The key characteristic of a Bus network topology is:

All devices share a single communication backbone cable.

Devices are connected in a closed loop.

Every device is connected directly to every other device.

All communication flows through a central switch.

What is the single point of failure in a Star topology?

Any individual cable connecting a device.

Why is Wi-Fi less secure by default than wired Ethernet?

Radio waves are transmitted through the air and can be intercepted outside the physical premises.

Wi-Fi requires a password, while Ethernet does not.

Ethernet signals are easier to jam.

Wi-Fi operates at a lower frequency.

Which statement accurately describes the function of a Server?

It is a resource provider in a client-server relationship.

It regulates the flow of electrical power to network devices.

It translates domain names to IP addresses.

It uses Layer 3 addresses to forward packets across networks.

What happens to the entire network if the main backbone cable in a Bus topology breaks?

The entire network segment loses communication.

Only the two devices nearest the break lose connectivity.

The network automatically reroutes traffic through a backup path.

The central switch redirects traffic.

Ethernet uses which type of physical medium most commonly in modern LANs?

Twisted-pair copper cable (e.g., Cat5e/Cat6)

The term 'modulation' in the context of a modem refers to:

Converting a digital signal to an analog signal.

Routing traffic to different networks.

Forwarding data based on a MAC address table.

Storing data packets temporarily.

A key disadvantage of a Ring topology is that:

A single cable break or failed node can disrupt the entire loop.

It requires the most extensive cabling.

It always suffers from high collision rates.

How does a Switch primarily improve network efficiency compared to an old Hub?

By sending data only to the specific port of the intended destination device.

By assigning IP addresses faster.

By encrypting all data packets.

By connecting to the internet faster.

A Web Server is a type of server that:

Hosts and delivers web pages using protocols like HTTP/HTTPS.

Manages local login credentials.

Provides dynamic IP address assignment.

Converts analog signals to digital ones.

Partial Mesh topology is often implemented instead of a Full Mesh topology because:

Full mesh is prohibitively expensive and complex due to the large number of required links.

Partial mesh has higher redundancy.

Full mesh uses older technology.

Bluetooth is typically limited by:

Short range and relatively low throughput (speed) compared to Wi-Fi.

Dependence on a central router.

Requirement for optical fiber cables.

Which of the following is an advantage of a Bus topology?

Minimal cabling required for small networks

High performance under heavy load

The main purpose of network terminators in a traditional Bus topology is to:

Prevent signals from reflecting back and causing interference.

Route traffic to the correct device.

A DHCP Server is responsible for:

Dynamically assigning IP addresses to network devices.

Translating names into IP addresses.

In what scenario would a Router be preferred over a Switch?

Connecting a Local Area Network (LAN) to a Wide Area Network (WAN).

Connecting 10 computers within the same department.

Reducing collision domains within a single segment.

Forwarding frames based on MAC addresses.

A Print Server manages:

Shared access to one or more network printers.

The biggest drawback of using Wi-Fi for gaming or video conferencing is:

Higher potential for signal interference and latency (lag).

Limited number of connected devices.

Which statement about the Ring topology is false?

Failure of one station does not affect the rest of the network.

Data travels in one direction around the loop.

It often uses a token-passing mechanism.

It can offer fast data transfer speeds if managed correctly.

The primary security challenge with Wired Ethernet is:

Its vulnerability to physical cable tapping or unauthorized port access.

Signal interception outside the building.

Easy access for unauthorized devices to plug into a network port.

Bluetooth's low-power consumption makes it ideal for which type of device?

Battery-operated mobile devices and wearables

Which server type is crucial for users to access websites using easy-to-remember names instead of numerical IP addresses?

DNS Server (Domain Name System)

An Access Point (AP) is primarily used to connect:

Wireless clients to a wired network infrastructure.

What is the primary function of a Network Interface Card (NIC) in a computer?

To provide a physical interface for connecting to a network.

To connect to the internet wirelessly.

To convert digital data into analog signals.

To manage network traffic between devices.

In a network, what does the term 'latency' refer to?

The delay before a transfer of data begins following an instruction.

The strength of the signal being transmitted.

The maximum distance between two connected devices.

The amount of data that can be transmitted in a given time.
