what are the importance of web browser
Answers
Answer:
Web browser helps to access www.
Explanation:
A web browser is a software program that acts as a person's portal and portal to the Internet. It's easy to forget the browser's value now that it's so popular in our everyday lives. Users had to download software only to talk, watch videos, or play music until web browsers were invented.
Consider the regular expressions:
R1 = (01)* (0*1*) (10)
R2 = (101)* (01)*
R3 = (10) (01*)*(01)
R4 = 10(R2*)|R3
Recall that, for a list of regular expressions, the function getToken() returns the next token from the input that matches one of the regular expressions. If there is more than one match, the longest match is returned. If there is more than one longest match, the token with the longest match that appears first in the list is returned. If there is no match, ERROR is returned. If the function getToken() is called once on input 1000101, it will return:
a. R1
b. R2
c. R3
d. R4
e. ERROR
Answers
Answer:
c. R3
Explanation:
For R1;
there are 10 matches, after these 10 no matches occur again
for R2;
this also does not match more than 10 as we have in R1
for r3;
R3 has the longest match. Its matching can be done 1000101 times.
for r4;
The whole of r4 can be matched.
Error;
we cannot have an error because matches exist.
so in answer to this question we pick R3 as the solution because there are more than one longest march and the one returned in the list is that which appeared first. R3 came first
In this exercise we have to use computer knowledge to identify which is the correct sequence of code that best corresponds to the given question, in this way we have that the correct alternative is:
[tex]c. R3[/tex]
So analyzing the first alternative, we find;
For R1, there are 10 matches, after these 10 no matches occur again.
So analyzing the second alternative, we find;
For R2, this also does not match more than 10 as we have in R1
So analyzing the third alternative, we find;
R3 has the longest match. Its matching can be done 1000101 times.
So analyzing the fourth alternative, we find;
For R4, the whole of r4 can be matched.
So analyzing the fifth alternative, we find;
Error; we cannot have an error because matches exist.
So in answer to this question we pick R3 as the solution because there are more than one longest march and the one returned in the list is that which appeared first.

For this exercise, you are going to complete the printScope() method in the Scope class. Then you will create a Scope object in the ScopeTester and call the printScope.
The method will print the name of each variable in the Scope class, as well as its corresponding value. There are 5 total variables in the Scope class, some of which can be accessed directly as instance variable, others of which need to be accessed via their getter methods.
For any variable that can be accessed directly, use the variable name. Otherwise, use the getter method.
Sample Output:
The output of the printScope method should look like this:
a = 5
b = 10
c = 15
d = 20
e = 25
public class ScopeTester

public static void main(String[] args)
{
// Start here!

Write a program that would determine the day number in a non-leap year. For example, in a non-leap year, the day number for Dec 31 is 365; for Jan 1 is 1, and for February 1 is 32. This program will ask the user to input day and month values. Then it will display the day number day number corresponding to the day and month values entered assuming a non-leap year. (See part II to this exercise below).
Answers
Answer:
In Python:
months = ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"]
daymonths = [31,28,31,30,31,30,31,31,30,31,30,31]
day = int(input("Day: "))
month = input("Month: ")
ind = months.index(month)
numday = 0
for i in range(ind):
numday+=daymonths[i]
numday+=day
print(numday)
Explanation:
This initializes the months to a list
months = ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"]
This initializes the corresponding days of each month to a list
daymonths = [31,28,31,30,31,30,31,31,30,31,30,31]
This gets the day from the user
day = int(input("Day: "))
This gets the month from the user
month = input("Month: ")
This gets the index of the month entered by the user
ind = months.index(month)
This initializes the sum of days to 0
numday = 0
This adds up the days of the months before the month entered by the user
for i in range(ind):
numday+=daymonths[i]
This adds the day number to the sum of the months
numday+=day
This prints the required number of days
print(numday)

How should you schedule a meeting with someone in another time zone?
Answers
If you know what timezone they're in, try to work out what time in your own timezone your free, then tell the other person to do the same. Tell them what times in your timezone and the other can search up what the time is in their own timezone. If there is a specific time when you are both free, use that.
Ex:
You live in the U.S. but you have a meeting with someone in the U.K. You're only free at 4:00pm-6:00pm and they're only free from 10:00am-11:00am. 11:00am in England is 4:00pm in the U.S. so do at that time!

Assume the data link protocol used by NDAS has the following associated characteristics:
An 8-bit ASCII code is used. Each frame has a size (length) of 11936 bits. A half-duplex circuit with a speed of 1 million bits per second is used for transmission. There is a 30-millisecond turnaround time on the half-duplex circuit. Each frame contains 20 overhead (non-user-data) bytes. Assume that the probability of a frame requiring retransmission due to error in transmission is 1 percent. A millisecond is one-thousandth of a second. Also, 8 bits = 1 character = 1byte
Fill in the blanks
K= _________ bits per bytes
M=_________ bytes
C= _________ overhead bytes
Answers
Answer:
The transmission speed = 0.278 MB/s
Explanation:
K = 8 bits
M = 11936/8 bits = 1492 bits
transmission rate R = 1000000/ 8 = 125000 bps
overhead bytes C = 20
probability = 0.01
time T = 30 ms = 30 x10^-3 s
The data transmission speed formula = K(M-C)(1-p) / (M/R) + T
= 8( 1492 - 20)(0.99)/ (1492/125000) + 30 x10^-3
= 0.278 MB/s

For a company, intellectual property is any idea that the company wants to keep secret. Thus the correct option is A.
What is intellectual Property?The type of integrity is defined as "intellectual property" which includes intangible works developed by humans with an innovative and problem-solving approach.
These intellectual properties are protected by companies to avoid leakage of the secret of development as well as to avoid imitation of the creation. This protection of the intellectual property is legally bounded.
If any violation of this act has been noticed and found guilty will have to face consequences in terms of charges of violation as well as heavy penalties based on the type and importance of the work.
Therefore, option A any idea that the company wants to keep secret is the appropriate answer.

Modify the following code so that:

Based on the number of the randomly generated coins at the beginning,
let the computer determine whether Player 1 or Player 2 will be the
winner based on the winning strategy (by printing out the winner).
After deciding the supposed winner and loser, let the computer play
out both of the roles. For the winner, the computer should be applying
the winning strategy; for the loser, the computer should generate a
random amount of coins while following all the rules of the game
Rules of the game:
a) The game starts with 22 coins in a common pool
b) The goal of the game is to take the last coin
c) Two players take turns removing 1, 2, or 3 coins from the pool
d) A player can NOT take more coins than remaining coins in the pool
e) After each turn, the judge announces how many coins remain in the
pool

To generate random number from min to max, we make of the following syntax:
min + rand()%(max - min)
In this case:
[tex]min = 100[/tex]
[tex]max = 149[/tex]
So, we have:
100 + rand()%(149 - 100)
100 + rand()%49
