Virtualization and Containerization are two techniques that allow users to host multiple applications on a single physical machine. Traditionally businesses used to run only one application on one physical machine. Like, a web server only runs websites, a database server runs a database, and an email server runs emails. This was the case with the earlier operating system, as they could not run multiple applications securely on a single server. Thus, to scale up the business, if a company … [Read more...]

Unix and Linux are the operating systems where Linux was derived from the early version of Unix. Although Linux is a derivative of Unix, they do differ on various points. The significant difference between the Unix and Linus operating systems is that Unix is a closed-source OS, whereas Linux is an open-source OS. Both Unix and Linux support multi-user, multiplatform, and multitasking. Still, they differ in terms of security, interface, use, error detection, and solution. In this section, we … [Read more...]

Static and dynamic memory allocation are the two ways of allocating memory to the computer program. The fundamental difference between these two kinds of memory allocation is that the static memory allocation allocates the memory when the programmer compiles the program. The dynamic memory allocation allocates the memory when the programmer executes the program. What is Memory Allocation? Memory allocation is the task of allocating the memory address to the program (instruction and data). … [Read more...]

Maskable and non-maskable interrupts are two kinds of interrupts in the CPU. The interrupt that can be ignored by the CPU is the maskable interrupt. The interrupt that cannot be ignored and is reserved for some important events is a non-maskable interrupt. What is Interrupt? An interrupt is a way to break the normal sequencing of the processor in order to perform some specific task. Let us understand interrupts in the operating system using a day to day example. Consider that you are … [Read more...]

System call and System program play an important role in the functioning of the operating system. As these constructs define what functions the operating system must perform. The system call creates an interface between the user program and the services of the operating system. On the other hand, the system program defines the user interface of the operating system. The system program also creates a suitable environment for a program to develop and execute. For example, the modern … [Read more...]

In a broad sense, Booting is a process of starting a computer and specifically handing over the control to the operating system. There are two forms of booting, Cold Booting and Warm Booting, here we are going to learn the difference between them. The notable difference between them is that the Cold Boot occurs at the beginning where the state of the primary components of the computer and RAM is checked with the help of Power On Self Test (POST) before loading the operating system. Conversely, … [Read more...]

We used to come up with the terms file and folder on a very frequent base, and these are the common terms in the computer field. A file in computer resembles a typed document that could be available on the someone's desk or inside a filing cabinet, practically. On the other hand, a folder is quite more than a container used to store files. It would not be practically possible to put several hundred or thousands of paper files on a desk, as when you need a particular file from those papers it … [Read more...]

DOS and windows are the different kinds of operating systems where the DOS is less likely used in the present scenario while windows is a widely used operating system. The operating systems, DOS and Windows are mainly differentiated by the fact that DOS is a single tasking, single user, CLI based operating system developed in the year of 1979. On the other hand, all the windows version are multitasking, multiuser and GUI based operating system. Content: DOS Vs Windows Comparison … [Read more...]

Multiprogramming and multitasking are the aspects of a computer system. However, these are also the types of operating system. The prior difference between multiprogramming and multitasking is that the multiprogramming is based on preemptive scheduling where the major pondering point is the CPU idleness. On the other hand, in the multitasking system, the CPU jobs have equal time interval for processing and it emphasis on responsiveness. The multiprogramming system is advantageous in terms of … [Read more...]

The CD and DVD are the versions of an optical disk which mainly differ in size and manufacturing method. Generally, a DVD can store more data than a CD, its one of the reason is that CD contain the polycarbonate substrate on only a single side while in DVDs it present on both of the sides. We have already discussed the construction and working principle of the optical disk in our previous article difference between Magnetic Disk and Optical disk. The CD and DVD work on optical technology … [Read more...]
