Answer:
The answer is below
Explanation:
Considering the situation and the available options above, the following configurations are needed for internet communications:
B. DNS server address: this matches the domain name to the IP address of a website such that browsers can bring internet resources.
C. Default gateway address: this uses the internet protocol suites and serves as a router to other networks in the absence of other route specifications that could match the destination IP address of a packet.
G. IP address including a subnet mask (IPv4) or subnet prefix length (IPv6): this is used by the internet-connected device to receive messages.
The internet's data pathways rely on what kind of hardware device to route data to its destination?
servers
routers
IP addresses
ISPs
Answer:
Routers
Explanation:
Essentially a router is a device used in networking that route packets of data from one computer network to another.
Answer:
routers
Explanation:
Routers are hardware devices that route the data from place to place. Data "hops" from one router to another until it reaches its destination. ISPs and IP addresses are not hardware devices. Servers are hardware devices but do not route data.

If you were driving the blue Prius in the situation pictured above, explain why the red Mustang should be given right-of-way at this intersection.
Answer:
The red Mustang should be given the right-of-way at this intersection because:
The red Mustang arrived first before the blue Prius and is closer to the stop sign before the arrival of the blue Prius. This implies that the red Mustang must have waited for its turn, unlike the blue Prius that just arrived at the intersection.
Explanation:
Traffic laws, regulations, and IPDE defensive driving strategy require that drivers always give way to the vehicle that arrived before them at an intersection. Assuming that multiple vehicles reach the intersection simultaneously, then the vehicle must be given the right-of-way. Alternatively, the traffic lights at the intersection should be obeyed and be allowed to regulate the movement of vehicles. IPDE defensive driving strategy requires drivers to be watchful of their driving spaces to determine the appropriate time to move.
If Scheme were a pure functional language, could it include DISPLAY ? Why or why not?
Answer:
When Scheme is a pure functional language, it cannot include the function DISPLAY. Since the pure functional languages will return the same value whenever the same expression is evaluated, and the DISPLAY would be the output and thus it cannot be part of the purely functional language. Thus in the pure functional language we can evaluate the expressions with the same arguments and it returns the same value since there is no state to change.

why do we need vector graphics for creating logo
Answer:
hope it will help uplease mark brillient
Answer:
So we can maintain high quality designs at any graphic scale.
Explanation:
Unlike other graphic formats which simply define colors for fixed pixels, vector graphics define points and shapes (vectors) which are then used to draw the graphic at the desired and appropriate resolution.
Our graphic can look good at any resolution, no matter how large it gets. If we take a png or jpg file and make it extremely large, you'll notice the image begins to get blurry, because the pixels are being stretched and colors are being predicted or matched for the larger scale.

[OPINION]
First one is correct.
For the second one, I think the leader should accept the invitation and forward it to the entire team. [As the team experienced success due to group work, so every team member should be invited... as the success was a result of the hardwork of every member]
About the third one, I think it depends on the person so you may be correct. But, if I was asked to choose I would have been chosen.... rational approach
This is just my opinion. Hope it helps you:)
1. For this assignment you will print the steps for 8-bit by 8-bit multiplication.
2. Your program should read in two unsigned numbers from stdin, the first being the multiplicand and the second being the multiplier. Your program should verify that both values are within the range 0 to 255. If not, the program should print an appropriate error message and exit.
3. Your program should then initialize the simulated registers and echo the input values in decimal and also in binary.
4. Then your program should illustrate the eight steps required for multiplication using the same type of step diagrams as given in the lecture notes.
5. Finally, your program should print a check section that shows a summary of the multiplication in binary as well as in decimal. See the example below.
6. You may write your program in C, C++, or Java. If you choose to work in C, here is an example function that will allow you to represent an n-bit value within an int data type and print out the binary value in "length" bits. It uses the shift right operator and the bitwise and. (You can also choose to use unsigned int as the data type; since you are using only the lower 8 of the 32 bits in an int, there will be no apparent difference between using int and using unsigned int. However, if you choose to use char as the data type, you should use unsigned char to ensure that the compiler generates logical rather than arithmetic shifts.)
void prt_bin( int value, int length ){
int i;
for( i=(length-1); i>=0; i--){
if((value>>i)&1)
putchar('1');
else
putchar('0');
}
}
For example, if you declare acc as an int, then you could call prt_bin(acc,8) to print the 8-bit value in the accumulator.
You should format your output to exactly match the output below. 10% of the grade will be awarded for following the same format.

multiplicand: 33

c)what formula would be in the cell E2
Excel will generally be able to handle any properly-input mathematical formula, if valid operators are used. Commonly used operators include "+" (addition), "-" (subtraction), "*" (multiplication) and "/" (division). (Microsoft has a complete list of valid operators to be used in Excel formulas on the Office website). Here are some examples of formulas using common operators:
Formula Description
=C2-B2 Subtracts contents of B2 from contents of C2
=C2/B2 Divides contents of C2 by contents of B2
=(B2+C2+D2)/3 Adds contents of B2, C2, and D2 and divides result by 3
After hitting "Enter", the cell will display the calculated value, while the formula bar will still display the formula. (Note: Always hit “Enter” when finished entering a formula, manually. If you click off the cell, the cell you click to will be added to your formula.)Formulas
Formulas in Excel are basically mathematical expressions that use cell references (e.g., “A5”,” D17”) as arguments. For example, a formula that adds the contents of cell E5 and E6 could be written as follows:
= E5+E6
(Note: all formulas in Excel need to be preceded by an “=” sign.) If the values contained in E5 and E6 are 6 and 11, respectively, the formula will produce 17 as the value it displays. If you change E5 to 7, the result will automatically change to 18.
Example
Let's say you were putting together an office supply order, and you wanted to keep track of much you were spending. You could put together a spreadsheet like the one below, with the list of items to be purchased, their unit prices, the number of each item ordered, and the total spent for each. It would make sense to enter the things you know in advance (like the price of individual items and the number ordered), but you could let Excel calculate the totals for you. For the first item listed below (pencils), this could be done by making the value of the total price (cell D2), the value of the unit price (held in cell C2) multiplied by the number of items ordered (held in D2). This formula would be written "=B2*C2".
Once you click "OK", your completed formula will be input into the cell.
Copying and pasting formulas
Often, you will need Excel to do a series of similar computations, where the only things that will change are the cells used as arguments. For instance, in the example above, you would probably like Excel to calculate the Total Price for each item in the order. You could re-input the same formula used to get the total price for pencils in each cell in that row, just changing the cells referenced (i.e. "=PRODUCT(B3:C3)", "=PRODUCT(B4:C4)", etc.), but Excel has simpler method for this. If you have multiple cells in the same row or column that need to do the same computation, you can simply copy the value in the cell you entered a formula, and then paste it into the subsequent cells. Excel will then automatically adjust which cells are included in the formula, based upon which cell the formula was pasted to. So, if the original formula entered in D2 was "=PRODUCT(B2:C2)", the formula pasted into D4 would be "=PRODUCT(B4:C4)"
More simply, if you have a formula you want repeated in a number of directly adjoining cells, you can just click and drag the bottom right corner of the cell with the original formula (see image below) onto the cells you want the same formula entered, and Excel will automatically copy and paste the formula for you, with appropriate adjustments made to the cell numbers in the formula.
After selecting "PRODUCT" and clicking OK, you will get another dialog box, that allows you to select the cells to be multiplied. You can do this for individual cells, by selecting cells separately in the "Number1" and "Number2" boxes shown below, or by selecting an array of cells, by clicking and dragging on the range cells you want to use on the spreadsheet, itself. (Note: if you try to enter a formula in a cell using the Insert Formula button and there are adjacent cells with numbers, Excel will often select those cells automatically, so make sure the cells selected in the dialog box are the correct ones.) Excel also has built-in functions that can do a lot of useful calculations. These are most easily accessed by hitting the Insert Function button, which is represented by the “fx” symbol next to the formula bar. For example, instead of entering the formula shown above, the same result could have been achieved using the built-in "PRODUCT" function by clicking in cell D2 and hitting the Insert Formula button. This would give a dialog box like the one shown, below.
After choosing “PRODUCT” and pressing OK, a new dialogue box will appear where you may choose which cells should be multiplied. By selecting particular cells in the “Number1” and “Number2” boxes as shown below, you can do this for specific cells.
What is the formula would be in the cell E2Additionally, Excel contains many useful built-in functions that can perform calculations. The button shown by the “fx” sign next to the formula bar, “Insert Function,” can be used to access these the simplest way by clicking it.
Make sure the cells selected in the dialogue box are the proper ones because if you try to insert a formula in a cell using the Insert Formula button and there are adjacent cells containing numbers. Excel will frequently select those cells automatically.)
Therefore, by deciding a range of cells on the spreadsheet itself by clicking and dragging on the desired range of cells.

Suppose we can buy a chocolate bar from the vending machine for $1 each. Inside every chocolate bar is a coupon. We can redeem six coupons for one chocolate bar from the machine. This means that once you have started buying chocolate bars from the machine, you always have some coupons. We would like to know how many chocolate bars can be eaten if we start with N dollars and always redeem coupons if we have enough for an additional chocolate bar.For example, with 6 dollars we could consume 7 chocolate bars after purchasing 6 bars giving us 6 coupons and then redeeming the 6 coupons for one bar. This would leave us with one extra coupon. For 11 dollars, we could consume 13 chocolate bars and still have one coupon left. For 2 dollars, we could have consumed 14 chocolate bars and have two coupons left.Write a program that inputs a value for N and outputs how many chocolate bars we can eat and how many coupons we would have left over. Use a loop that continues to redeem coupons as long as there are enough to get at least one chocolate bar.
Answer and Explanation:
Using JavaScript:

Add a function to problem to display the last name and highest, last name and lowest and average exam score. Hint: for highest initialize a variable to 0 (high_var). If the array value is higher than the high_var then set high_var to the array value and set high_index to the position of the array. Proceed through the array until you get to the end. Do the same for finding the lowest using low_var set to 999 (higher than the highest value). For the average score, sum all the exam scores as you proceed through the loop. Use a for loop to go through each occurrence of the arrays. Note you can do all this with one for loop but if it makes more sense to you to use multiple for loops that is ok too.

Explanation:
During the data transmission there are chances that the data bits in the frame might get corrupted. This will require the sender to re-transmit the frame and hence it will increase the re-transmission overhead. By considering the scenarios given below, you have to choose whether the packets should be encapsulated in a single frame or multiple frames in order to minimize the re-transmission overhead.
Justify your answer with one valid reason for both the scenarios given below.
Scenario A: Suppose you are using a network which is very prone to errors.
Scenario B: Suppose you are using a network with high reliability and accuracy.
The packets would be encapsulated in single frame in scenario A. In scenario B, it should be in multi frames.
In scenario A, given that this network has been said to be prone to error, the packets should be encapsulated in single frames.
The reason for this is because, using a single frame helps to decrease error. We have been told already that it is prone to error. If you use the multi frame, there would be very high likelihood of errors occurring.
In scenario B, given that the network is accurate and very reliable, the best packet is the multi frame.
It would give a quicker transmission and the likelihood of errors occurring is also low.

Packed BCD ( Binary coded decimal) is type in which each decimal digit is represented by 4 bits ( 1 nibble) . For Example : 14 will be shown as 0001 0100 in packed BCD form. Unpacked BCD is type in which each decimal digit is represented by 8 bits ( 1 byte).
cpp Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Ex: If the input is:
Answer:
#include <iostream>
int main() {
// The length of the list
int l;
// The array containing the numbers
int *list;
// Threshold, last value in array
int thresh;
// Read in first value and create an array with the size of that value
scanf("%d", &l);
list = (int*) malloc(l * sizeof(int));
for(int i = 0; i < l; i++) {
scanf("%d", &list[i]);
}
thresh = list[l - 1];
// Print the values
for(int i = 0; i < l - 1; i++) {
if (list[i] <= thresh) {
printf("%d ", list[i]);
}
}
printf("\n");
free(list);
}
Explanation:
The program assumes at least two values are provided. The length of the list and the threshold.
We first read in an integer, and find out how many more integers we need to read. We create an array with the appropriate size, and loop through to fill the array with values. We know the last value is the threshold, and so we do one more loop to compare the values in the array with the threshold.
