MPLS Describe MPLS is stands for Multiprotocol label switching which is a mechanism used inside the computer network infrastructures to speed up the time it takes a data packet to flow from a node to another. Diagram How it works In MPLS , packets are directed through the network based on an assigned label with original IP routing in a packet- switched network, each data packet could determine its own path through the network. Examples Traffic engineering network management ATM Description ATM is a technique for packet switching that is used by telecommunication networks which they used asynchronous time-division multiplexing to encode data into small fixed sized cells. It is known as Asynchronous Transfer Mode. Diagram How it works The sender and receiver on a network creates a fixed channel between each other before sending the data and then the information will be sent in order. Example It is used in the campus backbone. References Tech...

What is network? Network topology is the arrangement of a network. Point-to-Point Topology Description Point-to-point topology are two devices directly connected to each other. Diagram Advantages Directly connected to each other so it is faster when sending messages. It is easy to set up the network. Disadvantages Only 2 host can connect to each other. Cannot send messages when one PC is broken. Bus Topology Description The devices are connected in one cable only. Diagram Advantages It is not expensive. It is easier to add another devices. Disadvantages If 1 device is broken in the cable, the other devices cannot send messages. There will be traffic if many hosts sent at a time. Star Topology Description One network device are connected to many hosts. Diagram Advantages There is no traffic. If 1 PC is not functioning, the others are not affected. Disadvantages It is expensive because network device a...

1.1 Types of Information 4 types of information: - Qualitative - Description - Description about the colors, textures, smells, taste and appearances. Quantitative - Numbers - Numerical information - Length, height, weight, speed, time, cost and ages. Primary - Data that you collected yourself - Real-time data -Sure about sources of data - Costly and time-consuming process - More flexible - Direct observation - Surveys - Interviews Secondary -  Data that you collected from external resources - Past data - Not sure about sources of data - Cheap and not time-consuming - Less flexible - The Internet - Televisions - Stories told verbally 1.2 Purpose of Information Operational Support - System - Data input is done by the end user - Processed to generate information products - User - Input data - System process - Output information - Monitoring and controlling its activities - A business can make immediate use of the information - Example of op...
