Where is apple computers made?
Most Apple products are produced in China. Apple's headquarters are in Cupertino, California with other offices across the state of California including Elk Grove, California where they design all their products. Most Apple products have a label that says made in China, designed in California.
Binary Coded Decimal. It's a modified form of binary.
10 8 4 2 1. When the count gets to 10 the tens column has a 1 in it.
20 10 8 4 2 1. The tens are also arranged in a binary format. It makes the format more compact.
You should do a clean install. It is not possible to do an upgrade from a 32 to 64 bit O/S. To do this gather all of your installation files (Adobe Reader, Drivers, Programs) and put them on removable media such as a USB thumb drive or Optical Disc. Then make a complete backup of the system. Use a migration tool to move settings and personal files.
What could colossus computer do?
The Colossus computers (1943-1945) could perform Boolean and counting processes in support of cryptoanalysis of secret German military codes, which used various mechanical encoders.
The computers used vacuum tubes and switches set by hand, with data input from a paper-tape loop. A total of 11 Colossus computers were built by the end of World War 2.
The main task of the computers was to find patterns of coded letter substitution that matched repetition and letter percentages, which greatly reduced the work of the main codebreakers. The method was created by mathematician William T. Tuttle and enabled a number of successful code-reading breakthroughs.
Where could one purchase ladies cufflinks?
When shopping for gold cufflinks , it' important to shop around first. Many fine jewelry stores will have a nice selection to choose from and this will give you an idea of what style fits you best. You can also decide on how much you would like to spend on them.
Can a motherboard have more than one RAM?
To answer your question, let's make something clear: there can be four different things meant when you ask about "different types":
- Different technologies: for instance, SDR (Single Data Rate), DDR (Double Data Rate), DDR2 (2nd Generation Double Data Rate), etc.
- Different speeds: within a given technologies, the RAM can be built to run at different speeds: 800Mhz, 1066Mhz, 1333Mhz, etc.
- Different features: RAM designs have a bunch of other properties, depending on their target audience. Things like ECC (Error Correction), being buffered or unbuffered, are the major extra features.
- Different hardware: even if two pieces of RAM have #1 - #3 all the same, it is possible to construct the RAM itself from a variety of different physical chips. For instance, a 1Gbyte RAM module can be made using 8 x 1Gbit chips, or 4 x 2Gbit chips, or 2 x 4Gbit chips.
The short answer to this question (which will satisfy 99% of all computers), is that a computer can use only a single technology and feature set, can use speeds equal to or GREATER than your existing RAM, and can normally use different hardware designs within that technology and feature set.
For instance, the vast majority of systems which are sold as "desktops" (NOT workstations or servers), use a single type of SDR, DDR, DDR2, or DDR3 RAM (these days, it's DDR3, with DDR2 common for machines made in the last 5 years), with the feature set of NO ECC, and NO buffering ("unbuffered"). Very, very briefly around 2000-01, there were some of systems made that had BOTH SDR and DDR sockets - however, only ONE of those two sets of RAM sockets could be used at once, so it wasn't possible to use DDR and SDR RAM at the same time. Systems can use any speed of RAM, but will run at the LOWEST speed of any DIMM used - so, if you have a mix of 800Mhz and 1333Mhz DIMMs, the system runs at 800Mhz.
Please check your motherboard or system documentation. It will explicitly lay out the combinations of the four factors above that can be used in your system. If your motherboard manual doesn't explicitly say it can be used, then DON'T assume it works. If you are unsure, ask your local computer repair store - they'll know for certain.
What are the basic components of a computer network?
A network card, or network adapter as it is sometimes called, allows a computer to connect to a network of other computers. These devices will usually have both a physical layer and a data link layer. Ethernet devices will most often have an 8P8C socket where the network cable can be connected.
Why my computer is making odd noises?
The whirring noises you hear are coming from the fan trying so hard to cool down the PC. This occurs when your PC is heating up as a result of overuse, or multiple programs running at the same time (mostly on the background) when the RAM size or Processor speed is low. Your PC tries to compensate for these lacks and try to keep the PC in optimal condition. When the PC starts making such noises, it's an indication for you to take it for some maintenance. The fan also needs to be clean. It can also happen is you are using the PC in a particular place of increase environmental temperature. I remember how once I had to keep my laptop in the refrigerator to cool down (lol). Another reason why the PC might be making such noises is if it fell at some point.
Will there be help available setting our computers up?
Yes. Just call the store that sold you the computer, and ask them for help.
How do you download free apps on your ipod touch?

How do you copy things from computer to usb?
By a pen drive I'm guessing you mean a USB flash drive like thing. When you plug the pen drive in, your computer should automatically detect it and open up a window that has its contents. Leave that open and find the file that you need to move onto it and just drag and drop it into the Pen Drives window. Its as simple as that. Then close the window and disconnect the drive.
Where can one find information about computer networking hardware?
There are plenty of websites which offer information about computer networking solutions such as Brennan IT and Geeks2U. Alternatively, one can visit your local computer retailer for specific advice.
Which to parts of the computer needs a fan?
The computer itself has fans in, not the components.
The fans circulate air through the computer cooling the parts so they don't overheat. In older computers, the power supply was the main source of heat and only the power supply would require a cooling fan. Later computers had an additional fan on the box frame for heat generated by components. As computers became faster and used more power, some components generated so much heat that they needed additional fans. The CPU chip(s), GPU graphic processing units and some other components have fans attached to them to keep them cool enough to operate without being damaged by the heat.
Dell how many computers are made in day?
The word computer encompasses a wide range of electronic processors, which are found in about half of the things you can see right now from your desk.
Millions of computer chips are produced in a day.
If the question is how many computers the company dell makes in a day, first I'd recommend going back to elementary English, but then I'd say that dell doesn't actually make computers, they outsource production to Asian countries who make computers and ship them back to the states, where the dell logo is added. Your low quality generic computer made for idiots is a product of slave labor. I hope you're happy.
What steps are taken to maintain the software inside a computer?
Install all updates required
Install only licensed programs
Don't install different versions of software
Let IT know when hardware isn't working
Don't download programs from internet sites you don't trust
Be aware of suspicious emails
Use online support resources
Were Can I Purchase A Mobile Laptop Desk?
A car laptop desk or tray can be found at retailers such as Wal-Mart and Target. You can also look for them on Amazon, such as the one shown on the following link: http://www.amazon.com/Kurgo-LAPTOP-AUTO-TRAY-TABLE/dp/B000KPGMUW
What are the main functions of heat sink?
The main purpose of a heat sink is to expel heat from a generating source. Heat sinks work through the process of conductive and convection heat transfer. Heat sinks are a passive form of cooling, as they have no moving parts and require no power.
How do you make computers run faster?
Take it to a computer shop and ask for more RAM or a better CPU. They can install better items that run faster in your computer. You could also scan for a virus, or you could defrag (compress) your hard drive.
What tools would you use to block the installation of unsigned files?
Depends on your OS. In Windows Vista and Windows 7, it will request permission before instaling anything. The request has a drop down menu with details about the program or driver that is wanting to install. If it is something you do not want just click no and it will not install.
Standard that permits file uploading and downloading on the internet?
FTP (File Transfer Protocol) is an Internet protocol that allows file downloads and uploads. Other such internet protocols are torrent and P2P.
What is the purpose of a USB computer microscope?
With a USB microscope camera, one can take images as one would do with a standard webcam. The camera is a high powered macro lens and relies on LED light within the lens. These cameras usually offer greater depth and magnification. One use is in endoscopy.
Is it best to turn off your computer when not in use?
Most computers have a sleep mode, the computer can be set to sleep after a certain amount of time with no use. However, energy is still being used so you will paying for electricity when it's in sleep mode.
If your computer has been on a long time, EG many hours or days, programs may start to run slowly, become erratic or eventually crash but by shutting down or restarting your PC regularly when it's not in use will enable the computer to operate more efficiently. Programs generally run faster and crashes and freezes can be reduced or eliminated by shutting down or restarting the computer when needed or on a regular basis. But these are not the only benefits.
The components inside a PC have a finite lifespan which means they can and do wear out after a certain amount of use EG hard drives are often measured in thousands of hours of use before they are expected to fail, so it can seriously extend the life of your PC if you shut down your computer when it's not in use.
For these reasons it is highly recommended that you shut down your PC properly when not in use.
How is a TV controlled by a computer?
The traditional meaning of TV is that of an RF receiver (the "tuner") and a display unit. A Traditional TV set is a piece of analog technology; there is no digital component or computer interface. You cannot control one of these types of TV from your computer.
However, modern TV sets are specialized computers themselves, implementing some of the image control and user interface technology digitally. Many modern TV sets are already able to handle digital inputs both from an aerial (terrestrial digital TV) and from other sources, such as an HDMI input to connect a high-resolution DVD player or similar equipment.
Those TV sets might have a physical or logical interface to your computer. For example, the TV set itself might provide a small web server which you can use to connect your PC to the TV much like you visit any other web site. In case of a TV, you might be able to alter settings and view status information, for example.
More recent TV development often includes some form of "connectivity." Some units can access the Internet through wireless or wired LAN connections and display YouTube videos, for example. Others can display and play content from local DLNA servers, playing your digital music, photo or video collection from your home network.
There is no commonly accepted standard way of implementing "connected" TV sets, and all vendors try to gain a competitive advantage by supporting a few standard technologies (e.g. the HTTP and DLNA protocols) plus something of their own invention. Therefore, there is no single correct yet generic answer to this question, as the availability of PC-to-TV connectivity and its features is subject to the exact choice of TV model.
