Intro to Programming

Take a look at your previous post.  We are continuing the Computer Buying Project.

Follow the rubric when creating your final project.

Presentations will be Friday!!

Moving on .......

We have explored hardware and are now moving onto data.

Programming is creating a set of instructions that tell the hardware what to do.  We are usually writing programs that collect or manipulate data to produce usable information.

For next class:

What do you think about when you hear the word data?  Where can it be found?  Where does it come from?

Intro

Week ending 31 Jan 2014

Last class we began to explore the terms computers and computing.  We classified computers into categories.

Review Question:
    What four processes do all computers perform?

Based on what we have learned about computers so far, interview a staff member to find out what features that person would like to have if they were buying a computer.

• What will be the uses of the computer?
• What are the space constraints?
• What is the price range?
• Are there any special features they would like?
• What types of software will they run?

The interview answers will be used to spec out a new system after we learn about hardware components.

You will receive a hard copy (printed paper) of the Computer Buying Project, Computer Components Checklist and the rubric.

Project will be due 31 Jan 2014.

Coursera Class

Coursera.org is offering a class called Crafting an Effective Writer:  Tools of the Trade

The session starts 2/7/2014.  If you take this course, I will give you credit under the 'Self Motivated Learner' Standard.  Grades will be based on the end of chapter quizzes and the final test.

You may feel that writing should not be part of computer class, but effective writing is a critical skill in any career.

iTunes University - Wired Study Tips

Create an iTunes University login.  We will be to watch short clips on study habits.

Review:  Can you name the components of a frame?

3.2.1  

• It takes a group of inter-related protocols to perform a communication function.  Known as a Protocol Suite
• Think of it as a layered stack.  Higher levels are concerned with the content of the data and depend on the functionality of the lower levels. The lower levels are concerned with moving data across the network and providing service to the higher levels.

3.2.1.2

• Networking protocols describe:
• How a message is formatted or structured
• The process by which networking devices share information
• How and when error and system messages are passed between devices
• The setup and termination of data transfer sessions

32.2.3

•     Shows an example of how protocols work together to provide a webpage from a server to a client.

23 January 2014 - Intro

Why do we need to learn about hardware in a programming class?

           Without software, hardware is useless.  Software provides the instructions to hardware

Add a comment:

           How many computers are in this room?  What type of software are they running?

    .1.1 What 3 elements do all communications methods have in common.

    .1.2  What are protocols?
 
        What details of communication do common computer protocols include?

    .1.3 Bits are encoded into patterns of sounds, light waves or electrical impulses.
