A computer system

A computer system is a piece of technology that takes in inputs, recognises their aims and then creates the correct output to suit that inputs needs. Just as when you press mechanical keys on a keyboard, the micro-chips on the inside of the keyboard receiver the pressure the user has put on the keys and then links it with that symbol, it then outputs that symbol to the main computer and is then recognised there. a system is recognised as having 3 major stages of function, these are:

all electronics have these, the input, process and output of a keyboard:

What Is Reliability?

If a computer is unreliable the effects could be fatal. This can vary from being catastrophic to annoying. reliability is making sure something functions without error. If an error occurred in an aeroplane system this could risk the lives of all the passengers on board, this is why everything has to checked for reliability and consistency.

Embedded systems

Embedded systems are systems designed to carry out specific functions within a larger system, this could range from simple dishwasher timings, microwave heats, to the many used to run a car.

Although the main key to a embedded system is it being dedicated to do one particular task.

Standards

Propriety systems are closed source systems which prefer their users to be restricted from modification, sharing, studying and redistributing.

de facto standards are when an invention from the public has came into power by the mass use from the public, for example the qwerty system made on early type writers and then later used on keyboards, this was because adjacent keys would get jammed due to the writers speed.

industry standard to be completed

Regulations

The Data Protection act was put in place to oversee organisations that accumulate and store data. The 1998 Data Protection act is needed because without it data can be misused. Identity theft is an example of data being misused.  the data protection act:

A person must give there consent for their data to be stored by an organisation.

Data must only be used for the reason it was intended for.

Only essential data should be collected.

All information collected should be accurate.

Information should only be held for as long as necessary.

The information stored should be kept secure.

Kernel

A kernel is the lowest level in an operating system. It controls the hardware. It manages the inputs and outputs of the operating system. It is also responsible for the management of the hardware like the memory. The kernel recognises the application software and then grants access to the hardware needed.

Input And Output

in the advancement of time comes the advancement of technology. and almost all technology has an input and output, this has revolutionised the country taking customisation to the next level. It starts at automatic data collection this is where sensors collect a signal though a large area of physical data. There is also business needs for the revolution of input and output, this has started with the RFID readers, Radio Frequency Identifications, this reads this metal plate that is usually stuck on to valuables in supermarkets, and the readers at the door identify them and set off an alarm. But as the times are more personalised they thought they would bring the manufacturing to the people, this is the 3D PRINTERS! with free software they allow people to design and produce their own cutsom made objects. from vases to fully working replicas of the assassins creeds franchise's hidden blade.
