Answer:

Router

Explanation:

A router is a more complex device that usually includes the capability of hubs, bridges and switches. A hub broadcasts data to all devices on a network. This can use a lot of bandwidth as it results in unnecessary data being sent - not all computers might need to receive the data.

The Java compiler does not check for an ArrayIndexOutorBoundsException during the compilation of a program containing arrays. O

yulyashka [42]

Answer:

TRUE

Explanation:

Let us first understand what is an ArrayIndexOutOfBounds Exception.
As the name itself suggests the index for the array has gone out of bound (permissible value) and an exception (anamoly) is resulted.
So, it throws an error.
That means if an array, Employee of size n is defined then the permissible elements are Employee[0] to Employee[n-1]. If any negative index or with the index is greater than n-1 is tried to access it throws an error saying ArrayIndexOutOfBounds Exception.
In java, during the compilation of the program the compiler doesn't check for the ArrayIndexOutOfBounds Exception.It checks during running the program.
So, it is called a Runtime Exception.

To prevent replay attacks, authentication protocols create a number that will be used only once. The number is called a _____.

fgiga [73]

Authentication protocols are usually designed and configured to create a number that will be used only once, so as to prevent replay attacks in a computer network. Thus, this number is called a nonce.

Authentication work based on the principle of strategically matching an incoming request from an end user or electronic device to a set of uniquely defined credentials.

In an access control list (ACL), authentication and authorization is used to ensure an end user is truly who he or she claims to be, as well as confirming that an electronic device is valid through the process of verification.

In Cybersecurity, authentication protocols are usually designed and configured to create a nonce, which can be used only once, so as to prevent replay attacks in a computer network.

In conclusion, a nonce is used prevent replay attacks in a computer network because the number created by an authentication protocol can be used only once.

Suppose that a CPU scheduling algorithm favors those processes that have used the least processor time in the recent past. Why w

avanturin [10]

Answer:

I/O bound programs will be favored due to the CPU burst request of the I/O programs. This is because their CPU burst request is short and would release the CPU within a short period.

Due to the brief request time of the I/O programs on the CPU, CPU-bound programs will not be permanently starved. After a little while, CPU resources will be released to the CPU-bound programs for use.
