What is in a computer? well it really depends on what someone does with it. But all working computers have a few simple things. 1. motherboard (main part of computer) 2. processor (this allows the user to actually do things on it and the higher the CPU speed the faster and better it does those things) 3. Power supply (transfers electricity throughout the PC) 4. Ram Chips (Memory transfer station) 5. Hard drive (holds all saved info for later access) 6. video chip (most modern computers come with it built in motherboard but most people prefer PCI/e slot cards for the fact that most cases they are better) 7. chip-sets (this is built into the motherboard but without it your computer will not run)
And that is what is inside a computer. but some people differ from that by adding other cards to the PCI, AGP, or PCI/E slots.
ps. most computers come with a built in sound card but few do not which means you would have to buy a Sound card and fill up a free slot on motherboard.

What is the importance of computer in medicine?
Computers play a key role in almost every sphere of life. They facilitate storage of huge amounts of data, they enable speedy processing of information and they possess an inbuilt intelligence. Owing to these unique capabilities, computers function on levels close to that of a human brain. Computers can hence be employed in a wide variety of fields like engineering, data processing and storage, planning and scheduling, networking, education as well as health and medicine. You might want to take a look at the various uses of computers.
Importance of Computers in Medicine
Computers are the excellent means for storage of patient related data. Big hospitals employ computer systems to maintain patient records. It is often necessary to maintain detailed records of the medical history of patients. Doctors often require the information about a patient's family history, physical ailments, already diagnosed diseases and prescribed medicines. This information can be effectively stored in a computer database.
Computers can keep track of prescriptions and billing information. They can be used to store the information about the medicines prescribed to a patient as well as those, which cannot be prescribed to him/her. Computers enable an efficient storage of huge amounts of medical data.
Medicine comprises vast base of knowledge. Computer storage can serve as the best means of housing this information. Medical journals, research and diagnosis papers, important medical documents and reference books can best be stored in an electronic format.
Many of the modern-day medical equipment have small, programmed computers. Many of the medical appliances of today work on pre-programmed instructions. The circuitry and logic in most of the medical equipment is basically a computer. The functioning of hospital-bed beeping systems, emergency alarm systems, X-ray machines and several such medical appliances is based on computer logic.
Computer software is used for diagnosis of diseases. It can be used for the examination of internal organs of the body. Advanced computer-based systems are used to examine delicate organs of the body. Some of the complex surgeries can be performed with the aid of computers. The different types of monitoring equipment in hospitals are often based on computer programming.
Medical imaging is a vast field that deals with the techniques to create images of the human body for medical purposes. Many of the modern methods of scanning and imaging are largely based on the computer technology. We have been able to implement many of the advanced medical imaging techniques, thanks to the developments in computer science. Magnetic resonance imaging employs computer software. Computed tomography makes use of digital geometry processing techniques to obtain 3-D images. Sophisticated computers and infrared cameras are used for obtaining high-resolution images. Computers are widely used for the generation of 3-D images in medicine.
Computer networking enables quicker communication. Computers and Internet have proved to be a boon in all the spheres of life. In the field of medicine, computers allow for faster communication between a patient and a doctor. Doctors can collaborate better over the Internet. Today, it is possible to obtain experts' opinions within seconds by means of the Internet. Medical professionals sitting on opposite sides of the globe can communicate within minutes by means of the Internet. It is due to computer networking technology that network communication has become easy. Medical practitioners can discuss medical issues in medical forums. They can exchange images and messages in seconds and derive conclusions speedily. They can seek advice and share knowledge in a convenient manner over the Internet.
The importance of computers cannot be stressed enough as computer technology has revolutionized the field of medicine.
How can you learn more about computers?
if you go to askjeeves and type in computer info it will help Computer is an electronic equipment that does arithmetic and Logical calculations (millions of instructions persecond) at very high speeds on the data supplied thru memory. Computers allow the interaction with other computers through communications (TCP/IP). Computers saves & retrieves data from peripheral devices like Hard disks and also allows user interaction with attached Keyboard and displays information on console/monitors.
Can you tell what someone has looked at on your computer?
Not unless they had 'remote access' to your computer while you're connected to the internet. Law enforcement agencies, however, have software able to 'interrogate' your hard-drive - and see exactly what you've been doing up to that point - without knowing your log-in name or password. If they seized your machine - no amount of passwords would stop them seeing what you've been doing.

Where is the BIOS for your computer located?
it is permanently stored on one or two ROM ICs installed on the system board
Cmos setup information are stored in ROM bios chip.and it was maintain by a 3.0 battery.its called cmos battery.
There is a non-volatile ROM chip built into the motherboard that stores and boots the BIOS on startup.
Is 256 MB good for a computer?
Because I can't jump to conclusions on what you are trying to ask, I made some assumptions below:
Assuming you are talking about RAM, it is not enough to run the latest build of Windows or Mac. At least 2 gig is the minimum unless you are using an older OS.
BUT if you are talking about VIDEO RAM, then yes, 258 mb of video ram is enough.
Assuming you are talking about disk space, 258 mb is not enough to handle the latest build of Windows or Mac.
What is the importance of ICT in computer science?
Information and communication technologies (ICTs) include any communication device including radio, television, cellular phones, computer and network hardware and software, satellite systems, etc and the various services and applications associated with them, such as videoconferencing and distance learning.
When applied to computer science, it would help in the development of new software and hardware, mobile applications, etc.

The computer makes it easier for distant friends and family to stay in touch. The computer also enables people to work from home.
What are three hardware and three software components of a computer?
Well, inside the computer, the three main hardware components are RAM (Random Access Memory), The CPU (Central Processing Unit) and the Power Supply (Battery). On the outside, you have the monitor (Screen), keyboard (typey thing) and mouse (What you move the cursor with).
What is an average voltage of computer?
Modern computers consume around 200 to 500 V, depending on your hardware, though this can vary.
What is the advantage of a computer over a robot?
Computers and Computer science primarily deal with the manipulation and storage of data (ranging anywhere from simple text files to larger programs). Robotics deals with using hardware to manipulate the physical environment using programs on a controlling computer to determine what actions are taken.

What are the parts of the computer system that you can touch called?
Hardware.
Hardware(Monitor, Keyboard, Mouse, etc.) are the physical components, software are the applications that run on the computer (Internet Explorer, Firefox, etc.)
How do you find a computer's power supply?
On each Hard-disk, CD-Player, Component of your computer you will find information in as to how many watts of power they consume.
It may be printed on components but more typically in the user-guide accompanying it.
The processor is a separate component of which can draw as much as 130 Watts, although mostly 65-95 watts.
When you have calculated together All the wattage from all different components in your computer, then you know the absolute minimum power your computer can be started with.
A computer these days typically spend 300 watts or more. Only some screen-cards may eat as much as 300 watts. lol
If you have many Hard-disks in your system, then the Watt Drain at start is a lot more than your calculated wattage. This because they consume a lot more when starting to spin up.
In a normal computer system I would not use a power supply that is less than 20% above calculated power drain. Some computer systems with many Hard-disks does not start unless you have 50% more than actually needed.
Is there anywhere that I can purchase a cheap laptop?
Laptops and computer hardware are well priced at Newegg.com
I don't know any American companies that do full desktop systems.
Local newspapers, Ebay. Cashconverters, are three examples where cheap laptops may be found. Also shops selling computers and laptops sometimes have a low cost machine on offer - maybe a last of the line, or display model.. Look out for refurbished machines. Maybe a family member or a friend may have one you can have or buy?
What are the 3 other classification of computer?
