Networking Fundamentals
This seven-layer framework that defines the functions of a telecommunication or computing system, with each layer representing a specific set of tasks or functions. Also sequentially list out the layers starting at layer 1.
What is the OSI Model
Physical, Data link, Network, Transport, Session, Presentation, and Application Layer
Please do not touch Sean's pet alligator
All people seem to need data processing
This is the term for a pre-configured pathway used in routing tables, where the network administrator manually defines the route, specifying the destination network and next-hop address, providing a fixed path for data to follow.
What is a Static Route
This IEEE standard, often used for wireless networking in the 2.4 GHz frequency range, supports data rates up to 11 Mbps
What is 802.11b
This a process that involves systematic planning, testing, and implementation of modifications to a system, aiming to minimize disruptions and risks
What is Change Management
This is a legal agreement, often signed between parties, that outlines the terms and conditions regarding the non-disclosure of sensitive information
What is a non disclosure agreement NDA
This term is used to describe a network for personal devices such as smartphones, tablets, and laptops, typically covering a short range, often within an individual's personal workspace or immediate vicinity
What is a Personal Area Network PAN
This is the term for a route that is used when there is no specific entry in the routing table for the destination IP address, serving as a fallback path to ensure that traffic can still be forwarded when no matching route is found?
What is a Default Route or Route of Last Resort
The IEEE standard for Gigabit Ethernet over twisted pair copper wiring, specifically utilizing four pairs of Category 5e, Category 6, or Category 6a cables
What is 1000BASE-T
This term refers to the maximum data transfer rate of a network or internet connection, often measured in bits per second (bps)
What is Bandwidth
A formal agreement specifying the standards a customer can expect from a service provider, including performance metrics, response times, and penalties for non-compliance
What is a service level agreement SLA
This dedicated communication line reserved for exclusive use between two points is often considered a reliable and secure option for businesses requiring constant and high-bandwidth connectivity.
This dynamic routing protocol, often used in small to medium-sized networks, employs a distance-vector algorithm to determine the best path to a destination by measuring the number of hops
What is RIP Routing Internet Protocol?
The physical or logical point that separates a service provider's network from the customer's network
What is Demarcation Point
This is a technique that involves using redundant links for data transfer between a server and storage device to enhance reliability, increase bandwidth, and provide failover capabilities
What is Multipathing
This is a kin to a handshake agreement representing a non-binding agreement outlining the terms and understanding between parties
What is a Memorandum of Understanding MOU
This technique is employed to map multiple private IP addresses to a single public IP address, enhancing security and conserving IPv4 address space.
What is Network Address Translation NAT
This link-state routing protocol, commonly utilized in large-scale networks, calculates the shortest path to a destination based on a cost metric
What is Open Shortest Path First OSPF
This is a device used to create and manage multiple VPN connections, typically handling the encryption and decryption of data, facilitating secure communication between remote users and a private network
What is a VPN Concentrator
This is the term for the delay introduced in data transmission, often measured in milliseconds, and is a critical factor affecting the responsiveness of applications
What is Latency
The process of evaluating and gathering information about the characteristics of a specific location, such as signal strength, interference, and physical obstructions, to design and deploy a wireless network effectively
What is a Site Survey
This is a cabling technology commonly used for short-distance, high-speed data connections, often employed in data centers and storage area networks, recognized by its paired wires surrounded by a protective shield
What is Twinaxial
This advanced distance-vector routing protocol developed by Cisco, known for its efficient use of bandwidth and rapid convergence in dynamically changing network conditions
What is Enhanced Interior Gateway Routing Protocol EIGRP
This is the international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable television (CATV) system, widely used for providing internet access via cable networks
What is DOCSIS
A structured database that stores parameters and control information for network management, used with protocols like SNMP (Simple Network Management Protocol)
What is a Management Information Bases MIB
The comprehensive strategy outlining procedures and processes that an organization follows to ensure essential functions can continue during and after a disaster or other significant disruptions
What is Business Continuity Plan BCP
