Answer: Please see below as the answer is self-explanatory
Explanation:
Repeaters, bridges and switches, route packets only within the limits of their own physical networks, using the physical hardware addresses of the different devices connected to the network.
On the contrary, routers are devices that interconnect physical networks, with one physical interface per each network to which the router is connected to.
Routers use logical addresses -called IP addresses in the TCP/IP suite, which operate at the network level, and take charge of the delivery of packets beyond the network that originated it, based on the IP address of the destination host.
Only when the IP destination address is within the same physical network as the router, it transforms the IP datagram in a Frame and sends it using the physical hardware address of the host.
Answer:
Option (d)
Explanation:
Option (a) the return type of the method specifies the type of the data that is returned for the method calling. The return type can be void if it doesn't return any value. The method return can be int, string and bool etc. So, option (a) is true and it not the correct option.
Option (b) is true it doesn't need any parameters. So, option (b) is not the correct option.
Option (c) is true. If the method has some return type other than void it must return something according to the return type.So, option (c) is not the correct option.
Option (d) is false. Getters and setters methods are used for accessing private variables but the name MUST start with get or set is false. The best practice is to start with get and set but it is NOT a must.
So, option (d) is correct option.
Disk access is way slower than
memory access. Caching is a technique to improve the disk access time. Block cache is a caching technique which
reduces disk accesses time. Here a
portion of disk is bought to cache for reading and a modified blocks are first
changed in cache but reflected in the disk at one go. On the other hand with write through caching
each modified block is written to cache and at the same time it is written to
the disk. Write- through caching
requires more disk I/O so they can have a negative effect on the performance.
Answer:
I want to take this time to discuss a few expectations and helpful information about how to participate in the weekly online discussions. You can scroll down the page or use the links here to navigate to each section. All Discussions can be found by clicking on the Discussions link located on the left-hand side of the course.
Explanation:
Participation in the discussion forums is critical for maximizing student learning in this course, both because your participation is graded and because it's a chance to engage in a dialogue about course material. In this course, students are required to be a part of an online community of learners who collectively interact, through discussion, to enhance and support the professional performance of each other. Part of the assessment criteria for the course includes evaluating the quality and quantity of your participation in the discussion forum.
The TAS will facilitate student discussions, although they likely will not address every single post. In most cases, they might share a related idea, intervene when the discussion goes off-track, or tie student comments together to help deepen student learning. Remember, if you have a specific question, pose
