Chapter 2 The Visible Computer Flashcards
A mathematician in the 19th century, considered the father of the computer, thought of making machines that would do calculations mechanically, so the numbers would always be right.
Charles Babbage
What is an electronic device that can perform calculations, has an Operating System (OS), and is used for various tasks?
A Computer
Which of the following does NOT do specific computing jobs, focusing on a single task or set of similar tasks?
a. Digital Clock
b. Point of Sale (POS) system
c. Digital Camera
d. A Mouse
D. Mouse
What is the earliest mass-production car with a central processor chip for added performance?

What are the 3 major components of a modern computer?
Hardware, Operating System (OS), and Applications
Which major component of a modern computer is the physical stuff that you can touch or hold in your hand?
Hardware
Which major component of a modern computer controls the hardware and enables you to tell the computer what to do?
OS
Which major component of a modern computer enables you to do specialized tasks on a computer such as typing a letter, creating an email, play games?
Applications
What does UI stand for?
User Interface
What does GUI stand for?
Graphical User Interface
The operating system often appears as a collection of windows and little icons you can click or touch. Collectively these are called?
User Interface (UI)
The UI that offers images or icons to select (instead of making you type commands) is called a?
Graphical User Interface (GUI)
What are the 3 stages of a computer’s computing process?
Input > Processing > Output
What stage of a computer’s computing process that tells the hardware to do what you requested is called?
Processing
What stage of a computer’s computing process is where you start the action by doing something such as clicking the mouse or typing on the keyboard?
Input
What stage of a computer’s computing process is where the computer has processed your request and it shows you the result by changing what you see on the display or playing a sound?
Output
What do you call the ‘heart’ of every computing device that handles most of the processing tasks? which is usually a single, thin wafer of silicon and tiny transistors.
Central Processing Unit (CPU)
In addition to the 3 computing processes, modern computing devices always have two other stages, what are they?
Data Storage and Network Connection
Fill in the blank: A _________________ often describes how one computer connects to one or more other computers.
Network Connection
Fill in the blank: ________________ means saving a permanent copy of your work so that you can come back to it later.
Data Storage - First, you tell the computer to save something. Second, the CPU processes that command and stores the data. Third, the computer shows you something, such as a message saying that the data is stored. Any work that you don’t save is lost when you turn the computer off or exit the application.
“Why should I care about the computing process?”, “Why does the process matter to Techs?”
Because the computing process applies to every computing device, it provides the basis for how every tech builds, upgrades, and repairs such devices.
By understanding both the components involved and how they talk to each other, you can work with any computing device.
Let’s recall the 9 steps that apply to most computers and computing devices when you want to get something done:
- Power up. Computers run on electricity.
- Processing parts prepare for action.
- You provide input.
- Processing parts process your command.
5.Processing parts send output information to your output devices.
6.Output devices show or play the results to you.
7.Repeat Steps 3–6 until you’re satisfied with the outcome. - Save your work.
- Power down the computer.
