Olympiad Test : Evolution Of Computer - 1 - Class 6 MCQ

The abacus, also called a counting frame, is a calculating tool that was in use in the ancient Near East, Europe, China, and Russia, centuries before the adoption of the written Hindu–Arabic numeral system. The exact origin of the abacus is still unknown.

Invented by Joseph Jacquard and demonstrated in 1801, the Jacquard Loom is an attachment for powered fabric looms. It uses a chain of punch cards to instruct the loom on how to make intricate textiles.

Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining thousands of transistors into a single chip.

Seymour Papert, who was part of the team that first developed Logo, and is often referred to as the "father of Logo".

The IBM 704, introduced by IBM in 1954, is the first mass-produced computer with floating-point arithmetic hardware.

Through their work at Apple in the 1970s and 1980s, he and Apple co-founder Steve Jobs are widely recognized as two prominent pioneers of the personal computer revolution. In 1975, Wozniak started developing the Apple I into the computer that launched Apple when he and Jobs first began marketing it the following year.

Hybrid computers are computers that exhibit features of analog computers and digital computers. The digital component normally serves as the controller and provides logical and numerical operations, while the analog component often serves as a solver of differential equations and other mathematically complex equations.

MOSAIC  is the correct ✔ answer. 
MOSAIC was the first widely- distributed graphical browser or viewer for the World Wide Web. Mosaic arrived in 1993 . Marc Andreessen, then in his early 20 s, is credited with inventing or leading the development of Mosaic.

A second generation of computers, through the late 1950s and 1960s featured circuit boards filled with individual transistors and magnetic core memory. A transistor computer, now often called a second generation computer, is a computer which uses discrete transistors instead of vacuum tubes.

The distinguishing feature of second generation computers (1956-1963) is that they used discrete transistors mounted on printed circuit cards. Examples are the IBM 1401, IBM 7090 and 7094, UNIVAC 1107, PDP-1 and 8. The IBM 7090 was a transistorized version of the vacuum tube IBM 709 machine.

A second generation of computers, through the late 1950s and 1960s featured circuit boards filled with individual transistors and magnetic core memory. These machines remained the mainstream design into the late 1960s, when integrated circuits started appearing and led to the third generation computer.

The first computer systems used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms.

A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.

PDP-11 (Programmed Data Processor-11) is one of the most famous computers in computing history, one of a series manufactured by Digital Equipment Corporation ( DEC ) from the early 1960s through the mid-1990s.
