Basics of Networking

Terminology understanding of networks

What is a Network ?

A network is a collection of computers and devices that are connected together to enable communication and data exchange.

Protocol

a set of rules and standards that govern how data is transmitted over a network. Examples of protocols include TCP/IP, HTTP, and FTP,ICMP.

ISP(Internet Service Providers)

These types of Networks give permission to take Network Capacity and Functionality on lease from the Provider. Service Provider Networks include Wireless Communications, Data Carriers, etc.

DNS(Domain Name System):The Domain Name System (DNS) is a protocol that is used to translate human-readable domain names (such as www.google.com) into IP addresses that computers can understand.

Hub:a hub is a device that links multiple computers and devices together. Hubs can also be referred to as repeaters or concentrators.

Spoke:The Hub Spoke System, also known as a star scheme, is a special transport network consisting of a central hub.

Firewall: A firewall is a security device that is used to monitor and control incoming and outgoing network traffic. Firewalls are used to protect networks from unauthorized access and other security threats

Switch:A network switch is equipment that allows two or more IT devices, such as computers, to communicate with one another.

Router: A router is a device that connects two or more packet-switched networks or subnetworks

Ports:A port identifies a specific connection between network devices. Each port is identified by a number. If you think of an IP address as comparable to the address of a hotel, then ports are the suites or room numbers within that hotel. Computers use port numbers to determine which application, service, or process should receive specific messages.

Types of Enterprise Networks

• LAN: A Local Area Network (LAN) is a network that covers a small area, such as an office or a home. LANs are typically used to connect computers and other devices within a building or a campus.
• WAN: A Wide Area Network (WAN) is a network that covers a large geographic area, such as a city, country, or even the entire world. WANs are used to connect LANs together and are typically used for long-distance communication.
• Cloud Networks: Cloud Networks can be visualized with a Wide Area Network (WAN) as they can be hosted on public or private cloud service providers and cloud networks are available if there is a demand. Cloud Networks consist of Virtual Routers, Firewalls, etc.
