What is a computer?
A computer is a biological and/or mechanical device that computes or that performs computations. One of the earliest computers was in fact the human brain; the ultimate in biological computers (as far as we know). But for a very long period of time, a computer was simply a job description; one who computes.
A thermometer is also a computer. An analog computer. A mechanical device that serves a specific computational purpose. In this case, to accurately measure temperatures. Clockwork timepieces and slide-rules are also examples of analog computers. The list is endless. However, when we think of computers today we often think of digital computers. So let's begin there.
What is a digital computer?
A digital computer is a mechanical device not unlike an analog computer (they are both machines that compute), but they differ in one key area: they have a dynamic memory. That is, they can store data as incremental values, or digits, hence they are called digital computers. Moreover, unlike an analog computer, they can be programmed to perform many different computations, including computations that have yet to be conceived.
The parts of a computer
The basic components of a digital computer can be broadly broken down into two main categories: hardware and software. Hardware is the physical component while software is what brings the hardware to life and gives it purpose. You cannot have one without the other.
The hardware can be broken down into several key components: input devices, processing devices and output devices. The input and output devices are fairly self-explanatory, but usually consist of a keyboard and screen at the very least. With modern touch-screen technologies, however, the distinction is becoming less apparent but, suffice to say, they are both an input and an output device.
The processing devices consist of a central processing unit (CPU), random access memory (RAM) and mass data storage devices (usually hard-drives). The CPU does all the real work, however all three work together. The hard-drives store all the software (programs and data) that is to be used or created by the processor. Programs and data that are currently required by the processor are loaded into RAM, and the processer executes the programs one instruction at a time, referring to the data stored in RAM. Depending upon the program, additional data can be loaded from the disk while new data can be written back to disk, as and when required.
RAM is an extremely volatile form of memory in that it requires electricity to maintain its state. However, it is extremely fast and can be modified at an extremely rapid rate. Mass storage devices like hard-drives are non-volatile however they are many times slower. They do fail from time to time, but they do not require a power source to maintain their state.
Although hard-drives can fail, multiple hard-drives can be combined such that data is duplicated automatically. Thus if one drive fails, another can be used until the faulty drive is replaced. This is known as a redundant array of inexpensive (or independent) drives, or RAID. There are various configurations depending on whether you want automatic backups or enhanced performance.
The processor, RAM, hard-drives and all other peripheral devices (screen, keyboard, printers, etc) are all connected together via a motherboard. The motherboard also has its own small non-volatile memory chips known as ROM (read-only memory). This contains a small program (the BIOS, or basic input/output system) that performs a series of quick tests to ensure the primary hardware (e.g., the CPU and memory) are all working, before passing control to the boot loader which is stored stored on disk.
Can you erase a virus from a program and still use it?
There is away. there are some free online scanners out there to scan your computer but cant delete them. they should tell you where the virus is hidden. go to search and look in everything and make sure you set the advance seting to seearch hidden files and folders. once you find the infected file delete it from your computer. make sure you empty your recycle bin. BUT! if a virus is hidden in a pathway you need antivirus or to reformat your computer. deleting viruses manualt may harm your computer
What is the average price of a Lenovo Computer?
According to the Lenovo website they make a variety oflaptops that start at about $380 and to to up to $630for a 15.6 inch monitor, and also make Pentium and Core models that are within the same price range.
Computers are famous for many reasons such as Globalizing the world (bring it closer together), creating a more complex department in life such as new medical discoveries and advanced, complicated databases of various data such as shares and business work which can be retrieved in the blink of a second compared to days even weeks when everything was on paper. Computers have allowed for quick communication between citizens, governments, businesses etc and have allowed a world of education to be available. They help the rest of our technological department such as programming to build things such as cars or cut trees for furniture etc They are the most known piece of technology and come in different forms such as a mobile phones is liek a mini computer, Desktop computers, Laptops, Portable gaming systems such as xbox or gameboy etc even inside the cockpit of a plane. They are used in the majority of everyday people and are therefore well known and famous.
What information does a computer processor serve?
At first. Computer has few processors:
Central processing unit (CPU)
Graphics processing unit
Sometimes
Physics processing unit
Digital signal processor
Network processor
Front end processor
I believe you ask about CPU. The CPU plays a role somewhat analogous to the brain in the computer. The term has been in use in the computer industry at least since the early 1960s.[1] The form, design and implementation of CPUs have changed dramatically since the earliest examples, but their fundamental operation remains much the same.
When was The Art of Computer Programming created?
The Art of Computer Game Design was created in 1984.

What is the meaning of ram in a computer and how it works?
RAM stands for Random Access Memory. It is physical memory installed in a computer or storage device as silicon chips, hard disk, floppy disk, CD, etc., that is addressable by, and is directly accessible to, a computer (CPU) in a non-sequential (random) manner.
What is another name for a computer programmer?
There are a number of terms for computer experts, depending on the context. Here are some of the terms:
Computer Expert: This is a general and somewhat formal term for people who are experts in computers.
Computer Guru: A guru is another name for a hacker or anyone with a lot of informal computer knowledge and experience.
Computer Technologist: A formal title for someone trained in computer technologies.
Geek: Anyone with nonconventional interests and interests in technology. The level of interest involved generally means the person will have some skills, even within a narrow scope of computing such as gaming.

How do you brighten computer screen laptop?
After just dealing with this problem myself, I found out my Lcd laptop screen was only at 50% brightness, now its good.
Theres 2 things you can do assuming you mean an LCD screen. Sometimes maybe on a laptop you have to press FN key then hit the keys with sun picture on it etc, to dim and brighten.
BUT... IF that doesnt work, and you make it as bright as it will go and you still feel your laptop screen or lcd monitor just seems kinda ..dim..not as bright as used to be etc.
Then it means your CCFL (cold cathode lamp) in your lcd is starting to go, or its power inverter that runs the lamp. Laptops actually usually only have ONE of these stick type lamps. If you have a certain screen size you can tell what size lamp to order. If you don't know electronics or how to take apart laptop or screen without damaging it, and be realistic. May want to just take it in to have this done, its VERY common problem. And if you do it yourself, you can go on eBay and for under $20 or around there you can buy a new bright replacement. Or call around for cheapest service place, but this is something you can do yourself, if youre very delicate, unplug everything including battery.
OH, and actually theres prob a slew of online how to videos to replacing it. If this is indeed what you meant. But may help others too.
Are computer cookies bad for you?
Internet cookies can be bad, as they are the little spies that keep up with your online preferences as well as the contents of your shopping cart before you make the purchase on a website. Think of them as your Tivo, as tivo keeps up with what you watch, and what you are interested in, and from there, it tapes similar shows, which after a while, can tell you what you are really like. This can be scary and unnerving, though cookies are worse, as you don't get viruses, spam and unwanted junk from satellites or cable tv.

How do you port forward through ethernet (no router)?
First Check your windows firewall setting and check out and make sure you are allowing the ports of the program you need ports open.
most isp's only block certain ports for quratine or bandwidth hogging programs. Blocking Ports is a natural defence against hackers and other potential threats, because they restrict the connection comming into your computer. modems generally don't have such security, therefore it's important that you know the difference between the modem and the router.
Routers are meant to...route the given connection to other computers, The modem is used to dial in or connect to the ISP for the connection and the initial IP. Most linksys routers have the default 192.168.1.1 as it's setupIP and username nothing and password admin. As for other routers you can find it at the product page or support sites. Also, portforward.com has software and guides to help you find your router.
If you are 100% sure you do not have a router, it means that your ISP has one that shares the internet , you can find the router but you can't log in because you don't know the router user name and password...
