COmputer Network Goals:-

Simultaneous Access

Commonly used data and resources can be kept on a central location, called Network Server, from where users can simultaneously access.

If data is stored centrally, it is called a file server

Programs also can be centrally located in the server, which can be accessed by users on the network- Client server model

Applications also can be centrally located on server ( Application Server)or in clients in distributed mode of processing.

Shared Peripheral devices-

"A type of network in which each workstation has equivalent capabilities and responsibilities. This differs from client/server architectures, in which some computers are dedicated to serving the others."

“Programmer writes their code in a manner which is friendly for other programmers to modify and redistribute and use publicly”.  

Advantages & disadvantages of DDA:-

• Faster than the direct use of the line equation and it does not do any floating point multiplication.
• Floating point Addition is still needed.
• Precision loss because of rounding off.
• Pixels drift farther apart if line is relatively larger.

Some of the elements of OOP are:-

Inheritance:-
Inheritance is the process of deriving new classes from an existing base class.Here the derived classes not only inherits the capabilities of the base class but add refinement of its own.

Amplitude modulation (AM) is a technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. AM works by varying the strength of the transmitted signal in relation to the information being sent. For example, changes in the signal strength can be used to reflect the sounds to be reproduced by a speaker, or to specify the light intensity of television pixels.

DBMS offers several advantages over file processing. The principal advantages of a DBMS are the followings:

   1. Controlling Redundancy
   2. Restricting Unauthorized Access
   3. Providing Persistent Storage for Program Objects and Data Structures
   4. Multiple User Interfaces

The advantages of flowcharts are as follow:-

A technique for organizing and coding computer programs in which a hierarchy of modules is used, each having a single entry and a single exit point, and in which control is passed downward through the structure without unconditional branches to higher levels of the structure. Three types of control flow are used: sequential, test, and iteration.

A structured program is one consisting entirely of three types of logic structures:
