RESEARCH METHODOLOGY http://en.wikipedia.org/wiki/Methodology Methodology  is the systematic, theoretical analysis of the methods applied to a field of study. It comprises the theoretical analysis of the body of methods and principles associated with a branch of knowledge. Typically, it encompasses concepts such as paradigm, theoretical model, phases and quantitative or qualitative techniques. A methodology does not set out to provide solutions - it is, therefore, not the same as a method. Instead, a methodology offers the theoretical underpinning for understanding which method, set of methods, or so-called “best practices” can be applied to specific case, for example, to calculating a specific result. It has been defined also as follows: "the  analysis  of the principles of methods, rules, and postulates employed by a discipline" "the systematic study of methods that are, can be, or have been applied within a discipline"; "the study or descrip...

Is 1 GB equal to 1024 MB or 1000 MB?

Image
A Byte is equal to 8 Bits. A Kilobyte is actually 1,024 Bytes depending on which definition is used. A Megabyte is approximately 1000 Kilobytes. A megabyte is a unit of information or computer storage equal to 1,048,576 bytes. A Gigabyte is approximately 1000 Megabytes. A gigabyte is a unit of information or computer storage meaning approximately 1.07 billion bytes. But 1 gigabyte = 1024 megabytes and this still be correct using the other acceptable standards. World bytes table: - 1 Bit = Binary Digit; - 8 Bits = 1 Byte; - 1000 Bytes = 1 Kilobyte; - 1000 Kilobytes = 1 Megabyte; - 1000 Megabytes = 1 Gigabyte; - 1000 Gigabytes = 1 Terabyte; - 1000 Terabytes = 1 Petabyte; - 1000 Petabytes = 1 Exabyte; - 1000 Exabytes = 1 Zettabyte; - 1000 Zettabyte = 1 Yottabyte; - 1000 Yottabyte = 1 Brontobyte. Traditionally, one gigabyte has been defined as 1023*3 bytes or 1,073,741,824 bytes or 2*30 bytes. This is the definition commonly used for computer memory and file...

Flash Memory and Flash Drive

Flash memory   is an  electronic  ( solid-state )  non-volatile   computer storage  medium that can be electrically erased and reprogrammed. Toshiba  developed flash memory from  EEPROM  (electrically erasable programmable read-only memory) in the early 1980s and introduced it to the market in 1984. The two main types of flash memory are named after the  NAND  and  NOR   logic gates . The individual flash memory cells exhibit internal characteristics similar to those of the corresponding gates. Where  EPROMs  had to be completely erased before being rewritten, NAND-type flash memory may be written and read in blocks (or pages) which are generally much smaller than the entire device. NOR-type flash allows a single  machine word  (byte) to be written – to an erased location – or read independently. The NAND type operates primarily in  memory cards ,  USB flash drives ,...
