What is a general model of a computer?
THE GENERAL MODEL OF A COMPUTER All basic computers consist of four functions: input, storage, processing and output. Figure 1.1: The general model of a computer. IPO is often called IPOS or input, process, output, storage.
What are the types of digital computer?
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 digital computer with diagram?
A digital computer is considered to be a calculating device that can perform arithmetic operations at enormous speed. It is defined as a device that operates upon information/data. To be able to process data the computer is made of various functional units to perform its specified task.
What is model and types of model?
A physical model is a concrete representation that is distinguished from the mathematical and logical models, both of which are more abstract representations of the system. The abstract model can be further classified as descriptive (similar to logical) or analytical (similar to mathematical).
What is a standard computer?
A standard is a set of specifications for hardware or software, agreed upon by academic and industry contributors. Common examples of standards include multiple IEEE standards for electrical interfaces (computer cables), ANSI for programming languages, and VESA for computer monitors and video adapters.
What are the three main units of a digital computer?
A traditional digital computer consists of three main units, the processor or central processing unit (CPU), the memory that stores program instructions and data, and the input/output hardware that communicates to other devices.
What is general purpose computer?
A general purpose computer is a computer that is designed to be able to carry out many different tasks. Desktop computers and laptops are examples of general purpose computers.
What was the first digital computer?
ENIAC, in full Electronic Numerical Integrator and Computer, the first programmable general-purpose electronic digital computer, built during World War II by the United States. American physicist John Mauchly, American engineer J.
What is the general model of computer?
Raw facts and figures that can be processed using arithmetic and logical operations to obtain information are called data. The general model of computers can be used to explain how each computer (or smartphone) works. Once you understand how a computer operates, it becomes a lot easier to think about creating your own programs.
What is a digital computer?
The digital computer is a digital system that performs various computational tasks. The word digital implies that the information in the computer is represented by variables that take a limited number of discrete values. These values are processed internally by components that can maintain a limited number of discrete states.
What is a modern computer?
Modern computers are electronic and process digital information. The physical machine consists of transistors, digital circuits implemented with transistors, wires, and mechanical components in peripheral devices used for information storage. These physical entities are collectively called hardware.
How are computers used to model the world?
There are two main methods of modeling the world with a computing machine. Analog computers use some physical phenomenon, such as electrical voltage, to model a different phenomenon, and perform operations by directly modifying the stored data.
