Document Summary
Size of file *multiply bytes by 8 to get bits. Computer network system connecting computers and other devices via communication media. Broadband transmission capacity of communication mediums faster than 4 mbps. File server/network server software and data for the network. Analog signals continuous waves that transfer information by altering characteristics of waves. Digital signals discrete pulses representing series of bits. Modem converts digital signals to analog signals using modulation. Wireline/cable media physical wires to transmit information. Twisted pair wire most prevalent business phone, inexpensive. Hypertext transfer protocol (http) defines how messages are formatted and interpreted by receivers. Distributed processing divides processing among 2+ computers. Client/server computing links 2+ computers, one as server and one as client. Peer to peer processing (p2p) client/server, all computers are both (ex. Internet backbone primary network connections and communication lines, fiber-optic network. Intranet uses internet protocols so users can take advantage of familiar apps and work habits.
