In Java private methods are the methods having private access modifier and are restricted to be access in the defining class only and are not visible in their child class due to which are not eligible for overridden. However, we can define a method with the same name in the child class and could access in parent class.Like private methods final methods in Java are the methods having final non-access modifier instead of private and are again restricted to be accessed in the defining class only and are not visible in their child class due to which are not eligible ...

During the execution of a program, the control unit fetches one instruction at a time from the main memory and then executes it. In this execution process, it takes help of ALU, if the instruction execution involves arithmetic or logical operation (like AND, OR, Ex-OR). After execution of the current instruction, the CPU fetches the next instruction for execution. This process continues until the program is completed and the result is output using the output device. In many computers, the control unit and the ALU are integrated into a single block, known as Central Processing Unit (CPU).Central Processing Unit (CPU) consists ... Read More
CPU and the main memory are having speed faster compared to the electromechanical input or output devices like printers, mouse etc. In such a case it is essential that the data lines of the computer should not kept engaged for a long time during communication with input/output (I/O) devices. Otherwise as an effect, the overall speed of the computer system comes down drastically. So I/O devices are connected to a computer through I/O ports.For example, to get a document printed by the printer, phase wise printer will get required information from the CPU to carry out the printing process. After ... Read More
A microcomputer can be defined as a small sized, inexpensive, and limited capability computer. It has the same architectural block structure that is present in a computer. Present-day microcomputers are having smaller sizes. Nowadays, they are of the size of a notebook. But in coming days also their sizes will get more reduced as well. Due to their lower costs, individuals can possess them as their personal computers. Because of mass production they are becoming still cheaper. Initially in the earlier days they were not very much powerful. Their internal operations and instructions were very much limited and restricted. But ... Read More
