What is Networking? (Tutorial -1)

A *networking* can be anything from a collection of computers at one location that have been tied together using a particular connectivity medium(such as copper wires) to a global network, such as internet, that uses a number of different connectivity media, including satellite technology. The network is used to transmit data, voice, even video among many users on network.networks consist of the computers, wiring, and other devices, such as hubs, switches, and routers that make up the network infrastructure. Some devices such as network interface cards,serve as the computer's connection to the network.
Devices such as switches and routers provide traffic control for

the network. All sorts of different technologies can actually be employed to move data from one place to another place, including wires, radio waves, and even microwave technology.

Networking means a group of computer which can share resources. Networks can be small as two or more than two computers connected in a peer-to-peer arrangement or as large as global networks such as the internet that uses a number of different types of network such as LAN, MAN, WAN connectivity strategies, including satellite technologies.

Network Topologies (Tutorial-4)

Topology refers to the way in which the network of computers is connected. The choice of topology is dependent upon--- Type and number of equipment being used Planned applications and rate of data transfers Required response times Cost Types of Network Topologies Physical Topology: Physical topology defines how devices are connected to the network through the actual cables that transmit data(physical structure of the network) Logical Topology: Logical Topology (also referred to as Signal Topology) is a network computing term used to describe the arrangement of devices on a network and how they communicate with one another.

Cisco Hierarchical Model

Cisco Hierarchical Model Defined by Cisco to simplify the design, implementation, and maintenance of responsive, scalable, reliable, and cost-effective networks. The 3 layers are logical and not physical – there may be many devices in a single layer, or a single device may perform the functions of 2 layers, eg: core and distribution. The Cisco Hierarchical Model

Eden: PHP Library To Get Things Easy For PHP Developer

Eden is PHP Library designed for helping developers in their rapid development work. In Our most of the project we have to integrate our developed website or application with most of the social networking websites like Google, Facebook, Twitter, yahoo etc. so what we do is we integrate libraries of different websites differently Although We could make the code reusable but still if the websites increases then confusion will also increases. Adding different libraries form different sources add more complexity to your project and ends up to be hard to maintain. Eden simply a set of reusable components, that works with any PHP framework and CMS. Eden makes code logical and readable with dead simple syntax.
