A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork until it reaches its destination node.
A network switch is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device.

Network security consists of the policies and practices adopted to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, which is controlled by the network administrator. Users choose or are assigned an ID and password or other authenticating information that allows them access to information and programs within their authority. Network security covers a variety of computer networks, both public and private, that are used in everyday jobs: conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access. Network security is involved in organizations, enterprises, and other types of institutions. It does as its title explains: it secures the network, as well as protecting and overseeing operations being done. The most common and simple way of protecting a network resource is by assigning it a unique name and a corresponding password.

Etch was an open-source, cross-platform framework for building network services, first announced in May 2008 by Cisco Systems. Etch encompasses a service description language, a compiler, and a number of language bindings. It is intended to supplement SOAP and CORBA as methods of communicating between networked pieces of software, especially where there is an emphasis on portability, transport independence, small size, and high performance. Etch was designed to be incorporated into existing applications and systems, enabling a transition to a service-oriented architecture. It was derived from work on the Cisco Unified Application Environment, the product acquired by Cisco as part of the Metreos acquisition.
