overlay

An overlay refers to a transparent or semi-transparent layer that is placed over an image or video.


In graphics and multimedia, overlays are commonly used to add special effects, annotations, or additional information to a base image or video.


Some common types of overlays include text boxes, shapes, images, and maps.


Overlays can be added using image editing software, video editing software, or through the use of specialized graphics libraries and APIs.


In some cases, overlays are used to provide a visual cue to the viewer, such as highlighting an important object or area in an image, while in other cases they may be used to obscure or censor parts of an image or video.

Entity-Relationship Diagram ERD in Data Base Management System (DBMS)

  An Entity-Relationship (ER) diagram is a visual representation of entities and their relationships in a database. Entities : Entities are the objects. They are usually represented by rectangles in an ER diagram. Each entity has attributes that describe its characteristics. Relationships : Relationships represent how entities are related to each other. They are typically depicted by lines connecting entities, with labels indicating the nature of the relationship. Relationships can be one-to-one, one-to-many, or many-to-many. Example : Let's consider a simple example of a library database: Entities of Library  Database : 1. Book : enity can include attributes like ISBN, title, author, and publication year. 2. Author : enity can include attributes like author ID, name. 3. Member : enity can include attributes like member ID, name, address, and contact information. Relationships : 1. Book-Author Relationship : Each book is authored by one or more authors, and an author ca...

Computer Network

Computer Network is essentially systems of interconnected computers and devices that communicate with each other for various purposes, such as sharing resources, exchanging data, or providing services. HUB Hub is a device that connects multiple devices in a network.  It operates at the physical layer of the OSI model and essentially broadcasts data to all devices connected to it.  Hubs are considered outdated technology and have been largely replaced by switches, which offer better performance and efficiency by only sending data to the intended recipient. ROUTER Router is a networking device that forwards data packets between computer networks.  It operates at the network layer of the OSI model and is responsible for determining the best path for data to travel from the source to the destination across interconnected networks.  Routers use routing tables and algorithms to make these decisions.  Additionally, routers often include features such as firewall pro...

mutable & immutable data types in python

In Python, mutable data types are those whose values can be changed, while immutable data types are those whose values cannot be changed after they are created. Mutable data types include lists, sets, and dictionaries, where their contents can be added, removed, or modified. Immutable data types include integers, floats, strings, tuples, and frozensets, where their values cannot be modified once they are created. Here are some examples of mutable and immutable data types in Python: Mutable Example: List: my_list = [1, 2, 3], my_list.append(4) Dictionary: my_dict = {'a': 1, 'b': 2}, my_dict['c'] = 3 Set: my_set = {1, 2, 3}, my_set.add(4) Immutable Example: Integer: my_int = 5 Float: my_float = 3.14 String: my_string = "Hello, world!" Tuple: my_tuple = (1, 2, 3) Property Mutable Objects Immutable Objects Definition Objects that can be modified after creation Objects that cannot be modified after creation Examples Lists, dictionaries, sets Numbers, string...
