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).

The turbo boost is an automatic, managed accelleration of the processor when one of the cores is overloaded.

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

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

The type of internal memory such as RAM, GDDR5.

The frequency at which the memory (e.g. RAM) runs.

Number and type of memory expansion slots, including connector and memory module descriptions.

The slots and size of the memory for the CPU.

The maximum internal memory which is available in the product.

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

Used for the storage of data e.g. HDD (hard disk drive), SSD (solid-state drive).

"Graphic adapter" is the hardware that produces images on a display. "On-board" means that the graphics adapter is intergrated inside the motherboard.

The device contains speaker(s) to produce sound.

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

Connection of this device is done via Wi-Fi in a high standard.

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.

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.

The type of bluetooth technology in the product e.g. Bluetooth Smart (v4.0).

Type of antenna, also known an aerial, e.g. external, internal.

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 DisplayPorts. A DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA). The interface is primarily used to connect a video source to a display device such as a computer monitor, though it can also be used to carry audio, USB, and other forms of data.
