GENERATION (early 1960’s) The second generation of operating systems was characterized by the development of shared systems with multiprogramming and beginnings of multiprocessing. In multiprogramming systems several user programs are in main storage at once and the processor is switched rapidly between the jobs. In multiprocessing systems‚ several processors are used on a single computer system to increase the processing power of the machine. Device independence began to appear. In first generation

The highest level of parallel processing is conducted among multiple jobs or programs through multiprogramming‚ time-sharing‚ and multiprocessing. This presentation covers the basics of parallel computing. Beginning with a brief overview and some concepts and terminology associated with parallel computing‚ the topics of parallel memory architectures‚ Parallel computer architectures and

telegram was symmetric. The reason I believe that the message was considered symmetric is because in symmetric encryption a message is sent in cipher text and the person that is meant to receive the message has a code to convert the message from Cipher text to plain text. This is the method that Zimmermann used in his telegram. Zimmerman and the intended receiver of the message shared the key that decrypted the message from cipher text to plain text. Therefore the telegram used symmetric encryption
