What is a router? Explain its features. Advantages and disadvantages of routers

A router is a networking device that forwards data packets between computer networks. It connects multiple devices on a single network and uses routing tables to determine the best path for data to travel from one network to another. Check online for the router price in India.

Features of a router include:

• IP addressing and subnetting: routers can assign unique IP addresses to devices on a network and divide a network into subnets for better organization and security.
• Network address translation (NAT): routers can hide the IP addresses of devices on a private network behind a single public IP address.
• Firewall: routers often have built-in firewall capabilities to protect a network from unauthorized access and malicious traffic.
• Quality of Service (QoS): routers can prioritize certain types of network traffic, such as video or voice, for better performance.

Advantages of routers include:

• Improved network organization and security: routers can segment a network into smaller, more secure subnets and assign unique IP addresses to devices.
• Increased network capacity: routers allow multiple devices to share a single internet connection.
• Enhanced network performance: routers can prioritize certain types of network traffic for better performance.

Disadvantages of routers include:

• Configuration complexity: routers can be difficult to set up and configure, especially for non-technical users.
• Limited flexibility: routers may not be able to handle certain types of advanced networking requirements, such as VPNs or large-scale network deployments.
• Limited scalability: routers may not be able to handle large numbers of devices or high levels of network traffic.

Where are routers used?

Routers are primarily used in computer networks to forward data packets between networks. They are commonly used in the following settings:

1. Home networks: Routers are often used to connect devices. Such as computers, smartphones, and smart home devices to the internet in residential settings.
2. Business networks: Routers are used in small and large business networks to connect devices. Such as computers, servers, and printers to the internet, and also to create a LAN (Local Area Network)
3. Internet Service Providers (ISPs): ISPs use routers to connect customers to the internet. Typically via a modem.
4. Data centers: routers are used in data centers. To connect servers, storage devices, and other network devices to each other, and to the internet.
5. WAN (Wide Area Network): Routers are used to connect multiple LANs. In different geographic locations and create a WAN
6. Mobile networks: Routers are used in mobile networks to connect cell towers and base stations to the internet, and to route data between mobile devices.
7. Public places: routers are used in public places such as airports, hotels, and coffee shops to provide wireless internet access to customers.

How does a router function?

Consider a router an air traffic regulator and information parcels as airplanes went to various air terminals (or organizations). Similarly, each plane has an exceptional objective and follows a special course. Every bundle should be directed to its objective as effectively as could be expected. Similarly that an air traffic regulator guarantees that planes arrive at their objections without getting lost or experiencing a significant interruption en route, and a router guides information parcels to their objective IP address.

To coordinate bundles really, a router utilizes an interior steering table — a rundown of ways to different organization objections. The router peruses a parcel's header to figure out where it is going, then, at that point, counsels the directing table to sort out the most effective way to that objective. It then, at that point, advances the parcel to the following organization in the way.

What are the various kinds of routers?

To interface a LAN to the Web, a router first necessities to speak with a modem. There are two essential ways of doing this:

Remote router: 

A remote router utilizes an Ethernet link to interface with a modem. It circulates information by changing over parcels from parallel code into radio transmissions, then, at that point, remotely communicates them utilizing receiving wires. Remote routers don't lay out LANs; all things being equal, they make WLANs (remote neighborhoods), which associate numerous gadgets utilizing remote correspondence.

Wired router: 

Like a remote router, a wired router likewise utilizes an Ethernet link to interface with a modem. It then utilizes separate links to interface with at least one gadget. Inside the organization, make a LAN, and connection the gadgets inside that organization to the Web.

Notwithstanding remote and wired routers for little LANs, there are many particular sorts of routers that serve explicit capabilities:

Center router: 

Not at all like the routers utilized inside a home or private venture LAN. A center router is utilized by enormous companies and organizations. That sends a high volume of information bundles inside their organization. Center routes work at the "center" of an organization and don't speak with outer organizations.

Edge router: 

While a center router solely oversees information traffic inside an enormous scope organization. An edge router speaks with both center routers and outside organizations. Edge routes inhabit the "edge" of an organization and utilize the BGP (Boundary Door Convention). To send and get information from different LANs and WANs.

Virtual router: 

A virtual router is a product application that carries out a similar role as a standard equipment router. It might utilize the Virtual router Overt repetitiveness Convention (VRRP) to lay out essential and reinforcement virtual routes. Would it be advisable for one to fall flat.
