Analogue
digital computers were first used in 1942 analog computers were first used in about 100BC
Analog computers were first made in the late 1920s, Digital computers were first made in the early 1940s.
the first electronic digital computer was made in Ames, IA in 1942. the first analog computer known was made in one of the colony city states of greece in about 100BC.
Digital images are transmitted on computer networks by first compressing them to reduce their size. JPEGs are an example of compressed image files.
The first Indian analog computer was assembled in 1950
No, Pulse Code Modulation is a communication method used to carry digital data but is not part of any analog to digital conversion. PCM is often used to carry audio data as a digital stream and therefore is the encoding used as the signal is first converted to a digital format.
First there was analog. Then Digital came along and said 'Get you hands outta my face!' Digital then was born.
Analog television was first used in the 1930s. Analog signals are sent by varying voltage, radio frequencies, and static images.
The first digital computer was called ENIAC
The majority of modern computing devices are digital. That means they work by using many on and off type electrical signals. Analog computers work by using vary ranges of constantly-changing signals in real-time without converting them to digital sequences first.
No, the following digital computers preceded ENIAC: Harvard Mark I, ABC, Zuse Z1 & Z2 & Z3, Colossus Mark 1 & Mark 2. Also many analog computers preceded these.However ENIAC was the first general purpose programmable electronic digital computer.
The credit for the first programmable digital computer goes to Colossus which was an Allied WWII code-breaking machine at Bletchley Park. For other uses of the term computer besides the modern "digital computer" one, an earlier answer might apply.
