Fundamentals of WAN

A collection of networks and/or local area networks (LAN) which communicate with each other is called a wide area network (WAN). A telecommunication network is extended over the geographical area for the basic computer network purpose (by connecting all smaller networks). From any part of the world, WAN allows communication and sharing the data between devices.

Process Scheduling: Select all statements below that are true The CPU burst is the amount of time a process obtains the services of a processor as a whole. Arbitration becomes necessary when two processes with equal priority are to be scheduled. Since resource sharing is the main focus of multi-programming, it essential to allow the scheduler to remove (pre-empt) processes from the CPU in response to changing circumstances. 0 When preemptive scheduling is applied, a process is allocated the CPU until it releases it again. The service time is also known as the turnaround time. The short-term scheduler selects which of the ready, in-memory processes is to be executed next.

Can someone please help and explain the C code that I would need for this. I am new to C and would like some help. I also do not know how to check the storage for the cache on my microsoft surface 2 computer. Define Data Structures Large Arrays: Define a large array in memory. The size should be chosen based on the cache size of the target processor. Choose a size that is larger than the L3 cache of the processor. You will need to look up the sizes of the L1, L2, and L3 for the processor you are using. Access Area: Access areas within the L1, L2, L3, and larger than the L3 cache. You must read memory the same number of times for each, but simply access more memory for each. Sequential Access: Access the elements of the first array sequentially. This pattern benefits from spatial locality, as once a cache line (containing a part of the array) is loaded into the cache, subsequent accesses to nearby elements will be faster. Random: Access the elements of the second array in a…
