Answer:
Accessibility in the sense considered here refers to the design of products, devices, services, vehicles, or environments so as to be usable by people with disabilities. The concept of accessible design and practice of accessible development ensures both "direct access" (i.e. unassisted) and "indirect access" meaning compatibility with a person's assistive technology (for example, computer screen readers).
Accessibility can be viewed as the "ability to access" and benefit from some system or entity. The concept focuses on enabling access for people with disabilities, or enabling access through the use of assistive technology; however, research and development in accessibility brings benefits to everyone.
Accessibility is not to be confused with usability, which is the extent to which a product (such as a device, service, or environment) can be used by specified users to achieve specified goals with effectiveness, efficiency, convenience satisfaction in a specified context of use.
Accessibility is strongly related to universal design which is the process of creating products that are usable by people with the widest possible range of abilities, operating within the widest possible range of situations. This is about making things accessible to all people (whether they have a disability or not).Explanation:
Amost all professions include theuse of computers. Knowing a lot about them and the way they work could help you use them when needed in a work environment. It would also make an employer more likely to hire you.
To understand flow of programming logic flow chat technique been used. Once end user starts any learning programming flow chat design been learned and corrected the mistake. After success of flow chat design end user been advice to do programming and tested in computer.
<u>Explanation:</u>
In flow chart design is used for beginner level programming. Some time to make higher level managers to understand this flow chart design is used.
Flow chart has start, procedure, condition, function or procedure and end with stop diagrams.
Flow chart makes end user understand the flow of logics.
Suppose we need to do a process for a procedure, end user has to design with start flow chart symbol and put a procedure flow chart symbol with identification character, then end user has use same identification character and start designing the procedure in the flow chart diagram.
Procedure in flow char design is used to call same procedure number of time, so that repeated coding is avoided.
Answer:
The answer is Bootsrap
Explanation:
A bootstrap program which is also referred to as a bootstrap loader is a program that resides in the computer’s Read Only Memory. It starts the whole chain reaction and ends up with the entire OS being loaded. This program reads the computer’s hard drive boot sector and continues with the process of loading the Operating System. It first performs a POST test and then proceeds to load the OS intothe main memory.
