TODAY’S AGENDA:
BASIC INFORMATION TECHNOLOGY VOCABULARY
• Computer
• Hardware
• Motherboard
• CPU and Memory
• Peripheral Devices
• Software
• Operating System
• Directories
• Applications
OBJECTIVE
Getting to know the inside of your computer.
COMPUTER
We use them everyday, but what are they? What was the
inspiration behind their invention?
A computer is a piece of technology based on the human
brain.
HARDWARE VERSUS SOFTWARE
The hardware of a computer is its physical or permanent
equipment (Body).
 EXAMPLE: motherboard, CPU, memory chips, peripherals
Software is a set of instructions that directs the computer to
accomplish a task (Thoughts).
 EXAMPLE: Operating systems, Applications
A CD is hardware, but a file on a rewritable disk containing
instructions is software. The software (program) might be
on the disk today but erased tomorrow when a new
program is written on the disk.
It is clear that the CD is permanent and the software is
temporary.
MOTHERBOARD
The motherboard is the most complicated piece of
equipment inside the computer.
Some of the items housed by the motherboard include:
CPU (Central Processing Unit)
RAM (Random Access Memory) Chips
Cache Memory - controls memory access speed
BIOS (Basic Input / Output System) Chip - controls
basic hardware functions and power supply
connections to provide electricity to the system
components
MOTHERBOARD (BASIC)
MOTHERBOARD (ADVANCED)
CPU AND MEMORY REVIEW
Hardware = Body
Software = Thoughts
CPU (Central Processing Unit) = Brain
In addition to the CPU, the motherboard contains
two kinds of memory chips: ROM (Read Only
Memory) and RAM (Random Access Memory)
ROM chips have programming permanently stored on
them however Flash ROM is rewritable.
CPU AND MEMORY
CPU AND MEMORY
RAM memory chips are installed onto the
motherboard
They hold both data and programming
instructions while they are being processed by
the CPU.
ROM chips contain permanent (longterm)memory whereas, RAM is temporary
(short-term).

On the motherboard
Peripheral Devices
PERIPHERAL DEVICES
Peripheral devices connect to and communicate
with the computer either internally or
externally. Although they can attach to it, they
are not part of the motherboard.
External peripheral devices communicate with
what is inside the computer through cables
attached to the case at a connection called a
port.
PERIPHERAL EXAMPLES
Video card - a board inside the computer that
controls the video display (monitor).
Keyboard - the primary input device of a
computer.
Mouse - a pointing device used to move the
cursor and make selections on the screen.
All non-wireless external peripheral devices
communicate with the computer through
cables attached at the ports.
VIDEO CARDS
PORTS
WALK THROUGH
Show me a peripheral device and a port on your computer.
SOFTWARE
Software is a set of instructions written by
programmers to instruct computers to perform
specific tasks.
There are two types of programs: Operating
systems (OS) and Applications (Apps).
Generally a computer has one OS and several
applications.
SOFTWARE
OPERATING SYSTEMS (OS) AND APPLICATIONS (APPS)
Stored on the hard drive, the OS supports a
computers basic functions such as scheduling
tasks, executing applications and controlling
peripherals.
Apps, also stored on the hard drive, execute user
commands. They are software programs used to
create files.
FILE NAMES
A file name has two parts:
Filename – name you give your file
Extension – appended letters the
computer uses to tell which app created
the file
EXAMPLE:
Word files use .doc or .docx.
HARDWARE
HARD DRIVE
A hard drive is a self-contained storage device with
a read - write mechanism plus one or more hard
disks, inside a sealed unit. It is the primary
computer storage device.
The hard drive is a piece of hardware that stores
the OS, Apps and files.
HARD DRIVES
External
Internal
DISCUSSION QUESTIONS
Give some examples of external peripheral
devices.
What are ports used for?
Name the two types of programs? What do
they do?
What types of information are contained on
the hard drive?
DISCUSSION QUESTIONS
Give some examples of external peripheral devices.
Mouse, Keyboard
What are ports used for?
To connect external peripherals
Name the two types of programs? What do they do?
OS – controls the basic functions of the
computer
Applications – executes user commands
What types of information are contained on the hard drive?
OS, Apps, Files (Long-term memory)
DIRECTORIES
DIRECTORIES
A directory is a table on the hard drive that
contains a list of files that are stored on
the disk.
The root directory is the first directory on
the drive.
On PC’s the root directory is C Drive “C:\” by default.
On Mac directories are shown are folders.
DIRECTORIES
There are other directories sometimes
called subdirectories or child directories.
Any directory can have files and / or other
directories listed in it.
You can organize your files by creating
different directories and folders.
