[fusion_tabs design=”classic” layout=”horizontal” justified=”yes” backgroundcolor=”” inactivecolor=”” bordercolor=”” class=”” id=””][fusion_tab title=”Software” icon=””]Our schools use different software for operating desktops and laptops in offices, classrooms and computer labs. It is also incumbent on us to ensure we use the right software. Our understanding is that most of our schools use a Linux Operating system called Ubuntu for our desktops. This does not require a license to be used. On Ubuntu based desktops, you can use an open source software called Libre Office ( https://www.libreoffice.org ) This software provides the equivalent of MS Office products i.e. Excel, powerpoint, word etc. There are other open source products also available. Open source means you have the license to use the product without paying any license fee. These products are maintained and updated by a worldwide developer community and have the same functionality as licensed products but with out the finesse and some features.
In case your school is using Microsoft products, please remember that they require a license to be used. Microsoft Windows requires a basic license and an extended license depending on the version you use e.g. Windows 7, Windows 8.1 etc. License costs can vary and are in the range of Rs10, 000/- per license with out taxes. Microsoft office standard edition for education is available for aroundRs.3,500/- plus taxes. These licenses are called Paper Licenses and are issued to the school and are not device specific i.e. if a desktop is no longer used, it can be used in some other machine Do remember to buy these licenses from a Microsoft for education certified dealer. Office 365 is a cloud-based license, which requires an annual subscription and is not recommended for our schools
Lastly, some of you may be using Microsoft XP for office or teaching purposes. Please note that Microsoft XP is no longer supported and is vulnerable to attacks. In case, you have a machine with XP, please ensure internet connectivity is not available and wherever possible use is limited. For teaching purposes, use a projector from a single machine.
Do let us know if you need more information[/fusion_tab][fusion_tab title=”Hardware” icon=””]Every year our schools buy computer hardware from different vendors and quite often rely on trusted sources to help make a decision. Schools get a lot of acronyms such as Pentium, Dual core, i3, 3rd generation, GHZ etc. Although there is no simple way of making a decision, here are some guidelines, which could help
- Processors make: Intel or AMD are the two manufacturers, who produce microprocessors for desktop and laptop computers. Intel processors usually carry the prefix Pentium
- Processor type: Later day processors are more expensive. For school use, which is not intensive, one can make choices based on budgets available. Older processors will also get the job done.
- RAM or Random access memory, minimum recommended now is 4GB DDR3
- Hard disk: Normally hard disks for standalone machines will be 300 to 500GB.
- Monitors: Different types of monitors are available including the old bulky CRT monitors, LCD and LED monitors. 21.5 inch LED monitors are recommended and should be available for aroundRs.6,000/-
- Cabinet: Vertical cabinets occupy lesser space and come in slim and tower models.
- Keyboard and Mouse are standard accessories required. Webcam can be added if the desktop has Internet connectivity and can be used for calling.
Do remember to have the right chairs and table height for children.
These systems can run both Windows and Ubuntu when bought without software. Please ask your vendor to ensure that at least Ubuntu and Libre office is preinstalled.
Apple machines are expensive but come preinstalled with all operating systems and software.[/fusion_tab][fusion_tab title=”Projectors” icon=””]Some schools use projectors in teaching or media rooms. However, choice of projectors is getting increasingly complex and prices vary based on the choice. Here are some criteria to look at while choosing projectors:
Distance (from the screen)
- Long throw: 7 to 10 feet, usually suspended from the ceiling
- Short throw: 2.5 to 4 feet, can be wall mounted
- Ultra short throw: 1.5 feet, wall mounted
Advantage of wall-mounted projectors is that they are close to the screen and will not cast a shadow on the screen when the presenter comes in front of the light.
Lumens (light intensity )
- Minimum intensity is 2700 ANSI for classrooms. If your classrooms are getting a lot of sunlight, then they may require a higher intensity projector.
- Please check projector illumination at different times of the day to ensure that the visibility of good from all corners of the class
- Also check lamp life as communicated by the
Newer technology projectors come with HDMI (High definition multimedia interface). This interface carries audio, video and visuals on the same line and enables modern devices such as select tablets and mobiles to be connected to the projector.
Lastly, please choose an appropriate screen for the projectors. Screens can be fixed on the wall or can be drop down.
Hope this helps you in making the right choice of projectors.[/fusion_tab][/fusion_tabs]
