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.

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

The maximum internal memory which is available in the product.

The type of internal memory such as RAM, GDDR5.

The maximum storage capacity of the hard disk, usually measured in bytes e.g. GB.

The way that a hard disk drive (HDD) is connected to the rest of the computer through a 'bus' such as ATA or SCSI.

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.

Number of VGA (D-Sub) ports (connecting interfaces) in the device. The VGA (D-Sub) connector is a 15 pin connector between a computer and a monitor. It was first introduced in 1987 by IBM.

The number of PS/2 connectors for keyboards and mice. Its name comes from the IBM Personal System/2.

Number of IEEE 1394/FireWire ports (connecting interfaces) in the device. The IEEE 1394 interface is a serial bus interface standard for high-speed communications and isochronous real-time data transfer. It was developed in the late 1980s and early 1990s by Apple, who called it FireWire. The 1394 interface is comparable to USB though USB has more market share. Apple first included FireWire in some of its 1999 models, and most Apple computers since the year 2000 have included FireWire ports, though, as of 2013, only the 800 version (IEEE-1394b).

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.

The socket where a microphone is connected to the device.

Number of sockets /ports where headphones are connected.

The number of serial ports in a computer or peripheral. A serial port is a serial communication physical interface through which information transfers in or out one bit at a time. The term "serial port" usually identifies hardware more or less compliant to the RS-232 standard, intended to interface with a modem or with a similar communication device. In modern computers and peripherals, serial ports have largely been replaced by USBs and other interfaces.

The number of parallel ports. Parallel ports, also known as printer ports, are a type of interface found on computers (personal and otherwise) for connecting peripherals. In computing, a parallel port is a parallel communication physical interface. Parallel ports were common in the 1980s and '90s (mostly conforming to industry standard IEEE 1284) but are now being replaced by USBs and other ports.

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

The way in which the product is powered e.g. rechargeable battery, mains electricity connected via a plug and cable.

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.
