When a customer purchases an item the EPOS system will track this and the data will be stored and keeps track of how much stock should now be in their store.

    Processor The processor more known as the CPU (Central Processing Unit) is a small chip; it is the main intelligence of the computer and controls everything that happens within the computer.

  8. Discuss potential barriers to effective communication in the workplace.

    Therefore, due to these issues it became more difficult to communicate effectively. Background Noise Background noise in the workplace became a large barrier of effective communication at BP.

Employees will be expected to complete tasks on their own without any help from others. Employees need to think for themselves and not rely on other people to tell them what they have to do next. At BP I showed independence by making meetings with people I needed specific information rather than waiting for someone to come to me.
