Timeline of Computer History [2]

Sony introduces the first 3 ½-inch floppy drives and diskettes in 1981. The first significant company to adopt the 3 ½-inch floppy for general use was Hewlett-Packard in 1982, an event which was critical in establishing momentum for the format and which helped it prevail over the other contenders for the microfloppy standard, including 3-inch, 3 ¼-inch, and 3.9-inch formats.
The machine was expandable, with ports for cassette storage, serial interface and rudimentary networking. A large amount of software was created for the “BBC Micro,” including educational, productivity, and game programs.
Apollo and its main competitor, Sun Microsystems, optimized their machines to run the computer-intensive graphics programs common in engineering and scientific applications. Apollo was a leading innovator in the workstation field for more than a decade, and was acquired by Hewlett-Packard in 1989.

Commonly Used Operating System [3]

There are various types of Operating Systems used throughout the world and this depends mainly on the type of operations performed. These Operating Systems are manufactured by large multinational companies like Microsoft, Apple, etc
Generally referred to as Microsoft Windows, these OS are manufactured and developed by the tech-giant Microsoft and are the most commonly used OS for personal computers and to some extent in mobile phones or the Windows phone. Microsoft Windows is a collection of many graphics-oriented operating systems, first developed and launched in 1985 by the name Windows 1.0
Slowly with the implementation of innovative features, the OS gained popularity and soon dominated the market of the Computer Industry, owing to its freedom of use and user-friendly environment. Let’s look at the advantages and disadvantages of using Microsoft Windows.

Windows vs MacOS vs Linux – Operating System Handbook [7]

Hi everyone! In this handbook I’m going to give a brief introduction to operating systems and compare the three main OSs that are out there nowadays.. First we’re going to review what an OS is and little history about them
The idea here is to explore their history, how and by whom they were developed, their business models, and their pros and cons. This will give you a better idea of how they work and which one to choose.
So keep in mind some of the things I mention here will be based on my own experience and analysis of the topic.. I’ll also provide a lot of additional articles/videos you can take a look at in case you’d like to dive into a particular subject.

What is a Network Operating System? [8]

A network operating system (NOS) is a computer operating system (OS) that’s designed primarily to support workstations, PCs and, in some instances, older terminals that are connected on a local area network (LAN). The software behind a NOS enables multiple devices within a network to communicate and share resources with each other
A NOS coordinates the activities of multiple computers across a network. This can include such devices as PCs, printers, file servers and databases connected to a local network
There are two basic types of network operating systems:. – Peer-to-peer (P2P) network OSes let users share network resources saved in a common, accessible location

Five Common Operating Systems [9]

Whether it’s a desktop or laptop computer, a smartphone or a video game system, every modern computer needs an operating system. That’s the core software on the computer that sits between application software and the hardware, distributing memory and computing resources to apps, managing files and enforcing security rules.
Operating systems define how a computer stores files, switches between different applications, manages memory, keeps itself secure, and interacts with peripherals like printers and cameras. Different operating systems take different approaches to all of these, which is why you normally can’t run a Windows program on a Macintosh computer and why permissions look different on an Android phone than on an iPhone.
Different operating systems run on different types of hardware and are designed for different types of applications. For example, iOS is designed for iPhones and iPad tablets, while Mac desktops and laptops use macOS

Operating system and user interface [10]

As already mentioned, in addition to the hardware, a computer also needs a set of programs—an operating system—to control the devices. – There are different kinds of operating systems: such as Windows, Linux and Mac OS
– Operating systems can be used with different user interfaces (UI): text user interfaces (TUI) and graphical user interfaces (GUI) as examples. – Graphical user interfaces have many similarities in different operating systems: such as the start menu, desktop etc.
An operating system (OS) is a set of programs which ensures the interoperability of the hardware and software in your computer. – the identification and activation of devices connected to the computer,

5 Most Popular Operating Systems [11]

You’ve probably been involved in a “PC versus Mac” argument at some point in your life. Everyone seems to have very strong opinions on the subject, but what it really comes down to is personal preference in operating systems.
They may say they like a particular command prompt, or they enjoy some pre-installed software, the look and feel of the hardware, the applications or systems they can download, or even the pre-installed web browser. But the reality is that the features of an OS aren’t immediately clear to most users
Students (particularly online students), freelancers, contractors, and anyone who owns a phone, computer, or tablet should learn about different OSs so they can pick a computer and OS that meet their needs. If you’re planning to study IT in school and pursue an IT career, you’ll want a strong knowledge of OSs to make sure you’re prepared for all the skills you’ll need to be successful in your field.

Information Literacy [12]

A personal computer is a general-purpose computer whose size, capabilities and original sale price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer operator. This contrasts with the batch processing or time-sharing models that allowed larger, more expensive minicomputer and mainframe systems to be used by many people, usually at the same time
Software applications for most personal computers include, but are not limited to, word processing, spreadsheets, databases, web browsers and e-mail clients, digital media playback, games and myriad personal productivity and special-purpose software applications. Modern personal computers often have connections to the Internet, allowing access to the World Wide Web and a wide range of other resources
A personal computer may be a desktop computer or a laptop,netbook, tablet or a handheld PC.. Early computer owners usually had to write their own programs to do anything useful with the machines, which even did not include an operating system

5 Information Systems Software [14]

Computer hardware is virtually useless without computer software. Software is the programs that are needed to accomplish the input, processing, output, storage, and control activities of information systems.
Systems software are programs that manage the resources of the computer system and simplify applications programming. They include software such as the operating system, database management systems, networking software, translators, and software utilities.
They include Aoff-the-shelf@ software such as word processing and spreadsheet packages, as well as internally or externally developed software that is designed to meet the specific needs of an organization.. Software trends have been away from custom-designed one-of-kind programs developed by the professional programmers or end users of an organization toward the use of Aoff-the-shelf@ software packages acquired by end users from software vendors.

Computer Hardware Software [15]

“an electronic device capable of receiving data, and performing a series of operations in accordance with predetermined procedural instructions or programmes to produce a result in the form of information or signals.”. Whilst completely different entities both physically and in functionality, computer hardware and computer software are entirely dependent on one another for them to have any sort of use.
Hardware encompasses the external tools that allow users to operate a computer, such as the keyboard and mouse, outer elements of the machine such as the monitor and tower, and internal components like the motherboard, graphics card, and data storage.. Computer software is the term used to define the sets of code, data, and instructions stored on the computer’s hard drive that operate the machine from behind the scenes
Application software gives functionality to an app, which will then run on operating software within a computer.. An operating system is a type of software that manages the hardware and software components of a computer system, all programmes, excluding firmware, require an operating system in order to function

Windows, macOS, Chrome OS, or Linux: Which Operating System Is Best? [20]

You don’t have a great many choices when it comes to your computer’s operating system, but the choice you make can have wide-ranging consequences. The five OSes included here are your most viable options: Windows 10, Windows 11, macOS Ventura, Ubuntu, and Google Chrome OS
Four come from commercial tech giants, while one, the Linux-based Ubuntu, is free and open-source. Windows and macOS are generally the most capable in terms of hardware, software, interface, and utilities, while Chrome OS is more lightweight and runs on inexpensive computers.
For example, you can run Windows on a Mac inside a virtual machine or dual-boot using Boot Camp (if you have an Intel-based Mac). You can also create a Linux partition on a Windows PC and boot to that when the need arises

Operating Systems [21]

Note that we said that an operating system is a set of programs. The most important program in the operating system, the program that manages the operating system, is the supervisor program, most of which remains in memory and is thus referred to as resident
An operating system has three main functions: (1) manage the computer’s resources, such as the central processing unit, memory, disk drives, and printers, (2) establish a user interface, and (3) execute and provide services for applications software. Keep in mind, however, that much of the work of an operating system is hidden from the user; many necessary tasks are performed behind the scenes
Furthermore, all input and output operations, although invoked by an applications program, are actually carried out by the operating system. Although much of the operating system functions are hidden from view, you will know when you are using an applications software package, and this requires that you invoke-call into action-the operating system
