An access point is a device, such as a wireless router, that allows wireless devices to connect to a network. Most access points have built-in routers, while others will need to be connected to a router to provide network access. In any case, access points are typically hard-wired with other devices, such as network switches or broadband modems.
Wireless Access Point vs Wireless Router, You can find access points anywhere whether it is home, business, even in public places. In most homes, this access point is a wireless router connected to a DSL or cable modem. But at the same time, some modems also have the facility of wireless, so that they make the modem itself an access point.

Where is a Wireless Access Point Used?
- Large businesses are provided with multiple access points, so that employees can easily connect to the central network, rarely from any location (the range of locations increases).
- You can easily find a public access point in any number of shops, coffee shops, restaurants, libraries, and other locations. Some smart cities also provide public access points in the form of wireless transmitters that are connected to streetlights, signs, and other public objects.
- Where access points are used to access the Internet wirelessly, some are also used to provide access only to a closed network. For example, a business may provide its employees with a secure access point so that they can access files remotely from a network server.
- Most access points provide Wi-Fi access, but it is possible for an access point to refer to a Bluetooth device or some other type of wireless connection. But the main purpose of most access points is to provide Internet access to the connected user.
- The term “access point” is often used as a synonym for “base station”, but from a technical standpoint, a base station is only suitable for Wi-Fi devices. It is also called WAP (or Wireless Access Point). But WAP is not commonly used like AP (Access Point) is used.

What is a Wireless Router?
You can think of a router as a small electronic device that connects or connects several computer networks together through a wired or wireless connection. Understand that a Router connects a computer network to another computer network or connects a computer network to the Internet.
Do you know what a router is and how does this networking device works? If you have any other questions along with these questions in your mind, then I am going to answer them in today’s article.
Where is a Wireless Router Used?
- You must have heard the name of Router because it is used for the Internet nowadays. Whenever you access the Internet except for the mobile network. Then you understand that you are accessing the Internet from a Wireless Networking Device.
- Still don’t believe my words. You once ask anyone, brother, do you use any device for WiFi. His answer will definitely be related to today’s article. The question also comes, what is the work of this device.
- Think you are a postman and your job is to deliver letters to different houses every day. But you can send the letter only when you have their address and with this, you will also know the way to go to the house of the letter.
How does Router work?
- As you know, a Router works to forward packets from one network to another. It can also be said that it sends packets from Source to Destination Address. Its main job is to receive the packet and deliver it to the receiver.
- You sent a Facebook message from your computer to your friend who is currently in Delhi. First, the message gets converted into a packet and reaches the nearby router. Now the Router checks the Routing Table with the Routing Protocol.
- All the nearby routers in the routing table have their address and path distance. Then after this, the packet is forwarded to the nearest router, in which the IP address of the receiver remains.
- As soon as the packet reaches the next router, it also checks the shortest path again and is sent to the next router. In this way, the packet reaches the receiver computer.
- A Router also connects many networks and also maintains its Routing table. maintain means keep updating. Each router keeps the information about the router around him.
- Routing Protocol resides in all the routers, with the help of which they communicate with each other. And along with this share the information of their connected networks among themselves, update the routing table. This is how this networking device works.

- Central Processing Unit (CPU):
CPU which is a brain that runs special software named os. There are some OS like Junos, Juniper RUN Routers, and Cisco IOS that run Cisco Routers. This operating system manages all the components of all the routers.
- Flash Memory :
Every electronic device requires memory in which the operating system is stored. Compare Flash memory with a computer, then it is a hard disk only. This Flash memory contains Routing Algorithm, Routing Protocol, Routing Table Store.
- Non-Volatile RAM:
You must have understood from its name that it is Memory Permanent. Inside it is the backup and startup Version Store of the Operating System. Whenever the router boots, programs are loaded from this memory itself.
Whenever the router is on, then the operating system is loaded into RAM. After this, the Router determines the Routes. From other Routers, it sees Routes Information (via RIP RIP (v1 and v2), OSPF, EIGRP, IS-IS, or BGP).
ARP tables, routing tables, routing metrics, and other data are stored inside RAM. ARP tables, routing tables, routing metrics With the help of these, Packet Forwarding Process Speed is done.
- Network Interfaces:
There are always many network interfaces in routers. There are many drivers in the operating system. With the help of these drivers, the routers get to know in which port which network’s WIRE is connected. There is the ability to learn Routes from other Routers and the packet is transmitted on the correct route.
All the work of managing and configuring the router is done in the console itself. Configuration and troubleshooting commands are provided from the console.
Wireless access point vs. wireless router – which should you use?
- Commonly, wireless routers assist residential rental households and small companies, where sole equipment that stirs AP and routing functionality can readily fulfill the moderately reasonable user demand. A wireless router can’t efficiently plate to evaluate escalating network needs, however, bringing about it ill-suited for wireless LANs (WLANs) that predict considerable growth.
- Rather, wireless APs are used in enormous businesses and venues, which need many APs to deliver service — for example, to wrap a substantial physical area or to help thousands of users. As demand grows, network managers can add extra APs, occurring in more scalable structures than wireless routers would enable.
- In enormous WLANs, it usually makes a point to have several APs feeding into a single, distinct router. Wireless stations can then be dealt with as one huge subnet, which is helpful when a user is strolling from one AP to another. Another benefit of this model is wireless access management can be focused on one router rather than dissipating across various dominant routers, facilitating more profitable and helpful network management.
