Open loop and closed loop control systems are the two control systems. The open loop control system is one where the control action is independent of the output produced by the physical system. It means that the output of the open loop control system does not perform any changes to the control action. However, the closed loop control system is one where the control action depends on the output produced by the physical system. It means the output of the closed loop control system performs … [Read more...]
Private Key Vs Public Key
Private and public keys are two keys we use in the cryptosystem to secure information. In symmetric cryptography, we only use a private key that both communicating parties share. However, in asymmetric cryptography, each party has two keys, a public key accessible to all the other parties and a private key is only accessible by its owner. The asymmetric algorithm’s exact transformation depends on the public and private keys provided as input. What is a Key in Cryptography? Key plays a vital … [Read more...]
Flash Drive Vs Pen Drive
Flash drive and pen drive are memory modules developed using flash memory. Thus, they have similar capabilities and are fundamentally alike. Indeed, a pen drive is just one more form of a flash drive. But the fact is, a flash drive has uses that extend beyond those of pen drives. The flash drive is a larger flash memory module that is now a day rapidly replacing the hard disk drive. On the other hand, a pen drive is just a portable storage tool that uses a USB port to connect to the system. … [Read more...]
Difference Between Malware and Virus
People often use malware and virus interchangeably to indicate a malicious file in their system. Malware is a general term used to specify any malicious software present in the system, no matter how it affects your system or how it’s distributed. However, a virus is a specific kind of malware. When executed, a virus tries to replicate by attaching itself to the other executable files, eventually infecting them. People often confuse between the terms malware and virus because the first … [Read more...]
Difference Between Unit Testing and Integration Testing
Unit testing and integration testing are the test methods used to verify the smooth functioning of the software. As the name suggests, unit testing verifies each software unit, component or module in isolation. However, integration testing takes all the unit-tested components and integrates them to create a software architecture that dictates user-defined design. Let's first begin with what software testing actually is. What is Software Testing? Software testing is an association of … [Read more...]
4G Vs 5G
4G and 5G are cellular network technology. The technology is used to define mobile networks that allow wireless Internet access. The potential strength of any mobile network is that it connects the user even if he/she is travelling at a higher speed. How Mobile Network Works? Every mobile network has three functional components – Radio Access Network, Core Network and Transport Network. Radio Access Network – It is one to which your mobile phone connects. These are the towers installed … [Read more...]
Raster Vs Vector Images
Raster and vector are two file types we use to store digital images. The basic difference between these two types of digital images is that the raster image is formed using pixels. However, the vector image is formed using a mathematical expression, lines and curves with fixed checkpoints. Rescaling of raster images reduces the quality of the image. However, you can rescale the vector image infinitely without losing the quality of an image. The raster files are larger than the vector … [Read more...]
JPEG Vs TIFF
JPEG and TIFF are two common types of file formats that we use for storing images. JPEG and TIFF images are raster images defined using pixels with one or more associated numbers. The value of these numbers decides the location, colour, or size of the pixel in the particular image. Almost all the images you see on the web or captured using digital cameras are raster images. Being raster images, the image in JPEG format differs from the image in TIFF format in the way they compress … [Read more...]
RJ11 Vs RJ12
RJ11 and RJ12 connectors are standard registered jacks that people use to wire their telephone lines. Both of them use the same six-slot connector but differ in the wiring pattern and the number of wires they use. In RJ11, only four wires are terminated in the connector, whereas in RJ12, six wires are terminated in the connector. This section will identify all the differences between them. So let’s start with the comparison chart. Content: RJ11 Vs RJ12 Connectors Comparison Chart … [Read more...]
Intranet Vs Extranet
Intranet and extranet are derived from a global network that we refer to as the Internet. An intranet is a private network established inside an organisation to let all employees communicate and share resources. However, an extranet is a private network that authenticated users outside the organisation can access via a network password. The users inside the organisation only use the intranet. However, the users inside and the authorised users outside the organisation use the extranet. This … [Read more...]
