Decode the location: 12011932256475,5786692130817, 36685018221928. Enter the decoding exponent: Enter the location (case sensitive):Assume you are one of the enthusiasts attempting to decipher the encoded message on the sculpture, and one of the lines on the sculpture is written: PSTEN OITNS ASCNO YRSOI EEIFO MRKIY YNTTM 3.4 Assuming that Sanborn used double columnar transposition with keys APPLE and FARAD when encrypting the message engraved on the sculpture. This message must be decrypted.
- Select the three true statements from the following list. Select one or more: O In cellular systems, frequency reuse exploits a phenomenon known as 'fading'. In CDMA, several messages can be sent simultaneously in the same cell only if they occupy different time slots. In GSM, under 75% of the bits in each TDMA frame are available for the message data. Live videoconferencing is much less sensitive to jitter than is the transmission of emails. The air interface for analogue mobile phones in the UK was FDMA. O In CDMA every bit in a message is replaced by a binary code word. In order for a mobile device that is moving around to receive an incoming call, its HLR works together with the VLR associated with the cell where the mobile device is currently situated.Suppose you are one of the hobbyists trying to decrypt the encoded message on the sculpture, and one of the lines on the sculpture is written: PSTEN OITNS ASCNO YRSOI EEIFO MRKIY YNTTM 2.1 Assuming it was recently learnt that Sanborn used double columnar transposition with keys APPLE and FARAD respectively when encrypting message inscribed on the sculpture. Decrypt this messageCharacter devices often send data quicker than block devices. Is this statement true or false? Explain your response.
