Instructional Technology

 

Definition

Instructional technology is just what it sounds like: using computers, CD-ROMs, interactive media, modems, satellites, teleconferencing, and other technological means to support learning.

Discussion

Some educators believe the use of interactive, computer-based technology is crucial to improving classroom learning. These educators contend that advanced technology will fundamentally change the learning process and structure. Other educators believe technology is merely a tool that has minimal impact on the quality of learning.

How Instructional Technology Affects Learning

Curriculum–Advanced technology has the potential to significantly expand the breadth and depth of the curriculum. With the Internet, for example, students can access information far beyond the scope of their traditional textbooks. Curricula can be individualized and adapted to students’ specific learning styles. Instructional technology has the power to enhance overall knowledge accumulation, instead of just focusing on content mastery.

Instruction–Advanced technology could significantly affect the role of teachers, as well as the structure of schools and classrooms. The use of instructional technology changes the teacher’s role from expert to facilitator or coach. Plus, instruction is no longer limited to the school building or classroom. For example, students can take courses from a global satellite feed or on the Internet. Learning can take place at home, at work, or anywhere else that has the capacity for a television, phone, or computer.

Assessment–Instructional technology will focus more and more on building feedback loops directly into the learning process. Students can obtain frequent and accurate feedback, make corrections to their work, and structure learning experiences around their individual needs. Assessment can be monitored by offsite instructors, plus it can be ongoing and cumulative.

 

The Parts of Computer

 

 

1- Disk-a disk is a piece of plastic that holds information for or from your computer

 

 

 

 

 

 

 

 

2- C.D.-a round circle holds information for or from your computer.

 

 

 

3-Hard Drive-hard drives are machines that have alot of memory to save your work and carries a c.d.rom and a floppy disk

 

 

 

 

4-Keyboard-a keyboard is a tool that is used for typing like a typewriter.

 

 

5-Monitors- a monitor is the screen on your computer that you look at when you are on the computer.

 

 

6-Mouse- A piece of plastic that has a ball on the bottom and two buttons on the top. When you click on the mouse, you usually click on the left button. It allows you to click on and choose things on your screen.

7-Printer- A machine that puts things from the computer onto paper.

 

 

 

 

 

 

8- Scanner- A piece of equipment that copies pictures so that you can use it in your computer projects.

 

9- Speakers- The part of the computer that lets you hear the sounds from the programs.

 

10-Modem- A part of the computer that connects to the phone lines so that you can go on the Internet.

Virus

Some people believe that there is no longer any interesting research to do in the field of protection from computer viruses - that all of the important technology has already been developed - that it is now a simple matter of programming to keep up with the problem. Others believe that "virus research" simply means "analyzing viruses." To dispel these misimpressions, we discuss several important research problems in the area, reviewing what is known on each problem and what remains open.

The problems we have selected have two characteristics. The first is that, if the problem were solved, it would significantly improve our ability to deal with the virus problem as it is likely to evolve in the near future. The second is that the problem constitutes an actual research problem, so that a definitive solution would be publishable in peer-reviewed computer science journals,

I  discuss five problems:

As more viruses are written for new platforms, new heuristic detection techniques must be developed and deployed. But we often have no way of knowing, in advance, the extent to which these techniques will have problems with false positives and false negatives. That is, we don't know how well they will work or how many problems they will cause. We show that analytic techniques can be developed which estimate these characteristics and suggest how these might be developed for several classes of heuristics.

1. We have a reasonable, qualitative understanding of the epidemiology of computer viruses, characterizing their spread in terms of birth rate, death rate, and the patterns of program transfer between computers. But a mystery remains. Evidence suggests that viruses are still relatively uncommon - that their prevalence has always been very low. But, according to our current theories, this can only happen if the birth rate of viruses is ever so slightly higher than their death rate, a coincidence too remarkable to believe. We discuss effects that might be responsible for this puzzling observation.
2. We are in the process of deploying digital immune system technology that finds new viruses, transmits them to an analysis center, analyzes them, and distributes cures worldwide, automatically, and very quickly. The current architecture for this system uses a centralized analysis center for a variety of good reasons. But a more distributed approach, perhaps even a massively distributed approach, has advantages as well. We outline the system issues that must be considered, and what simulation results would be useful, in understanding the tradeoffs.
3. There have been thankfully few instances of worms - freestanding virus-like programs that spread themselves and may never be present in the computer's file system at all. Yet virtually all of our anti-virus technology relies on detecting and removing viruses from a file system. We discuss the new problems that worms engender, and suggest some of the new technology that may be needed to deal with them.
4. Current anti-virus technology is largely reactive, relying on finding a particular virus before being able to deal with it well. Modern programming environments can give rise to viruses that spread increasingly rapidly, and for which a reactive approach becomes ever more difficult. We review the history of pro-active approaches, showing why traditional access controls are basically useless here, and describe newer approaches that show promise.

 

Hi my friends     

importance of technology in our life

 

 Why is Technology Important ?

Places far away have come closer, thanks to technology. The pace of life has increased, thanks to technology. Communication is quick, travel is fast, movement is easy, action is quick, interaction has sped up and so has life. Things that once took hours to complete, can be done in seconds. The world is smaller and life is fast. Courtesy - technology.

The discovery of electricity drove all the darkness away and the world lit up. If not for the use of technology, we wouldn't have been able to produce electric power or harness it. Today, it can be generated through various means because of technology. It has been channeled to every small household in the farthest of world's corners, thanks to technology. What made it possible to use renewable sources like hydropower or solar and wind energy to generate electricity? Application of technology.

How would our basic needs be met so easily if not for technology? Man could meet his needs even before the birth of technology. But it was so difficult then and so rudimentary. Look at today's food - fresh, preserved or processed, food of any type is available at your doorstep just anytime. Clothing? Gosh, there's so much variety and much more comfort with different clothes for different occasions and seasons. Where does technology come into picture? Everywhere. From food to fashion, technology has a role to play. How else would so much of all this be produced? Look at today's shelters - shelters? Tall buildings, big bungalows, luxurious apartments - how would they be built if not for technology!

What is information technology

Set of tools, processes, and methodologies (such as coding/programming, data communications, data conversion, storage and retrieval, systems analysis and design, systems control) and associated equipment employed to collect, process, and present information. In broad terms, IT also includes office automation, multimedia, and telecommunications

Technology has changed the way people communicate. Communication systems have evolved from pigeons carrying messages to emails and instant messages that travel long distances in seconds. Cellular technology and satellite communication have increased communication speeds and made 'connecting' easier. The Internet has enabled easy exchange of information over long distances. Even now, you could be accessing this page from a web server in some far-off country. Just a few clicks of your computer mouse can take you anywhere on the Internet. You enter an all new world without even realizing it!
