What is a LAN Switch?

Logically, we really need to start with the question, what is a LAN switch?

A LAN switch is a OSI model Layer 2 device, logically similar to a bridge. We’ll primarily focus on Ethernet (Fast Ethernet, Gigabit Ethernet) switches but much of what we say also applies to Token Ring and FDDI.

As you know, bridges learn where computers are by observing source MAC addresses in LAN frames as they pass through the bridge. After first powering on, a bridge forwards frames on all ports and is pretty much indistinguishable from a hub/repeater (except that it regenerates frames, so it does not count towards the Ethernet cable length limitation or hub/repeater 5-4-3 rule). As the bridge learns which MAC address was sourced on which port, it can then be selective about what port(s) a frame is forwarded to, only forwarding the frame to the port appropriate for the destination MAC address.

In my previous article, I wrote about Learning Windows Installation History. On the Windows side with a command can learn it, Linux operating systems, we can not learn it with command. However, we can access the installation information from the date of creation of the files or directories that were created when installing Linux operating systems and then never changed.

To do this, run the following commands on the console.

Transparent Bridge Mikrotik can be used to shoot/capture the WiFi signal from somewhere else with a certain distance.

Development in this tutorial is on the use of both devices Mikrotik as Transparent Bridge Mikrotik. So there will be two transparent bridge proxy is used to connect the client to an internet source. This will make the client as if directly connected to the Internet without going through Mikrotik source, which is characterized by the IP address obtained by the client automatically in the network with IP Router Internet sources. Double Transparent Bridge Mikrotik can also be referred to as a Repeater WiFi signal.

Tutorial How to Learn Mikrotik without RouterBoard with VMWare – For those of you who want to learn Mikrotik but do not have its router board no worry, because we can still learn Mikrotik by using iso Mikrotik file. So, in fact, Mikrotik it is Linux that is made specifically for the Router. So we do not need to have a router board, which is important to have its Mikrotik software in the form of ISO file. Mikrotik ISO file can run on a secondhand PC. But this time we will install without additional secondhand PC by running using Virtual Machine like VMWare Player, VMware Workstation,

Install Mikrotik on USB Flashdisk? Can it be? Maybe that question comes to your mind when you read the title of this Mikrotik Tutorial. Because it is usually Mikrotik is installed on the PC using the media CD / DVD or DOM installer. Maybe there is also thought that the title above means installs Mikrotik from USB Flashdisk as installation media. But that is not so.

Tutorial How to Install Mikrotik on USB FlashDisk really discusses how to install Mikrotik RouterOS into USB FlashDisk. The trick is to use the help NetInstall Mikrotik software.
