INTERNET OF THINGS (IOT): interconnection of uniquely identifable embedded computing devices transferring data over network without requiring human-to-human or human-to-computer interactions. Things can be anything. Interconnectivity of IOT = we all become nodes, we generate data without knowing it = creating privacy + ethical issues. Network Software: Home networks require P2P network software. NETWORK OPERATING SYSTEM (NOS): useful for client/server network to handle information requests, Internet access, and use of peripherals by other network nodes. Wired Broadband Internet Connections: BROADBAND: type of high speed Internet connection w/ faster throughput. Data transfer speed between 1 to 500 Mbps. DIAL-UP INTERNET : Internet transmission w/ 56 Mbps. INTERNET SERVICE PROVIDERS (ISPs) : specialized providers. Common Wired Broadband Internet Connection Options: 1. CABLE: cable connections are shared so speed can drop during high-usage periods. Downloaded by remy hakim ([email protected]) lOMoARcPSD|4103943
2. DSL (DIGITAL SUBSCRIBER LINE): Speed drops as distance from the main signal source increases. Twisted-Pair cable splitting in three-lane highway: one for voice data, the two others for sending + receiving data. 3. FIBER-OPTIC SERVICE: transmits data via light signals, don’t degrade over long distances. Bundles of thin plastic or pure glass strands called OPTICAL CABLES, big amount of data transmitted very fast + converted to electrical pulses transmitting data signals to computer. SATELLITE BROADBAND: mostly used in rural/mountain areas where other connections are unavailable or costly. SATELLITE INTERNET: satellite dish connected w/ coaxial cable. Satellites connect w/ the company’s one by geosynchronous orbit far above earth. HOME SATELLITE <--------->OUTERSPACE SATELLITE<-------->COMPANY’S SATELLITE CABLE INTERNET: Broadband service transmitting data over coaxial cables. CABLE TV: One-way signal w/ programmed signals for television. Wireless Internet Access: MOBILE BROADBAND: Wireless options are also available such as cellular networks 3G or 4G LTE when Wi-Fi is unavailable. Wireless Internet access can easily be found anywhere. NET NEUTRALITY: All Internet data treated equally = types of user, content, communication mode, etc. = Internet open and free for everyone. MOBILE HOTSPOT: lets you connect more than one device to Internet but require access to a data plan (you can turn your phone into a hotspot cuz built-in Internet equipment). Dial-Up Connections: Dial-Up is the less costly way to access Internet (but 600 times slower than fber-optic), still available in some rural areas. When in use, telephone connection is tied up. Planning Your Home Network: Routers and Network devices need to be updated every few years to catch with technology improvement and speed of networks.
