Computers

If you made a boot disk, use it. Otherwise, get out your system disk and reinstall the system. This time make a boot disk. If it still does not work, take it to the shop. You may need a new disk drive or something more. Something may have worn out or been fried.

A LOT of people, but the first ones were Charles Babbage (1791 to 1871) was the first to design and build a "working" computer (it was full of bugs, but he was right, years later it was finished and it worked just fine.) It was mechanical, but he had plans for one that ran on steam power.

Then there was his lady friend, Ada Lovelace (of literary fame), who was the first programmer.

And George Boole (1815 - 1864) who proposed the math that EVERY modern computer depends on.

The internal hard-drive, USB flash drive, external hard-drive can all be used to save data, provided the document (for example) has been saved occasionally while the document was being worked on. If working in RAM (Random Access Memory) the data is lost as soon as the power is turned off, as RAM is a volatile memory, unless a battery back-up system is used.

Depends on the computer.

Input devices are something that gives the computer information.

e.g.

Keyboard

Mouse

Webcam

Microphone

TouchPad

Graphics Tablet

If a customer has a complaint you should act with sympathy and politeness. Make sure you apologise and make the customer feel valued, tell him/her that you will tell your boss to make sure the problem is solved or if you can solve the problem then do so. Ask your boss for more advice though

That is called an IP address, and is made up usually based off of location, and your internet service provider (ISP)
IP address is the logical address which serves as Identity for the Host device on a Network.

It can do lots and lots of things, such as access the Internet, perform hugely complicated calculations and run video games. It cannot do physical tasks such as making your breakfast or watering your garden.

Nothing, well a tablet needs a touch sensitive screen, because you do usually not have a keyboard and mouse.

A laptop has a keyboard and a pointing device, but can have a touch sensitive screen, and this screen may also be made so that it flips over and cover the keyboard and the pointing device - as on a tablet.

I led a company that discovered it was cheaper to make prototypes of tablets using laptops, so we bought spare parts for a laptop, fitted a touch sensitive screen to this, with a driver that made it look as if it was the good old screen, coded a keyboard for the screen, and had a demonstration unit that we did not have to design and prototype in China, could make one in the laboratory and fit in our own casing, power supply and batteries. Showing it to prospective buyers worked fine, they did not demand to see the internals.

I see that Android tablets can easily be equipped with both keyboard and mouse, and also the iPad. some of these keyboards are in the cover, so attached to the tablet while this is protected. So maybe the difference is that a tablet can a laptop, while most laptops cannot be a tablet?

The purpose of the priority level is for when a program is taking a long time to finish a job/command, you can change to a higher priority; or if a program is maxing your CPU you can lower the priority so other processes can run more proficiently.

Yes, this is good quantity and quality. Knowing the manufacture of the RAM listed above would be required for a more in depth answer.

Most likely, you mean silicon. It is certainly used in computer chips, glass, and abrasives.

No such thing as a virus disabling keyboard. You need to check the pins where the keyboard connects. One may be bent over. If that doesn't work enter bios and enable keyboard. Last but not least unplug all the toys you have connected to the computer "while it is off" and try turning it on again. You have a conflict.

Because a video clip contains far more 'information' than an audio clip. Video contains sound AND picture, if you will, while audio is only sound. There is probably four to five times more data in a video clip than a similary timed audio clip.

The main component of eggs is water.

Depending on the complexity of the task, such as Predicting the Weather one may use a super computer for the task. For a simpler task such as hosting a website a server would be better suited.

geographers use computer-based systems called what to connect information with locations.

A person who has basic computer skills can be described as "computer literate". This can be described with variety based on whether one has computer skills on Mac or PC operating systems, and which programs they are well-versed in.

Practical Computing was created in 1978.

Google.com is an American based internet search engine. Like hoover is often used commonly for a vacuum cleaner (despite Hoover being a trade name, for their range of vacuum cleaners), so Google has become the common advice to: Google It!

There are many places one might purchase used computer books. One may use websites such as eBay to purchase used books for low prices. One may also visit local second hand stores like Half Price Books that carry these books.

Usually a device driver facilitates communication between a device and the OS. Device drivers are written in low-level languages such as Assembly or C.

System bus speed in microprocessors is the speed at which a processor sends/receives data from the motherboard's memory controller. It is also called the Front Side Bus (FSB) speed in the case of Intel CPUs.
