2ND INTERNAL PREPARATION

identify the image

• master slave

• decoders

• nynon

• encoders

Answer explanation

An encoder can also be described as a combinational circuit that performs the inverse operation of a decoder. An encoder has a maximum of 2^n (or less) input lines and n output lines.

which is not a data transfer operation

• MOV/MOVI

• PUSH/POP

• LHLD

• STACK

Answer explanation

DATA OPERATION CONSISTS OF:

1. MOV

2. MOVI

3.XCHG

4.XTHL

5.PUSH

6.POP

7.LDA

8.LDAX

Find the 1's complement of 1011000011

octal to decimal conversions-> 630.4 (base 8)

Answer explanation

630.4 (base 8)

= 6* 8^2 + 3* 8^1 + 0*8^0 + 4 * 8^-1

=384 + 24 + 0 + 0.5

=408.5 (base 10)

Identify the binary value and convert it to octal-> 1101

• A

• D

• B

• C

What is the 4 cases doesn't match with the result in the binary form(add and sub) form

• error detection

• cyclic redundancy

• overflow

• fixed point representation

what is error detection and correction code?

• the addition of extra bits

• extra bit added to string of data

• character code

• it makes use of repetitive of each data bit in bit stream

Answer explanation

( PARITY CODE )-> extra bit added to string of data

( ALPHANUMBERIC CHARACTER CODES) -> character codes

( REPETITIVE CODE) -> it makes use of repetitive of each data bit in bit stream

which operand is PUSH Operation??

• register pair

• VMM

• 16-BIT Address

• NONE

operand of load accumulator's

• 12 bit

• registe pair

• 16 bit

• none

define byte
