Answer:
C)
Explanation:
One principle that can improve the efficiency of I/O would be to move processing primitives into hardware. Primitives are a semantic value representing something else such as words or numbers within the programming language. By moving them into hardware they system is able to read them at a much faster speed making the I/O more efficient.
Options: True or false
Answer: True
Explanation:TCP(TRANSMISSION CONTROL PROTOCOL) is is an internet control protocol that allows Communication between internet users or computers by collecting and compiling packets of data and then sending such collected packets of data to the desired user.
Before using a TCP one must first create a connection which will enable it to effectively communicate with the other user.
TCP are established using sequence numbers which can be predicted by another party for their own personal gain.
Answer:
Following are the code to the given question:
public class BaseballPlayer//defining a class BaseballPlayer
{
BaseballPlayer(int numHits, int numRuns, int numRBIs)//defining a parameterized cons
{
}
}
Explanation:
Some of the data is missing, which is why the solution can be represented as follows:
In this code, a class BaseballPlayer is defined, and inside the class a parameterized constructor is defined that holds three integer variable "numHits, numRuns, and numRBIs".

Explanation:
Playfair cipher invented in 1854 by Charles Wheatstone was the first practical digraph substitution cipher. Lord Playfair promoted the use of the cipher, therefore it was named after him. Playfair cipher encrypts pairs of letters (digraphs) making it hard to break. Frequency analysis can still be undertaken but requires much more cipher text in order to work. It requires no additional equipment to operate and is very fast therefore it is to protect information during war. It was used by British forces in the Second Boer War and in World War I and during World War II by the Australians.
When the PT-109 American patrol boat, under the command of Lieutenant John F. Kennedy, was sunk by a Japanese destroyer, a message was received at an Australian wireless station in the morning of the 2 of August 1943 in Playfair code:
