MacBook Air
The MacBook Air is a line of ultrabook computers developed and manufactured by Apple Inc. It consists of a full-size keyboard, a machined aluminum case, and, in the more modern versions, a thin light structure. The Air was originally positioned above the previous MacBook line as a premium ultraportable. Since then, the original MacBook's discontinuation in 2011, and lowered prices on subsequent iterations, have made the Air Apple's entry-level notebook. In the current product line, the MacBook Air is situated below the performance range MacBook Pro. The Intel-based MacBook Air was introduced in January 2008 with a 13.3-inch screen, and was promoted as the world's thinnest notebook, opening a laptop category known as the ultrabook family. Apple released a second-generation MacBook Air in October 2010, with a redesigned tapered chassis, standard solid-state storage, and added a smaller 11.6-inch version. Later revisions added Intel Core i5 or i7 processors and Thunderbol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aluminum
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity towa ...

MacBook (2006–2012)
The MacBook is a line of Macintosh notebook computers designed, manufactured and sold by Apple Inc. from May 2006 to February 2012. A new line of computers by the same name was released in 2015, serving the same purpose as an entry-level laptop. It replaced the iBook series of notebooks as a part of Apple's transition from PowerPC to Intel processors. Positioned as the low end of the MacBook family, below the premium ultra-portable MacBook Air and the powerful MacBook Pro, the MacBook was aimed at the consumer and education markets. It was the best-selling Macintosh ever. For five months in 2008, it was the best-selling laptop of any brand in US retail stores. Collectively, the MacBook brand is the "world's top-selling line of premium laptops." There have been three separate designs of the MacBook. The original model used a combination of polycarbonate and fiberglass casing which was modeled after the iBook G4. The second type was introduced in October 2008 alongside t ...

Solid-state Drive
A solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies to store data persistently, typically using flash memory, and functioning as secondary storage in the hierarchy of computer storage. It is also sometimes called a semiconductor storage device, a solid-state device or a solid-state disk, even though SSDs lack the physical spinning disks and movable read–write heads used in hard disk drives (HDDs) and floppy disks. SSD also has rich internal parallelism for data processing. In comparison to hard disk drives and similar electromechanical media which use moving parts, SSDs are typically more resistant to physical shock, run silently, and have higher input/output rates and lower latency. SSDs store data in semiconductor cells. cells can contain between 1 and 4 bits of data. SSD storage devices vary in their properties according to the number of bits stored in each cell, with single-bit cells ("Single Level Cells" or "SLC") ...

Central Processing Unit
A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program. This contrasts with external components such as main memory and I/O circuitry, and specialized processors such as graphics processing units (GPUs). The form, design, and implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic–logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that orchestrates the fetching (from memory), decoding and execution (of instructions) by directing the coordinated operations of the ALU, registers and o ...

Thunderbolt (interface)
Thunderbolt is the brand name of a hardware interface for the connection of external peripherals to a computer. It has been developed by Intel, in collaboration with Apple. It was initially marketed under the name Light Peak, and first sold as part of an end-user product on 24 February 2011. Thunderbolt combines PCI Express (PCIe) and DisplayPort (DP) into two serial signals, and additionally provides DC power, all in one cable. Up to six peripherals may be supported by one connector through various topologies. Thunderbolt 1 and 2 use the same connector as Mini DisplayPort (MDP), whereas Thunderbolt 3 and 4 reuse the USB-C connector from USB. Description Thunderbolt controllers multiplex one or more individual data lanes from connected PCIe and DisplayPort devices for transmission via two duplex Thunderbolt lanes, then de-multiplex them for use by PCIe and DisplayPort devices on the other end. A single Thunderbolt port supports up to six Thunderbolt devices via hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subnotebook
Subnotebook, also called ultraportable, superportable, or mini notebook, was a marketing term for laptop computers that are smaller and lighter than a typical notebook-sized laptop. Types and sizes As typical laptop sizes have decreased over the course of the 2010s, and other distinguishing features have become mainstream, the distinction between regular-size and 'subnotebook' laptops has largely disappeared. To the extent that it still exists, 'subnotebook' could be defined as machines with screen smaller than 13" but with a permanently-attached keyboard intended for two-handed typing. Prior to this convergence, subnotebooks were also distinguished from netbooks and ultra-mobile PCs, based on both size and market position. Classic subnotebooks were smaller than full sized laptops but larger than handheld computers. They were distinguished by smaller screens and bodies and lighter weights relative to contemporaneous laptops. The savings in size and weight were often achieved ...

USB-C
USB-C (properly known as USB Type-C) is a 24-pin USB connector system with a rotationally symmetrical Electrical connector, connector. The designation C refers only to the connector's physical configuration or form factor and should not be confused with the connector's specific capabilities, which are designated by its transfer specifications (such as USB 3.2). A notable feature of the USB-C connector is its ''reversibility''; a plug may be inserted into a receptacle in either orientation. The ''USB Type-C Specification 1.0'' was published by the USB Implementers Forum (USB-IF) and was finalized in August 2014. It was developed at roughly the same time as the USB 3.1 specification. In July 2016, it was adopted by the International Electrotechnical Commission, IEC as "IEC 62680-1-3". A device with a Type-C connector does not necessarily implement USB, USB Power Delivery, or any USB-C#Alternate Mode, Alternate Mode: the Type-C connector is common to several technolog ...

Machining
Machining is a process in which a material (often metal) is cut to a desired final shape and size by a controlled material-removal process. The processes that have this common theme are collectively called subtractive manufacturing, which utilizes machine tools, in contrast to '' additive manufacturing'' (3D printing), which uses controlled addition of material. Machining is a part of the manufacture of many metal products, but it can also be used on other materials such as wood, plastic, ceramic, and composite material. A person who specializes in machining is called a machinist. A room, building, or company where machining is done is called a machine shop. Much of modern-day machining is carried out by computer numerical control (CNC), in which computers are used to control the movement and operation of the mills, lathes, and other cutting machines. This increases efficiency, as the CNC machine runs unmanned therefore reducing labour costs for machine shops. History and ter ...
