Q.1 Write short note on Thick
Ethernet and Thin Ethernet. [5+5]
Answer :
Thick Ethernet :
Thick
ethernet is Also known as 10 base 5 or thicknet. 10BASE5 was the original
commercially available variant of Ethernet. For its physical layer it used
cable similar to RG-8/U coaxial cable but with extra braided shielding. 10Base5
is nearly identical to 10Base2, except that it uses a different type of cabling
and media connector. 10Base5 is known as ThickNet because it uses the RG-8
coaxial cable. It requires an external transceiver to attach to the network
interface card on
Q.2 Explain Simplex protocol of
data link protocols. 10
Answer :
he Simplex protocol is data link layer protocol for
transmission of frames over computer network. It is hypothetical protocol
designed for unidirectional data transmission over an ideal channel, i.e. a
channel through which transmission can never go wrong.
It is assumed that both the sender and the receiver are
always ready for data processing and both of them
Q.3 Explain One-bit Sliding Window
Protocol. 10
Answer :
One-bit Sliding Window
Protocol :
In
this protocol, the sliding window is an abstract concept that defines the range
of sequence numbers that is the concern of the sender and receiver. The sender
and the receiver need to deal with only part of the possible sequence numbers.
The range which is the concern of the sender is called the send sliding window;
the range that is the concern of the receiver is called the receive

Q.1 What is virtual circuit
networks? Describe different stages of virtual circuit. [4+6]
Answer :
A
virtual-circuit network is a cross between a circuit-switched network and a
datagram network. It has some characteristics of both.
·
As in a
circuit-switched network, there are setup and teardown phases in addition to
the data transfer phase.
·
Resources can be
allocated during the setup phase, as in a circuit-switched network, or on
demand, as in a

Q.2 Write short notes on: (i) Choke
packets (ii) Explicit Congestion Notification.
[5+5]
Answer :
Choke packets :
A
choke packet is used in network maintenance and quality management to inform a
specific node or transmitter that its transmitted traffic is creating
congestion over the network. This forces the node or transmitter to reduce its
output rate. Choke packets are used for congestion and flow control over a
network. The source node is addressed directly by the router, forcing it to
decrease its sending rate .The source node acknowledges this by reducing the
sending rate by some percentage. An
Q.3 What is Queuing? Explain FIFO
queuing. [3+7]
Answer :
Queuing :
Queuing
theory is the mathematical study of the congestion and delays of waiting in
line. Queuing theory (or "queueing theory") examines every component
of waiting in line to be served, including the arrival process, service
process, number of servers, number of system places, and the number of
customers—which might be people, data packets, cars, etc. As a branch of
operations research, queuing theory can help users make informed business
decisions on how to build efficient

Q.1 Write short description for
five segment registers of 8086 microprocessor.
[2x5]
Answer :
Five segment registers
of 8086 microprocessor :
The
BIU contains four 16-bit segment registers. These are: the extra segment (ES)
register, the code segment (CS) registers, the data segment (DS) registers, and
the stack segment (SS) registers. The upper bits of the starting address of
each of the segments are held by these segment registers. The part of the

Q.2 Write down the steps of
Instruction execution cycle and program interpretation cycle. [5+5]
Answer :
The
interpreter reads the source program and stores it in memory. During
interpretation, it reads a statement, determines its meaning and performs
actions which implement it. This includes computational and input-output
actions. Figure 2.3(a) shows the schematics of program interpretation. Fig
2.3(b) shows the schematic of the execution of a machine language program by
the CPU of a computer system. CPU uses Instruction Pointer (IP) to note the
address of the
Q.3 Write down the functions of
pass 1 and pass 2 of Macro processor.
[5+5]
Answer :
The
source program is read and is then transformed into another program from which
all macro definitions have been removed. And also all macro calls have also
been replaced with the corresponding macro bodies. The output of the macro
processor will be an assembly language program containing no macros. Like in
assemblers, the macro processor can also be designed in two passes. In the
first pass, all the macro definitions are saved and expanded. The macro body,
that is, text is processed in the second pass. The macro processor treats it,
as though it is the original program. The macro processor is system software.
It is actually a program, which is a part of the assembler program. The macro
processor is designed in passes. In the design of a macro processor, there are
two important functions to be considered. They

briefly different components of object module of a program. [2+8]
Answer :
Object
Module :
The
object module of a program contains all information necessary to relocate and
link the program with other programs. anguage translators process source code
and produce output in the form of object modules. These modules need to be
processed by the Linkage Editor to become
Q.2 Write short notes on : (i)
Character devices (ii) Block devices
[5+5]
Answer :
UNIX/Linux
OS distinguishes and classifies devices that are attached to the computer
devices into three fundamental device types. They are (i) Character devices
(ii) Block devices (iii) Network interfaces. The modules developed as a device
driver are usually implemented for one of these types of devices. Depending
upon the device types, the modules for device driver can be classified as (i)
Q.3 Write down any five benefits of
UPnP based devices. [2x5]

Benefits
of UPnP technology :
UPnP
is media and device independence. UPnP technology can run on any network
technology using any communications media including Radio Frequency (RF,
wireless), phone line, power line, IrDA, Ethernet, and IEEE 1394. The benefits
of UPnP based devices are as follows:
