Recursion

2025-05-23 10:23:55 UTC

Recursion - method to define a set through itself using basic cases.

For example, when we go to WB resources we are finding needed things and sometimes we use function to see similar things and then WB open a new list of things.

On the last lesson of "Algorithms and data structures" we did function to compute factorial using recursion.

Epigenetics

2025-05-23 10:29:16 UTC

The study of heritable changes in gene expression that do not involve alterations to the DNA sequence itself, often influenced by environmental factors. Plays a role in bioengineering and medicine.

Spintronics

2025-05-23 10:29:40 UTC

A branch of electronics that exploits the intrinsic spin of electrons (not just charge) to store and process information, enabling ultra-low-power devices.

Metamaterials

2025-05-23 10:30:07 UTC

Artificially engineered materials with properties not found in nature, such as negative refractive index, used for invisibility cloaks or superlenses.

2025-05-23 10:30:28 UTC

Operating system

an essential software that manages a computer's hardware and software, acting as an interface.

OS Windows

Assembly line

2025-05-23 10:30:39 UTC

A line of machines and workers in a factory that a product moves along while it is being built or produced. Each machine or worker performs a particular job that must be finished before the product moves to the next position in the line.

In addition to eliminating the need for skilled workers, the assembly line also reduced the monitoring costs to zero.

Topological Quantum Computing

2025-05-23 10:31:16 UTC

A theoretical approach to quantum computing where qubits are protected from decoherence by encoding information in topological states of matter (e.g., anyons).

Lathe

2025-05-23 10:34:29 UTC

A machine for changing the shape of a piece of wood, metal, etc. that works by turning the material while a sharp tool is pressed against it.

He wrapped metal wire around cylindrical bars of soft iron by means of a lathe.

Screw

2025-05-23 10:37:26 UTC

A thin, pointed piece of metal with a raised edge twisting round along its length and a flat top with a cut in it, used to join things together, especially pieces of wood

Screws are used for fastening metal parts together

2025-05-23 10:38:59 UTC

Railway

a system of transportation that uses tracks and trains to move people and goods.

I get to Sochi by railways.

Resistance (electrical)

2025-05-23 10:39:20 UTC

A value which characterize ability of a cable to resist the conduction of electricity. Usually measured in ohms and derived units: kiloohms, megaohms and gigaohms.

Firewall

russianbear39157 — 2025-05-23 11:06:29 UTC

is a network security system that monitors and controls incoming and outgoing network traffic based on configurable security rules. A firewall typically establishes a barrier between a trusted network and an untrusted network, such as the Internet or between several VLANs.

Chipset

russianbear39157 — 2025-05-23 11:06:39 UTC

A chipset is a collection of electronic components on a motherboard that manages the data flow between the CPU, GPU, RAM, storage, and peripherals. It acts as the traffic controller of the motherboard, facilitating communication between all connected components. Experts often refer to it as the "glue" of the motherboard.

Pointer

russianbear39157 — 2025-05-23 11:06:45 UTC

is an object in many programming languages that stores a memory address. This can be that of another value located in computer memory, or in some cases, that of memory-mapped computer hardware.
