Data are numbers (GPA), information (Name), knowledge (understanding). Generation Z; you. Y Generation most ppl in the workforce; bbyboomer.

The Data World: Data Driven Business Transaction processing: information that is divided into different operations. Relational database principles these related tables can be joined when they contain common columns. The uniqueness of the primary key tells the DBMS which records are joined with others in related tables. This feature allows users great flexibility in the variety of queries they can make. Data Hierarchy: bit>byte>field>record>file. Entity is a person, place, thing, or event.

Internet Protocol (IP) is responsible for disassembling, delivering, and reassembling the data during transmission; important because it connects computers. The transmission technology that breaks up blocks of text into packets is called packet switching. Each packet (data transmitted over the internet, small) carries sender's IP address, the intended receiver's IP address, the number of packets in the message, and the number of the particular packet within the message. When the packets reach their destination, they are reassembled into the original message. Why do organizations use packet switching? The main reason is to achieve reliable end- to-end message transmission over sometimes unreliable networks that may have transient (short-acting) or persistent (long-acting) faults. Benefits of 3G/4G – 3G uses digital signals and can transmit voice and data up to 384 Kbps when the device is moving at a walking pace, 128 Kbps when it is moving in a car, and up to 2 Mbps when it is in a fixed location. 3G supports video, Web browsing, and instant messaging. A 4G provide a secure all-IP (Internet Protocol)-based mobile broadband system to all types of mobile devices. Client/server computing form of distributed processing in which some machines (servers) perform computing functions for end-user PCs (clients).links two or more computers in an arrangement in which some machines, called servers, provide computing services for user PCs, called clients. The client requests applications, data, or processing from the server, which acts on these requests by “serving” the desired commodity. Near-field communication form contactless communication b/w devices like phones. Bluetooth; personal. Infrared; lights .Broadband is the transmission capacity of a communications medium faster than 4 Mbps downstream and 1 Mbps upstream. Internet providers : DSL -
