Computer Networking Protocols and Standards
Video - Data Link Layer of OSI Networking Model
In this video by Kevin Wallace you learn about the Data Link Layer of the OSI networking model. More ... Video - The Upper Layers 5 Through 7 of the OSI Networking Model
In this video by Kevin Wallace you learn about Layers 5 Through 7 of the OSI networking model. More ... Dynamic Host Configuration Protocol (DHCP) Explained
In the early days of TCP/IP each device on a network had stored on its hard disk a
configuration file that an administrator used to manually assign a static IP address.
Today a network administrator is no longer required to maintain an IP and MAC address
configuration file a server. Every device on a network is automatically assigned a
unique IP address by Dynamic Host Configuration Protocol (DHCP). More ... NTP Server Systems - The Network Time Protocol
The Network Time Protocol (NTP) is utilized by NTP Server systems to distribute
accurate time information to network time clients. The NTP protocol is widely used
throughout the Internet to provide synchronization of computers and processes. This
article discusses how NTP server systems utilize the Network Time Protocol to
provide networks with an accurate reference of time. More ... TCP/IP Utilities
TCP/IP comes with a set of command line utilities that a network technician can use to
manage and troubleshoot a network. PING is used to test the ability of two hosts on a
network to communicate. More ... Protocol Suites
Network protocols define rules for handling data and communicating in a particular
networking environment. Individual protocols operate at specific layers in the OSI
reference model. A protocol suite is a group of protocols designed to work together. More ... Video - Network Layer (Layer 3) of OSI Networking Model
In this video by Kevin Wallace you learn about the Network Layer of the OSI networking model. More ... Wireless Standards - 802.11a 802.11b 802.11g 802.11n 802.11i Explained
The IEEE 802.11 family of standards which provides for Wireless Ethernet or (Wi-Fi) has
evolved over the years. This article explains the differences between 802.11a 802.11b
802.11g 802.11n and 802.11i. More ... The OSI Physical Layer
The Physical layer (OSI layer 1) deals with the mechanical and electrical specifications
of the network hardware. Layer 1 specifications define connectors, pin-outs, signal
voltages, and related software. More ... Network Switches
A bridge or router may be referred to as a "switch" because it uses information in the data
packet to choose a path from one network segment to another. A bridge may be referred to as
a "layer 2 switch" because it uses information from layer 2, the Data Link layer of the OSI model. More ... IP Addressing
The IP protocol uses a 32-bit address to define the network segment address and the node
address. If the device is to be connected to the Internet, the address needs to be unique
among all other devices connected
to the Internet. More ...
