Well obviously you had to use a computer to ask this question. A computer makes it easier to search for and find information. Computers have also revolutionized the way we communicate. They help us to store and play music and videos. Now they are making all of this possible on cell phones and such, but computers are usually faster and they obviously provide a larger screen and the computer can multitask. The quality and efficiency is overall better than any phone (unless of coarse you have an outdated computer or dial-up internet or both.) The computer also allows you to play large video games (Counter Strike, Runescape, etc.)

To answer the question that was first asked about how computers help with criminal

investigation.

Computers are used between police agency's for information on records and personal info. They are also used to create a face of someone that was seen by a witness.

Programs such as face gate and several face reconstruction programs.Police also use filtering software to catch child porn criminals.

That's called a network - If they're all in the same building it's a local area network (LAN) - If the computers are spread over a number of buildings independent from each other, that's a wide area network (or WAN)

A Laptop/Computer has two types of memories. 1> Hard Disk- Which is a memory with higher storage capacity ranging from 40GB to 500GB easily available right now. This is a permanent memory( will not be erased when you shut down your laptop) will help you store more of your files, songs, videos etc and depending on your need you may select a configuration . I personally prefer 250GB + and buying a portable hard disk of 500GB 2> RAM: Or Rapid Access Memory. The processor uses this as a intermediate storage location or desk area between the hard disk since RAM is much faster to access than the disk( RAM is a temporary memory and automatically erased on shutdown or rather we can say session specific). The bigger the RAM, better the performance, more simultaneous applications can be run with ease! Currently 2GB is the norm but I would suggest 4GB with expandable capacity upto 8GB. This is one area where one should not compromise.

There is one very simple way to find out if your computer is running the 32- or 64-bit version of Windows Vista. First, navigate to your start menu. Find the "Computer" icon and right-click it and then click the "Properties" option. The version of Windows you are using will be next to the words "System Type".

as long as they are baking.

first you have to have a cable for cellphone to computer then you can actually copy paste it to the phone. simple as that. In addition to the above, some phones have proprietary software that also must be purchased in order to access the phone.

First of all ... Megabytes is a unit of information used to measure the information capacity of various components in a computer. Your question could mean many things. I would assume you either want to know how to add memory (simultaneously running programs) to your computer, or how to add to your computers total storage capacity (file storage).

As for memory, you can add to its capacity by buying RAM, make sure that you have bought RAM compatible with your computer first.

As for storage, you can add to its capacity by either removing unecessary files in your computer, or buy a new hard drive. Make sure that you check your computer for a spare SATA or IDE connection first and that you buy a hard drive that is compatible with your spare connection.

It houses the motherboard, hard drives, power supply unit and other components.

the computer is brain mental power thinking extra knowledgeable of develop.but computer new idealistically successful in together brain. first safe for computer in Ur home use , traveling the car etc. the brain sub dividend for round safe in the head. so computer is brain so automatically work it do brain equal for computer. that the my point........... thanks

Both, depending upon it use. An analog camera (like an old Polaroid) is strictly an output device only. However the new digital cameras can act as motion detectors and other types of security related devices with the ability to programmaticly interact with its environment - in this regard the camera is both an input device as well as an output device.

Added:

Additionally, any camera with a digital format can act effectively as an input device, if it connects to the computer via USB. (You can upload pictures directly to the PC, thus input)

You'd need to be a lot more specific. Are we talking a simple file/print server for your home network here, or do you plan on running a web service for 100,000 clients on it?

At the low end, you can reuse an old computer for a server (cost: effectively free). A high end multiprocessor server with terabytes of storage could cost tens of thousands (and if what you're doing is important enough to spend that much, you'll probably want at least three of them... one for development/testing, and the rest for load splitting/failover).

The website of Newegg has very good computers available for purchase online at good prices. Searching through eBay and Amazon would be very useful and amazing deals can be found sometimes. Radioshack is a very good in person store to find laptops and computers for good prices as well. They have deals and special offers on computers sometimes because of their local presentation.

Password's and ID's are generally encrypted after being set. You are unable to view account passwords and other possibly sensitive information for if someone else got a hold of that computer you would not want them to do as such.

104 or depending on the computer 106 or 107 and there more but i dont have one to count

A byte is a standard "block" of data bits that was introduced by IBM and other manufacturers to store one "character" or "symbol" or some other standardized piece of data. A "bit" is the short name for a "binary digit" that can have only two values: 0 or 1.

1 byte is usually defined as 8 bits.

1024 bytes = 1 kilobyte

1024 kilobytes = 1 megabyte

1024 megabytes = 1 gigabyte Note:

All the above definitions have long been in common everyday usage within the computer industry.
