Protein Data Bank (PDB)

What is Protein Data Bank???

It is a repository for the three-dimensional structural data of large biological molecules, such as proteins and nucleic acids.

The data can be obtained by X-ray crystallography or NMR spectroscopy.

 PDB is a key resource in areas of structural biology, such as structural genomics. Now, scientists are required to submit their structure data to the PDB.

This data can be accessed on the Internet via the website RCSB. The data here is sent by the biologists and biochemists from around the worlds.

By accessing this website, students and researchers can understand all aspects of biomedicine and agriculture, from protein synthesis to health and disease. 


The RCSB PDB builds upon the data by creating tools and resources for research and education in molecular biology, structural biology, computational biology, and beyond.

Use this website to access curated and integrated biological macromolecular information in the context of function, biological processes, evolution, pathways, and disease states.

XML

XML-Extensible Markup Language

• Defines a set of rules for encoding a documents
• Can be both human-readable and machine-readable
• It a designed to create data
• It is a textual data format with strong support via Unicode
  
  
  
  
  
  
  

            Here's steps on how to write a simple XML file:

             1. Creating a file   

             2. Writing the declaration

             3. Adding a comment

             4. Defining the root element

             5. Adding attributes to an element

             6. Adding a nested  elements

             7. Adding HTML-style text

             8. Adding an empty element

             9. The finished product

WHAT IS NETWORK????

A network is a group of  two or more computer system linked together. Computers on a network are sometimes called nodes. Nodes can include hosts such as personal computers, phones, servers as well as networking hardware. Two such devices are said to be networked together when one device is able to exchange information with the other device. 

Computer networks differ in the physical media used to transmit their signals, the communications protocols to organize network traffic, the network's size, topology and organizational intent. A computer network facilitates interpersonal communications allowing people to communicate efficiently and easily via email, instant messaging, chat rooms, telephone, video telephone calls and video conferencing. 

Important feature of many networks is to provide access to information on shared storage devices. Besides that, a network allows sharing of files, data, and other types of information giving authorized users the ability to access information stored on other computers on the network. Users may access and use resources provided by devices on the network such as printing a document on a shared network printer. A computer network may be used by computer crackers to deploy computer viruses or computer worms on a devices connected to the network or to prevent these devices from accessing the network.

Types of Networks :

NETWORKS	DESCRIPTION
local-area networks (LANs)	The computers are geographically close together (that is, in the same building).
wide-area networks (WANs)	The computers are farther apart and are connected by telephone lines or radio waves.
metropolitan-area networks MANs)	A data network designed for a town or city.
home-area networks (HANs)	A network contained within a user's home that connects a person's digital devices.
campus-area networks (CANs)	he computers are within a limited geographic area, such as a campus or military base.
