4. What is a Computer?
Click to play video
A computer is an electronic device that manipulates information, or data.
It can store, retrieve, process data, and produce a result.

5. Types of Computers
Desktop computer—usually sits on a desk. They are easy to upgrade and expand or add new parts.
Laptop computer—often called a notebook computer because of its size, is more portable than desktops.
Inform students that desktop and laptop computers are personal computers.

6. Types of Computers
Tablet computer: uses touch-sensitive screen for typing and navigation.
Ex) iPad
Inform students that desktop and laptop computers are personal computers.

7. Types of Computers
Server—the main computer on a network that provides services to other computers on a network. A server can be as small as a desktop computer or be large enough to take up an entire room! We’ll learn more about networks later…

8. Personal Computers
Personal computers, such as desktop and laptop computers, come in two main styles:
PC:
Introduced by IBM in 1981.
Most common personal computer.
Typically includes the Microsoft Windows operating system.
MAC:
Introduced in 1984 by Macintosh.
First widely sold personal computer with Graphical User Interface (GUI)
All made by Apple Inc.
Almost always use the Mac OS X operating system.
Explain and provide examples of GUI.
Explain: Although PC can refer to an IBM PC Compatible, the term can also be used to refer to any personal computer, including Macs.

9. Specialized computers
Source:
Mobile phones: can do such things as browse the Internet and playing games. Often called smartphones.

10. Specialized computers
Game consoles: used for playing video games Some game consoles, such as the Microsoft X Box, allow you to watch television and movies, connect to social media, and many other Internet-based activities!
Televisions: many TVs, called Smart TVs, have preinstalled applications that allow you to view photos and videos saved on other devices and access online content.

Hardware
Hardware refers to all the physical components of a computer. It includes all devices:
Input
output
Processing
Storage

13. Input Devices
Input devices are used to get information into a computer. How the user communicates with the computer.
Examples:
Keyboard
Mouse
Microphone
Other examples of input devices: trackball, digital pen, whiteboard
What are the following input devices?
webcam
Barcode reader
Game controller/joystick
scanner
Touch screen

14. Output Devices
Output devices are used to get information from the computer. How the computer communicates with the user.
Examples:
Monitor
Printer
speakers
Other examples of output devices: projector, headphones
What are the following output devices?
projector
headphones

15. Processing Devices
Processing devices work on the input data and generate the desired output.
The most important processing device is the Central processing Unit (CPU).
The CPU is the “brain” of the computer.
Processor speed is measured in megahertz (MHz), millions of instructions per second, and gigahertz (GHz), billions of instructions per second.
Ex) Intel, AMD

16. Motherboard
The motherboard is a large circuit board that connects input, output, and processing devices through pathways that allow data to pass through these various components.
It also contains chips that determine how, when, and where data can flow through the computer.

17. Storage Devices

Storage devices allow you to store (save) data for later use.
Internal storage devices allow data to be stored inside the computer.
Hard drive (200GB to 1TB)
Allows for fastest access to data
Two types of memory
Random Access Memory (RAM) is temporary storage; information is lost when the computer is turned off.
Read Only Memory (ROM) is long term storage.
Storage website:
Video:

18. Storage Devices
External storage devices allow data to be stored outside the computer.
External hard disk (1TB or more)
Memory card (1GB to 32 GB)
ex) SD card
External drives can be large and cumbersome, but, there are also portable external drives as well.

19. Storage Devices Compact Disk (CD) (up to 700 MB)
Compact disk-Read Only Memory (CD-ROM) is unchangeable.
Compact disk-Recordable (CD-R) can add information on multiple sessions, but can not change the information added.
Compact Disk Compact disk-Read and Write (CD-RW) can be changed.
Digital Video Disk (DVD) (up to 4.7GB)
USB/Flash drive (512 MB to 32 GB)

20. Storage Devices Storage Capacity
terabyte
Storage Capacity
1 Bit = smallest unit, either a “1” or a “0”
8 bits = 1 Byte (B)
1024 bytes = 1 Kilobyte (KB)
1024 kilobytes = 1 Megabyte (MB)
1024 megabytes = 1 Gigabyte (GB)
1024 gigabytes = 1 Terabyte (TB)

What is The Cloud?
Click here to play video
The cloud is all of the things you can access over the Internet.
When something is “in the cloud” it means it is stored on servers on the Internet instead of on your computer.
If you have web-based , all of the s in your inbox are stored on servers.
Video Link:
 Here are just a few examples of services that use the cloud in different ways:
Dropbox is a cloud storage service that lets you easily store and share files with other people, and it lets you access your files from a mobile device as well.
Evernote lets you type notes, clip webpages, take photos, and organize all of them from your computer or mobile device.
Mozy and Carbonite can automatically back up your data in case your computer is lost, stolen, or damaged.

22. What is The Cloud? Benefits of using the cloud: Risks:
Convenience and reliability. How?
Web applications (or web apps, cloud apps), which run in the cloud and do not need to be installed on your computer.
Better collaboration. How?
Less likely to lose your data since it is stored on servers.
Risks:
Someone may try to gain access to your personal data.
You can access stored information from any computer with Internet connectivity.
More easy to share files making it possible to collaborate over the Web.
