Explain three levels of data abstractions. Data abstraction is a process of recognizing the characteristics of an object or any situation and filtering out unwanted characteristic.
It is a process of getting arguments from the command prompt in C programming. There are three arguments in C main function. Argument counter, Argument vector, and environment vector. A cache is a small size computer memory that is used by CPU to reduce average cost to access data from main memory. In pass by value, we pass the value to calling function. In Pass by reference, we need to pass the address to the caller function instead of passing the value.
A null pointer is a pointer which points to nowhere. It has the value zero. Operator overloading is a polymorphism which allows existing operators to be redefined so that they can be used on objects of user-defined classes. A database should be normalized so that you can organize a database efficiently. You should also normalize a database to remove redundant data.
It is a software used to manage your database. DBMS provides an interface between application and databases. Conditional statements are also known as a conditional expression or if-then statement. Conditional statements are a set of rules.
These rules will be executed only if the condition is true. A foreign key is used to link to tables. On the other side, the reference key is a primary key that is referenced in the other table. An array is a data structure which contains similar elements. The necessary condition to use an array is that all array elements should have the same data type. Both are pointers to a constant Char.

Close Overlay. Swapping allows the CPU to do numerous jobs at the same time. As a result, procedures don't have to wait very long to be executed. It aids the CPU's ability to manage several tasks in a single main memory. It facilitates the creation and use of virtual memory. The RR round-robin scheduling algorithm was designed with time-sharing systems in mind.
The CPU scheduler goes around a circular queue, allocating CPU to each task for a time period of up to around 10 to milliseconds.
It is simple and easy to implement. It is preemptive because processes are only allotted CPU for a certain amount of time. All processes get an equal share of CPU. Disadvantages include context switches, low throughput, larger waiting time, and response time. An interrupt is a part of the hardware system that alerts the CPU when it wants to access a specific resource. Finding a suitable career necessitates a great deal of effort and focus.
