   • What are "Groovy" and "Grails" and what kinds of applications are built using them?

     Top Answer

     • What is Groovy on Grails?It doesn't exist under this name anymore. It's simply called Grails now.
     • What is Groovy?Originally, a dynamic language for the JVM. However, since Groovy 2.0, both static and dynamic typing are supported.
     • What is Grails?Grails (previously known as "Groovy on Grails") is a programming framework based on Groovy and inspired by Ruby on Rails (there are differences, but there are lots of similarities too). Like RoR, Grails promotes "coding by convention", development best practices, and is meant to be highly productive.
     • What kind of Applications are built using "Groovy on Grails"?Grails is used to build web applications that run on the JVM.
     • What are the advantages of Groovy on Grails?High productivity, focusing on business instead of plumbing. (Note that I wouldn't recommend to use Grails with an existing data model. The reason behind this is that Grails encourages a top-down approach where the databases ER model arises as result of the Domain classes. If you are using a legacy database, you cannot take this approach. You must map the database to the domain classes, and probably the naming convention won't match, making necessary the use of hbm.xml Hibernate configuration files or annotations. IMO, this is not a trivial change in the workflow, it can become really cumbersome and you end up losing most of the advantages of Grails.)
     • Why would one want to use Groovy on Grails when we have standard programming languages like C/C++, Java/J2EE, and .NET/C#?Because of point 5.

   • What are practical applications of Queues?

     Top Answer

     Answered Mar 06, 2010 · 18 votes

     Queues are used for any situation where you want to efficiently maintain a First-in-first out order on some entities. These situations arise literally in every type of software development.

     Imagine you have a web-site which serves files to thousands of users. You cannot service all requests, you can only handle say 100 at once. A fair policy would be first-come-first serve: serve 100 at a time in order of arrival. A Queue would definitely be the most appropriate data structure.

     Similarly in a multitasking operating system, the CPU cannot run all jobs at once, so jobs must be batched up and then scheduled according to some policy. Again, a queue might be a suitable option in this case.

     Stacks are used for the undo buttons in various softwares. The recent most changes are pushed into the stack. Even the back button on the browser works with the help of the stack where all the recently visited web pages are pushed into the stack.

     Queues are used in case of printers or uploading images. Where the first one to be entered is the first to be processed.

     Finding the median is a common application of such algorithm. E.g. I've used it in image processing for the median filter. Min, max, k-NN also use order statistic algorithms, so that's another application.

   • What are the applications of binary trees?

     Top Answer

     Answered Jun 27, 2021 · 498 votes

     To squabble about the performance of binary-trees is meaningless - they are not a data structure, but a family of data structures, all with different performance characteristics. While it is true that unbalanced binary trees perform much worse than self-balancing binary trees for searching, there are many binary trees (such as binary tries) for which "balancing" has no meaning.

     Applications of binary trees

     • Binary Search Tree - Used in many search applications where data is constantly entering/leaving, such as the map and set objects in many languages' libraries.
     • Binary Space Partition - Used in almost every 3D video game to determine what objects need to be rendered.
     • Binary Tries - Used in almost every high-bandwidth router for storing router-tables.
     • Hash Trees - Used in torrents and specialized image-signatures in which a hash needs to be verified, but the whole file is not available. Also used in blockchains for eg. Bitcoin.
     • Heaps - Used in implementing efficient priority-queues, which in turn are used for scheduling processes in many operating systems, Quality-of-Service in routers, and A* (path-finding algorithm used in AI applications, including robotics and video games). Also used in heap-sort.
     • Huffman Coding Tree (Chip Uni) - Used in compression algorithms, such as those used by the .jpeg and .mp3 file-formats.
     • GGM Trees - Used in cryptographic applications to generate a tree of pseudo-random numbers.
     • Syntax Tree - Constructed by compilers and (implicitly) calculators to parse expressions.
     • Treap - Randomized data structure used in wireless networking and memory allocation.
     • T-tree - Though most databases use some form of B-tree to store data on the drive, databases which keep all (most) their data in memory often use T-trees to do so.

     The reason that binary trees are used more often than n-ary trees for searching is that n-ary trees are more complex, but usually provide no real speed advantage.

     In a (balanced) binary tree with m nodes, moving from one level to the next requires one comparison, and there are log_2(m) levels, for a total of log_2(m) comparisons.

     In contrast, an n-ary tree will require log_2(n) comparisons (using a binary search) to move to the next level. Since there are log_n(m) total levels, the search will require log_2(n)*log_n(m) = log_2(m) comparisons total. So, though n-ary trees are more complex, they provide no advantage in terms of total comparisons necessary.

     (However, n-ary trees are still useful in niche-situations. The examples that come immediately to mind are quad-trees and other space-partitioning trees, where divisioning space using only two nodes per level would make the logic unnecessarily complex; and B-trees used in many databases, where the limiting factor is not how many comparisons are done at each level but how many nodes can be loaded from the hard-drive at once)

   • What are practical applications of weak linking?

     Top Answer

     Answered Mar 20, 2013 · 24 votes

     One use of weak linking is implementing the replaceable functions in the C++ standard. Namely:

     void *operator new(std::size_t);void *operator new(std::size_t, std::nothrow_t const &) noexcept;void *operator new[](std::size_t);void *operator new[](std::size_t, const std::nothrow_t&) noexcept;void operator delete(void *) noexcept;void operator delete(void *, std::nothrow_t const &) noexcept;void operator delete[](void *) noexcept;void operator delete[](void *, std::nothrow_t const &) noexcept;

     These are functions which must be provided by the implementation, but if a program implements them then the program's implementation replaces or overrides the implementation's version. This is easily implemented via weak linkage.

   • Overview
   • Building a network
   • Types of networks
   • Networking protocols

   The Internet is the world's largest computer network. Let's break that down:

   A computer network is any group of interconnected computing devices capable of sending or receiving data. A computing device isn't just a computer—it's any device that can run a program, such as a tablet, phone, or smart sensor.

   See full list on khanacademy.org

   The simplest computer network is two devices:

   A network like that only has to worry about a few things, like how to physically connect the two devices and how to send data over the physical connection in a format they both understand.

   Let's add one more device:

   Now there's additional complexity. How can each device know whether incoming data is meant for them or for their neighbor? This simple network will need an addressing scheme.

   Let's jump to six devices. There are actually many ways we can connect six devices together in a computer network:

   A diagram of 5 different network topologies for networks that each have 6 computing devices.

   See full list on khanacademy.org

   We use different terms to refer to networks based on their size and characteristics. Let's touch on a few of them here.

   The most common type of network is the Local area network (LAN), a network that covers a limited area like a house or school.

   The largest type of network is a Wide Area Network (WAN), a network that extends over a large geographic area and is composed of many, many LANs. Oftentimes, the networks in a WAN can only be connected by leasing telecommunications lines from different companies, since no single company owns all the infrastructure across the wide geographic area.

   Another type of network is the Data Center Network (DCN), a network used in data centers where data must be exchanged with very little delay.

   your understanding

   Based on those descriptions, what type of network is the Internet?

   See full list on khanacademy.org

   Whenever computing devices are connected together in a network, they need protocols to communicate with each other.

   If the devices want to communicate over the Internet, they must use the Internet networking protocols. There are many networks that aren't connected to the Internet that also use the Internet protocols, due to how well designed they are for networking.

   However, there are networks that use other protocols that are more suited for their task. Data center networks often opt to use networking protocols that take advantage of the incredibly closely knit architecture of the data center. That enables data centers to more efficiently run intensive algorithms, such as training a deep learning network.

   As we go forward in this unit, we will focus specifically on the Internet protocols that power the majority of computer networks. In the future, networks might be using protocols that haven't even been invented yet. Fortunately, the concepts underlying the Internet protocols are relevant to all networked systems.
