Stack and Queue
Просмотров 1,1 тыс.3 месяца назад
Today, I will discuss two data structures: Stack and Queue. Stacks and queues are considered logical, conceptual, or abstract data structures because they organize and access data using specific rules. Their operations and efficiency are more about these rules than where the data is physically stored in the computer.

An intranet is a private network which is heavily protected by many different networking devices, such as router, firewall, proxy server, DMZ, honeynet, IPS and IDS. This diagram is an overly-simplified version of the reality. I try to put these devices together in a reasonable order, only for teaching and learning purpose.

    Awesome way to subnet. Really simplifies subnetting. ❤ However, I have the same question as @orcnewmymail. What would this table look like with less Network bits? And sacrificing an entire subnet is totally new to me.

    Sorry if this is a blonde question but in the real world - who choses what your original ID is? A lot of the case studies I see in textbooks start with "you've been given this network ID with this mask, generate n number of subnets." What I don't understand about all of this is, how does this original network ID get generated for a business or organisation, and how does it get passed down for you to work on? Second question - it looks like there is not a fixed limit for the number of hosts and subnets. The table in the last video stopped at 256, this one stops at 65536. Are there realworld practical limitations on the number of devices a business can include in a subnet? Thank you so much for your videos - you are my first ever RUclips subscribe because they are wonderful.
