Features of a computer network

A list Of Computer network features is given below.

• Communication speed
• File sharing
• Back up and Roll back is easy
• Software and Hardware sharing
• Security
• Scalability
• Reliability

Communication speed
Network provides us to communicate over the network in a fast and efficient manner. For example, we can do video conferencing, email messaging, etc., over the internet. Therefore, the computer network is a great way to share our knowledge and ideas.

File sharing
File sharing is one of the major advantages of the computer network. A computer network allows us to share files with each other.

Back up and Roll back is easy
Since the files are stored in the main server, which is centrally located. Therefore, it is easy to take the backup from the main server.

Software and Hardware sharing
We can install the applications on the main server; therefore, the user can access the applications centrally. So, we do not need to install the software on every machine. Similarly, hardware can also be shared.

Security
Network allows security by ensuring that the user has the right to access the certain files and applications.

Scalability

Scalability means that we can add the new components on the network. Network must be scalable so that we can extend the network by adding new devices. But, it decreases the speed of the connection and data of the transmission speed also decreases, this increases the chances of error occurring. This problem can be overcome by using the routing or switching devices.

Reliability
A computer network can use an alternative source for data communication in case of any hardware failure.

Advantages of a computer network

Every technology and system provides merits and demerits. Similarly, a computer network also possesses several advantages and a few disadvantages. Some of them are discussed below.

1.Resource sharing

Resource sharing is the main advantage of the computer network. The goal is to provide all the programs, data and hardware to everyone on the network without regard to the physical location of the resource and the users.

2. Inexpensive system

Installing networking software on the device would not cost too much, as it is assured that it lasts and can effectively share information to the peers. Also, there is no need to change the software regularly, as mostly it is mostly not required to do so.

3. Powerful communication medium
A computer network helps people who live or work apart to report together. So, when one user prepared some documentation, he can make the document online, enabling other to read and convey their opinions.

4. Increases system security

Only authorized user can access resource in a computer network. Users are authenticated by their user name and password. Hence it is not possible to access the data unauthorized persons.

5. Storage Capacity
A computer network is used to share information, files, and resources with other people and ensures that all data and content are properly stored in the system. With the help of computer technology, we can do all of this without any problem, while having all the space we need for storage.

Disadvantages of Computer Networking

1.It lacks independence
Computer networking involves a process that is operated using computers, so people will be relying more on computer work, instead of exerting effort for their tasks at hand. Aside from this, they will be dependent on the main file server, which means that, if it breaks down, the system would become useless, making users idle.

2.It poses security difficulties
Because there would be a huge number of people who would be using a computer network to get and share some of their files and resources, a certain user’s security would be always at risk. There might even be illegal activities that would occur, which you need to be careful about and aware of.

3.It lacks robustness.
As previously stated, if a computer network’s main server breaks down, the entire system would become useless. Also, if it has a bridging device or a central linking server that fails, the entire network would also come to a standstill. To deal with these problems, huge networks should have a powerful computer to serve as a file server to make setting up and maintaining the network easier.

4. It allows for more presence of computer viruses and malware

There would be instances where stored files are corrupt due to computer viruses. Thus, network administrators should conduct regular check-ups on the system, and the stored files at the same time.

5.It requires an efficient handler:
For a computer network to work efficiently and optimally, it requires high technical skills and knowledge of its operations and administration. A person just having basic skills cannot do this job. Similarly, network configuration and connection is very tedious and cannot be done by an average technician who does not have advanced knowledge.

6. It requires an expensive set-up Though computer networks are said to be an inexpensive system when they are already running, their initial setup cost can still be high, depending on the number of computers to be connected. Expensive devices, such as routers, switches, hubs, etc., can add up to the cost. Aside from these, it would also need network interface cards (NICs) for workstations in case they are not built in.

Application of computer networks

1. Communication
   Computer networks are widely used for communication. People can send emails, messages, and make voice or video calls using the internet. This helps students, teachers, and offices communicate quickly and easily.

2. Resource Sharing
   In a computer network, hardware and software resources can be shared. Devices like printers, scanners, and storage can be used by many computers at the same time. This saves cost and time.

3. Data Sharing and File Transfer
   Computer networks allow users to share files, documents, images, and videos easily. Students can submit assignments online, and teachers can share study materials through networks.

4. Education and E-Learning
   Computer networks support online education. Students can attend online classes, watch video lectures, and access digital libraries. This makes learning possible from anywhere.

5. Business and E-Commerce
   Businesses use computer networks for online transactions, marketing, and customer support. E-commerce websites allow people to buy and sell products online safely.

6. Entertainment
   Computer networks are used for entertainment purposes such as online games, music streaming, and watching movies. Users can enjoy digital content anytime through the internet.

7. Banking and Online Services
   Banks use computer networks to provide online banking, ATM services, and money transfer. People can check balances, pay bills, and transfer money easily.
