Text Excerpt:

After the general introduction defining a router, the text continues with paragraphs detailing how radio waves are captured, translated into packets, and sent to the modem.

What part of the explanatory text structure do these detailed process paragraphs represent?

Fandy   : Why do redundant backup paths in an enterprise network sometimes cause a complete network crash?

Johny    : Because loops cause data frames to circulate endlessly around the network switches, creating a broadcast storm.

Fandy   : How does Spanning Tree Protocol (STP) explain and solve this issue?

Johny    : ……………………...

Text Excerpt:

Paragraph 1: A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.

Paragraph 2: When a packet arrives at the network boundary, the firewall inspects its source IP, port number, and protocol. If the packet matches safe rules, it is permitted to pass. Otherwise, it is blocked.

What is the structural classification of Paragraph 2 in an explanatory text?

Text Excerpt: 

"A network switch operates by reading the destination MAC address contained within incoming data frames..."

What is the primary characteristic of the language style used in technical explanatory texts?

Linda      : How does a stateful firewall differ from a standard packet filter when inspecting network traffic, Sir?

Mr. Arga : A stateful firewall keeps track of the active connection state and context, not just individual packet headers.

Linda      : How does it process an incoming return packet from an external server during an established session?

Mr. Arga : ……………………….

Student  : How do multiple devices in a local network share a single public IP address to access the internet?

Teacher  : They use a translation mechanism called Network Address Translation (NAT).

Student  : What exactly happens to the data packets during this translation process?

Teacher  : …………………....

Le mouvement considéré est celui obtenu par le jet d'un ballon relativement à un repère fixe (O, . Les coordonnées du vecteur vitesse sont notées et . Le vecteur vitesse initiale du ballon forme un angle α avec l'horizontale :

Quelles affirmations sont correctes? 

On lance un projectile depuis le sol avec une vitesse initiale v0v_0​ faisant un angle θ\theta avec l'horizontale. On néglige les frottements de l'air et le projectile retombe sur l'horizontale passant par le point de départ.
