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.

3.1 Features of Information Systems An information system has 5 parts: Data Raw information The data input to the system must be accurate It should be stored in logical way such as pen drive and hard disk. People People are involved both in capturing the data and manage the information. Hardware Management information system (MIS) may run on just the sales and finance director's PC. It usually runs on a server, either shared or dedicated with Internet or intranet access for those who need it. Used for storing data. It is unusual to require specialized hardware. computer and server Software MIS can be built using standard software. manage the information in the computer. Telecommunications To connect with the use of internet. MIS are delivered across an intranet within a company's firewall for protection from competitors and others seeking this valuable management information. Used to protect and secure the data. 3.2 Functions of Information Systems ...

1. Keep the Software Up to Date Always keep the website to be up to date so that no hacker will not easily access onto the information from the web server. - Need to keep the website up to date so that to protect it from getting new threats. 2. Block SQL Injection SQL injection is an attack which vulnerable on bypassing the security of the website application. By inputting validation and limiting the queries can prevent the SQL injection attacks. - adding of codes to the database with a proper language 3. Prevent XSS Cross-site Scripting (XSS) will manipulate the vulnerable website into a malicious code for the user and when it is executed, the attacker can access and interact with the user's application. - Client-side - the attacker create a script or code to bypass the security of the application. 4. Providing Minimal Error Messages  Creating a least error messages for the website to be secured so that the information of the website will not be lost. such as Err...
