Network Protocols & Models
This characteristic of data transfer refers to the time, including delays, for data to travel from one given point to another.
What is Latency
When data is transmitted across metal wires within cables, it is encoded into these patterns.
What are electrical impulses.
This term, abbreviated from "binary digit," represents the smallest piece of data, having only one of two possible values: 0 or 1.
What is a bit.
This Cisco IOS CLI mode is often referred to as "view-only" mode and has a prompt ending in the ">" symbol
What is user exec mode
This is the case-sensitive, alphanumeric string that is essentially the name of the wireless network and must be the same for all devices connecting to a specific WLAN
What is SSID (Service Set Identifier)
This process, conceptually similar to placing a letter inside an envelope, involves adding a header containing addressing information to data to ensure it is delivered across the network
What is Encapsulation
This is the physical medium used by cable television service providers, featuring a single rigid copper core, often employed by ISPs
What is Coaxial cable
This term refers to the theoretical maximum number of bits that can be sent through a medium per second, typically measured in Mbps or Gbps
What is Bandwidth
When command output exceeds the display space, the IOS shows this prompt, and pressing the Space bar displays the next full screen
What is the --More-- prompt
To conserve battery power, mobile devices are preprogrammed to use this type of network first, whenever one is available, before connecting to a cellular data network Answer: This low-power, short-range wireless communication technology enables data exchange for devices that are in very close proximity to each other, usually less than a few centimeters
What is NFC (Near Field Communication)
In human or computer communication, these are the rules that must be followed for a message to be successfully delivered and understood
What are Protocols
This type of cable is made up of four pairs of wires twisted together to reduce electrical interference and is the most common wiring used in a LAN, such as Category 5e.
What are Twisted-Pair Cables
This 8-bit group, which can be converted into its decimal value, is one of the four groups that make up a 32-bit IPv4 address
What is an Octet
This capability allows users to shorten commands and keywords to the minimum number of characters necessary to uniquely identify the command
What is command abbreviation
This low-power, shorter-range wireless technology is intended to replace wired connectivity for accessories such as speakers and headphones, and it allows multiple devices to communicate over short distances
What is Bluetooth
This network model, composed of the Application, Transport, Internet, and Network Access layers, is also known as the Internet Model.
What is TCP/IP model
Because it transmits data using light instead of electricity, this medium is not affected by electrical interference and has a very high bandwidth
What is Fiber-Optic cable
This numbering system, which uses the digits 0–9 and the letters A–F, is used to represent IPv6 and Ethernet MAC addresses
What is a hexadecimal
This Cisco IOS command is used to display and verify the Layer 3 information and status for a specific interface on a network device
What is "Show IP Interface"
To protect Wi-Fi communications on mobile devices, security precautions recommend enabling this type of connection when sending sensitive data and generally using WPA2 or higher encryption on home networks
What is VPN (Virtual Private Network)
Used for data network design and troubleshooting, this seven-layer structure describes the functions that must be completed at each layer but does not specify precisely how a function should be implemented
What is OSI model
The maximum distance a signal can successfully travel, the installation environment, the required data speed, and cost are the four main criteria for choosing this network element
What is Network Media
This address is 128 bits in length and is represented using 32 hexadecimal values, often written in eight 16-bit groups referred to as hextets.
What is IPv6
This commands ends any configuration mode and returns the user to privileged EXEC mode
What is "Exit"
An IPv4 address is composed of two parts: the network portion, which locates the unique host address, and this portion, which uniquely identifies the device within that network
What is the host portion
