In asymmetric multiprocessing, all the processors are not identical and they follow a master-slave relationship; whereas in symmetric multiprocessing, all the processors are identical and they share the main memory. Read this tutorial to find out more about asymmetric and symmetric multiprocessing, and how they are different from each other. Let's start with a basic overview of asymmetric multiprocessing. What is Asymmetric Multiprocessing? Asymmetric multiprocessing is the use of two or more processors handled by one master processor. All CPUs are interconnected but are not self-scheduling. It is used to schedule specific tasks to a CPU based on priority and ... Read More

IPSec is a suite of protocols that provides security services during communications between networks. It supports network-level peer authentication, data origin authentication, data integrity, data encryption and decryption. It is often used to create a VPN.SSL is a networking protocol that provides a secure connection between a client and a server over the internet. It works at the transport layer. It is often used to secure the communication between a web browser and a web server.Read through this article to find out more about IPSec and SSL and how they are different from each other.What is IP Security (IPSec)?IPSec is ...

Bandwidth and Throughput are frequently used terms in telecommunications and sometimes we tend to use them as synonyms, but there's a subtle difference between these two terms.Bandwidth refers to the data capacity of a channel. It is defined as the total amount of data which can be transferred over a network in a specific period of time. Throughput, on the other hand, refers to the exact measurement of data transferred in a specific time period. It is also termed as "effective data rate" or "payload rate". Every network connection has a throughput, which explains how bits are transmitted across a ... Read More

Centralized Version ControlCentralized Version Control is a version control system using server/client model and server contains all the history of source code.Distributed Version ControlDistributed Version Control is a version control where each client can have same copy of source code as server has and both server and client maintain history of source code.Following are the important difference between Centralized Version Control and Distributed Version Control.Sr. No.KeyCentralized Version ControlDistributed Version Control1WorkingIn CVS, a client need to get local copy of source from server, do the changes and commit those changes to centeral source on server.In DVS, each client can have a ...

A workstation is a computer which is used to access LAN or Internet to get access to documents or perform a task, whereas a server is a software which responds to services requested by a client. Read through this article to know more about workstations and servers and how they are different from each other. What is a Server? A server is a computer, a device, or a program entirely responsible for managing network resources. Servers are called so because they provide the functionality to a "client, " another computer, device, or application. In theory, computers are considered servers ... Read More

The terms web browser and web server are very common in the field of computer science and Internet, however people often get confused between the two. The most basic difference between a web browser and a web server is that a web browser is an application software which is used to browse and display webpages available over the Internet, whereas a web server is a software hosted on a dedicated computer which provides these documents when requested by web browsers. Read through this article to know more about web browsers and web servers and how they are different from each ... Read More

Both RDBMS and HBase, both are database management systems. RDBMS uses tables to represent data and their relationships.
