Software is a general term for the various kinds of programs used to operate computers and related devices. There are two types of software system and application. :)
Yes, the word 'software' is a common noun, a general word for any of the various kinds of programs used to operate computers and related devices.
Yes, that is correct. The "programs" or "software" are actually instructions, for the computer to carry out different tasks in a specified way.
yes, if they're mechanical devices.
Bluetooth devices allow one to be hands free and operate devices at the same time. This is commonly used on cell phones, computers, and modern tablets.
Some electrical devices that protect our environment include solar panels and computers. Solar panels collect power from the sun while computers help calculate efficient ways to operate equipment.
All modern day computers are built using electronic or semiconductor processors and components, so these are electronic systems which of course need electrical power to operate but are not in general put under category of electrical devices.
Software is the programs that are used by a computer. The computer user is able to use a variety of software to operate the computer or other devices that use software.
Computers are only as smart as the person using them. Computers are only as smart as the person using them. Computers are not smart. They are dumb pieces of machinery that run on programs written by smart people. If the program isn't correct, the computer cannot operate.
The first computers used punch cards to operate and get them to do calculations. Then they came out with computers that had keyboards and you used 8" floppy drives where everything you did was either programming or off of programs contained on those disks. Now you have operating systems and can save and run programs off your hard drive. You don't need to know ANY programming to run today's computers.
A dual band router will allow 802.11g devices to operate on the 2.4 GHz band while allowing 802.11n devices to operate at their maximum speed on the 5GHz band. Both the G and N devices will be able to operate simultaneously.
Computers aren't discovered; they are DESIGNED to do what they do. Engineers and programmers worked to develope computers since the 1940's so they could compute and then designed them to print and draw and operate machinery, etc. The question is too general to give a precise answer.
