Goals of computer networks

Computer network means in the relation of autonomous (standalone) computer for information 
exchange. The Connecting media could be a copper wire, optical fiber or satellite.

Networking element - The following computer networking included are the following networking element given below:

• At least two computers
• The transmission medium is either wired or wireless
• Protocols or rules that control communication
• Network software such as network operating system.

Computer Network criteria:

The criteria that have to be met by a computer network are as follows:

1. Performance - It is measured in terms of transit time and reaction time.

• Transit time is a time to travel from one message to another
• Response time is an end time between an inquiry and response.

Performance depends on the following factors:

• Number of users
• Type of transmission medium
• Connected network capacity
• Software capacity

2. Reliability - Measured in the context of

• Frequency of failure
• Recovery from failures
• Strength during disaster

3. Security – It means to secure data from permitted access.

Goals of Computer Networks:

The Computer courses in Chandigarh provides some important goals of computer networks:

Resource Sharing –

Many management have significant number of computers in operation, while different ones are located. 
Example. A group of office workers can share the resource through common printer, fax, modem, 
scanner etc.

High Reliability –

If there are alternate sources of supply, then all files can be duplicated on two or machines. If One of them
due to hardware failure and not in available at time, you can use other copies.

Inter-process Communication –

Network users, based geographically apart, may be opposite in a collective session through the user 
network. In order to permit this,, the network must provide nearly error free communication.

Flexible access –

Through any computer you can access the files from any computer network. The project can be 
started on one computer and can be terminated on another computer.

Other goals include distribution of processing tasks, centralized management and allocation of network 
resources, unequal equipment and compatibility of software, good network performance, saving money,
scalability, saving money, access to remote information, communication with the person etc.
