Networking Concepts Class 8

What are the different types of networks?

• LAN, WAN, WLAN, MAN, VPN

• LAN, PAN, SAN, CAN, DAN

• Ethernet, Bluetooth, USB, HDMI, VGA

• Intranet, Extranet, Internet, Ethernet, Bluetooth

Explain the concept of network topologies.

• Network topologies refer to the physical location of a computer network's server room

• Network topologies define the layout of a computer network, including how different nodes are connected and communicate with each other.

• Network topologies do not impact the performance of a computer network

• Network topologies are only relevant for small-scale networks

What are the main aspects of network security?

• Customer service, marketing strategies, and product design

• Software development, cloud computing, and data storage

• Access control, data encryption, firewalls, antivirus software, intrusion detection systems, and regular security updates

• Network speed, server location, and bandwidth

Describe the network architecture.

• The network architecture is solely focused on software and does not involve any hardware components.

• The network architecture typically includes components such as routers, switches, firewalls, and servers, as well as the network topology and communication protocols.

• The network architecture is only about the physical layout of the network cables and devices.

• The network architecture does not include any communication protocols, it is only about the physical components.

List some common networking components.

• keyboards, monitors, mice

• printers, scanners, copiers

• routers, switches, hubs, network interface cards (NIC), modems, cables

• speakers, microphones, webcams

What are the advantages of networking?

• Increased cost and complexity

• Limited access to information

• Advantages of networking include resource sharing, communication, collaboration, and new opportunities.

• Decreased productivity and efficiency

What is a LAN and how does it differ from a WAN?

• LAN is a wireless network, while WAN is a wired network.

• LAN is a local network that covers a small area, while WAN is a wide network that covers a large geographical area.

• LAN has slower internet speed, while WAN has faster internet speed.

• LAN is used for personal use, while WAN is used for commercial use.

Explain the star network topology.

• In a star network topology, all devices are connected in a linear chain.

• A star network topology involves a single central device that controls all communication.

• In a star network topology, all devices are connected to a central hub or switch.

• In a star network topology, all devices are connected to each other in a circular manner.

What are some common network security threats?

• Malware, phishing, ransomware, DDoS attacks, insider threats, insecure network protocols

• SQL injection

• Trojan horse

• Spyware

How does networking help in resource sharing?

• Networking helps in resource sharing by limiting the number of devices that can connect and share resources

• Networking helps in resource sharing by creating barriers between devices, making it difficult to share resources

• Networking helps in resource sharing by slowing down the transfer of files and data

• Networking helps in resource sharing by allowing devices to connect and communicate with each other, enabling the sharing of files, printers, and internet connections.
