System software is a type of computer program that is designed to run a computer’s hardware and application programs.
Generalized software refers to software designed to read, process and write data with the help of functions performing specific audit routines and with self-made macros.
A power supply unit (or PSU) converts mains AC to low-voltage regulated DCpower for the internal components of acomputer. ... Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage.
Answer: A. Multicast
Explanation:
Here we are given a situation where it is necessary for the device to stream media to all the PCs connected across the LAN. But as the they are unable to stream the media then it is a problem in the multicast TCP/Ip technology.
Multicasting enables to transfer information or messages from one to many or many to many. Here as a single device is responsible for streaming the content to other PCs across the LAN, therefore it is necessary that multicast has been properly implemented.
Option B is incorrect as it is not a scenario of broadcast as in broadcasting all the receivers must get the streaming however here if a PC does not want to receive the media stream it cannot receive for which multicasting is required.
Option C is incorrect as here we are not talking of one to one communication.
Option D is incorrect as here we cannot have more than one route to send the media content except the LAN.
Answer:
Grace Hopper.
Explanation:
Grace Hopper was a US Naval Rear Admiral and an American computer scientist who was born on the 9th of December, 1906 in New York city, United States of America. She worked on the first commercial computer known as universal automatic computer (UNIVAC), after the second World War II.
In 1953 at the Remington Rand, Grace Hopper invented the first high-level programming language for UNIVAC 1 by using words and expressions.
Hence, Grace Hopper was the Navy Admiral who invented a high-level programming language FLOW-MATIC in 1953.
Additionally, FLOW-MATIC paved the way for the development of common business-oriented language (COBOL).
