  1. 3. refers to the frequency at which a chip like a CPU, one core of a multicore processor, is running and it is used as the indicator of the speed of the processor.
  2. 8. abbreviation for gigahertz, it’s a unit of alternating current equal to one thousand million hertz, the GHz is used as an indicator of the frequency of the UHF.
  3. 10. Data stored in ROM can only be modified slowly, with difficulty, or not at all, so it is mainly used to store firmware
  4. 11. is a component of a computer’s CPU that directs the operation of the processor.
  5. 12. is the electronic circuitry that the computer has the computer that carries the instructions of a computer program, when is performing the basic logical, arithmetic, control and input/output operations that are specified by the instructions.
  6. 13. Also called Random Access Memory is the place in a computing device where the operating system, application programs and data is current use are kept so they can be quickly reached by the device’s processor.
  7. 15. is a combinational digital electronic circuit, that performs arithmetic and bitwise logical operations on integer binary numbers.

  1. 1. is any continuous signal for which the time varying feature (variable) of the signal is a representation of some other time varying quantity, i.e., analogous to another time varying signal.
  2. 2. Since zeros and ones can be easily represented by two voltages, the binary system is the foundation on which digital technology is built. Every digital computer whether a pocket calculator or a mainframe uses the same binary notation.
  3. 4. CMOS simply describes the type of material from which this special memory is made.
  4. 5. A digital signal is a physical quantity that alternates between a discrete set of waveforms.
  5. 6. Also called CPU memory is an access memory RAM. That a computer microprocessor can access more quickly than it can access regular RAM, this memory is integrated directly in the CPU chip.
  6. 7. also called chip or microchip, is a set of electronic circuits on one little plate of semiconductor material, normally this material is silicon.
  7. 9. unit of frequency in the International System of Units and is defined as one cycle per second.
  8. 14. It’s the abbreviation for megahertz, one MHz represents one million cycles per second, the speed of microprocessors (clock speed) is measured in megahertz.
