by putting them in a common VLAN) but you can’t do that with serial ports because there is no link-layer addressing between them. In other words, serial ports require layer-3 configuration (at least a routing table entry) while Ethernet ports do not.

by putting them in a common VLAN) but you can’t do that with serial ports because there is no link-layer addressing between them. In other words, serial ports require layer-3 configuration (at least a routing table entry) while Ethernet ports do not.
Do electricians do Ethernet?
Yes they can. An electrician can wire your house up with Ethernet jacks but that doesn’t mean they’re going to go anywhere other than a wiring closet. You’ll need some sort of ISP to bring data in your house to connect to those jacks. Electricians, honestly just do it yourself.
What are the types of Ethernet?
A standard Ethernet network can transmit data at a rate up to 10 Megabits per second (10 Mbps). Other LAN types include Token Ring, Fast Ethernet, Gigabit Ethernet, 10 Gigabit Ethernet, Fiber Distributed Data Interface (FDDI), Asynchronous Transfer Mode (ATM) and LocalTalk.
What is the difference between OSI model and Internet model?
OSI makes a clear distinction between the model and implementation, while the Internet is more fuzzy. OSI is very general, whereas Internet is very specific. OSI is more flexible in that is it not tied to a specific protocol and is better able to adapt to changes in technology.
What is difference between TCP and HTTP?
HTTP is a Hypertext Transfer Protocol, whereas TCP full form is Transmission Control Protocol. HTTP is utilized to access websites, while TCP is a session establishment protocol between client and server. HTTP uses port 80 and TCP uses no port. In contrast, TCP is a Connection-Oriented Protocol.
Is Ethernet faster than WiFi?
To access a network via an Ethernet connection, users need to connect a device using ethernet cable. An Ethernet connection is generally faster than a WiFi connection and provides greater reliability and security.
Do I need Cat5 or Cat6?
If you want faster internet speeds, Cat6 is a good choice. It reduces something called “crosstalk” — signal transfers that disrupt your communication channels. If you are happy with your current internet speeds, however, Cat5 might be all you need. Typically, Cat6 cables tend to be thicker than Cat5 cables.
What do I do if I don’t have an Ethernet port?
No Ethernet Port In House
- What you are going to need is either a gigabit adapter or a USB 3.1 or USB 3.0 adapter.
- Once you have got one of these, all you need to do is plug the adapter into one of the free USB ports on your desktop or laptop.
What is Ethernet example?
Ethernet is defined as a trademark for a system that coordinates the components of a local area network. An example of Ethernet is the cable system that connects the computer network of a small business office. All new computers have it built in, and old machines can be retrofitted (see Ethernet adapter). See LAN.
Is Ethernet a layer 1 or 2?
IEEE specifies in the family of standards called IEEE 802.3 that the Ethernet protocol touches both Layer 1 (physical layer) and Layer 2 (data link layer) on the Open Systems Interconnection (OSI) network protocol model. Ethernet defines two units of transmission: packet and frame.
Is Ethernet parallel or serial?
Ethernet (IEEE 802.3) is the most broadly used network protocol these days. It is also a serial communication standard. Since it is used in so many modern networks, the question is why hasn’t it replaced RS-485 and its other variations (RS-232, RS-422).
What is needed for Ethernet connection?
Ethernet cables, also known as RJ-45, CAT5, or CAT6 cables, have a square plug with a clip on each end. You’ll use an Ethernet cable to connect your computer to your router. The cable connecting your modem and your router is an Ethernet cable, but don’t use that one, as it is important where it is.
What mean Ethernet?
Ethernet (/ˈiːθərnɛt/) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3.
How do I get an Ethernet connection?
How to connect an Ethernet cable?
- Plug an Ethernet cable into your computer.
- Plug the other end of the Ethernet cable into one of your hub’s Ethernet ports.
- You should now have established an Ethernet connection, and your computer is now ready to start surfing the internet.
Can I use Ethernet port as serial?
Since the introduction of the USB protocol, you don’t see many serial devices anymore. Nevertheless, a serial-to-Ethernet adapter allows you to connect most serial devices to an Ethernet port on your computer or a network router or switch.
Which came first TCP IP or OSI?
The TCP/IP model, which is realistically the Internet Model, came into existence about 10 years before the OSI model. The four-layer Internet model defines the Internet protocol suite, better known as the TCP/IP suite.
What OSI layer is TCP IP?
Transport Layer
Is TCP and IP the same?
TCP and IP are two separate computer network protocols. IP is the part that obtains the address to which data is sent. TCP is responsible for data delivery once that IP address has been found.
Can I plug a router into a router?
Connect a Second Wireless Router Home wireless routers can be connected using Ethernet cable in the same way as wired routers are connected. Connecting two home routers over wireless is also possible, but in most configurations, the second router can only function as a wireless access point instead of a router.
What is difference between serial and Ethernet?
Ethernet is a faster, more reliable, and more flexible communication technology than serial. Depending on the specifications of your computer, you may experience communication problems with a serial network, in which case you will have to use an Ethernet network.
Can I plug an Ethernet cable into the wall outlet?
Your wall socket is probably not connected to a router or a modem. If you want to use it, find the cable that goes into it an plug it into your modem’s Ethernet port. The wall socket is not actually a magic Internet source. It is just a continuation of a cable that must be connected somewhere to work.
What is difference between OSI model and TCP IP model?
OSI refers to Open Systems Interconnection whereas TCP/IP refers to Transmission Control Protocol. OSI follows a vertical approach whereas TCP/IP follows a horizontal approach. OSI model, the transport layer, is only connection-oriented whereas the TCP/IP model is both connection-oriented and connectionless.
Are LAN and Ethernet the same?
A LAN port is also known as an Ethernet port. Both terms refer to exactly the same socket on computers, servers, modems, Wi-Fi routers, switches, and other network devices.
Can I install Ethernet myself?
Installing a wired Internet port is a task that can range from difficult to impossible, and it’s always expensive if you can’t do it yourself. They let you set up wired Internet ports in just minutes without having to run cables or cut through walls—you can use your home’s electrical wiring.
What OSI layer is Modbus?
application layer
