Your instructions were to
define, describe and
identify the computer
vocabulary from the text
provided, “Computers
Inside and Out.”
And some vocabulary, you
just had to figure out on your
own….
Input
 Input is information that goes IN to a computer.
 What are some things you can input into a computer?
 Give some examples of input devices…
Output
 Output is information that comes OUT of a computer
 Name some examples of output devices…
Storage
 Storage is where data is kept.
 Name some examples of storage devices…
Processing
 Computer Processing is the execution of computer
instructions. When a computer processes a software
program, it performs the commands written in the
programming code.
 In a computer, where does the processing take place?
 CPU (Central Processing Unit)
Software
 Computer software is any set of machine-readable
instructions that tells a computer's what to do.
Computer programs are software.
 The term is used to contrast with the computer
hardware that carries out the instructions.
 Hardware and software require each other and neither
has any value without the other.
Hardware
 Hardware refers to the physical parts of a computer
system.
 Some basic computer hardware includes the
motherboard, CPU, RAM, hard drive, and BIOS chip.
Programming
 Programming is the act of creating the set of
instructions (program) that tell a computer what to do.
 Name some examples of a computer program…
Random Access Memory
 RAM (Random Access Memory) stores data and
programs on a temporary basis. When you turn off the
computer, the data in RAM disappears.
 The amount of RAM you have affects how fast your
computer can process information.
Hard Drive
 The hard drive is what stores all your data on a
permanent basis. When you turn off your computer,
data on your hard drive is unaffected.
 A typical hard drive is only slightly larger than your
hand, yet can hold over 100 GB of data.
Read Only Memory
 Read Only Memory holds data that is permanent and
cannot be changed.
 ROM is used to hold the instructions that the
computer needs to boot up, before the system software
loads.
 What is an example of a ROM chip?
 BIOS (Basic Input/Output System).
Data
 Computer data is any information processed or stored
by a computer.
Media
 Media refers to anything that holds information
(data). A book is media. A Blu-Ray disc is media.
 Can you give some examples of computer media?
 … Hard drives, removable drives (such as Zip disks),
CD-ROM or CD-R discs, DVDs, flash memory, USB
drives.
Microprocessor
 A microprocessor is a small chip inside a computer or
other electronic device, that receives input, processes
it, and produces output.
 What is the main processor (the “brain”) of a computer
called?
 CPU (Central Processing Unit)
Binary
 Binary (or "base-2") is a numeric system that only uses
two digits — 0 and 1.
Bit
 A bit (short for "binary digit") is the smallest unit of
measurement inside a computer. It contains a single
value of 0 or 1.
 Bits are often grouped together in 8-bit clusters called
bytes.
Pixel
 The term pixel is actually short for "Picture Element."
These small little dots are what make up the images on
computer displays,
 A computer screen’s resolution is measured in pixels.

Answer review
What are considered to be the
true ancestors to today’s
computer?
 Some of the ancestors or today’s computers include:
 The abacus
 Mechanical calculators
 The Analytical Engine
Who invented the Analytical
Engine?
 Charles Babbage
Who programmed the Analytical
Engine?
 Ada Byron King (the Countess of Lovelace)
programmed the Analytical Engine. She is considered
the mother of computer programming.
What is hardware?
 Hardware refers to the physical parts of a computer
system.
 Some basic computer hardware includes the
motherboard, CPU, RAM, hard drive, and BIOS chip.
What is software?
 Computer software is any set of machine-readable
instructions that tells a computer's what to do.
Computer programs are software.
 The term is used to contrast with the computer
hardware that carries out the instructions.
 Hardware and software require each other and neither
has any value without the other.
What is a microprocessor (CPU)?
 The microprocessor is the “brain” of the computer. The
Central Processing Unit (CPU) controls what a
computer does.
What is an input device?
List an example.
 Any device that lets you put data IN to a computer.
 Examples include:
 Keyboard
 Mouse
 Digital Camera
 Thumb drive
 CD
What does ROM stand for?
 Read Only Memory
 This is information that cannot be changed.
What does RAM stand for?
 Random Access Memory
 The computer uses RAM for temporary storage of
information.
What do you call the place where
you store information that will be
used again and again?
 . Long-term storage
What devices are used for long
term storage?
 ROM (Read Only Memory)
 Hard drive
 Thumb drive
 CDs/DVDs
What is output? Give example of
output devices.
 Output is any data that comes OUT of a computer
 Examples include:
 Printer
 Monitor
 Sound from the computer speakers
 MP3 file
What is binary code?
 Binary (or "base-2“) code is a numeric system that
only uses two digits — 0 and 1.
What are the 2 numbers in that
computer code, and what do they
represent?
 The numbers Zero and One
 Zero represents “off” and One represents “on”
What is a bit?
 A bit (short for "binary digit") is the smallest unit of
measurement inside a computer. It contains a single
value of 0 or 1.
 Bits are often grouped together in 8-bit clusters called
bytes.
What is a pixel?
 The term pixel is actually short for "Picture Element."
These small little dots are what make up the images on
computer displays,
 A computer screen’s resolution is measured in pixels.

discussed in the article?
 Kilobyte
 Megabyte
 Gigabyte
 Terabyte
