1. Bluetooth is a wireless technology standard used for exchanging data between fixed and mobile devices over short distances using short-wavelength UHF radio waves in the industrial, scientific and medical radio bands, from 2.402 GHz to 2.480 GHz, and building personal area networks (PANs).
2. A server is a computer that provides data to other computers. It may serve data to systems on a local area network (LAN) or a wide area network (WAN) over the Internet.
3. node is a basic unit of a data structure, such as a linked list or tree data structure. Nodes contain data and also may link to other nodes. Links between nodes are often implemented by pointers.
4. A network is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another to allow the sharing of data. An example of a network is the Internet, which connects millions of people all over the world.
5. Answer
It enhances communication and availability of information. ...
It allows for more convenient resource sharing. ...
It makes file sharing easier. ...
It is highly flexible. ...
It is an inexpensive system. ...
It increases cost efficiency. ...
It boosts storage capacity.
6. Network security is a broad term that covers a multitude of technologies, devices and processes. In its simplest term, it is a set of rules and configurations designed to protect the integrity, confidentiality and accessibility of computer networks and data using both software and hardware technologies.
7. A client-server network is the medium through which clients access resources and services from a central computer, via either a local area network (LAN) or a wide-area network (WAN), such as the Internet. ... A major advantage of the client-server network is the central management of applications and data.
8. A flat-file database is a database stored in a file called a flat file. Records follow a uniform format, and there are no structures for indexing or recognizing relationships between records. The file is simple. A flat file can be a plain text file, or a binary file
9. Its components include: ActiveX Data Objects (ADO), OLE DB, and Open Database Connectivity (ODBC). There have been several deprecated components as well, such as the Microsoft Jet Database Engine, MSDASQL (the OLE DB provider for ODBC), and Remote Data Services (RDS).
10. A database is an organized collection of structured information, or data, typically stored electronically in a computer system. A database is usually controlled by a database management system (DBMS). ... Most databases use structured query language (SQL) for writing and querying

1.b A LAN, abbreviated from Local Area Network, is a network that covers a small geographical area such as homes, offices and groups of buildings. Whereas a WAN, abbreviated from Wide Area Network, is a network that covers larger geographical areas which can span the globe
2.b.Improved data sharing
An advantage of the database management approach is, the DBMS helps to create an environment in which end users have better access to more and better-managed data.
Such access makes it possible for end users to respond quickly to changes in their environment.
2. Improved data security
The more users access the data, the greater the risks of data security breaches. Corporations invest considerable amounts of time, effort, and money to ensure that corporate data are used properly. A DBMS provides a framework for better enforcement of data privacy and security policies.
3. Better data integration
Wider access to well-managed data promotes an integrated view of the organization’s operations and a clearer view of the big picture. It becomes much easier to see how actions in one segment of the company affect other segments.
4. Minimized data inconsistency
Data inconsistency exists when different versions of the same data appear in different places. For example, data inconsistency exists when a company’s sales department stores a sales representative’s name as “Bill Brown” and the company’s personnel department stores that same person’s name as “William G. Brown,” or when the company’s regional sales office shows the price of a product as $45.95 and its national sales office shows the same product’s price as $43.95. The probability of data inconsistency is greatly reduced in a properly designed database.
