Discuss the three basic tasks performed by computers
Computers can perform three basic tasks: arithmetic operations, logical operations, and storage and retrieval operations.
Computers can add, subtract, multiply, divide, and raise numbers to a power (exponentiation), as shown in these examples:
A + B (addition) 5 + 7 = 12
A ? B (subtraction) 5 ? 2 = 3
A * B (multiplication) 5 * 2 = 10
A / B (division) 5 / 2 = 2.5
A ^ B (exponentiation) 5 ^ 2 = 25
Computers can perform comparison operations by comparing two numbers. For example, a computer can compare x to y and determine which number is larger.
Computers can store massive amounts of data in very small spaces and locate a particular item quickly. For example, a person can store the text of more than one million books in a memory device about the size of his or her fist.
