First-In, First-Out (FIFO) scheduling is a straightforward algorithm where the first process to arrive in the ready queue is the first to be executed by the CPU. This approach is simple to implement and ensures that processes are handled in the order they arrive, promoting fairness. However, FIFO can lead to the "convoy effect," where shorter processes wait for a long process to complete, potentially causing inefficient CPU utilization and increased average waiting time. As a result, while FIFO is easy to understand, it may not be the best choice for systems requiring optimal performance.

A scheduler is the heart of every RTOS. It provides the algorithms to select the task for execution. Three common scheduling algorithms are > Cooperative scheduling > Round-robin scheduling > Preemptive scheduling RTOS uses preemptive (priority based) scheduling. In some cases, real-time requirements can be met by using static scheduling.

Some common strategies for solving the job scheduling problem efficiently include using algorithms such as greedy algorithms, dynamic programming, and heuristics. These methods help optimize the scheduling of tasks to minimize completion time and maximize resource utilization. Additionally, techniques like parallel processing and task prioritization can also improve efficiency in job scheduling.

Graph coloring is used in several algorithms, for example in scheduling algorithms. Whether you use that in your "daily life" or not depends on what area you work in.
Yes, it is one of many scheduling algorithms suitable for time sharing.However it is not suitable for scheduling in a hard realtime OS that must consistently meet deadlines.
There isn't a single "best" scheduling algorithm, as the effectiveness of a scheduling algorithm depends on the specific requirements and constraints of the system in question. Common algorithms include Round Robin, Shortest Job First, and Priority Scheduling, each with its strengths and weaknesses. For real-time systems, Rate Monotonic Scheduling may be preferred, while for batch processing, Shortest Job First could be more efficient. Ultimately, the best choice depends on factors such as system load, response time requirements, and resource availability.

Disk scheduling policies and algorithms are used to manage how requests for disk access are processed. Common algorithms include First-Come, First-Served (FCFS), Shortest Seek Time First (SSTF), SCAN, and C-SCAN. FCFS processes requests in the order they arrive, while SSTF selects the request closest to the current head position to minimize seek time. SCAN and C-SCAN move the disk arm in one direction servicing requests until the end is reached, then reverse direction (SCAN) or jump back to the beginning (C-SCAN).
This refers to Round Robin scheduling, a method implemented in various situations that require scheduling algorithms e.g in memory management within a CPU. If for example you have 5 processes loaded in memory, RR scheduling would allocate an even number of time quanta from the processor to each process in turn, returning back to the first process and continuing as new processes are added and old ones are completed.
