A modem (modulator-demodulator) is the device that converts digital signals from a computer into analog signals for transmission over telephone lines and vice versa.

A hybrid computer Resembles both a digital and analogue computer.

Hybrid computers are computers that exhibit features of analog computers and digital computers. The digital component normally serves as the controller and provides logical and numerical operations, while the analog component often serves as a solver of differential equations and other mathematically complex equations.

It contains the parts of an analoge computer and these from a digital computer. Hybrid Computer A hybrid is a combination of digital and analog computers. ... ... Difference between Analog computers digital computers & Hybrid computers Digital Computers operate on inputs and outputs which are in the form of ON-OFF signal.

Digital computer process data which is binary, i.e. in the form of 0 and 1. Analog computers operate on mathematical variables in the form of physical quantities that are continuously varying. For example temperature, pressure, voltages, etc. The basis of the working of the analog computers is modeling.

Digital computers operate by processing discrete data, which involves counting or manipulating binary digits (0s and 1s).

Hybrid computers combine the features of both analog (measuring) and digital (counting) computers to process data.

Digital computers represent data using discrete signals, typically in binary form (on/off states).

Mainframe computers are large, powerful systems designed to handle high-volume data processing and support multiple users simultaneously. Supercomputers are large but focus on computational speed rather than user support.

The vast majority of modern computers are digital, representing data as discrete binary values. Analog computers are largely obsolete, and hybrid computers are relatively rare.

Nanocomputer is the name given to the molecular-scale computer.

Nanocomputing describes computing that uses extremely small, or nanoscale, devices (one nanometer [nm] is one billionth of a meter). In 2001, state-of-the-art electronic devices could be as small as about 100 nm, which is about the same size as a virus. The integrated circuits (IC) industry, however, looks to the future to determine the smallest electronic devices possible within the limits of computing technology.

 Molecular scale electronics, also called single-molecule electronics, is a branch of nanotechnology that uses single molecules, or nanoscale collections of single molecules, as electronic components. Because single molecules constitute the smallest stable structures imaginable, this miniaturization is the ultimate goal for shrinking electrical circuits.

A modern digital computer has Extremely high speed,Large memory and Almost unlimited array.

A supercomputer is a computer with a high level of performance compared to a general-purpose computer. Performance of a supercomputer is measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS). As of 2017, there are supercomputers which can perform up to nearly a hundred quadrillion FLOPS. As of November 2017, all of the world's fastest 500 supercomputers run Linux-based operating systems. Additional research is being conducted in China, the United States, the European Union, Taiwan and Japan to build even faster, more powerful and more technologically superior exascale supercomputers.

Big memory is a term used to describe server workloads which need to run on machines with a large amount of RAM (random-access memory) memory. Some example workloads are databases, in-memory caches, and graph analytics. Or, more generally, data science and big data.Some database systems are designed to run mostly in memory, rarely if ever retrieving data from disk or flash memory.

Sting Ray Torpedo is the first guided weapon in the world which used a programmable digital computer.

The Sting Ray torpedo is a current British acoustic homing light-weight torpedo (LWT) manufactured by GEC-Marconi, who were later bought out by BAE Systems. It entered service in 1983.

A torpedo tube is a cylinder shaped device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels.

Colossus was a set of computers developed by British codebreakers in the years 1943–1945 to help in the cryptanalysis of the Lorenz cipher. Colossus used thermionic valves (vacuum tubes) to perform Boolean and counting operations. Colossus is thus regarded as the world's first programmable, electronic, digital computer, although it was programmed by switches and plugs and not by a stored program.
