To begin with, let us learn about Wavelength Division Multiplexing (WDM).WDMWDM represents Wavelength Division Multiplexing. WDM is completed only in fibre optic channels. In WDM, there are several light waves from multiple sources are linked utilizing a prism to form a composite light signal sent across the channel.The application of WDM is the SONET network in which several optical fibre lines are multiplexed and demultiplexed. There is a new technique referred to as DWDM (dense WDDM). It can create multiple huge computers of the medium by composing mediums closer to one another. It achieves even higher efficiency.Types of WDMThere are ... Read More

Let us begin by learning about the Messaging Application Programming Interface (MAPI).MAPIMAPI represents Messaging Application Programming Interface. It is a messaging system that is used by Microsoft Outlook and Exchange for email, meetings, appointments, tasks, sticky notes, etc. It is based on a proprietary technology from Microsoft which uses an RPC-based connection to communicate with a MAPI-based mail server like Exchange.It includes a standard collection of C language functions that are saved in a program library which is referred to as a dynamic link library. It also supports the synchronization feature by which one can sync and view subfolders, custom ... Read More

Let us understand what supercomputers are.Super ComputersThe supercomputer is treated as the most dynamic computer in performance and processing. Supercomputers are adequate to solve immense numerical calculations, scientific problems and therefore it is known as number crunchers. They are complex to design and require teamwork research and development.Supercomputers are enhanced to implement only a small number of programs. This makes it possible for them to implement these few programs at a very high speed. Because of their inhibiting cost, they are used in high-end places such as in scientific research centers. The supercomputer involves thousands of processors, allowing it to ... Read More

Let us understand what encryption is.EncryptionEncryption can scramble the information so that only authorized persons can unscramble the conversation records. Encryption works by encoding the original information or plaintext with the support of sophisticated algorithms that change it to unreadable text or ciphertext.A decryption key would be required to revert to a readable structure. Encryption is best adapted for unstructured fields or databases that are not transformed regularly or saved in multiple systems. It can be used to protect sensitive information including payment card information (PCI), personally identifiable information (PII), financial account numbers, etc.Types of EncryptionThere are two types of ...

Let us begin by learning about cloud architecture.Cloud ArchitectureCloud Architecture is a combination of elements needed for a Cloud Computing service. A Cloud computing architecture includes multiple elements like a front-end platform, a back-end platform or servers, a network or internet service, and a cloud-based delivery service.Cloud computing allocates the file system that develops over multiple hard disks and machines. Data is not saved in one area only and in case one unit fails the other will take over necessarily. The user disk space is authorized on the distributed file system, while another important element is an algorithm for resource ... Read More

Let us understand what hashing is.HashingHashing is a numerical operation that modifies data into a specific number created from a string of text. The output is referred to as message digest or hash. It is possible to implement hashing on any element of data. The input data can have an arbitrary length but the output is always constant.In hashing, data goes through the hashing algorithm and supports a unique output but it is not possible to modify it back to the original information. A unique element of data will always make the same hash. Hashing is simpler to implement, but ... Read More

Let us understand what the solution architecture is.Solution ArchitectureSolution architecture (SA) is an architectural representation of a particular solution. Solution architecture associates direction from different enterprise architecture viewpoints (business, data, and technical), and enterprise solution architecture (ESA).A solutions architect is important for computing an organization’s business requirements and deciding how IT can provide those needs leveraging software, hardware, or infrastructure. Aligning the IT method with business goals has become superior, and a solutions architect can help regulate, develop, and execute technical solutions in support of business goals.A solutions architect also traverses communication between IT and business services. This architect is ... Read More

Let us understand what penetration testing is.Penetration TestingPenetration testing is a security which is applied where a cyber-security expert tries to discover and handle vulnerabilities in a computer system. Penetration testing is carried out to powerful an enterprise's security framework to defend its IT base from potential cyber-attacks.The tests work to identify any weakness, malicious content, errors, and vulnerabilities in the system. Penetration testing is an element of ethical hacking, where the main objective is to penetrate the data system.Penetration Testing is a legal, structured procedure to compute the security posture of an organization. This practice simulates an attack against ... Read More

Let us begin by understanding what DWDM is.DWDMDWDM represents Dense Wavelength Division Multiplexing. It is a technology in which several optical signals (laser light) of multiple wavelengths or colors are combined into one signal and are sent over the connecting channel to a lengthy area.When the optical signal transmission distance changes into thousands of kilometers, it results in loss of few signals. It can satisfy this signal loss, optical fibre amplifiers are used in the DWDM transmission system.The DWDM technology requires this gain bandwidth to send multiple optical signals together effectively. DWDM can address up to 80 channels (80 optical ... Read More

Let us begin by understanding what software security is.Software SecuritySoftware security is produced to protect and secure servers, computers, cellular devices, and networks from unauthorized access, intrusions, viruses, and several threats. Software security can defend information, users, systems, and organization from a broad range of risks.Software systems can be linked to stealing information, monitor content, enter vulnerabilities, and damage the behavior of the application. Malware can generate DOS (denial of service) or crash the framework itself. Buffer overflow, stack overflow, command injection, and SQL injections are the most common attacks on the software.Software security can represent the software that is ... Read More
