Introduction IT Information Information Technology Communication and Technology (ICT) What is Information Communication and Technology? ICT deals with the use of different communication technologies such as mobile phones, telephone, Internet, etc. to locate, save, send, and edit information. Example: when we make a video call, we use internet. 2 The Current State of ICT 3 Three Generation s of Internet Web 1.0 Web 2.0 Web 3.0 4 Web 1.0 When WWW was invented, most web pages were static.(Read – only) Static (also known as flat page or stationary page) in the same that the page “as is” and cannot be manipulated by the user. This referred to as Web 1.0. Example of a static website from the web 1.0 generation is the website for the 1996 movie space jam. 5 Web 2.0 This is accomplished by giving the users the power to share different types of information such as : 1.Text 2.Images 3.Sounds 4.Videos Online Banking Online Shopping Media Sharing 7 Dynamic Website Dynamic website can change their appearance and behavior based on the users action. Google search is a dynamic website, which means that its URL changes depending on the users location, credentials and search parameters. It also recognizes different forms of user input like keywords, voice command, and image upload. 8  Operating System. 9  FR Operating System. 11  WEB 2.0 WIKI Derived from the Hawaiian word wikiwiki, which means “quick” or “super fast”, a wiki is a website that allows visitors to add or edit its contents. Each wiki page is about a single topic that is presented in a manner similar to an encyclopedia or an educational article. 12  Operating System. 13  WEB 3.0 Web 3.0 the current generation of the Internet Web 3.0’s main characteristics include, but are not limited to: 1. Real-time Events and information are made available to users as they happen. 2. Ubiquitous Users are always connected to the Internet. 3. Machine learning Computers and mobile devices can create data and make decisions based on the user’s previous actions. 14  WEB 3.0 Web Application Web applications are internet-based programs that are accessed through web browsers. Web Apps vs Native Apps Here are some examples of popular native apps and their web app counterparts: 15  W E B Cloud Computing Cloud computing is the name given to Internet- based networks that are used to store, manage, and share resources and information. 16  Operating System Server, client, and service A server is a computer that does tasks for other computers. A task that is done by a server is called a service. The computer that accesses the services that are provided by a server is called a client. The cloud First of all, “the cloud” is not an actual cloud. The cloud is a network of servers that provide different services. For example, one server may be tasked to collect information from other servers that are tasked to store them. All these servers work together to provide one unified service to the client. 17 Benefits of Cloud Computing ICT 1. Reduced Cost Subscribing to cloud-based services is a lot cheaper than traditional options such as building your own programs, buying your own hardware, and hiring more people. 18 2. Flexibility Operating System. Cloud-based services can be upgraded or downgraded to suit the clients’ need. Subscribers can upgrade their subscriptions to gain access to bigger data storage, more powerful tools, and exclusive features. On the other hand, subscribers on a tight budget can downgrade their subscriptions to reduce their expenses but still get the necessary services. 19  Operating System. 3. Mobility Because cloud-based services rely on the Internet, clients can access them using computers and mobile devices in different locations. For example, an employee can save his work in the cloud and access it at home or on vacation. 20  Operating System. 4. Better Collaboration The cloud enables people in different location to work on the same project. A multi-national team can communicate and share information and resources with one another using cloud based services. 21  Operating System. 5. Updated Software Providers of cloud-based services compete with each other in delivering the best services to clients. Because of this, cloud-based apps are constantly improved and these improvements are immediately made available to the clients. 22 20
