iCloud, Siri & more

What is iCloud?  
Cloud connects you and your Apple devices in amazing ways. It makes sure you always have the latest versions of your important information—like documents, photos, notes, and contacts—on whatever device you’re using. It lets you easily share photos, calendars, locations, and more with friends and family. It even helps you find your device if you lose it.
iCloud photo stream vs. iCloud photo library 

There are a few key differences between iCloud Photo Library and Photo Stream that you need to remember. Here's a brief overview:
Regular Photo Stream: Only stores your most recent 1000 photos or the last 30 days of images, whichever is greater

  • Does not use your iCloud storage allotment\
  • Compatible across all devices including iPhone, iPad, Mac, and PC
  • Stores web-optimized versions of your photos, which may degrade quality
  • You can still sync photos and albums from your Mac or PC via iTunes when Photo Stream is enabled

Cloud Photo Library:

  • Stores all your photos and personal video and has no limits as long as you have the iCloud storage space to support it
  • Uses your iCloud storage allotment
  • Accessible on iPhone, iPad, Mac, and online via iCloud.com
  • Stores full-resolution photos on the server and on your devices and supports many file formats including JPG, RAW, PNG, GIF, TIFF, and others
  • Uploads and syncs videos as well as photos
  • You can not sync albums and photos from your Mac or PC via iTunes when using iCloud Photo Library, and any existing albums will be removed when you enable the service
  • Does not upload and sync videos
iCloud Backup
    • iCloud automatically backs up the information on your devices—iPhone, iPad, and iPod touch—over Wi-Fi every day when they are turned on, locked, and connected to a power source. When your iOS device information is backed up in iCloud, you can easily set up a new device or restore information on one you already have. Here’s what iCloud backs up:

      • Purchase history for music, movies, TV shows, apps, and books .Your iCloud backup includes information about the content you purchased, but not the purchased content itself. When you restore from an iCloud backup, your purchased content is automatically downloaded from the iTunes Store, App Store, or iBooks Store.

      • Photos and videos on your iOS devices

        However, if you turn on iCloud Photo Library on your iOS device (iOS 8.1 or later) or Mac (OS X v10.10.3 or later), your photos and videos are already stored in iCloud, so they aren’t included in your iCloud backup.

      • Device settings

      • App data

      • Home screen and app organization

      • iMessage, text (SMS), and MMS messages (requires the SIM card that was in use during backup)

      • Ringtones

      • Visual Voicemail password (requires the SIM card that was in use during backup)

      • Health data

      • HomeKit configuration

      Apple Watch content is backed up automatically to your paired iPhone.

      Your iOS device backup only includes data and settings stored on your device. It doesn’t include data already stored in iCloud. That includes contacts, calendars, bookmarks, mail messages, notes, shared photo albums, iCloud Photo Library, My Photo Stream, and documents you store in iCloud Drive. If your iOS device isn’t set up for iCloud Drive, but is set up for iCloud Documents & Data, your documents stored in iCloud are backed up.

Siri Siri is a built-in, voice-controlled personal assistant available for Apple users. The idea is that you talk to her as you would a friend and she aims to help you get things done, whether that be making a dinner reservation or sending a message.
Siri is designed to offer you a seamless way of interacting with your iPhone/iPad iPod Touch or Apple Watch by you speaking to her and her speaking back to you to find or do what you need. You can ask her questions, tell her to show you something or issue her with commands for her to execute on your behalf, hands-free.
Siri has access to every other built-in application on your Apple  device - Mail, Contacts, Messages, Maps, Safari, etc - and will call upon those apps to present data or search through their databases whenever she needs to. Ultimately, Siri does all the legwork for you. It means you can carry out a single task by just saying "Hey Siri" or double tapping the Home button, rather than open multiple apps or spend time writing messages or finding contacts.
