DVD playerA DVD player is a machine that plays DVDs produced under both the DVD-Video and DVD-Audio technical standards, two different and incompatible standards. Many DVD players will also play audio CDs. DVD players are connected to a television to watch the DVD content, which could be a movie, a recorded TV show, or other content.
Optical discAn optical disc is a flat, usually disc-shaped object that stores information in the form of physical variations on its surface that can be read with a beam of light. Optical discs can be reflective, where the light source and detector are on the same side of the disc, or transmissive, where light shines through the disc to be detected on the other side. They may contain analog or digital information, or a mixture of the two.
GigabyteThe gigabyte () is a multiple of the unit byte for digital information. The prefixgiga- means 10 in the International System of Units (SI). Therefore, one gigabyte is one billion bytes. The unit symbol for the gigabyte is GB. This definition is used in all contexts of science (especially data science), engineering, business, and many areas of computing, including storage capacities of hard drives, solid-state drives, and tapes, as well as data transmission speeds.
Compact discThe compact disc (CD) is a digitaloptical discdata storage format co-developed by Philips and Sony to store and play digital audio recordings. It employs the Compact Disc Digital Audio (CD-DA) standard and is capable of holding uncompressed stereo audio. First released in Japan in October 1982, the CD was the second optical disc format to reach the market, following the larger LaserDisc (LD).
Digital mediaIn mass communication, digital media is any communication media that operates in conjunction with various encoded machine-readable data formats. Digital content can be created, viewed, distributed, modified, listened to, and preserved on a digital electronic device, including digital data storage media (in contrast to analog electronic media) and digital broadcasting.Data storageData storage is the recording (storing) of information (data) in a storage medium. Handwriting, phonographic recording, magnetic tape, and optical discs are all examples of storage media. Biological molecules such as RNA and DNA are considered by some as data storage. Recording may be accomplished with virtually any form of energy. Electronic data storage requires electrical power to store and retrieve data.
DVD recordableDVD recordable and DVD rewritable are a collection of optical disc formats that can be written to by a DVD recorder and by computers using a DVD writer. The "recordable" discs are write-once read-many (WORM) media, whereas "rewritable" discs are able to be erased and rewritten. Data is written ("burned") to the disc by a laser, rather than the data being "pressed" onto the disc during manufacture, like a DVD-ROM.
Digital dataDigital data or digital information, in information theory and information systems, is data or information represented as a string of discrete symbols, each of which can take on one of only a finite number of values from some alphabet, such as letters or digits. An example is a text document, which consists of a string of alphanumeric characters.
Injection molding machineAn injection molding machine (spelled injection moulding machine in British English), or injection press, is a machine for manufacturing plastic products by the injection molding process. It consists of four main subsystems: the injection unit, the clamping unit, the drive unit, and control systems. OperationInjection molding machine molds can be fastened in either a horizontal or vertical position.
JapanJapan is an island country in East Asia. Located in the Pacific Ocean off the northeast coast of the Asian mainland, it is bordered to the west by the Sea of Japan, the Sea of Okhotsk in the north, and the East China Sea in the south. The Japanese archipelago consists of four major islands alongside over 14,000 smaller islands.*As an Amazon Associate I earn from qualifying purchases.
