Which was the first programmable electronic digital computer, developed in 1943 by Tommy Flowers to break German codes?

A
Colossus
B
Mark I Harvard Mark I
C
ENIAC
D
Z3
Explanation and memory cue

The Colossus, developed in 1943 by Tommy Flowers, was the first programmable electronic digital computer specifically designed to break German codes during World War II. Other options like ENIAC and Z3 were early computers but not used for this purpose or developed at that time.

The Atanasoff-Berry Computer (ABC), developed in 1942 in the U.S., is considered the first ____.

A
Automatic electronic digital computer
B
Programmable electronic digital computer
C
Electromechanical computer
D
Hybrid Computer
Explanation and memory cue

The Atanasoff-Berry Computer (ABC), developed in 1942, is recognized as the first automatic electronic digital computer because it used electronic components to perform digital calculations automatically, unlike earlier electromechanical or mechanical computers.

The Z1 was the first binary mechanical computer, while the Z3, completed in 1941 in Germany by ____, is considered the world’s first working programmable, fully automatic digital computer.

A
Alan Turing
B
Charles Babbage
C
John von Neumann
D
Konrad Zuse
Explanation and memory cue

The Z3, completed in 1941 in Germany, was designed by Konrad Zuse and is recognized as the first working programmable, fully automatic digital computer. The other options are notable figures in computing but not related to the Z3's creation.

Who is considered a pioneer in developing modern computer technology?

A
Bill Gates
B
Steve Jobs
C
Douglas Engelbart
D
Bert
Explanation and memory cue

Douglas Engelbart is widely recognized as a pioneer in modern computer technology. He invented the first practical computer mouse in 1964 and developed the oNLine System (NLS), which introduced many foundational concepts of modern computing such as windows, hypertext, video conferencing, email, and collaborative document editing. His 1968 demonstration, known as the "Mother of All Demos," showcased these innovations and influenced the development of interactive computing and the Internet. While other figures like Alan Turing and John von Neumann are foundational to computing, among the given options, Engelbart is the most accurate choice as a pioneer in modern computer technology. Bill Gates and Steve Jobs are influential in software and personal computing but came later, and "Bert" is not a recognized figure in this context.

The basic operations performed by a computer are?

A
Arithmetic operation
B
Logical operation
C
Storage and retrieval
D
All of these
Explanation and memory cue

A computer performs basic operations including arithmetic operations (like addition and subtraction), logical operations (such as comparisons), and storage operations (storing and retrieving data). Therefore, all the listed operations are fundamental to computer functioning.

Who is known as the father of digital and modern computers?

A
Alan Turing
B
John von Neumann
C
Charles Babbage
D
Blaise Pascal
Explanation and memory cue

John von Neumann is widely regarded as the father of modern digital computers due to his design of the stored-program architecture, which is the foundation of most computers today. Alan Turing made foundational contributions to computing theory but is not typically called the father of modern computers.

Who proposed the stored-program concept?

A
John von Neumann
B
Maurice Wilkes
C
Charles Babbage
D
Howard Aiken
Explanation and memory cue

John von Neumann is credited with proposing the stored-program concept, which is fundamental to modern computer architecture. This concept involves storing program instructions in the computer's memory alongside data, allowing the machine to modify its own instructions.
