Advice 2: What is reader and what is it for
Why you need a card reader?
Card reader is multiperiodic designed to read data from memory cards. Memory cards used in mobile phones, cameras, PDAs and other devices. Immediately the question arises, why do we need this reader if you can read the information and using the USB cord that is standard on all devices. But the readers has its advantages.
When transferring data using a card reader the read speed information will be at least 6 MB/s data transfer using USB cable usually comes with a speed of 300 KB/s. That is, the speed of reading the files through the card reader 20 times more than via cable.
The second advantage is the convenience and practicality of the reader. Typically, when connecting different devices via USB cable need to install drivers or additional programs that the computer could identify them. It's not always convenient, especially if you have more than one computers and many digital devices. When you connect the reader with no such problems, and inserted memory cards appear as separate removable drives.
Moreover, the connection of any device (e.g. phone or camera) via USB cord has a negative impact on the battery and reduces its lifespan. When using a card reader the problem does not exist, as in this case, you use only the memory card device.
Choosing the reader, you also need to pay attention to the number of supported types of memory. The more different memory cards can support the device, the lower the data transmission speed and higher price. Therefore, to choose readers wisely.
What are the readers?
Depending on the connection method, the readers are divided into 2 groups: external and internal. Internal card reader will be useful to PC users because it is inserted inside the system unit in place, which is given to the drive. Also, it is called a built-in card reader. Since wearing such a device will be problematic (you need to constantly connect and disconnect it inside the system unit) using internal CardReader better on your home computer.
Popular now considered as external card readers. This device is more compact and connects to your computer (or laptop) via a USB cable. In size it is comparable to a normal USB flash drive that allows you to carry it even in your pocket.
Advice 3: How to choose a card reader for your computer
The card reader is a device that allows you to read data from memory cards. If you ever already use a reader, have you noticed that when connected through card reader the memory card visible just like a regular flash drive and no special software to work with it is not necessary. But not sold one kind of memory card, so the choice of reader must be approached carefully.
What types of scanners you can find in the sale?
First, the readers can be divided into internal (installed in the computer case connect to the motherboard) and external (connect cord to the USB port of the computer like keyboard, mouse).
Second, the readers can be divided according to the types of cards they support. You can find card readers for each type of memory card, but there are universal devices that allow you to work with multiple types of cards. If you are sure that you need only one card type for all your devices, you can buy a card reader just for them (most often, this card reader looks like a USB flash drive with the connector in order to insert memory card), but the universal reader will not spend money if there is a need to read data from the card of a different type.
Tip: types of cards supported by the reader, this is its main characteristic. Before buying a card reader, inspect all devices in which you use a memory card, record the type and in the store ask the seller to show you all the readers who supported the work with all your maps.
The operating system compatibility is also important. Before you pay money, please note that the box (or in the passport of the device), you have included all of the OS, which the software of the scanner can work.
And of course, I must say that it is possible to find readers a funny shape. Choose a reader as a gift to yourself or friends – such a useful toy at an affordable price will make the computer not only easier but also more fun.
