STIG Intro Packet Switching - Asher Levin | Biblioteka

1

In the mail analogy, splitting a book into separate envelopes reduces the risk of total loss. In computer networks, which hidden trade-off of packet switching most closely matches this idea?

Packets may arrive out of order, requiring reassembly

Packets always take the same path, causing congestion

Packets are compressed before transmission, reducing size

Packets cannot be resent if lost

1

The entire movie is resent from the beginning

Your device requests only the missing packet again

The missing packet is ignored, causing a permanent gap

Netflix waits until all packets are confirmed before sending more

1

Packet switching reroutes packets automatically, while circuit switching fails until a new connection is made

Packet switching stops transmitting until the router restarts, while circuit switching instantly reroutes

Both systems fail completely until manual intervention

Packet switching and circuit switching both use the same rerouting strategy

1

It queues Alice’s packets until Bob finishes his call

It sends packets from both streams interleaved across the same network “roads”

It creates two separate dedicated circuits: one for Netflix and one for Zoom

It prioritizes video packets and discards audio packets

Data payload

Router congestion status

IP address and sequence number

Compression algorithm type

Packets contain redundant data that rebuilds corrupted files without retransmission

If one path fails, packets automatically seek alternative paths to the destination

Routers always store a backup copy of every packet they forward

Devices predict missing data instead of requesting it
