6 Elements of Communication Technology & Computer Technology

1. People
• professional - who write the programs that computer use. e.g, programmer, computer engineer, etc.

• end user - including electronically preparing a client's taxes, an office worker using a word processing program to create a letter, a parent e-mailing his/her child's teacher, a person shopping on line, etc.  

      2. Procedure - is a clear specification for the sequence, timing, execution or a process.

      3. Data / information

• data - raw, unorganised facts.
• information - data that had been processed into a meaningful form.
• e.g, bit, byte, kilobyte (KB), megabyte (MB), etc.

     4. Hardware - physical parts of a computer.

                         - hardware component can be internal (located inside the main box/system unit of

                          computer) or external (located outside the system unit & connected to the system

                           unit via a wired / wireless connection)

                         - there are 5 categories computer operations which are input device,processing

                           devices, output devices, storage devices & communications devices.

      5. Software - the programs or instructions used to tell the computers use what to do.

                           - 2 types of software :

• system software - the program that allow a computer to operate a collectivity referred to.
• application software - consists of programs designed to allow people to perform specific tasks using a computer. e.g: playing games, watching videos, listening to musics, exchanging e-mail, etc.

      6. Communication / connectivity - the transmission of data from one device to another.
                                                            - such as, sending/retrieving data via the Internet,accessing
                                                               information located in a shared company database or
                                                               exchanging data/e-mail message with others.

THAT'S ALL .. HOPE YOU WILL ENJOY IT  :)
