Computer Networks

Network in other words, you can say is a ‘web’. So, Computer Network becomes ‘web of computers’. This special kind of web of computers should be designed so intelligently that there should be no mess, not much expensive, secure, efficient and quick in communicating with each other.

For computers to communicate with other computers there should be some devices which are able to send data (according to its nature) in medium. Network devices are the components used to connect computers or electronic devices to communicate in a network of computers.

“Network devices are those devices which are used to interconnect two or more than two computers with each other to share data, information, voice, resources and to communicate with each other.”

Network devices are the hardware responsible to send data on medium and some software, which helps in making a secure and efficient network. And the software is also used to monitor the traffic of the network device.

The network devices and its components which you use in a network depend on the type of need of the network with efficiency, speedy, secure and cheap. 

Double Link List

Double Link List 

The following C++ code will explains the implementation of Double Link List.

The following implementation is in object oriented using the DoubleLinkList class and dll object. The implemented ADT functions of Double Link List are insert, print, search, modify and delete.

Single Link List

Single Link List

The following C++ code will explains the implementation of Single Link List.

The following implementation is in object oriented using the SingleLinkList class and sll object. The implemented ADT functions of Single Link List are insert, print, search, modify and delete.

Insertion sort

In insertion sort, we compares adjacent elements and swap them, if they are out of order. We take the next element and insert into the sorted list that we maintained in the beginning of the array and repeats the procedure on it and so on.

Advantages: 

Insertion sort provides several advantages

• Insertion sort takes advantage of pre-sorting
• Simple implementation
• Efficient for small data sets
• Stable: does not change the relative order of elements with equal keys
• O(1) extra space
• O(n²) comparisons and swaps
• Adaptive: O(n) time when nearly sorted
• Very low overhead
• Online: New elements can be added during the sort

Merge Sort

Merge Sort 

The following C++ code will explains the implementation of Merge Sort and sort the user input numbers in descending order.

The following implementation is in object oriented using the MergeSort class and ms object. Actual logic of Merge sort is in the function of Merge().

Bubble Sort

Bubble Sort

The following C++ code will explains the implementation of Bubble sort and sort the user input numbers in descending order.
The following implementation is in object oriented using the BubbleSort class and bs object. Actual logic of Bubble sort is in the function of BSort(). 

Linear Searching

Linear Searching 

The following C++ code will explains the implementation of Linear Searching and sort the user input numbers in descending order.

The following implementation is in object oriented using the LinearSearching class and ls object. Actual logic of Linear Searching is in the function of LSearching().
Remember in Linear Searching, bubble sort is used to sort the data and to search in the sorted data Linear Searching is used.

General Searching

General Searching 

The following C++ code will explains the implementation of General Searching and sort the user input numbers in descending order.

The following implementation is in object oriented using the GeneralSearching class and gs object. Actual logic of General Searching is in the function of GSearching(). 
Remember in General Searching, bubble sort is used to sort the data and to search in the sorted data General Searching is used.

CMMI - Capability Maturity Model Integration

CMMI

CMMI (Capability Maturity Model Integration) is a set of rules and recommendations which should lead to improvements within your organization. It puts best practices used in software development and service management. It has been developed in Carnegie-Mellon University by the Software Engineering Institute (SEI).

CMMI may also be understood as a framework to recognize and improve processes within organization. Because of its abstraction it can be used for all kinds of manufacture. CMMI levels is a set of steps which each organization can obtain in order to increase its value on a market. It requires a lot of involvement and efforts to get onto level 5.

1. Initial
2. Managed
3. Defined
4. Quantitatively Managed
5. Optimizing

Pipeline Forwarding

What is pipelining?

Pipelining forwarding is a method to prevent the hazards of pipelining. If in a clock pulse multi-processes can be done, by availing this opportunity leads the processing and efficiency of our software can be increased as time consumption is much less.
