5 0

Answer:

A transmission line that consists of a tube of electrically conducting material surrounding a central conductor held in place by insulators and that is used to transmit telegraph, telephone, television, and Internet signals.

Coax, short for coaxial, is a type of cable used to transmit data, the internet, video and voice communications. A coax cable is made up of an aluminum and copper shield with an outer plastic jacket (see below) with the dielectric insulator helping to minimize signal loss.

When the tcp\ip translates a network layer address into a data link layer address (after not finding an entry for the network la
Pavel [41]
When the network stack translates an IP address (network address) to a MAC address (data link address) it sends a broadcast using ARP to all devices on the subnet asking who has the specified IP address.  The device with that IP address will then respond with it's MAC address to the ARP message's source.

With this in mind the answer to your question would either be broadcast or ARP request depending on what you have been learning in class.

Explanation:

Normally, regression testing are done on a manual basis by simply re-executing a subset of the entire available test cases or it can be done automatically by utilizing playback tools or automated capture. Hence, from the options, a combination of low-level components into clusters that perform a specific sub-function does not align with how regression testing are done either manually or automatically.

3. Describe what a pre-processor does in a network-based IDS tool such as Snort. Demonstrate your understanding of this function
MrRissso [65]

Answer:

Pre-processors look at organize traffic and screens parcel transmissions by examining andreassembling divided data.Frag2:preprocessor that battles against IP fracture attacks.Attackers sends a fragmentedTCP bundle with header data that gets entrance through a firewall.At the equivalent time,other parcels with vindictive information "slip" by the firewall undetected because of the fragmentationbeing so little by overwriting the header information.The frag2 pre-processor is specificallydesigned to break down bundle discontinuity to search out noxious information in the sections, which iswhy this pre-processor ought to never be turned off.Stream4:preprocessor Snort uses to coordinate assault marks over numerous packets.Anattacker endeavors to send different parcels into the system conveying parts of the attackpayload which are required to be reassembled by the host so as to start an attack.Stream4 stores the bits of the mark until all bundles are transmitted.Once they are alltransmitted, Stream4 finishes the signature and an alarm is created.
