You probably heard about switches for LAN but not a lot of people heard about KVM switches. So what exactly is KVM switch?

If we look at the name, it is a shortcut for Keyboard, Video & Mouse and the original idea was to have multiple computers but one keyboard, mouse, and monitor. These peripherals would be connected to the KVM switch and other computers could all use one set of these on the fly when needed.
The technology behind the switch is a little interesting since it will actively fake signals to other computers that are not using peripherals. Once they are switched to them the transition is smooth and not noticeable. In old days these switches were more important than today since on every mouse or keyboard disconnection you had to reboot the computer, and although today that is not the case CPU will still detect disconnection and on the next connection it will run through the ID of the device and try to use the existing driver and if peripheral was connected in other USB port, it will install the same driver but connect it to the new USB port.
This type of reconnection can slow down work and place unnecessary load on the CPU so that is why KVM will fake connection in order to make switching externals on the computer smooth and in nick of a time.
Modern KVM switch
These days modern KVM switches will offer you more options than just being able to switch between keyboard, mouse, and monitor. Modern switches now offer Lan, audio, and many more various options.
There are also different kinds of switches offering you only one option, like for example just a Video switch that will let you use one monitor on three computers and many more other specialized options.
Software switches
So far we talked about Hardware switches, a real device being able to take peripherals into it and switch computers on the fly. On the other line, we have software switch solutions that will have specific software installed on all computers and have it run at all times, and switching between them will be through specific software.
There are two very good and main advantages of using software solutions instead of a hardware one. First, of course, is the price, since the most popular Synergy is an open-source solution, completely free of charge. The second big advantage is that software switch is not limited to how many computers can you use. Hardware switches tend to go to a large number like 16 but if you have a large cluster of computers over a LAN, let's say 30 then the box solution might be difficult.
On the other hand software solution will switch only keyboard and mouse since each other computer will have to have some screen on it in order to work. Both solutions have their strong advantages and disadvantages and it is up to you to choose one that best suits you.
Conclusion
If you are multitasking with a lot of computers or just need your peripherals from time to time to connect to another machine then the KVM switch is something that you might find the use of. Just be aware that if you go for some cheap switch you might experience some lag on your peripherals, but if that is not a concern you can get hardware one for as low as $50 USD.


Following a two-year investigation by the California Department of Fair Employment and Housing, the state has filed a lawsuit against Activision Blizzard for fostering a "frat boy" culture in which female employees are allegedly subjected to unequal pay and sexual harassment.
As reported by Bloomberg, Activision Blizzard is being accused by the state of California of discriminating against female employees at nearly all levels of employment, including in regards to compensation, promotion, assignments, and termination. The state alleges Activision Blizzard’s leadership has failed to address any of these outstanding issues or prevent them from occurring within the workplace. You can read the full details of the lawsuit here.
The suit, filed Tuesday in the Los Angeles Superior Court, says Activision Blizzard, which is made up of about 20 percent women, assigns women, and women of color, to "lower paid and lower opportunity levels" with lower starting pay for similar work as their male counterparts.
The documents also accuse Activision Blizzard of fostering a "pervasive 'frat boy' workplace culture in the office. Male employees are said to drink "copious amounts of alcohol" as they make their way through cubicles and "often engage in inappropriate behavior toward female employees."
Male employees are said to come to work hungover, play video games during work "while delegating their responsibilities to female employees, engage in banter about their sexual encounters, talk openly about female bodies, and joke about rape."
The lawsuit also cites one particular incident where a female employee, who was already subjected to intense sexual harassment at the company, committed suicide during a work trip with a male supervisor who allegedly brought inappropriate, sexual items with him on the trip.
The lawsuit is asking for an injunction that will force Activision Blizzard to comply with workplace protections, as well as deliver unpaid wages, pay adjustments, back pay, and lost wages and benefits for female employees.
