This document provides an overview of basic computer hardware components and how they work together. It discusses input devices like keyboards and mice that allow data to enter the computer. It describes the central processing unit (CPU) as the computer's brain. It explains that storage devices like hard drives are used to save files and data. It also covers output devices such as monitors, printers, and speakers that allow users to see and interact with processed data. The document aims to give the reader a basic understanding of where computer parts are located and how they function within the system.

1. Understanding how data
is presented to the
computer is essential in
getting a feel for the flow
Review input, output and
storage facilities in your
computer
Having an idea of
where the parts are
and how they work
helps the learning
process

3. Bytes and Bits
Binary code is the language that computers speak. It is the basis for all
computations. Binary consists of 2 states: on and off = 0 and 1(And that’s about all
I know)
Bits are the smallest unit of data that a computer can comprehend, represented by
0’s and 1”s
Eight bits make up one byte
A file represents a collection of bytes that are responsible for any type of data

4. The CPU
Your guess is
as good as
mine, let’s
see what we
can come up
with
together.

5. Input Devices
Input devices are
any pieces of
equipment that
would be used to
input data into
the computer
Some of the common devices we're
all familiar with such as keyboards,
pointing and touch devices such as
the mouse. Scanners and readers
may be included.
More and more often things such as images,
videos, and various audio input are becoming
more common place.

6. The Unit Itself
 The package, so to speak, is what they call the housing unit. It
is that unit that houses all of the hardware. For a desktop PC
you may call it a tower.
 Some things you will find it include the power supply, memory,
expansion slots and cards, power supply sources, expansion
slots, cards, buses, ports and connectors.
 A popular term you may hear is plug-and-play. This means that
your computer will automatically configure new devices upon
installation and reboot.

7. Your Systems Storage
The storage system allows
for the possibility to save
multiple programs data and
processing results for use at
a later date
I'll storage systems
contain hardware in
which data is stored.
These storage units are
referred to as mediums
Hard drives, smart cards, optical disks,
storage servers, flash memory, remote
storage (including online and clouds)
just to name a few are examples of
storage devices

8. Output Devices
An output device gives the user the
ability to see and interpret data that has
been processed
Some common output devices
may be your screens, any type of
projectors, printers and even
audio speakers. Can we think of
anymore?
