  • Object Oriented Analysis and Design using CRC Cards
  • A CRC cards is an index card that is use to represent the responsibilities of classes and the interaction between the classes. CRC cards are an informal approach to object oriented modeling. The cards are created through scenarios, based on the system requirements, that model the behavior of the system. The name CRC comes from Class, Responsibilities, and Collaborators which the creators found to be the essential dimensions of object oriented modeling.

      One of the most popular methods for identifying and categorizing classes is to use class-responsibility-collaboration cards (CRC). Each CRC card represents a single class's data attributes, responsibilities, and collaborations. source : Thought Process Book..

      You need to create three sections on each card: - The name of the class - The responsibilities of the class - The collaborations of the class
  • Why uses CRC cards?
  • ...4 more annotations...
  • They are portable... No computers are required so they can be used anywhere. Even away from the office. The allow the participants to experience first hand how the system will work. No computer tool can replace the interaction that happens by physically picking up the cards and playing the roll of that object... The are a useful tool for teaching people the object-oriented paradigm. They can be used as a methodology them selves or as a front end to a more formal methodology such as Booch, Wirfs-Brock, Jacobson, etc.

What is Domain Name Resolution - 0 views

  • What is Domain Name Resolution Introduction When using the Internet most people connect to web sites, ftp servers or other Internet servers by connecting to a domain name, as in www.bleepingcomputer.com. Internet applications, though, do not communicate via domain names, but rather using IP addresses, such as 192.168.1.1. Therefore when you type a domain name in your program that you wish to connect to, your application must first convert it to an IP address that it will use to connect to. The way these hostnames are resolved to their mapped IP address is called Domain Name Resolution. On almost all operating systems whether they be Apple, Linux, Unix, Netware, or Windows the majority of resolutions from domain names to IP addresses are done through a procedure called DNS.

      Yes .....we know that Web sites are on servers that has IP adresses like this 217.143.56.12 for example .....this article tell us how the site name [www.google.com] is converted to the IP thanks Mans

  • Hosts File - There is a file called the HOSTS file that you can use to convert domain names to IP addresses. Entries in the HOSTS file override any mappings that would be resolved via a DNS server
    • Islam TeCNo
      Islam TeCNo on 08 Jun 09
       
      I think this is what some spam and adware programs use .... you type a normal site Name but you go yo another site ... i think so !!
  • Netbios - This only applies to Windows machines and will only be used to map names to IP addresses if all previous methods failed. This method will attempt to map the netbios name you are trying to connect to with an IP address.

    What is Process Control Block ? Today in this Computer Science Study Material for Gate we will discuss about process control block and its various field which provides the information about process. .So let see what is process control block. A Process Control Block is a data structure maintained by the Operating System for every process. Each process has it own data structure. When a process is created then a unique id is assigned to the process Operating system identify a process among all processes on the basis of this process id. A PCB keeps all the information needed to keep track of a process. Generally a process control block contains the following information about a process.

      In graph theory, breadth-first search (BFS) is a graph search algorithm that begins at the root node and explores all the neighboring nodes. Then for each of those nearest nodes, it explores their unexplored neighbor nodes, and so on, until it finds the goal. ya3ney be el 3arby keda lw ana 3ndy tree maslan we el tree dh bettkwen mn shwit levels 3ady gedan.. lama hagey 23mel search 3la node mo3ina fi el tree deh hamsk el tree mn el root bet3ha ely hwa level 0 we habda2 2mshy level by level y3ney hanzl 3la el level 1 we hakaz le 3'it mal2y el node bet3ty ,,,, see this ,, it's a tutorial show how BFS algorithm is work!! http://www.personal.kent.edu/~rmuhamma/Algorithms/MyAlgorithms/GraphAlgor/breadthSearch.htm
  • Memorize the value of pi You should always try to remember the value of pi as far as possible, 3.1415926535897932384626433832795, certainly the part in italics. The judges may not give the value in the question, and if you use values like 22/7 or 3.1416 or 3.142857, then it is very likely that some of the critical judge inputs will cause you to get the wrong answer. You can also get the value of pi as a compiler-defined constant or from the following code: Pi=2*acos(0)

  • You cannot always check the equality of floating point numbers with the = = operator in C/C++. Logically their values may be same, but due to precision limit and rounding errors they may differ by some small amount and may be incorrectly deemed unequal by your program
