Wondering Why Do I Need A Router? Avail the Effective and Know the Usage of a Router
To define, a router is an electronic device which transmits data packets with the help of the networks. You can connect the router with at least two networks.Moreover, this device also helps to connect two WANs or LANs or a LAN and its network of the ISP. Generally, Routers are placed at gateways, the places where you can get connected to several networks. One of its effective usages is to track the computer that made a request to the Internet to responses back to the computer only with the help of the assigned number.
If you are tired by searching ‘do I need a router’, then you are in the correct place. Here in this article, we are going to provide a beneficial guidance about the necessity and usage of a router. Hence, you need to go through the below article thoroughly.
Know the Necessity of a Router for Computer
When you avail the Internet service from any ISP or Internet Service Provider, they will often install a device in your place, which is known as the modem or private gateway. It provides you a strong Internet connection. Some of the devices come with only one RJ-45 port or one Ethernet cable, which offers Internet service. But others may have built-in wireless or wired router providing multiple connections. If you have only one Internet connection, then connecting that router between the modem and your system can benefit you a lot. Have a look, at the below points to know is a router necessary for your system?
Sharing of the Internet Connection:
A gateway or modem with only one port gives only a single common Internet Protocol address to your home or a particular area. This IP address acts like the mailing address, that allows the servers to know where to send the data you have requested. Two devices can’t share the similar public IP address, so to connect several devices, you need to use the router. Besides, a router can create a modest private network in your place, and provide several connected devices with its private IP number.
The network address translation software of the router or NAT connects all the outbound information requests from the individual IP addresses and as well as addresses them from the common IP address. If the data is transferred to the common IP address, then the NAT software classifies all the data and transfers it to the individual IP address of the machine that requested it.
Most of the gateways or modems do not present broadcast Internet connections, also if they have a built-in router. To offer broadcast access for Computers and other machines, you have to attach a wireless router, that often combines Ethernet cables, or a Wi-Fi access point, that simply presents a broadcast connection. Depending on which type you prefer to attach, the system will need to be configured properly before going to use it. You can perform this by following the instructions of the manual of the owner to obtain the configuration tool or configuration program based on the browser.
Now you can configure your personal IP address of your device. With the help of the WPA2, the powerful, WEP or WPA, you can restrict the outsiders from being capable to obtain the data on your personal network. In addition, you also can restrict the access of the Internet only to the approved devices.
Content Filtering and Network Protection:
Most of the routers come with an inbuilt software firewall. When you configure it in a proper way, it blocks outsiders to access your private network to steal the data or install corrupted software and it can block that software from being fixed to your system while using the Internet. In some cases, the firewall also can be applied to prevent access to the websites which you may consider inappropriate or harmful for you and as well as for your home.
Printer and File Sharing:
A router can help you to share files between systems on the network and also to print to remote printers because it can build a single network. You require this to support file and as well as print sharing in Windows or use related settings in another Operating System.
Know The Functions of a Router
Before you use any router, it is essential to know its functions and features. Doing this would give you better guidance on how to use the router. Hence, follow the below points to know the functions of a router.
- Routers allow various computers to share a basic Internet connection from your Internet Service Provider. It also connects to the DSL input, wire, or by 3G mobile devices with the help of the USB modem.
- A Router supports Network Address Translation or NAT. That means the common IP address is consigned to the router, and not to other Computers on the local side of the router.
- A router also can enhance the security level.
- Some of the routers also support the latest security like VPN, that helps the consumers of the business at home to log in safely to the network of the business.
- Some routers also have firewalls to provide significant stability and as well as protection against hacking into the network.
- A router can monitor the usage of the network and also can transmit email alarms when any unnatural things happen.
- Some broadcast routers also support WPA. This provides you a strong encryption for the Wi-Fi data.
- Routers also have the Parental Controls facility. This means you can stop children to access the restricted http// websites.
In the above discussion, we have discussed effective points on the query why do I need a router. We hope, this guideline will help you to understand the details of a router and make your task easier.
