How do switches and routers differ in their roles within a network?
Press to flip
Switches connect computers within a network for communication, while routers provide wireless connectivity and direct data between different networks.
What are the main types of services provided by a server in a network?
File services, email, internet, web server, print server, database server
What software role is crucial within a network and why?
Network software controls communication and security within a network, ensuring proper management, access, and protection of data.
What is the primary role of a Network Interface Controller (NIC)?
A Network Interface Controller (NIC) is a network card built into computers to enable wired or wireless network connectivity.
Why might fiber optic cables be used instead of UTP or STP?
Fiber optic cables use light signals for longer distances and are not affected by electromagnetic interference from electrical sources.
Why might a mesh topology be chosen despite its complexity?
A mesh topology might be chosen for its high reliability, as each node is directly connected to every other node, providing multiple paths for data transmission.
What visual signs might indicate a device is connected to a network?
Extra drives appearing in File Explorer and a network activity indicator in the notification area.
What are the main advantages of a Local Area Network (LAN)?
Transfer files without physical devices, shared software and hardware, central file storage
What is an Acceptable Use Policy (AUP) and what does it typically include?
An AUP defines rights and responsibilities of network users, including rules on data access, usage limits, and restrictions on installing hardware/software.
Describe the difference between an 'Internet' and an 'Intranet'.
The Internet is a worldwide computer network accessible to anyone, whereas an Intranet is a private network restricted to an organization's members.
What are some methods to prevent unauthorized access and misuse of a network?
Restrict access to confidential files, use usernames and passwords, implement password guidelines (at least 8 characters, mix of letters, numbers, special characters, change regularly)
Explain the differences between UTP and STP cables.
UTP (Unshielded Twisted Pair) cables are vulnerable to electromagnetic interference, while STP (Shielded Twisted Pair) cables are shielded to reduce interference.
List the disadvantages of using a Wireless LAN (WLAN).
Security risks, possible performance reduction, signal loss/interference
Identify and explain the four primary LAN topologies.
Bus Topology: One main cable connects all computers. Star Topology: Each computer connects to a central switch. Ring Topology: Computers connected in a circular fashion; data travels one way. Mesh Topology: Every node connects directly to every other node; high reliability but complex.
Differentiate between a PAN and a HAN.
A PAN (Personal Area Network) is around an individual, whereas a HAN (Home Area Network) is within a home environment.
