No doubt,the use of computer has lowered human labor lots and lots The work which required much time before can now be done simply within fraction of seconds.This is one of the main cons of computers.Sitting in a room and controlling world has now become possible due to discovery of computers.Communication has become possible due to internet.Information can be easily gained through internet.Globalization has become possible due to computers.

Computers are used in each and every sector.From offices to school,from colleges to houses ...everywhere it is used.Even in defense system it is used.In hospitals to keep record of patients,to find symptoms of various diseases its been used.Similarly,it is been used for entertainment by teenagers.Likewise,it is been used as source of education.Distance education has become possible.So, these are the advantages of invention of computers which might make us think that they are very useful.But one thing that must be kept in mind is its negative aspect too.

The question is very vague. The cost of a mini laptop must be different because of its different brands models and configuration. For example, the price of acer aspire mini laptop is $352.99, but The HP Mini with Mobile Broadband Built-In is $199.99 . So you should decide which brand or configuration to buy, and search some related information.

In reality a computer is an electronic calculating, storage and display device that can only calculate answers or store information using 1's and 0's (Ones and Zeroes) and no other numbers! That is the reason behind the RAM-sizes, 1024, 2048 etc... But computer system designers are quite clever at concealing that fact, giving todays computers almost a 'real, lifelike' feeling.

Searching websites for software such as Norton or Mcafee provides free desktop security software trails for a certain amount of days and if it works out well you can buy the software online or at any convenient computer store.

The general idea is that with any clustered machine a terminal or node that the user operates on issues a task using the MPI or an equivalent protocol on all the nodes.

A good price on a desktop computer varies from what you will be doing with the computer, if the computer will be used for normal office work then the price range should be from $200-$400, and could easily be bought from Stores such as Best Buy, Tiger Direct, or Office Depot. Otherwise, if you want a performance computer powerful enough to run the top new games and perform multiple tasks, then you're looking at a price range from $500-$1000. If you want to a performance computer like this, then it is best to buy the parts and put it together yourself. You can buy parts from sites such as Newegg.

If it's your younger brother, under 7, say " If you touch the computer, all the ghosts in the house will come and take you back in time and you'll never get to play again. EVER! You'll be a slave to the ancient Amazons!" If it's your older brother, password block it.

Assuming that you are using the Microsoft Windows operating system, there is usually a red 'X' in the upper right hand corner of the window that you would like to close.

Yes, you can connect a PC wirelessly to a DSL connection. You will need a wireless access point/router and connect that to the DSL modem via USB or ethernet. Configure your PC to attach to the wireless access point/router using the wireless (802-11a,b,g) or eithernet.

Yes, Dell currently offers different models of gaming computers such as the Ultrasharp Flat Panel Monitor. Along with that, the company manufactures gaming keyboards and speakers and other accessories.

Frequency of the processor determines how much elementary binary operation it can make. Computer does not need to focus attention and makes exactly what he is asked for. If you could input data at the same level of integration to your brain it might be even faster but it is impossible.

No.

The computer uses a lot of power when first booting, but this only lasts a couple seconds before it reduces considerably. It will reduce further when the system is on and idle after booting.

The amount of power saved by turning the PC off for 5 minutes is equivocal, approximately, to the power used in 1 minute of it being on and idle.

An idle PC uses typically 80 to 400 watts of power. And a PC that is off uses typically less than 10. (If unplugged, none at all.) A PC on and in-use, such as gaming, typically uses 150 to 2500 watts, varying vastly.

These figures are for desktops. Laptops use less power overall. But it ALWAYS uses less power to turn a PC OFF, than to leave it on.

I would say if you want a bundled plan with local and long distance calling, you will normally pay $50-60 per month. If you have broadband internet you can get home phone service with Free Long Distance for as low as $14.95 per month.

Very little is stored in it - mostly, that's the job of RAM (read-only memory) for short-term storage or the hard drive or other more permanent medium. CPUs do have relatively small registers that store numbers for long enough to work on them. However, the main job of the CPU is number crunching.

An advantage is that we use computers everyday for pretty much every aspect of human life. A disadvantage is it is making the human race more lazy.
