PTA0157-28

Size of the display for this product, measured diagonally, usually in inches.

The number of distinct pixels in each dimension that can be displayed. It is usually quoted as width × height, with the units in pixels: for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels. The higher the number of pixels, the sharper the image.

A screen of a laptop, smartphone, etc., that responds to touch so you can control the interface using your fingers.

Brightness is the amount of radiating light emitted from the screen. The brightness rating is measured in candellas per square meter, commonly known as 'nits'.

The difference in light intensity between the brightest white and the darkest black.

Maximum horizontal angle at which a display can be viewed with acceptable visual performance.

Maximum vertical angle at which a display can be viewed with acceptable visual performance.

The response time is the time difference between the moment that a source (for example a video card) sends a signal and that equipment (for example a monitor) receives or display the signal. (Used abbreviations: R/F = Rise and Fall.)

The aspect ratio is the ratio of the width of a shape to its height. For example, 4:3 is common for standard displays and 16:9 is the ratio for Widescreen TV.

The speed that the microprocessor executes each instruction or each vibration of the clock. The CPU requires a fixed number of clock ticks, or cycles, to execute each instruction. The faster the clocks rate, the faster the CPU, or the faster it can execute instructions. Clock Speeds are usually determined in MHz, 1 MHz representing 1 million cycles per second, or in GHz, 1 GHz representing 1 thousand million cycles per second. The higher the CPU speed, the better a computer will perform.

The manufacturer that produced the processor.

A family of processors is a group of processors produced by one company over a short period of time e.g. Intel Pentium processors.

The model number for the processor in a computer.

The number of central processing units ('cores') in a processor. Some processors have 1 core, others have 2 (e.g. Intel Core Duo) or more (e.g. the Intel Xeon E7-2850 has 10 cores).

A computer's memory which is directly accessible to the CPU.

The total amount of data that can be stored on the device.

What the casing of the product is made of.

The device includes a card reader e.g. a card reader in the disk bay of a computer or thin client to permit log-on using smart/pin cards.

Types of memory cards which can be used with this product.

An Ethernet LAN (Local Area Network) interface is present, for a wired conection via a cable.

The different speed levels of the Ethernet LAN connection.

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.

Popular technology that allows an electronic device to exchange data or connect to the internet wirelessly using radio waves.

The type of wireless local area network (LAN). It can be ad-hoc, where units in a network communicate peer-to-peer, or Infrastructure, where units communicate with each other via an access point  A LAN interconnects computers in a small area e.g. home, school or office.

Number of Ethernet LAN (RJ-45) ports (connecting interfaces) in the device.  Ethernet LAN (RJ-45) ports allow a computer to connect to the ethernet.

Number of USB 2.0 ports (connecting interfaces) in the device. USB 2.0 was released in April 2000 (now called "Hi-Speed"), adding higher maximum signaling rate of 480 Mbit/s (effective throughput up to 35 MB/s or 280 Mbit/s), USB 2.0 ports are usually black.

The number of sockets (ports) for RS-232. An RS-232 serial port was once a standard feature of a personal computer, used for connections to modems, printers, mice, data storage, uninterruptible power supplies, and other peripheral devices. Now it has been largely replaced by USB and other ports.

The colour e.g. red, blue, green, black, white.

Type of operating system on a device e.g. IOS on Apple devices, Android for mobile devices.

The voltage of the AC electricity that is inputted into the product.

Amount of power consumed by this model, often expressed in watts (W). Typical values that manufacturers give are power consumption when off, standby/suspended mode, typical use, maximum usage.

The minimum and maximum temperatures at which the product can be safely operated.

The minimum and maximum temperatures at which the product can be safely stored.

The measurement or extent of something from side to side.

The distance from the front to the back of something.

The measurement of the product from head to foot or from base to top.

Weight of the product without packaging (net weight). If possible, the net weight is given including standard accessories and supplies. Please note that sometimes the manufacturer leaves out the weight of accessories and/or supplies.

The distance from one side of the packaging to the other.

The distance from the front to the back of the packaging.

The distance from the top to the bottom of the packaging.
