ")
If yes, the player takes a turn. The turn is passed to player 2, if otherwise
if another == "y" or another == "Y":
roll = True
else:
playerTurn = 2
roll = True
If player turn is 2
else:
This rolls the dice
p2 = random.randint(1,6)
This prints the outcome of the roll
print(p2name+"'s roll: "+str(p2))
If the outcome is 1, the turn is passed to player 1
if p2 == 1:
playerTurn = 1
roll = True
If otherwise
else:
Player 2 score is updated
p2score+=p2
This asks if player 2 will take another turn
another = input("Another Roll (y/n): ")
If yes, the player takes a turn. The turn is passed to player 1, if otherwise
if another == "y" or another == "Y":
roll = True
else:
playerTurn = 1
roll = True
If either of both players has scored 50 or above
if p1score >= 50 or p2score >= 50:
roll is updated to False i.e. the loop ends
roll = False
This prints the name and scores of each player
print(p1name+":\t"+str(p1score)+"\t"+p2name+":\t"+str(p2score))

a. RISC (Reduced instruction set computing) architecture has a set of instructions, so high-level language compilers can produce more efficient code
b. It allows freedom of using the space on microprocessors because of its simplicity.
c. Many RISC processors use the registers for passing arguments and holding the local variables.
d. RISC functions use only a few parameters, and the RISC processors cannot use the call instructions, and therefore, use a fixed length instruction which is easy to pipeline.
e. All of the above.
Answer:
e. All of the above.
Explanation:
An instruction set architecture (ISA) can be defined as series of native memory architecture, instructions, addressing modes, external input and output devices, virtual memory, and interrupts that are meant to be executed by the directly.
Basically, this set of native data type specifies a well-defined interface for the development of the hardware and the software platform to run it.
The two (2) main types of architectural design for the central processing unit (CPU) are;
I. Complex instruction set computing (CISC): it allows multi-step operation or addressing modes to be executed within an instruction set. Thus, many low-level operations are being performed by an instruction.
II. Reduced instruction set computing (RISC): it allows fixed length instructions and simple addressing modes that can be executed within a clock cycle.
All of the following statements are true about RISC (Reduced instruction set computing) because they are its advantages over complex instruction set computing (CISC);
a. RISC (Reduced instruction set computing) architecture has a set of instructions, so high-level language compilers can produce more efficient code.
b. It allows freedom of using the space on microprocessors because of its simplicity.
c. Many RISC processors use the registers for passing arguments and holding the local variables.
d. RISC functions use only a few parameters, and the RISC processors cannot use the call instructions, and therefore, use a fixed length instruction which is easy to pipeline.
The options that are true about RISC (Reduced instruction set computing) is; E: all of the above
We are dealing with instruction set computing which is a sequence of instructions, addressing modes, external input & output devices, virtual memory, and other interruptions that are designed to be executed by the user directly.Now, in architectural design meant for the central processing unit (CPU) the benefit of a Reduced instruction set computing (RISC) is that it is a type that allows for a fixed length of instructions with simple addressing styles that can be executed within a clock cycle.Looking at all the given options, we can say they are all true about RISC (Reduced instruction set computing) as they possess advantages over the other type of instruction set computing called complex instruction set computing (CISC).Read more about instruction set computing at; https://brainly.com/question/17493537
