A switch is a device used on a computer network to physically connect devices together. Multiple cables can be connected to a switch to enable networked devices to communicate with each other. Switches manage the flow of data across a network by only transmitting a received message to the device for which the message was intended. Each networked device connected to a switch can be identified using a MAC address, allowing the switch to regulate the flow of traffic. This maximises security and efficiency of the network. Because of these features, a switch is often considered more “intelligent” than a network hub. Hubs neither provide security, or identification of connected devices. This means that messages have to be transmitted out of every port of the hub, greatly degrading the efficiency of the network.

Routing is the process of selecting best paths in a network. In packet switching networks, routing directs packet forwarding (the transit of logically addressed network packets from their source toward their ultimate destination) through intermediate nodes. Intermediate nodes are typically network hardware devices such as routers, bridges, gateways, firewalls, or switches.
The routing process usually directs forwarding on the basis of routing tables which maintain a record of the routes to various network destinations. Thus, constructing routing tables, which are held in the router’s memory, is very important for efficient routing. Most routing algorithms use only one network path at a time.
Switches create a network. Routers connect networks. A router links computers to the Internet, so users can share the connection. A router acts as a dispatcher, choosing the best path for information to travel so it’s received quickly.
Switches and routers are the building blocks for all business communications, from data to voice and video to wireless access. They can improve profitability by enabling your company to increase productivity, trim business expenses, and improve security and customer service.
- VOIP-Voice over IP:
VoIP and IP telephony are becoming increasingly popular with large corporations and consumers alike. For many people, Internet Protocol (IP) is more than just a way to transport data, it’s also a tool that simplifies and streamlines a wide range of business applications. Telephony is the most obvious example. VoIP or voice over IP is also the foundation for more advanced unified communications applications including Web and video conferencing that can transform the way you do business.
2. Video Conference/Tele presence:
Video conferencing has evolved dramatically, and it is no longer seen as a novelty. However, today’s video conferencing is still plagued with grainy images, muffled audio, jerky motion, dropped connections, and difficult-to-use software. Businesses sometimes avoid using basic video conferencing tools because the technology cannot provide professional-level image and audio quality.
Now, video conferencing can dissolve barriers and facilitate remote collaboration. It recreates the meeting room experience, so you can meet face-to-face with your globally dispersed teams without the expense and hassle of travel. This video conferencing technology significantly improves your team’s availability and effectiveness.
The TelePresence experience delivers high-quality audio and high-definition video conferencing over a reliable Internet Protocol (IP) network. Unlike traditional video conferencing, your meetings will look and sound as if all the participants are actually together in the same room. You can initiate or participate in a TelePresence session using tools you are already familiar with, such as a telephone interface and groupware such as Microsoft Outlook or IBM Lotus Notes. This way, you can focus more on your meeting and less on video conferencing technology.
A wireless network is any type of computer network that uses wireless data connections for connecting network nodes.
A wireless local-area network (LAN) uses radio waves to connect devices such as laptops to the Internet and to your business network and its applications. When you connect a laptop to a WiFi hotspot at a cafe, hotel, airport lounge, or other public place, you’re connecting to that business’s wireless network.
In the past, some believed wired networks were faster and more secure than wireless networks. But continual enhancements to wireless networking standards and technologies have eroded those speed and security differences.
Businesses can experience many benefits from a wireless network, including:
- Convenience – Access your network resources from any location within your wireless network’s coverage area or from any WiFi hotspot.
- Mobility – You’re no longer tied to your desk, as you were with a wired connection. You and your employees can go online in conference room meetings, for example.
- Productivity – Wireless access to the Internet and to your company’s key applications and resources helps your staff get the job done and encourages collaboration.
- Easy setup – You don’t have to string cables, so installation can be quick and cost-effective.
- Expandable – You can easily expand wireless networks with existing equipment, while a wired network might require additional wiring.
- Security – Advances in wireless networks provide robust security protections.
- Cost – Because wireless networks eliminate or reduce wiring costs, they can cost less to operate than wired networks.
