Broadband in telecommunications is a term used to refer to any technology that utilizes a “broad” band of frequencies to transmit data.
When used in the context of internet services, broadband refers to practically any technology newer than dial-up internet. These include technologies such as DSL (Digital Subscriber Line), Cable, Fiber Optics, Wireless (Mobile Broadband), Satellite, or BPL (Broadband over PowerLines). Currently, there are no official specifications that define broadband.
Coil whine is a phenomenon in electronics where electromagnetic coils within an electrical circuit exhibit a high pitched sound as electricity passes through the circuit. Typically, this is most often heard in high performance computer components such as graphics cards and processors, but is actually very common in other electronics such as fluorescent light ballasts.
While annoying and sometimes a bit scary, coil whine is simply a result of sounds made as electricity passes through electrical coils. This is typically a result of poor engineering as these sounds can be minimized by utilizing coil dampening techniques. Rest assured however, no damage will occur to your system.
The CPU, also known as the Central Processing Unit, is one of the core components in a computer that includes all the logic needed to process programming instructions. CPUs are often also referred to as processor or microprocessor. Some people erroneously refer to the entire computer as the CPU.
CSV, or Comma-Separated Values, is tabular data expressed in plain text separated by commas, and is most commonly found in a CSV file. CSV files are typically created by a computer program or database in order to export its data to another computer program or database.
The reason why CSV files are so common is because CSV files are simply plain text and can easily be read by any application such as Microsoft Excel.

CUDA cores when used in the context of graphics is simply the name for the processors within the Nvidia Graphics Processing Unit (GPU). Generally, Nvidia GPUs house thousands of CUDA cores which are designed to process visual data quickly in parallel in order to generate the pixels that make up an image on a screen. Thus, the more CUDA cores, theoretically the faster the performance of a GPU. However, CUDA cores may only be used for comparison between graphics cards of the same architecture as CUDA cores in different GPU architectures perform differently. The equivalent to CUDA cores on AMD (formerly ATI) GPUs is Stream Processors.
The CUDA from CUDA cores comes from Nvidia’s Compute Unified Device Architecture, which is a parallel computing platform and API (Application Programming Interface). This technology was designed to allow developers to take advantage of the processing capabilities within Nvidia GPUs for general purpose use. CUDA is still widely used today to accelerate a variety of workloads such as 3D modeling, video rendering, simulations, machine learning, and more.
DFS, when used in the context of wireless networking, stands for Dynamic Frequency Selection.
DFS is a spectrum sharing technology which allows Wi-Fi to operate in 5GHz frequency bands allocated to radar systems without causing interference. In order to do this, devices that support DFS will continually monitor the frequency for potential radar signals. If a radar signal is detected, the device will leave the frequency, switch to another channel, and stay away from the channel with a radar signal for a set period of time.
DFS channels include 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136 and 140.
Devices that support DFS include the Ubiquiti UniFi AP AC PRO.
DHCP, or Dynamic Host Configuration Protocol, is a technology designed to allow clients to request a lease of an IP address from a pool (also know as a table) of available IPs at the time of the request. DHCP can also supply other information such as the subnet mask and default gateway.
The primary use of DHCP is to simplify the work of the network admin. It offloads the work of having to manually assign IPs and prevents IP conflicts among clients. It is an essential feature in both small home networks where consumers are unfamiliar with complicated network setup and large networks that have hundreds and thousands of clients.
FC SAN, or Fiber Channel Storage Area Network, is a type of SAN which uses fiber channel to connect servers and the SAN. Fiber channel is an ultra high speed technology designed for transmitting data at data up to 128Gb/s.
Hysteresis in mechanical keyswitches occurs when the reset point on the switch is higher than the actuation point. For example, the Cherry MX Blue switch actuates at around 2.5mm from the top, but its reset point is only 1.5mm from the top. This means that the user would have to release the key beyond the actuation point before another keypress can be registered. Hysteresis is one of the main reason why many gamers prefer linear switches since the reset point is almost exactly where the actuation point is.
IOPS, or Input/Output Operations per Second, is a storage performance metric which measures how many reads and writes are occurring every second. As smaller files take less time to transfer compared to larger files, the IOPS metric is typically used to measure transfers of 4K or 8K file sizes. Larger filesize reads and writes such as 128K, 512K and larger are typically measured by throughput such as MB/s (Megabytes Per Second) or GB/s (Gigabytes Per Second).
