Windows is a graphical operating system that lets users view and store files. It also allows them to run applications and connect to the Internet. Microsoft has been releasing different versions of windows since 1985.
All window systems have some form of bit block transfer function (Blit in MS Windows, XCopyArea in X). This functions copy a rectangular area from one memory space to another.
Windows 1.0
This version of Windows was the first in Microsoft’s line of graphical operating systems. It runs as a 16-bit shell over MS-DOS and allows you to run graphical programs designed for Windows as well as existing MS-DOS software. It offers cooperative multitasking and features tiled windows.
When it first hit the market in November 1985, many of Microsoft’s rivals were already introducing desktop-style GUIs to their systems. Contemporary technology publications panned it for running too slowly on certain hardware, its awkward use of a mouse and other quirks.
Windows 1.0 also had a feature that allowed applications to overlap, but that was removed later on — possibly after a lawsuit from Apple.
Windows 2000
Also known as Win2k, Windows 2000 sped up performance on business servers by introducing memory and processor optimization techniques. It was also the first version of Windows to incorporate a system file protection mechanism that prevents the overwriting of operating system core files.
In addition, it offered advanced capabilities for supporting new hardware and peripherals. The system also allows users to customize the appearance of folders and files using HTML based appearance templates.
This release of the Windows NT family was primarily targeted for use on server computers in businesses as well as desktop machines in at-home environments. Its release was a significant milestone toward the far more stable and technically sophisticated, yet user-friendly, Windows operating systems we enjoy today.
Windows XP
Windows XP is the consumer version of the Windows operating system. It succeeded the NT-based Windows 2000 and 9x-based Windows Me.
It prioritised user needs, introduced a personal firewall and provided peer-to-peer networking support. It also included a new version of Internet Explorer and Outlook Express.
It requires a 233 MHz or higher Pentium processor, 64 MB of RAM and 1.5 gigabytes of hard drive space for its installation files. Typical settings will work for most users installing XP in a home or personal computer setting; however, check with your system administrator if you’re in a corporate environment. The minimum requirements are more than sufficient for most modern computers.
Windows 7
Preceded by Windows Vista and succeeded by Windows 10, it offers improved start-up times, support for multi-touch on touch screen displays, and better performance. Windows 7 also features Aero, an interface that makes it easier to interact with the desktop, and provides a preview of open windows in the task bar.
While it’s a good idea to upgrade to a more modern operating system, Windows 7 will continue to work as long as you have the original license and continue to get updates from Microsoft. However, without security patches (which ended in January 2020), a computer running Windows 7 will be vulnerable to hacking and viruses.
Windows 8
Windows 8 has a tiled interface that works well on touchscreens. It has a new taskbar that spans multiple displays and allows each display to show its own dedicated task bar. It also has an improved multi-monitor configuration tool, and it supports different wallpapers per display.
The operating system is available in four editions, including the standard Windows 8, Windows 8 Pro, and Windows RT, which runs on tablet computers with ARM architecture. This version uses fewer resources and can run on devices with limited memory. It also has a wide range of security features, such as UEFI Secure Boot and SmartScreen phishing filtering.
Windows 10
Released in 2015, Windows 10 is regarded as Microsoft’s most adaptable and user-friendly operating system yet. It also features built-in security tools designed to complement antivirus software.
There’s also a full version of the OS, called Windows 10 S, that’s intended for low-cost laptops and education-oriented computers. It runs apps from the Microsoft Store and ensures that your data is protected with Windows Defender.
Windows 10 operates as a service, with updates released twice per year. This means your device will receive new features and capabilities without requiring you to install a major update. You can manage your updates and security settings through the Windows Settings.
