10 Questions
What is the primary difference between a LAN and a WAN?
A LAN is generally confined to a limited geographical area, whereas a WAN covers a large geographical area.
Define data communication according to the text.
Data communication refers to the exchange of data between a source and a receiver.
Provide an example of a network mentioned in the text.
The Internet, which connects millions of people all over the world.
What is the function of networks according to the text?
To allow the sharing of data.
What do WANs consist of according to the text?
Most WANs are made up of several connected LANs.
What is a Personal Area Network (PAN)?
A computer network that enables communication between computer devices near a person.
What are the advantages of using a Wireless Local Area Network (WLAN)?
WLANs use radio, infrared, and microwave transmission to transmit data from one point to another without cables. Therefore, WLAN offers a way to build a Local Area Network without cables.
What are the risks to the security of a computer network?
Equipment malfunctions, system failures, computer hackers, and virus attacks.
How does a Local Area Network (LAN) enable cost-effective resource sharing in an office?
In an office connected via LAN, hardware and software resources like printers, FAX, drivers, and hard-disk are shared, making it cost-effective.
What is the collaborative advantage of a LAN network?
LAN network works as a client-server model, allowing data to be stored centrally on one PC called a server.
Study Notes
Network Fundamentals
- A LAN (Local Area Network) is a computer network that spans a small geographical area, usually within a building or campus, whereas a WAN (Wide Area Network) covers a larger geographical area, such as cities or countries.
Data Communication
- Data communication is the transmission and reception of data between devices through a medium, such as cables or wireless links.
Network Examples
- Example of a network: A company's office network, which connects computers and devices within the office building.
Network Functions
- The primary function of networks is to enable communication, resource sharing, and information exchange between devices.
WAN Composition
- WANs consist of multiple LANs connected through routers, switches, and other networking devices.
Personal Area Network (PAN)
- A PAN is a computer network used for communication among devices close to a person's body, such as a wireless headset and smartphone.
Wireless Local Area Network (WLAN) Advantages
- WLANs offer advantages such as mobility, ease of installation, and cost-effectiveness.
Network Security Risks
- Risks to computer network security include unauthorized access, data breaches, and malware attacks.
LAN Cost-Effective Resource Sharing
- A LAN enables cost-effective resource sharing in an office by allowing multiple devices to share printers, files, and internet connections.
Collaborative Advantage of LAN
