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...

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 ,...

Computer Graphics?

Image
Computer graphics Computer graphics  are  pictures  and  movies  created using  computers  - usually referring to  image  data created by a computer specifically with help from specialized graphic hardware and software. It is a subset of  computer science  and a recent field. The phrase was coined by computer graphics researcher  William Fetter  of  Boeing  in 1960. Another name for the field is  computer-generated imagery , or simply  CGI . Important topics in computer graphics include  sprite graphics ,  vector graphics ,  3D modeling ,  shaders ,  GPU  design, and  computer vision , among others. The overall methodology depends heavily on the underlying sciences of  geometry ,  optics , and  physics . Computer graphics is responsible for displaying art and image data effectively and beautifully to the user, and processing image data received ...
