OSI Model
100
First standard model for network communications created in the 1980s to visualize and communicate how networks operate, and helps isolate and troubleshoot networking problem
What is Open Systems Interconnection Model (OSI model)
100
A degrading signal or signal loss can happen when a cable may be bent too much
What is attenuation?
100
What are the two types of Networks?
Wired and Wireless
100
Ethernet cables can be created with connections mounted at the end. What is the lab you did in class?
What is Crimping?
100
Transport Control Protocol (TCP) which is connection based and User Datagram Protocol which is connectionless occur at what layer?
What is Transport Layer, Layer 4
200
Double Jeapardy!! Where the MAC address and Switch is Located
What is the Data Link Layer, Layer 2
200
Founded in 1963, this organization continues to create internet and network standards
What is IEEE, Institute of Electrical and Electronics Engineers
200
All of the computers and devices in Riverside Preparatory Academy located in one location are considered what type of Network?
What is a Local Area Network (LAN)
200
Device that creates a wireless local area network, or WLAN, usually in an office or large building. An access point connects to a wired router, switch, or hub via an Ethernet cable, and projects a WiFi signal to a designated area
What is an Access Point
200
The number 192.168.210.14 is used for identification and location of a device on a network. What is this number called?
What is an IP address?
300
Responsible for the physical cable or wireless connection between network nodes. Where hubs and cables are.
What is Physical Layer, Layer 1
300
Double Jeapardy!!! This cable is made from glass, uses light signals, more expensive, used for longer distances, and no outside interference
What is Fiber Optic Cable?
300
A system that connects two or more computing devices for transmitting and sharing information
What is a Network
300
This device connects computers to network via wired and wirelessly.
What is a Network Interface Card (NIC)
300
The serial number 00-B7-D0-63-C1-86 on the Network Interface Card is what?
What is the MAC address
400
Used by end-user software such as web browsers and email clients. It provides protocols that allow software to send and receive information and present meaningful data to users.
What is Application Layer, Layer 7
400
802.11 is what standard?
Wifi
400
The bank headquarters located in Texas with branch offices located in other states
What is a Wide Area Network (WAN)
400
A device that connects two or more packet-switched networks or subnetworks. It serves two primary functions: managing traffic between these networks by forwarding data packets to their intended IP addresses, and allowing multiple devices to use the same Internet connection
What is a Router
400
Creates communication channels, called sessions, between devices. It is responsible for opening sessions, ensuring they remain open and functional while data is being transferred, and closing them when communication ends.
What is Session Layer, Layer 5
500
Also known as "the heart of the OSI model", is where the delivery of data takes place
What is the Transport Layer, layer 4
500
This type of cable is cheaper, used for short distances, uses electrical signals, and affected by interference
What is Copper Cable?
500
A network at home, consisting of only a few nodes
What is a Small Office Home Office (SOHO) network
500
Connects devices within a network (often a local area network, or LAN) and forwards data packets to and from those devices using a MAC address
What is a Switch
500
Handles IP addressing, routing, and packet forwarding
What is the Network Layer?
