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 ...
Micro-Kernel: A micro-kernel is a minimal operating system that performs only the essential functions of an operating system. All other operating system functions are performed by system processes. Monolithic:
Latest Answer : A monolithic kernel has all OS services running within the privileged mode of processor.It has only one address space i.e. kernel space. A micro-kernel uses the CPUs privileged mode only for really core sevices (task scheduling, interprocess communication ...
Multi programming: Multiprogramming is the technique of running several programs at a time using timesharing.It allows a computer to do several things at the same time. Multiprogramming creates logical
Latest Answer : yeah its precise...but can u throw more light on the differences between multiprogramming and multi tasking??thanks in advance ...
Semiconductor memories are of two types: RAM (random access memory) and ROM (read only memory).RAM is a read/write memory. Information can be written into and read from a RAM. It is volatile memory.It
Latest Answer : RAM Random access memory .It is a temporory memory . Here we can read and write the contentsROM -Read only memory .Here we canonly read the contents.We cannot modify the contents present in it. ...
Starvation: Starvation is a resource management problem where a process does not get the resources it needs for a long time because the resources are being allocated to other processes. Aging: Aging
Hard real-time systems – required to complete a critical task within a guaranteed amount of time.Soft real-time computing – requires that critical processes receive priority over less fortunate
