A group of isolated computers A group of interconnected computers A single computer with multiple users None of the above None 2. computer network,MCQ The primary purpose of a computer network is: To organize files To connect multiple printers To share resources and information d) To create individual workspaces None 3. computer network,MCQ Which of the following is NOT a type of computer network? LAN MAN NAN WAN None 4. computer network,MCQ In which type of network are all computers connected to a single central cable? Star Network Mesh Network Bus Network Ring Network None 5. computer network,MCQ Which of the following is an advantage of computer networks? Increased hardware costs Data sharing among connected devices educed security threats No need for technical expertise None 6. computer network,MCQ Which of the following is a common application of computer networks in businesses? Email communication Playing single-player games Watching offline videos Using standalone software None 7. computer network,MCQ What type of network is used to connect computers within a single building or campus? Wide Area Network (WAN) Local Area Network (LAN) Metropolitan Area Network (MAN) Personal Area Network (PAN) None 8. computer network,MCQ Which network type spans a large geographical area, such as a city, country, or even multiple countries? Local Area Network (LAN) Personal Area Network (PAN) Wide Area Network (WAN) Campus Area Network (CAN) None 9. computer network,MCQ A network that covers a city and its surrounding areas is referred to as a: Personal Area Network (PAN) Local Area Network (LAN) Wide Area Network (WAN) Metropolitan Area Network (MAN) None 10. computer network,MCQ What is the main difference between a LAN and a WAN? LAN is used for long-distance communication, while WAN is for short-distance communication. LAN connects devices within a small area, while WAN covers a broader geographic area. LAN uses satellite connections, while WAN uses fiber optics. LAN has lower data transfer speeds than WAN. None 11. computer network,MCQ Which of the following is an example of a Local Area Network (LAN)? A network connecting different branches of a bank across a country A network within a university campus A network used by an airline to connect its reservation centers A home Wi-Fi network None 12. computer network,MCQ Bluetooth is an example of which type of network? Local Area Network (LAN) Wide Area Network (WAN) Personal Area Network (PAN) Metropolitan Area Network (MAN) None 13. computer network,MCQ Which of the following is a characteristic of a Wide Area Network (WAN)? High speed within a limited area Covers multiple continents or regions Used only for connecting personal devices Limited to a single building None 14. computer network,MCQ Which topology is characterized by every device being connected to a single central hub? Mesh Star Bus Ring None 15. computer network,MCQ In which topology does each device have a dedicated point-to-point link to every other device in the network? Ring Star Mesh Bus None 16. computer network,MCQ What is a primary disadvantage of using a bus topology? Easy to install Single point of failure Easy to expand High level of redundancy None 17. computer network,MCQ Which topology is typically used in Local Area Networks (LANs) where each computer is connected to a central device like a switch? Star Bus Ring Tree None 18. computer network,MCQ In which topology are the devices connected in a circular sequence? Star Ring Mesh Tree None 19. computer network,MCQ What is the advantage of using a mesh topology? Simple design Low cost of implementation High fault tolerance Easy to troubleshoot None 20. computer network,MCQ Which topology combines characteristics of both star and bus topologies? Mesh Ring Tree Hybrid None 21. computer network,MCQ In which topology is data sent in one direction, reducing the chances of data collisions? Ring Star Mesh Bus None 22. computer network,MCQ If a central device fails, which topology will be most affected? Mesh Ring Star Bus None 23. computer network,MCQ A hybrid topology is a combination of: Bus and Star topologies Mesh and Ring topologies Ring and Tree topologies All of the above None 24. computer network,MCQ Which topology has a hierarchical structure where nodes are arranged in the form of a tree? Star Mesh Tree Ring None 25. computer network,MCQ In a ring topology, if one device fails, what will happen? The entire network goes down Only the failed device is affected Data reroutes to other paths It turns into a bus topology None 26. computer network,MCQ In which topology do all devices share a common communication line? Star Bus Tree Hybrid None 27. computer network,MCQ Which topology provides multiple paths for data transmission to ensure that network traffic is distributed efficiently? Ring Bus Mesh Star None 28. computer network,MCQ In a star topology, what happens if a single peripheral device fails? The whole network collapses Only the failed device is affected Data transmission stops completely A backup path is created None 29. computer network,MCQ Which type of topology is used in most large data centers to provide redundancy and fault tolerance? Star Tree Mesh Bus None Time's up
