An Optimist's View of the 4 Challenges to Quantum Computing by Jim Clarke. IEEE Spectrum, March 22, 2019. The promise of quantum computers is too great to abandon the effort in the face of technical challenges, argues Intel's director of quantum hardware. Computer input is called data and the output obtained after processing it, based on user’s instructions is called information. Raw facts and figures which can be processed using arithmetic and logical operations to obtain information are called data. Algorithms for quantum computation: discrete logarithms and factoring by Peter Shor, Proceedings 35th Annual Symposium on Foundations of Computer Science, 1994, pp.124–134.

Once you understand that computers are about input, memory, processing, and output, all the junk on your desk makes a lot more sense:

You need to perform some basic maintenance on your computer to keep it running in top shape. Here’s some advice to keep your computer secure and performing optimally: We have decades of experience building ordinary, transistor-based computers with conventional architectures; Control Unit− As the name suggests, this unit controls all the functions of the computer. All devices or parts of computer interact through the control unit.

What is quantum computing?

exactly. Apart from Shor's algorithm, and a search method called Grover's algorithm, hardly any other algorithms have been discovered that would quantum dots, which are nanoscopically tiny particles of semiconductors inside which individual charge carriers, electrons and holes (missing electrons), can be controlled. Another method Output Unit− Devices like printer and visual display unit that are used to provide information to the user in desired format are called output unit.

Always use your best posture while you compute. Don’t slouch! Elevate your wrists. Don’t tilt your head too far down. Here’s a list of standard computer peripherals — items that attach to the PC console. Place an X in the box to indicate where each item is attached. This information can help you reconnect everything later, in case you ever need to move the computer or take it to the repair shop. Peripheral
