Channel allocation techniques are used in radio resource management for wireless and cellular networks to distribute bandwidth and communication channels to base stations, access points, and terminal devices.The objective of channel allocation is to maximize system spectral efficiency in bits/s/Hz/site through frequency reuse while maintaining a high level of service by minimizing co-channel and neighboring channel interference among neighboring cells or networks that share the bandwidth.Channel allocation techniques can be grouped into two categories: Fixed Channel Allocation and Dynamic Channel Allocation.Read through this article to find out how these two channel allocation techniques are different from each other.What is Fixed ...

A Fact Table contains a combination of attributes from completely different dimension table. It helps the users understand and analyze the business dimensions that would help improve the business processes. Fact tables are also known as Reality tables.Dimension tables, on the other hand, help a Fact Table gather the dimensions on the data that needs to be collected.Read through this article to find out more about Fact tables and Dimension Tables and how they are different from each other.What is a Fact Table?In data warehousing, a Fact Table is one that contains the measurements, metrics, or facts of a business ...

Multimedia integrates different forms of content such as text, audio, video, graphics, etc., to form a single presentation. We come across so many different forms of multimedia element on almost every webpage or App that we open. Multimedia is definitely heavy than the traditional static text-based content, but any form of multimedia can immediately attract the users' attention and convey the message quickly.Hypermedia is a mix of hypertext with media such as graphics, sounds, and animations. It can be understood as the improved version of hypertext.Read through this article to find out more about Multimedia and Hypermedia and how they ... Read More
Both Client-Server and Peer-to-Peer networks transfer data from a source to a destination with minimal loss in transmission. Both these networks establish a communication channel through which data transmission takes place, however the channel remains dedicated in case of a Client-Server network, which is not the case with Peer-to-Peer networks.Read through this article to find out how client-server networks differ from peer-to-peer networks.What is a Client-Server Network?The client-server paradigm is a network process communication structure that connects service requestors, clients, and providers. A network or the Internet is used to connect the client and the server.The client-server approach, which also ... Read More
Communication, in general, is the process of transferring data from a source to a destination by using any of the available modes such as audio, video, text or even signals, etc. This communication may be straightforward between one sender and one receiver or it may include multiple senders and receivers. On the basis of the number of senders and receivers involved, a communication can either be "Point-to-Point" or "Multi-point".Read through this article to find out more about these two forms of communication and how they differ from each other.What is Point-to-Point Communication?In telecommunications, a point-to-point connection is a communications link ...

Both VPN and Proxy are used to connect to a remote system where one can access the host system from a remote location. However, VPNs are superior than Proxy servers because a VPN can protect your privacy and security by routing your traffic via a secure VPN server and encrypting it. A Proxy, on the other hand, just routes your traffic via a mediating server and it does not provide any additional security.Read through this article to find out more about VPN and Proxy and how they are different from each other.What is a Virtual Private Network (VPN)?A virtual private ...

Both Substitution Cipher and Transposition Cipher are traditional techniques used in cryptography to encrypt a plaintext into ciphertext in order to prevent it from getting tampered. Read through this article to find out more about Substitution cipher and Transposition cipher and how they are different from each other.What is Substitution Cipher Technique?In the Substitution Cipher technique, each character is substituted with other character/number or other symbol. This technique changes the identity of a character but not its position in the string.A substitution cipher encrypts a text sequence by replacing letters or units of text with other letters or units of ...

Data Compression refers to a technique that allows a large file to be reduced to a smaller-size. It also allows decompressing the compressed file back into its original form.Lossy compression restores the large file to its original form with some level of loss in data which can be considered negligible, while lossless compression restores the compressed file to its original form without any loss of data.Read through this article to find out more about Lossy and Lossless compression techniques and how they are different from each other.What is Lossy Compression?Lossy compression is a type of data encoding and compression that ...

Both MD5 and SHA1 are hashing algorithms. MD5 is simple and fast, but it does not provide good security. SHA1 is complex as compared to MD5 and it provides greater level of security.Read through this article to find out more about these two hashing algorithms and how they are different from each other.What is MD5?MD stands for Message Digest. MD5 is a hashing algorithm that produces a 128-bit hash value.Although MD5 was created with the intention of using it as a cryptographic hash function, it has been discovered to have several flaws. Yet, it is extensively used.MD5 can be used ... Read More
IPv4 and IPv6 are internet protocol versions, with IPv6 being an upgraded version of IPv4. There are several differences between the IPv4 and IPv6 protocols, including their functionality, but the most important difference is the quantity of addresses (Address space) that they create.Read through this article to find out more about IPv4 and IPv6 and how they are different from each other.What is Internet Protocol (IP)?The Internet Protocol is a set of rules that allows our computers to communicate via the Internet. IP addresses are basically in charge of directing the data packets to their correct destinations. IP controls all ... Read More
