TCP/IP Core Protocols
TCP/IP Core Protocols
What is TCP?
This protocol provides reliable, connection-oriented communication.
What is Encryption?
This process converts readable data into unreadable data to protect confidentiality.
What is Remote File Access?
This allows users to access files from another computer over a network.
What is ICMP?
This protocol is commonly used to test connectivity with the ping command.
What is ARP?
This protocol resolves IPv4 addresses to MAC addresses.
What is UDP?
This protocol sends data without establishing a connection first.
What are SSL and TLS?
These two protocols secure web traffic and are commonly seen as HTTPS.
What is Terminal Emulation?
This allows a user to control another computer’s command line remotely.
What is Traceroute (or tracert)?
This tool displays the path packets take to reach a destination.
What is Ethernet?
This is the Layer 2 protocol used on most LANs.
What is IP?
This protocol handles logical addressing and routing across networks.
What is IPsec?
This protocol suite secures network traffic at the IP layer.
What is a VPN?
This secure connection allows remote users to access a private network over the internet.
What is Nmap?
This tool shows open ports and services on a networked device.
What is Neighbor Discovery?
This protocol replaces ARP in IPv6 networks.
What is ICMP?
This protocol sends error and status messages when network issues occur.
What is the Transport Layer?
TLS operates primarily at this OSI layer.
What is Terminal Emulation?
This type of remote access emulates a physical terminal session over a network.
What is the process of elimination?
This troubleshooting step involves isolating variables to narrow down the problem source.
What is a MAC address?
his address type is used by Ethernet to deliver frames within a LAN.
What is the sliding window (or window size)?
This TCP feature controls the amount of data that can be sent before receiving an acknowledgment.
What is Transport Mode?
This IPsec mode encrypts only the payload of the IP packet, not the original IP header.
What is SSL VPN?
This VPN protocol uses port 443 and operates over HTTPS to bypass firewalls.
What is the Network Troubleshooting Methodology?
This troubleshooting model includes steps like identify, establish theory, test theory, and document findings.
What is the Data Link Layer?
ARP operates at this OSI layer.
