The cloud computing works in a consolidated manner, and the big data comes under the cloud computing. The crucial difference between cloud computing and big data is that cloud computing is used to handle the huge storage capacity, (big data) through extending the computing and storage resources. On the other side, big data is nothing but an enormous amount of the unstructured, redundant and noisy data and information from which the useful knowledge have to be extracted. To perform the above … [Read more...]
Difference Between Firewall and Proxy Server
Both the Firewall and the Proxy server reside between the network and the local computer which provides the security against the network threats. The firewall and proxy server works in conjunction. Firewall functions at a lower level and can filter all types of IP packets while the proxy server deals with the application level traffic and filter the requests coming from the unknown client. A proxy server can be considered as a part of the firewall. A firewall basically prevents the access of … [Read more...]
Difference Between AM and FM
AM and FM are the modulation techniques. The prior difference between AM and FM is that in AM the frequency is kept constant and amplitude of the signal changes while in FM the amplitude of the signal is not allowed to change and frequency of the signal changes. Fundamentally, there are two types of continuous wave modulation/analog modulation, amplitude modulation and angle modulation. FM is categorized under angle modulation. Modulation is a method of changing some particular properties of … [Read more...]
Difference Between H.323 and SIP
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 Star and Ring Topology
A topology is a relationship exist between the links and linking devices (nodes) to each other which is represented by a geometric representation. Star and Ring topology are the types of network topologies. The crucial difference between star and ring topology is that the star topology is suitable for a primary-secondary type of connection whereas ring topology is more convenient for the peer-to-peer connection. The link is shared equally in the peer-to-peer connection. Inversely, in a … [Read more...]
