Define a system(3)
A system is a collection of parts working together for a common purpose. A system must produce an output but it needs to receive and process inputs in order to produce the outputs. Systems often interacts with other systems too
A system is a method of working together
Explain the difference between proprietary and open standards(2)
The difference between proprietary and open standards is proprietary standards are owned by a company and handle data in a certain way, communicate with the operating system in defined ways and work with a defined interface, where as, open standards are publicly available and can be modified by users
Proprietary standards are publicly available and can be edited by users where as open standards are owned by companies.
explain how the de facto standards have helped the development of easy to use computer systems(3)
De facto standards have helped the development by over complicating
De facto standards have helped the development of easy to use computer systems because they give you the basics that software needs to use. The microsoft word doc standard has become de facto standard for supplying word processed documents and all word processor programs needed to be able to write and read doc files
define the term embedded system
An embedded system is a computer system that forms part of an electronic device. Embedded systems control a certain part of a system
forms a computer
explain what the kernel of the operating system is (3)
The kernel of an operating system is the lowest level of an operating system which controls the hardware. They often support dedicated software applications.It reduces the effort needed to write software for the device because much of the functionality is taken from the operating system
It controls the highest part of an operating system. it is supported by other applications. It doesnt reduce effort needed to write software because functionality is not taken from the operating system
reason why it systems can fail to deliver what was intended.
the client can fail to mention situations the program needs to cover
The system might lack certain properties needed.
Briefly describe a computer system
A computer system is when you input something into a computer to get an output. Computer systems are based on processing data and producing information. They are electronic which makes them fast and the important thing about them is that they are programmable. This means that a computer system can be made to do many things depending on the instructions we give it
A computer system is where you get an output. they send out data that has already been processed and information that has already been produced. They are electronic so are slow and not important as they are not programmable so it cant do anything we ask it to do
