C. used artificial intelligence so that the computers become reasonably intelligent all on their own
Third-generation computers were developed in the 1960s and marked a significant advancement in the development of computers. They were the first computers to use integrated circuits, which allowed for smaller and more powerful computers. Third-generation computers also featured the development of high-level programming languages, such as COBOL and FORTRAN, which made it easier for programmers to write and understand code. These computers also used magnetic tape and disks for storage, which were much more efficient than the punched cards used in earlier computers. Third-generation computers made use of artificial intelligence, which allowed them to perform tasks that required some level of independent thought and decision-making.

4.5 code practice phython code answers
Answer:
count = 0
data = input('Please enter the next word: ')
while data!= "DONE":
count = count + 1
print("#" + str(count) +": You entered the word " + data)
data = input("Please enter the next word: ")
print("A total of "+ str(count) + " words were entered.")
Explanation:
So the code is asking us to put in words from the user and then it will count those words in total.
so first we want the code to start from 0 to get an accurate count
count = 0
boom, first line.
second you will ask the user to input a word with a data string on it to then have it stored
data = input('Please enter the next word: ')
now if the user enters DONE the code will know to stop and give the total
while data != "DONE":
then we will have the code count the words we inputed,
count = count + 1
next we want to know how many words we put in "the whole point of the code.
print("#" + str(count) +": You entered the word " + data)
the data is very important
if the user didnt enter DONE we want the code to continue so we ask the user to enter another word
data = input("Please enter the next word: ")
now we do the same thing as the code before, now we show how many words were entered in total
print("A total of "+ str(count) + " words were entered.")

This is so that other jobs can't interfere with the job that is done as even the printing queue operates on the first Attend, First Wait algorithm, which requires the queue waiting and printing services to go through numerous other procedures before the service provided to print. Additionally, since the job with printing must save the data on the disk, there is a chance that doing so will quickly and randomly alter the disk's content.
