New "preview" videos allow developers to visually show an app's function. HealthKit is a service that allows developers to make apps that integrate with the new Health app. The Health app primarily aggregates data from fitness apps installed on the user's device, except for steps and flights climbed, which are tracked through the motion processor on the user's iPhone. Users can enter their medical history in Medical ID, which is accessible on the lock screen, in case of an emergency. HomeKit serves as a software framework that lets users set up their iPhone to configure, communicate with, and control smart-home appliances. By designing rooms, items and actions in the HomeKit service, users can enable automatic actions in the house through a simple voice dictation to Siri or through apps. HomeKit products are required to have an encryption co-processor. Equipment manufactured without HomeKit-support can be enabled for use through a "gateway" product, such as a hub that connects between those devices and the HomeKit service. A new music streaming service, Apple Music, was introduced in the iOS 8.4 update. It allows subscribers to listen to an unlimited number of songs on-demand through subscriptions.
In contrast, software emulated sprites found on systems without support for hardware sprites such as the Apple II and ZX Spectrum required a bitmapped screen. Sprite-sprite and sprite-background collisions are detected in hardware and the VIC-II can be programmed to trigger an interrupt accordingly. The SID chip has three channels, each with its own ADSR envelope generator and filter capabilities. Ring modulation makes use of channel no. 3, to work with the other two channels. Bob Yannes developed the SID chip and later co-founded synthesizer company Ensoniq. Often the game music has become a hit of its own among C64 users. Well-known composers and programmers of game music on the C64 are Rob Hubbard, Jeroen Tel, Tim Follin, David Whittaker, Chris Hülsbeck, Ben Daglish, Martin Galway, Kjell Nordbø and David Dunn among many others. Due to the chip's three channels, chords are often played as arpeggios, coining the C64's characteristic lively sound. It was also possible to continuously update the master volume with sampled data to enable the playback of 4-bit digitized audio.

Before Thunderbolt 3, which started appearing in laptops at the end of 2015, there was a Thunderbolt 2 and original Thunderbolt standard, but very few systems used them. With an adapter cable, you can connect your Thunderbolt 3 computer to older Thunderbolt devices. Adapters Needed: You can get a Thunderbolt 3 cable (opens in new tab) for under $25, but be sure to read the specs before you buy; not all Thunderbolt cables can handle the full 40 Gbps, with some topping out at 20 Gbps. Thunderbolt 3 docking stations, which let you plug into a variety of monitors and peripherals, go for around $200. You can also use any USB Type-C cable, dock or device with a Thunderbolt 3 port. A Thunderbolt 3-to-Thunderbolt adapter for attaching to legacy Thunderbolt devices is pricey, going for over $100. Description: The great granddad of video outputs, VGA (video graphics array) dates all the way back to 1987 but is still commonplace on many monitors and projectors today. However, because the 15-pin connector is rather chunky, you won't find too many current-gen laptops or desktops that have VGA-out. It is an analog connection, which could lead to signal degradation over longer cables, and it outputs at only up to 1920 x 1200, so it's the least desirable port. Adapters Needed: You can't convert VGA to any other display standard (DVI, DisplayPort, HDMI), but you can plug any other connector into a VGA monitor with an inexpensive wire or adapter. You can get DVI-to-VGA (opens in new tab), HDMI-to-VGA (opens in new tab) or DisplayPort-to-VGA (opens in new tab) converters for under $10. Should I Buy a Chromebook?
