World of Computer Networking


World of Computer Networking is the name of a training course that includes everything you need to learn the Internet, including Ethernet, IP, Routing, Switching, TCP, UDP, NAT, DHCP and DNS, and prepares you for the CCNA exam. This course starts by talking about TCP/IP and OSI models, which is needed to understand the difference between hosts communicating with each other and all communication processes. In fact, TCP/IP is similar to the language that people speak and understand with each other. . In the next step, the physical layer includes bits and bytes, the Data Link layer includes Ethernet, MAC addressing and switching, the network layer includes Routing, IPv4, IPv6, subnetting, network masks, IP addressing, ARP ICMP, the transmission layer with the explanation of TCP protocols and UDP and their applications, as well as important protocols such as DHCP and DNS are discussed in the Application layer. Other discussions such as the difference between private and public IP addresses and the purpose of NAT are also discussed in this course.

What you learn in the World of Computer Networking course:

  • How computer networks work on different layers and what TCP/IP and the OSI model are
  • Logical and hardware addressing of devices (IP and MAC addresses)
  • IP addressing, Network masks, Subnets and Subnetting
  • How to apply switching selections by Switches and build MAC address table
  • How to make routing tables by routers and existing types of routers and how to use routing tables by routers to route packets
  • How to transfer end-to-end packets using switches, routers and how to change network headers (including Ethernet and IP) during the transfer process
  • Understanding the purpose and differences between TCP and UDP protocols
  • Understanding how to build a DNS registry and what types of DNS Nameservers exist and what their role is
  • Understand the difference between private and public IP addresses, their concerns, and the use of NAT
