Virtual Reality is a growing technology.
VIRTUAL REALITY REFERS TO A HIGH-END USER INTERFACE THAT INVOLVES REAL-TIME SIMULATION AND INTERACTION THROUGH MULTIPLE CENSORIAL CHANNELS.
VIRTUAL REALITY IS A COMPUTER GENERATED WORLD WITH WHICH THE USER CAN INTERACT WITH THE COMPUTER GENERATED VIRTUAL WORLD.
IVAN SUTHERLAND IS THE 1ST PERSON TO DEVELOP A VIRTUAL REALITY MACHINE. THAT IS THE FIRST HEAD MOUNTED DISPLAY ( HMD ), WHICH WAS DEVELOPED IN 1968.

التعلم الجوال أو المتنقل هو نظام تعلم إلكتروني يقوم على أساس الاتصالات اللاسلكية بحيث يمكن للمتعلم الوصول للمواد التعليمية والندوات في أي وقت وأي مكان .
We discuss engineering and scientific computing in the Cloud. Users today have three major choices of computing: workstations, servers, and cloud. We compare benefits and challenges of each, and present a solution: the online UberCloud community, experiment, and marketplace for engineers and scientists to discover, try, and buy compute power on demand, in the cloud. Our approach of application containerization and tight software/hardware integration removes many of the known cloud roadblocks.

Cloud computing is a model for enabling ubiquitous, convenient,
on-demand network access to a shared pool of configurable
computing resources (e.g., networks, servers, storage, applications,
and services) that can be rapidly provisioned and released with
minimal management effort or service provider interaction.
雲端運算是⼀種模式,允許無處不在、便捷、依個體需求地使用網路存
取可調配的共享運算資源池(諸如網路、伺服器、儲存裝置、應用程式
與各類服務),可以在最少的管理作業或與服務供應商互動下,進行快
速配置和發佈資源

On-demand self-service (自助式隨需服務)
A consumer can unilaterally provision computing capabilities, such
as server time and network storage, as needed automatically
without requiring human interaction with each service provider.
用戶可以自行預備雲端的運算能力,例如服務器時間和網路儲存,適時
自動開啟,⽽無需與每⼀個服務提供者互動
線上加退選、春節訂票期間增加雲端的運算能力

Broad network access (廣泛網路接取)
Capabilities are available over the network and accessed through
standard mechanisms that promote use by heterogeneous thin or
thick client platforms (e.g., mobile phones, tablets, laptops, and
workstations).
功能是可在網路使用並透過標準的機制存取,促進各種簡約功能或完整
功能客戶端平台 (例如手機、平板電腦、筆記本電腦及工作站) 來使用

Resource pooling (共享資源池)
The provider's computing resources are pooled to serve multiple
consumers using a multi-tenant model, with different physical and
virtual resources dynamically assigned and reassigned according
to consumer demand. There is a sense of location independence in
that the customer generally has no control or knowledge over the
exact location of the provided resources but may be able to specify
location at a higher level of abstraction (e.g., country, state, or
datacenter). Examples of resources include storage, processing,
memory, and network bandwidth.
供應商的運算資源匯集在⼀起,以多租戶模式服務多個用戶,根據用戶
的需求,動態地分配和重新分配不同的實體及虛擬資源。這是⼀種與位
置無關的概念,用戶通常無法控制或知悉雲端資源的確切位置,但可能
是能夠指定在更高層次的抽象位置 (如國家、州、或數據中心)。資源包
括儲存空間、處理、記憶體、及網路頻寬。

Rapid elasticity (快速的彈性)
Capabilities can be elastically provisioned and released, in some
cases automatically, to scale rapidly outward and inward
commensurate with demand. To the consumer, the capabilities
available for provisioning often appear to be unlimited and can be
appropriated in any quantity at any time.
功能可以彈性地供應和釋放,在⼀些情況下,自動地,迅速放出及收回
使符合要求。對於用戶來說,可用於配置的功能往往是無限的,可以在
任何時間,調撥任何數量。

Measured service (可量測的服務)
Cloud systems automatically control and optimize resource use by
leveraging a metering capability at some level of abstraction
appropriate to the type of service (e.g., storage, processing,
bandwidth, and active user accounts). Resource usage can be
monitored, controlled, and reported, providing transparency for
both the provider and consumer of the utilized service.
雲端系統利用適用於服務類型的某種程度抽象化計量功能,自動地控制
及最佳化資源使用 (例如儲存空間、處理能力、頻寬、作用中的用戶)。
資源使用情形可以被監測、控制及描述,為供應商與用戶雙⽅提供透明
化地檢視這些所使用的服務。
