Oh, dude, keyboards these days use serial communication. Like, back in the day, parallel keyboards were a thing, but now it's all about that serial connection. So, yeah, if you're talking about modern keyboards, they're serial.
Depends, is the device serial or parallel?
parallel
multiplexer can be used as parallel to serial converter.
Some key differences between a Serial and Parallel Adder are that a Serial Adder is slower, a Parallel adder is a combinational circuit and the time required for addition depends on the number of bits in a Serial, but not a Parallel. A Serial Adder is a sequential circuit while a Parallel is a combinational circuit.
RS-232 serial ports, Parallel ports, and PS2 mouse and keyboard ports. These days, all of these functions can be handled by Universal Serial Bus (USB ) connections.
Usually serial. Parallel is almost completely gone, and serial is getting replaced by USB.
Serial
how old is my baldwin keyboard serial number 91002/28
A "serial to parallel" converter converts a serial data connection to a parallel data connection. For example, in computer storage, there are controller chipsets that convert SATA (Serial ATA) to PATA (Parallel ATA, also called IDE or EIDE).
parallel
It is less costly to design ever faster serial lines than to create and build the necessary circuitry to keep faster parallel channels properly aligned. This is why Parallel ATA and Parallel SCSI have migrated to Serial ATA (SATA) and Serial SCSI (SAS).
the keyboard is connected to the computer because if you want to type on the computer then the key board has to be connected with the computer other whys you won't be able to type on the computer!!! Hope I Helped You!!!
