How can pc take input from hardware like keyboard or mouse? How can read this input?

The inputs are received from hardware using "interrupts" or IRQs. An interrupt is very similar to you receiving an "interrupt" (i.e. doorbell) when someone is at the door. The cables/ports relay these interrupts to the PC.\n\nCheck out some assembly language books/device driver books for details.

Many monitors have USB hubs in them. You should have the other type of connector somewhere and this plugs into your computer. Then the USB ports on the monitor are very useful for keyboards or mice (less wires from desk to PC).

i/o means "Input/Output" \n\nAn i/o device is one that can have input orr output as the name suggests with your machine.  Keyboards, mice, usb drives--all are axamples of input and output.\n\nIn this case, the error is telling you that there is a problem reading the i/o (input/output) device--the USB drive.\n\nSo, does the drive work with another computer?  Does that USB port work with outher devices?

You have a processor, some memory, and some input/output devices.  The processor fetches instructions in sequence from a memory location, and modifies its internal state based on them.  The instructions also may tell it to write data out to memory, or make a call to an I/O device.  Hard drives, printers, monitors, and keyboards are all I/O devices.

Across multiple keyboards and multiple OSs - on the same system? If it were windows I would suspect the keyboard settings or default input language were set oddly (control panel).\nIf regardless of OS or kbd, it would be odd. Hardware issue with the system? Tried USB kbd if different?

Yes, but you will require a piece of hardware: a video capture device.  These allow video input to the pc, and can be used over USB, FireWire, etc.\n\nYou should be able to pick one up on ebay for a few bucks (20-30 for an older model, 50-60 for something new).

What a really bad accident.  Try to hook up a USB or PS/2 keyboard and see if the keys respond to that.  You might need to go to a technician, but I don't even know if they can help.  In the worst case, you probably need to get any important data from the laptop's hard drive by removing it and hooking it up to a desktop.  Then reinstall everything from the BIOS on up.\n\nLesson to remember: always check how much battery power you have, or at least plug it into the wall if you're doing any installations or critical system tasks.

try coding ur own keyboard driver\n\nsuch that when A is pressed u translate it into a AB to the OS

Computer Mother board and its constituent components\n\n\n\n            1. Mouse & keyboard\n            2. USB\n            3. Parallel port\n            4. CPU Chip\n            5. RAM slots\n            6. Floppy controller\n            7. IDE controller\n            8. PCI slot\n            9. ISA slot\n            10. CMOS Battery\n            11. AGP slot\n            12. CPU slot\n            13. Power supply plug in\n\n1. Mouse & keyboard:  Keyboard Connectors are two types basically. All PCs have a Key board port connected directly to the motherboard. The oldest, but still quite common type, is a special DIN, and most PCs until recently retained this style connector. The AT-style keyboard connector is quickly disappearing, being replaced by the smaller mini DIN PS/2-style keyboard connector.\n                    You can use an AT-style keyboard with a PS/2-style socket (or the other way around) by using a converter. Although the AT connector is unique in PCs, the PS/2-style mini-DIN is also used in more modern PCs for the mouse. Fortunately , most PCs that use the mini-DIN for both the keyboard and mouse clearly mark each mini-DIN socket as to its correct use. Some keyboards have a USB connection, but these are fairly rare compared to the PS/2 connection keyboards.  \n\n2. USB (Universal serial bus): \n USB is the General-purpose connection for PC. You can find USB versions of many different devices, such as mice, keyboards, scanners, cameras, and even printers. a USB connector's distinctive rectangular shape makes it easily recognizable. \n        \n  USB has a number of features that makes it particularly popular on PCs. First, USB devices are hot swappable. You can insert or remove them without restarting your system.\n\n3. Parallel port: Most printers use a special connector called a parallel port. Parallel port carry data on more than one wire, as opposed to the serial port, which uses only one wire. Parallel ports use a 25-pin female DB connector. Parallel ports are directly supported by the motherboard through a direct connection or through a dangle.\n\n4. CPU Chip : The central processing unit, also called the microprocessor performs all the calculations that take place inside a pc. CPUs come in Variety of shapes and sizes.\n    Modern CPUs generate a lot of heat and thus require a cooling fan or heat sink. The cooling device (such as a cooling fan) is removable, although some CPU manufactures sell the CPU with a fan permanently attached.\n\n5. RAM slots: Random-Access Memory (RAM) stores programs and data currently being used by the CPU. RAM is measured in units called bytes. RAM has been packaged in many different ways. The most current package is called a 168-pin DIMM (Dual Inline Memory module).    \n\n6. Floppy controller: The floppy drive connects to the computer via a 34-pin ribbon cable, which in turn connects to the motherboard. A floppy controller is one that is used to control the floppy drive.\n\n7. IDE controller: Industry standards define two common types of hard drives: EIDE and SCSI.  Majority of the PCs use EIDE drives. SCSI drives show up in high end PCs such as network servers or graphical workstations. The EIDE drive connects to the hard drive via a 2-inch-wide, 40-pin ribbon cable, which in turn connects to the motherboard. IDE controller is responsible for controlling the hard drive.\n\n8. PCI slot:  Intel introduced the Peripheral component interconnect bus protocol.  The PCI bus is used to connect I/O devices (such as NIC or RAID controllers) to the main logic of the computer. PCI bus has replaced the ISA bus.\n\n9. ISA slot:  (Industry Standard Architecture) It is the standard architecture of the Expansion bus. Motherboard may contain some slots to connect ISA compatible cards.\n\n10. CMOS Battery: To provide CMOS with the power when the computer is turned off all motherboards comes with a battery. These batteries mount on the motherboard in one of three ways: the obsolete external

if your computer is bluetooth enabled, get a bluetooth keyboard and mouse combo.  you can get it at a whole lot of places.

What device are you trying to interface with?  Generally devices that provide input to the computer do it in a specific way.  Bar Code readers (for example) provide input through the keyboard.  The computer is not aware of them ususally, and doesn't care that they are there.  \n\nYour question is too open ended.  Yes, it is possible ot interact with client side DLLs, but you have to know WHAT dll you're interacting with ahead of time, and there are some specific configuration things that have to be done.  \n\nPost some additional information that better defines your intent (what you are trying to do with this, what devices you want to interact with), and you can get a better answer.  Any device for any purpose....well, the answer to that is easily NO.

On wireless mice and keyboards there is a button on them that tells the adapter that the mice and keyboard are there. press it on each after restarting your computer. Check manuel for more detailed instructions.

An Input device is anything that sends data to the computer, I suppose...\n\nSo for example, Keyboard, Mouse, Joystick, Microphone, Scanner, Graphics tablet and digital camera. Just to name a few\n\nOutput devices are the opposite they get data out, eg monitor, speaker and a printer are some good examples

I am not sure?  I have no idea how old your computer is? but from past experience some Compaq use a USB keyboard only but you can also buy an adapter for about $2 that will plug into your I/O plug... this will make it possible to use just about any keyboard.... also if on the back of your computer next to your mouse plug there is another plug about twice as large as the mouse plug then you can also buy an adapter that will use the I/O type keyboard or the one with the small plug like the mouse plug.... Anyway most computer stores have the adapters for around $2 or a friendly computer shop will just give you one for free.... I am sure if you go to your local computer shop they will tell you what you need and give you the right adapter...

Easiest way is to use something called GOTOMYPC. If it's a one-off, use their trial.\n\nIt does give you complete access to the PC
