Answer:
c. StringBuilder
Explanation:
An alternative to the String class would be the StringBuilder Class. This class uses Strings as objects and allows you to mix and match different strings as well as adding, removing, implementing, and modifying strings themselves as though they were similar to an array. Unlike the string class StringBuilder allows you to modify and work with a combination of strings in the same piece of data as opposed to having various objects and copying pieces which would take up more memory.
Answer:
Internal:
#CPU; That retrieves &execute instructions.
#Modem; Modulates& demodulates electric signals.
#RAM;Gives application a place to store &access data on a short time periods.
External:
#Mouse; Transmits commands and controlling movements.
#Moniter; Device used to display video output from computer.
#Printer; Accepts text, graphics to the paper.
Explanation:
Hope this will help you.
Answer:
What is Robotics?
Robotics is the branch of technology that deal with the design, construction, operation and application of robots as well as computer system for there control, sensory feed back, and information processing. the design of given robotic system often contain principle of mechanical or electronic engineering and computer science. The word robotic was first used in 1941 by the writer Isaac Asimov.
Branches of robotics:
Artificial intelligence: The developing of an intelligence of machine and is a branch of computer science.
Nano Robotics : the field of creating machines that are at a scale of a nano meter.
Tele-presence: The study given to an illusion of being at a place without being there physically.
Robot Locomotion: The study of method that Robots used to transport them selves from place to another.
Robots have long captured the human imagination but despite many advances robots have yet to reach the potential so often envisioned in science fiction today engineers and computer scientist are still pursuing one missing ingredient high intelligence it would be nice for example: if robots possessed the intelligent needed to cope with uncertainty, learn from experience and work as team.
Intelligent robots will be one of the engineering achievement of 21 century said Junku Yuh, how leads the robotics program in the national science foundation computers and information science and engineering directorate "we will see them more and more in our daily life".
