A Flash memory is a type of hard device which is used to save information. Is a small thing like a pen .It saves a lot of information ,for example ,pic,music and videos .There are many kinds of flash memory such as Sony ,Toshipa and LG.
It can be used with any computer that has USB .People use it anywhere like home ,work or school .It is easy to use ,and doesn't need batteries .When it is plugged in a computer, it is ready and doesn't need any installation but we need to be careful with because it can carry viruses from a computer to another .
For me, my flash device is more important than my books and my tools .I need it everywhere to carry my important files and document with me where i go .
