Answer: Option B. -> Embedded computers
Answer: (b)
Embedded computers are specially designed computer chips that reside inside other devices, such as your car or your electronic thermostat.
An embedded system is a programmed controlling and operating system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts.
Embedded systems tutorial includes. Embedded systems are a cornerstone of the electronics industry today. An embedded system is a computer or processor-based system that has been designed for a specific purpose.

Answer: Option A. -> System Software
Answer: (a)
Operating system, editors, and debuggers comes under System Software.
System software is computer software designed to provide a platform for other software. Examples of system software include operating systems like macOS and Windows, computational science software, game engines, industrial automation, and software as a service application.
A debugger or debugging tool is a computer program that is used to test and debug other programs (the "target" program). ... For example, the program might have tried to use an instruction not available on the current version of the CPU or attempted to access unavailable or protected memory

Answer: Option B. -> processing
Answer: (b)
Data processing is a procedure that is usually carried out by a computer. The manipulation of data by a computer is known as data processing.
Data processing encompasses the use of computers to execute prescribed operations on data. Information is retrieved, transformed, or classified as part of the process.
The translation of input data into a more comprehensible form is known as processing. The production of the required information, which may be input in the future, is referred to as output.

Answer: Option A. -> EDSAC
Answer: (a)
EDSAC is The first computer used to store a program.
It was subsequently developed into the Manchester Mark 1, which ran its first program in early April 1949. Electronic Delay Storage Automatic Calculator, EDSAC, became fully operational providing a service to a range of customers on May 6, 1949.
The Manchester Baby, also known as the Small-Scale Experimental Machine (SSEM), was the world's first stored-program computer. It was built at the Victoria University of Manchester, England, by Frederic C. Williams, Tom Kilburn and Geoff Tootill, and ran its first program on 21 June 1948.
