Difference between Modems, Routers and Switches

Modems, routers and switches are included in related to connection of computers to the Internet. The modem usually decodes and encodes information while the router, coordinates the data gathered by modem to gadgets inside of that system. A switch is actually a plug and play gadget that requires no design at all to interconnect various PCs. The modem acquires the data, and router appropriates it to various gadgets such as PCs and telephones. In this article we are going to explain the difference between these three terms i.e. Modem, routers and switches.

Modem

A modem is a gadget that arranges the connections with ISP through phone line. Generally modems were remaining single gadgets that can be associated directly to PC or to router. It connects with the router by means of the standard RJ45 and to phone line by means of the littler RJ11. Its purpose is basically to decode and encodes information starting with one convention then onto the next since phone lines don’t utilize the similar signaling and transmission strategies that are utilized as a part of PC systems. In view of this, information is not being monitored by the modem and some potential danger would in any case experience to the system.

 Routers

A router is a gadget in a system that associates PC systems, for instance, connecting a home system with internet. Routers are actually the workhorses that exchange parcels of information between systems to build up and manage correspondence between two hubs in an internetwork. Router work at Layer 3 of the OSI model; a router utilizes the target IP address in an information bundle to figure out where to promote the parcel.

 Switches

A system switch allows the gadget to connect jointly on a single PC system. A switch is likewise known as switching hub, MAC Bridge, bridging hub. Switches utilize MAC locations to forward information to the right destination. A switch is viewed as a Layer 2 gadget, working at the data link layer; switches utilize parcel switching to get, prepare and forward information.

Modems VS routers VS switches

  • Definition:

A modem is a device which transmits and gets information through phone lines, and is utilized to connect single PC or a whole home PC system to internet.

A router is actually a device that leads to connect a system to other systems.

A switch is a device that is utilized to associate numerous gadgets together on a PC system.

  • Purpose:

A modem is a device which provides connection with the internet with the help of transmitting and accepting information over phone lines.

A router is a device which directs the information in a system. It usually passes information between home PCs, and between PCs and modem.

A switch is a device which permits to connect more than one device and ports and it is also helpful to make security.

  • Connections:

A modem can just connect with only one device that either includes a home’s computer or router.

A router can helpful to connect with more than one device in a system that either includes by Ethernet links or WiFi.

 A switch is mostly utilized for wired connection in a system.

  • Security:

A modem is a device which does not provide any security as it only encodes or decodes the data, thus it goes on any potential danger to associated PCs.

A router looks at information packets to decide their target, thus can have firewalls to monitor assaults on the system that shows it provides the security.

Switches provide the security measures.

Conclusion

From the above article we can end up with the discussion that a modem is a device which transmits and gets information through phone lines, and is utilized to connect single PC or a whole home PC system to internet, a router is actually a device that leads to connect a system to other systems and a switch is a device that is utilized to associate numerous gadgets together on a PC system. A modem is a device which provides connection with the internet, a router is a device which directs the information in a system and a switch is a device which permits to connect more than one device and ports and it is also helpful to make security. A modem can just connect with only one device, a router can helpful to connect with more than one device in a system, a switch is mostly utilized for wired connection in a system. A modem is a device which does not provide any security while a router and switch provides security.
