Standard cubic centimeters per minute (sccm or cm³/min) is a unit of measurement used to quantify the flow rate of gases. It indicates the volume of gas (in cubic centimeters) that passes through a specific point in a system per minute under standardized conditions, typically at standard temperature and pressure (STP). Standard conditions often refer to a temperature of 0 degrees Celsius (273.15 K) and a pressure of 1 atmosphere (101.325 kPa).
Standard litre per minute (SLPM or L/min) is a unit of measurement commonly used in various scientific and engineering fields to measure gas flow rates. It indicates the volume of gas flowing per minute at "standard" conditions of temperature and pressure. The "standard" conditions can vary based on context but are often considered to be at a temperature of 0 degrees Celsius (273.15 K) and a pressure of 1 atmosphere (101.325 kPa).
Binary prefixes are a set of unit prefixes used in computing and data storage to express quantities that are powers of two. They are an extension of the standard metric prefixes (like kilo, mega, giga) that are based on powers of ten. In the binary system, however, quantities are often expressed as powers of two, which is more relevant in contexts such as computer memory and storage.
"Flashes per minute" generally refers to the frequency or rate at which a light, such as a strobe light or a warning light, emits flashes. This measurement is often used in various contexts, including emergency vehicle lights, photography (with flash units), and certain visual displays. For example: 1. **Emergency lights**: In emergency vehicles, lights may flash at specific rates for increased visibility. A common flash rate might be 60 flashes per minute (1 flash per second).
In networking, a "frame" refers to a data packet or unit of data that is transmitted over a network at the data link layer of the OSI (Open Systems Interconnection) model. Frames are used to encapsulate network layer packets, adding necessary information for routing and delivery over physical networks. ### Key Components of a Frame: 1. **Header**: Contains control information used by network devices to process or route the frame.
A gigabyte (GB) is a unit of digital information storage that is commonly used to measure the size of data, storage capacity of devices, and memory in computers and other electronic devices. 1. **Definition**: In terms of binary calculations, one gigabyte is equal to \(2^{30}\) bytes, which is 1,073,741,824 bytes. In decimal terms, it is often defined as 1 billion bytes (1,000,000,000 bytes).
The Hartley (symbol: Hart) is a unit of information used in the field of information theory. It is named after the American engineer Ralph Hartley. The Hartley quantifies the amount of information produced by a source of data and is based on the logarithmic measure of possibilities. Specifically, one Hartley is defined as the amount of information that is obtained when a choice is made from among \(10\) equally likely alternatives.
Revolutions per minute (RPM) is a unit of rotational speed that indicates the number of complete rotations an object makes around a fixed axis in one minute. It is commonly used to measure the speed of engines, motors, and other rotating machinery. For example, if a motor is said to run at 3,000 RPM, it means that the motor completes 3,000 full rotations in one minute.
Wavenumber is a measure of the number of wavelengths per unit distance and is used in various fields such as physics, chemistry, and optics. It is defined as the reciprocal of the wavelength and is usually expressed in units of reciprocal length, such as inverse meters (m⁻¹).
Cable length refers to the physical length of a cable, which can vary depending on its application and type. This measurement is essential in various fields, such as telecommunications, electrical engineering, and networking. The length of a cable can influence its performance, signal strength, and overall functionality. In contexts like electrical wiring, longer cable lengths may lead to voltage drop, while in networking, longer data cables may result in increased latency or loss of signal quality.
Canna, often abbreviated as "can," is a unit of measurement used to quantify the amount of cannabis. It may refer to both weight and volume, depending on the context. While there isn't a standardized measurement universally recognized, "canna" is typically used in informal settings or in specific regions. If you're referring to a more formal measurement system, cannabis is commonly measured in grams or ounces. In legal markets, these measurements are used for sales and regulatory purposes.
SOXS is an acronym that can refer to different things depending on the context. Here are a couple of common usages: 1. **SOXS (Soxhlet Extraction)**: In scientific and analytical contexts, SOXS may refer to the Soxhlet extraction method, which is used to extract lipids or other compounds from a solid sample through continuous solvent extraction.
The effective data transfer rate, often referred to as throughput, is the actual speed at which data is successfully transmitted over a network or communication medium. This measurement takes into account various factors that can affect the data transfer, such as: 1. **Network Congestion**: Higher traffic can slow down data transmission rates. 2. **Protocol Overhead**: Communication protocols (e.g.
A kilobyte (KB) is a unit of digital information storage that is commonly used to measure the size of files and data. The term is derived from the prefix "kilo-", which means one thousand. However, in the context of computer science, it can refer to either: 1. **Decimal Kilobyte (KB)**: In this usage, 1 kilobyte is equal to 1,000 bytes.
A binary code is a system of representing text or computer processor instructions using the binary number system, which uses only two symbols: typically 0 and 1. Here's a basic overview of different types of binary codes: 1. **ASCII (American Standard Code for Information Interchange)**: - A character encoding standard that represents text in computers. Each character is represented by a 7-bit binary number.
IEEE 1541-2002 is a standard developed by the Institute of Electrical and Electronics Engineers (IEEE) that provides guidelines for the definitions and abbreviations of terms used in electrical engineering, specifically in the area of power and energy. The standard serves to promote clarity and consistency in terminology across the electrical and electronic fields, making it easier for professionals and researchers to communicate effectively.
JEDEC, which stands for the Joint Electron Device Engineering Council, is an organization that sets standards for the semiconductor industry, including memory devices. JEDEC memory standards define the specifications, performance characteristics, and operational protocols for various types of memory, ensuring compatibility and reliability across devices manufactured by different companies.
The term "Ice-type model" could refer to a few different contexts, depending on the field. However, without specific context, it isn't clear which one you are referring to. Below are a few possibilities: 1. **Gaming Context (Pokémon)**: In the Pokémon series, Ice-type refers to a classification of Pokémon that have ice-based abilities. They are known for their resistance to certain types of attacks and their effectiveness against others.
A "Nat" is a unit of information used in the field of information theory. It is derived from natural logarithms and is sometimes referred to as "nats" in the plural form. The nat measures information content based on the natural logarithm (base \( e \)).
The term "nibble" can refer to a few different things depending on the context: 1. **Computing**: In the realm of computer science, a "nibble" is a unit of digital information that consists of four bits. Since a byte is typically made up of eight bits, a nibble can represent 16 different values (from 0 to 15 in decimal).

Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
