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.

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...]

Stack and Heap are the memory segments used in memory allocation techniques. The primary difference between Stack and heap is that stack involves linear and sequential allocation of the memory whereas heap acts as a pool of storage area which includes random allocation of the memory. Speed is the major parameter which distinguishes stack and heap; a stack is significantly faster than a heap. Content: Stack Vs Heap Comparison Chart Definition Key Differences … [Read more...]

The Process and Thread are the essentially associated. The process is an execution of a program whereas thread is an execution of a program driven by the environment of a process. Another major point which differentiates process and thread is that processes are isolated with each other whereas threads share memory or resources with each other. Content: Process Vs Thread Comparison Chart Definition Key Differences Conclusion Comparison Chart Definition of Process The … [Read more...]

We all are aware of ROM i.e. Read-Only Memory which contains the data required to boot up the computer system. It is a non-volatile memory, and it can not be modified easily or even sometimes not at all. But the modern ROM can be erased and reprogrammed in some way. Today we have modified version of ROM that are EPROM (Erasable Read-Only Memory) and EEPROM (Electrically Erasable Read-Only Memory). EPROM and EEPROM can be erased and reprogrammed again but at a very slow speed. Erasing requires … [Read more...]
