The key difference between Inner Join and Natural Join is that Inner Join provides the result based on the matched data according to the equality condition specified in the query while Natural Join provides the result based on the column with the same name and same data type present in tables to be joined. DBMS […]
Difference Between Uniform and Nonuniform Quantization
The key difference between uniform and nonuniform quantization is that uniform quantization has equal step sizes while, in nonuniform quantization, the step sizes are not equal. Another important difference between uniform and nonuniform quantization is that, in the uniform quantization, some amount of quantization error can happen, but nonuniform quantization reduces the quantization error. Communication […]
Difference Between Mirroring and Replication
The key difference between mirroring and replication is that mirroring occurs on the database while replication occurs on the data and database objects. Another important difference between mirroring and replication is that mirroring does not support distributed environment but, replication supports distributed database environment. Mirroring and replication are two techniques in DBMS that improves data […]
Difference Between Synchronous and Asynchronous Learning
The key difference between synchronous and asynchronous learning is that synchronous learning is similar to a virtual classroom, involves a group of students engaged in learning at the same time while asynchronous learning involves student-centered learning similar to self-studying approach with necessary online learning resources. Today, online learning is a vital aspect of education. There […]
Difference Between grant and revoke
The key difference between grant and revoke is that grant gives a privilege to the user while revoke takes back the privilege granted to the user. SQL provides different authorization levels for users. Grant and revoke are two such commands. Grant command allows giving an authorization to a user while revoke command allows withdrawing the […]
Difference Between Synchronous and Asynchronous Transmission
The key difference between synchronous and asynchronous transmission is that synchronous transmission uses synchronized clocks to transmit data while asynchronous transmission uses flow control instead of using a synchronized clock to transmit data. Data transmission is the process of sending data from the transmitter to the receiver. There are two types of data transmission known […]
Difference Between Serial and Parallel Communication
The key difference between Serial and Parallel Communication is that in serial communication data transmission occurs bit by bit at a time while in parallel communication multiple bits transmit at a time. However, though the data is transmitted bit by bit, serial communication is fast for long distances and high frequencies. But, parallel communication is […]
Difference Between Fitbit and Apple Watch
The key difference between Fitbit and Apple Watch is that the Apple watch is more elegant in design and has more apps, but Fitbit watch is cost effective to purchase. Fitbit is a wearable device designed to compete with the Apple watch developed by Fitbit company while Apple watch is a smartwatch designed and developed […]
Difference Between Roku Express and Roku Streaming Stick
The key difference between Roku Express and Roku Streaming Stick is that Roku Express provides picture quality of 1080p HD on compatible TVs while Roku Streaming Stick provides a picture quality of 1080p HD, 4K Ultra HD and HDR on compatible TVs. Roku is a series of streaming players manufactured by Roku Inc. Roku streaming […]
Difference Between Bandwidth and Frequency
The key difference between bandwidth and frequency is that the bandwidth is the capacity of a communication link to transmit a maximum amount of data per second while the frequency is the number of oscillations of a signal per second. Bandwidth and frequency are two common terms in Networking and Telecommunication. This article discusses these […]
