For most, that can print digital images offers a practical way to store and show pictures when you have a computer around. In addition, no longer have to worry about as they can spoil an entire roll of film. However, things are not so simple. There are several issues you should think before you print digital photos, that was not wasted paper and toner then. In this article we will present some basic terms related to digital photography and we'll offer some tips for printing images
 
Resolution
Resolution refers to the clarity (the sharp) image and is usually measured in dots per inch''''- how many points are included in a square with sides of 1 inch (2.54 cm). The same term also refers to the clarity of the image that displays or monitors that reprosuc printers. Depending on your needs, documents can be scanned at different resolutions. As the resolution is higher, with both electronic image quality will be better (thus more clear), and graphic file size will be higher.
  Turning to digital photography, the first thing that you must ensure is that your computer full resolution image. If the final image will have only a resolution of 72 dpi, no sense even to try to print, such a resolution is good for viewing the photo display on the monitor. If you want to print digital images, their resolution should be 200-300 dpi (for format 20x25 cm).
 
Pixel
Time is short for picture element''''and refers to the smallest part of a digital image. Each image is composed of thousands or millions of such pixels. Pixel is a unit basis, if you will, behind the formation of any video or digital, is actually a point of a certain color and brightness. As an image has more pixels, so the resolution will be higher. 1 megapixel is 1 million pixels.
 
JPEG
Represent the initials for Joint Photographic Experts Group, a group that designed this format compressed image. The format is characterized by loss of image quality, to remove information that you do not consider necessary. JPEG files are also several ways, some are compressed more, others less. The format is most often used, but when it comes to printing, it becomes less interesting because of the loss of information.
 
Resolution and print quality
As the number of megapixels the camera is digital fotograiat larger image will even be more, and hence the photo quality will be better when printed or enlarged.
 
1-2 megapixels - digital cameras that have this resolution are appropriate only to achieve images that will be sent in electronic format via email, for example, but are not good for those who want to print their pictures on paper. Now, most of the rooms built in camera mobile phones or cameras to the computers have 1-2 megapixels.
3-4 megapixels - digital cameras with resolutions produce good images, which can be printed on an approximately 10x15 cm.
5-6 megapixels - digital images made with rooms that have such a resolution can be printed on 20x25 cm format.
7 megapixels or more - with these resolutions cameras produce images that can be enlarged and printed on a format of at least 25x35 cm.

How many megapixels do we need for the most common formats:
4 megapixels - A5-A4
5 megapixels - A4
6 megapixels - A3-A4
8 megapixels - A3
12 megapixels - and over A3
 
It is really easy to you immediately if the image quality is required, only seeing the file size. An image of only 100 kb or less is definitely too low a resolution to be printed on good quality. Size of at least 400 kb is a good indication that the image resolution that contains the file format is suitable for 20x25 cm.
 
Paper
If you want the image to get in really high quality standards, especially if you want photos to take more time, then you will need to buy special paper for printing digital photos. Finally, the images are printed impression and good on paper because they are printed.
 
There are many types of matte or glossy paper that can be used for this purpose and, except for their quality, you must think and type recommended for your printer are special paper for the printers jet of ink, which takes more and are not manufactured on the basis of acids they are not cheap - in general this special paper costs more - so we need to think well of what you need. Print the picture only after you are sure it is included as well, as did the last changes and touch-ups, etc..
 
In ordinary printers ink jet and laser printing are very good documents that contain text and / or tables / graphics, but they are not always suitable for printing digital photos at a high quality.
 
For the most common photo formats:
9x13 - 540x780 px
10x15 - 600x900 px
13x18 - 7801080 px
15x21 - 900x1260 px
20x30 - 1200x1800 px
30x45 - 1800x2700 px

The most obvious way that moisture penetrates the house is using the rain that may fall on a roof with small cracks or go near the windows are not sealed well. It is therefore very important to fix immediately and the smallest fissure.

Moisture is also generated when cooking, make the shower, wet the plants, wash or even when breathing. More than 99% of water used for plant drench get in the air. For example, breathing and perspiring just a normal family adds about 11 liters of water daily indoor air.

Because air always contains moisture, any air movement and moisture brings with him. You know that if the air passes through the plugs or switches or electrical equipment and reach the walls, and moisture follow the same path.

The same is true for su air movement through any cracks between the house and bridge, garage or basement. Even very small cracks around pipes can bring large amounts of moisture because the air flow in pipelines is higher than others in the house.

Moisture and spread using a different process called diffusion. Diffusion takes place when a certain part of your house has a higher level of moisture than the other, like the movement of moisture in the bathroom bedroom after a shower with hot water that filled a steam bath.

Diffusion takes place and if not occurring air movements. As the heat passes from a warm space in a cool, even if you must pass through a wall, water vapor will move from a place with a concentration of greater moisture in a space that has a lower concentration even if you must pass through a wall.

Moisture can enter your house during construction. Construction materials can irrigate during construction of the rain, or from roua Lying on the ground moist. Try to avoid moisture as possible because it can bring great damage your house.

20 years ago, processors are based on semiconductors memory went to the same frequency with memories.
In the meantime, has moved to EEPROM's, Edo Ram, SD Ram, DD Ram, DDR2, DDR3, DDR4, DDR5 memory and has left behind more processor speed.
Why?
Memory was very expensive 20 years ago, of being more valuable than 1,000 times its weight in gold
It steals from the memory banks to sell for
Meanwhile, the price has decreased to 1 c / MB, while the price remained cache 20 $ / MB, ie 1000 times more expensive
Why?
For it's non-economic to produce memory with very high frequencies, 4 GB would cost around $ 80,000, it cost $ 200.
But how to calibrate the processor speed of memory?
There was a processor needs only the memory that it uses when you execute the instructions (not counting the speed of 10,000 times greater than the virtual memory on disk), which does not exceed a few KB (instructions for that are short).
That was the idea of installing a fast memory called a buffer or cache, directly on the processor, to take instructions from main memory and to hold them until the processor executes, and then to give further results, passing him back in RAM.
This memory is called Level 1 cache and is divided into 2 equal parts: one part data and part of instruction, both parties hold 32 KB each in a dual-core Intel.
AMD is on the other hand, processors are "short and fat", so he opted for a cache level 1 to 2 times higher: 128 kb / kernel.
Is needed and a shared memory of nuclei in which you hold the instructions for pre-emptive multitasking (which probably will be done) so he appeared cache level 2.
At first it was mounted directly on the motherboard, then the processor
Its size ranged between 1 and 4 MB; recent new Penryn processors have 6 MB L2 cache, while the Nehalem prepare for 30 MB.
Server processors such as Intel Itanium2 9050, 12 million have already 24 MB L3 cache
Level 3 is used only for servers for you to pass the data server clients
But why there are differences between the processor and cache is the impact on performance?
Processors with the Core architecture require 2.2 MB L2 Cache at a frequency of 2660 Mhz.
Since the cache is produced lithographs and pills directly on wafer, can not put 2.2 Mb, but only 2 MB or 4 MB.
So processors "good" E6xxx have 4 MB cache, and the "budget" E4xxx only 2 MB cache.
And also the low frequency E6xxx all have 2 MB cache.
But the performance difference is only 5% on the same frequency of operation.

It is important to know that the cache required varies directly proportional to the frequency of operation.
So to overclock a 100% on a E4xxx, it takes 4 MB cache.
Entry level E2xxxx processors or Celeron 1xxx suffered from massive lack of cache memory, performance is reduced by up to 30%.
This lack may be compensated by overclock to 200 Mhz and 500 Mhz 2xxx to 1xxx.

Need to realize that you wrote here microseconds in the case of transfer of the core and caches (cache transfer rates with hundreds or thousands of GB / sec) and milliseconds in case of transfer in RAM Cache
Talking seconds when not already have enough RAM and disk use.
