Study Notes
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.
