Explain briefly about, processor, assembler, compiler, loader, linker and the functions executed by them?
Processor:--A processor is the part a computer system that executes instructions .It is also called a CPU Assembler: -- An assembler is a program that takes basic computer instructions and converts
A real time process is a process that must respond to the events within a certain time period. A real time operating system is an operating system that can run real time processes successfully
Latest Answer : RTS like embedded system work in real time, like robort work on RTS. Windows CE is RTOS. ...
A hard real-time system guarantees that critical tasks complete on time. This goal requires that all delays in the system be bounded from the retrieval of the stored data to the time that it takes the
A real time operating system has well defined fixed time constraints. Process must be done within the defined constraints or the system will fail. An example is the operating system for a flight control
Hard disk is the secondary storage device, which holds the data in bulk, and it holds the data on the magnetic medium of the disk.Hard disks have a hard platter that holds the magnetic medium, the magnetic
A virtual memory is hardware technique where the system appears to have more memory that it actually does. This is done by time-sharing, the physical memory and storage parts of the memory one disk when
Latest Answer : Virtual memory is a non physical (intangible) memory created by the CPU to temporarily store the data for displaying purpose. Example: the website page you are seeing is not stored in physical memory it is stored in virtual memory and when you close the ...
What are the difference phases of software development or software life cycle?Ans Specification of the taskDesign of algorithmsImplementation (coding)Testing and debuggingMaintenance and evolution of the systemObsolescence
Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. As the microprocessor processes data, it looks first in the cache memory
Latest Answer : A Cache is a fast memory (generally SRAMS) that is genearally installed between the main memory and disk to reduce the transfer rate and access time disparities. ...
An interpreter reads one instruction at a time and carries out the actions implied by that instruction. It does not perform any translation. But a compiler translates the entire instructions.
Describe different job scheduling in operating systems?
Scheduling is the activity of the deciding when process will receive the resources they request.FCFS: --- FCSFS stands for First Come First Served. In FCFS the job that has been waiting the longest is
