Let us learn about scarewareScarewareScareware is a deceptive procedure created to trick Web users into downloading and purchasing malicious software (malware) by creating user interruption, uncertainty, or panic. Scareware formats involve malware, adware, spyware, Trojans, and viruses.Scareware creates pop-ups that look like Microsoft Windows system indications and alerts for anti-virus/anti-spyware applications, registry cleaners, or firewalls. These deceptive pop-ups make a user call to action to buy scareware and repair alleged bugs.Scareware can contain a clickjacking feature to redirect a client to an attacker’s website or initiate a malware download if a client attempts to close the pop-up. Scareware also compels ... Read More

Casting in computer networks means transmitting data (stream of packets) over a network. Following are the different types of casting used in networking −Unicast transmissionBroadcast transmissionMulticast transmissionUnicast Transmission (One-to-One)In Unicast transmission, the data is transferred from a single sender (or a single source host) to a single receiver (or a single destination host).The network switches hear the MAC addresses of the devices on the networks to which they are connected. They can then forward packets only onto those networks containing devices with the connected MAC addresses. Unicast gradually becomes less efficient as more receivers need to see identical data.ExampleIn the ... Read More

Wi-Fi stands for “Wireless Fidelity.” It can define Wireless LAN (WLAN) products that are based on the IEEE 802.11 standards. Wi-Fi work with both single carrier direct-sequence spread spectrum radio technology and multi-carrier OFDM (Orthogonal Frequency Division Multiplexing) radio technology.The next generation of the Wi-Fi standard is Wi-Fi 6. It is also referred to as 802.11ax. It is the newest step in a route of nonstop innovation. The standard constructs on the strengths of 802.11ac while inserting effectiveness, flexibility, and scalability that enables new and existing networks increased speed and space with next-generation applications.Wi-Fi authorizes products via a set of ...

Let us understand the concept of flutter.FlutterFlutter is a cross-platform UI toolkit that enables us to generate fast, magnificent, inherently compiled applications for mobile, net, and desktop using Dart programming languages. It develops the app with one programming language and an individual codebase. It is free and open-source. Google created it in May 2017 and is supervised by an ECMA standard. It is an increasing technology in popularity to pass superior native experiences.The main characteristic of Flutter is its quick and persistent response towards changing something. These changes can be associated with changes in code on hardware, emulators, and simulators. ... Read More

Let us begin by understanding the concept of checksum.ChecksumA checksum is a value that can verify the integrity of a document or a data transfer. Checksums are generally used to compare two sets of data to create sure they are equal.There are various common applications that contain verifying a disk image or testing the integrity of a downloaded file. If the checksums don't match those of the original documents, the data can have been changed or corrupted.A checksum can be calculated in several different ways, using different algorithms. For example, a basic checksum can simply be the multiple bytes in ... Read More

Firstly, let us learn about laptops.LaptopA laptop is a computer designed for flexibility. It is a lightweight computer that generally weighs 4-8 pounds (2 to 4 kilograms), based on display size, hardware, and multiple factors. A laptop computer is also called a notebook.Laptop computers can be modified into desktop computers. All peripheral devices including printers, scanners, and external drives are smoothly connected to the docking station so the laptop is only required to be plugged into the station and turned on.Even regular keyboards and displays can be used with a laptop with the right hardware and software configurations.Switching between a ...

Let us begin by learning about the internet.InternetThe Internet is the biggest network that connects millions of computers worldwide. It is a team of a network including public, private, government, universities, school, and other academic and business networks linked by several technologies including wireless, optical, and electronic.Internet usage is the calculation (defined in bytes, kilobytes, megabytes, or gigabytes) of the amount of data streaming through your computer and the Internet network for a specific time. These data are shared in both directions such as from the Internet network to your device (download), and from your device to the Internet network ... Read More

Let us begin by understanding what an IP Camera is.IP CameraIP camera is a network digital camera that need the Internet Protocol (IP) and has its IP address. An IP camera is used when defining video surveillance cameras.An IP camera uses an Ethernet cable and sends a digital signal. This type of camera can be simply networked and can send a signal to a network video recorder (NVR) placed on a local or remote network.IP cameras tend to capture better quality pictures, which is especially beneficial in the case of transferring targets, as frame rates can be adjusted according to ...

Let us understand what a hardware firewall is.Hardware FirewallHardware firewalls are frequently built within the base of broadband routers and are an essential part of a network setup, particularly on a broadband connection. A hardware firewall can be very adequate with minimal or no configuration and can guard each device on the local network. It facilitates packet filtering to test a packet’s header for source and destination analysis, which data is then compared with a group of pre-defined security rules.The packet will be forwarded if it meets the rules or is dropped. Although any user with some computer knowledge can ... Read More
