regarding a Wi-Fi's service set identifier (SSID)
An SSID is the Wi-FI's name. Most routers transmit the SSID every few seconds so roaming devices can find the signal. In home networks, after all legitimate devices have connected to SSID once, transmitting the SSID is unnecessary.
The amount of data that a transmission media can carry in a given amount of time is called the media's
Bandwidth
The capacity of a particular transmission medium is called its
Bandwidth
An internet connection that has enough bandwidth to allow multiple computers to be connected to the same router is called a __________ connection
Broadband
Has the most bandwidth
CAT 7 cable
Charateristics of microwaves
Capable of transmitting internet signals over long distances Used to transmit internet signals to and from satellites Used to transmit internet signals where wires may be impractical Line-of-sight transmission -- signals must not be physically interfered with
The fastest growing internet service provider media is

Charateristics of a router
Connects networks Provides hardware firewall protection Usually incorporates switches
Often IP addresses are structured and assigned by a service called a _______ or by a network administrator
DHCP
A wireless router that transmits WiFi signals on two separate frequencies is a _______
Dual-band router
Most commonly used within a network and is sold by category e.g. CAT-7

The ________ portion of an IP address is indicated by the remaining bits that are present after the network identified and identify the host of the network
Host
An IP address is determined by the network on which it is
Hosted/assigned
A public WiFi site is referred to as a
Hotspot
remote access
IT professionals spend a lot of time protecting networks from unauthorized connections from outside into a LAN. However, there are times when it is necessary to allow outside connections to a LAN. This is referred to as
1. connect incoming DSL line to modem 2. plug in and turn on the modem 3. connect router to the modem 4. plug in and turn on router 5. turn on computer and log onto your new wifi signal 6. navigate to the router manufacture's website to set up router and network for peak efficiency and security
If you receive both a modem and a wireless router from your ISP, place the following steps in the correct order if you wished to setup a Wi-Fi network.
statements are true regarding troubleshooting network hardware issues
If your network is not working it is a good idea to check the status of the indicator lights. Sometimes firmware updates can occur that can cause a network outage. If you experience trouble you may need to reboot the hardware device. A device that is not positioned properly can cause weak signals and system issues.
IP stands for __________ ___________ and is also called
Internet protocol; network identifier
WANs
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 or Wide Area Network is created. The largest WAN on earth is the Internet.
Identifies a device within a network
MAC address
Characteristics of fiber-optic lines
Made of one or thousands of fibers High-speed transmission Thin light-carrying glass wire/fiber Minimal electromagnetic interference Useful for long-distance connection, even under the ocean
true
Many 4G and 5G cellular Internet Service Providers offer a device that serves as a hotspot for your home and includes an integrated modem and router
Broadband is usually measured in

MAC stands for
Media Access Control
Radiowabes that transmit internet signals to and from satellites in space are called
Microwaves
Device in a network that converts analog (wave) signals into binary (digital) signals and and vice-versa is a modem
Modem/modulator-demodulator
Modem stands for
Modulator-Demodulator
Traits of wifi

Authentication
Remote access connections must be secured using authentication and encryption software. ______ software confirms the identity of the user or computer system
The device in a network that keeps track of connected devices' MAC addresses, allows several computers to use your home network with just one internet connection, and is usually incorporated in a router is the
Switch
Also ccx called twisted pair wire
Telephone wire
WEP
The original protocol (standard) for Wi-Fi security that was widely introduced in 1999 but replaced in 2003 was known as
