Answer:
Blocking Mode
Explanation:
Spanning Tree Protocol is used to allow path redundancy in the network without creating cycles/circles also called loops.
When two parts of the switched network are connected via two or more Layer 2 switches this result in a loop.
This affects the performance of the network as the result of broadcast packets flooding.
STP puts one port of the switch to forwarding mode and the rest of the ports within the same part of the network to the blocking mode to avoid broadcast packet flooding. STP puts all the ports that are allowing redundant paths to blocking mode and the one port that is left after this is placed in forward mode.
Spanning Tree Algorithm is used by STP to determine the optimal path of switch to the network.
Bridge Protocol Data Units are used to share the information about the optimal path determined by the spanning tree algorithm with other switches.
This information helps STP to eliminate the redundant paths.
So this is how STP allows only one active path to the destination while blocking all other paths to avoid switching loop.
Analytics can be used to determine the amount traffic a website is getting. The correct option among all the options that are given in the question is the second option.
Web analytics is used to determine several important
information’s about a website. This feature can also be used to determine the
region from which the maximum and the minimum traffic is arriving. Based on the
information’s received from analytics, the website owner can take steps to
improve the amount of traffic that is coming to the website.
Answer:b)Reserve Room, Enter Contact Information, Enter Reservation Detail
Explanation: The use case is described as actors , actors goal, usage of use cases, units of scope and initial point and terminating point of use cases .
The situation mentioned in the question will take place for the reservation of the room through the instances in the form like filling the contact details for the identification , filling out reservation information as well for getting the knowledge about the room requirement by the person.
These details help in reaching out the particular person if required, number of days he wants to book the room,any extra facility he would like to have etc. After these detail filling activity the room can be reserved successfully.Thus , the most appropriate option is option (b).
Other options are incorrect because room reservation cannot be done without any formality as mentioned in the question and entering contact detail and reservation detail one by one.
Answer:
When data is written to a WORM drive, physical marks are made on the media surface by a low-powered laser and since these marks are permanent, they cannot be erased. Rewritable, or erasable, optical disk drives followed, providing the same high capacities as those provided by WORM or CD-ROM devices.

Good luck
Answer:
132
Explanation:
We convert each number to base 10 (decimal) and multiply.
So 1011₂ = 1 × 2³ + 0 × 2² + 1 × 2¹ + 1 × 2⁰
= 1 × 8 + 0 × 4 + 1 × 2 + 1 × 1
= 8 + 0 + 2 + 1
= 11₁₀
1100₂ = 1 × 2³ + 1 × 2² + 0 × 2¹ + 0 × 2⁰
= 1 × 8 + 1 × 4 + 0 × 2 + 0 × 1
= 8 + 4 + 0 + 0
= 12₁₀
So, 1011₂ × 1100₂ = 11₁₀ × 12₁₀ = 132₁₀
So, the decimal equivalent of the product of 1011 and 1100 is 132
