Difference between GNU and Unix
Even though the majority of us are accustomed to using Windows as our primary operating system, it is important for us to at least be familiar with other operating systems such as Unix, Linux, and others. This does not imply that Windows is the only operating system that has been used globally; rather, it indicates that other systems also take a larger proportion in terms of utilisation. The end functionality, which is using the computers to make our tasks easier, is the same regardless of the operating system that we might choose.Read through this article to find out more about ...
Read MoreHow to Find Out File Types in Linux
When it comes to Linux operating system, everything in general can be considered as a file. In UNIX, in total, there are seven standard file types −FIFO specialBlock specialCharacter specialSocketRegularDirectorySymbolic linkWhen it comes to Files, these can be mainly categorized into the following categories −Regular FilesDirectory FilesSpecial FilesThe simplest way to find out what a particular file is in an operating system is by looking at what kind of extension that particular file has. The extensions can be '.txt', '.py', '.go', etc. If a particular file does not have any extension in Linux, then we basically call that file as ...
Read MoreHow to Repeat Your Last Command in Linux?
Linux terminal allows us to execute a variety of commands and sometimes it so happens that we find ourselves in a scenario where we might want to use a certain command more than once. There are many occurrences where we would want to repeat the command that we just ran. In Linux, this can be done with the help of different commands, and in this tutorial, we will explore all such commands with the help of different examples. For reference and simplicity, I will run a single command, say 'ls -ltr' and then use the different methods to search what ...
Read MoreHow to Run a Command Multiple Times in Linux?
There are scenarios where you would want to run a particular command for 'N' number of times. In normal programming, this can be done with the help of any of the loops constructs available in that programming language. In Linux bash too, we have loops available as some other ways with which we can repeat commands 'N' number of times. In this tutorial, we will explore different bash scripts that will allow us to run a certain command multiple times. The first step when you want to work with a bash script is to create one. On Linux or macOS ...
Read MoreArray Operations in Linux bash
Bash scripts are one of the most convenient approaches when we talk about making the command line processes automated in nature. They help us in doing a group of things in a simpler and more understandable manner, and we can do almost all theoperations that we could do in other languages as well.It is well known that the syntax of the bash can be tricky at first, and hence I will try to explain everything that I have used in this tutorial.We come across various situations where we would want to make use of bash scripts to perform different operations ...
Read MoreWhat languages have been used to write Windows, Mac OS and Linux OS?
We know that an operating system is considered the backbone of any system that you may use. The three most common and widely used operating systems share things in common just as well as they share differences. While there are cases where one might outperform another, those cases and such scenarios are very rare.The most notable difference one can notice is how they store the files in their file structure, like in case of windows, it follows a directory structure to store the different kinds of files of the user, whereas the Mac OS file structure is known as MAC ...
Read MoreWhich one is safer Sleep or Hibernate in Windows?
Users generally sleep, hibernate or shut down their PC/laptop without having any clue what exactly these different terms denote. Here, you get clarity for these terms.Sleep ModeIf you leave your device on sleep mode, it allows you to work resume your work at the cost of some electricity as it moves to the low power state. It is also known popularly as Standby. As soon as you turn your device on, the whole device will snap back to life instantly. The files you left open will be taken care of automatically.HibernatePutting your laptop/PC on hibernate mode is more or less ...
Read MoreWhat is LAN (Local Area Network) in Computer Network?
A local area network is a comparatively lesser and privately-owned network with the highest duration of 10km to support local connectivity within a building or limited geographical area.In private offices, this type of networking is trendy and effectively used. They are generally used to interface with personal computers and buildings, incorporate workplaces and industry to share resources and transfer data.The figure shows a LAN having computers from several departments like Sales, Finance, Production, Publication, etc.Features of LANLimited Geographic LimitsA LAN is constructed for a limited area. It usually traverses a single frequency workgroup floor in a building or on campus ...
Read MoreBeowulf Clusters
A beowulf cluster is formed using normal computers that are identical. These are arranged into a small local area network (LAN). There are programs that allow these computers to share processing among them.So beowulf clusters form a parallel processing unit using common personal computers.An image that displays the first beowulf cluster at Barcelona Supercomputing Center is as follows −Image Credit − By Vcarceler [CC BY-SA 3.0 (https://creativecommons.org/licenses/by-sa/3.0)], from Wikimedia CommonsFeatures of Beowulf ClustersSome important features of beowulf clusters are as follows −Beowulf clusters are formed using normal computers. There is no software that denoted a cluster as a beowulf cluster.A ...
Read MoreErasable Programmable Read Only Memory (EPROM)
The Erasable Programmable Read Only Memory is a memory chip that does not lose data even when the power is switched off. This is a non-volatile memory type i.e. it retains data even when the power is switched off. Each EPROM is individually programmed by an electronic device. After that, the data can be erased by exposing the EPROM to strong ultraviolet light.An EPROM contains a transparent fused quartz window at the top of the package which allows exposure to ultraviolet light. The silicon chip is visible from this window.EPROM OperationA single field effect transistor constitutes a storage location. This ...
