What added functionality does a router have that an access point does not?
Replaces the switch device.
Manages and secures the network.
Allows Wi-Fi devices to connect to a wired network.
Communicates with the network interface card.
A router has several added functionalities that an access point does not have:
1. Routing: A router is capable of routing data packets between different networks, allowing devices to communicate with each other across different networks. An access point, on the other hand, only provides wireless connectivity within a single network.
2. NAT (Network Address Translation): A router performs NAT, which allows multiple devices in a private network to share a single public IP address. This helps in enhancing security and conserving IP addresses. An access point does not perform NAT.
3. Firewall: A router often includes a built-in firewall that provides security by filtering incoming and outgoing network traffic, protecting the network from unauthorized access and potential threats. An access point lacks this firewall functionality.
4. DHCP (Dynamic Host Configuration Protocol) Server: A router can act as a DHCP server, assigning IP addresses to devices on the network automatically. It manages IP address allocation and device connectivity. An access point does not perform DHCP server functions.
5. VLAN (Virtual Local Area Network) Support: A router supports the creation and management of VLANs, enabling network segmentation and better control over traffic flow. An access point typically does not have VLAN support.
Overall, a router has more advanced features and functionalities compared to an access point, making it a more versatile and capable device for managing and securing a network.
An access point (AP) and a router are similar in that they both allow Wi-Fi devices to connect to a network. However, a router has additional functionality that an access point does not have. Here are some added functionalities of a router:
1. Replaces the switch device: A router not only acts as an access point but also has the ability to replace the functionality of a switch. This means that in addition to connecting Wi-Fi devices to a network, a router can also connect wired devices to the network.
2. Manages and secures the network: A router serves as the central point of management and security for a network. It can provide features like firewall protection, network address translation (NAT), port forwarding, and VPN support, which are essential for managing and securing the network.
3. Communicates with the network interface card: A router communicates with the network interface card (NIC) of a device to handle routing and forwarding of network traffic. It determines the best path for data packets to reach their intended destination, ensuring efficient and effective data transmission.
In summary, while an access point primarily allows Wi-Fi devices to connect to a network, a router adds functionality such as replacing a switch, managing and securing the network, and communicating with the network interface card of the devices connected to it.
