Cloud computing and grid computing almost have the same vision of providing services to the users through sharing capabilities and resources. Although the terms are differentiated based on application focus, architecture, resource usage patterns, number of services, interoperability, business models etcetera. Cloud computing banish the need of buying the hardware and software which requires complex configuration and costly maintenance for building and deploying applications instead it … [Read more...]

ADSL and Cable Modems seem to be cost-effective methods for delivering broadband network services. The fundamental difference between ADSL modem and Cable modem is that ADSL modem uses twisted pair cables for providing both voice and data types of services. On the other hand, cable modems work on coaxial cable. Furthermore, the theoretical carrying capacity of the coaxial cable is hundreds of time higher than the twisted pair cable.

The GPS and DGPS are the satellite-based navigation systems. The basic difference between GPS and DGPS lies on their accuracy, DGPS is more accurate than GPS. DGPS was intentionally designed to reduce the signal degradation. GPS provides the accuracy about 10 meters, but DGPS can provide accuracy around 1 meter, even beyond that 10 cm. Content: GPS Vs DGPS Comparison Chart Definition Key Differences Conclusion Comparison Chart Definition of GPS Global Positioning … [Read more...]

The GPS and GPRS seem to be similar terms but are absolutely different in the sense. The difference between GPS and GPRS is that GPS is satellite-based navigation system whereas GPRS is used for providing cellular based data services. GPS facilitates a varying array of applications such as satellite operation, surveying and mapping, power grid, telecom, intelligent vehicles, precision agriculture etc. On the other hand, GPRS renders application such as Email accessing, multimedia messaging, … [Read more...]

ADSL (Asymmetric Digital Subscriber Line) and VDSL (Very High Bitrate Digital Subscriber Line) mainly differ in the speed of data transmission or data rate, where VDSL is significantly faster than ADSL. ADSL provides upstream rate 64 Kbps to 1 Mbps, and downstream rate 500 Kbps to 8Mbps whereas VDSL provides upstream rate 1.5 to 2.5 Mbps and downstream rate 50 to 55 Mbps. ADSL and VDSL are the variants of DSL technology. DSL stands for Digital Subscriber Line which basically transforms an … [Read more...]

Lossy compression and Lossless compression are the two terms widely categorised under data compression methods. The major difference between Lossy compression and Lossless compression is that lossy compression produces a close match of the data after decompression whereas lossless creates exact original data. Data Compression is a method of lessening the size of the data without significant loss of information. Content: Lossy Compression Vs Lossless Compression Comparison Chart … [Read more...]

A routing protocol describes the rules that must be followed by a router while it interacts with neighboring routers to learn the path and to maintain the network in the routing tables. The RIP and OSPF are the Interior Gateway Routing protocols which differ in many ways. The principal difference is that RIP falls in the category of distance vector routing protocol whereas OSPF is the example of link state routing. Another difference is that RIP uses bellman ford algorithm while OSPF uses … [Read more...]

The BOOTP and DHCP protocols are used for obtaining the IP address of the host along with the bootstrap information. The working of both protocols is different in some manner. DHCP protocol is the extended version of the BOOTP protocol. The major difference between BOOTP and DHCP is that BOOTP support static configuration of the IP addresses while DHCP supports dynamic configuration. It means that DHCP automatically assigns and obtain the IP addresses from the computer connected to the … [Read more...]

TDM (Time Division Multiplexing) and FDM (Frequency Division Multiplexing) are the two techniques of multiplexing. The common difference between TDM and FDM is that TDM share the timescale for the different signals; Whereas FDM shares the frequency scale for the different signals. Before understanding both terms in deep let's understand the term multiplexing. Multiplexing is a technique through which several signals are concurrently transmitted over a single data link. Multiplexed system … [Read more...]

Firewall and antivirus are the mechanisms to provide the security to our systems. Although the vulnerabilities are different in both cases. The major difference between Firewall and Antivirus is that a Firewall acts as a barrier for the incoming traffic to the system. Conversely, Antivirus protects against the internal attacks like malicious files etc. Both Firewall and Antivirus functions on different approaches like Firewall emphasizes on inspection of the data flowing from the internet to … [Read more...]
