DES (Data Encryption Standard) and AES (Advanced Encryption Standard) both are the symmetric block cipher. AES was introduced to overcome the drawback of DES. As DES has a smaller key size which makes it less secure to overcome this triple DES was introduced but it turns out to be slower. Hence, later AES was introduced by the National Institute of Standard and Technology. The basic difference between DES and AES is that in DES plaintext block is divided into two halves before the main … [Read more...]

In this article, we are going to discuss the two popular technologies that provide multiple accessibilities to a channel GSM and CDMA. The basic difference between GSM and CDMA is that GSM is specific to a SIM card that is used with the mobile phone. On the other hands, the CDMA is handset specific. Let us discuss some more differences between GSM and CDMA in the comparison chart shown below. Content: GSM Vs CDMA Comparison Chart Definition Key Differences … [Read more...]

1G and 2G are the two generations of mobile phones. 1G is the first generation of mobile phones that brought first wireless communication to us. 1G uses an analog signal for communications and use FDMA for channelization. 1G is used for voice communication, data transmission service was not provided by 1G. 2G was digitalization of 1G i.e. it uses the digital signal for communication. 2G uses TDMA and CDMA for dividing the channels, and it provides voice plus data communication services. Lets … [Read more...]

While communicating on an unsecured medium like the internet, you have to be careful about the confidentiality of the information you are sharing with other. The are two techniques use to preserve the confidentiality of your message, Symmetric and Asymmetric Encryption. The fundamental difference that distinguishes symmetric and asymmetric encryption is that symmetric encryption allows encryption and decryption of the message with the same key. On the other hand, asymmetric encryption uses … [Read more...]

Analog and Digital are the different forms of signals. Signals are used to carry information from one device to another. Analog signal is a continuous wave that keeps on changing over a time period. Digital signal is discrete in nature. The fundamental difference between analog and digital signal is that analog signal is represented by the sine waves whereas, the digital signal is represented by square waves. Lets us learn some more differences between analog and digital signal with the help … [Read more...]

Modem and router are the networking devices. Where a modem connects your computer or your network to the telephone line (Internet Service Provider) for accessing the internet. A router is meant for connecting different networks together. The basic difference between modem and router is that modem necessary for connecting your computer network to the internet whereas, a router is essential to direct the path to the traffic of data packets on the network. Let us study some more differences … [Read more...]

Circuit switching and packet switching are the two switching methods that are used to connect the multiple communicating devices with one another. Circuit Switching was particularly designed for voice communication and it was less suitable for data transmission. So, a better solution evolved for data transmission called Packet switching. The main difference between circuit switching and packet switching is that Circuit Switching is connection oriented whereas, Packet Switching is … [Read more...]

Router and switch both are the connecting devices in networking. A router is used to choose the smallest path for a packet to reach its destination. A switch stores the arrived packet, process it to determine its destination address and forwards the packet to a specific destination. The basic difference between a router and a switch is that a router connects different networks together whereas, a switch connect multiple devices together to create a network. Let us study some other differences … [Read more...]

MAC and IP are the addresses that uniquely defines a device and a connection in a network. A MAC address is a number assigned to the NIC card by the manufacturer. IP address is a number assigned to the connection in a network. The basic difference between MAC address and IP address is that a MAC address uniquely identifies a device that wants to take part in a network. On the other hand, an IP address uniquely defines a connection of a network with an interface of a device. Let us study some … [Read more...]

Cc and Bcc are fields that contains the list of the recipients of an email. The Cc field is used when we want a second party to have a record of an email that is sent to the primary recipient and let the primary recipients have knowledge of this. The Bcc field is used when we want a third party to keep the record of an email sent to primary recipients, the recipients of Cc without their knowledge. The basic difference between Cc and Bcc is that the recipients of Cc are visible to all, on the … [Read more...]
