Understanding the Internet, intranets, and extranets
Understanding the Internet, intranets, and extranets

The next thing we want to discuss is Internet, Intranets, and Extranets. Internet The Internet is a worldwide publically accessible infrastructure of cables, routers, switches, and servers. One thing to keep in mind about the Internet is that the Internet is not the Worldwide Web. Many people will use Internet and Worldwide Web interchangeably, but […]

Understanding point-to-point and point-to-multipoint networks
Understanding point-to-point and point-to-multipoint networks

The final two topologies we’re going to look at are the Point-to-Point and the Point-to-Multipoint topologies. Point-to-Point topology In a Point-to-Point topology you basically have two different nodes that are connected directly to each other with no intervening device. This topology is commonly used to connect two different ends of a WAN connection. Alternatively, it […]

Understanding logical and physical network topologies
Understanding logical and physical network topologies

Logical and physical network topologies The first thing I’d like to talk about in networking are the topologies. As the name topologies implies, topologies have to do with the shape of a network. Topologies come in two types. They come in logical topology and physical topologies. Physical topology refers to the actual shape or layout […]

Understanding the HTTP and HTTPS communication
Understanding the HTTP and HTTPS communication

HTTP and HTTPS Today we are going to discuss two main communication protocol HTTP and HTTPS. we will take some basic concept about both. HTTP HTTPS HTTP Hypertext Transfer Protocol, or HTTP, is one of the most utilized protocols on the internet. HTTP traditionally runs on TCP port 80. The ports can be changed for […]

VoIP: SIP, MGCP, RTP, H.323

VoIP Voice over Internet Protocol (VoIP) is a method to carry voice traffic digitally over a network. Initial providers release services that emulate the traditional phone systems, changing out analog lines for digital. More recently, call services like Skype have started offering new alternatives.Session Initiation Protocol is a signaling and control protocol for communications. It is most commonly used for voice and video […]

Difference Between DNS and NetBIOS
Differnece between dns and netbios

DNS (Domain name system) The DNS Domain Name System is what translates your favorite domain names into IP addresses. It was first designed at the University of California Irvine in 1983. It is designed to be a hierarchical distributed system. It’s capable of translating the massive amounts of requests required by the internet or within a small private network. If a client wants […]

Difference between Packets and Frames
Packets and Frames

Frames is the last PDU used before information is put on the wire for transmission. Packets are formed of control information and the payload. When working with addressing and information flow, I tend to spend a significant amount of time in layers two and three, which are data link and network, respectively. Layer two refers to communication between devices on a common […]

Connection-oriented and Connectionless Protocols
Connection-oriented and Connectionless Protocols

TCP and UDP utilize the two connection types. Connection-oriented and connectionless. TCP is considered connection-oriented. This means it uses a system to provide reliable delivery of traffic. TCP utilizes a system known as the three way handshake to establish connections. Before a connection is considered established both hosts need to send and receive a send packet, and an ACK packet. Technically this could be […]

Understanding ARP (Address Resolution Protocol)
Understanding ARP (Address Resolution Protocol)

ARP (Address Resolution Protocol) The ARP command is a tremendous troubleshooting tool for ARP issues as well as layer two troubleshooting. ARP stands for Address Resolution Protocol and is responsible for doing the layer three IP mapping to layer two MAC addresses. Whenever a computer needs to send information to another host on a directly connected subnet, it will first check its […]
