Types of Operating Systems
The operating system is the heart of your laptop. It manages all software and hardware, including files, memory and connected devices. Most importantly, it lets you interact with your laptop and your programs in a visual way (otherwise, you'd be typing a bunch of computer code to get anything done).

Installed exclusively on Mac computers, OS X boasts an elegant and easy-to-use interface to complement Macs' sleek aesthetics and impressive battery life. Macs have historically had fewer issues with viruses and malware. However, MacBooks start at a higher price point than other laptops, and no Mac model to date includes touch-screen functionality.

Windows is designed specifically around an intuitive touch-screen interface (though it can be used with a traditional mouse and keyboard), expanding your navigation options. The integrated Windows Hello feature lets you log in quickly using a look or a touch instead of a password, while remaining enterprise-grade secure. It also offers an updated task manager, streamlined file management and a suite of built-in apps.
Select touch-screen laptops are also equipped for Windows Ink, which lets you write or draw on the display and interact with a wide range of Windows Ink-enabled apps, using a compatible pen accessory (may be sold separately).

Featured exclusively in the Chromebook line of mobile computers, this OS runs custom apps and cloud-based programs rather than traditional software. It's great for surfing the Web, keeping up with your email and social networks, and sharing your photos with friends and family, rather than more data-intensive tasks like video editing and hardcore gaming.

Intel's processors are at the heart of every modern MacBook and the majority of Windows laptops. Most prevalent are Intel's Core™ series of multicore processors:
- Core X-Series:Intel's ultimate processor for gaming and virtual reality experiences. The Core X-series family offers up to 18 cores and 36 threads to power through the creation, editing and production of 4K or 360° videos, high-resolution photos and high-quality audio.
- Core i7:A popular choice for "power users" like hardcore gamers, graphic designers, photographers and videographers. It excels at serious multitasking and high-demand multimedia creation for projects in 3D or high definition.
- Core i5:Mid-grade Core processor is powerful enough for most computing tasks, and multitasks well so you can stream the big football game while looking up stats and sending emails.
- Core i3:The entry-level Core processor, more than adequate for everyday email, internet and productivity tasks. It's also fine for common activities like listening to music.

In value-priced laptops, you'll also see Intel's Pentium® and Celeron® processors. These are adequate for basic email, internet and productivity tasks, but their speed and multitasking capabilities are limited relative to those of the Core family.
