Computer Hardware and Networking Basics Quiz

Subnet Mask in Networking

• Defines a range of IP addresses within a network.
• Helps segment networks into smaller subnetworks, improving efficiency and security.

Function of a Network Switch

• Connects devices within a local area network (LAN) and directs data traffic efficiently.
• Operates at the data link layer, forwarding frames based on MAC addresses.

Common Output Devices for Computers

• Printers and monitors are typical output devices for producing visual or hard copy data.

Linux Command 'ls'

• Lists files and directories in the current working directory.
• Provides basic information about files such as names and types.

Characteristics of a Virtual Machine

• Functions as an independent computer system within a host environment.
• Can run its own operating system and applications as if it were a physical machine.

Common Features of Network Firewalls

• Monitors and controls incoming and outgoing network traffic based on security rules.
• Can block unauthorized access while allowing legitimate communication.

Purpose of an Ethernet Switch

• Facilitates communication between different devices in a wired network.
• Reduces collision domains by creating a separate domain for each connected device.

Component Providing IP Addresses

• A DHCP server (Dynamic Host Configuration Protocol server) assigns IP addresses dynamically to devices on the network.

'Ping' Command in Networking

• Tests connectivity to another network device by sending ICMP echo request packets.
• Measures round-trip time and determines if a device is reachable.

Role of a Virtual Machine Hypervisor

• Manages multiple virtual machines on a single physical machine.
• Allocates system resources like CPU, memory, and storage to each virtual machine.

Linux Command 'ls -l'

• Displays a detailed list of files and directories, including permissions, ownership, size, and modification time.

Hard Copy Output Devices

• Printers are commonly used to produce permanent copies of digital documents.

Primary Purpose of a Network Router

• Forwards data packets between different networks.
• Connects multiple networks and determines the best path for data transmission.

Key Function of a Network Firewall

• Protects networks from unauthorized access and threats.
• Can enforce security policies and filter traffic.

Role of an Ethernet Cable

• Connects network devices, enabling data transmission over a wired connection.
• Transfers signals between devices in local area networks.

Function of a Network Hub

• Connects multiple Ethernet devices into a single network segment, allowing them to communicate.
• Operates at the physical layer and replicates incoming signals to all ports, leading to collisions.

Bandwidth in Networking

• Refers to the maximum rate of data transfer across a network connection.
• Measured in bits per second (bps), it indicates the capacity of the network and affects the speed of data transmission.
