Can anyone explain to me in layman s terms what the switch does

The switch has the function of isolating network segments and increasing bandwidth.

In the process of building a network, switches basically replace hubs as common equipment in the network.

The network formed by switches is called a switched network, such as an interchanging Ethernet LAN; Networks built with hubs are shared networks, such as shared Ethernet LANs.

The structure of a shared Ethernet LAN does not allow two or more devices to send information at the same time, and if they send information at the same time, a data conflict will occur on the bus, and all computers that share the bandwidth of this bus will detect this conflict, and will be affected by this conflict, resulting in data transmission failure. The network it consists of constitutes a collision domain. In the same collision domain, network devices will compete for this shared bandwidth, resulting in an increase in data conflicts and a decrease in network data transmission efficiency as the number of users increases.

Compared with a shared LAN, a switched LAN uses a switch as a network device. It has high data transmission efficiency, is suitable for large data volume and very frequent network communication, and can be widely used to transmit various types of multi-** data.

The introduction of switches has turned the "exclusive" network structure of the traditional LAN, which can only serve one user at a time, into a parallel processing system where ports can be used at the same time. Transmit data in parallel and monopolize port bandwidth, so that when working on one port, it will not affect the data transmission of other ports. And the switch works in a full-duplex state.

It doubles its data processing power.

Generally speaking, a switch is a device for data exchange, and its function is to connect a multi-functional computer to a local area network, but the connection port is theoretically no more than 255. The 10M and 100M switches refer to their port bandwidth, which is the transmission speed when connected to a computer.

Switching equipment is used to form a star LAN (which is what we commonly use today). If you have to form a ring network, you don't need to. Stringing together a copper uranium cable for a computer is a ring.

The switch is the second layer of OSI Layer 7 and is mainly used for data pin switching. He is faster than the router** packets. He works in the same network segment. belong to the same broadcast domain.

In short, it is a device for data exchange.

Several computers are connected to a computing LAN to enable data exchange and line sharing.

It is to transform from the original ** to the digital **.

The switch has no function, it is equivalent to a hub, the only thing that is better than the hub is that in data communication, it is an exclusive bandwidth, the hub is a shared bandwidth, and the switch will automatically remember in the process of data exchange, saving time for sending data later.

Hello, the switch is a few more interfaces, devices that can access the Internet together, 2 trillion network speed is definitely slow, a few more 2 trillion, it is better to upgrade directly to 4m or higher bandwidth, so that it will not be slow, a few people in the router have a relationship with bandwidth, you have a large bandwidth, and the speed is also fast.

The router only has one more dial-up function than the switch, your two-megabit network cable is like a total water pipe, the switch and the router are like multi-purpose connectors, the more you connect with one in and out, the less it is allocated to everyone. How can there be a few more two-megabit network cables, then the operator will drink the northwest wind.

Let me tell you this, no matter what you use, the bandwidth you access to the device is fixed, and it won't affect what device you change. So there's no need to change it. Multi-person sharing bandwidth is definitely slow.

Generally speaking, the switch plays the role of data exchange.

If you want to share dial-up Internet access, you still use a router, the switch cannot dial up, and the switch is at most an increase in the number of LAN ports of your router for you.

1. What is a switch?

The switch, also known as the switching hub, is a network equipment that conducts the best electrical signals, which can provide exclusive electrical signal paths for any two network nodes connected to the switch and improve the efficiency of broadband utilization!

Through the switch, the access information can be regenerated, and then through the internal processing to the specified port, to achieve the role of automatic addressing and switching, so as to avoid the problem of port conflicts, prevent transmission conflicts, and improve network throughput!

Second, the basic role of the switch.

1. Hub: The switch has a large number of built-in ports that can be connected by cables, so it can be used as a hub to achieve the purpose of deploying a star topology network.

2. Repeater: The switch can be the same as the repeater, and regenerate an undistorted square electrical signal at the time of the first frame.

3. Bridge: The switch can practically use the same ** and filtering logic on its built-in ports, and has the function of a bridge.

4. The switch can divide the deployed LAN into multiple conflict domains, while the U.S. conflict domain can have independent bandwidth to improve broadband utilization efficiency.

3. The main functions of the switch.

The main functions of the switch include physical addressing, network topology, error checking, frame sequence, and flow control. Switches also have new features such as support for VLANs (Virtual Local Area Networks), support for link aggregation, and even firewalls.

4. Classification of switches.

Common switches are generally Ethernet switches, and there are also voice switches, optical fiber switches, etc.

Without so much nonsense, simply say, the exchange plays the exchange of data. Transmit the data of the connection between the users of the office. It can transmit data exchange between external network and intranet.

Generally speaking, a switch can connect most terminals (computers) together, they can access each other, and if the switch is connected to an Internet network, then all computers can also access the Internet together

a. **Filtering.

b. Loop avoidance.

c. Routing**.

Network equipment for electrical signals**.

A switch is a type of network equipment used for electrical signals**. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. The most common type of switch is an Ethernet switch. Other common ones include voice switches, fiber optic switches, etc.
