Week 2: Introduction To Telecommunication
What is communication
Communication is simply the imparting, conveying or exchange of thoughts, messages, ideas, knowledge or information by sign and sound like speech, signals, writing, or behavior.
Diagram 1.1: The communication process
What is telecommunication
Telecommunication refers to communication over long distances, covers all forms of distance and conversion of the original communication, including radio, telegraphy, television, telephony, data communication and computer networking. It also can be define as process of transmitting or receiving information over a distance by any electrical or electromagnetic medium. The information may take the form of voice, video, or data.
Communications Technology Timeline:
Hardware
Hardware is the most obvious part of a computer-based information system. Hardware refers to the computers themselves, along with any and all peripherals, including servers, routers, monitors, printers and storage devices.
Software
Without softwa
the hardware wouldn't be very useful. Software is what tells the hardware how to function. It gathers, organizes and manipulates data and carries out instructions. Everything you do using a computer is done by the software.
Data
Data, or information is the information part of an information system, and whether that is statistical data, sets of instructions, lists of names or even graphics and animations
Procedures
It is commonly said that "procedures are to people what software is to hardware." Procedures are the rules, descriptions and instructions for how things are done. In computer-based information systems, procedures are frequently covered in instruction or user manuals that describe how to use the hardware, software and data.
People
People are the most often overlooked and most important part of a computer-based information system. It is people who design and operate the software, input the data, build the hardware and keep it running.
Communication
The components that allow one computer to communicate with another are hardware and are controlled by software. If communication between people is included in this element, though, it is an important element
WEEK 1:
what is communication??
The imparting,conveying or exchange of thoughts,messages,idea,knowledge or information by sign and sound like speech,writing or behavior.
how about telecommunication ??
Is refers to the transfer of data(communication)from a transmitter to a receiver across a distance
6 elements in computer&communication technology::
1.people
~ the most important element in communication because they built, analyse and develop the system.
2.procedure
~ specification of the series of actions, acts or operation which have to be executed in the same manner in order to obtain always the same result in the same circumstances example: emergency procedures.
3.data/information
~ information stored on the computer system, used by applications to accomplish tasks.
4.hardware
~ units for data:: Bit, Byte, Kilobyte(KB), Megabyte(MB), Gigabyte(GB), Terabyte(TB).
5.software
~ refers to parts of the computer that have no materials form: programs, data, protocols and others also called by software.
6.communication
~ transmission of data.
~ can conversion of data analog-to-digital, and digital-to-analog.
5 categories of ICT equipment/devices::
- input
-output
-process
-storage
-communication
