What is Switch and Hub, and its Functions

Switch and Hub. What difference does it make?

Switch

It's a multi-spots device (VENTS 5 Port-8 Port-24 Port-48 port) is connecting the devices and some of them in a single LAN. Switch and hardware. (know ip - we will speak in detail in upcoming lessons)

The straight have different port (Openings in the operator) of which 48 port and 24 Port-16 Port-8 Port-5 Port. And every port (slot) in the switch comes out of a cable to only one device (it can't be shared at the port one more than the device) and the starter is installed in the RJ45, and also the cables also have the speed of the switch. The concept of Ethernet (protocol related to the intra net is responsible for communication between devices in the intra net).

Types in speed:

Each switch has different speeds of it:
Ethernet: an switch speed of 10 Mega-10 Mbps.
Fast Ethernet: Speed 100 Mbps.
Giga Ethernet: Speed 1000 Mbps.

All these same straight can easily be distinguished only by reading the hole or the label behind the switch or the catalogue with the switch when it is purchased and through which the quality of the switch and the speed of different openings can be found.

Also, cable can be installed in the ignition, but it's better to share the ratio and proportionality between cable and switch,

Example:Cable Ethernet + Cable Cat 5 Switch.Cable Fast Ethernet + Cable Cat 5 E Switch.Cable Giga Ethernet + Cable Cat 6 Switch.

Why do we do that, like we said, we can ride any cable, whatever it is in the switch, and it works all the time, but it's better to speed up the cable speed to match the speed of the switch so that the service is better and better and faster, Cable Cable Cable 5 with swish open speed will do the service for sure but not at the required level because the speed of the cable will be less than the speed of the switch and therefore we will not benefit from both as required (speed transfer) Data center will be slow because the speed of the cable is higher than the speed of the switch and also if we deliver the cable cat 6 with switch Ethernet will also serve the service but not properly because the speed of the cable will be higher than the speed of the switch The velocity of the data center will be weak because the speed of the cable is higher than the speed of the switch and so.. and the straight vary at the rate of speed, as well as the number of openings, whenever the speed of the vents is higher, the higher the price of the On the market.

Operator's m.o.

He works in a smart way to transfer data center by creating a table in two columns:
Goal Destination Pc5
Source Source

Example: Switch + 5 computer devices

Device No. 1 (source) sent data (film, song, file) to device no. 5 (Target), the starter is sending it first to all devices (Pc1, Pc2, Pc3, Ps4, Pc5, and when device number 5 the data center and not return it again to the starter, the operator knows that device number 5 is the target, and it is stored in its schedule. Don't repeat the same error sending data center to all devices again.

Flame Hub

It's a a device that can only be segregated from the operator, and it used to be used in an old one, but he was dealing with the data as if it were electrical waves and not dealing with it. Data, and don't understand anything, and it's simply like the power of electricity that delivers electricity to the video, TV and cassette together, it doesn't understand something (does not know IP) and sends the data with the cool system, which is when a member wants The network sends data no matter how large it is. It sends it to all devices and the data owner only accepts it. The rest of the organs are you back to flame, causing problems in the network and slow.

The Word " broadcast " is that it means " broadcast whether it's radio or Television, etc.

Example: Radio Radio. The Radio is broadcasting the content via the radio but does not require the arrival or hearing of the radio from each user and does not require that each radio is compatible with the radio frequency and does not require every listener to hear the broadcast.
If device no. 1 (PC 1) sends a message (may be Emile, song or film, etc) to device no. 5 (PC 5) the hub was receiving the message from the And instead of sending it directly to device 5, it was sent to all devices (PC 1, Pc2, Pc3, Pc4, Pc5) and device number 5 will do For the message to him and he will not return it to hub, the rest of the devices will return the message to hub again (not directed to it) and then hub will receive these messages from the devices
(Pc2, Pc3, Pc4) and send it back to the device no. 1 (Pc1), which is sent back to hub with the aim of delivering it to device 5 (Flame). He received the message, and this is how this process goes on a lot in the network, passes through the devices, flame and cables, which eventually leads to stifling the network and its abdomen, thereby causing the so-called loop or the sudden death of the network.

Loop: the meaning of this term is the "death of the network" and it means that the continued of data center within the network is in an endless loop and thus leads to the death of the network, i.e. the lack of reception or reception in the network and stop it.

And we deduce from the earlier that he was a stupid device in his work, which led to his failure.

What's the difference between the switch and hub?


Flame B and switch deals with the title of the network card, means the device to be dealt with.
The Hub sends the data center to all computers or related web devices, while the switch sends the data center to the target device only.
The number of hub ports ranges between 4 and 12 ports, while the number of switch ranges between 8 and 48 ports.
The Hub doesn't have an operating program. The switch is probably an operating program.
Hub costs are often lower than the cost of the switch.

At the end of our lesson, we've got a full knowledge of the switch, the way it works and its kind in terms of speed, and also we know about the flame and the way it used and the difference between them. It's a simple contribution to the delivery of a statement
