Home Sharing in Catalina does not require you to have an app open for it to work. The Music app uses the former iTunes logo, with a music note on a field of white. It looks similar to the Music function housed in iTunes in Mojave, offering up access to music you've purchased, imported, or acquired through Apple Music.

Sidecar is designed to let you use an iPad as a secondary display with your Mac. You can hold your mouse over the green button on any Mac app window to get into Sidecar mode with an available iPad, you can access it from the System Preferences app, or you can access it from the AirPlay interface on the Mac.
Sidecar lets you either mirror your display or extend it to the iPad, and because the Apple Pencil works in Sidecar mode, you can use the Apple Pencil as a mouse or as a drawing implement in apps like Photoshop.

The Find My app is designed to make it easy to locate your devices and your friends who are sharing their location in a single app. Find My works like the previous Find My iPhone and Find My Friends apps, displaying device and friend locations, but there's a new feature that lets you find a missing Mac even when it doesn't have a WiFi or cellular connection. The Find My feature works by utilizing crowd-sourced location information delivered through Bluetooth signals.
Basically, your devices give off a Bluetooth signal that can be picked up by other nearby iPhones, iPads, and Macs, relaying that signal back to you so you can find your missing device. Find My uses end-to-end encryption to keep your location safe, so it requires at least two Apple devices to work, aka your Mac and an iPhone or other device.
The signal that your Mac gives off is broadcast as a public key, which, when picked up by other people's devices, is encrypted and sent back to you with the location of your device. Only another one of your devices can decrypt that encrypted signal with info from the lost device, keeping your device location secure at all times.

These viewing modes filter out clutter like screenshots, duplicate images, and photos of receipts so you can see your most significant moments without the cruft. In the new Photos tab, muted Live Photos and videos play as you scroll, which has the effect of bringing your photo library to life.
The best of your photos are also shown larger, accompanied by smaller shots, making your photo library more dynamic. The Days view shows the photos you've taken that day, while the Months view presents your photos categorized into events so you can see the best of the month at a glance.

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.
Some operating systems are designed by groups of people around the world, like the open source, freely available operating system Linux, while others are commercial products made by one company, such as Microsoft's Windows and Apple's macOS. Different operating systems run on different types of hardware and are designed for different types of applications. Your computer or smartphone comes equipped with an OS, but you can install another one in some cases.
