An inverter is implemented with two different types of transistor

An inverter connects the output directly to either

the high or low power supply

An inverter is implemented with one transistor

CMOS stands for Complementary MOS. In this context, the

meaning of Complementary is

Signals are always complemented

The circuit contains both P-channel and N-channel transistors

Which of the following is NOT a correct statement about the oxide

layer in a MOS circuit?

The oxide layer prevents a short circuit between the substrate and the

gate in a transistor

The oxide layer conducts electrical current between neighboring transistors

The oxide layer is formed by exposing part of the substrate to oxygen,

converting it to silicon dioxide

Which of the following is NOT a correct statement about the metal

layer in a MOS circuit?

The metal layer provides wires for communicating signals between transistors

The metal layer is at the top of a transistor

The metal layer is directly connected to the semiconductor layer

The metal layer serves as the gate in a pass transistor

Most of the following statements about integrated circuits are

correct, but one is not. Which statement is NOT true?

An integrated circuit contains several layers

Transistors are constructed in a small area of an integrated circuit,

and are connected to other transistors by wires that are embedded in

the integrated circuit

Each transistor on an integrated circuit is manufactured individually,

one at a time

Wires that carry signals may be embedded in a substrate without a short

circuit because a short circuit would require a signal to cross a

reverse biased junction

Negative charge carriers are electrons

Which is NOT correct?

Positive charge carriers are positrons (the antimatter electron)

A hole is a position in a semiconductor which could hold an electron

but where the electron is not present

Electrical current can be carried by either negative or positive charge carriers

Jei vartojimo funkcija yra C = 150 + 0,85Y, o Y padidėja 1 vienetu, tai taupymas:

sumažėja 0,15 vieneto.

sumažėja 0,85 vieneto.

padidėja 0,85 vieneto.

padidėja 0,15 vieneto.

Which is NOT a characteristic of a semiconductor?

A semiconductor is made by doping silicon, so that some of the

atoms in the crystal have either one extra electron, or one fewer electron

Most electrons are tightly bound to atoms and not available as charge

carriers for electric current

A pure silicon crystal is a semiconductor

Some electrons are weakly bound to atoms, and can move through the

substance in the presence of an electric field

An advantage of using indentation to determine program structure is

If braces (or other punctuation) are used to determine the program structure,

there is a risk that the indentation could be inconsistent with the braces,

making the program hard to read.

If braces are used to determine program structure, the language is

ambiguous and the compiler cannot translate it

In the OrderedLists program (the program for the assessed exercise),

the high level algorithm for CmdDelete contains the following statement,

where q is a pointer to the node being deleted.

   ReleaseNode(q)

What would happen if this statement were omitted?

The node that q points to would remain in the list, and the

Delete command would have no effect

The node that q points to would be deleted from the list, but

at some time in the future a call to NewNode might fail with

an "Out of heap" error even though there is a node that could

be reused

The program would crash immediately
