Susana Garcia IT242 week 5 Checkpoint Switching According to the textbook the packet switching networks move data in separate‚ the small data blocks or packets. When the packets are received they are reassembled in a proper sequence to make up the message. These packets do not depend on any path or connection and can take as many paths as necessary; this process is to maintain data integrity depending on the traffic load. The packet switched networks are used in LAN networks. The circuit switched

CHECKPOINT: SIGNALS Explain the differences between data‚ voice‚ and video signals in 200 to 300 words. Include a description comparing the differences between a private branch exchange (PBX) and Voice over Internet protocol (VoIP). The three types of signals data‚ voice‚ and video. Besides the obvious differences between these three signals there is more to them. The first signal I will describe is the video signal. Like the name suggest a video signal transmits videos from one point

Introduction RSA Algorithms RSA stands for Rivest-Shamir-Adleman algorithm was invented on 1977 which is mostly used public-key cryptosystem. It was designed by Ron Rivest‚ Adi Shamir‚ and Leonard Adleman (Milanov 2009). This is the 1st crypto system which used two different keys to encrypt and decrypt the messages. In this cryptosystem it uses public key to encrypt and private key to decrypt the messages. Public key can be shared with everyone but the private key has to be with the person who
