In bipolar line encoding, which voltage level represents a binary "0," and what is its significance in terms of data transmission?
Positive Voltage; It indicates the start of a data frame.
Negative Voltage; It indicates the end of a data frame.
Zero Voltage (No Voltage Change); It helps maintain synchronization.
Positive Voltage; It represents a binary "1" and is used for data transmission.
In a circuit-switched network, if each connection requires the allocation of a dedicated communication path for the entire duration of the call, which of the following statements is true?
Circuit switching is highly scalable for a large number of connections.
Circuit switching is inefficient for bursty and sporadic communication patterns.
Circuit switching ensures low latency and minimal call setup time.
Circuit switching is the preferred choice for modern packet-switched networks.
In a packet-switched network, which of the following characteristics best describes the behavior of routers or switches when forwarding data packets?
Routers always store and forward entire packets before making any forwarding decisions.
Routers examine the destination address in the packet header to determine the appropriate outgoing link.
Routers divide incoming data into fixed-size chunks before forwarding.
Switches make real-time decisions on forwarding based on the contents of the entire packet.
In a computer network, which of the following statements is true regarding guided and unguided media?
Guided media is always faster than unguided media.
Unguided media is more secure for data transmission.
Guided media requires physical connections, while unguided media uses wireless transmission.
Both guided and unguided media are immune to electromagnetic interference.
In a computer network, which of the following statements accurately represents the characteristics of digital and analog signals?
Analog signals are immune to noise and interference, while digital signals are more susceptible.
Digital signals are continuous and can represent an infinite range of values, while analog signals are discrete and represent a limited range.
Digital signals are more efficient in terms of bandwidth usage compared to analog signals.
Analog signals are typically used in modern high-speed data transmission technologies, while digital signals are primarily used in older, legacy systems.
Which network device primarily operates at Layer 2 (Data Link Layer) of the OSI model, providing segmentation of collision domains and forwarding based on MAC addresses?
Router
Switch
Hub
Bridge
When you type a website's URL into your web browser and hit Enter, what is the first step your computer takes in establishing an internet connection?
Your computer sends an ARP (Address Resolution Protocol) request to the local router.
Your computer performs a DNS (Domain Name System) resolution to convert the URL to an IP address.
Your computer establishes a TCP (Transmission Control Protocol) connection to the web server.
Your computer sends a DHCP (Dynamic Host Configuration Protocol) request to obtain an IP address.
In a communication scenario where two devices can transmit and receive data but not simultaneously, which mode of communication best describes this setup?
Simplex
Half-Duplex
Full-Duplex
Multiplex
