Processor Speed The clock speed of the processor, measured in hertz (Hz), is defined as the number of operations the central processing unit (CPU) can carry out in a single second. Working in combination with system memory, the power of the processor determines the complexity of software you can run, how many programs you can have open at the same time, and how fast those programs will run.
Processor Model Your computer's processor is like its brain. Working in combination with system memory, the power of the processor determines the complexity of software you can run, how many programs you can have open at the same time, and how fast those programs will run. Most computers feature an Intel or AMD processor.

System Memory (RAM) Random-access memory, or RAM, is important because it helps your processor tackle multiple tasks at once. A minimum of 2GB is required for basic computing, but 6GB or more is recommended if you're into graphics and advanced photo or video editing.

Certifications & Listings
ENERGY STAR Certified Devices carrying the Energy Star service mark, such as computer products and peripherals, kitchen appliances, buildings and other products, generally use 20% to 30% less energy than required by federal standards.
EPEAT Qualified The Electronic Product Environmental Assessment Tool (EPEAT) was designed to provide an environmental assessment tool for purchasers. In order to qualify for EPEAT, a product must meet all 23 required criteria.
Graphics Type There are two types of graphics: dedicated/discrete graphics card and integrated graphics. A dedicated graphics card has its own random-access memory (RAM), its own cooling system, and dedicated power regulators, with all components designed specifically for processing video images. Integrated graphics is the video hardware that is integrated into the motherboard or the CPU. In a PC with integrated graphics, the graphics processor shares system resources (like memory) with the CPU.
Graphics Processing Unit/GPU
Video Memory Type
Video Memory The workspace of the graphics card, the video memory temporarily stores data the graphics card is handling. This allows faster access to data and improves graphics performance. If a computer uses integrated graphics, the GPU will share the computer's memory (RAM).
Photos, iMovie, GarageBand
Additional Accessories Included
Magic Keyboard, Magic Mouse 2
Media Card Reader Media card reader is a hardware device that lets you read and write data on a memory card such as a multimedia card.
Type of Memory (RAM) Different types of RAM are available; some of the most common are DDR4, DDR3 and DDR2. Each type of RAM delivers a different level of speed, bandwidth, energy efficiency and performance.

Number Of USB Port(s)
Port Type(s) USB 2.0 connects external drives, gaming controllers, smartphones, MP3 players and other accessories. USB 3.0 transfers data faster than USB 2.0, but only when used with USB 3.0 devices. USB Type-C provides fast speeds and versatile power, featuring connectors with identical ends that plug in upside down or right side up. Adapters allow for video as well as backward compatibility. Thunderbolt provides ultra-high bandwidth for fast data transfer between devices featuring a Thunderbolt or MiniDisplayPort connection. HDMI allows you to connect a projector or display HD media on your HDTV or monitor. Media card slots allow you to transfer photos from your digital camera or camcorder.
Wireless Networking This device can connect via Wi-Fi to other devices without using cables or cords.
