H.323 and SIP are specifically known for the IP signalling standards. The H.323 and SIP describe multimedia communication systems and protocols. These protocol suites differ in many ways. Essentially, H.323 is derived by ITU before the advent of SIP while SIP is acknowledged by IETF standard. IP telephony (Voice over IP) was evolved to implement cost savings, which actually produces from regulative taxes levied on long distances voice calls. This type of additional charge is not pertinent to … [Read more...]
Difference between LAN and VLAN
LAN (Local Area Network) is a collection of network devices which employ the communications between the connected devices. Similarly, VLAN (Virtual LAN) is a type of LAN which enhances the capabilities of a flat LAN. Now, how these can be differentiated? There are major differences between LAN and VLAN such as LAN work on single broadcast domain while VLAN works in a multiple broadcast domain. VLAN can combine the end station having similar requirement irrespective of their physical location … [Read more...]
Difference between PCM and DPCM
PCM and DPCM are the procedures used for transforming analog signal into digital. These methods are different as the PCM represents sample value by code words whereas in DPCM the original and sample values depend on previous samples. The conversion of analog-to-digital signal is beneficial for many applications because the digital signals are less susceptible to noise. The digital communication system provides better performance, reliability, security, efficiency and system integration. PCM … [Read more...]
Difference between Fast Ethernet and Gigabit Ethernet
An Ethernet is primarily a group of LAN technologies which are covered in IEEE 802.3 u standard. The ethernet is easily maintained and managed and considered to be low-cost network implementation solution. It comes in three variations, 10Base-T ethernet, fast ethernet and gigabit ethernet. The main difference between fast ethernet and gigabit ethernet is the contradicting speed where fast ethernet provides at maximum 100 Mbps of data transmission speed whereas gigabit ethernet offers high-speed … [Read more...]
Difference between Subnetting and Supernetting
Subnetting is the technique of partitioning a large network into smaller networks. On the other hand, the supernetting is the method used for combining the smaller ranges of addresses into larger space. Supernetting was devised to make the routing process more convenient. Additionally, it reduces the size of routing table information so that it could consume less space in the router's memory. The well-defined method for the subnetting is FLSM and VLSM while for supernetting CIDR is … [Read more...]
Difference between SAN and NAS
The SAN and NAS are the information storage techniques which are often mixed with one another because of alike acronyms. These can be differentiated by the fact that SAN (Storage Area Network) shares the storage to the dedicated network whereas NAS (Network Attached Storage) share the storage over a shared network. SAN uses block storage. Conversely, NAS uses the file system. These storage techniques were devised to fulfil the purpose of storing, protecting and managing the magnificent amount … [Read more...]
Difference between PHP and Python
PHP and Python are the popular high-level programming languages which have a strong open source background and also provide comprehensive design documentation. The major difference between PHP and Python is that PHP is broadly used for web development whereas Python is a general-purpose full-stack programming language. PHP is a server-side scripting language, in contrast, Python is an object-oriented scripting language. Content: PHP Vs Python Comparison Chart Definition Key … [Read more...]
Difference between Quick Sort and Merge Sort
The quick sort and merge sort algorithms are based on the divide and conquer algorithm which works in the quite similar way. The prior difference between the quick and merge sort is that in quick sort the pivot element is used for the sorting. On the other hand, merge sort does not use pivot element for performing the sorting. Both sorting techniques, quick sort and merge sort are built on the divide and conquer method in which the set of elements are parted and then combined after … [Read more...]
Difference between Object and Class in C++
The class is a technique used to bind data and its associated functions together, in contrast, Object is the created instance of a class. The object and class are the terms mainly used in object-oriented programming through which data is organized in the form of objects to reduce the code and application complexity. Objects change their state through the exposed methods and communicate with those methods. On the contrary, classes are passive and do not pass messages but used to create … [Read more...]
Difference between Friend Function and Friend Class
The Friend function and friend class are the techniques used to access the private members of a class by using friend keyword. The common difference between friend function and friend class is that when friend function is used the private class members can be accessed but in friend class, only the names of the friend class is accessed not the private members of the class. The friend feature whether used by function or class can produce a negative impact on the object-oriented framework as it … [Read more...]
