- ICT stands for information and communications technology and is often used as an extended synonym for information technology (IT), but is a more specific term that stresses the role of unified communications[1] and the integration of telecommunications (telephone lines and wireless signals), computers as well as necessary enterprise software, middleware, storage, and audio-visual systems, which enable users to access, store, transmit, and manipulate information.[2] ( Wikipedia with modifications)
ICT skills for Business
General info about computing facilities in HH
- w:Windows 7 Enterprise and w:Microsoft Office 2013 are used pervasively in HH. Maybe even too so if one is a w:FOSS oriented engineering student at HH.
- HH has purchased licenses for nearly everything that MSFT sells. ( Check Mynet for more info ? )
- HH uses VDI w:desktop virtualization in its computers to bring an extremely available and responsive computing experience to thousands of users using the approximatelly 2000 computers there are in HH Pasila Campus.
- w:WinSCP(.net) is the tool of choice for Windows users moving files to network folders. ( Teacher ) Another option for Windows is the PScp available here ( jubo-jubo )
- Winscp allows you to access Myy-disk at home etc.
- If you are using OS X, Linux or FreeBSD at home you can use the pre-installed command line tool scp to get same functionality ( move files between machines securely ).
- The scp uses underlying ssh tool for security and encryption which can be used to securely connect to a shell on a server. ( jubo-jubo )
- If you are using OS X, Linux or FreeBSD at home you can use the pre-installed command line tool scp to get same functionality ( move files between machines securely ).
- Winscp allows you to access Myy-disk at home etc.

Excel
Microsoft Excel is a spreadsheet ( w:fi:taulukkolaskentaohjelma ), an interactive computer application program for organization and analysis of data in tabular form.
- Spreadsheets developed as computerized simulations of paper accounting worksheets.
- The program operates on data represented as cells of an array, organized in rows and columns. Each cell of the array is a model–view–controller element that can contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells.
- Excel features calculation, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications. ( Wikipedia on w:Microsoft Excel and w:spreadsheet mashed together )
- The program operates on data represented as cells of an array, organized in rows and columns. Each cell of the array is a model–view–controller element that can contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells.
- Spreadsheets developed as computerized simulations of paper accounting worksheets.
- w:Sum
- w:Maxima and minima
- w:Average
- w:If - ifexists
- Payment calculation

Cloud computing
- w:Cloud computing ( w:fi:Pilvilaskenta ) is a major pleasantifier of information technology systems acquisition and operation hassle and costs. Prices start as low as 15€ / VPS-from-cloud ( virtual private server ) with full root access.
- In cloud computing abstraction layers provide ability to move virtual servers around the cloud. It can anticipate breaking down of single physical components and move the services to a sound, functional piece of server hardware in advance to the physcial component breaking up.
- In addition to these fault surviving technologies cloud computing is very ecologically efficient as several, even tens of virtual servers can live on one physical machine instead of expensive server hardware sitting idly as the load is much lower then the total processing power by a factor of 10x or so. Think of a business buying a big physical server which is then utilized to 10% of it's maximum capacity whereas in cloud computing you can thanks to virtualization technologies have much better utilization rates for actual physical devices.

- w:Infrastructure as a service (IaaS)
- w:Platform as a service (PaaS)
- w:Software as a service (SaaS)
- w:Network as a service (NaaS)
- w:Storage as a service (STaaS)
- w:Security as a service (SECaaS)
- w:Data as a service (DaaS)
- w:Desktop as a service (DaaS - see above)
- Database as a service (DBaaS)
- w:Test environment as a service (TEaaS)
- w:API as a service (APIaaS)
- w:Backend as a service (BaaS)
- Integrated development environment as a service (IDEaaS)
- Integration platform as a service (IPaaS), see w:Cloud-based integration
In the w:business model using software as a service, users are provided access to application software and databases. The cloud providers manage the infrastructure and platforms on which the applications run. SaaS is sometimes referred to as “on-demand software” and is usually priced on a pay-per-use basis. SaaS providers generally price applications using a subscription fee. ( Wikipedia on w:Cloud computing )
