Answer:
The switch sends broadcast traffic to all ports like a hub to get the number of ports used and build its MAC address table.
Explanation:
A network switch is a device used in a LAN to connect all available workstations. Unlike a network hub, it is able to send frames from a host or workstation to another using its MAC address table.
An example of a switch is the Cisco 2950 switch. When it is first turned on, it acts as a hub, broadcasting traffic to all its ports. This process is used to create a MAC address table to get the IP address of workstations and the ports they relate to, enabling it to send unicast traffic to a specific port.
Answer:
The correct answer is: Bus Topology.
Explanation:
Bus Topology is a network setup where all the computers are connected to a single cable. Servers can connect easily to the network but it implies everyone connected has access to what everybody in the same network is doing. Security options are limited to no-existent under this topology.
In that case, if technicians cannot isolate a virus infection problem, it is the result of working with a bus topology where more than one computer is connected to the same network and every terminal has access to each terminal.
Answer:
Crisis-Mapping
Explanation:
Social networks are characterized by the immediacy of the content that users produce, and that same feature can be transferred to the online mapping of crises and conflicts.
Characteristics Crisis-Mapping:
- Real-time information processing.
- Immediacy;
- Visualization of the aggregated information can allow the detection of patterns that cause new analyzes to be undertaken or work hypothesis to verify.
- Continuity in the tasks, the maps record activity without interruption during the twenty-four hours of the day and seven days per week.
-
Flexibility in the protocols, since the tasks are distributed and evolve according to the dynamics (the crisis maps evolve with the crisis itself).
Answer:
Yes, Its a good idea but depends upon type of image. Like adding a logo to all the slides at top left corner is not just good but a must for all as well, when we are preparing official documents. However, other images when decided to be repeated must convey the correct intent in each page. If this is not the case, you need to avoid it. Intent is the most important aspect certainly. For rest see explanation.
Explanation:
Yes, and as mentioned above adding logo and other images meaningfully, and with correct intent is a good idea.
However, images must not be blurred, tiny or stretched. Also proper cropping is a must. The border should be solid as well. And when selecting a lot of images, the images must convey the correct meaning together. Moreover, the aspect ratio after stretching must be same as the original. You can do this in PowerPoint by going to format > crop > fill.
Ensure that watermarks are not revealed. Buy them rather than copy from somewhere for better outcome. And never amputate your readers with a headache creating backgrounds. You will loose readers then. The clip arts must be used in right number, and not a lot of them certainly.
Ensure both text and images are in correct ratios. Avoid using more than 2 images per slide.
They both need electricity. Both used in the kitchen.
