OS Origins - IBM to iOS

Let's take a break from coding and look at the history of Operating Systems

## Humble Beginnings

The first computers were clunky, worthless (by today's standards), and took up an entire room or two. They ran off of programs that were hand-encoded and fed into the machine. Runtime-Libraries weren't introduced until the early 1950's and the "kernel" was introduced around that time.
One of the more popular OSes around the time was MUNIX, which was specifically designed for terminals, and had time sharing and user accounts. It also had a lot of error handling code, which made it bulky and also computationally intensive, sometimes taking nearly half of the available memory on the main computer. After that, a more popular os, UNIX was developed. It was much simpler, and would go into kernel panic whenever an error occured and the system would have to be rebooted. This disadvantage also is its advantage, as it can run on less memory.

GNU was a open source port of UNIX(Which was IBM's property), and later became GNU/Linux.

The first operating system was GM-NAA I/O, created in 1956 created by General Motors for it's IBM 704. Then, in the 60's, IBM released OS/360, and later in the 1980's MS-DOS.

## Rise of Home Computing

Bob Dylan famously said "The times, they are a-changin'". That's true with the 1990's. IF you've seen A E S T H E T I C art on the internet, you know that Windows was the dominant operating system back in the day. Windows 95, to be exact. Windows 98 followed soon after, then 2000, ME (Millennium Edition), and XP. In the 1980's, Apple released Mac OS, later named OS X. In 1991, Linus Torvalds (I believe that's how you say his last name) created Linux, another Unix-based operating system.

## Mobile Computing

On June 29, 2007, Apple released the iPhone, and with it came iOS (iPhone Operating System). The first-generation iPhone was announced by then-Apple CEO Steve Jobs on January 9, 2007. Since then, Apple has annually released new iPhone models and iOS updates. As of November 1, 2018, more than 2.2 billion iPhones had been sold. As of 2022, the iPhone accounts for 15.6% of global smartphone market share.

The iPhone was the first mobile phone to use multi-touch technology. Since the iPhone's launch, it has gained larger screen sizes, video-recording, waterproofing, and many accessibility features. Up to the iPhone 8 and 8 Plus, iPhones had a single button on the front panel with the Touch ID fingerprint sensor. Since the iPhone X, iPhone models have switched to a nearly bezel-less front screen design with Face ID facial recognition, and app switching activated by gestures. Touch ID is still used for the budget iPhone SE series.

On October 21, 2010, Microsoft released the Windows Phone. Windows Phone 8 succeeded it in 2012, replacing the Windows CE-based kernel of Windows Phone 7 with the Windows NT kernel used by the PC versions of Windows (and, in particular, a large amount of internal components from Windows 8.) Due to these changes, the OS was incompatible with all existing Windows Phone 7 devices, although it still supported apps originally developed for Windows Phone 7. In 2014, Microsoft released the Windows Phone 8.1 update, which introduced the Cortana virtual assistant, and Windows Runtime platform support to create cross-platform apps between Windows PCs and Windows Phone.

So now you know the history of the Operating System. Let's continue
