The internet refers to the actual network of connected computing devices.
The world wide web is a collection of interlinked websites and other web resources that use the internet to share data.
The client-server model describes how the flow of data is transferred on the internet.
Web 2.0 applications provide a dynamic user experience by:
This was made possible through technical advances such as JQuery and web frameworks.
Mobile internet traffic accounts for more than half of all internet traffic and has caused web development practices to provide a good user experience regardless of device type.
Responsive web design allows the presentation of websites to adjust based on the size of the window in which they are displayed.
Mobile applications are not a part of the world wide web although most of them are connected to the internet.
Transmission Control Protocol and Internet Protocol (TCP/IP) are standards for data transfer which allow networks all over the globe to communicate with each other.
The OSI Model is a conceptual, implementation-neutral model that describes networking in seven separate layers, where each layer covers a set of functions and tasks.
This model helps us communicate while we do network troubleshooting and architecture.
The TCP/IP Model is an implementation-specific networking model that revolves around the TCP protocol and IP addressing which anchor the Internet as we know it.
Its layers include:
The OSI layers include: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Three broad categories of networks include:
The Internet is technically a WAN.
A network is two or more computers or devices that are linked in order to share information.
Networking refers to a large set of standards and protocols that organize and regulate the sharing of information.
A network protocol is a set of standards for Internet traffic.
Among them are the big transport protocols:
