Processor Lenovo Z50-70 (59-436412)
Processor: A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.
Intel Core i5-4210U
Processor Speed: The clock rate typically refers to the frequency at which a chip like a central processing unit (CPU), one core of a multi-core processor, is running and is used as an indicator of the processors speed. It is measured in clock cycles per second or its equivalent, the SI unit hertz (Hz). The clock rate of the first generation of computers was measured in hertz or kilohertz (kHz), but in the 21st century the speed of modern CPUs is commonly advertised in gigahertz (GHz). This metric is most useful when comparing processors within the same family, holding constant other features that may impact performance.
Cache: A CPU cache is a cache used by the central processing unit (CPU) of a computer to reduce the average time to access data from the main memory. The cache is a smaller, faster memory which stores copies of the data from frequently used main memory locations. Most CPUs have different independent caches, including instruction and data caches, where the data cache is usually organized as a hierarchy of more cache levels (L1, L2, etc.).
Memory Lenovo Z50-70 (59-436412)
RAM: People in the computer industry commonly use the term "memory" to refer to RAM (Random Access Memory). As your processor cranks on your game, it uses RAM to store some of the data needed to make your game work. While all forms of memory work together, RAM is considered the main memory since most data, regardless of its source, is stored in RAM before it is registered in any other storage device. Consequently, RAM is used millions of times every second. A computer uses Ram to hold temporary instructions and data needed to complete tasks. This enables the computers CPU (Central Processing Unit), to access instructions and data stored in memory very quickly.
Memory Type: Random access memory (RAM) is the best known form of computer memory. RAM is considered "random access" because you can access any memory cell directly if you know the row and column that intersect at that cell. A computers system RAM alone is not fast enough to match the speed of the CPU. That is why you need a cache (discussed later). However, the faster RAM is, the better. Most chips today operate with a cycle rate of 50 to 70 nanoseconds. The read/write speed is typically a function of the type of RAM used, such as DRAM, SDRAM, RAMBUS.
Hard Drive Lenovo Z50-70 (59-436412)
Hard Drive Size: The amount of storage on a hard disk, measured in gigabytes and terabytes. Hard drive capacity is generally measured by the amount of data users need to store, which is usually much greater than the space applications take up.
Hard Drive RPM: Short for Revolutions Per Minute, RPM is used to help determine the access time on computer hard drives. RPM is a measurement of how many revolutions a computers hard drive makes in a single minute. The higher the RPM, the faster the data will be accessed; for example, if you were comparing two hard drives, one with 5400 RPM and another with 7200 RPM, the hard drive with a 7200 RPM will be capable of accessing data much faster than the other.
Display Lenovo Z50-70 (59-436412)
Screen Size: Display size (or viewable image size or VIS) is the physical size of the area where pictures and videos are displayed. The size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners, usually in inches.
Screen Resolution The number of horizontal and vertical pixels on a display screen. The more pixels, the more information is visible without scrolling. Screen resolutions have a pixel count such as 1600x1200, which means 1,600 horizontal pixels and 1,200 vertical pixels.

GPU Model: Notebooks with switchable graphics have been shipping for years, but they havent lived up to user expectations. Nvidia hopes to change that with their new Optimus technology.The first notebooks with switchable graphics had a physical switch to toggle between the integrated and discrete GPU, and required you to reboot the system to switch from one to the other. More recently, you could change between the integrated and discrete GPU with software - using a small tool-tray icon or changing the power profile in Windows.
GPU Memory (shared): Graphics memory is often used by card vendors as a marketing tool. Because gamers have been conditioned to believe that more is better, it is common to see entry-level boards with far more RAM than they need. But enthusiasts know that, as with every subsystem in their PCs, balance is most important. In computer architecture, shared graphics memory refers to a design where the graphics chip does not have its own dedicated memory, and instead shares the main system RAM with the CPU and other components.
HDMI Port: HDMI (High-Definition Multimedia Interface) is a proprietary audio/video interface for transferring uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device.
Network Lenovo Z50-70 (59-436412)
Ethernet Port: An Ethernet port is an opening on computer network equipment that Ethernet cables plug into. Ethernet ports accept cables with RJ-45 connectors.
Ethernet Type: Ethernet is the collective name for a variety of closely related network standards. As a network standard, each version of Ethernet includes specifications for the physical network layer: how the signals will be sent and received. Protocols like IP or NetWare, in contrast, define communications without reference to the physical transport medium. OmniPeek is only interested in that aspect of each version of Ethernet that is reflected in the construction of Ethernet packets or network frames. It treats the various Ethernet standards as if they were protocols, discriminating among them based on the unique form each one gives to packet headers and trailers.
WiFi Type: Wi-Fi (or WiFi) is a local area wireless computer networking technology that allows electronic devices to connect to the network, mainly using the 2.4 gigahertz (12 cm) UHF and 5 gigahertz (6 cm) SHF ISM radio bands.

Bluetooth: Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices, and building personal area networks (PANs). Invented by telecom vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.
Digital Media Reader: This driver enables the PC to read and write to supported removable storage cards and is required to connect the reader the PC. - Read more at http://www.shouldiremoveit.com/Digital-Media-Reader-21019-program.aspx
Battery Lenovo Z50-70 (59-436412)
Battery Chemistry: An electric battery is a device consisting of two or more electrochemical cells that convert stored chemical energy into electrical energy. Each cell has a positive terminal, or cathode, and a negative terminal, or anode. The terminal marked positive is at a higher electrical potential energy than is the terminal marked negative. The terminal marked positive is the source of electrons that when connected to an external circuit will flow and deliver energy to an external device. When a battery is connected to an external circuit, electrolytes are able to move as ions within, allowing the chemical reactions to be completed at the separate terminals and so deliver energy to the external circuit. It is the movement of those ions within the battery which allows current to flow out of the battery to perform work.
Software Lenovo Z50-70 (59-436412)
Operating System: An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. The operating system is a component of the system software in a computer system. Application programs usually require an operating system to function.
