Explanation:
Interesting problem that can happen to coffee drinkers and slush lovers.
Most of the time, multiple sticking keys simultaneously appearing infer a recent (3 days to a week) spill of a sugary liquid on the keyboard.
If it is a built in laptop keyboard, read no further, confide in a repair shop because keys are not easy to open, and harder to put back.
If it is a USB (or PS2) keyboard, AND you are handy, AND you can lift the key tops (and put them back), you can detach keyboard from computer, then after removing key tops of the sticky keys, try cleaning with warm (to better disolve the sugar) water with a non-dripping cotton tip and dry with cotton swaps. Let dry for the next few days before plugging in again. Do NOT use solvents, and definitely NOT "contact cleaners".
The safest and suggested option is to replace the (detachable) keyboard with a compatible or similar one. If PS2 keyboards are hard to find, there are converter cables that plug into the PS2 sockets of the computer, and accept USB input (and reverse cables).
Answer:
None, drivers are hardware specific, if both devices share the same hadware manufacurer they tend to have the same drivers.
A driver is a software component that lets the operating system and a device communicate with each other. So asking for a difference in drivers is as asking the difference in hardware in both devices, though one tends to be more intergrated they are all the same in low level functions
Also drivers might not even communicate directly with the device but send a request. thats why some drivers can be written directly into an operating system.
Answer:
In binary signaling, Non Return to Zero (NRZ) is the technique in which zero voltage is represented by 0 bit while high voltage is represented by 1 until the voltage level change from high to low.
Explanation:
There are different techniques to encode the signal for transmission between transmitter and receiver. These techniques includes return to zero, non return to zero. In return to zero technique, the if the voltage is high the signal will become 1 for half of the time period and then after half time period it return to 0.
In NRZ the signal is 0 if the voltage level is zero. In case of high voltage of the signal the binary bit remains 1 until the next zero voltage level arrive in the signal until the end of the time period of bit.
