Network Components and Types
Name three Host Devices.
Pc, Laptops, Servers, Tablet, Smartphones, Printers, Webcam, IP phones, Scanners, etc...
Which connection type sends voice calls and network data over the phone lines (at different frequencies)?
DSL- Digital Subscriber Line
Name the protocol:
Reliable, acknowledges data received, Resends lost data, delivers data packets in order.
TCP- Transmission Control Protocol
What wireless protocol (WiFi standard) should be used in new applications?
802.11ac
Name the Type of Server: The service used by ISPs, network administrators, and wireless routers to automatically assign IP addressing information to hosts
Dynamic Host Configuration Protocol (DHCP)
Name three Intermediary Devices?
Name the internet connection that uses coaxial cable lines to send network data over TV lines?
Cable
Name the protocol:
Fast, Low overhead, doesn't require confirmation of delivery, does not resend lost data, delivers data on arrival.
UDP- User Datagram Protocol
What wireless communication protocol is used most commonly in a PAN?
How many devices can this protocol support at one time?
Bluetooth & 7
Name the Server: the method computers use to translate domain names into IP addresses.
DNS- Domain Name Service
Identify the network type acronym.
PAN, LAN, VLAN, WLAN.
PAN- Personal Area Network.
LAN- Local Area Network
VLAN-Virtual Local Area Network
WLAN- Wireless LAN
Name the "backbone" network medium that uses Light to transmit data at a higher bandwidth?
Fiber Optic
T/F: an application has to be either TCP or UTP, never both.
False: Many applications actually use both.
Ex. HTTPS and DNS are examples that use both.
RFID- Radio Frequency Identification comes in two varieties. Active and passive. what are the maximum Ranges? (in meters)
25m and 100m
Trivia: the NFL uses RFID to track player movement, speed, and direction in game.
Name the server: these Servers have the authority to act as another computer. Commonly used as to cache web pages that are frequently accessed by devices on the internal network..... also Crime
Proxy Servers
Identify the network type acronym.
WMN, MAN, WAN, VPN.
WMN- Wireless Mesh Network
MAN- Metropolitan Area Network
WAN- Wide Area Network
VPN- Virtual Private Network
an always-on service that uses radio signals for transmitting internet access. Radio signals are sent from a tower to the receiver that the customer connects to a computer or network device.
Line of Sight
T/F: the application/source ports used in transport layer protocols to send data to the correct applications are physical ports inside the computer hardware.
False: Source ports are "dynamically" generated (basically random) numbers created by the sending device to identify the "tab" that should receive the data from the server. Application ports are "well-known" because they stay consistent over much of the web. Examples: HTTP uses port 80, and HTTPS uses port 443
Name a common use of NFC-Near Field Communication
Apple pay
Samsung payment
Etc...
Name the server: a store-and-forward method of sending, storing, and retrieving electronic messages across a network. Requires the use of several application types.
Email Servers require these applications to run: Simple Mail Transfer Protocol (SMTP), Post Office Protocol (POP), and Internet Message Access Protocol (IMAP).
Which type of network allows users to securely connect to a network over an unsecured network?
VPN- Virtual Private Network
A Space-Based networking technology that makes use of a "dish" attached to a person home to receive signals from the internet provider.
Satellite
DNS- Domain Name Services uses which port number? What Transport layer protocol(s) does it use?
Which of the two "smart home" technologies discussed uses a device called a "coordinator" to create and maintain its network? (Zigbee or Z-wave)
Zigbee
Name the server type: ___ protocol allows networking devices to send their system messages across the network to _____ servers.
Syslog
