ITGS Post #4: Reliability and Integrity

Reliability:

• Operation of Hardware
• Design of Software
• Accuracy of data
• Corresponsence of Data with the real world
• Data may be unreliable if entered incorrectly or if it becomes outdated

EX: Medical reord that dissociates from the patient it refers to becomes unreliable.

Reliable Hardware:

• Perform Accordingly
• How we judge, measures reliability
• reaction time
• cable varies
• pay for specific bandwidth

Software:

• Perform up to expectations
• degredates
• Outdated

EX: Mocrosoft updates because it is exploiting the vulnerability of the software. This means that it is vulnerable for attacks from outside

Bug: virus or defect
Data: it can be unreliable sometimes. Human Error on Air Shuttle accident

Integrity:

• correspondence of data with itself at its creation
• lacks untegrity when it has been changed accidently or tampered with.

EX: Hacker might change driver's license data which leads to arrest of innocent people

Use of this in Teaching and Learning:

• Education Software
• Online Reserach and forums
• virtual learning envireonments
• e-books
• Web 2.0
•  Education Networks
• Use of mobile devices
• Game based Learning
• Fully Immersive Envireonments
• Filtering the moniter of students internet use

Hardware and Network Technologies in the Classroom

• laptops
• handheld devices
• interactive whiteboards

Old School vs. New School

• Teachers feel that in this day and age, they need to "entertain" students to keep their attention
• Claim that without use of digital media, students see the classroom as a desert
• Feel that they must ACCEPT REALITY
• Other teachers say that technolgy leads to the inability of the students to focus
• The Quickness of things is too much
• Belive that students are taking over

Social and Ethical Issues:

• So much technology leads to the loss of skills and decrease in education
• Students are "paralyzed"
• No books equals the demise of society
• Losing touch of History
• No connection
• Loss of Respect
• Frequency is at a disconnect
• Lessens critical thinking
• dependent
• disconnect with family
• loss of communication skills

The Keyboard:

• Repetitiv-Stress Injuries: long hours of typing at unnatural angles leads to medical problems
• Ergonomic Keyboards: place the keys ar angles that are easier on your arms and hands without changing the ordering of the keys.
