Answer:
a. True
Explanation:
A computer can be defined as an electronic device that is capable of receiving of data in its raw form as input and processes these data into information that could be used by an end user. Computers can be classified on the basis of their size and capacity as follows;
I. Supercomputers.
II. Mainframe computers.
III. Mini computers.
IV. Micro computers.
Mainframe computers were developed and introduced in the early 1950s.
Mainframe computers are specifically designed to be used for performing multi-programming because they are high-performance computers with the ability to handle multiple users. As a result, it simply means that mainframe computers can be used to effectively and efficiently perform the work of over one hundred (100) users at a time on the computer. Some examples of mainframe computers include the following; IBM Es000 series, CDC 6600 and ICL39 Series.
Furthermore, mainframe computers are mostly or commonly used by large companies, business firms or governmental institutions for performing various complex tasks such as census, financial transactions, e-commerce, data sequencing, enterprise resource planning, etc.

Answer: keeps confidential documents secure,
displays a GUI, allocates the computer's resources, and retrieves files
Explanation:
The operating system can be defined as the software installed in the system that provides the information and services to the users by controlling the hardware, software resources, and regulates the computer programs. It runs the applications and programs in the system, displays the graphic user interface for the services, stores, manipulates, and retrieves files. It prevents the unauthorized access to the data and programs by using passwords thus provides the security to the system and documents.
1.
name = input("Enter your name: ")
num1 = int(input("Hello "+name+ ", enter an integer: "))
num2 = int(input(name+", enter another integer: "))
try:
if num1 % num2 == 0:
print("The first number is divisible by the second number")
else:
print("The first number is not divisible by the second number")
except ZeroDivisionError:
print("The first number is not divisible by the second number")
try:
if num2 % num1 == 0:
print("The second number is divisible by the first number")
else:
print("The second number is not divisible by the first number")
except ZeroDivisionError:
print("The second number is not divisible by the first number")
2.
import random, math
num1 = float(input("Enter a small decimal number: "))
num2 = float(input("Enter a large decimal number: "))
r = round(random.uniform(num1, num2), 2)
print("The volume of a sphere with radius " + str(r) + " is " + str(round(((4 / 3) * math.pi * (r ** 3)), 2)))
I hope this helps!
