Web 2.0

What is Web 2.0?

Web 2.0 describes World Wide Web sites that use technology beyond the static pages of earlier Web sites. A Web 2.0 site may allow users to interact and collaborate with each other in a social media dialogue

Examples of Web 2.0 include: social networking sites, blogs, wikis, folksonomies, video sharing sites, hosted services, Web applications, and mashups.

Web 2.0 in education:

Web 2.0 is used now in educational field as Web 2.0 technologies can provide students with more engagement through greater customization and choice of topics, and less distraction from their peers. By allowing students to use the technology tools of Web 2.0, teachers are giving students the opportunity to share what they learn with peers. Web 2.0 calls for major shifts in the way education is provided for students as it makes education collaboratively constructed. These tools can be used in :-

1-   Tools that create or support a virtual learning environment. ( blogs and wikis)

2-  Tools that support communication and cultivate relationships.( social networks)

 3-  Resources to support teaching and learning.( online teaching websites and games- teach-ict.com)

4-   Tools enabling students to create artifacts representing what they are learning.(programs and websites that help in making presentations like prezi and

       e-maze)

Online Systems ... A glimpse of the future!

E Banking

Online banking is an electronic payment system that enables customers of a financial institution to conduct financial transactions on a website operated by the institution, such as a retail bank, virtual bank, credit union or building society. Online banking is also referred as Internet banking, e-banking, virtual banking and by other terms.

What is meant by online transaction?

Online transaction processing, or OLTP, is a class of information systems that facilitate and manage transaction-oriented applications, typically for data entry and retrieval transaction processing.

What is meant by E-shopping?

Online shopping or e-shopping is a form of electronic commerce which allows consumers to directly buy goods or services from a seller over the Internet using a web browser.

What are online auctions?

Online auctions are places that people can go in order to buy or sell goods or services online for a small fee. Anyone can sell an item and anyone can bid on an item.

Advantages:

1) Merchandise has exposure to the traffic of the online auction site.

2) If an item is popular, bidders can push the price up beyond its starting price.

3) You can add multiple photos with different views.

4) You can add detailed decriptions and shipping information.

5) Some sites offer promotions with no listing fees or other specials for a

limited time.

Disadvantages:

1) The item may not sell, you'll have to re-list it, and pay an additional fee.

2) A buyer may bid and not pay, resulting in a lost sale and a re-listing fee.

3) It is time-consuming to add a category, descriptions, price, shipping

method, and photos to a listing.

4) It is time-consuming to promote listings to drive traffic to auctions.

5) People may try to convince you to close a listing and sell to them off the site.

CAD & CAM ...It's the world of DEVELOPMENT!

Some applications used by CAD and CAM :

1-  AutoCAD software : 
it was made in 1982 it enable extended teams to explore their projects’ key physical and functional characteristics digitally, before the projects are built.

2- Maya 3D animation software and 3ds Max modeling and animation software: 
 enable you to create sophisticated effects, design innovative experiences, and improve production efficiency when creating compelling visual effects for films, games, or television shows.

3- HSMWorks and HSMXpress : 
easy-to-use full featured CAM solution that allows all licensed users of SolidWorks 2010 or newer to create high quality toolpaths using the latest in 64-bit and multi-core technology.

The Advantages of using CAD and CAM systems:

1-Can be more accurate & it reduces human error.

2- You can save and edit ideas, which makes it easier and cheaper to modify your design as you go along.

The Disadvantages of using CAD and CAM systems:

1- The software itself can be expensive so initial costs are high.

2- Staff need to be trained how to use the software, which also adds to costs.

3- suitable PC must be provided to use these systems 

With Softwares...Profit Making is an Easy task!

Anyone who says their business "runs itself" probably owes a great debt of gratitude to a small army of software applications and Web services that tirelessly feeds the machine from behind the scenes.many softwares are used by businesses whether big or small to make their work more easy and accurate such as  :

1- Intuit QuickBooks Pro:

The flowchart-based accounting of QuickBooks is as close to a standard in financial management as the small-business world has,the easiest way for nonprofessionals to transfer their books from the filing cabinet to the computer, where they belong. Most actions, from cutting a check to billing a client, are just a click or two away from the start screen.

2- FileMaker Pro : (Database software)

Access is a part of many editions of Microsoft Office, but if you don't already have that database program in your toolkit, consider springing for FileMaker Pro instead. This database application is more intuitive than Access, every data needed then can be processed and checked in a very brief time whether employee,customers, or suppliers data.

3-Office Suite:

Like it or not, any business, big or small, probably needs at least one copy of Microsoft Office somewhere in the building, every software in the suite can be helping the business to a huge extent like writing letters , keeping track of the company's stock and sales, calculating profit and loss...ect

 

The impact of modern communication application on society

In the 1840s and the late 1870s the development of the telegraph and telephone made rapid long-distance communications possible. Both media began in local areas and then rapidly spread around nations accelerating the pace of social interaction, migration, commerce, and government activities.

 But the innovation in electronic communications continued to progress during the 1940s. The need to deliver signals to communities in remote mountain areas led to the early development of communication systems, which with the adoption of coaxial cable, and more recently fiber optic cable helped companies to deliver video, voice, and data services to customers, in a very accurate way on TVs and phones. So now it is very easy to send and receive signals and to communicate with whole world easily.
 

3D Blu-Ray Player

Blu-ray (not Blue-ray) also known as Blu-ray Disc (BD), is the name of a new optical disc format jointly developed by the Blu-ray Disc Association (BDA), a group of the world's leading consumer electronics, personal computer and media manufacturers, While current optical disc technologies such as DVD, DVD±R, DVD±RW, and DVD-RAM rely on a red laser to read and write data, the new format uses a blue-violet laser instead, hence the name Blu-ray.

Technically, 3D which is a new feature can be implemented in Blu-ray in two ways:

1. A type of Blu-ray Disc player that is designed from the ground-up to comply fully with the recently adopted 3D for Blu-ray Disc standard. This means that the Blu-ray Disc player must be able to deliver two simultaneous 1080p signals (one 1080p signal for each eye). In order to do this, the Blu-ray Disc play must EMPLOY a new version of HDMI 1.4 that is able to transfer this signal. Of course, it is required that the TV must be able to receive and process this signal.

2. Based on information that may be subject to change as more details come to light, the second way to implement 3D for Blu-ray may be a "short-cut" method that would allow for a downloadable firmware upgrade for some currently Profile 2.0 (BD-Live) compatible players that would make them 3D-enabled.

However, this type of upgrade is at the discretion of the player manufacturer, and as it stands now, no manufacturers have implemented this upgrade except for Sony with its PS3 was the only confirmed upgrade to Blu-ray 3D.

  Specifications of different 3D Blu-ray players:

• Get a sharp, detailed picture.

• Smooth online streaming with a strong Wi-Fi connection.

• Share with screen mirroring (with compatible smartphones).

• Efficient performance with a dual core processor.

• See a new dimension with Full HD 3D.

• Super quick start.

• Plug-in to play movies via USB.

• 3D capability.

 ((Advantage))

1- 3D Blu-ray Disc movie can be played on any 3D-enabled Blu-ray Disc player regardless of brand or model. 

2- The 3D features can be implemented to the Blu-ray player so no need to spend money on buying a new player.

((Disadvantage))

1- must have a 3D screen to view the images

2- the resulting resolution will not be in high 

definition

The introduction of the 3D facility to the Blu-ray players provided them with new characteristics that are attractive to many users and so it made a major step in the Blu-ray manufacturing organisations .
