Emma is studying the design of twisted-pair cables for her electronics project. What is the primary purpose of twisting the wires in these cables?

• To increase the data transmission speed

• To reduce electrical noise and interference

• To improve the cable's flexibility

• To decrease the cable's overall diameter

Sophia is setting up a new network in her office and needs to connect several computers using unshielded twisted pair (UTP) cables. Which connector should she use for these cables?

• RJ-11

• RJ-45

• BNC

• SC

Evelyn is setting up a new office network and needs to choose the right type of twisted-pair cable for her Ethernet connections. Which type should she select?

• Category 1

• Category 3

• Category 5

• Category 6

Grace and Evelyn are discussing the advantages of different networking cables for their school project. What is the main advantage of UTP cables over other networking media?

• Lower cost per meter

• Higher data transmission speed

• Greater resistance to electrical noise

• Longer maximum cable length

Jackson is working on a project that involves setting up a network in his classroom. He wants to ensure that the data transmission is not affected by electrical noise. How does shielded twisted-pair (STP) cable reduce electrical noise?

• By twisting the wires together

• By using a metallic foil to wrap each pair of wires

• By increasing the cable's overall diameter

• By using a woven copper braid as the outer conductor

Anika is setting up a new Ethernet network for her school project and needs to know which type of cable can run approximately 500 meters in length.

• UTP cable

• Coaxial cable

• Fiber-optic cable

• STP cable

Priya is considering using coaxial cable for her home network. What is the disadvantage of using coaxial cable compared to twisted-pair cables?

• Higher cost per meter

• Limited data transmission speed

• Greater susceptibility to electrical noise

• Shorter maximum cable length

Mia is setting up a network for her school project and needs to choose a cable for the Ethernet backbone due to its transmission length. Which type of cable should she use?

• UTP cable

• Coaxial cable

• Fiber-optic cable

• STP cable

Isla is setting up a new home theater system and is using coaxial cable to connect her devices. What is the purpose of the metallic shielding in the coaxial cable?

• To increase data transmission speed

• To reduce electrical noise and interference

• To improve the cable's flexibility

• To decrease the cable's overall diameter

During a school project, Zoe and Henry are discussing the best networking media to use for their presentation. They want to choose a type that is typically less expensive than fiber-optic cable. What should they consider?

• UTP cable

• Coaxial cable

• STP cable

• Wireless media
