Network Fundamentals
This type of network covers a small geographic area, such as a school or office.
What is a LAN (Local Area Network)?
This set of rules ensures that devices on a network can communicate effectively.
What is a protocol?
The term for breaking data into smaller units for transmission across networks.
What is packet switching?
A unique identifier assigned to network devices for authentication.
What is a MAC address?
This is a common wireless technology used for home and business networks.
What is WiFi?
A network type that connects multiple LANs across cities, countries, or even continents.
What is a WAN (Wide Area Network)?
This protocol is used for securely transferring web pages.
What is HTTPS (Hypertext Transfer Protocol Secure)?
A key reason for compressing data before transmission.
What is reducing file size and transmission time?
This security method scrambles data so only authorized users can read it.
What is encryption?
A security method used in wireless networks that encrypts data.
What is WPA2 (Wi-Fi Protected Access 2)?
This type of network allows devices within close proximity, like Bluetooth connections.
What is a PAN (Personal Area Network)?
This protocol is used for sending email messages.
What is SMTP (Simple Mail Transfer Protocol)?
This term refers to how quickly data is sent from one device to another.
What is data transmission speed?
This network security method requires users to provide credentials before accessing a system.
What is user authentication?
The main advantage of a wireless network compared to a wired network.
What is mobility/flexibility?
This type of network is created by partitioning a physical network into multiple logical networks.
What is a VLAN (Virtual Local Area Network)?
This protocol ensures the reliable delivery of data packets.
What is TCP (Transmission Control Protocol)?
These factors can cause variations in data transmission speed.
What are network congestion, bandwidth, and distance (latency)?
A common type of attack where unauthorized access is attempted by guessing passwords.
What is a brute force attack?
A disadvantage of wireless networks related to performance.
What is interference and lower speed?
This type of network enables businesses to connect securely over public networks, such as the internet.
What is a VPN (Virtual Private Network)?
This is the most commonly used protocol for resolving domain names into IP addresses.
What is DNS (Domain Name System)?
This is the term for a method of error checking that ensures data is transmitted correctly.
What is checksum or error detection?
This type of firewall examines the contents of data packets for security threats.
What is a deep packet inspection firewall?
A common method of securing a wireless network besides encryption.
What is MAC address filtering?
