Prelim Examination: Networks and Communication

What is a primary disadvantage of traditional peer-to-peer networks as they grow larger?

• They require extensive technical knowledge for setup.

• They become overly expensive to maintain.

• They become difficult to modify or expand.

In a client/server network, what role does the server typically play?

• It primarily acts as a data transmission medium.

• It manages shared resources and ensures efficient data processing.

• It functions as a standalone processing unit without network interaction.

What is the primary function of a network operating system (NOS)?

• To allocate IP addresses to connected nodes.

• To manage data and user access among clients.

• To provide network topology design.

Which organization is responsible for setting international technological standards?

• EIA (Electronic Industries Alliance)

• ISO (International Organization for Standardization)

• ANSI (American National Standards Institute)

How does the OSI model organize network communications?

• Through five layers focusing on server-client interactions.

• Through four sections dedicated to data encryption and security.

• Through seven layers including Physical and Application.

Which network protocol is NOT typically associated with ensuring secure data transmission?

• FTP

• HTTPS

• SSL

What distinguishes the OSI Model from the TCP/IP Model in terms of layers and practical use?

• OSI is seven-layer, theoretical; TCP/IP is four-layer, practical.

• OSI has four layers, TCP/IP has seven, both are practical.

• Both models have seven layers and practical applications.

Which of the following is NOT a responsibility of the Transport Layer in the TCP/IP Model?

• Providing reliable or unreliable delivery

• Managing data flow control

• Handling logical addressing of packets

In the OSI Model, which layer is specifically responsible for managing routing and forwarding of data packets?

• Transport Layer

• Data Link Layer

• Network Layer

Why is UDP suited for video streaming applications like live sports viewing on YouTube?

• Guarantees accurate data delivery in order

• Offers encryption for secure delivery

• Provides faster, low-latency data delivery
