Lesson 1 - Introduction to Computers and Systems Flashcards
Introduction to Computers and Systems
This is a set of interrelated components working together towards a common goal/ to achieve an outcome.
System
This is a collection of interrelated components that collect, store, process, and provide as output the information needed to complete the tasks.
System
This is known as the part of a larger system.
Subsystem
This divides a system into smaller subsystems and components.
Functional decomposition
This is a device that stores information for future use. It collects a set of instructions to process as an output needed to accomplish business tasks.
Computer
He is a mathematician, mechanical engineer, and philosopher from the UK who is known as the Father of Computer. He invented the computer to mechanize manual mathematical operations.
Charles Babbage
This is a simple mechanical computer designed in the 1820s, that can only do one mathematical operation (addition).
Difference Engine
This is a general purpose computer system that can do 4 mathematical operations (addition, subtraction, multiplication, division)
Analytical Engine
She worked with Charles Babbage in the Difference Engine and is known as the first programmer. She also came from the UK and is a mathematician and writer.
Ada Lovelace/ Augusta Ada King, Countess of Lovelace
From 1946-1959, the _______ generation of computers used vacuum tubes as the basic components for memory and CPU.
First Generation
This generation of computers used punched cards, paper tape, and magnetic tape for input and output.
First Generation
From 1959 to 1965, the __________ generation of computers used “transistors,” which consumed less power, was cheaper, and more compact and fast than the first generation.
Second Generation
From 1965 to 1971, the ____________ generation of computers used Integrated Circuits, which was made by Jack Kilby.
Third Generation
From 1971 to 1980. The _____________ generation of computers used “very large scale integrated circuits,” which made computers more affordable, compact, and reliable.
Fourth Generation
