Computers

Right now, none. Some animals, chickens, dolphins, and gorillas have interacted with computer peripherals (lights, switches and other things controlled by a computer) , but they had no concept of anything about it - software, systems, saving stuff, opening stuff, all beyond them.

A set of electronic instructions that tells the computer what to do is called a program. Programs are essentially algorithms to a solution that are written in a language the computer can understand.

The CPU is a central processing unit. The GPU is a graphic processing unit. They control the visuals you see on computers, cell phones, tables and video game consoles. They work like a CPU to process data and information but instead of working with hard data they are processing images.

MPEG-4 file extension used for videos downloaded from the Apple iTunes store; includes TV episodes, full-length movies, and music videos; similar to an .MP4 file, but may be copy-protected using Apple's FairPlay DRM copyright protection.

To play a protected M4V file, your computer must be authorized (using iTunes) with the account that was used to purchase the video.

Unprotected M4V files may be recognized and played by other video players by changing the file extension from ".m4v" to ".mp4."

So if you want to play M4V files freely, you need a 3rd party tool to remove the DRM, try M4V Converter PLus, it can help you.

In a simple timeshare operating system all processes receive a time "slice", meaning that a process can run for a specified amount of time, typically measured in fractions of a second.

In a simple realtime operating system, all processes are assigned a process "priority" If a process is ready to run and it has a higher priority than other processes, the process has control of the CPU until the process gets to a point that it is no longer "ready". That can mean that the process is waiting for I/O or for the completion of some event. If multiple process with higher and equal priority are "ready", the CPU is typically shared between them, using some kind of timesharing.

Most of todays operating systems use a blending of the concepts.

The best brand of printer ink cartridges really depends on the type of printer you are using. For example, if your printer is HP then you will need to purchase an HP ink cartridge for your printer. Occasionally you can find generic brands, but as a rule, the warranty is only valid if you use the specific ink for your printer.

The three components that must have the same form factor in a computer are the case, power supply and motherboard. The case should be able to support the form factor of the motherboard and the motherboard should be able to support the CPU socket type.

the press of a button activates a switch, connected to this button (in fact - the button is the switch). This allows electricity to flow and refer to the memory cell, with which this button is connected. Then the information from this memory cell comes to processor via control device. The control device sends it to processor's input device and processor processes it with the processing unit. After processing the information becomes a command and then the ALU (Arithmetic Logic Unit) in processor performs it. After a command is executed it becomes an information to display on computer's monitor. The information goes to the output device in processor and then flows by bus to VGA. VGA shows the image on a monitor.

The original floppy was an 8 inch, single sided disk first developed in the late 1960's as a result of research efforts by IBM. The first floppy disk drive systems became commercially available in 1971. They cost more than a new PC costs today.
The floppy disk was introduced in the 1970's, and it revolutionized data storage in the PC. It ran strongly for some time, but faded in the 1990's. It is rare to see a working machine being used in this day and age with a floppy drive in it. Wikipedia has more information, and you'll find a link to their post just down the page below this answer.
1971
According to wikipedia; IBM introduced 8-inch floppy disk (read-only) in 1971...

state four elements of posture that you should check while sitting at your computer

Most laptops are fitted with a touch-pad rather than a mouse. However, Windows software is usually capable of recognising when a mouse has been plugged into a USB port, and will set up the necessary drivers.

ROM stands for Read Only Memory. It is used to hold data / information in a computer that isn't ever going to be changed. Most modern computers don't use ROM chips any more because the data held cannot be changed when bugs are found. Smaller electronics devices (especially toys) quite often use ROM chips to hold a computer program / sound effects etc etc.

on skype u can do a video chat. also if u chose u can type your message instead of saying it. also there is a mute button so u can still see the person but they cant hear u and u cant hear them. i recommend skype to anyone with a webcam. if u love MSN u will love skype.

Because they can store a lot more information. And they're faster.

A gigabyte is 1024 megabytes. Therefore 136 gigabytes is equal to (136 x 1024) Megabytes; this equals 139264.

Any website that sells a Hewlett Packard laptop will have reviews by customers. Amazon, eBay, Walmart, Target, Newegg, Best Buy, Fry's Electronics, Tiger Direct, you name it. Sometimes CNET has reviews.

Computer form factors are regulated sizes, dimensions, and power standards (especially with power supplies) to ensure compatibility and modularity should the occasion arises when a part requires replacement or upgrades. Usually the case is that a computer chassis will support any smaller form factor parts in its series unless specified otherwise (e.g. EATX cases will hold EATX, ATX, and smaller, while ATX holds ATX, microATX and smaller).

A document is a form of information . A document can be put into an electronic form and stored in a computer as one or more file s. Often a single document becomes a single file. An entire document or individual parts may be treated as individual data items. As files or data, a document may be part of a database . Electronic Document Management (EDM ) deals with the management of electronically-stored documents.

When using certain computer application programs such as a word processor , a document is the unit of saved work. Each document is saved as a uniquely named file.

If 835 million computers were sold between 1981 and 2000 that would average to approximately 43,947,368.42 computers per year. I would assume that as technology had gotten much better since 2000 that that number has probably doubled.

The percentage of Canadians that use the internet is about 79.2 percent of the population. This was as of 2011 so it is possible that it fluctuated a little bit.

If your referring to cat5, cat5e, cat6 wire, what you have is two wires that carry voltage, when voltage travels on wire it creates a magnetic field around the wire, you have two wires that carries voltages and both wires are creating a magnetic field... then you have eddy currents... take two magnetic and bring them close together and you disturb there magnetic fields or crossing of eddy currents as you disturb there magnetic field you feel the resistance or how it becomes harder to bring them closer together. The resistance of the magnetic fields is the same on two conductors they resist flow. So if you twist the two pairs together somehow it helps to cancel or reduce the repulsion of the fields and allow the voltage to flow better or more efficiently. the tighter or more twist per length the better.

If it's running Vista, it will almost certainly run 7. There's really very little reason for anyone to stick with Vista. If it's running XP, it's not as clear-cut, since a machine that runs XP just fine may or may not have the horsepower to handle 7. If you're running anything under XP... then probably not; any machine that pre-dates XP is almost certainly too old, unless you've upgraded it piecewise (new motherboard here, new graphics card there, more memory, and so on).

In the Related Links section there's a link to Microsoft's Windows 7 Upgrade Advisor that will give you some idea of how 7 will work on your machine.

There are currently no well-known tablet computers available with an integrated optical drive, though you can connect an external drive to some devices.
