What is digital word in computer?
Digital describes electronic technology that generates, stores, and processes data in terms of two states: positive and non-positive. Positive is expressed or represented by the number 1 and non-positive by the number 0. Thus, data transmitted or stored with digital technology is expressed as a string of 0’s and 1’s.
What is digital computer example?
In computer science, a digital electronic computer is a computer machine which is both an electronic computer and a digital computer. Examples of a digital electronic computers include the IBM PC, the Apple Macintosh as well as modern smartphones.
Who discovered digital computer?
The English inventor Charles Babbage, however, is generally credited with having conceived the first automatic digital computer. During the 1830s Babbage devised his so-called Analytical Engine, a mechanical device designed to combine basic arithmetic operations with decisions based on its own computations.
What is computer definition and its types?
A computer is a machine that can be programmed to manipulate symbols. Its principal characteristics are: It responds to a specific set of instructions in a well-defined manner. It can execute a prerecorded list of instructions (a program). It can quickly store and retrieve large amounts of data.
What is digital computer and its type?
It uses electronic technology to generate, process, and store the different types of data. Based on the types and size of the device, these digital computers are divided into 4 types namely Micro computer, Mini computer, Mainframe computer, and Super computer.
What is the name of first digital computer?

What does digital computer mean?
digital computer, any of a class of devices capable of solving problems by processing information in discrete form. It operates on data, including magnitudes, letters, and symbols, that are expressed in binary code —i.e., using only the two digits 0 and 1.

What are digital computers with examples?
These methods include an interrelated set of skills, such as pattern recognition, abstraction and decomposition, applied to solve complex problems using, for example, automation, data analysis or computational modeling. These skills and practices can be used to learn topics in many disciplines.
