Which of the following is generally costlier?
Mainframes are large-scale enterprise systems costing millions of dollars, vastly exceeding the cost of individual servers or personal computers.
The user generally applies _________ to access a mainframe or supercomputer.
Users historically connected to mainframes via individual nodes, workstations, or dumb terminal stations.
Pratyush is the _________ fastest supercomputer in the world.
India's high-performance supercomputer, Pratyush, achieved high global and local rankings, including being fourth in specific meteorological clusters.
Pratyush supercomputer is dedicated for:
Built at the Indian Institute of Tropical Meteorology (IITM), Pratyush is primarily dedicated to advanced weather and climate forecasting.
Time sharing became possible in _________ generation of computers.
Early forms of time-sharing research and architectures began emerging during the second generation of computers.
Integrated Chips or ICs were started to be used from which generation of computers?
The third generation of computers transitioned to integrated circuit (IC) chips, replacing discrete transistors.
Chip is a common nickname for a(n):
Integrated circuits are colloquially referred to as microchips or silicon chips.
First computer of India is:
Siddhartha was the first indigenous computer manufactured in India, installed in Bangalore main post office in 1986.
Who developed integrated chip?
Jack St. Clair Kilby of Texas Instruments (along with Robert Noyce) co-invented the first integrated circuit in 1958.
In latest generation computers, the instructions are executed:
Modern CPU architectures execute instructions both sequentially and in parallel through pipelining and multi-core processing.
Microcomputer hardware consists of three basic categories of physical equipment:
The three core physical components of a microcomputer are the system unit, the memory subsystem, and I/O devices.
Which of the following options correctly expresses the meaning of the term 'PCs'?
Personal Computers (PCs) are designed to provide individual users with standalone storage and processing capabilities to maximize personal productivity.
The Napier’s technology used for calculation is called:
John Napier described his calculating rods system and mathematical calculations in a book called Rabdologia, published in 1617.
Pascaline is also known as:
Blaise Pascal's mechanical calculator, the Pascaline, was designed principally to function as a reliable adding machine.
Punched cards were first introduced by:
Joseph Marie Jacquard invented the concept of punched cards to automate textile patterns on his famous weaving loom.
Analytical Engine developed by:
Charles Babbage designed the mechanical Analytical Engine, establishing the architectural basis for general-purpose computers.
The Analytical Engine developed during first generation of computers used _________ as a memory unit.
The Analytical Engine was designed to use physical, mechanical counter wheels to store numerical values and programmatic state variables.
Tabulating machine was the first electromechanical machine developed by:
Herman Hollerith designed the first electromechanical tabulating machine to process and record data for the 1890 US Census.
The first computer which provides storage is:
EDSAC (Electronic Delay Storage Automatic Calculator) was the first practical stored-program computer to offer internal data storage using mercury delay lines.
Computer built before the first generation computer was:
Pre-first-generation computers (such as Harvard Mark I) relied on electromechanical relays rather than purely electronic vacuum tubes.
Collecting the data and converting it into information is called:
Processing is the system act of manipulating, formatting, and structuring raw inputs (data) into useful outputs (information).
Part number, description and number of parts ordered are examples of:
Data parameters describing inventories and orders represent intermediate data elements subjected to system processing.
Benefits of computers are:
Computers offer high-speed arithmetic execution and immense storage capacity, though they still rely on correct inputs (GIGO) and cannot think independently.
