ITEC 1001- Networking and Immersive Technology
Facts about packet switching
All packets are routed through a network based on the associated address information; the internet uses packet switching to transfer data and information between hosts; addressing information and data are included in each packet
Because it locates cellular devices, assigns frequencies, transmits signals to the correct sites, the ___ is probably the most important part of any cellular network.
Base transmission station
What three items are required to set up a home Wi-Fi network?
Modem, router, internet signal
A popular peer-to-peer sharing protocol that allows users to share software, movies, and other files is
BitTorrent
Which of the following is an advantage of using a cellular network instead of a Wi-Fi network when connecting a smartphone to the internet?
Cellular networks are accessible from more places
Internet transmission media
Coaxial (TV) cable, Wi-Fi radio waves, telephone wire
Characteristics of a base transceiver station
Connected to a cell tower; broadcasts weak microwave signals to create "cells" of mobile coverage; sends phone signals to the cellular provider's Mobile Switching Station
Switch
Connects devices within a network
Router
Connects two or more networks
Modem
Converts digital signals to analogue signals and vice versa
Often IP addresses are structured and assigned by a service called a - or by a network administer
DHCP (Dynamic Host Configuration Protocol)
What technology allows for the electronic communication of business-oriented transactions and information between people and organizations?
EDI, Electric Data Interchange
In the U.S. the federal - covers most consumer oriented electronic transactions
EFT Act
Facts about switches
Ensure correct data is transferred to and from the correct computers in networks; connect computers and other devices within a network; usually integrated in the routers of home networks
The - - Protocol (FTP) is used for transmitting large files from one server to another over the internet
File transfer
True facts about WANs (Wide Area Networks)
Large organizations with many offices located across the globe often have individual LANs in each location that need to be connected in order to share data and information; when two or more LANs have been connected using a public network a WAN is created; the largest one on earth is the internet
A switch distinguishes between various devices within a network by their - addresses
MAC
Modems change signals from analog waves (modulated) to digital (demodulated) signals, thus, modem stands for
Modulator-Demodulator
Advantages of having a 3G phone
More energy efficient- battery lasts longer; less expensive
Local Area Networks (LANs)
Network of computers connected in a small geographic area such as an office or college campus
IP addresses are assigned by the Internet Corporation for Assigned Names and - (ICANN)
Numbers
A signal transmitted every few seconds by a wireless router so that a user's computers can identify the Wi-Fi hotspot is called an
SSID (Service Set Identifier)
Facts about client/server networks
Server-based networks are designed to have individual computers and devices connected to the network interact through a central server computer; in this type of network when a client requests information or access to the internet the request is controlled by the server; server-based models are popular because they provide more security than a peer-to-peer network
Facts about how IP addresses are determined
Structured and assigned by a Dynamic Host Configuration Protocol; all hosts on the same network share the same established network address, but are assigned a unique host number; an IP address is determined by the network on which it is hosted
Mobile - Stations (MSS) identify your phone's signal so that you can receive calls
Switching
"Because it is my name! Because I cannot have another in my life!"
The Crucible, Arthur Miller
Steps that occur after you press send on your phone
The receiver's MSS locates the receiver's phone and sends a signal to the receiver's BTS and associated cell tower, the cell tower's base transceiver station sends the signal to your MSS, the signal is sent via weak microwaves to a cell tower, your MSS sends the signal to the receiver's MSS
WPA2 stands for

Facts about Virtual Private Networks (VPNs)
Allow for encrypted data communications using the internet as a pathway for data transmission and communication; creates a secure connection between two computers; people within the organization use VPN software to login to the VPN
The volume of data that can be carried on an Internet transmission media in an amount of time is called -.
Bandwidth (larger bandwidth= more data per second)
