YOU HAVE THREE MINUTES!

Pixie Warm-Up

We will be able to identify ◦What a peripheral is◦Examples of Input and Output Peripherals◦How peripherals communicate to the

computer◦Components of a workstation◦The pros and cons of different types of

printers◦Different types of keyboards, monitors,

and mice.

Peripherals- Objectives

Any external device that provides input and output for the computer. Not part of the essential computer.

◦For example, a keyboard and mouse are input peripherals, while a monitor and printer are output peripherals. Sometimes called "I/O devices" because they provide input and output for the computer.

What is a Peripheral?

Input- An input device is a peripheral used to transfer data from the outside world into a computer system.In other words, it is any machine that feeds data into a computer.

Output- An output device is any peripheral that is connected to a computer and used to transfer data out of the computer in the form of text, images, sounds or other media to a display screen, printer, loudspeaker, or storage device.

Input Vs. Output

Examples of Common Peripherals

Digitizes Documents

Open up your Pixie document.

Once you place a peripheral term in the correct column pass the mouse to your neighbor.

Go Over Warm- Up as a Class

• Walk around the room and identify as many peripherals as you can.

• Each group will receive a different color post it note. Place this post it on any peripheral device you see around the room.

• Each peripheral may NOT have more than one post it.

• The group with the most amount of post its receives a reward!

READY……….SET……GO!!!!

The Amazing Race for Peripherals!Plus a 2 Minute Stretch!

Educational Peripherals

When a device is connected into a computer, the computer finds the hardware/software and recognizes it as part of the computer. You are then able to access the device. It then transfers data into the computer or relays information out.

Printer Name Pros Cons

Ink Jet- spray tiny dots of ink on a surface to create an image

Inexpensive to purchase and wide acceptance of paper types

Slow when printing many documents, easily clogged nozzles which leads to wasted ink, and dependent on specific ink

Laser- use toner drums that roll through magnetized pigment and then transfer the pigment to a surface

High speed, low noise, high quality, and user friendly

Not environmentally friendly, take up a lot of workstation spaces, more expensive to purchase, and expensive to repair

Dot Matrix- (common in the 1980’s and 90’s) use a print head to embed images on a surface, using an ink ribbon

Cheap and easily accessible, printing costs are low, able to make carbon copies, they tolerate dirty and hot conditions, and maintenance cost is low

The output is not a high resolution, makes a lot of noise, and not user friendly

Pros and Cons of Printers

-HP-Lexmark-Brother-EPSON

Popular Printer Manufacturers

LCD (Liquid Crystal Display) - more expensive than CRT's- introduce the problem of viewing angles- display is far superior than the CRT monitor- compact

CRT (Cathode Ray Tube)- bigger and bulkier than an LCD. - consume more power and prone

to screen flicker

Monitor

Wired- The PS/2 and USB are the two wired connections that connect the keyboards to your desktop computers.*

Virtual- The virtual keyboards are not actually physical keyboards, but they are simulated using a software. Usually, they are used in the PDA.

Wireless- The three basic types of wireless keyboards are bluetooth, infrared, and radio frequency

Keyboard

Mechanical: The ORIGINAL mouse. Houses a hard rubber ball that rolls as the mouse is moved. Sensors inside the mouse body detect the movement and translate it into information that the computer interprets.

Optical: use lasers to track the mouse's movement in relation to the surface it passes over without the use of a ball.

Infrared (IR) or radio frequency cordless mouse: With both these types, the mouse relays a signal to a base station wired to the computer's mouse port. The cordless mouse requires power, which comes in the form of batteries.

Trackball: Essentially used as an upside-down mouse, users rotate an enlarged ball that is tracked by sensors.

Mice

1. We have broken the class into four groups.2. Each group will be assigned a question. 3. You must work with your group members to

record your answers using the flip cam. 4. Then, upload your short film to the

computer. Save it to the desktop.5. Access our Wikispace under the tab titled

Flip Cam Answers(Peripherals)6. Edit the page, click on file, and upload

video.

Please use our Wikispace as a helpful study guide for our summative assessment.
