Where did computers came from?
You can't really put the credit on just one or two people. One guy discovered electricity (B. Franklin) then another guy used this electricity to make the first micro chip. Then another guy made another part that can be found in a PC, till voila! You got one great invention that was pieced together over thousands of years by thousands of different guys!
Try making your question more specific, like: "Who (what company or what group of nerds :P ) was responsible for making the version [put version name here] of the PC?" OR "Who made [put name of computer part here] and when did they make it?"

Or if you want to just get right to the point, Ed Roberts of MITS (Micro Instrumentation and Telemetry Systems--the company was founded to make telemetry equipment for model rockets, and its first successful product was a calculator) is considered the father of the personal computer. He designed the Altair 8800, which sold in kit form for about $400.
Now understand that a "computer kit" in the 1970s was far different from one today. If you were to "build your own computer" right now, you'd buy a big pile of prebuilt parts, put a premade operating system and premade programs on it, and be playing Doom within two or three hours. In the 1970s you got a printed circuit board with nothing soldered to it, and big bags of resistors, capacitors, integrated circuits and so on. And you better know how to read a resistor color code because that's the only labeling you were going to get. Added bonus: it LOOKED like a computer, which computers don't anymore.

The first general purpose computer was the Electronic Numerical Integrator and Computer (ENIAC) it was unveiled February 14, 1946 and created by John Adam Presper Eckert Jr and John Mauchly for the purpose of calculating artillery firing tables. It was also able to be reprogrammed to solve a full range of computing problems.
DECADES LATER, Henry Edward "Ed" Roberts invented the first commercially successful personal computer in 1975.

How does the computer that Konrad Zuse invented work?
Konrad Zuse invented a number of different calculating machines, most of them being named by a Z followed by a number. His first machine, the Z1, was entirely mechanical. Starting with the Z2, relays were used, though the memory stayed mechanical. The Z3 used relay based memory, though the Z4 reverted back to mechanical. The mechanical memory had an advantage in size. The Z4's memory took less than one cubic meter to hold an amount of data that would have required a relay based memory occupying a large room to hold. Later computers were vacuum tube based (the Z22) and eventually moved to transistors. However, when Zuse was first working on his machines, vacuum tubes were not available in the quantities he needed in WWII Germany.
How do you delete your history on the computer?

What is India's first super computer?
India's First Supercomputer was PARAM 8000. PARAM stood for Parallel Machine. The computer was developed by the government run Center for Development of Advanced Computing (C-DAC) in 1991. The PARAM 8000 was introduced in 1991 with a rating of 1 Gigaflop (billion floating point operations per second).
All the chips and other elements that were used in making of PARAM were bought from the open domestic market. The various components developed and used in the PARAM series were Sun UltraSPARC II, later IBM POWER 4 processors, Ethernet, and the AIX Operating System. The major applications of PARAM Supercomputer are in long-range weather forecasting, remote sensing, drug design and molecular modelling
You can put mousse in your hair rub your finger in your scalp to get all the mousse in it and after that you can put your hair in a messy bun and sleep on it or here is another way to get wavy hair. Twist your hair in sections after a shower and leave it in for 2 hours or sleep on it and when you take it untwist it a bit. For better results sleep on it.
Hope,
this helped!
Who created the first computer programming language?
The first programming language was Lambda Calculus Here is the link to the website
[URL]http://en.wikipedia.org/wiki/Lambda_calculus#Lambda_calculus_and_programming_languages[/URL] It was introduced by Alonzo Church and Stephen Cole Lleene in the 1930s
There are many components in a computer. In order to understand how a computer works, one must know the basic components. Open the case and look at all the gizmos. There are 4 basic parts to a computer (PC): CPU- Central Processing Unit GPU- Graphics Processing Unit PSU- Power Supply Unit Memory- Temporarily stores data from the hard disks Without these components, the computer will not function normally.
There are other devices that can be attached to the PC. CDROMs, Hard Disks, Floppy Disks, Sound Cards, TV tuner cards, mice, keyboards, NICs (network interface card), and USB cards. The devices are not needed to make the PC run.
Let's trace a packet of data from power on to it's final destination, the monitor. First, the packet is stored on the hard disk. It goes from the hard disk through the ribbon cable, which connects the hard disk to the motherboard, then to the memory. From the memory, it travels through the FSB (Front Side Bus) to the cache on the CPU. There, it waits until it is needed by the CPU. When it's needed, it goes to the GPU which in turn generates an image that goes to the monitor. Seem like a lot? Computers are not simple, ever.
This is an old video, but it is pretty good:

When was the computer developed?
The first computer that could store a program (software) was the Manchester Small Scale Experimental Machine, nicknamed the Baby. This was in 1948 at the University of Manchester in England. Tom Kilburn wrote the first program to be executed on the Baby. So it could be argued that:
Tom Kilburn invented the software.
What are information technology resources?
There are several good IT resources available online. The best one I can think of is Google. I can't tell you how many times that I need to search for some obscure issue on google and find exactly what I am looking for. Another good resource is Experts Exchange (www.experts-exchange.com). They have an impressive amount of information on a wide range of IT related subjects. Also, this site is good for that! There are lots of answered questions here that are useful in the field of Information Technology.
What were 1970's computers used for?
In the 1970s, computers were used in banking and for the (then quite new) credit card systems. They were also used in universities and large national organisations requiring computing power - such as the Meteorological Office in the UK (for weather forecasting) and NASA in the USA. Most offices did not have one and virtualy no one used one at home.
There were a limited number of personal computers, much larger than today's standalone computers (and very much large than laptops!). These just used a keyboard for input and a screen (VDU) that only displayed lines of text. These would have been used on some offices - with no Internet or other connectivity and very limited (black and white) printing.
What did the computers look like in the 1960's?
Computers in the 1960s were huge, heavy machines that took up entire rooms in air-conditioned buildings. (Think of rows and rows of refrigerators filling up a hall)
Expanded AnswerIn the sixties, computers were huge, but more huge (huger?) than the previous answer allows. Catch "A Touch Of Mink" on TMC or AMC some time. (Stars Doris Day and Cary Grant; MARVELOUS!) You'll see a fair representation of a "computerized" business of the day. Keep in mind that the machines that Doris Day sabotages, the ones that malfunction, are merely terminals; they're just card readers, and the actual computers are in many more cabinets spread all over the building. Additional ExpansionLarge computers looked like rooms full of lockers, som had glass/acrylic doors behind which you could see tape drives (reels of magnetic tape that rotated jerkily to get to the data on the tape).There were very few small computers but one was the Olivetti Programma 101 (google that to find pictures of it) a desktop computer that looked like a cross between a calculator and a typewriter.
Super old and not worth looking at. If you have ever seen Terminator 3, at the end it shows some pretty old computers, if you look at those then you get the idea.
The main advantage of a GUI is that the visual representation of functions allows easier use of the computer compared to a command-line-based interface. It also speeds up the user's work for non-technical people.
Which three parts of the computer give output?
The desk, the keyboard, and anything that lets the aputer run.(screen, power cord like and Xbox power cord.
What is the purpose of the at command atmo?
At is a command used in computing that can be used in Microsoft Windows ReactOS, and Unix-like operating systems to schedule commands to run once at a specific time in the future. Call Now :- 8851166837
What is the Key Text for Confucianism?
'''The Confucian Classics''' (five books) and '''The four books''' (four books)
Does computer have a negative influence on people?
I would say that PC's do definitely have a negative effect on people, Not only do they provide A very enticing cover for crooks, but they also luer people who would not normally be crooks to do things they would normally not have the courage to do.
How does e-waste affect the atmosphere?
e waste affects the atmosphere because it cause polution into the air and kills animals people and the environment
What kind of jobs can you get with an Associates Degree in Computer Information Systems?
The best place for the answer to this question is the college offering the degree. The division office or academic department that offers the degree should have information on the kinds of jobs their graduates have obtained.
There are more than three types of input device...
* Mouse * Keyboard * Microphone * Touchscreen * Scanner * Joystick * Barcode reader ... are just a few
How are computers used by the Army?
Computers technologies are used by the military on a daily basis. The computer technologies that are used include signals intelligence, radio intelligence, and computer networks used by military intelligence soldiers.
Who were caliphs and how did they administer their empire?
Caliphs were successors of Muhammad as spiritual and temporary leader of the Muslims. They administered the empire by keeping everyone in line.
Meaning of each Ten Commandments of Computer Ethics?
Ten Commandments of Computer Ethics Computer ethics relates to the ethical values that should guide the computer professionals in their conduct. The Ten Commandments of Computer Ethics establish guiding principles for all of us to follow. Read on to know these Ten Commandments.
Every sphere of life is guided by a set of rules of what is right and what is wrong. The difference between the 'right' and the 'wrong' has to be demarcated in any walk of life. With the development of technology and the increase in its use, society had to confront ethical issues relating to the harnessing of technology. Every science of life needs to base itself on ethics and so does computer technology! The Computer Ethics Institute came up with The Ten Commandments of Computer Ethics, in 1992. The intent behind the creation of these Ten Commandments was to establish a set of standards to instruct people to use computers ethically.
Thou shalt not use a computer to harm other people.
This commandment makes clear that it is unethical to use a computer to harm another user. It includes harming or corrupting some other user's data or files. The commandment states that it is wrong to steal someone's personal information by means of a computer. It is unethical to manipulate or destroy the files of other people through the use of a computer. It iterates the fact that writing a programs intended to bring perform ethically wrong actions, is in itself unethical.
Thou shalt not interfere with other people's computer work.
Viruses are small programs built with intent to harm or disrupt the useful computer programs. Some viruses aim at overloading the computer memory by an excessive use of computer resources. These viruses tend to fail a computer in executing the desired tasks. They lead to the dysfunction of a computer. The development or the spread of such malicious software in unethical.
Thou shalt not snoop around in other people's files.
We know that it is wrong to read another person's letters. On similar lines, it is unethical to read another person's email messages. Obtaining another person's private files is as wrong as breaking into someone's room. Snooping around in another person's files or reading someone else's personal messages is the invasion of his/her privacy. In order to protect the information from being attacked, it is ethical to apply encryption schemes to it.
Thou shalt not use a computer to steal.
The stealing of sensitive information such as the personal information of the employees from an employee database, or breaking into bank accounts for the retrieval of confidential information is nothing less than robbery. An illegal electronic transfer of funds is one type of a fraud.
Thou shalt not use a computer to bear false witness.
Computers are the easiest sources of spreading information to the masses by means of Internet. This also means that false news or rumors can spread speedily and easily through the Internet. Being involved in the circulation of incorrect information is unethical. Spreading the wrong information by means of Internet is like taking an undue advantage of technology.
Thou shalt not use or copy software for which you have not paid.
Like any other artists or literary work, software is also subject to copyrights. Software is the outcome of a programmer's intellect and it is important to respect talent and give due regard to his/her rights. Obtaining illegal copies of copyrighted software is unethical.
Thou shalt not use other people's computer resources without authorization.
Multi-user systems are supported by user specific ids and passwords. Breaking into some other user's password, thus indulging into his private space on the network is unethical. It is not ethical to hack passwords for gaining an unauthorized access to a password-protected computer system.
Thou shalt not appropriate other people's intellectual output.
Programs developed by a programmer in an organization are his/her property. Copying them and propagating them in one's own name is unethical. A creative work, a program or a design that a particular employee comes up with, is his/her ownership. It is the output of someone's intellect and efforts. Copying it with selfish intentions is indeed not ethical.
Thou shalt think about the social consequences of the program you write.
Looking at the social consequences that a program can have, describes a broader perspective of looking at technology. A computer program goes a long way to reach homes of the masses. In case a person is working for animation films or he/she is designing a video game, it is the programmers responsibility to pay heed to the effects of his/her creation. In case of software, it is important for the programmer to realize the prospective use of the software. Writing a virus, when one knows that it is going to serve as a malware, is indeed unethical. If a particular content is intended for children or when children are prone to gain access to the content, it is necessary for the creator of such content to be careful about the social consequences it is bound to have.
Thou shalt use a computer in ways that show consideration and respect.
In the real world, we face situation wherein we need to be courteous to our fellow mates. Many times, we need to cooperate with them and give each of the fellow individuals the consideration due. On similar lines, while interacting through a computer, a person needs to be nice to the ones he/she interacts with.
The Ten Commandments of Computer Ethics are the means to build a set of regulations to guide the individual users to base computer related operations on strong ethical values. The commandments are a way to make people understand the ethics involved in the use of technology.
