Networking in IoT age for big opportunities (1 of 3)

Networking Basics

In most cases, this connection is made via electrical cables that carry the information in the form of electrical signals. Other types of connections are used, too. 

For example, computers can communicate via fiber optic cables at extremely high speeds by using impulses of light. And in a wireless network, computers communicate by using radio signals. Client computers Server computers Network interface- network port Cable: Computers in a network are usually physically connected to each other using cable Switches: You don't typically use network cable to connect computers directly to each other. Instead, each computer is connected by cable to a central switch, which connects to the rest of the network Wireless networks: In a wireless network, most cables and switches are moot. Radio transmitters and receivers take the place of cables. Of course, the main advantage of wireless networking is its flexibility: no cables to run through walls or ceilings, and client computers located anywhere within range of the network broadcast. Network software: What really makes a network work is software, which has to be set up just right to get a network working 

What is Network: A network is simply two or more computers, connected, so that they can exchange information (such as e-mail messages or documents) or share resources (say, disk storage or printers).

Benefits of network:

- Sharing resources

- Sharing information

- Sharing applications
