In OSI 7 layer model, a header, or possibly a trailer, can be added to the data unit at each layerI 7 layer, but we will define a simple virtual packet which contains only 8bit data value without any header and trailer
Each packet contains one pixel information of the lenna256 image. We defined the 3 structures in "CPacketStruct.h" to express a packet as bit stream. Left structure is defined for bit stream for error detection code and right structure is defined for bit stream for error correction code. There is additional bit stream without any code, and the data structure of bit stream with no code is same as the Packet structure in "CPacketStruct.h"
typedef struct {
BIT dat1[5];
BIT dat2[5];
} EDBitStream;
BIT dat1[7];
BIT dat2[7];
} ECBitStream;
Fig. Bit stream structure
One pixel data is represented with 8 digits, and each 4 digits are divided into dat1, and dat2. In bit streams for error detection
Ex) 1 Pixel data = 100010012
Normal Packet
(Packet is not encoded)
Encoded Packet by Parity Bit
Encoded Packet by hamming code
[1000 1001]
[Pixel Data ]
[10001 10010 ]
[ (1000)+Parity || (1001) +Parity ]
[1101000 0111001 ]
[ (1000)* G || (1001) * G ]

In the following section, we shall discuss the algorithms for solving the matrix multiplication difficulty using the parallel models. Matrix Multiplication Problem Let ther
Q. Explain about Multiplicative Decrease ? Multiplicative Decrease (MD) if a time-out take places the threshold is set to one maximum segment size (TCP Tahoe, TCP Reno).
Use Packet Tracer software to model the network that you have designed, and configure the network to make sure it is running properly. The following requirements should be met:
a) A host is sending a HTTP request to a HTTP server. In the table below, propose a correct set of source and destination port numbers for segments sent from host to server and fr
What are the five major technologies that can be used to create Client/Server applications? Database Servers Groupware TP Monitors Distributed Objects Intranets.
Q. Show the CRC-Performance ? CRC-Performance CRC is able to detect all burst errors that affect an odd number of bits CRC is able to detect all burst errors of
Session layer protocols consists of NFS, SQL, RPC, Appletalk Session Protocol (ASP), XWindows, and NetBEUI.
Single company or organization owns this. They are usually LAN technologies. There can be multiple LANs in a campus or building linked together. They are sometimes known Intranet.
