12 CSC ATAR - Networks

This communications standard, which operates at the Transport layer of the DoD model, allows for transmitted data that is sequenced, error-corrected, and retransmitted if packets fail to arrive.

• Transmission Control Protocol (TCP)

• User datagram protocol (UDP)

This communications standard, which operates at the Transport layer of the DoD model, supports delivering continuous data (broadcasting), is "connectionless" (no connection to start and end a data transfer), and is suited for applications such as live streaming and video chat.

• Transmission Control Protocol (TCP)

• User datagram protocol (UDP)

This standard of Internet Protocol address (IP address) is represented by four 8-bit fields (octets) separated by periods.

• IPv4

• IPv5

• IPv6

This standard of Internet Protocol address (IP address) is represented by eight 16-bit hexadecimal fields, separated by colons.

• IPv4

• IPv5

• IPv6

This type of network equipment can buffer the transmission of Ethernet frames, preventing packet collisions.

• Router

• Switch

• Hub

• Modem

This range of port numbers are known as 'system' or 'well-known' ports, and are used by system processes that provide widely used types of network services, e.g. FTP, TCP/IP, DNS.

• 0 to 1023

• 1024 to 49,151

• 49,152 to 65,535

This range of port numbers are known as 'registered' ports, and are registered with and assigned by the Internet Assigned Numbers Authority (IANA) for use with specific software, e.g. Apple QuickTime Streaming Server administration.

• 0 to 1023

• 1024 to 49,151

• 49,152 to 65,535

This range of port numbers are known as 'dynamic', 'private' or 'ephemeral' ports, meaning that they can be used by just about anybody, and are typically used for temporary purposes.

• 0 to 1023

• 1024 to 49,151

• 49,152 to 65,535

The Open Systems Interconnection (OSI) communications model has _ layers.
