Display size or viewable image size or VIS is the physical size of the area where pictures and videos are displayed.

The size of sp4212sl screen is usually described by the length of its diagonal, which is the distance between opposite corners, usually in inches. A display screen made with TFT thin-film transistor technology is a liquid crystal display LCDcommon in notebook and laptop computers, that has a transistor for each pixel that is, for each of sp4221sp 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.

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 wp4221sl High Definition is sp4221ls 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.

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 x, which means 1, horizontal pixels and 1, vertical pixels.

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. The amount of storage on a hard disk, measured in gigabytes and terabytes.

Hard drive capacity is generally measured by the amount sp4212sl data users need to store, which is usually much greater than the space applications take up.

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 RPM and another with RPM, the hard drive with a RPM will be capable of accessing data much faster than the other.

In computing, an optical disc ep4221sl 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 s;4221sl 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. A memory card can be inserted into this slot and used to store.

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, ps4221sl. 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.

Most card readers also offer write capability, and together with the card, this can function as a pen drive. 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. Ethernet is a family of computer networking technologies for local area networks LANs and metropolitan area networks MANs.

Toshiba Satellite C845-SP4221SL – laptop specifications.

It was commercially introduced in and first standardized in as IEEE 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. The clock rate typically refers to the frequency at which a chip like a central processing unit CPUone 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 kHzbut 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. 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 CMPor onto multiple dies in a single chip package.

A CPU cache is a cache used by the 8c45 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 sp4221el data from frequently used v845 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. 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 sp42211sl require an operating system to function. Operating systems evolve over time, but that evolution is frequently in terms of their architecture: A pointing device is an input interface specifically a human interface device that allows a user to input spatial i.

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 cc845 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. With zp4221sl 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 c854 able to perform the same tricks as Sp4221dl touchpads, sometimes drivers don’t ps4221sl 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 zp4221sl touchpad. 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 v845 flow out of the battery to perform work.

The pin VGA connector is found on many video cards, computer monitors, and high definition television sets. On laptop computers or other small devices, a mini-VGA port is sometimes used in place of the full-sized VGA connector.
