What is Networking? Networking , also known as Computer networking involves transporting and exchanging data between nodes (such as computers, servers, smartphones, and IoT devices) over a shared medium within an information system.
Features of Networking
One of the most important features of a Computer Network is that with their help you can easily share the data between different systems that are connected with each other through transmission media. Thus, resources can be easily shared between two or more devices over a network. Data Sharing Features Reliability With the help of Computer Networks there are fewer chances for the occurrence of failure and in case if there is any failure then recovery is fast.
Security is one of the main characteristics of Computer Networks, Thus a computer network should be secure so that the data transmitting over the network should be safe from any unauthorized access. Security Features Performance The performance of a computer network is measured using response time and with the help of the speed of data transmission. For better performance, the response time of sending and receiving data from one node to another should be minimum.
There must be a central server for the computer network and this server must keep the backup of all the data that is shared over the network. And at the time of failure in the network this central server helps in the faster recovery. Backup Features Software and Hardware Compatibility In the Computer Network, there must not be any limitation for all the computers in a computer network to use the same software and hardware. With the help of a Computer network, it becomes very easy for all of us to share our knowledge and ideas with others for example: via email messaging, via video conferencing over the internet, everything becomes easy .
These features collectively enable efficient communication, resource sharing, and secure data exchange in computer networks!
Modem Router Components of Networking A modem (short for modulator-demodulator ) connects you to the Internet. A router creates your private network and allows multiple devices to share the Internet connection.
Repeater Switch Components of Networking A network switch is a wired device that expands the number of ports on your router. Also known as a wireless range extender , a repeater boosts signal strength from your wireless router.
End Devices Transmission media Components of Networking A Transmission media (wired or wireless) carry data between devices. Examples include Ethernet cables and Wi-Fi signals. These are the devices connected to the network, such as computers, smartphones, printers, and servers.
Protocols Networking Devices Components of Networking These include switches, routers, wireless access points, and firewalls. Firmware operates these devices. Software monitors, manages, and secures the network. Network protocols define rules for communication. Examples include TCP/IP, HTTP, and DNS.
Types of Networks
Uses physical media (e.g., Ethernet cables) for data transport. Wired Networking
Wireless Networking Relies on radio waves for data transmission (e.g., Wi-Fi).
Types of Networks LAN PAN WA N SAN MAN Local Area Wide Area Metropolitan Area Personal Area Storage Area
Types of Networks LAN (Local Area Network) : Connects devices within a limited area (e.g., an office). WAN (Wide Area Network) : Spans large geographical regions (e.g., the internet). MAN (Metropolitan Area Network) : Larger than LANs, serving cities or regions. PAN (Personal Area Network) : For individual devices (e.g., syncing a phone and laptop). SAN (Storage Area Network) : Specialized for block-level storage access.
