what is switch in networking A network switch (also known as a switch, concentrator, officially a MAC bridge) is a computer network device that connects devices together in a computer network by switching packets to receive, process and transfer data to a target device.

 

Switching networks in the field of computer networks are nothing more than combining multiple computers, printers, and other devices into a network so that they can communicate.

While the number of computers (or other devices) was minimal, and the amount of communication in the entire wire was possible. However, with the addition of more devices to the network, things became feverish and out of control.  If not, the station will start broadcasting.

 

 

In small networks the number of collisions was minimal, but in the case of more stations, the escalation number escalated and the communication speed dropped sharply.

 

To work around this problem

None of the stations on any of the other ports can hear this communication. This allows simultaneous broadcasting of many programs because there are “virtual private circuits” between the sender and the recipient.

 

 

 

Therefore, the networks operate at full speed all the time. Another advantage is that the network can include a mix of slower and faster devices (such as printers that communicate only at Fast Ethernet (100 Mb / s) and computers that communicate with Gigabit Ethernet (1000 Mbps, aka) 1 Gbps)) and no one in the network has this effect, because the switch slows down the sending of data to a slower device or accelerates it if necessary to a faster device.

How to locate the network connection port on the switch from the network port?

Another way is to have helper plugins and disconnect the network while you go to the switch and see which light flashes when your friend does it. Before you start, you need to know the login and password for your server/switch to “Telnet”. Go to Start: Run: enter “cmd”. Enter “ipconfig” to find the gateway and the IP address to which you are connected.

 

If you need a Mac address, and because of problems with dynamic IP addresses and changing for some reason, enter “ipconfig / all” with space before “/”. It will display “all” your IP settings, hence “everything”. Now that you have your Gateway address, IP address and Mac address (optional), you cannot start. After pressing “enter” to “ipconfig (/ all)”, or simply on a new empty line, enter “telnet” Gateway Address “”, that is: “telnet 10.0.8.1” (this is mine).

 

 

Enter Login and password so that your server/switch is connected to this device. At any time during the command, you can press the “tab” key to display all available commands. For example, we’ll use the “show” command. If you type “show” and then press the tab key, a list of unavailable commands will appear, and the cursor will be on the line after this list with the still appearing “show”. After logging in, enter “show iparp”.

 

 

We are looking for your IP address or Mac, both if your IP will be permanent (should). Just press the “tab” key until you find one of these addresses. After locating, say “10.0.10.2” (my IP address on My VLAN, it is in “10.0.8.1 (Gateway) – 10. *. *. * Range”) on the right side will show you which switch/port you are connected to. My shows 5: 2, I am on edge 5, port 2. The blade is a switching device connected on a specific stand.

For each new thread the sequence numbering for these sets of blades begins. Here’s the challenge, you need to know where to start the countdown, “where the blade begins (switching device) 1”. In our stand, we have a “patch panel” at the top of our “power and data” switches. All of these devices are connected to me in some way (going from patch panel to power and data, to the switch, to the network in the office, to my phone, to my computer). The actual “5: 2” switch meant the above does not start at the bottom of the cabinet.

 

 

These devices are very simple and have appropriate functions. The “switch” you are trying to locate, probably the 3Com or Extreme brand, combines two different elements. The switch you are looking for, being your IP Gateway address, starts after a network dump, on your phone or computer, what you do. It may take some practice, as in my case, but after you learn to know where to start, you can find the “5: 2” port in the blink of an eye

 

 

 

What are the advantages of a circuit switch network in a packet switch network?

The basis of the Packet Switched Network is Packet Switching. This network allows the service user to connect to any number of hosts via a local telephone connection / POTS port. Different hosts pay for connecting to this type of network and therefore often it is charged for connection to larger public services, such as Compuserve or The Source.A Packet Switched Network ensures efficient data transfer and lower rates than normally switched connections, which can be a great convenience if you plan a lot of file transfer between you and the host. Not only communication is efficient, virtually error-free.

 

 

During normal circuit-switched calls, there may be a drastic increase in the number of errors, resulting in poor data transfer. When using a packet switched network, it is not important to communicate with the same baud rate as the host. This device is called PAD (Packet Assembler Disassembler). PSN also provides access to a variety of information and search services. Although you can subscribe to a service to be able to use its services. The connection is usually free, with the exception of fees for some of the larger subscription services.

What is a circuit with dedicated circuit connections?

A clear physical circuit designed for direct connection of devices such as multiplexers, PBXs and host computers.In the latter case, the circuit includes an access circuit or local loop that connects the initiating device at the customer’s premises to the presence of the supplier (POP) at the edge of the operator’s network. In the case of an existing local stock carrier (ILEC), POP is usually located in the central office (CO). 

 

The dedicated circuit offers the advantages of dedicated accessibility, dedicated bandwidth, and excellent overall performance.

 The cost, however, is usually a lump sum, without a component that is sensitive to use; therefore, the organization of end users can use the circuit constantly to the maximum performance at the same cost, as if it did not use this circuit at all. The nature of traffic in a dedicated circuit is not generally limited and may include voice traffic, computer data, faxes, image, video and multimedia. The ability to integrate such a wide spectrum of traffic into one facility offers significant performance improvements.

 

Multi-user organization of users may consider a private leased network to connect pages. However, the process of designing such a network can be difficult. It is necessary to determine the endpoints in the optimal topology. The correct number of circuits and bandwidth requirements of each of them. Because the dedicated circuit includes a specific set of network elements, the circuit is susceptible to interference.

 

 

Organizations with intense communication requirements generally believe that dedicated circuits are real alternatives to switched circuits. Large data centers that communicate intensively to support applications such as data backup have traditionally chosen dedicated circuits.

what is switch in networking and do switches in the home network do?
You can use the switch to connect different devices. For example, a standard ADSL router has only a port for a single Ethernet cable. If you want to connect 2 or more computers to the Internet, you can use the switch. In this case, the ADSL router and each computer connected to the switch using a standard Ethernet cable. If you do not have an Internet connection, you can still set up a home network to share files, etc.
