Processor Toshiba Tecra R850-14C (PT525E-00H00KGR)
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.
Intel Core i5-2xxx
Processor: A processor is the logic circuitry that responds to and processes the basic instructions that drive a computer. The four primary functions of a processor are fetch, decode, execute and writeback.
Processor boost frequency: Turbo Boost is automatic. It will scale up the frequency by itself as and when required while keeping it from overheating. You can not control it yourself, but you do not need to, it works very reliably by reducing the frequency when you do not need it to save power and increasing it when you need it to give you more performance.
Processor core: A multi-core processor is a single computing component with two or more independent actual processing units (called "cores"), which are the units that read and execute program instructions. The instructions are ordinary CPU instructions such as add, move data, and branch, but the multiple cores can run multiple instructions at the same time, increasing overall speed for programs amenable to parallel computing. Manufacturers typically integrate the cores onto a single integrated circuit die (known as a chip multiprocessor or CMP), or onto multiple dies in a single chip package.
Processor threads: Hyper-threading was Intels first attempt to bring parallel computation to consumer PCs. It debuted on desktop CPUs with the Pentium 4 HT back in 2002. The original Pentium 4 had just a single CPU core, so it could only do one thing at a time - but hyper-threading attempted to make up for that.
System bus data transfer rate:
Processor 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.).
Processor socket: In computer hardware, a CPU socket or CPU slot comprises one or more mechanical components providing mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows for placing and replacing the CPU without soldering.
Processor cache type: CPU caches are small pools of memory that store information the CPU is most likely to need next. Which information is loaded into cache depends on sophisticated algorithms and certain assumptions about programming code. The goal of the cache system is to ensure that the CPU has the next bit of data it will need already loaded into cache by the time it goes looking for it (also called a cache hit). A cache miss, on the other hand, means the CPU has to go scampering off to find the data elsewhere. This is where the L2 cache comes into play � while it�s slower, it�s also much larger. Some processors use an inclusive cache design (meaning data stored in the L1 cache is also duplicated in the L2 cache) while others are exclusive (meaning the two caches never share data). If data can�t be found in the L2 cache, the CPU continues down the chain to L3 (typically still on-die), then L4 (if it exists) and main memory (DRAM).
PCI Express configurations: PCI Express, technically Peripheral Component Interconnect Express but often seen abbreviated as PCIe or PCI-E, is a standard type of connection for internal devices in a computer. Generally, PCI Express refers to the actual expansion slots on the motherboard that accept PCIe based expansion cards and to the types of expansion cards themselves. PCI Express has all but replaced AGP and PCI, both of which replaced the oldest widely-used connection type called ISA.

Stepping: Stepping level refers to the introduction or revision of the lithographic photomask or masks within the set of plates that generate the pattern that produces an integrated circuit. The term originated from the name of the equipment ("steppers") that exposes the photoresist to light. Integrated circuits have two primary classes of mask sets, base layers that are used to build the structures that make up the logic such as transistors, and metal layers that connect the logic together.
Intel Core i5-2500 Mobile series
Processor operating modes: The x86 has been extended in many ways throughout its history, remaining mostly backwards compatible while adding execution modes and large extensions to the instruction set. A modern x86 processor can operate in one of four major modes: 16-bit real mode, 16-bit protected mode, 32-bit protected mode, and 64-bit long mode. The primary difference between real and protected mode is in the handling of segments: in real mode the segments directly address memory as 16-byte pages, whereas in protected mode the segments are instead indexes into a descriptor table that contains the physical base and size of the segment. 32-bit protected mode allows paging and virtual memory as well as a 32-bit rather than a 16-bit offset.

ECC supported by processor: Error-correcting code memory (ECC memory) is a type of computer data storage that can detect and correct the most common kinds of internal data corruption. ECC memory is used in most computers where data corruption cannot be tolerated under any circumstances, such as for scientific or financial computing.
Memory Toshiba Tecra R850-14C (PT525E-00H00KGR)
Internal memory: RAM (random access memory) is the place in a computing device where the operating system (OS), application programs and data in current use are kept so they can be quickly reached by the devices processor. RAM is much faster to read from and write to than other kinds of storage in a computer, such as a hard disk drive (HDD), solid-state drive (SSD) or optical drive. Data remains in RAM as long as the computer is running. When the computer is turned off, RAM loses its data. When the computer is turned on again, the OS and other files are once again loaded into RAM, usually from an HDD or SSD.

Display Toshiba Tecra R850-14C (PT525E-00H00KGR)
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.
1366 x 768 pixels
LED backlight: An LED-backlit LCD is a flat panel display which uses LED backlighting instead of the cold cathode fluorescent (CCFL) backlighting used by most other LCDs. LED-backlit LCD TVs use the same TFT LCD (thin film transistor liquid crystal display) technologies as CCFL-backlit LCD TVs. Picture quality is primarily based on TFT LCD technology, independent of backlight type.
Aspect ratio: The aspect ratio of an image describes the proportional relationship between its width and its height. It is commonly expressed as two numbers separated by a colon, as in 16:9. For an x:y aspect ratio, no matter how big or small the image is, if the width is divided into x units of equal length and the height is measured using this same length unit, the height will be measured to be y units.

Networking Toshiba Tecra R850-14C (PT525E-00H00KGR)
Bluetooth: Bluetooth is a radio communication technology that enables low-power, short distance wireless networking between phones, computers and other network devices. Bluetooth technology was designed primarily to support networking of portable consumer devices and peripherals that run on batteries.
3G: 3G is the third generation of wireless technologies. It comes with enhancements over previous wireless technologies, like high-speed transmission, advanced multimedia access, and global roaming. 3G is mostly used with mobile phones and handsets as a means to connect the phone to the Internet or other IP networks in order to make voice and video calls, to download and upload data and to surf the net.
Wi-Fi: Wi-Fi is the name of a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. A common misconception is that the term Wi-Fi is short for "wireless fidelity," however this is not the case. Wi-Fi is simply a trademarked phrase that means IEEE 802.11x.
Wi-Fi standards: There are a lot of different types of Wi-Fi standards used by routers and laptops, and to make matters worse, devices don’t typically complain when a sub-optimal Wi-Fi connection is made because of mis-matched Wi-Fi standards. You’ll only notice an issue when the speed and reliability of the connection isn’t as solid as you’d expected. You’ll need to investigate the problem yourself to fix it – and that means knowing a thing or two about Wi-Fi standards.

DVI port: Short for Digital Visual Interface, DVI is a video display interface. It was developed to be an industry standard for transmitting digital video content to display devices at resolutions as high as 2560 x 1600. Common devices that utilize the DVI connection are computer monitors and projectors. DVI can even be used with some TVs, although HDMI is more common as only some DVI cables can transmit audio signals. The DVI connector (shown below) may have one of three names depending on the signals it supports: DVI-A (analog only), DVI-D (digital only), or DVI-I (both digital and analog).
Ethernet LAN (RJ-45) ports quantity: Registered Jack 45 (RJ45) is a standard type of physical connector for network cables. RJ45 connectors are most commonly seen with Ethernet cables and networks. Modern Ethernet cables feature small plastic plugs on each end that are inserted into RJ45 jacks of Ethernet devices. The term "plug" technically refers to the cable or "male" end of the connection while the term "jack" refers to the port or "female" end.
S/PDIF out port: SPDIF, also written as S/PDIF, stands for Sony/Phillips Digital Interface, and is an interface to transmit digital audio. In this tutorial, we will explain everything you need to know about this interface, including when and how to use it.
ExpressCard slot: The Expresscard module is a new technology that slots into a computer system to allow the addition of hardware capabilities. The Expresscard was introduced by the Personal Computer Memory Card International Association (PCMCIA) in 2003 and is a thinner, lighter and faster modular expansion for users of desktop and notebook computers. Hardware capabilities such as extra memory, wired and wireless communication tools and security devices can be added by inserting these modules into the system.
