IT Infrastructure and Networking
Concepts QUESTIONS AND ANSWERS
Throughput - ANSWER>>Refers to how fast customers are served and get in and
out with their items.
Jet engines data generation - ANSWER>>Jet engines produce data equivalent to
1600 iPhones per hour.
Architecture - ANSWER>>Analogized to the DNA of a system, with irreversible
consequences.
Services and delivery - ANSWER>>Involves analyzing preferences, predictive
analytics, and testing new flavors.
Circuit vs packet switching - ANSWER>>Contrasts fixed paths (circuit) with routing
data in addressed packets (packet).
TCP/IP 'stack' - ANSWER>>Refers to the layering of communication protocols for
reliable data transmission.
IT Infrastructure Importance - ANSWER>>Critical for transforming industries,
nations' fates, medical care, and warfare.
Infrastructure Profit - ANSWER>>Backbone firms' profits exceed those of major
internet companies.
Cybersecurity Risks - ANSWER>>Poor infrastructure can lead to vulnerabilities like
interconnected refrigeration and cash registers.
Trans-Atlantic Cable - ANSWER>>Historical cable system for transatlantic
communication.
, IT Infrastructure Definition - ANSWER>>Foundation for data flow, connecting
applications with hardware and networks.
Telegraph Contribution - ANSWER>>Introduced signaling, converting information
to energy for transmission.
Multiplexing - ANSWER>>Sending multiple messages over a single path, a key
advancement in IT infrastructure.
Switching - ANSWER>>Transmitting data between selected points, involving
circuit and packet switching methods.
Circuit switching - ANSWER>>A dedicated path among two points, typically billed
by the minute and inefficient at handling bursts of data.
Packet switching - ANSWER>>Packet switches ("routers") connect two or more
networks, typically billed by MB and better at handling data bursts.
Burstiness - ANSWER>>Short periods in which large volumes of data are uploaded
or downloaded by the user followed by long periods of minimal activity.
Packetization - ANSWER>>The process of breaking down user data into small
segments and packaging these segments appropriately for delivery and
reassembly across the network.
Packet overhead - ANSWER>>Additional information added during packetization
to aid in the delivery to the correct destination, discarded once packets are
processed by the receiver.
TCP/IP stack - ANSWER>>A multi-layer protocol where layers divide tasks for
communication, enabling compatibility and working with yet-to-be-invented
technologies.
