IB Computer Science Topic C.3.3 Hardware for Distributed Networks Revision Notes (SL/HL) | RevisionDojo

Network Interface Cards (NICs)

Network Interface Cards (NICs) are essential for connecting computers to a network.
They can be wired (Ethernet) or wireless (Wi-Fi).

Note

NICs handle the physical and data link layers of the OSI model, ensuring data is transmitted correctly between devices.

Routers and Switches

Routers direct data packets between different networks, while switches manage data flow within a single network.
Routers use routing tables to determine the best path for data, while switches use MAC addresses to forward data to the correct device.

Example

In a home network, a router connects your devices to the internet, while a switch might connect multiple computers in an office.

Servers

Servers are powerful computers that provide resources, services, or data to other devices (clients) on the network.
Types of servers include web servers , file servers , and database servers.

Note

Servers often have redundant power supplies and RAID storage to ensure reliability and uptime.

Storage Devices

Distributed networks use various storage solutions, such as Network Attached Storage (NAS) and Storage Area Networks (SAN).
