1. A total of about 1 million bytes can be directly accessed by 8086 microprocessor.
2. The 8086 has thirteen 16 bit registers.
3. The 8086 has eight flags.
4. Compared to 8086, the 80286 provides a higher degree of memory protection.

Assertion (A): FET has characteristics very similar to that of pentode.

Reason (R): Both FET and pentode are voltage controlled devices.

Assertion (A): The function δ'(t - b) is equal to 0 for t ≠ b

Reason (R): A number of impulses spaced from one another form an impulse train.

1. N type semiconductor with work function φ_s more than work function φ_M of metal
2. N type semiconductor with work function φ_s less than work function φ_M of metal
3. P type semiconductor with work function φ_s more than work function φ_M of metal
4. P type semiconductor with work function φ_s less than work function φ_M of metal.

Assertion (A): Oxide coated cathodes are very commonly used.

Reason (R): Work function of oxide coated cathode is 1 eV whereas it is 4.5 eV for pure tungsten.

Assertion (A): The amount of photoelectric emission depends on the intensity of incident light.

Reason (R): Photo electric emission can occur only if frequency of incident light is less than threshold frequency.
