Introduction to Network Hardware

Which statement best defines network hardware?

• Security policies that protect shared resources

• Wireless signals that travel through the internet

• Physical components that connect devices to networks

• Software services that manage user accounts

A school wants students to access shared files and printers. Which setup correctly assigns roles?

• Printers are clients, students are servers

• File server provides services, student laptops are clients

• Teachers are users, servers are wireless signals

• Students are servers, printer is a user

Which statement best defines communication media in a network?

• Physical or wireless links connecting devices

• Software tools managing device drivers

• Cloud platforms storing user backups

• Security policies blocking unauthorized access

A home network advertises 300 Mbps. What does this number primarily indicate?

• The physical distance between connected devices

• The speed of light through fiber cables

• How much data per second can be transferred

• The number of users allowed to join the network

You must upload large files reliably during class. Which setup is most suitable and why?

• Use Bluetooth since it guarantees faster bandwidth

• Use cellular data because it reduces network capacity

• Use public Wi‑Fi because bits travel at light speed

• Use a wired connection for higher, more stable capacity

Which component lets a computer send and receive data over a wired network?

• Smartphone hotspot using mobile data

• Wireless access point using radio waves

• Network interface card with cable connector

• Router that only forwards Wi‑Fi signals

A school wants students’ Wi‑Fi devices to join the campus network without cables. What device should be installed?

• Network interface card inside each router

• Wireless access point creating radio network

• Ethernet switch for wired connections

• Bluetooth beacon for short-range pairing

Which device forwards data packets within a local area network using MAC addresses?

• Router using private IP addresses for LAN

• Modem converting digital signals for ISP

• Switch using unique MAC addresses per device

• Firewall using security rules for traffic

A home network needs to send local traffic to the internet and receive inbound data back. Which address pairing correctly describes how the router handles this?

• Private MAC for WAN, public IP for LAN

• Public MAC for WAN, private MAC for LAN

• Public IP for WAN, private IP for LAN

• Private IP for WAN, public IP for LAN

Which statement best defines a network protocol?

• Formal rules that guide human computer technicians

• Formal written rules that let computers communicate

• Hardware parts that boost network signal strength

• Informal habits computers follow when sharing files
