Li-Fi vs Wi-Fi: A Battle of Light and Waves

Li-Fi vs Wi-Fi: A Battle of Light and Waves Li-fi is a light fidelity device that supports only the infrared and other lighting systems to transfer the data to the device which is used to receive from the sender device. Wifi is a wireless fidelity device that supports the radio waves to transfer the data to the wifi device which is used to receive the wifi signals at the limited ranges due to the device version capacity. Introduction to the computer system and computer applications related topics are listed following below here: Li-Fi vs Wi-Fi: A Battle of Light and Waves Let’s discuss the computer system related topic and questions above listed and their answers are following below here: Li-Fi vs Wi-Fi: A Battle of Light and Waves There are some points on the computer system and data communication related to the topic of “Li-Fi vs Wi-Fi: A Battle of Light and Waves” following below here: Lifi based data communication system:- Li-Fi is a light based signal data transmission ...

What do you mean by the specialization in the DBMS?

What is meant by the specialization in the DBMS model?

Specialization in the DBMS model

Specialization is the process to show the “entity set” have their “set of characteristics” which known as “sub classes” of the “type of entity” where the ‘type entity’ is called “super class” in the model of the “specialization” of “super-classes”.

Points to be remember in the specialization in the DBMS

  • In the specialization super class is a type of entity.
  • The characteristics of the entity are sub classes.
  • Set of sub classes of the entity of the superclass is a specialized model in the database model.
  • The set of the sub classes are also called special classes of the type entity which is super class in the specialization.
  • It is very different from or opposite from the generalization of the model.

Where the generalization is to show the similarities and the specialization is to show the differences of the entity sets in a both type of entity sets such as higher level entity sets and lower level entity sets.

Specialization is basically shows the differences among the higher level and lower level entity sets using with the characteristics of sets which means the sub-class of the type of entity that is super class in the specialization model.

The specialization is used to shows the sub classes are only to specific characteristics for the entity sets. Such as entity “A” is for “X” characteristics similarly the entity “B” for “Y” and “C” for “Z”.

What is meant by the specialization in the DBMS model?
In the typical model of special there are A, B and C entities following their characteristics are X, Y and Z. In the above model on the top appears is the super class which is the organization of the model.
Here is the tool of specialization below from the super class to shows the differences of the particular entity for specific attribute of the sub class.
Such as entity “A” is for “X” attribute or characteristic similarly “B” is for “Y” and “C” for “Z”. X, Y and Z are the characteristics to shows the specific properties of every entity or sub class.

Types of Local Storage in Computer Systems

Describe the different types of local storage of computer systems? The local storage device is a type of memory for the user to keep a database file for a long time to access again and stored as a distributed offline database on the local storage. The local storage device can be pendrive, compact discs, dvd, floppy drive, HDD, SSD, memory card etc. The local storage needs to keep the valuable database file for the user to provide the lost database if suddenly deleted or formatted the whole drive of the computer system. Local storage in computer systems refers to devices or media that store data directly connected to the computer. There are several types, including Hard Disk Drives (HDDs), which use spinning disks and magnetic heads to store data; Solid-State Drives (SSDs), which store data in flash memory, offering faster access times and lower power consumption; and Hybrid drives, which combine elements of both. Other forms of local storage include USB flash drives, SD cards, and CDs/...

Operating System Basics: Understanding How Your Computer Thinks

Operating System Basics: Understanding How Your Computer Thinks The operating system is a system software that provides the functionality of the hardware to use and operate it on the computer to get the output data or information for use depending on the users. The operating system supports the application software that provides another service on the computer system to give a solution from an application specific program. The operating system installed into the computer that stores all the database files into the storage device which is also used to access the memory location of files and information depends on the memory address. The operating system manages the resources of the computer that include the input resources, output resources, storage resources and other types of peripherals that are used to process the program of the operating system. An operating system (OS) is the core software that allows a computer to function by acting as a bridge between the user, applications, and...
