Basic characteristics Spec Apple MacBook Air MQD42PP/A (Mid 2017)
CPU: CPU (pronounced as separate letters) is the abbreviation for central processing unit. Sometimes referred to simply as the central processor, but more commonly called processor, the CPU is the brains of the computer where most calculations take place. In terms of computing power, the CPU is the most important element of a computer system.

Processor Speed: The speed at which your computer runs programs or completes tasks is determined in great measure by your computer's processor speed. Processor speed is measured in gigahertz (GHz). The higher this measurement, the faster the processor. It's hard to say the speed you should look for because these chips are constantly getting smaller and contain more and more power. However, when you shop, know that the higher numbers give the best performance and factor that into your decision depending on your needs.

Memory & Storage Apple MacBook Air MQD42PP/A (Mid 2017)
RAM: RAM (pronounced ramm) is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers.
Memory Type: In computing, DDR3 SDRAM, an abbreviation for double data rate type three synchronous dynamic random-access memory, is a modern type of dynamic random-access memory (DRAM) with a high bandwidth ("double data rate") interface, and has been in use since 2007. It is the higher-speed successor to DDR and DDR2 and predecessor to DDR4 synchronous dynamic random-access memory (SDRAM) chips. DDR3 SDRAM is neither forward nor backward compatible with any earlier type of random-access memory (RAM) because of different signaling voltages, timings, and other factors.
Memory Speed: RAM is normally rated at its highest tested stable speed, first by the chip manufacturer in cycle time (measured in nanoseconds, abbreviated ns), then by the module producer in frequency (megahertz, or MHz). Because of the inverse relationship between cycle time and frequency, knowing the rated frequency for a single chip is as easy as inverting cycle time and moving the decimal place. For example, 200 MHz SDRAM would be equivalent to 5 ns, because 5 ns equals 0.005 microseconds, and 1 divided by 0.005 equals 200.

Display Size: The size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners. It is also sometimes called the physical image size to distinguish it from the logical image size,which describes a screens display resolution and is measured in pixels.
Resolution: Image resolution can be measured in various ways. Basically, resolution quantifies how close lines can be to each other and still be visibly resolved. Resolution units can be tied to physical sizes (e.g. lines per mm, lines per inch), to the overall size of a picture (lines per picture height, also known simply as lines, TV lines, or TVL), or to angular subtenant. Line pairs are often used instead of lines; a line pair comprises a dark line and an adjacent light line.

Network Apple MacBook Air MQD42PP/A (Mid 2017)
WiFi: WiFi is a technology that uses radio waves to provide network connectivity. A WiFi connection is established using a wireless adapter to create hotspots - areas in the vicinity of a wireless router that are connected to the network and allow users to access internet services. Once configured, WiFi provides wireless connectivity to your devices by emitting frequencies between 2.4GHz - 5GHz, based on the amount of data on the network.

Software Apple MacBook Air MQD42PP/A (Mid 2017)
OS: An operating system (OS) is the program that, after being initially loaded into the computer by a boot program, manages all the other programs in a computer. The other programs are called applications or application programs. The application programs make use of the operating system by making requests for services through a defined application program interface (API). In addition, users can interact directly with the operating system through a user interface such as a command line or a graphical user interface (GUI).
