Is there a way for 2 computers to be connected together?
They can be directly connected with the right rj connectors. Or just do it the easy way and buy a router, hub, or crossover and setup a simple network. Connect them by network id through the network wizard.
How many processors are installed on my computer?
This is becoming increasingly difficult, as a modern CPU chip now can contain several "cores" (each, and independent CPU), and each core may now possibly be able to run more than one process (a multi-threaded, or hyperthreaded core).
Virtually all desktop or laptop systems have 1 physical CPU. Only really high-end workstations will have more than 1 physical CPU. However, due to the concept of cores and threads, that one physical CPU can appear to be multiple Virtual CPUs to the operating system.
Honestly, the simplest way to find out more about your CPU is to reboot the system, and then watch the BIOS output. It should tell you what kind of CPU you have (almost always AMD or Intel something-or-other). If you don't see that information, hit "Delete" or "F1" or "F2" a couple of times right after the system starts - it will go into the BIOS setup, where you can see the CPU model.
After you've discovered what the CPU model number is, look up it's abilities on the web:
For AMD CPUs: http://products.amd.com/en-us/DesktopCPUResult.aspx
For Intel CPUs: http://ark.intel.com
There are ways to tell inside the OS, but it's a bit hard to describe, and highly dependent both on which OS (MacOS, Windows, Linux, etc.) and which version of that OS you are using.
How many pixels per inch is 600 dpi?
dpi means dots per inch. If you were to print a straight line one inch long using the max print setting (600 dpi for your printer) that line would consist of 600 dots. Fairly high quality image
The full meaning of FORTRAN in computer?
Usually thought to mean "Formula Translation", FORTRAN is a blend word name for a software language and compiler whose original full name was "The IBM Mathematical Formula Translating System". The first FORTRAN compiler was released in April of 1957. In 1991, however, the connection to the original meaning was dropped. So from the Fortran 90 of then to the upcoming Fortran 2008, the name is spelled with only the first letter capitalized.
How do you make a file on a PC?
Files may be a document or an image and they must be saved in a folder that you can create clicking on New Folder on Windows Explorer. Now you can drag it onto the folder that you have just created after named it.
What is the primary job that a computer performs?
1: Input
Whatever is put into a computer system.
2: Process
Manipulation a computer does to transform data into information
3. Storage
Temporary or primary storage is the computer circuitry that temporarily holds data waiting to be processed. Permanent or secondary storage is the area in the computer where data or information is held permanently.
4: Output
Anything that is output from the computer system, the results of processing.
5: Communication
Extension capability: Data maybe input from afar, processed in a remote area, stored in different locations, or output in other places.
What is the difference between the stack and the heap?
The stack is a local memory reserve where the program stores variable and function data. The heap is a special memory reserve where the programmer can dynamically allocate memory from. The heap is useful when the programmer doesn't know how large to make certain variables, he just constructs one of the right size during run-time.
How do you change FAT32 file system to NTFS file system?
1.you can go into my computer under the Removable Disk icon rightclick>format>then under the file system drop-down menu pick the file type (FAT,FAT32,NTFS) and then hit start at the bottom
2.If that don't work, then you might have accidentally deleted the partition, yes they do have them, you can simply stick a windows CD in while the flash drive is connected and reboot, the CD will run. go through its process until you come to the partition menu, the usb drive will be listed as a second drive, but ofcoarse smaller then your computers drive. (*WARNING* this will completely clear all data from the device or your hard drive so make sure you select the right one) Delete the existing partition then select C to create a new one. once your done creating a new partition press F3 and abort the rest, if you don't it will install windows. NOTE under the section saying file type, it will still say RAW when all is done.
reboot and then run threw my above method 1. to format the removable disk and when its complete you will be set as what ever type you choose from the drop-down menu.
This is what worked for me on several occasions however it always results in complete data loss. If anyone knows a better way please post, I would be extremely grateful.
What are the two major technologies that are used for hard drives in todays computers?
A hard disk drive (HDD) is a non-volatile, random access device for digital data. It features rotating rigid platters on a motor-driven spindle within a protective enclosure. Data is magnetically read from and written to the platter by read/write heads that float on a film of air above the platters.
Introduced by IBM in 1956, hard disk drives have fallen in cost and physical size over the years while dramatically increasing in capacity. Hard disk drives have been the dominant device for secondary storage of data in general purpose computers since the early 1960s, They have maintained this position because advances in their areal recording density have kept pace with the requirements for secondary storage. Today's HDDs operate on high-speed serial interfaces; i.e., serial ATA (SATA) or serial attached SCSI (SAS).
Which websites have free Christmas wallpaper for a desktop computer?
Free Christmas screensavers can be downloaded from Microsoft and Apple websites to be sure of getting malware free downloads. Alternatively they can be found on websites such as iTunes, but you should always check out the validity of the site before downloading as there are many sites that will also download viruses and trojans.

What does the computer networking term UDP stand for?
mmm Long Answer without getting too complicated
Think of TCP and UDP as doing more or less the same thing, the difference is the
Tcp is connection orientated : your computer sends 5 messages to another computer and the computer that receives the message sends your computer a message "ok i got those 5 messages, you can send me the next messages. If it does not get them it asks the sending computer to resend the messages it did not get.
UDP is connectioneles : your computer just sends all its messages and does not care if the computer at the other side receives them.
This does not means that they do not do any erroe checking is is just done on another level in something called (IT term coming up) the OSI MODEL.
hope i was not to technicall
What fees are associated with a data recovery service?
The price for any data recovery service depends on what is to be retrieved and the amount of the process to be done. Let say it will be a 3TB drive; normally any data recovery company charges $1 per GB so it will cost around an estimated $3000. But if it will be a simple or single file to be retrieved, then it won't be too much pricey. Still, it is up to the people you're going to hire or ask for help in recovering your files. Even an encrypted hard drive recovery can cost a different price.
Where can I find used vintage Apple computers online?
This online store can hook you up with a lot of different old computers, both Apple and not: http://oldcomputers.net/
Not very many places offer vintage Apple Computers. The best place to look would be ebay, they have a variety of vintage Apple products for sale.
What is more important when purchasing a computer?
What is most important in buying a laptop depends on the way you use your laptop. There is no single advice that fits all users.
If you are travelling a lot weight and power consumption are more important than when you laptop is standing on your desk at home most of the time.
Also, the applications you use on your laptop determine the amount of memory, the processor speed and the speed of your hard drive that is suitable for you.
Below are some of the things you should generally pay attention to when buying a laptop.
Weight and power consumption
If you travel a lot you probably want a smaller (12, 13, 14, 15 inch), lighter laptop that doesn't consume too much power and that doesn't need a big adapter.
Performance (processor and ram)
The processor (cpu) and the amount of memory (ram) determine how well your laptops performs. A power user that runs a lot of programs at the same time should be looking for a laptop with a fast processor and sufficient RAM, while someone that uses his or her laptop for occasional emailing and web surfing might be just as happy with a less powerful processor and less RAM. In current (2012) laptop 2 gigabytes of RAM is "ok", 4 is "average" and 8 is "nice".
Solid State Drives or regular hard drive?
Solid State Drives have entered the market about 10 years ago, but they have only recently become cheap and reliable enough to be really worthwhile. SSDs still cost more than a normal, magnetic hard drive, but they are significantly faster and make working with your laptop a more pleasurable experience.
Screen quality and resolution
Screen quality is not so noticeable when you have only one laptop. When you have more than one laptop, you can see there are big quality differences between the displays of different laptops. The best you can do is have a look in the store (or try searching youtube) and compare the brightness and sharpness of different displays.
Build quality
Some laptops are better built than others. Brands that offer a lot for a small price can have a poorer build quality, like laptop screen hinges that become too loose after a couple of years.
Warranty and repair cost
This is often overlooked. If your laptop fails after one and a half years, what will happen? Do you have to send it of for repair yourself and wait for weeks for it to return or does the manufacturer has a replacement or repair service that will be on your doorstep the next morning at little or no cost? Don't underestimate the annoyance of having to wait weeks for your laptop to get repaired!
How does computer games keep you healthy?
computers can be a useful diagnostic tool, and can help people identify illness, and get information about what to do to cure it. it can also reduce strain on healthcare services, as less people have to visit doctors.
Is a firewall a program to prevent undesired network traffic from your computer?
A firewall blocks or allows certain programs from accessing the internet. It can also be allowed to only deliver content that was sent to explicitly to your IP address. That means if you didn't request a page it will ignore that page and not show you the "pop up" or whatever was being sent.
Yes.
"Rebooting" means to reload the Operating System from scratch. This happens every time you swithch you computer off and then restart it.
