Computer Science

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.

An ABC computer is a type of general-purpose computer designed to perform a variety of tasks, not limited to a specific purpose. Therefore, the correct answer is 'General-purpose computer'.

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 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.

The Harvard Mark I, developed by Howard Aiken in 1944 for the U.S. Navy, was an electromechanical computer. ENIAC and Colossus were electronic computers developed later, and the Atanasoff-Berry Computer was an earlier electronic prototype not developed by Aiken.

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 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.

Ada Lovelace is credited with writing the first algorithm intended for implementation on Charles Babbage's Analytical Engine, making her the first to introduce computer software concepts in 1843.

ENIAC (Electronic Numerical Integrator and Computer) was the first electronic general-purpose computer, completed in 1945. UNIVAC, EDSAC, and MARK-I were subsequent early computers but came after ENIAC.

Charles Babbage is known as the Father of Computers because he conceptualized and designed the first mechanical computer, the Analytical Engine, which laid the foundation for modern computing.

ENIAC stands for Electronic Numerical Integrator and Computer, which was one of the earliest general-purpose electronic digital computers.

Alan Turing developed the concept of the Universal Turing Machine, which is foundational to modern computer science and the design of the first computers.

The primary function of a computer is to collect, store, and process data to produce meaningful information. Options A, C, and D are unrelated to the fundamental purpose of computers.

Fuzzy logic is a concept used in computer science and related fields to handle reasoning that is approximate rather than fixed and exact. It is not related to Aristotle’s philosophy, Epicurianism, or Sophism.

ASCII is an acronym for American Standard Code for Information Interchange. It is a 7-bit character encoding standard that represents text in computers, communications equipment, and other devices. This code is foundational for data representation in computing.

BUS is a type of network topology where all devices share a single communication line. LAN, WAN, and MAN are types of networks classified by their geographical coverage, not topologies. Other examples of topologies include Star, Ring, and Mesh.

Avira, Kaspersky, and McAfee are well-known antivirus software used to protect computers from malware and viruses. Oracle is a software company mainly known for database systems, not antivirus software, so it is the correct answer.

Android version names are dessert-themed nicknames such as Cupcake, Gingerbread, and Honeycomb. However, 'Muffin' was never an official Android version name, making it the correct answer.

A PDA (Personal Digital Assistant) is a handheld device that runs a mobile or embedded operating system designed for portable use. Supercomputers, personal computers, and laptops use full desktop or server operating systems rather than handheld operating systems.

Computers classified by size include microcomputers, minicomputers, and mainframe computers. 'Digital computer' is a general category based on data processing type, not size classification, so it is the correct answer.

Cache memory is a small, high-speed memory located close to the CPU that stores frequently used data and instructions. It reduces the time needed for the CPU to access data from the main memory, thereby improving overall processing speed. RAM, ROM, and EPROM do not function as high-speed intermediary storage between CPU and memory.

PROM (Programmable Read-Only Memory) is a type of non-volatile memory, meaning it retains data even when the power is turned off. RAM, DRAM, and registers are volatile memories that lose their data when power is removed.

A light pen is an input device used to select or draw directly on a computer screen. VDU (Visual Display Unit), TV, and printer are output devices, so they are not used for input.

FORTRAN (Formula Translation) is one of the earliest high-level programming languages and was developed for scientific and mathematical computations. It is problem-oriented and widely used in engineering and scientific fields. However, requiring extensive internal documentation is not a defining or mandatory characteristic of FORTRAN.

DHCP (Dynamic Host Configuration Protocol) is the protocol used to automatically assign TCP/IP configuration information such as IP address, subnet mask, default gateway, and DNS servers to devices on a network.
