The same style of connector, in single or paired 4-, 6-, or 8-pin configurations, may be used for additional CPU power and graphics card power. Power delivery to these devices has increased in successive generations of PC components, as their higher signal sophistication and speed requirements have raised their electrical demands.
The earliest name was Keyboard Video Switch (KVS). [2] With the advent of the mouse, the Keyboard, Video and Mouse (KVM) switch became popular. The name was introduced by Remigius Shatas, the founder of Cybex (now Vertiv), a peripheral switch manufacturer, in 1995. [3] Some companies call their switches Keyboard, Video, Mouse and Peripheral (KVMP).

In computing, an expansion card (also called an expansion board, adapter card, peripheral card or accessory card) is a printed circuit board that can be inserted into an electrical connector, or expansion slot (also referred to as a bus slot) on a computer's motherboard (see also backplane) to add functionality to a computer system. Sometimes ...
NXP devices have a higher power set of electrical characteristics than SMBus 1.0. The main difference is the current sink capability with V OL = 0.4 V. SMBus low power = 350 μA; SMBus high power = 4 mA; I²C-bus = 3 mA; SMBus ‘high power’ devices and I²C-bus devices will work together if the pull-up resistor is sized for 3 mA.
Another notable change is the replacement of the front-panel toggle switches and lights of a standard early-model S-100 system with a keypad and seven-segment LED display (early S-100 machines like the Altair or IMSAI 8080 contain no ROM and when they are started, the user "keys in" a program via the toggle switches to read a paper tape. Once ...

Without using moving parts, they are called solid state switches, which distinguishes them from mechanical switches. [ 1 ] Electronic switches are considered binary devices because they dramatically change the conductivity of a path in electrical circuit between two extremes when switching between their two states of on and off .
