Networking and Web Fundamentals

What is a star topology in networking?

• A star topology connects nodes in a linear fashion.

• A star topology is a wireless network configuration without any physical connections.

• A star topology has no central device and connects nodes directly to each other.

• A star topology is a network layout where all nodes are connected to a central hub or switch.

Describe the characteristics of a bus topology.

• All devices are connected in a star configuration.

• Data transmission occurs only in one direction.

• Characteristics of a bus topology include a single central cable, data transmission in both directions, all devices connected to the bus, simplicity in setup, lower cable requirements, and vulnerability to failure if the bus is damaged.

• The topology requires extensive cabling for setup.

Identify the advantages of a ring topology.

• Complex fault isolation

• Unpredictable data transmission times

• Advantages of a ring topology include reduced data collisions, predictable data transmission times, and easier fault isolation.

• Increased data collisions

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

• To route data between different networks.

• To store data for network applications.

• To connect devices within the same network.

• To provide internet access to devices.

Explain the difference between a LAN and a WAN.

• A LAN is a network for a small area, while a WAN connects larger geographical areas.

• A LAN is a type of WAN.

• A LAN connects multiple countries while a WAN is local.

• A WAN is only used for wireless connections.

What are the key features of a mesh topology?

• Low performance

• Single point of failure

• Limited connectivity

• Key features of a mesh topology include full connectivity, redundancy, reliability, high performance, and fault tolerance.

How does a hybrid topology combine different types?

• A hybrid topology only uses one type of network.

• A hybrid topology is a purely wireless network.

• A hybrid topology eliminates the need for any physical connections.

• A hybrid topology combines different types by integrating multiple topologies to utilize their strengths.

What protocol is used for transferring files over the internet?

• File Transfer Protocol (FTP)

• Post Office Protocol (POP)

• Simple Mail Transfer Protocol (SMTP)

• Hypertext Transfer Protocol (HTTP)

Explain the purpose of the HTTP protocol.

• To establish a secure connection for online banking.

• The purpose of the HTTP protocol is to enable communication between clients and servers for transferring web content.

• To optimize the loading speed of images on websites.

• To manage user authentication for web applications.

What is the role of HTTPS in web communication?

• HTTPS is used to speed up web page loading times.

• HTTPS is a protocol for transferring files between servers.

• HTTPS is primarily for managing user accounts on websites.

• HTTPS secures web communication by encrypting data and ensuring secure connections.
