Why is computer called personal computer?
Not all computers are called personal computers.
A personal computer (PC) is any general-purpose computer whose size, capabilities, and original sales price make it useful for individuals, and which is intended to be operated directly by an end user, with no intervening computer operator.
It is called a personal computer because, it uses a micro-chip.
So that people can go on wikianswers and find out why computers are made today
Why computer is important in the modren world?
Computer is important now-a-days, because it saves labors.......We also can say that computer as a labour saving machine. At ancient time there was need of 5 peoples to work on a data but now-a-days just by 1 person it is possible, through a computer, thourgh a database.
What is the difference between mini and micro computer?
These days? Very little; in the old days a 'mini' was something that fit into 1 room; a mainframe typically occupied several rooms and a PC (micro) was a desktop...
Nowadays, my calculator is a micro if you want to use the truest sense of the word. Today's calculators are more powerful than the worlds first Mainframe computers.
In what ways can a computer process data?
The part of the computer that processes data is called the processor or processing unit. Older computers had a Central Processing Unit (CPU) . Modern machines often have more than one processing unit. The processor fetches and decodes the instructions that make up the program as well as doing the arithmetical operations.
Pictures of different types of computers?

What are the four basic functions to a computer?
- Arithmetic Logic Unit - perform calculations and logic functions
- Memory Unit - store data and instructions
- Control Unit - fetch instructions, decode instructions, and control the other units as requested by the instructions
- Input/Output Unit(s) - move data and instructions into and out of the computer
What helped to create the computer?
What made modern computers possible was the invention of something that could do calculations and other information processing with no moving parts and do it very fast. That something was electronic components. With electronic components, a fast and efficient machine such as Babbage proposed could be built with all four components essential to modern computing.

The Nez Perce Indians, would live mostly on a diet of salmon, roots, and berries.
The Nez Perce Indians lived mostly on Salmon, root's and bulbs, berries, nuts, deer, bear, and buffalo.
What are the impacts of computers on environment?
I belive some computers add to the incessant increase of pollution in terms of garbage and such. However, it also has positive effects such as the innovation it brings in protecting and preserving the environment.
Who made the first man made computer?
Which device is considered the first computer is somewhat debatable. Some consider the abacus to be the first computer. The first programmable machine was invented by Al-Jazari, but it didn't perform calculations. (It was a humanoid robot that played music.)
The first general use computer was designed by Charles Babbage, but was never entirely built, and would have been entirely mechanical. (He couldn't get the funding. Whether it would have worked with the technology available at the time is debated.) If it had been built and worked, it would have been the first Turing-complete computer (except that a truly Turing-complete computer would need infinite memory). To be Turing-complete means to be able to simulate any other computer. (It doesn't have to simulate it in real time.) In other words, it can (in theory) be programmed for any (computational) task.
The Z3 was designed by Konrad Zuse. It was the first Turing-complete computer (except for memory limitations), but was mechanical rather than electronic. It's existence was kept secret until after WWII.
The first fully-electronic computer was the Colossus. It was designed primarily by Tommy Flowers, with assistance from others at Bletchley Park. Its was also secret until after the war. (It was used to crack the German Enigma cipher (code) machine.) It was programmable only by rewiring it, and was not Turing-complete.
I think the ENIAC, designed by John Mauchly and J. Presper Eckert, was the first computer to be both Turing-complete and fully electronic, but I'm not sure. It was considered the first programmable computer until information on the computers secretly made during WWII were made public.
The first computer with a graphical display and mouse was the Alto. It was created by a small team at Xerox, but was never sold. Some consider it to be the first personal computer.
The first computer to use an x86 processor was the IBM PC 5150. It was designed by a team of engineers led by Don Estridge.
Charles Babbage designed what was called the "Analytical Engine" which was the first stored-program mechanical computer in 1837. However his design was never completed.
In 1939, John V. Atanasoff and Clifford Berry developed the Atanasoff-Berry Computer at Iowa State University, which was regarded as the first electronic digital computer.
The first computer to have the components necessary to be considered a computer was made by Konrad Zuse in 1936, it was called the Z1, with its successors being the Z2, Z3, and Z4 respectively. While many think the first computer was the ENIAC, the ENIAC was only the first electronic computer, with the Z1 being mostly mechanical but with a drive motor to facilitate somewhat autonomous calculation. It was different from being simply a comprehensive calculation machine in that it could operate from a program and execute commands autonomously vs just react to given instructions.
What is another name for personal computers?
It was called PC. Notebooks or Desktops. Some people PC in a bad way though.
What was the first computer made of?
Well some parts of the computer is made out of medel and some are plastic and copper. Well some parts of the computer is made out of medel and some are plastic and copper. Well some parts of the computer is made out of medel and some are plastic and copper.
Did Hitler die before or after world war 2?
Hitler died a couple of weeks after world war 1. He shot him self and bit on a a poision pill.
Adolf Hitler did not die he commited suicide. It was on April 30th, 1945 Adolf Hitler shot himself with a pistol. He had a suicide pact with his wife that she would take a pill and he would shoot himself. They did this because they didnt want enemies to have the joy of killing Hitler.
How many components make up a computer?
You're kidding, right?
Just in case you're not, it depends on the computer. The hundreds of millions of transistors could be called components. The monitor, keyboard, disk drives, motherboard, power supply and peripheral hardware each have many chips containing an overwhelming number of transistors each.
You'd have to research each component used in a specific computer, perform a chip count, and while you're at it count all of the other components. Since each manufacturer has different ideas of what's the RIGHT way to build a computer, each computer will have a different count. But feel free to start the research.
Just one typical 1G byte RAM package has nearly 10,000,000,000 transistors (components) and about 8,000,000,000 memory capacitors (components) on it. A modern Microprocessor, Bridge Chip, Drive controller, etc. has similar numbers of components on it. Most chip manufacturers will not release actual component counts of their products as it is considered proprietary.
How powerful was the first computer?
Calculations. More specifically, addition, from that even computers now days just use addition. For example, when you want to subtract something, it just adds a negative amount. When you want to multiply, it just adds that many times. For division it sees how many times it can "subtract" then shows the remainder as a decimal.
How many computers are made a day?
Estimates per quarter (of a year) generally sit between 80-100 million units for prebuilt systems. (see source for an example)
If you divide that by 3 to get a single month, that gives you 27-33 million a month.
If you divide that by 30 (an average month) you get between 900,000 and 1.1 million a day.

Computers were made to do the very tedious computations of everyday life and business. The first calculators performed computations in seconds that would take someone using a slide rule minutes if not hours to do. Calculations for NASA entry and exit trajectories would take days or even weeks to calculate by hand and the first mainframe computers would do the calculations in minutes. Hope this helps you. cblair91: the first computer was used to crack the german code in world war I and ever scince then they have become famous and then NASA started suing them, later in the line microsoft came in and started making them to sell to houses and industrys.
How did computer become such an important part of your lives?
the computer is important because there is internet and we can search for things
What is the brain of the computer called?
The "computer" part.
Humans have built computers with our understanding of cognitive science. Computers implement a processor, memory for temporary data storage (during processing, caching, etc), and a hard-drive for persistent data. A human brain can store data long term, process information, and temporarily hold small amounts of data for short times while processing the information (e.g. "Carry the 2...").
Which company placed the first computer on the market?
- in the UK, Lyons Biscuit & Tea: LEO (Lyons Electronic Office)
- in the US, Remington Rand: UNIVAC (UNIVersal Automatic Computer); Note that this machine was designed and announced for sale by EMCC but they were about to go bankrupt and default on all their contracts when they sold the company to Remington.
- in Germany, Zuse: Z-4
All three of these companies are possible candidates as they designed computers and announced them for sale in the same timeframe. Other companies all entered the market after these three.
I suggest you take it from here and determine which of these was actually the first yourself.
The 3 main points are:
- Unauthorised access to computer material: it is unlawful without proper authority to: use anthoer person's ID and password to access a computer, use data or run a program, alter, delete, copy or move a program or data or simplay to output a program data, lay a trap to obtain a password.
- Unauthorised access to a computer with intent to commit or facilitate the commission or a further offence: this covers the situation where unauthorised access is gained with intent to commit a further offence, eg a person may gain unauthorised access to computer material to commit theft by re-directing funds from someone else's bank account
- Unauthoried modification of computer material: this offence includes the deliberate deletion or corruption of programs or data includes the creation of viruses where these results in the modfication or destruction of data.
Most general purpose computers support multiple users simultaneously. Pretty much anything that runs Linux, Windows, or Mac OS have this capability.
