Preserving Information

Preserving metadata is a key component of digital shielding, and includes information that documents the preservation process. Supports group management practices and allows organizations or individuals to understand the nursery chain.

The information can be backed up in a central location or several backup servers. Allows all computers in the network to access the information at a later time. This information can be stored for many years and can be provided when needed.

Protecting Information

Protecting Information

A network provides a secure environment for important data of an organization. They provide an additional layer of protection through user accounts, logins, and passwords. Different levels of access to the network can be set. The main goal is to ensure that information is properly protected from modification or disclosure. It should define the sensitivity level of information.

Powerful Communication Medium

 A communication medium is simply how your message is sent to the receiver. It is often known as the communication channel.

Powerful communication medium

Using the network is easy for many people to communicate effectively. It enhances human-to-human communication because, in remote geographical areas, people can easily share and share information, ideas, and technology.

Expandability

Expandability

Expanding a computer system to adjust its capabilities or additions to capabilities From a hardware perspective, expandability may include extra or large hard disks and more storage. Network size and performance can be gradually increased by adding more processor and communication devices.

Saving Money

It is economical to set up a network of small computers in large numbers compared to investing in some big people. Data on the network can be placed on one or more shared, powerful file server machines.

Saving Money

One network makes it easy for everyone to access the same file, and people inadvertently stop creating different versions. The network also allows many employees to share the same printer. Although you may need a more expensive printer to handle additional workloads, it is still economical to use a network printer, which connects to a different printer for each computer in your office.

Distribution of Workload

Distribution of workload

Workload contains some amount of application programming in the computer and usually, some users are connected to and interacting with computer applications.

A large and complex task can be distributed among several processors in the network. Or if a computer becomes saturated with too much load, the work can be distributed to other computers on the network.

Provide High Reliability

Provide High Reliability

In computer networking, a trusted protocol is a protocol that indicates to the sender whether the delivery of data was successful to the intended recipient.



High reliability ensures that network devices, data, and links are available at all times. It can be obtained from the alternative source of supply. For example, having a backup server, replication of files on more than one machine ensures the availability of data and files from at least one source. Having multiple CPUs means that if someone fails, the other can handle their work. It is very important in military, banking, air traffic control, and similar applications.

Network Goals

Network Goals

The Network Goals are:

1. Resource Sharing
2. Provide High Reliability
3. Distribution of Workload
4. Saving Money
5. Expandability
6. Powerful Communication Medium
7. Protecting Information
8. Preserving Information

Resource Sharing

It is a piece of information on a computer that can be remotely accessed from another computer, usually through an enterprise Internet, transparently as it was a resource in the local machine. Network sharing is possible through interoperability communication over the network.

Resource Sharing

The goal of sharing resources is to provide all programs, data and equipment to anyone on the network regardless of the resource and user's physical location. The offices of the modern organization are located in different parts of the country and the world. To share information about the entire organization, it is necessary to add a computer to all these places.
