 Related Questions 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 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 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 ... 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. ... Paging is solution to external fragmentation problem which is to permit the logical address space of a process to be noncontiguous, thus allowing a process to be allocating physical memory wherever the A microcontroller is by definition a is a computer on a chip. It includes all the necessary parts (including the memory) all in one IC. You just need to apply the power (and possibly clock signal) to Latest Answer : hello sir, i am expect more details about microprocessor, because you was explained more briefly about microcontroller only. ... Switching the CPU to another process requires saving the state of the old process and loading the saved state for the new process. This task is known as a context switch.Context-switch time is pure overhead, DRAM is the Hershey's chocolate of readable/writable memory: it's not the best, but it's cheap, does the job, and is available almost everywhere you look. DRAM data resides in a cell made Latest Answer : DRAM forms the Physical Memory of the PC. The process of recharging described in the earlier post is know as a Refreshing Cycle. ... Distribute the computation among several physical processors.Loosely coupled system – each processor has its own local memory; processors communicate with one another through various communications Latest Answer : Distributed system in genral refers to n/w o.s in which various systems (computers) are connected to sharing some of resources like printer etc. Each system have own data (including files etc) and whenever access over other's system data is required FTP ... Main memory: – only large storage media that the CPU can access directly.Secondary storage: – extension of main memory that provides large nonvolatile storage capacity. Latest Answer : Primary is were the operating system and other files are stored which is usually the hard drive. Secondary is a second hard drive or a CD/DVD ROM or 3 1/4 inch floppy drive or any other type of device that stores data. * Primary storage is usually ...
