Information T echnology FINAL E XAM N OTES All Software  Application Software- is a set of computer programs that helps a person carry out a task  System software -is to help the computer system monitor itself in order to function efficiently (an example of system software is a computer operating system or OS). Bitmap Graphics  A bitmap graphic is composed of a grid of tiny rectangular cells.  Each cell is a picture element, commonly called a pixel.  Each pixel is assigned a color, which is stored as a binary number.  With eight bits used to represent each color value, one pixel requires 24 bits. Vector Graphics  A vector graphic consists of a set of instructions for creating a picture  Vector graphics include standard shapes such as circles and rectangles  Vector graphics are used for line art, logos, simple illustrations, infographic elements, and diagrams created from scratch. Printers  An ink jet printer has a nozzle-like print head that sprays ink onto paper to form characters and graphics. Random Access Memory  RAM (random access memory) is a temporary holding area for data, application program instructions, and the operating system.  In RAM, microscopic electronic parts called capacitors hold the bits that represent data. Microprocessors  A microprocessor is an integrated circuit designed to process instructions.  It is the most important, and usually the most expensive, component of a digital device. Circuits and Chips • An integrated circuit (IC) is a set of microscopic electronic circuits etched onto a thin slide of semiconducting material. • The terms computer chip, microchip, and chip are commonly used to refer to integrated circuits. Read-Only Access Memory • ROM (read-only memory) is a type of memory circuitry that is housed in a single integrated circuit on the system board. • ROM contains a small set of instructions and data called the boot loader which tell a digital device how to start Torrents • BitTorrent is a file sharing protocol that distributes the role of a file server across a collection of dispersed computers. • A BitTorrent network server breaks a movie file into pieces and begins to download those pieces to the first computer that requested the movie. Communication Systems • A communication network (or communication system) links together devices to data and information can be shared among them. • A communication channel is the medium used to transport information from one network device to another. • Wired channels transport data through wires and cables Communication Protocol • In the context of networks, a communication protocol refers to a set of rules for efficiently transmitting data from one network node to another. • This process is called handshaking. • Networks use more than one protocol, and the collection of protocols for a network is referred to as a protocol stack. Packets • A packet is a parcel of data that is sent across a computer network; when packets reach their destination, they are reassembled into the original message according to their sequence numbers. • Communication networks use a technology called circuit switching, which establishes a private link between one telephone and another for the duration of a call. • A more efficient alterative to this process is packet switching technology, which divides a message into several packets that can be routed independently to their destination.
