my new presentation about computing

1. María Donoso Íñiguez 3ºA

2. WHAT IS HARDWARE
Hardware is the physical part of a
computer, it is composed of electric,
electronic and mechanic components.

3. WHERE IS FOUND
HARDWARE
WHERE IS FOUND
HARDWARE
Hardware is found in computers,
mobile phones, cameras,
robots.etc.

4. PARTS OF HARDWARE
CPU
RAM
Optical Disc
Motherboard
Monitor
Mouse
Keyboard
Hard Disk Drive
Power Supply
Expansion
Cards

5. MOTHERBOARD
Motherboard is the body of the computer, in
which all the components are found.
Motherboard provides the electrical connections
by which the other components communicate.

6. CPU
CPU (Central Processing Unit) is like the brain of
the computer. It is a machine that executes
computer programs.

7. RAM
RAM (Random Access Memory) is used to store
programs that are currently running. It is called
Random because is a set of circuits that allow the
stored data to be accessed in any order.

8. EXPANSION CARDS
An expansion card is an electronic card added
into a desktop computer. These cards give that
computer a new ability, like the ability to connect
to another computer using a network cable.

9. POWER SUPPLY
The power supply, also known as PSU (Power
Supply Unit) is used to convert the power
provided from the outlet into usable power for
the components of the computer case.

10. HARD DISK DRIVE
A hard disk drive (HDD) is the mechanism that
controls the positioning, reading, and writing of
the hard disk, which provides the largest amount
of data storage for the PC.

11. WHAT IS SOFTWARE
Software is a collection of instructions
that enable the user to interact with a
computer. Without software, computers
would be useless. For example, without
software you wouldn't surf the Internet.

12. WHERE IS FOUND
SOFTWARE
● Software in the network:
Programmes and applications on the Internet.
The advantage is that it is not necessary to install
or configure them. For example: Dropbox.
● Local software:
In this case, programmes need to be installed and
stored in the computer. For example: Windows.

13. Software quality is very important, especially
for commercial software, like Microsoft
Office, Microsoft Windows and Linux.
QUALITY

14. EXECUTION
Software has to be “loaded” into the
computer's storage. After that, the computer
is able to execute the software. This involves
passing instructions from the application
software.

15. WHAT ISDEP
DEP (Data Execution Prevention) is a security
feature that prevent damage to your computer
from viruses. DEP can protect your computer by
monitoring programs to make sure they use
system memory safely.
