Refers to a computer’s physical size and shape, like a laptop vs a desktop tower.
A virtual container for organizing files. Folders can contain other folders for a nested hierarchy.
Permanent software programmed into a read-only memory on devices like routers and IoT gadgets.
The part after the dot in a filename, like .jpg or .mp3, that tells you its format.
When files get scattered around a drive. Can slow performance. Defragging fixes this. (Not applicable to SSDs )
Monitors traffic between networks to block suspicious activity. Can be hardware or software.
How many individual images make up one second of a video? Films traditionally use 24FPS.
Low storage and memory can lead to poor performance. Try uninstalling apps you don’t use or moving files to the cloud.
Every few months, clear out old files and organize the rest into folders. Future you will thank past you.
The Fibonacci sequence is a series where each term from the third one onward equals the sum of the two preceding terms. A common sequence is 0, 1, 1, 2, 3, 5, 8… It was introduced by the Italian mathematician Fibonacci in 1202 and is famous because of the rabbit reproduction problem. It's also called the 'rabbit sequence' or the 'golden ratio sequence'.
Generally, if A and B represent two polynomials, and B contains a variable, then the expression A / B is called a rational expression, where A is called the numerator and B is called the denominator.
In math, a fraction refers to dividing the unit '1' into several equal parts, representing one or more of those parts.
Fraction multiplication is a way of doing math. You multiply the numerators together and the denominators together. If you can simplify, simplify first. You can't multiply the numerator by the denominator.
Fraction calculations mainly include the four basic operations: addition, subtraction, multiplication, and division, and each operation has clear rules.
Fraction subtraction mainly depends on whether the denominators are the same. If they are, just subtract the numerators. If they're different, find a common denominator first, then subtract, and simplify the result if possible.
A fraction line is the horizontal line drawn between the numerator and the denominator. Sometimes, this line can also appear as a slash '/', with the numerator on the left and the denominator on the right.
Fractal is a geometric term officially proposed by mathematician Benoît B. Mandelbrot in 1975. It refers to a complex geometric shape that has self-similarity and usually a non-integer (fractional) dimension. It's considered a mathematical language for describing irregular forms in nature and is also called 'the geometry of nature.'
Fractal geometry is a branch of geometry that studies irregular geometric shapes. Its main focus is on describing and studying complex structures that are self-similar (parts resemble the whole) and have non-integer dimensions, which is why it’s often called 'the geometry of nature'.
In math class, when solving a quadratic equation, you can directly plug the coefficients into the quadratic formula to get the result. This method is called the formula method and is where many people first encounter formulas. But the meaning of a formula goes far beyond that; it's a universal tool for expressing patterns and simplifying calculations across different fields. Whether in scientific computations or everyday office work, you can see formulas in action.
In a process of change, if there are two variables x and y, and for every value of x there is a unique value of y corresponding to it, then y is a function of x.
Financial applications usually have two layers of meaning: one is the use of fintech in areas like banking, investment, and risk management, and the other is the financial software or apps that everyday users use. Right now, financial applications are rapidly evolving from digital to intelligent, with AI agents and blockchain technologies becoming core drivers.
Force is the effect that objects have on each other. It can't exist independently of an object; whenever there is an object exerting a force, there must be an object receiving it.
Frequency is just the number of times a certain data point or event occurs, and it's the most basic counting measure in statistics.
The core of the fundamental theorem of calculus is the Newton-Leibniz formula.
Factoring is all about turning a polynomial into a product of several polynomials. It's the reverse of polynomial multiplication, and the main goal is to simplify things.
