Network Operating System falls under the category of Distributed architectures where a large number of computer systems are connected with each other with the help of a network. Although the implementation of the network operating system is simpler than the distributed operating system. The network operating system and distributed operating system are distinguished by the characteristics they are having, such as the in network operating system each system runs its own operating system while the … [Read more...]

The Time Sharing and Real Time operating systems are the types of operating systems which can be differentiated in many ways. The time sharing operating system is used to perform general tasks while real-time operating system tends to have a very specific task. The significant difference between time sharing and the real-time operating system is that time sharing operating systems concentrates on the generation of the quick response to the subrequest. On the other hand, the real-time operating … [Read more...]

RAID (Redundant Array of Independent Disk) are the group of disk organisation techniques evolved to deal with the reliability and performance. The fundamental difference between the RAID 0 and RAID 1 is that the RAID level 0 does not contain redundant data, in fact, it uses striping. On the other hand, RAID level 1 uses mirroring and contain redundant data. The RAID was initially abbreviated as redundant disks of inexpensive disks because it was devised for providing large disk capacities at … [Read more...]

FAT32 and NTFS are the files systems used in an operating system. NTFS is the successor of the FAT32 which is used in newer versions of operating systems such as Windows NT and 2000 and its later versions while FAT32 is the oldest version of the file systems and used in earlier versions of the operating system such as DOS and Windows version before XP. The prior difference between FAT32 and NTFS is that NTFS file system can trace the changes committed in the system with the help of maintaining … [Read more...]

The operating system provides measures to prevent the interference with the utilization of logical and physical resources, which are known as security and protection. The security and protection are sometimes interchangeably used as they do not sound very distinctive. Although, the terms security and protection are majorly different. The main difference between security and protection lies within the fact that the security handles the external information threats in the computer systems whereas … [Read more...]

Most of us generally know what a ROM memory (Read Only Memory) is. It is so called "read-only" because it holds a persistent pattern of data that cannot be altered. The PROM, EPROM, EEPROM and flash are the types of ROM. In this article, we will understand the difference between PROM and EPROM specifically. So, the main difference between PROM and EPROM is that the PROM can be programmed just once means that it can be written only one time whereas EPROM is erasable; hence it can be reprogrammed … [Read more...]

Hard and Soft real-time systems are the variants of real-time systems where the hard real-time system is more restrictive relative to the soft real-time system. The hard real-time system must assure to finish the real-time task within the specified deadline while this is not the case in the soft real-time system, it assigns the superior scheduling priority to the real-time tasks. Real-time systems involve a set of applications where the operations are performed in a timely manner to govern … [Read more...]

A program and a process are related terms. The major difference between program and process is that program is a group of instructions to carry out a specified task whereas the process is a program in execution. While a process is an active entity, a program is considered to be a passive one. There exist a many-to-one relationship between process and program, which means one program can invoke multiple processes or in other words multiple processes can be a part of the same program. Content: … [Read more...]

SRAM and DRAM are the modes of integrated-circuit RAM where SRAM uses transistors and latches in construction while DRAM uses capacitors and transistors. These can be differentiated in many ways, such as SRAM is comparatively faster than DRAM; hence SRAM is used for cache memory while DRAM is used for main memory. RAM (Random Access Memory) is a kind of memory which needs constant power to retain the data in it, once the power supply is disrupted the data will be lost, that's why it is known … [Read more...]

RPC and RMI are the mechanisms which enable a client to invoke the procedure or method from the server through establishing communication between client and server. The common difference between RPC and RMI is that RPC only supports procedural programming whereas RMI supports object-oriented programming. Another major difference between the two is that the parameters passed to remote procedures call consist of ordinary data structures. On the other hand, the parameters passed to remote method … [Read more...]
