Discuss Blown to Bits questions - pair share

What?

Quick Write - Create a new google document called Quick Write and then copy the following question with today's date. Which of the following would be the greatest disaster, the crash of a supercomputer or of a mainframe. Justify your answer.
This is not a formal writeup but a quick thesis statement followed by bullet points to support your answer.

Do you think there were any companies in Houston who lost their mainframe because of flooding? What could have been done to prevent such a loss?

Q. The terms Internet and WWW are often used interchangeable. Are these the same thing? Explain. Evaluate the following answers.

4. At first the internet was mostly used by researchers and computer scientists who knew all the commands and codes necessary to utilize the internet. In the 1990’s the World Wide Web was created and granted internet access to average citizens through electronic mail and new easy to use visually interfaced web browsers.

4. No, the internet is the directly connected network of computers which comprises mainly of universities and government agencies which was not very user friendly, while the World Wide Web was a complete overhaul of the web protocol which made it much easier for a normal person without much computer knowledge to access the internet.

Q. What is the difference between a desktop computer and thin client?

5. A thin client is a computer that gets all it computing power and storage from the internet. It does not function without a connection to the internet and has no moving parts because it has no memory or CPU. Because there is less hardware in thin clients, they are usually cheaper than PC’s. It would be lower in the computer hierarchy because it is made primarily for communication and not intensive computing.

Study Guide for Chapter 1

Introduction to Chapter 2 - Hardware Basics - your instructor will identify the basic computer components. You will then use this information to identify these same components on your computer.
Inside the Black Box Lab

Computing Prefixes - kilo, mega, giga, tera, peta, exa, zetta, yotta

What comes after a yottabyte?

From Startup to Shutdown - what devices are activated and in what order? How is information transferred?

From Startup to Shutdown - POST Lab - work with a partner for this lab. One person takes notes while the other person follows the steps. The person taking the notes should share the document with their partner.

Begin Chapter 2 Hardware Questions Green Book. Upload to School Loop
Read pages 30- 35 (green book) to answer the following questions.

  1. What is speed throttling and why would it be used?
  2. Is a single core CPU capable of true multi-tasking? Explain.
  3. Differentiate between RAM and ROM giving examples of each.
  4. A video production student needs to be able to edit the same files in class and at home. Raw video clips can easily take up to 2 GBs and editing usually involves the use of many video clips. What would be your recommendation for this student for easily transporting the files between school and home? Provide two recommendations.
 

Homework

Search for a news article directly related to a new development in hardware - due Friday. Add to your excel spreadsheet and upload to school loop. Focus - discuss the significance of this new development. Can be computer, mobile device, accessory hardware.
Yasmine and Brandon will present this Friday. Your presentation must be made using Prezi

Read pages 81-91 in the blue book

Complete Chapter 2 Hardware Questions Green Book if you did not finish this in class. Upload to School Loop.

Study Guide for Chapter 1 - complete the study guide and once your score is 100% email the results to cdodge@seq.org and also email yourself a copy as well.

Review the internal parts of a computer, the quiz for this will be Friday.

Add the following terms to your definitions spreadsheet — data, information, hardware components, for example, input devices, output devices, processing, storage, memory (RAM, ROM), MHz, dpi, bit, KB, MB, GB, TB, ASCII, compatibility, OCR, OMR, bar code, verification and validation, encryption/decryption, peripheral, operating systems (multitasking, boot) and utilities, for example, fragment, disk format, virus scan programs

Definitions are due when the chapter is finished.
 

What

3.1 Hardware page 26
Central processing unit (CPU), microprocessor, clock speed: for example, megahertz (MHz), gigahertz
(GHz), terahertz (THz)
• Primary storage: read-only memory (ROM), random-access memory (RAM)
• Secondary storage: optical, magnetic, flash memory: for example, USB (universal serial bus) flash drive
• Bit, byte, kilobyte (KB), megabyte (MB), gigabyte (GB), terabyte (TB), petabyte (PB), exabyte (EB),
zettabyte (ZB), yottabyte (YB)
• Character encoding: ASCII (Unicode and American Standard Code for Information Interchange)
 

Why

Understanding how information flows in a computer system allows one to make connections with larger systems and the flow of information.
 

How

Completion of the Black Box lab and the corresponding quiz to identify the components of a computer.
