FTP operates using a client-server model with different processes for control and data transfer between client and server computers.
On-demand computing refers to a delivery model where computing resources are made available to users as needed. These resources can be maintained within a user's enterprise or provided by a cloud service provider, in which case it is referred to as cloud computing. Effective use of cloud computing requires properly provisioning resources to avoid over-provisioning, which wastes money, and under-provisioning, which hurts performance. Efficient resource provisioning in the cloud is challenging due to the variety of VM types, pricing models, demand and cost uncertainties, and the need to balance multiple objectives like cost and quality of service.
Cloud computing is the on-demand delivery of IT resources and applications via the Internet with pay-as-you-go pricing. It evolved from earlier technologies like grid computing and utility computing by providing greater ease of use and on-demand scaling. A cloud broker acts as an intermediary between cloud service providers and customers, providing a unified interface and moving workloads between public and private clouds for improved performance and redundancy.
Implementation levels of virtualizationGokulnath S
Virtualization allows multiple virtual machines to run on the same physical machine. It improves resource sharing and utilization. Traditional computers run a single operating system tailored to the hardware, while virtualization allows different guest operating systems to run independently on the same hardware. Virtualization software creates an abstraction layer at different levels - instruction set architecture, hardware, operating system, library, and application levels. Virtual machines at the operating system level have low startup costs and can easily synchronize with the environment, but all virtual machines must use the same or similar guest operating system.

Client-server architecture separates programs into two parts - clients, which make requests, and servers, which fulfill requests. A client-server model has three main components: clients, servers, and communication middleware. Clients are front-end applications that users interact with to make requests. Servers are back-end applications that provide services to clients. Middleware facilitates communication between clients and servers. Common middleware standards are CORBA and COM/DCOM. Client-server systems can be organized as one-tier, two-tier, or three-tier architectures depending on how functionality is divided between clients and servers.

Client-server architecture separates programs into two parts - clients, which make requests, and servers, which fulfill requests. A client-server model has three main components: clients, servers, and communication middleware. Clients are front-end applications that users interact with to make requests. Servers are back-end applications that provide services to clients. Middleware facilitates communication between clients and servers. Common middleware standards are CORBA and COM/DCOM. Client-server systems can be organized as one-tier, two-tier, or three-tier architectures depending on how functionality is divided between clients and servers.
Virtualization allows multiple operating systems to run on a single machine by creating virtual versions of hardware resources. There are three main types of virtualization: partial, full, and para. A hypervisor manages virtual machines and allocates resources to guest operating systems. Cloud computing delivers computing as an on-demand utility over the internet by sharing resources. It provides software, platforms and infrastructure as services across public, private, hybrid and community clouds. Big data refers to massive volumes of structured and unstructured data that is difficult to process using traditional techniques and requires specialized infrastructure.
Network virtualization logically separates network resources and allows multiple virtual networks to operate over a shared physical infrastructure. It provides benefits like efficient usage of network resources, logical isolation of traffic between users, and accommodating dynamic server virtualization. Key enablers of network virtualization are cloud computing, server virtualization, software-defined networking (SDN), and network functions virtualization (NFV). A virtual tenant network (VTN) uses an underlay physical network and an overlay virtual network to logically isolate traffic for different users or groups. Common uses of network virtualization are in data centers and telecommunication networks.
Virtualization allows multiple operating systems and applications to run on a single hardware device by dividing the resources virtually. It provides isolation, encapsulation, and interposition. There are two types of hypervisors - Type 1 runs directly on hardware and Type 2 runs on an operating system. Virtualization can be applied to servers, desktops, applications, networks, and storage to improve utilization, security, and manageability.

Sri Guru Hargobind Ji - Bandi Chor Guru.pdfBalvir Singh
Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation w...IJCNCJournal
Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors
Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India
Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.
Keywords
Signal to Noise Ratio (SNR), Bit Error Rate (BER), mm-Wave, MIMO, NOMA, deep learning, optimization.
