Development of Autonomous Cars: Research and development have been made in enhancing the technology to create autonomous cars. All major automakers are making investigation for testing their own vehicle with self-driving cars. Google has done a brilliant research in self–driving cars. They have already driven hundreds of thousands of miles without or little human intervention. Transporting with autonomous vehicle reduces the driving time and drastically reduces accidents and also concentrates on safety measures. The person will set the destination and the cars software will sense the route and starts the car towards the sensed route. A variety of techniques is implemented to detect the surroundings. A sensor is placed on the left rear wheel to monitor the sideways movement. Radar system is placed in the front and rear bumpers to sense the obstacles and their distance. It reduces the mobility, safety, customer satisfaction and reduces crime.

Consider a system that uses a fixed-partition scheme, with equal partitions of size 2" bytes, and the main memory has 2¹8 bytes. A process table is maintained with a pointer to the resident partition for each resident process. How many bits are required for the pointer in the process table? Show all your steps.

Use the same semaphore notation shown above to describe how we can ensure the execution order of the following process execution graph: P6 P2 P7 P1 P3 P4 P5 Use all of the following semaphores in your answer: s1=0; s2=0; s3=0; s4=0; s5=0; s6=0;
