Character encoding is the process of assigning numbers to graphical characters, especially the written characters of human language, allowing them to be stored, transmitted, and transformed using digital computers. The numerical values that make up a character encoding are known as "code points" and collectively comprise a "code space", a "code page", or a "character map".

Vecchia RAM a nuclei magnetici da 1,5 Megabit. Nelle SRAM, acronimo di Static Random Access Memory, ovvero RAM statica ogni cella è costituita da un Flip-Flop di tipo D. Le celle sono disposte a matrice e l'accesso avviene specificando la riga e la colonna.. Consentono di mantenere le informazioni per un tempo infinito ma, perdono le informazioni in esse contenute …

靜態隨機存取存储器（Static Random Access Memory，SRAM）是隨機存取存储器的一種。 所謂的「靜態」，是指這種存储器只要保持通電，裡面儲存的数据就可以恆常保持 。 相對之下，動態隨機存取記憶體（DRAM）裡面所儲存的数据就需要週期性地更新。 然而，當電力供應停止時，SRAM儲存的数据還是會消失 ...

In electronics, a flip-flop or latch is a circuit that has two stable states and can be used to store state information – a bistable multivibrator.The circuit can be made to change state by signals applied to one or more control inputs and will have one or two outputs. It is the basic storage element in sequential logic.Flip-flops and latches are fundamental building blocks of digital ...

An in-memory database (IMDB, or main memory database system (MMDB) or memory resident database) is a database management system that primarily relies on main memory for computer data storage.It is contrasted with database management systems that employ a disk storage mechanism. In-memory databases are faster than disk-optimized databases because disk …

The two main types of volatile random-access memory (RAM) are static random-access memory (SRAM) and dynamic random-access memory (DRAM). Bipolar SRAM was invented by Robert Norman at Fairchild Semiconductor in 1963, [9] followed by the development of MOS SRAM by John Schmidt at Fairchild in 1964. [13]

The kernel is a computer program at the core of a computer's operating system and generally has complete control over everything in the system. It is the portion of the operating system code that is always resident in memory and facilitates interactions between hardware and software components. A full kernel controls all hardware resources (e.g. I/O, memory, cryptography) via …

exFAT (Extensible File Allocation Table) is a file system introduced by Microsoft in 2006 and optimized for flash memory such as USB flash drives and SD cards. [5] exFAT was proprietary until 28 August 2019, when Microsoft published its specification. [6]

Magnetoresistive random-access memory (MRAM) is a type of non-volatile random-access memory which stores data in magnetic domains. Developed in the mid-1980s, proponents have argued that magnetoresistive RAM will eventually surpass competing technologies to become a dominant or even universal memory . [2]

In computer science, a trie, also called digital tree or prefix tree, is a type of k-ary search tree, a tree data structure used for locating specific keys from within a set. These keys are most often strings, with links between nodes defined not by the entire key, but by individual characters.In order to access a key (to recover its value, change it, or remove it), the trie is traversed depth ...

La memoria de acceso aleatorio (Random Access Memory, RAM) es una memoria de almacenamiento a corto plazo.El sistema operativo de ordenadores u otros dispositivos utiliza la memoria RAM para almacenar de forma temporal todos los programas y sus procesos de ejecución [1] . En la RAM se cargan todas las instrucciones que ejecuta la unidad central de …

RAM tĩnh - SRAM (Static Random Access Memory) được chế tạo theo công nghệ ECL (dùng trong CMOS và BiCMOS). Mỗi bit nhớ gồm có các cổng logic với 6 transistor MOS. SRAM là bộ nhớ nhanh, việc đọc không làm hủy nội dung của ô nhớ và …

Volatile memory loses its stored data when the power to the memory chip is turned off. However it can be faster and less expensive than non-volatile memory. This type is used for the main memory in most computers, since data is stored on the hard disk while the computer is off. Major types are: RAM (Random-access memory) – This has become a generic term for any …

The TRS-80 has a full-stroke QWERTY keyboard, the Zilog Z80 processor, 4 KB dynamic random-access memory (DRAM) standard memory, small size and desk area, floating-point Level I BASIC language interpreter in read-only memory (ROM), 64-character per line video monitor, and a starting price of US$600 (equivalent to US$2,700 in 2021). A cassette ...
