Answer:
8086 was
the first 16-bit microprocessor available in 40-pin DIP (Dual Inline Package)
chip. Let us now discuss in detail the pin configuration of a 8086
Microprocessor.

Answer:
A)
REP Prefix
Because string operations
inherently involve looping, the 8086 machine language includes a prefix that
considerably simplifies the use of string primitives with loops. This prefix
has the machine code

(b) IEEE 488 standard 5+5 10
Answer:
A) RS232 Standard
RS232 standard is developed by the Electronic Industry
Association (EIA) in 1962 and was revised and renamed as RS232C. RS stands for
"recommended standard." This is a standard hardware interface used
for implementing asynchronous serial data communication ports on devices such
as CRT terminals,

short note on:
a)
Parallel Printer Interface (LPT)
b)
Universal Serial Bus (USB) 5+5 10
Answer:
A)
Parallel Printer Interface
(LPT)
The parallel printer interface
(LPT) is located on the rear panel of the PC. The LPT stands for line printer.
The Parallel Port Interface on the PC compatible computer is one of the most
flexible interfaces for connecting the PC to a wide range of devices. The
interface was originally intended purely for connection to printers but due to
the simple nature of the digital control lines it has found many other uses.
Its simplicity relies on the fact that the data to and from the port forms an 8
bit binary on/off

Q1. Three machines A, B and
C produce respectively 60%, 30% and 10%
of the total number of items of a factory. The percentage of defective output
of these machines are respectively 2%, 3% and 4%. An item is selected at random
and is found to be defective. Find the probability that the item was produced
by machine C.
Solution: Let P(A), P(B) and P(C) denote the probabilities
of choosing an item produced by A, B, C respectively. Also, let P(X/A),
P(X/B), P(X/C) denote the probabilities of choosing a defective item from the
outputs of A, B, C respectively. Then, from what

Q.2 What are the different types of operators used in
Java? 10
Answer ;
Types of operators used in Java :
Operators are special symbols
(characters) that carry out operations on operands (variables and values). For
example, + is an operator that performs addition. In Java variables article,
you learned to declare variables and assign values to variables. Now, you will
learn to use operators to manipulate
Q.3 Differentiate between packages and Interfaces. 10
Answer:
Defining a Package :
To create a package is quite easy: simply include a package
command as the first statement in a Java source file. Any classes declared
within that file will belong to the specified package. The package statement
defines a name space in which classes are stored. If you omit the package
statement, the class names

Answer :
Components of an Event :
An event comprises of three components:
●
Event Object – When the user
interacts with the application by pressing a key or clicking a mouse button, an
event is generated. The operating system traps this event and the data
associated with it, for example, the time at which the event occurred, the
event type (like a keypress or a mouseclick). This data is then passed on to
the application to which the

Topological sort? And explain with example. 5+5=10
Answer: Topological sort is done using a
directed acyclic graph (DAG), which is a linear ordering of all vertices G= (V,
E) is an ordering of all vertices such that if G contains an edge (u, v), then
u appears before v in the ordering. A topological sort of a particular graph
