Let us understand what Wavelength Division Multiplexing (WDM) is.WDMWDM represents Wavelength Division Multiplexing. WDM is completed only in fibre optic channels. In WDM, various light waves from several sources are connected using a prism to form a composite light signal transmitted across the channel.The application of WDM is the SONET web in which various 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 two types of WDM, ... Read More

Let us begin by learning about Point to Point Link.Point to Point LinkPoint to Point topology is the easiest topology that links two nodes directly together with a common link. The whole bandwidth of the common link is constrained for transmission between those two nodes. The point-to-point connections use a real length of wire or cable to link the two ends, but other options, including satellite connection, or microwaves are also possible.In a point-to-point topology, two nodes in a network connect directly using a LAN cable or some other channel for data transmission. This is the easiest and economical option ... Read More

Let us begin by understanding what Synchronous Optical Networking (SONET) is.SONETSONET stands for Synchronous Optical Networking. It is a standardized digital connection protocol that can share a high volume of data over relatively long areas using a fibre optic medium. With SONET, there are various digital data streams are shared at the same time over optical fibre using LEDs and laser beams.SONET provides several streams concurrently and supports efficient services in telecommunication systems. It uses standardized line rates, therefore several types of organizations can be interconnected using SONET.The network architecture of a SONET depends on transmitting data even if a ... 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
