Dell OptiPlex 3060 Small Form Factor Desktop Computer

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 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.

Mechanical component(s) that provides mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows the processor to be replaced without soldering.

A bus is a communication system that transfers data between components inside a computer, or between computers. The system bus rate is the speed at which data is transferred in this communication system.

The process which is performed by the processor e.g. CPU (Central Processing Unit).

Operating modes for the processors that place restrictions on the type and scope of operations for certain processes run by the CPU. This design allows the operating system to run with more privileges than application software.

Number of processors in the product.

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.

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

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).

An optical drive uses laser to read optical discs such as CDs, DVDs and Blu-Ray. Some types of optical drive are: CD ROM drive, CR-RW (CD writer) drive, DVD-ROM.

Amount of storage drives built into the device.

The number of hard drives built into the device.

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

Graphics hardware which is built into the motherboard or CPU, as opposed to a separate graphics adapter (video card). On-board graphics uses CPU and RAM for graphics processing.

A graphics adapter (often known as a video card) generates images for a display. A discrete graphics adapter plugs into the motherboard, and usually produces much better graphics than an integrated graphics adapter. There are various models of discrete graphics adapters.

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

The feature may not be available on all computing systems. Functionality, performance, and other benefits of this feature may vary depending on system configuration.

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.

Type of cable technology performance.

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

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.

Digital Visual Interface (DVI) is a video display interface to connect a video source to a display device, such as a computer monitor.

The number of sockets (ports) for HDMI connections. HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transferring uncompressed video data and compressed/uncompressed digital audio data from a HDMI-compliant device (“the source device”) to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for existing analog video standards.

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.

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.
