Answer:

d. Mainframes came before minicomputers, which led to the development of microcomputers.

Explanation:

The first mainframe was introduced in 1951: The UNIVAC (UNIVersal Automatic Computer I): large computer systems, for general purpose, with hundreds of users (separated from the computer) and fast computations, typically deployed by large business, industry, and government organizations.

The minicomputers are another class of computers that start to evolve since the late of the 1950s and the beginning of 1960s (like LINC, PDP-1, among many others), and focused on to have a more direct contact with the user or programmer, and because of this, it is said that minicomputers were the first 'personal' computers. They were cheaper than mainframes and with less memory capacity.

Finally, the microcomputers appeared around the beginning of 1970s (Micral), and sometime later (Altair 8800, Apple II) and were firstly used by hobbyists and computers enthusiasts. The term microcomputers have been supplanted nowadays by 'personal computers'.

Answer:

The solution code is written in Python.

def removeAdoptedDog(dog_dictionary, adopted_dog_names):
for x in adopted_dog_names:
del dog_dictionary[x]
return dog_dictionary
dog_dictionary = {
"Charlie": "Male",
"Max" : "Male",
"Bella" : "Female",
"Ruby": "Female",
"Toby": "Male",
"Coco": "Female",
"Teddy": "Male"
}
print(dog_dictionary)
adopted_dog_names = {"Ruby", "Teddy"}
print(removeAdoptedDog(dog_dictionary, adopted_dog_names))

Explanation:

Firstly, let's create a function removeAdoptedDog() takes two arguments, dog_dictionary & adopted_dog_names (Line 1)

Within the function, we can use a for-loop to traverse through the adopted_dog_names list and use the individual dog name as the key to remove the adopted dog from dog_dictionary (Line 3). To remove a key from a dictionary, we can use the keyword del.

Next return the updated dog_dictionary (Line 5).

Let's test our function by simply putting some sample records on the dog_dictionary (Line 7 -15) and two dog names to the adopted_dog_names list (Line 19).

Call the function removeAdoptedDog() by passing the dog_dictionary and adopted_dog_names as arguments. The display result will show the key represented by the adopted_dog_names have been removed from the dog_dictionary (Line 21).
