路由器:
路由器被称为网络中的连接设备。它用于为数据包选择最短路径以实现其目标。路由器的主要目的是同时连接不同的网络。和防火墙一样,它也作用于网络层,但也作用于物理层,以及OSI(开放系统互连)模型的数据链路层。与防火墙不同,它在路由网络之前不包括加密。路由器不能保护网络免受威胁,但它包括共享条款以在网络之间共享 Internet 连接。
防火墙:
防火墙是指定版本的路由器。里面的所有数据包进入或丢弃网络都通过防火墙,并在检查防火墙是否允许之后。所有流量都必须通过防火墙,只有经过授权的流量才能通过。防火墙必须强大。它是一个位于两个网络之间的系统,它在这些网络之间实施访问控制策略。与路由器一样,它也适用于 OSI 模型的网络层。与路由器不同,防火墙在传输之前使用加密来加密数据。防火墙不共享网络,但它包括保护网络免受威胁的保护措施。
让我们看看路由器和防火墙之间的区别:
S.NO | Firewall | Router |
---|---|---|
1. | A firewall checks the threat from the incoming packets. | A router is a way to connect various networks simultaneously. |
2. | The firewall works on network layer and transport layer of the OSI(Open Systems Interconnection) model. | While the router works on the physical layer, network layer and data link layer of the OSI(Open Systems Interconnection) model. |
3. | The firewall uses encryption before the transmission of data. | Whereas router does not use encryption. |
4. | A firewall cannot share network. | While router share internet connection between the networks. |
5. | A firewall may occur inside a router. | While a router may not occur within a firewall. |
6. | A firewall filters as well as regulates the data. | While a router manages traffic to the desired target. |
7. | A firewall maintains state table which gives information on the state of flow. | While a router does not maintain any state table for the information on flow state. |
8. | Firewall is generally used in the protection in core network of computer. | Router is generally used in routing and ending of WAN link. |
