Lesson 1 Flashcards
(42 cards)
This refers to the process of conveying a message from sender to a receiver through a medium
Communication
It is the exchange of thoughts, messages, or information as by speech, signals, writing or behavior
Communication
This refers to the process of transmitting electronic information of any type including television pictures, sounds, facsimiles and data in the form of electronic signals or impulses
Telecommunication
These are the electronic transmission of signals for communications
Telephone
Radio
Television
It is the transfer of information from one computer top another over a communication link
Data Communication
This refers to the process of sending digital information from one device to another
Data Communications
This process is usually in binary form meaning the message is in the zeros and ones
Data Communications
It is an interconnection of usually passive electronic components that performs a specific function to simulate a transmission line or to perform a mathematical function such as integration or differentiation
Network
This is the construction, design, and use of network including the physical, the selection and use of telecommunication protocol, and computer software for using and managing the network and the establishment of operation policies and procedures related to the network for the purpose of sharing resources
Networking
What are the Benefits of Networking
- Resource Sharing
- High Reliability
- Efficiency
- Cost-Effectiveness
- Access to Powerful Communication Medium
This talks about the main goal of networking is to share resources, that is, to make all files or data, programs and equipment available to anyone in the network regardless of the physical location of the resources and user
Resource Sharing
This talks about Data loss, which can be prevented in networking by replicating data from one computer tp another or having a back-up.
High Reliability
High Reliability is also know as
Fault-Tolerance
This talks about networking is output-driven. it gives you the advantage of producing the maximum output in the quickest time possible.
Efficiency
This talks about having a network in a company also makes employees produce effective outputs with minimum time and efforts exerted
Efficiency
This is another benefit of networking, which is one of the main reasons why moist companies are into networking already. Imagine the money that a company can save upon having a network
Cost-Effectiveness
This is one of the amazing benefits that networking brought about is being able to communicate across the world anytime and almost anywhere. (As long as there is a means of connection to the biggest WAN ever existed, the internet).
Access to powerful communication medium
What are the three major types of network
- Local Area Network (LAN)
- Metropolitan Area Network (MAN)
- Wide Area Network (WAN)
This is a collection of two or more computers that are located within a limited distance of each other and that are connected to each other, directly or indirectly
Local Area Network
This is the basic building block of any computer networks
Local Area Network
This is a network with a maximum range of about 75 kilometers (45 miles) or so, and with high speed transmission capabilities
Metropolitan Area Network
Most of these include some type of telecommunications components and activity to handle long-distance transmissions.
Metropolitan Area Network
This is a network that connects users across large distances, often crossing the geographical boundaries of cities or states
Wide Area Network
These type of network has no geographical limit
Wide Area Network
