Low-level software that runs when you first start your computer. Handles booting the OS.
How much data you can send over a connection in a given time. ISPs state speeds in Mbps.
A spare copy of important data in case the original is lost or damaged. Backup to an external drive or cloud storage.
Attempting to guess a password by systematically trying every possible combination of characters.
The number of bits (data) processed per second. Higher bit rates mean better quality but larger files.
The smallest unit of data. It’s either a 1 or a 0, corresponding to an electrical switch being on or off.
8 bits lumped together. Represents a single character, like the letter ‘A’ or a dollar sign.
Data that’s too huge and complex for traditional databases. Requires special tools to store and analyze.
A crash so bad, Windows can’t recover. Note the error message and look it up later. Then take a deep breath and reboot.
I can’t stress this enough. Keep copies of important data on an external drive or in the cloud. One day, you’ll be glad you did.
'Bitwise method' usually refers to 'bitwise operation,' a low-level computational method that performs logical or shift operations on each binary digit of integers. It is not an independent 'number system' or 'numeral system' (the latter is often mistakenly called 'bitwise counting method').
The "bitwise method" usually refers to "bitwise operations," which are low-level calculations that perform logic or shift operations on the binary bits of integers. It's not an independent "counting system" or "number base" (the latter is often mistakenly called "bitwise counting method").
Bayes' Theorem is a core formula in probability theory that describes the relationship between conditional probabilities. Its essence is using new evidence to dynamically update your initial (prior) belief about a hypothesis, which gives you the updated (posterior) probability. This theorem isn't just the foundation of Bayesian inference in statistics—it’s also widely used in areas like machine learning, medical diagnosis, and spam filtering.
Binary is a method of counting using just the digits 0 and 1, with the rule of carrying over when reaching two. Computers basically operate using this system.
The binomial distribution in statistics is a tool used to calculate the probability of a certain number of successes in a fixed number of trials, like how many times a coin will land heads up if you flip it 10 times. It requires that each trial has only two possible outcomes (success or failure), and that the probability of success is the same for each trial.
Looking down from a high place is often used to describe observing things below from above, like when a house is built on a small hill overlooking a river.
Balance equations are mainly used to describe the mathematical expressions of objects being in force balance or chemical reaction equilibrium. In mechanics, the most common case is when the resultant force and the resultant moment are zero. In physical mechanics, they are used to calculate unknown forces on structures; in chemistry, they describe the concentration relationships when a reaction reaches stability.
Biologists are scientists who study life phenomena, and they are divided into fields like zoology, botany, and microbiology.
It's a chart that uses the height or length of bars with the same width to represent the amount of data. Bar charts can be horizontal or vertical, and when vertical, they're also called column charts. Besides that, there are different types of bar charts, like simple bar charts and stacked bar charts.
The bell curve, also called the normal distribution curve, normal curve, or Gaussian distribution, is a graph used in statistics to describe a normal distribution.
The best-fit line is a straight line found using mathematical methods (like the least squares method) that best represents the trend of a set of data points, minimizing the sum of the squared errors from all the data points to the line.
