Display Toshiba Satellite U945-ST4N01
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.
Display Screen Type: A display screen made with TFT (thin-film transistor) technology is a liquid crystal display (LCD), common in notebook and laptop computers, that has a transistor for each pixel (that is, for each of the tiny elements that control the illumination of your display). Having a transistor at each pixel means that the current that triggers pixel illumination can be smaller and therefore can be switched on and off more quickly.
Active Matrix TFT Color LCD
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.
Screen Mode: High Definition is largely a fluid term, taking the shape of a lot of different containers, with the only real meaning being something with a significantly increased picture quality and clarity based on the resolution of the monitor in question.
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
Backlight Technology: 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.

Graphics Memory Capacity: 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.
Up to 1.63 GB
Graphics Memory Technology:
Graphics Memory Accessibility: 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. A dedicated, or discrete, GPU has its own independent source of video memory, leaving the RAM your system uses untouched.
Hard Drive Toshiba Satellite U945-ST4N01
Storage 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 Interface: Hard disk drives are accessed over one of a number of bus types, including as of 2011 parallel ATA (PATA, also called IDE or EIDE; described before the introduction of SATA as ATA), Serial ATA (SATA), SCSI, Serial Attached SCSI (SAS), and Fibre Channel. Bridge circuitry is sometimes used to connect hard disk drives to buses with which they cannot communicate natively, such as IEEE 1394, USB, SCSI and Thunderbolt.
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.

Optical Drive Type: In computing, an optical disc drive (ODD) is a disk drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs. Some drives can only read from certain discs, but recent drives can both read and record, also called burners or writers. Compact disks, DVDs, and Blu-ray disks are common types of optical media which can be read and recorded by such drives. Optical disc drives that are no longer in production include CD-ROM drive, CD writer drive, and combo (CD-RW/DVD-ROM) drive. As of 2015, DVD writer drive is the most common for desktop PCs and laptops. There are also the DVD-ROM drive, BD-ROM drive, Blu-ray Disc combo (BD-ROM/DVD±RW/CD-RW) drive, and Blu-ray Disc writer drive.

Memory Card Supported: A memory card can be inserted into this slot and used to store.
Secure Digital (SD) Card, Secure Digital High Capacity (SDHC), Secure Digital Extended Capacity (SDXC), miniSD Card, microSD Card, MultiMediaCard (MMC)
Memory Technology: Research and development efforts have recently shifted towards semiconductor memory technologies that not only complement the existing memory and storage hierarchy but also reduce the distinction between memory (fast, expensive, volatile) and storage (slow, inexpensive, nonvolatile).
Number of Total Memory Slots: Sometimes the best way to determine how many memory slots are in the computer and how many are available for upgrade is to open the computer and examine the computer motherboard.
Memory Card Reader: A memory card reader is a device for accessing the data on a memory card such as a CompactFlash (CF), Secure Digital (SD) or MultiMediaCard (MMC). Most card readers also offer write capability, and together with the card, this can function as a pen drive.
Network Toshiba Satellite U945-ST4N01
Wireless LAN: A wireless local area network (WLAN) is a wireless computer network that links two or more devices using a wireless distribution method (often spread-spectrum or OFDM radio) within a limited area such as a home, school, computer laboratory, or office building. This gives users the ability to move around within a local coverage area and still be connected to the network, and can provide a connection to the wider Internet. Most modern WLANs are based on IEEE 802.11 standards, marketed under the Wi-Fi brand name.

Ethernet Technology: Ethernet is a family of computer networking technologies for local area networks (LANs) and metropolitan area networks (MANs). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3, and has since been refined to support higher bit rates and longer link distances. Over time, Ethernet has largely replaced competing wired LAN technologies such as token ring, FDDI, and ARCNET. The primary alternative for contemporary LANs is not a wired standard, but instead a wireless LAN standardized as IEEE 802.11 and also known as Wi-Fi.
Bluetooth Standard: 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.

Processor Toshiba Satellite U945-ST4N01
Processor Type:A mobile processor is found in mobile computers and cellphones. A CPU chip is designed for portable computers, it is typically housed in a smaller chip package, but more importantly, in order to run cooler, it uses lower voltages than its desktop counterpart and has more "sleep mode" capability. A mobile processor can be throttled down to different power levels or sections of the chip can be turned off entirely when not in use. Further, the clock frequency may be stepped down under low processor loads. This stepping down conserves power and prolongs battery life.
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.
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.
Dual-core (2 Core)
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.).
Chipset Model: Chipset is the name given to the set of chips (hence its name) used on a motherboard.
Software Toshiba Satellite U945-ST4N01
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.
Operating System Architecture: Operating systems evolve over time, but that evolution is frequently in terms of their architecture: how they structure functionality relative to protection boundaries.
Input Devices Toshiba Satellite U945-ST4N01
Pointing Device Type: A pointing device is an input interface (specifically a human interface device) that allows a user to input spatial (i.e., continuous and multi-dimensional) data to a computer. CAD systems and graphical user interfaces (GUI) allow the user to control and provide data to the computer using physical gestures by moving a hand-held mouse or similar device across the surface of the physical desktop and activating switches on the mouse. Movements of the pointing device are echoed on the screen by movements of the pointer (or cursor) and other visual changes. Common gestures are point and click and drag and drop.
TouchPad Features: With the rise of laptops and netbooks, the touchpad has become a key input device. Yet, in the Windows environment, working with the touchpad has been a drag more than a delight. While the hardware often is able to perform the same tricks as Apple's touchpads, sometimes drivers don't support its full capabilities or users are simply not aware of the available features. This article shows you how you can discover the true skills of your touchpad.
Battery Toshiba Satellite U945-ST4N01
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.
