Mainframe computers are designed for high-throughput, reliable transaction processing and can handle thousands of simultaneous users in large enterprises.
The processing speed of modern supercomputers is universally measured in which of the following units?
FLOPS (Floating-Point Operations Per Second) is the standard metric used to measure the processing performance of supercomputers.
What is the fundamental difference between a Mainframe computer and a Supercomputer?
Mainframe computers excel in processing large volumes of transactions simultaneously (high throughput), whereas supercomputers are optimized for complex, high-speed mathematical calculations.
Which category of computers includes devices like desktop PCs, laptops, tablets, and smartphones?
Microcomputers contain a single microprocessor and include personal devices like PCs, laptops, tablets, and smartphones.
What type of computer is typically configured as a mid-range server to support medium-sized business networks, manufacturing processes, or departmental tasks?
Minicomputers are mid-range systems designed to support multiple users and manage departmental workloads or medium-sized network servers.
Microcomputers are also widely known as "Computers on a Chip" because their entire Central Processing Unit (CPU) is contained on a single chip called a:
A microprocessor is an integrated circuit that contains all the functions of a central processing unit of a microcomputer on a single silicon chip.
In the context of supercomputing, what does the term "Massively Parallel Processing" (MPP) mean?
Massively Parallel Processing involves coordinating many processors to work on different parts of the same program at the same time to achieve ultra-fast computation.
Which of the following is considered the world's first commercially successful minicomputer, launched by Digital Equipment Corporation (DEC) in 1965?
The PDP-8, developed by Digital Equipment Corporation (DEC), is widely recognized as the first commercially successful minicomputer.
Mainframe computers utilize specialized, highly secure, and isolated virtual partitions within a single physical system. These partitions are known as:
Logical Partitions (LPARs) allow a single mainframe to run multiple independent operating system environments securely on the same hardware.
A standard programmable smart watch, washing machine controller, or car braking system uses which specialized type of microcomputer?
Embedded computers are specialized microcomputers designed to perform dedicated control functions within larger mechanical or electrical systems.
Which architectural series introduced by IBM in 1964 is widely credited with establishing the standard design and market dominance of Mainframe computers?
The IBM System/360 was a landmark mainframe architecture that allowed software compatibility across a wide range of system capacities.
Which of the following ranks among the fastest and most advanced supercomputing platforms built by India?
PARAM Siddhi-AI is a high-performance computing-artificial intelligence (HPC-AI) supercomputer established in India under the National Supercomputing Mission.
