Computer Network Device Tutorial

Which of the following best defines networking software?

• A wireless protocol for internet connectivity

• A physical cable used to connect devices

• A set of tools that manage and control network hardware and operations

• A hardware device that connects computers in a network

Answer explanation

A computer network is a system that connects numerous independent

computers in order to share information (data) and resources. Meanwhile, Networking software is defined as a wide range of software that streamlines the operations, design, monitoring, and implementation of computer networks.

In the components of network software, which layer links the application layer and the infrastructure layer?

• Session layer

• Data link layer

• Control layer

• Transport layer

Answer explanation

This is not the process of computer network. This is how each layer of network software components interact to each other.

Which of the followings functions of network software?

• User management

• Image editing

• File compression

• Network security

Answer explanation

User management: allows administrator to add or remove users from the network

Image editing: it is a function of graphic design or photo editing software.

File compression: this task is typically handled by separate compression tools.

Network security: assist in protecting the network by identifying and mitigating potential threats and vulnerabilities.

What is the primary function of a router in a network?

• To amplify network signals

• To filter malicious software

• To direct data packets between networks

• To monitor internet speeds

Answer explanation

Routers link multiple networks, directing data packets based on IP addresses. They determine the best paths for data, enabling communication between different network segments, including internet access.

The primary function of a modem is to convert digital signals from a computer into analog signals for transmission over telephone lines (modulation) and to convert incoming analog signals back into digital signals (demodulation) for the computer to process. This allows devices to connect to the internet and communicate over long distances.

Which type of networking device is essential for connecting multiple computers in a local area network (LAN)?

• Access Point

• Router

• Modem

• Switch

Answer explanation

The switch manages communication between devices within the school office, ensuring efficient internal operations. The router acts as the gateway for internet access, enabling external communication and resource access. Together, they create a seamless network for both internal and external connectivity.

switch connects all office devices (e.g., staff computers, printers, and file servers) into a local area network (LAN), like printers, teacher's computer and file server

routers connects the office's LAN to the internet, allowing the school staff to access online resources, send emails, or manage cloud-based tools like e-learning

Which networking device is used to convert digital signals to analog for transmission over phone lines?

• Hub
• Modem
• Router
• Switch

Answer explanation

device that enables communication between your local network and the internet by converting different types of signals. It acts as a bridge between your home, school, or office and your Internet Service Provider (ISP).

What is one key advantage of networking software in educational networks?

• Simplifies collaboration and resource sharing

• Increases the need for physical hardware

• Reduces the speed of data transmission

• Eliminates the need for network security

Answer explanation

Computer networks are the future of education and the uses of computer network in education offer a lot of benefits to both students and teachers.

A firewall can be a hardware or software-based network security device

• True

• False

Answer explanation

A firewall is a network security system that monitors and controls incoming and outgoing traffic based on predefined security rules. Its primary purpose is to act as a barrier between a trusted internal network (like your home, school, or office network) and untrusted external networks (like the internet) to prevent unauthorized access and cyber threats.

Networking software is used to only configure IP addresses on devices

• True

• False

Answer explanation

Networking software is used for managing and monitoring networks, configuring devices, ensuring network security, and more

Switches and hubs perform the same function in a network.

• True

• False

Answer explanation

Switches are more intelligent than hubs, as they can direct data to specific devices rather than broadcasting to all
