MCN i.e Modern Computer Network is one of the core subject in Computer Engineering. This repo will have all the programs implemented my portraying various concepts in the course.

MCN : Modern Computer Network

• You will find this repository filled with programs that portray various concepts in the above mentioned subject.

Language : C++, JAVA

Exp 01: Devices used in netorking

• Study of various netwroking devices and their significance.

Exp 02: IP commands

• Study of various netwroking IP Commands and their significance.

Error Detection Codes

Exp 3: Cyclic Redundancy Check (CRC)

• It deals with CodeWord formation from sender side which is then sent to receiver.
• Receiver on receiving the data [ which is CodeWord ] validates it.
• If invalid sender shall resend the data otherwise sender can proceed with next set of data.

Exp 4: Checksum

• First data to be sent is divided into blocks of equal size
• This blocks are added and the sum formed is complemented forming checksum
• This checksum is appended to the data to be sent and sent receiver
• Receiver on receiving the data [ which has checksum ] validates it.
• It adds up all the blocks and complements the sum
• If result of complemented sum is 0 then No Error Otherwise Error.

Exp 5: Socket Programming

• To create a SOCKET for two way and one way communication between server and client.

Exp 6: Knowing IP addresses

• Includes IP addressing fundamentals, classful IP addressing, CIDR and subnetting.

Exp 7: Using The Cisco Packet Tracer

• In this experment we use Cisco packet tracer to form network topologies using switch and then router.
• Packet tracer was used effectively to send packet from one network to other using the router.
