Lesson 2: Computer Overview• A computer can solve problems and run programs. • The Central Processing Unit (CPU) gives instructions to
the rest of the computer.• Memory is where information is stored.• Purpose of a computer is to access data and process
data into information.

Computer Operating System
• The operating system within the computer is used to:– Manage the hardware and software resources
of the system.– Provide stable and consistent way for the
computer to use applications and interact with other hardware.

Hardware & Software
• A computer is comprised of both hardware and software.– Hardware: electronic devices and media dealing with
storage and processing.• Input: keyboard, mouse, scanner, etc.• Output: display, printer, DVD, etc.• Storage: USB drive, CD-ROM, etc.
– Software: programs and operating systems that make the computer perform various functions.

Things that Affect Computers
• Viruses:– Programs specifically created to cause
problems within your system. • Bugs:
– Problems with the software that interfere with the proper functioning of the computer.

Lesson 3: The Internet
• The Internet is a worldwide telecommunications system.
• “A network of networks.”• The Internet began in 1969 as the U.S.
Department of Defense’s Advanced Research Project Agency (ARPA).
• Network changed from military use to scientific use.

The World Wide Web• The World Wide Web was created in 1989 by Tim
Berners-Lee.• Contains a vast collection of linked multimedia pages.• Basic components that allow computers to communicate
with each other:– Transmission Control Protocol (TCP)– Internet Protocol (IP)
• URLs (Uniform Resource Locators) are addresses for Web sites.
![Page 8: CAS 283 : Communication and Information Technology](https://reader036.vdocuments.site/reader036/viewer/2022070504/568168f3550346895ddffd12/html5/thumbnails/8.jpg)
Searching the Internet
• Three general types of sites that can be used to find information:
– Directory Sites
– Search Engines
– Specialized Search Sites
![Page 9: CAS 283 : Communication and Information Technology](https://reader036.vdocuments.site/reader036/viewer/2022070504/568168f3550346895ddffd12/html5/thumbnails/9.jpg)
Boolean Trick • Useful trick that can be used to effectively search
the Internet• Involves the combination of key words with the
operator “and.”
• Tips:– Use 6 to 8 keywords per query.– Use nouns as query keywords. Never use articles
("a," "the"), pronouns ("he," "it"), conjunctions ("and," "or") or prepositions ("to," "from") in your queries.

Lesson 9: Social Networking and Online Communities
• Two types of Computer- Mediated Communication (CMC):
– Synchronous
– Asynchronous
![Page 23: CAS 283 : Communication and Information Technology](https://reader036.vdocuments.site/reader036/viewer/2022070504/568168f3550346895ddffd12/html5/thumbnails/23.jpg)
Advantages of CMC
• Distance is not a factor affecting communication.
• Time is not a factor affecting communication.
• Multiple opinions and views can be shared.
• 24/7 availability.
![Page 24: CAS 283 : Communication and Information Technology](https://reader036.vdocuments.site/reader036/viewer/2022070504/568168f3550346895ddffd12/html5/thumbnails/24.jpg)
Disadvantages of CMC
• No moderation to the discussion.• Discussions are not topic driven.• Too much information to sort through.• No definitive end to the discussion.
![Page 25: CAS 283 : Communication and Information Technology](https://reader036.vdocuments.site/reader036/viewer/2022070504/568168f3550346895ddffd12/html5/thumbnails/25.jpg)
Tips for Effective Communication
• Keep paragraphs and messages short and to the point.
• Capitalize whole words only to highlight an important point or to distinguish a title or heading.
• *Asterisks* surrounding a word can be used to make a stronger point.
![Page 26: CAS 283 : Communication and Information Technology](https://reader036.vdocuments.site/reader036/viewer/2022070504/568168f3550346895ddffd12/html5/thumbnails/26.jpg)
Lesson 11: Microsoft PowerPoint
• PowerPoint is a presentation creation program.
• It can be used to create slides, overhead transparencies, or computer screen slide shows.
![Page 27: CAS 283 : Communication and Information Technology](https://reader036.vdocuments.site/reader036/viewer/2022070504/568168f3550346895ddffd12/html5/thumbnails/27.jpg)
Presentation Layouts

• Don’t capitalize or bold everything.• Limit text to 8-10 lines maximum per slide.• One idea per slide.• One background color scheme throughout
presentation.

Bad Design Tips
• Material too close to the edge.• Too many points on a slide. • More than 30 characters per line. • More than six words per line.
![Page 33: CAS 283 : Communication and Information Technology](https://reader036.vdocuments.site/reader036/viewer/2022070504/568168f3550346895ddffd12/html5/thumbnails/33.jpg)
THE FIVE STAGES OF GRIEF• 1) Denial and Isolation : The first reaction to learning of
terminal illness or death of a cherished loved one is to deny the reality of the situation. It is a normal reaction to rationalize overwhelming emotions. It is a defense mechanism that buffers the immediate shock. We block out the words and hide from the facts. This is a temporary response that carries us through the first wave of pain.
• 2) ANGER: As the masking effects of denial and isolation begin to wear, reality and its pain re-emerge. We are not ready. The intense emotion is deflected from our vulnerable core, redirected and expressed instead as anger. The anger may be aimed at inanimate objects, complete strangers, friends or family. Anger may be directed at our dying or deceased loved one. Rationally, we know the person is not to be blamed. Emotionally, however, we may resent the person for causing us pain or for leaving us. We feel guilty for being angry, and this makes us more angry.
