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...]

Block Cipher and Stream Cipher are the methods used for converting the plain text into cipher text directly and belong to the family of symmetric key ciphers. The major difference between a block cipher and a stream cipher is that the block cipher encrypts and decrypts a block of the text at a time. On the other hand, stream cipher encrypts and decrypts the text by taking the one byte of the text at a time. Content: Block Cipher Vs Stream Cipher Comparison Chart Definition Key … [Read more...]

Secure Socket Layer (SSL) and Transport Layer Security (TLS) are protocols designed to provide the security between the web server and web browser. However, there are minor differences between SSL and TLS, SSL is the foremost approach to serve the purpose and also it is supported by all browsers whereas TLS is the follow-on internet standard with some enhanced security and privacy features. Content: SSL Vs TLS Comparison Chart Definition Key Differences … [Read more...]

The main purpose of VPN and Proxy is to provide a connection between the host computer and the remote computer by hiding host computer's IP to make it secure against intruders. The basic difference between VPN and Proxy is that a Proxy server allows to hide, conceal and make your network id anonymous by hiding your IP address. It provides features like Firewall and network data filtering, network connection sharing and Data caching. This first became popular where some countries tried to … [Read more...]

To carry sensitive information, a system need be able to assure secrecy and privacy. A system cannot prevent unauthorized access to transmission media absolutely. Data tampering (an act of deliberately modifying the data through an unauthorised channel) is not a new issue, nor it is unique to computer era. Altering the information could possibly protect it from unauthorised access, and as a result, the only authorised receiver can understand it. The method used in such a way is called … [Read more...]
