Answer 1

Blind or visually impaired clients: As a software developer I will develop a program for the blind or physically disabled clients such that during the running and execution of the code, the programs lines are read aloud by the system. There is another technology that can be combined with the program developed that is use of a screen reader. It is a basic piece of programming for a visually impaired or blind individuals (Lahav et al., 2015). A screen reader transmits whatever content is shown on the PC screen into a structure that the client can process. Most of the screen readers work by having a manufactured voice that peruses message so the visually disabled person might hear, others can also access the information by means of a refreshable braille script method. Such screen readers utilize crystals that can extend when presented to specific voltage levels enabling outwardly debilitated clients to utilize their fingers to peruse the content that is shown on the screen. However, while screen-reading programming can be reasonable, such equipment is generally costly.

Clients with limited or poor hand coordination: For the person with limited or poor hand coordination, can read the program and the data from the system. For scrolling the data over the screen and also for modifying the data the programmer can use a pointing device such as a mouse or a head stick and can control the computer and the programs by using the pointing device in case of poor hand coordination. Repositioning the mouse and the keyboards can also help the client with accessing the programs. Another method for accessing the program is through voice modulation where the client can access and modify the code through voice modulation attached to the system.

Answer 2

Three ways to reduce carbon footprint by using ICT and contribute to Green ICT are:

  1. Turning of the PC when not in use: A desktop computer with a CRT screen can expend a similar measure of power as 3 or 4 splendid lights on full time. Further, in the event if the systems are left on throughout the day, consistently, and are not designed to go into sleep/standby mode or to turn the screen off when not in dynamic use, power utilization can jump to as much as 245 kWh every month (Hilty et al., 2015).

  2. Manage the system Power Plan: Most PCs have power control feature that enable the clients to arrange power utilization on the system. Clients are permitted to pick settings when the system in a fully functional condition. There are many different types of options that are provided to the user such as, Power saving mode, while the computer is in active condition, Shutting the screen after a predefined time of idleness, Shutting the CPU after a predefined time of idleness and also activating rest/backup mode after determined period latency.

  3. Limiting options such as screensavers: Screensavers are a great approach to customize the PC but when the screensavers are in active mode, they can keep both the PC and screen dynamically active. And hence it consumes lot of power which leads to carbon footprints.

  1. This is a project as the PC is being based on creation lines of indistinguishable PCs and along these lines, it is a repetitive task. Here value is being made by rehashing and replicating a same device.

  2. This is additionally a project as comparable sort of houses has just been fabricated all over Australia. So there would be the accessibility of individuals who can do a similar construction work.

  3. It is a project as the redesigning is being made for the PC with the application to make it new, with further improvement of the capacity of the PC.

  4. It is project as it won't require any imaginative procedure rather it guarantees replication of framework for upgrading 120 PCs from Windows 7 to Windows 10.
