Knowledge
Students know:
- how routers, switches, servers, network topology, packets, and IP addressing affect scalability and reliability of networks.
- how to describe the issues that impact network functionality.
- that the DNS server function is to turn a user
- friendly domain name into an IP address that machines use to identify each other on a network.
- that the DNS server manages a database that maps domain names to IP addresses.
- the typical format of an IP address.
- computers communicate the IP address in binary form.
- that networking protocols are formal standards and policies that include procedures, formats and rules the define how two or more devices will communicate over a network.
- there are several broad types of networking protocols including network communication protocols such as TCP/IP and HTTP, networking security protocols such as HTTPS and SSL, and network management protocols such as SNMP and ICMP.
Skills
Students are able to:
- describe the relationships of routers, switches, servers, network topology, packets, and IP addressing.
- describe scalability and reliability of networks.
- describe issues that impact network functionality.
- explain the purpose of IP addresses.
- identify what a typical IP address look like.
- explain the difference between IP addresses expressed in decimal format and binary format.
- explain how domain names are resolved to IP addresses through a DNS server.
- explain the significance of networking protocols.
- provide examples of common networking protocols.
- explain the uses of different networking protocols.
Understanding
Students understand that:
- scalability and reliability of networks are dependent on relationships between routers, switches, servers, network topology, packets, and IP addressing, etc.
- network functionality is impacted by bandwidth, load, delay, latency, firewalls, server capacity, etc.
- an Internet Protocol address is a unique identifying number for every machine on the internet.
- the DNS server manages a massive database that maps user
- friendly domain names to an IP address.
- networking protocols are needed to define rules for communication between network devices.
- networking protocols include Internet protocols (IP, TCP, HTTP, FTP, SMTP, etc.), wireless network protocols (Wi-Fi, Bluetooth, LTE), and network routing protocols (OSPF, BGP, etc.).
- networking security protocols, such as HTTPS and SSL, provide security over network communications.
- network management protocols, such as SNMP and ICMP, provide network governance and maintenance.
