green computingGreen computing, green IT or ICT Sustainability, refers to environmentally sustainable computing or IT. In the article Harnessing Green IT: Principles and Practices, San Murugesan defines the field of green computing as “the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems — efficiently and effectively with minimal or no impact on the environment.

Green computing, green IT or ICT Sustainability, refers to environmentally sustainable computing or IT. In the article Harnessing Green IT: Principles and Practices, San Murugesan defines the field of green computing as “the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems — efficiently and effectively with minimal or no impact on the environment.”The goals of green computing are similar to green chemistry; reduce the use of hazardous materials, maximize energy efficiency during the product’s lifetime, and promote the recyclability or biodegradability of defunct products and factory waste. Research continues into key areas such as making the use of computers as energy-efficient as possible, and designing algorithms and systems for efficiency-related computer technologies.

Green computing is the environmentally responsible use of computers and related resources. Such practices include the implementation of energy-efficient central processing units (CPUs), servers and peripherals as well as reduced resource consumption and proper disposal of electronic waste (e-waste). One of the earliest initiatives toward green computing in the United States was the voluntary labeling program known as Energy Star. It was conceived by the Environmental Protection Agency (EPA) in 1992 to promote energy efficiency in hardware of all kinds. The Energy Star label became a common sight, especially in notebook computers and displays. Similar programs have been adopted in Europe and Asia.

What is a thin client?

A thin client (sometimes also called a lean or slim client) is a computer or a computer program which depends heavily on some other computer (its server) to fulfill its traditional computational roles. This stands in contrast to the traditional fat client, a computer designed to take on these roles by itself. The exact roles assumed by the server may vary, from providing data persistence (for example, for diskless nodes) to actual information processing on the client’s behalf.

Green Computing

Thin clients occur as components of a broader computer infrastructure, where many clients share their computations with the same server. As such, thin client infrastructures can be viewed as the amortization of some computing service across several user-interfaces. This is desirable in contexts where individual fat clients have much more functionality or power than the infrastructure either requires or uses. This can be contrasted, for example, with grid computing.

Thin-client computing is also a way of easily maintaining computational services at a reduced total cost of ownership.
The most common type of modern thin client is a low-end computer terminal which concentrates solely on providing a graphical user interface to the end-user. The remaining functionality, in particular the operating system, is provided by the server.

Thin clients have their roots in multi-user systems, traditionally mainframes accessed by some sort of terminal computer. As computer graphics matured, these terminals transitioned from providing a command-line interface to a full graphical user interface, as is common on modern thin clients. The prototypical multiuser environment along these lines, UNIX, began to support fully graphical X terminals, i.e., devices running X server software, from about 1984. X terminals remained relatively popular even after the arrival of other thin clients in the mid-late 1990s. Modern UNIX derivatives like BSD and GNU/Linux continue the tradition of the multi-user, remote display/input session. Typically, X server software is not made available on thin clients; although no technical reason for this exclusion would prevent it.

Windows NT became capable of multi-user operations primarily through the efforts of Citrix Systems, which repackaged NT 3.5.1 as the multi-user operating system Win Frame in 1995. Microsoft licensed this technology back from Citrix and implemented it into Windows NT 4.0 Terminal Server Edition, under a project codenamed “Hydra”. Windows NT then became the basis of Windows 2000 and Windows XP. As of 2011 Microsoft Windows systems support graphical terminals via the Remote Desktop Services component.

The term thin client was coined in 1993 by Tim Negris, VP of Server Marketing at Oracle Corp., while working with company founder Larry Ellison on the launch of Oracle 7. At the time, Oracle wished to differentiate their server-oriented software from Microsoft’s desktop-oriented products. Ellison subsequently popularized Negris’s buzzword with frequent use in his speeches and interviews about Oracle products. Size comparison – traditional Desktop PC vs. Clientron U700

Client Simplicity:

Since the clients are made from low-cost hardware with few moving parts, they can operate in more hostile environments than conventional computers. However, they inevitably need a network connection to their server, which must be isolated from such hostile environments. Since thin clients are cheap, they offer a low risk of theft in general, and are easy to replace if stolen or broken. Since they do not have any complicated boot images, the problem of boot image control is centralized to the server.

On the other hand, to achieve this simplicity, thin clients sometimes lag behind thick clients (PC Desktops) in terms of extensibility. For example, if a local software utility or set of device drivers are needed in order to support a locally attached peripheral device (e.g. printer, scanner, biometric security device), the thin client operating system may lack the resources needed to fully integrate the needed dependencies. Modern thin clients attempt to address this limitation via port mapping or USB redirection software. However, these methods cannot address all use case scenarios for the vast number of peripheral types being put to use today.

Thin Clients has many advantages, so different people define thin clients in different way basing one of its advantage. Below are the few common definitions & sentences people often use to define thin client. Simply, Thin Client is nothing but a computer, but with very less configuration (specifications /capacity / power), still users can able to run all the latest Operating Systems and Applications (software), with the help of SERVER Computer which is connected to it through LAN Means, In Thin Clients you need not to install any OS or Applications, you have to install Only in SERVER where all thin clients are connected to it, all the OS and Applications will run on server and results are displayed in Thin Clients (user computers) Several users can run the same program simultaneously, but the program only needs to be loaded once with a central server. In Traditional PC, We have to Install OS and Applications Locally and use its Local Resources (CPU, Ram, HDD) for its Processing and Storing, where as in Thin Client you need not install any OS or Applications in Thin Client, but you can access OS and Applications from SERVER.

After graduating its 2020 class a month ago, MEST Africa, the Pan-African incubator, revealed that it will invest $100k each in seven start-ups.

In the final pitching event, fifteen teams participated, but only seven were picked, adding $700k to the overall funding round for this class.

In addition to the funding, start-ups can also participate in the ongoing incubation programme at MEST.

Ashwin Ravichandran, managing director of MEST Africa, had this to say, speaking about the range.

This was the first time that our entrepreneurs were educated online and away from our campus for the most part, and I’m proud to say they came out stronger than ever. We are incredibly excited about the 7 companies in which we have chosen to invest and look forward to continuing our support and mentorship as they start their companies across the continent.

The seven startups include:

Shopa, a last-mile ordering and delivery startup for informal retailers in Africa.

Heny, a forum to explore new flavors and perspectives for young professionals by changing the way diners eat.

Boxconn, a network that offers companies and individuals access to a list of confirmed distribution partners nearest to them, instantly delivers packages from one location to another.

KPILens, a start-up that automates the documentation, tracking and assessment process for development organizations and makes it simpler.

Tendo, an online network that ties independent resellers to companies, aims to tackle two of the biggest issues facing Africa: unemployment and gender inequality.

Joovlin, helps fintech platforms and merchants increase their sales by interconnecting mobile wallet users and allowing them to transact with each other.

Eleka, streamlines onboarding procedures for customers that are fraught with lengthy and expensive labor measures.

Move In Rentals, Credia, Uyolo, VendoorPro, Trastea, Cornerstock, Colibri, and JidiTrust are the other startups that didn’t receive funding from MEST.

Last year, MEST invested $100k in eleven startups while celebrating its 11th year in business. The sum, $1.1 million, represented the organization’s largest single cohort investment.

And although the amount this year is $400k smaller, the selected startups will have the opportunity to enter the incubator ‘s portfolio of over 40 startups across Ghana, Kenya, Nigeria, and South Africa.
