The main 'challenge' is security ! Experts are in a constant battle to keep peoples personal information secure, and only accessible by those authorised to see it. Hackers think it's funny to break into a persons computer - they don't realise (or don't care) how violated it makes someone feel to find out their personal information is now broadcast all over the internet. Stealing someone's 'identity' Is worse than being burgled (and I speak from experience) !
Challenges that computers bring to society would be:
- People get replaced by computers.
- tree's get sved, because people typ instead of write.
- Find definations easily, instead of searching through a dictionary
- Identity thefts
- hackers
- lose information easily. If your compurter crashes or malfunctions
- medical
- easy to demonstrate things to a school or class
If you mean sortof like a digital society of real people, then a challenge is definitely portraying emotion. I hope this helped you.
All computers are digital. *Analogue
There have been mechanical computers in the past, but they were rare. Today the odds are good that any computer you encounter is digital.
personal computer, hand held computers,work station, Mid range station, main frame, and supercomputer
A hybrid computer is a type of computer that is no longer made. It contains two interconnected computers: a digital computer and an analog computer. In most hybrid computers, part of the analog computer's program is entered manually by plugwires on plugboards and part by the digital computer switching relays and setting digitally controlled pots. The digital computer program was entered from tape or disk.Most of them were custom built systems generally used for control system simulation modeling. The analog computer was programmed to model an open loop real world system and the digital computer was programmed to control it and thereby close the loop. Some systems tested this way were:Nuclear Reactor control systemsAircraft flight control systemsChemical reaction control systemsIndustrial process control systemsetc.Another use of hybrid computers was high speed drawing of "stroke graphics" (dots, vectors, arcs) on random deflection high brightness CRT displays (another long gone technology).The last hybrid computers I saw operating were in about 1986. Haven't heard of any made since then.
The difference between an analog and digitialcomputer is the type of data they process. Analog computers process measured data. A speedometer in your car is a common type of analog device. A digital computer processed descrete data (digits). In this case 0 and 1. Digital computers are most common. PC's, MAC's are digital computers. A big difference is an analog computer's output can vary even if the input is identical. A digital computer can be very precise. For instance, a gas pump might tell you that you pumped in 5 gallons of gas but you could have gotten 4.99 gallons or 5.01 gallons. If you asked a digital computer to add 5 and 6 together, you will always get 11. By the way. A gas pump is actually a hybrid computer. Although it processes measured data, that is how much fluid has passed through the gas hose, the data displayed to you, the amount of gas and how much you owe is in a digital format.
Included in this industry are digital computers, analog computers, and hybrid digital/analog computers.
Digital computers work with exact discretely coded representations of numbers.Analog computers work with approximate continuous representations of numbers.Hybrid computers are computers that are part digital part analog.I have used all three types, each has advantages.
built with the same level of technology, analog computers are always faster but less accurate than digital computers. however as little significant work on analog computers has been done since the 1980s, they currently significantly lag behind digital computers in speed.
No, a laptop is a kind of digital computer. Analogue computers used operational amplifiers in feedback loops to simulate dynamic systems such as aircraft. They began to be replaced by digital computers in the 1960s
No, your desktop computer is a digital computer as are virtually all modern computers.
All computers are digital. *Analogue
Digital computers are classified based on their size into microcomputers, minicomputers and mainframe computers. Other types include supercomputers, network computers, laptops, palmtops and PDAs.
There is a great scope in computer engineering. In Computer engineering, students study the design of digital hardware and software systems including communications systems, computers and devices that uses computers.
a. computers are used in all digital technologies.
Computers are designed according to the data they are supposed to process. In this regard there are three types of computers Analogue, Digital and Hybrid.
digital computers were first used in 1942 analog computers were first used in about 100BC
Analog computers were first made in the late 1920s, Digital computers were first made in the early 1940s.
