Microelectronics today encompasses thin-film, thick-film, hybrid, and integrated circuit 1________________. These approaches (and combinations of them) are being applied in 2____________ branch of electronics.
Integrated circuits that combine all the 3__________________ of a complete electronic circuit on a single chip of silicon can be produced. The implications of this in the microelectronic evolution are easily 4_______________. Let us compare a conventional J/K flip-flop circuit incorporating solid-state discrete devices and the same type of circuit employing integrated circuitry.

Thermionic emission is the most 1_______________and one most commonly used in electron tubes. In this method 2________________ is heated, resulting in increased thermal or kinetic energy of the unbound electrons. Thus, a greater number of electrons will attain sufficient speed and energy 3________________  from the surface of the emitter. The number of electrons released per unit area of an emitting surface is related to the absolute temperature
of the cathode and a quantity of the work 4_______________must perform when escaping from the emitting surface.

There are 1_______________ power amplifiers. These are similar to voltage amplifiers, except that their main 2__________________ is to supply a considerable amount of 3________________ i. e. voltage times current to the output or load circuit, although the ac input signal may not draw any grid current and, hence, the 4________________ power may be zero.

MS-DOS is an operating system - a piece of software which looks after the running of your computer. It lets you create and keep track of files, run and link programs, and make use of peripheral devices (for example, printers and disk drives) attached to your computer.
Because your computer can run with one of several different operating systems (for example, MS-DOS, CP/M) the operating system is not built into the computer. Instead it is loaded from disk when the computer is started up.
Once the operating system has been loaded into the computer’s memory the disk from which it was loaded may be removed if required. The operating system needs to be reloaded only if part has been overwritten (when using very large programs, for example) or when the computer is restarted.

Can your computer run with many different operating systems?
