Finally, you'll learn about wireless tools, security, authentication, encryption, and performance. This course was originally created by Global Knowledge (GK).

Internet Protocol (IP) is the backbone of internet communication. Subnetting is the process of dividing a network into subnetworks and it's an important part of designing computer networks. In this course, you'll discover IP addressing concepts such as addressing, binary numbering, and dotted decimal notation. Then you'll explore classful addressing, reserved and private addresses, and network masks. You'll learn about classless addressing and the new format for IP addresses, IPv6. You'll explore subnetting and its purpose and subnet mask rules. Then you'll discover the art and the science of subnetting and how to calculate subnets. Finally, you'll learn about key subnet addresses and how to implement a subnet plan. This course was originally created by Global Knowledge (GK).

Transmission Control Protocol/Internet Protocol (TCP/IP) is the underlying communication mechanism of all networked devices. A number of protocols perform specific functions when facilitating network communication. In this course, you'll learn about TCP and User Datagram Protocol and connection-oriented vs. connectionless protocols. Then you'll learn how messages are packaged and source and destination port numbers. You'll learn about Network Address Translation. You'll learn about Address Resolution Protocol, ARP messages, and the ARP cache. Then you'll explore Dynamic Host Configuration Protocol, the Domain Name System, Internet Control Message Protocol, ICMP and the Ping command, and Internet Group Management Protocol. Finally, you'll learn about telnet, Simple Network Management Protocol, and legacy protocols. This course was originally created by Global Knowledge (GK).

Routers play a crucial role in computer networking. Networking technologies have made it possible to implement connectivity over broad geographical areas. In this course, you'll discover the inner workings of routers including logical segmentation, static and dynamic routing and the ways routers make decisions. Then you'll learn about routing metrics and tables. You'll explore the various routing protocols and how basic router configuration is performed. You'll then explore Wide Area Networks (WANs) and their related technologies including WAN providers, circuit-switched and packet-switched networks, and SONET. Then you'll discover Multiprotocol Label Switching (MPLS) and Carrier Ethernet networks. Finally, you'll learn about cloud-based networks and how they can provide connectivity over the internet. This course was originally created by Global Knowledge (GK).

In networking, communications are facilitated using a number of communication protocols. In this course you'll explore the various protocols used for transmitting information including email protocols SMTP, POP3, and IMAP. Then you'll learn about instant messaging and the SIMPLE and XMPP protocols. You'll discover VoIP, SIP, RTP, H.323 and MGCP, and unified communications. There are several protocols used to facilitate communication on the Worldwide Web. So, you'll explore HTTP and URLs. Then you'll learn about SSL and TLS. Finally, you'll discover RDP and FTP. This course was originally created by Global Knowledge (GK).

Computer networking is an indispensable tool for single users and large enterprises alike, but unfortunately there are those who want to steal your information or profit off of you. Also, technology changes faster than most of us can keep up with it. In this course, you'll discover the elements of securing networks against attackers, including common security threats, malware, and social engineering. Then you'll learn about the risks of unsecured networks and how attackers compromise networks.
