The x86 protection model is notoriously complex, with four privilege rings, segmentation, paging, call gates, task switches, and virtual 8086 mode. What's interesting from a hardware perspective is how the 386 manages this complexity on a 275,000-transistor budget. The 386 employs a variety of techniques to implement protection: a dedicated PLA for protection checking, a hardware state machine for page table walks, segment and paging caches, and microcode for everything else.

If you’re a casual college basketball fan, an option like Sling may be a good fit for you. It's a comprehensive sporting service with a wide range of benefits, but you will need to be careful when selecting your plan. The Orange and Blue packages give you access to FOX, NBC, ABC, ESPN, and more in local markets — for $45.99 per month (with an introductory deal of 50% off for the first month) — but for access to ACC Network, SEC Network, Big Ten Network, and more, you'll need the Sports Extra package. We recommend checking your local market to ensure you get access to the channels you actually want.
