A genetically modified organism (GMO), also known as a transgenic organism, is any organism whose genetic material has been altered using genetic engineering techniques (i.e. genetically engineered organism).enetically modified crops (GM crops, or biotech crops) are plants used in agriculture, the DNA of which has been modified using genetic engineering techniques. In most cases the aim is to introduce a new trait to the plant which does not occur naturally in the species.
A hard disk drive (sometimes abbreviated as Hard drive, HD, or HDD) is a non-volatile memory hardware device that permanently stores and retrieves information. There are many variations, but their sizes are generally 3.5 and 2.5 for desktop and laptop computers respectively.
They allow the user to input specific types of information to be stored in the computer's memory. Many drives are input-only, meaning they can only read information. Other drives, such as CD and DVD writers, can output information to physical media. The most common drive is a hard disk drive (HDD). This drive is usually located inside the computer and is accessed directly through its operating system. The HDD serves as a computer's main source of storage. Media files, documents, games and entire operating systems can be called up at will from the HDD.
