The document discusses different types of virtualization including hardware, network, storage, memory, software, data, and desktop virtualization. Hardware virtualization includes full, para, and partial virtualization. Network virtualization includes internal and external virtualization. Storage virtualization includes block and file virtualization. Memory virtualization enhances performance through shared, distributed, or networked memory that acts as an extension of main memory. Software virtualization allows guest operating systems to run virtually. Data virtualization manipulates data without technical details. Desktop virtualization provides remote access to work from any location for flexibility and data security.

Types of Virtualization
Dr. Neeraj Kumar Pandey1

Types of Hardware virtualization
Dr. Neeraj Kumar Pandey3
Hardware virtualization is further subdivided into the following
types:
Full Virtualization – In it, the complete simulation of the
actual hardware takes place to allow software to run an
unmodified guest OS.
Para Virtualization – In this type of virtualization, software
unmodified runs in modified OS as a separate system.
Partial Virtualization – In this type of hardware
virtualization, the software may need modification to run.

Network Virtualization
Dr. Neeraj Kumar Pandey4
Internal Network Virtualization: It refers to the management and
monitoring of a computer network as a single managerial entity
from a single softwarebased administrator’s console. It is
intended to allow network optimization of data transfer rates,
scalability,reliability, flexibility, and security. It also automates
many network administrative tasks. Network virtualization is
specifically useful for networks experiencing a huge, rapid, and
unpredictable increase of usage.
External Network Virtualization: Combine many networks, or parts
of networks into a virtual unit. External Network Virtualization
involves and actual physical device that caters to your network.
This type of virtualization has been around for some time now, a
typical example of this would be a CISCO networking switch that
provides VLAN (virtual LAN) capabilities through its internal
CISCO iOS software.

Storage Virtualization
Dr. Neeraj Kumar Pandey5
In this type of virtualization, multiple network storage resources are
present as a single storage device for easier and more efficient
management of these resources. It provides various advantages as
follows:
Improved storage management in a heterogeneous IT environment
Easy updates, better availability
Reduced downtime
Better storage utilization
Automated management
In general, there are two types of storage virtualization:
Block virtualization It works before the file system exists. It
replaces controllers and takes over at the disk level.
File virtualization The server that uses the storage must have
software installed on it in order to enable filelevel usage.

Memory Virtualization
Dr. Neeraj Kumar Pandey6
It introduces a way to decouple memory from the server to
provide a shared, distributed or networked function. It enhances
performance by providing greater memory capacity without any
addition to the main memory. That’s why a portion of the disk
drive serves as an extension of the main memory.
Application level integration – Applications running on connected
computers directly connect to the memory
pool through an API or the file system.

Memory Virtualization…
Dr. Neeraj Kumar Pandey7
Operating System Level Integration – The operating system
first connects to the memory pool, and makes
that pooled memory available to applications.

Software Virtualization
Dr. Neeraj Kumar Pandey8
It provides the ability to the main computer to run and create
one or more virtual environments. It is used to enable a
complete computer system in order to allow a guest OS to
run. For instance letting Linux to run as a guest that is
natively running a Microsoft Windows OS (or vice versa,
running Windows as a guest on Linux)
Types:
Operating system
Application virtualization
Service virtualization

Data Virtualization
Dr. Neeraj Kumar Pandey9
Without any technical details, you can easily manipulate data
and know how it is formatted or where it is physically
located. It decreases the data errors and workload.

Desktop virtualization
Dr. Neeraj Kumar Pandey10
It provides the work convenience and security. As one can access
remotely, you are able to work from any location and on any
PC. It provides a lot of flexibility for employees to work from
home or on the go. It also protects confidential data from being
lost or stolen by keeping it safe on central servers.

Virtualization is a technique, which allows to share single physical instance of an application or resource among multiple organizations or tenants (customers).. Virtualization is a proved technology that makes it possible to run multiple operating system and applications on the same server at same time. Virtualization is the process of creating a logical(virtual) version of a server operating system, a storage device, or network services. The technology that work behind virtualization is known as a virtual machine monitor(VM), or virtual manager which separates compute environments from the actual physical infrastructure.

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.

Cloud architectures can be thought of in layers, with each layer providing services to the next. There are three main layers: virtualization of resources, services layer, and server management processes. Virtualization abstracts hardware and provides flexibility. The services layer provides OS and application services. Management processes support service delivery through image management, deployment, scheduling, reporting, etc. When providing compute and storage services, considerations include hardware selection, virtualization, failover/redundancy, and reporting. Network services require capacity planning, redundancy, and reporting.

On demand provisioningGOVERNMENT COLLEGE OF ENGINEERING,TIRUNELVELI

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.

Underlying principles of parallel and distributed computingGOVERNMENT COLLEGE OF ENGINEERING,TIRUNELVELI

Parallel and distributed computing allows problems to be broken into discrete parts that can be solved simultaneously. This approach utilizes multiple processors that work concurrently on different parts of the problem. There are several types of parallel architectures depending on how instructions and data are distributed across processors. Shared memory systems give all processors access to a common memory space while distributed memory assigns private memory to each processor requiring explicit data transfer. Large-scale systems may combine these approaches into hybrid designs. Distributed systems extend parallelism across a network and provide users with a single, integrated view of geographically dispersed resources and computers. Key challenges for distributed systems include transparency, scalability, fault tolerance and concurrency.

Delegates and events in C#Dr.Neeraj Kumar Pandey

This document discusses delegates and events in C#. It explains that a delegate is an object that can refer to a method. There are four steps to using delegates: declaration, defining delegate methods, instantiation, and invocation. Delegates can be singlecast or multicast. Events are declared using an event keyword and a delegate type, and allow an object to notify other objects when an event occurs. Multicast delegates can invoke multiple methods by adding delegate instances together using + operator and removing them using - operator.

Structure in c#Dr.Neeraj Kumar Pandey

Structures in C# are similar to classes but are value types stored on the stack. The document defines a Student struct with roll_number and Name properties, and shows how to declare a variable of the struct type, assign values to its properties, and copy one struct to another. Structs can also contain methods, as shown in the Rectangle struct example which defines a constructor, Area method, and Display method. Nested structs are also possible, like an Employee struct containing a nested Salary struct. The key differences between structs and classes are that structs are value types stored on the stack while classes are reference types.

cloud computing: Vm migrationDr.Neeraj Kumar Pandey

Virtual machine migration techniques can be categorized as non-live and live migration. Live migration has lower downtime and involves pre-copying memory pages to the destination host before migration, post-copying memory after migration, or a hybrid approach. Pre-copy migration creates duplicates during a warm-up phase before stopping the virtual machine to copy remaining changes, while post-copy sends pages on demand after migration completes and the virtual machine resumes.

Cloud Computing: VirtualizationDr.Neeraj Kumar Pandey

- Virtualization allows multiple operating systems to run concurrently on a single physical machine by presenting each virtual operating system with a virtual hardware environment. A hypervisor manages access to the physical hardware resources and isolates the virtual machines. - Cloud computing extends virtualization by allowing virtual servers and other resources to be dynamically provisioned on demand from large shared computing infrastructure. This improves flexibility and allows users to pay only for resources that are consumed. - The hypervisor software manages the virtual machines and allocates physical resources to each one while isolating them from each other. Example hypervisors include VMware, Xen, and KVM. Virtualization improves hardware utilization and makes infrastructure more flexible and cost-effective.

He believes AI agents aren't just tools—they're workers that take on repeatable tasks so your human team can focus on what matters. If you want to reduce time waste and increase output, AI agents are the next move.

AI Changes Everything – Talk at Cardiff Metropolitan University, 29th April 2...Alan Dix

Talk at the final event of Data Fusion Dynamics: A Collaborative UK-Saudi Initiative in Cybersecurity and Artificial Intelligence funded by the British Council UK-Saudi Challenge Fund 2024, Cardiff Metropolitan University, 29th April 2025 https://alandix.com/academic/talks/CMet2025-AI-Changes-Everything/ Is AI just another technology, or does it fundamentally change the way we live and think? Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater. At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts. At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.

cloud computing:Types of virtualization

1. Types of Virtualization Dr. Neeraj Kumar Pandey1

2. Major Types of Dr. Neeraj Kumar Pandey2

3. Types of Hardware virtualization Dr. Neeraj Kumar Pandey3 Hardware virtualization is further subdivided into the following types: Full Virtualization – In it, the complete simulation of the actual hardware takes place to allow software to run an unmodified guest OS. Para Virtualization – In this type of virtualization, software unmodified runs in modified OS as a separate system. Partial Virtualization – In this type of hardware virtualization, the software may need modification to run.

4. Network Virtualization Dr. Neeraj Kumar Pandey4 Internal Network Virtualization: It refers to the management and monitoring of a computer network as a single managerial entity from a single softwarebased administrator’s console. It is intended to allow network optimization of data transfer rates, scalability,reliability, flexibility, and security. It also automates many network administrative tasks. Network virtualization is specifically useful for networks experiencing a huge, rapid, and unpredictable increase of usage. External Network Virtualization: Combine many networks, or parts of networks into a virtual unit. External Network Virtualization involves and actual physical device that caters to your network. This type of virtualization has been around for some time now, a typical example of this would be a CISCO networking switch that provides VLAN (virtual LAN) capabilities through its internal CISCO iOS software.

5. Storage Virtualization Dr. Neeraj Kumar Pandey5 In this type of virtualization, multiple network storage resources are present as a single storage device for easier and more efficient management of these resources. It provides various advantages as follows: Improved storage management in a heterogeneous IT environment Easy updates, better availability Reduced downtime Better storage utilization Automated management In general, there are two types of storage virtualization: Block virtualization It works before the file system exists. It replaces controllers and takes over at the disk level. File virtualization The server that uses the storage must have software installed on it in order to enable filelevel usage.

6. Memory Virtualization Dr. Neeraj Kumar Pandey6 It introduces a way to decouple memory from the server to provide a shared, distributed or networked function. It enhances performance by providing greater memory capacity without any addition to the main memory. That’s why a portion of the disk drive serves as an extension of the main memory. Application level integration – Applications running on connected computers directly connect to the memory pool through an API or the file system.

7. Memory Virtualization… Dr. Neeraj Kumar Pandey7 Operating System Level Integration – The operating system first connects to the memory pool, and makes that pooled memory available to applications.

8. Software Virtualization Dr. Neeraj Kumar Pandey8 It provides the ability to the main computer to run and create one or more virtual environments. It is used to enable a complete computer system in order to allow a guest OS to run. For instance letting Linux to run as a guest that is natively running a Microsoft Windows OS (or vice versa, running Windows as a guest on Linux) Types: Operating system Application virtualization Service virtualization

9. Data Virtualization Dr. Neeraj Kumar Pandey9 Without any technical details, you can easily manipulate data and know how it is formatted or where it is physically located. It decreases the data errors and workload.

10. Desktop virtualization Dr. Neeraj Kumar Pandey10 It provides the work convenience and security. As one can access remotely, you are able to work from any location and on any PC. It provides a lot of flexibility for employees to work from home or on the go. It also protects confidential data from being lost or stolen by keeping it safe on central servers.
