Star and snowflake schemas are the most popular multidimensional data models used for a data warehouse. The crucial difference between Star schema and snowflake schema is that star schema does not use normalization whereas snowflake schema uses normalization to eliminate redundancy of data. Fact and dimension tables are essential requisites for creating schema. You can also refer our previously published article on the difference between fact and dimension table to understand it … [Read more...]
Difference Between Program and Process
A program and a process are related terms. The major difference between program and process is that program is a group of instructions to carry out a specified task whereas the process is a program in execution. While a process is an active entity, a program is considered to be a passive one. There exist a many-to-one relationship between process and program, which means one program can invoke multiple processes or in other words multiple processes can be a part of the same program.

Difference Between SRAM and DRAM
SRAM and DRAM are the modes of integrated-circuit RAM where SRAM uses transistors and latches in construction while DRAM uses capacitors and transistors. These can be differentiated in many ways, such as SRAM is comparatively faster than DRAM; hence SRAM is used for cache memory while DRAM is used for main memory. RAM (Random Access Memory) is a kind of memory which needs constant power to retain the data in it, once the power supply is disrupted the data will be lost, that's why it is known … [Read more...]
Difference Between RPC and RMI
RPC and RMI are the mechanisms which enable a client to invoke the procedure or method from the server through establishing communication between client and server. The common difference between RPC and RMI is that RPC only supports procedural programming whereas RMI supports object-oriented programming. Another major difference between the two is that the parameters passed to remote procedures call consist of ordinary data structures. On the other hand, the parameters passed to remote method … [Read more...]
Difference Between Concurrency and Parallelism
Concurrency and parallelism are related terms but not the same, and often misconceived as the similar terms. The crucial difference between concurrency and parallelism is that concurrency is about dealing with a lot of things at same time (gives the illusion of simultaneity) or handling concurrent events essentially hiding latency. On the contrary, parallelism is about doing a lot of things at the same time for increasing the speed. Parallelly executing processes must be concurrent unless … [Read more...]
Difference Between Digital Signature and Electronic Signature
A Digital signature is a kind of Electronic signature, but are distinct. Digital Signature is more secure and tamper-evident, which encrypt the document and permanently embed the information in it if a user tries to commit any changes in the document then the digital signature will be invalidated. On the other hand, an Electronic Signature is similar to digitalized handwritten signature verified with the signer's identity such as email, corporate ID's, phone PIN etcetera. Conventionally … [Read more...]
Difference Between DNS and DHCP
DNS and DHCP both work on the client-server architecture but are dissimilar terms. DNS maps the domain name to IP address whereas DHCP is a protocol which assigns IP to the hosts in a network be it statically or dynamically. DHCP is also used while setting up the DNS server to the host. Content: DNS Vs DHCP Comparison Chart Definition Key Differences Conclusion Comparison Chart Definition of DNS DNS (Domain Name System) is a mechanism which provides directory lookup … [Read more...]
Difference Between CAD and CAM
CAD (Computer Aided Drawing/Drafting) and CAM (Computer Aided Manufacturing) are computer technologies used for mainly product designing and manufacturing purposes where former is used in designing of the product through some designing software while latter involves software for controlling the machines in the industries such as CNC machines. CAD and CAM are the steps included in the manufacturing of a product. Let us understand the difference between CAD and CAM through the given comparison … [Read more...]
Difference Between CLI and GUI
User Interface is the term used for specifying how a user interacts with an electronic device, particularly computer. CLI and GUI are the different kinds of user interfaces. Mainly they differ in the graphics employed in the operating system. To perform an operation on the CLI system one has to write a command. On the other hand, in GUI users provided the visual aids (graphics) that include images and icons, which facilitates users to perform a task directly. CLI systems require expertise in … [Read more...]
Difference Between Web server and Application server
A server is a central repository where data and computer programs are stored and accessed by the clients in the network. Web server and Application server are types of the server where former is used to deliver web pages, and the latter deals with application operations performed between users and back-end business applications of the organization. A Web Server is a program that accepts requests for information and sends the required documents. An application server could be a program or a … [Read more...]
