What are the negative impacts of computers?
Whilst there may be many positives to be had from computers such as increased mathematical problem solving and generally making tasks easier there come some down falls:We spend a lot of time sat down at a computer. It can be bad for health if don't balance this out with regular exercise and healthy eating.If you constantly stare at a computer monitor it will deteriorate your eyes and you may need glasses.Constantly typing and using a mouse can cause injury.If our posture is not great whilst sat at a computer it can cause back injury. We lose a certain amount of social, human interaction when we rely on computers too much. This can make us antisocial, less confident and lazy.Whilst production can be done more effectively in some roles by computers it means a loss of jobs in some sectors.
Which career lets ypu build computers ?...?
If you are taking about designing motherboards, processors and computing hardware then this field is Computer Engineering. It involves Programming and advanced Math. You would want a Computer Engineering Bachelors Degree to work in this area. If you are talking about building and administering Computers and Networks then that would be Systems or Network Administration. You would want to get a Computer Information Systems (CIS) Bachelors Degree or its equivalent. If you are taking about fixing computers and troubleshooting problems this is a Computer Technician. This would likely also take a CIS Bachelors Degree but you might be able to at least start out with an Associates Degree. If you are interested in working in the Computer Tech area these are some limitations in this career. Hardware is the way that many of us got started in IT. We started out working on our own computers and soon were the official computer repair person for other family members and friends. However, we quickly learned it is not really that great an area for advancement. You see on the desktop and server side, attitudes have changed in how we look at hardware. On the desktop side of things it used to be that desktop technicians would go out to the customer's cubicle and work on their computer taking as long as it took to replace motherboards, hard drives, etc. Even if it took a few hours to fix they would do that. These days if the repair takes over a few minutes the technician will just hand the user another computer and start the transfer of data and be on their way in 15 minutes. Many businesses have switched to a very large percentage of laptops to make this replacement process easier. They will set up service center manned by a very small number of staff who service users bringing their computers to the center for service. On the server side many of the nodes are virtual machines and there is really not any hardware connected with a given server - just some large hosting hardware. So the idea of doing hardware related stuff is great for the short term but will be limiting for you in the long term. You will want to work towards getting into Computing Security, Networking, Systems Administration, Programming and other IT areas. Best wishes!
Any jobs that let you build and put together computers?

So the idea of doing hardware related stuff is great for the short term but will be limiting for you in the long term. Consumer stores like Best Buy and Staples or small local retailer will hire computer technicians to do repairs, virus cleaning and upgrades but with the prices of computers, tablets, laptops and ipads getting so low many times people will opt for replacement rather than spend money on repairs.

They say that today's cell phones have more computing power than NASA used to go to the moon in the 1960s. If that's true and assuming I have my own rocket, what apps would I need to make it from Earth to the moon with just a phone and a rocket?
well, this is something i really like to know, so i googled it.based on computer world, Apollo 11: The computers that put man on the moon , the Apollo Guidance Computer (AGC) had approximately 64Kbyte of memory and operated at 0.043MHz."The importance of this computer was highlighted in a lecture by astronaut David Scott who said: "If you have a basket ball and a baseball 14 feet apart, where the baseball represents the moon and the basketball represents the Earth, and you take a piece of paper sideways, the thinness of the paper would be the corridor you have to hit when you come back.""Along with the APG, mainframes were also heavily used in the Apollo programme. Over 3,500 IBM employees were involved, (pictured below). TheGoddard Space Flight Center used IBM System/360 Model 75s for communications across Nasa and the spacecraft."and here is the IBM System/360 based on Wiki, and Model 75 got CPU Bandwidth of 41 and Memory of 1,024KB.on the other side, Apple mobile application processors, A4 (for iPhone 4) is running with 800MHz and 512MBi think this gap is quite big, since only a few guys i know are still using a 2010 phone. and i am sure you have more power in your hand.so the force is with you, use it.
Why was the computer invented?
The time when computer were not there , people did use to do lot of things by themselves, given they had enough time, which included calculations. apart from the everyday mathematics , they used to calculate a more advanced type of arithmetic and algorithm, which is almost impossible for 99% of computer users today.the inventor of the computers (and my greatest inspiration) Charles Babbage must have realized the idea of solving them much faster than ever before(as for them it might have been used as a calculator), so there comes our first generation computer, which had no mouse no screen and no keyboard. So what did it had?the answer was vacuum tubesit contained large data banks and vaccum tubes.the cpu, almost the size of a room at that time use to give answers in a fraction of second.but the thinkers never stop,they thought that the sole purpose of a computer is not only to compute but to make the tasks of a user much simpler.so the CUI was invented to ease the using of computer(using first generation computers was hard).then finally comes our 4th generation computers , the simplest and fastest of all generations based on GUI are a boon to our world , and we dare not do anything without consulting from our assistant .Hence, we know computers were built for computing but a better definition would be to convert complex calculations to simpler answers.
Does IBM still manufacture any computers for which EBCDIC is the primary character code set?
The person who wrote the above answer hasn't ever heard of IBM mainframes. IBM still manufactures and sells mainframes today, and its a $3 billion a year business for them. The primary operating system for IBM mainframes is z/OS, which does support EBCDIC. They are also capable of handling ASCII and Unicode. Also, z/OS has gained many "modern" features, including running Java, UNIX applications, Linux applications, and the ability to communicate via TCP/IP and to Web-based systems.
Who should I buy a computer from? MDG or Dell?
ive had an mgd computer it runs fine even tho its 4 years old and del like this lady just said dosent offer software support only hard ware and even that limited dell sucks mdg is wayyyybetter
