How does satellite internet transmit data? While it’s easy to understand that an internet signal beams down from space into a satellite dish, providing us with access to high-speed satellite internet, it might be harder to understand what that signal is. The signal is, in fact, made of r...
TFTP can be used when the client and server do not need complex interactions, for example, online version uploads or upgrades on a lab local area network (LAN) in good conditions. TFTP consumes fewer memory resources than FTP. TFTP transmits data in plain text and does not provide...
A computer transmits data over a network in small chunks called packets, which consist of two parts: a header and a payload. The header contains identifying information such as the origin/destination hosts and basic protocol. The payload, on the other hand, is the actual application data that...
If a BPDU from a Layer 2 network does not carry any tag, run the port default vlan vlan-id and stp disable commands on the user-side interface of PE1. After the commands are executed, PE1 adds a specific tag to the received BPDU from a Layer 2 network and transpa...
1. Parse the URL When we enter a string of URLs, the browser needs to parse the URL, and then generate a request message sent to the Web server. Of course, this step is indifferent during our use, because the browser does this for us. Everything, we only care about the result of ...
Fiber internet transmits data as light signals through strands of glass or plastic fibers, which are bundled together in fiber-optic cables. Fiber-optic cables can carry data at much higher speeds and over longer distances than the traditional copper cables used in DSL or cable internet — and...
IoT gateways implement security measures such as data encryption and device authentication, often utilizing PKI for enhanced protection. The gateway then transmits the processed and secured data to the cloud over networks like Wi-Fi or Ethernet, maintaining efficient and secure data flow. Additionally...
An FC storage area network (SAN) transmits data without dropping packets and has traditionally supported higher bandwidths, but the FC technology is expensive and requires a specialized skill base to install and configure properly. An iSCSI SAN, on the other hand, could be implemented with ordina...
and transmits data via radio signals from the service provider’s facility to the customer’s location. Wireless helps provide long-range transmissions to areas that are remote and do not have access to DSL, cable, or fiber. The speed of wireless is similar to the speeds of DSL and cable...
How does HTTP work? Through the HTTP protocol, resources are exchanged between client devices -- specifically the web browsers used on the clients -- and web servers over the internet. The HTTP protocol makes it possible for client devices using browser applications to communicate with and downloa...
