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  : …………………....

Text Excerpt:

A network switch operates at the data link layer of the OSI model. It receives incoming data frames, mac-addresses the source, and forwards the data exclusively to the target port.

Which language feature is predominantly shown by the bold verbs (operates, receives, forwards)?

Text Excerpt:

Data security is crucial in modern networks. First, sensitive files are encrypted by the server before transmission. Then, the encrypted data is protected against unauthorized interception.

Why does explanatory text frequently use the passive voice (are encrypted, is protected)?

Text Excerpt:

In a fiber optic connection, electrical signals are converted into light pulses by a transmitter.

What specific sentence pattern/voice is demonstrated in the excerpt?

Text Excerpt:

When a user types "google.com" into a web browser, the computer cannot understand the text directly. A DNS (Domain Name System) server steps in to translate that human-readable domain name into the corresponding machine-readable IP address.

How does a DNS server assist internet navigation based on the text?

Text Excerpt:

Unlike a simple hub that broadcasts data to all ports blindly, a network switch maintains a MAC address table. It examines incoming frames and forwards data packets only to the specific port connected to the destination device.

Based on the text, how does a switch handle data traffic efficiently?

Sammy  : Sir, how do routers running OSPF dynamically choose the best path when multiple network routes are available?

Tedy      : They calculate the shortest path using an algorithm based on link costs, which are determined by interface bandwidth.

Sammy  : What happens step-by-step when a main link suddenly fails in that dynamic network topology?

Tedy      : ……………………..

Student   : Why does a network switch perform much better than an older network hub in a busy lab?

Teacher  : Because a hub broadcasts every data packet to all ports, whereas a switch is more intelligent.

Student   : How does the switch handle the data packet specifically?

Teacher  : …………………........................

Text Excerpt:

Student A writes about "How a Fiber Optic Cable Transmits Data Using Light Pulses". Student B writes about "My unforgettable holiday trip to Bali".

Which topic is appropriate for an explanatory text in TKJ?
