Why do we need mobile cloud computing?

Mobile cloud computing allows you to store and retrieve data from anywhere in the world through any device as long as it is connected to the internet. This allows the smooth exchange of data whenever there is a need for information.

What is are true about mobile cloud computing MCC?

According to the question the answer is option b) MCC reduces the running cost for computation intensive applications. The reason for this answer is, because in cloud computing a low performance computer can do a great performance if there is enough arrangements doe with cloud computing via internet.

What is the function of scheduler?

The scheduling activity is carried out by a process called scheduler. Schedulers are often designed so as to keep all computer resources busy (as in load balancing), allow multiple users to share system resources effectively, or to achieve a target quality-of-service.

What is Scheduler in cloud computing?

The concept of scheduling in cloud computing refers to the technique of mapping a set of jobs to a set of virtual machines (VMs) or allocating VMs to run on the available resources in order to fulfill users‘ demands [4].

What is VM scheduling?

Virtual Machine (VM) scheduling algorithms are used to schedule the VM requests to the Physical Machines. (PM) of the particular Data Center (DC) as per the requirement fulfilled with the requested resources.VM. Scheduling determines how many processing cores of a host are allocated to virtual machines and how many.
