Let us begin by learning about Stream Control Transmission Protocol (SCTP).SCTPSCTP represents Stream Control Transmission Protocol. It is a new stable, message-oriented transport layer protocol. It is universally produced for Internet applications that have been introduced. These new applications include IUA (ISDN over IP), M2UA and M3UA (telephony signaling), H.248 (media gateway control), H.323 (IP telephony), and SIP (IP telephony), etc.SCTP connects the characteristics of UDP and TCP. SCTP is a stable message-oriented protocol. It protects the message boundaries, and simultaneously, detects hidden data, duplicate information, and out-of-order data. It also has congestion control and flow control architectures.The unit of ... Read More

To begin with, let us learn about the concept of bluetooth.BluetoothBluetooth is a proprietary open wireless technology which calculates for exchanging data over short locations (using short-wavelength radio channels in the ISM band from 2400-2480 MHz) from durable and mobile devices. It can generate personal area networks (PANs) with large levels of security. It was produced by telecoms vendor Ericsson in 1994, and it was initially accepted as a wireless approach to RS-232 data cables. It can connect multiple devices, overcoming problems of synchronization.Bluetooth is managed by the Bluetooth Special Interest Group, which has more than 14, 000 member organizations ... Read More

SDN stands for Software-defined networking. It is a network architectural model that enables programmatic administration, control, and optimization of network resources. The feature of the traditional network architecture model fails to combine the demands of current business IT.Organizations needed network infrastructure that enables the adaptability to scale and provide dynamic computing environments based on promptly growing technology and business landscapes.SDN produces a broad array of business benefits. Separation of the control and transport layers increases adaptability and stimulates time-to-market for new applications.The capacity to acknowledge more swiftly to problems and outages increase network availability and programmability creates it simpler for ...

Media Access Control (MAC) address is a physical address that works at the data link layer of the OSI model.A MAC address is a 48 or 64-bit address associated with a network adapter.MAC addresses are linked to the hardware of the network adapters, hence they are also known as the "hardware address" or "physical address."MAC addresses uniquely identify the adapter on the LAN.MAC addresses are expressed in hexadecimal notation. For example, "01-23-45-67-89-AB" in a 48-bit address or "01-23-45-67-89-AB-CD-EF" in a 64-bit address. Sometimes, colons (:) are used instead of dashes (-).MAC addresses are often considered permanent, but in some conditions, ... Read More

Firstly, let us understand what scareware is.ScarewareScareware 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 ... Read More

Let us understand what Adware is.AdwareAdware is a subgroup of spyware that can discover its method onto devices via affected websites through a wrongful installation. It generally includes a code that tracks web surfing habits and several non-public records. Adware passes user data onto a third party without the client consent or authorization.Adware’s motivation is to create income for its designer by serving promotions to web clients while they are surfing the web or during the underlying establishment process.The objectives of Adware is to create revenue by serving ads to web users while they are surfing the web or during ...

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
