Computer Fundamentals and System Concepts

The second generation of computers (roughly 1955-1965) replaced vacuum tubes with transistors, which were smaller, faster, and more reliable.

The MANIAC (Mathematical Analyzer, Numerical Integrator, and Computer) was built at Los Alamos and was used for calculations related to the hydrogen bomb project.

Charles Babbage's Difference Engine was a mechanical calculator designed to be powered by steam, intended to automate the calculation of mathematical tables.

The EDVAC (Electronic Discrete Variable Automatic Computer) was one of the earliest computers to implement the stored-program concept, following the theoretical design of Von Neumann.

The PowerPC architecture, developed by the AIM alliance (Apple, IBM, Motorola), is a classic example of RISC (Reduced Instruction Set Computer) technology.

A hub is a physical networking device used to connect multiple devices in a network, making it hardware.

A network bridge is a computer networking device that creates a single, aggregate network from multiple communication networks or network segments.

A prototype is an early, simplified version of a proposed system used to test concepts and gather user feedback before full-scale development.

An MIS is primarily about information flow and decision support; while computers are common tools, the foundation must be proper organizational systems and procedures.

Artificial Intelligence (AI) is the field of computer science dedicated to creating systems capable of performing tasks that typically require human intelligence, such as reasoning, learning, and problem-solving.

An integrated circuit (IC) is a set of electronic circuits on one small flat piece (chip) of semiconductor material, usually silicon, which functions as a single unit.

An operating system (OS) is the system software that manages computer hardware, software resources, and provides common services for computer programs.

A modem (modulator-demodulator) is a hardware device that converts data between digital signals used by computers and analog signals used by telephone lines.

A computer executes instructions contained within a program. While programs are built using algorithms, the computer itself executes the compiled or interpreted program code.
