What is media in computers? What is the abbreviation of the first electronic computer?

The world's first electronic computer was unveiled in the United States on February 15, 1946, marking the beginning of the computer age. Since the advent of computers, it has brought about earth-shaking changes to us humans. Let's learn what media means in computers and what the English abbreviation of the first electronic computer is, which will help us better explore the past and present of computers.

In computers, media refers to

The media in computers refers to the carriers for representing and transmitting information, which can be divided into five categories, namely sensory media, representation media, performance media, storage media and transmission media. Sensory media refers to media that directly acts on human sensory organs and makes people feel directly, such as sounds that cause hearing.

Presentation media refers to the intermediate media for transmitting sensory media, that is, the encoding used for data exchange, such as text encoding, image encoding, etc.

Presentation media refers to the media used for information input and output, such as input media such as keyboard, mouse, etc., and output media such as monitor, printer, etc.

Storage media refers to the physical media used to store presentation media, such as hard disks, optical disks, USB flash drives, ROMs, and RAMs. Transmission media refers to the physical media used to transmit presentation media, such as cables, optical cables, and communication radio waves.

What is the abbreviation of the first electronic computer?

The English abbreviation of the first electronic computer is ENIAC. The world's first general-purpose computer "ENIAC" was born on February 14, 1946. It was jointly developed by physicist Mauchly and engineer Eckert of the University of Pennsylvania, USA, and is called the Electronic Numerical Integrator and Computer, or ENIAC for short.

The world's first electronic computer "ENIAC" was unveiled in the United States on February 15, 1946. Its advent marked the beginning of the computer age.

The electronic computer "ENIAC" uses 18,000 vacuum tubes, 6,000 switches, 7,000 resistors, 10,000 capacitors, and 500,000 wires.

It covers an area of ​​170 square meters, weighs 30 tons, consumes about 150 kilowatts of power, can perform 5,000 calculations per second, and is used by the US Department of Defense for ballistic calculations.

What are the computer algorithms?

Algorithms can be roughly divided into basic algorithms, data structure algorithms, number theory and algebraic algorithms, computational geometry algorithms, graph theory algorithms, dynamic programming and numerical analysis, encryption algorithms, sorting algorithms, retrieval algorithms, randomized algorithms, parallel algorithms, Hermitian deformation models, and random forest algorithms. Algorithms can be broadly divided into three categories:

1. Finite, deterministic algorithms, which terminate in a finite amount of time. They may take a long time to perform a given task, but will still terminate in a certain amount of time. The results of these algorithms often depend on the input values.

2. Finite, non-deterministic algorithms: These algorithms terminate in a finite amount of time. However, for a given value, the result of the algorithm is not unique or deterministic.
