Answer:
Physical and data link layer.
Explanation:
The ethernet cable is used at the physical layer. The physical layer consists of hardware components. This layer is responsible for transmission of data bits between two nodes via a physical wire. The data link layer provides the means in which data packets are transmitted from one node to another.
Suppose two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, the packets would be sent from computer A to computer B if computer B is free if not it would wait until computer B is not transmitting before it can start sending data packets to computer B.
Answer: Network access control (NAC)
Explanation:
The solution that should be used is the network access control. Network access control helps in keeping devices and users that are unauthorized out of ones private network.
In this case, since one will like to prevent the laptops from connecting to the network unless anti-virus software and the latest operating system patches are installed, then the network access control can be used. One can only give access to the device that it wants to give access to and prevent others from connecting.
Answer:
Columns
Explanation:
A spreadsheet may a explained as a tabular arrangement or arrays of cells which allows users to enter both numeric and string data for storage, manipulation and analysis. The spreadsheet program has both the vertical and horizontal cell arrangement with the vertical areas being reffered to as THE COLUMN which are labeled using alphabets arranged from A - AZ, AA - AZ, and so on to make up a total of 16384 columns on the Microsoft Excel spreadsheet program. Cells are located using a combination of column and row address. With row representing the horizontal area of the spreadsheet and labeled with digits. Therefore cells are usually refereed to as A1, (column A row 1) and so on.
Answer:
class OddNumber
{
public static void main(String args[])
{
int n = 1000; //Store 1000 in Variable n typed integer
System.out.print("Odd Numbers from 1 to 1000 are:"); // Print headline of output window
for (int i = 1; i <= n; i++) //For loop to go through each number till end
{
if (i % 2 != 0) //check if number is even or odd.Not divisible by 2 without reminder means it is odd number
{
System.out.print(i + " "); //print odd numbers
}
}
}
}
