1.2.3 How data transfers over different types of network

Front

Differences between LAN and WAN

Back

LAN (Local Area Network) is a network that is limited to a small geographic area, like a single building or campus. WAN (Wide Area Network) covers a broad area, such as multiple buildings or cities.

Front

Purpose of protocols in networking

Back

Protocols are rules that determine how data is transmitted and received over a network, ensuring reliable and secure communication.

Front

Computer network operation

Back

The process of managing and maintaining a network, including data transmission, connectivity, and resource sharing.

Front

Network topologies

Back

The arrangement of different elements (links, nodes, etc.) in a computer network. Common topologies include bus, star, and ring.

Front

Internet, extranet, and intranet

Back

Internet is a global network accessible to anyone. Extranet is a private network accessible to authorized external users. Intranet is a private network accessible only to an organization's staff.

Front

Devices within a network

Back

Devices such as routers, switches, and hubs that facilitate communication and data transfer within a network.

Front

How data is transferred over a network

Back

Data is transferred over a network using packets, which are small units of data transmitted over network protocols.

Front

Potential threats to data transfer

Back

Threats include packet sniffing, where unauthorized users intercept data packets to access sensitive information.

Front

Cloud computing vs in-house servers

Back

Cloud computing involves storing and accessing data over the internet, while in-house servers store data on local servers within an organization.

Front

Emerging technologies in networking

Back

New advancements in networking technology, such as 5G, IoT (Internet of Things), and AI-driven network management.
