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...]

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...]

Concurrency and parallelism are related terms but not the same, and often misconceived as the similar terms. The crucial difference between concurrency and parallelism is that concurrency is about dealing with a lot of things at same time (gives the illusion of simultaneity) or handling concurrent events essentially hiding latency. On the contrary, parallelism is about doing a lot of things at the same time for increasing the speed. Parallelly executing processes must be concurrent unless … [Read more...]

User Interface is the term used for specifying how a user interacts with an electronic device, particularly computer. CLI and GUI are the different kinds of user interfaces. Mainly they differ in the graphics employed in the operating system. To perform an operation on the CLI system one has to write a command. On the other hand, in GUI users provided the visual aids (graphics) that include images and icons, which facilitates users to perform a task directly. CLI systems require expertise in … [Read more...]

The links in Unix are essentially the pointers which associate to the files and directories. The major difference between a hard link and soft link is that hard link is the direct reference to the file whereas soft link is the reference by name which means it points to a file by file name. Hard link links the files and directories in the same file system, but the Soft link can traverse file system boundaries. Before understanding links we should first understand inode, an inode is a data … [Read more...]

The prior difference between Linux and Windows operating system is that Linux is totally free of cost whereas windows is marketable operating system and is costly. An operating system is a program intended to control the computer hardware and behave as an intermediary between user and hardware. Linux is an open source operating system where users can access the source code and can improve the code using the system. On the other hand, in windows, users can not access source code, and it is a … [Read more...]
