Suitable for gaming
Suitable for gamingAll systems can play casual games such as solitaire and Angry Birds. Systems designated as suitable for gaming are more powerful and can play modern mainstream and intensive 3D video games with a frame rate and visual effects that does not make the game stop or stutter.
Blu-ray or DVD
Blu-ray or DVDHas either a Blu-Ray drive (B), which lets you watch Blu-Ray movies and read/write to CDs and DVDs, or a DVD drive (D), which lets you read/write to CDs and DVDs. Some computers have no optical drive installed (—).
Memory-card readerAt least one flash memory-card slot (CF, SD, XD, MS, etc.)
Facial recognitionWebcam can be set to scan your face for secure log-in.
Fingerprint readerA biometric fingerprint reader for logging into your PC.
Hand gesture control
Hand gesture controlHand gesture control allows you to use specific hand motions to control your computer. Depending on the software you can do things like raise and lower volume, scroll up and down, zoom in and out and open and close applications.
Display sizeThe diagonal measure of the LCD (Liquid Crystal Display) screen.
Operating system (as tested)
Operating system (as tested)The operating system that was installed on the computer at the time it was tested. The operating system is the software that controls the basic operation of the computer. Common examples are Windows and Mac OS. The operating system determines the "look and feel" of the PC.
Windows 10 Home
ProcessorAlso known as the CPU (Central Processing Unit), the processor is responsible for running commands and handling data. Processors come in different speeds and may have two or more cores (ex. dual-core), which let you more quickly process multiple complex tasks.

Processor brandAlso known as the CPU (Central Processing Unit), the processor is responsible for running commands and handling data. Processors come in different speeds and may have two or more cores (ex. dual-core), which let you more quickly process multiple complex tasks. This is the brand, or manufacturer, of the processor.

MemoryAlso known as RAM, memory is a temporary storage area for data. Its size is an important factor for performance. We recommend at least 4GB of memory, or 8GB if you plan to run several large applications at the same time.
StorageThe amount of storage, a permanent area for the operating system, programs and data such as documents, music, and media files. Storage can be a hard drive, an SSD (solid state drive), or hybrid drive.
Video memoryThe amount of dedicated memory built into a graphics adapter. Most models have integrated graphics, which have no dedicated memory but are still suitable for most applications, including photo editing and watching movies. Others have discrete graphic adapters, which typically have 1 GB or more of dedicated video memory, to deliver smoother and more realistic graphics for 3D games.
Native resolutionThe number of picture elements ("pixels") across the horizontal and vertical dimension of the screen. The higher the resolution within a given size screen, the finer the detail that can be displayed. No scaling is needed to view a picture or movie of this size, or to match the display resolution with the native resolution, sometimes called Default or Recommended.

Video adapterAlso known as the video card, the video adapter processes all the data that you see on your screen. They come in different speeds and may be integrated (most common, but is slower and uses up memory) or discrete (which is faster and has its own dedicated memory). If you will not be playing complex 3D games, any integrated graphics adapter will do. Otherwise, buy a discrete graphics adapter with a graphics processor from ATI or Nvidia with at least 256 MB of memory.
Optical driveThe optical drive reads and/or writes to CDs and DVDs. Most PCs come equipped with a DVD-RW, also known as a DVD burner, which lets you read and write to DVDs. Some models come with Blu-Ray drives, which let you play high-definition movies.
HeightThe height from the table, or thickness, of the computer while closed. This includes the keyboard dock on detachable laptops.
DepthThe depth, from the front edge to the back hinge, of the computer while closed. This includes the keyboard dock for detachable laptops.
WidthThe width of the computer while closed. This includes the keyboard dock of detachable laptops.
Thin and light
Thin and lightBased on weight and thickness. This includes laptops that may be labeled "Ultrabook," "Sleekbook," "Thin and light," and "Ultrathin," among other terms.
Warranty lengthThe length in months of the manufacturer's standard warranty.
Tech support length
Tech support lengthThe length in months of the manufacturer's free technical support by telephone.
Battery capacityThe total energy contained in the battery, expressed in Watt-hours. A larger capacity battery will deliver longer battery life, but will add weight and sometimes will extend beyond the edge of the laptop.
Comes in S Mode
Comes in S ModeWindows computers that come in S Mode can only run apps from the Microsoft Store. This is one way to ensure system security and stability. They can be switched out of S Mode for free, allowing them to run third-party applications. We test computers switched out of S Mode.
LCD resolutionThe number of picture elements ("pixels") across the horizontal and vertical dimension of the screen. The higher the resolution within a given size screen, the finer the detail that can be displayed.

EPEAT levelEPEAT (Electronic Product Environment Assessment Tool) certification, based on environmental attributes such as the types of materials used and power consumption. There are three levels (in increasing order of environmental performance): bronze, silver, and gold. Products without an EPEAT level either do not meet EPEAT's minimum requirements or have not yet been tested by EPEAT.
