9th Computer Science Chapter5 Computer Networks

Sr #	Questions	A	B	C	D
1	Which network topology is most commonly used in Ethernet LANs?	Bus topology	Ring topology	Star topology	Mesh topology
2	Which network topology uses a single, continuous cable with each device connecting directly to it?	Bus	Ring	Star	Mesh
3	Which type of modem allows digital data to be transmitted over analog telephone lines?	DSL modem	Cable modem	Dial-up modem	Fiber modem
4	Point-to-point networks are characterized by:	Centralized control of network resources	Each node being directly connected to every other node	Nodes communicating through a central server	Nodes communicating through a series of switches and routers
5	Which of the following is a commonly used communication technology for voice transmission over telephone networks?	Modem	Ethernet	VoIP	Router
6	What advantage does a fiber-optic communication line have over a twisted-pair copper cable?	Fiber-optic cables are more prone to interference.	Fiber-optic cables can transmit data over longer distances without signal degradation.	Fiber-optic cables are less expensive to install.	Fiber-optic cables are less secure.
7	What is a characteristic of peer-to-peer networks?	They rely on a centralized server for resource management.	Each node can function as both a client and a server.	They are primarily used in large-scale enterprises.	They have high security vulnerabilities.
8	Which network type is designed for personal devices within a short range, such as Bluetooth-connected devices?	LAN (Local Area Network)	WAN (Wide Area Network)	MAN (Metropolitan Area Network)	PAN (Personal Area Network)
9	In a ring network topology, how are devices connected to each other?	In a circular configuration with each device connected to two others	Through a central hub with each device connected directly to it	In a star configuration with each device connected to a central switch	Through a series of interconnected cables with no specific order
10	What is a typical advantage of client/server networks over peer-to-peer networks?	Lower initial setup cost	Higher scalability and centralized management	Faster data transmission speed	Increased privacy and security
11	In a star network topology, what is the central connecting point for all devices?	Switch	Router	Hub	Server
12	Which topology is best suited for large networks with high fault tolerance requirements?	Bus topology	Ring topology	Star topology	Mesh topology
