Network Operating Systems vs. MUOS (Multi-User) Characteristics Different methods of Multi-tasking Multi tasking is when the operating system seems to be performing two or more tasks at the same time‚ i.e. MS Word and MS Access‚ however these tasks are not actually running simultaneously as they are actually resident in memory processor is actually switching between tasks at a very high speed‚ therefore each user sees their own task as having priority. One disadvantage can be that the more

wireless sensor networks can be promptly understood simply by thinking about what they essentially are: a large number of small sensing self-powered nodes which gather information or detect special events and communicate in a wireless fashion‚ with the end goal of handing their processed data to a base station. Sensing‚ processing and communication are three key elements whose combination in one tiny device gives rise to a vast number of applications [A1]‚ [A2]. Sensor networks provide endless

Internet and layered protocol architecture: Q1. (5 points) In the layered protocol architecture the transport layer functionality includes congestion control and error recovery (e.g.‚ retransmission). One suggested that this functionality should be done strictly at the end points (i.e.‚ at the hosts) without aid from the network. Do you agree
