VAIO FZ21E

Processor speed in Mhz. Often the clock speed is expressed by a manufacturer in GHz (1 GHz = 1000 MHz). The clock rate is the fundamental rate in cycles per second (measured in hertz) at which a computer performs its most basic operations such as adding two numbers. There are more factors, like internal memory size, that influence a computer's actual response time.

The processor serie to which the processor belongs.

Processor is the central unit in a computer containing the logic circuitry that performs the instructions of a computer's programs.

Speed of the processor's Front Side Bus (FSB) in megahertz (1 million Herz). The FSB is the bus that transfers data between the CPU and the northbridge of the Motherboard. The maximum theoretical bandwidth of the FSB is determined by the product of its width, its clock frequency and the number of data transfers it performs per clock tick.

Chipset for this configuration; expressed as manufacturer and coined name

The CPU cache (Level 2 in megabyte) is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations.

Total storage capacity in Gigabyte (1 billion bytes).

The rotational speed of a hard disk expressed in rotations per minute. The faster the better.

Size of the display for this product; expressed in inches diagonal

The display technology. Flat screen technologies like Liquid Cristal Display (LCD) and Thin Film Transistor (TFT) active matrix technology are the trend. In TV technologies one can notice FST (Flat Screen Tube) technology, and ARASC (Anti Reflexion, Anti Static Coating) or AGARAS (Anti-Glare ARASC) or simply AGC (anti-glare coating). The old tv and screen technology CRT means Cathodic Ray Tube. MLA = Micro Lens Array. p-Si=Polycrystalline Silicon. a-Si=Amorphous Silicon.

Resolution of the display for the system

The amount of memory measured in megabytes installed in the system's hardware

Describe how memory is plugged on the motherboard

Type of the optical drive

MegaPixels: The number (in millions) of light-sensitive picture elements, or pixels, actually used by the camera's image sensor (CCD) to record light, and which are reflected to the final number of recorded pixels stored on the memory card.

Type of cable technology performance; including the fiber or cable type

Bluetooth is a low-power radio technology developed to replace the cables and wires currently used to link or connect electronic devices such as personal computers, printers, and a wide variety of handheld devices including mobile phones. Because it uses radio-wave connectivity, a Bluetooth-enabled device has a constant, established connection to whatever browser it uses. This saves the user the trouble of logging on to check for emails or news updates, for example.

Description of TV Out port

USB 2.0 ports have a data transmission speed of 480 Mbps, and are backwards compatible with USB 1.1 ports. You can connect all kinds of peripheral devices to them.

A data port that uses infra-red data association (irDA) as the standard for wireless communications between computer and mobile phone devices. For example, to update the phone list on your irDA-enabled PC, you would line up the infra-red ports on each device and then transfer the phone information to your PC. This is a wireless transfer, so you don't need a cable or extra software.

Weight of the product without packaging (nett weight). If possible, the nett weight is given including standard accessories and supplies. Please, note that sometimes the manufacturer is giving a too commercial interpretation of product weight, by leaving out the weight of accessories and/or supplies.
