Advantages And Disadvantages Of Computer Network

Here’s a snapshot of the most common advantages and disadvantages of computer network:

We will now study each of these advantages and disadvantages in detail in the sections below.

Advantages Of Computer Network

A network is very useful for connection and communication purposes. Not just that, it also has many other advantages. Below are some of the prominent ones:

1. Ease Of Accessibility

Computer networks provide easy accessibility to resources, information, and online services from anywhere. Users can work remotely, access educational resources, and retrieve personal files. Communication and collaboration are seamless through email, instant messaging, and video conferencing. Resources can be shared and distributed, reducing costs and enabling efficient utilization. Modern computer networks are easy to explore. So, even if you are a kid or a person new to technology, you'll find it easy to connect.

2. Flexibility

Here, flexibility means that different people will be able to explore different things as per their requirements. For this purpose, computer networks provide you with a wide array of choices to share a particular piece of information. For example, e-mail or messaging apps like WhatsApp.

3. Convenient Resource Sharing

The main aim of a computer network is to enable sharing of resources among its users. You can use resources such as printers, scanners and photocopy machines that can be shared across multiple users. This resource sharing is important for big companies as they can use one single common network to connect with their employees. 

4. Connectivity

Computer networks improve connectivity irrespective of a person's location. The pandemic brought this advantage to the forefront, with people regularly using video call apps like Zoom or Google Documents to connect with their friends and colleagues. 

5. Security

Computer networks provide security through authorization. Authorization is done via user ID and password. So, it ensures that when we log in, we are only able to do it when there is a perfect match between our details and the details stored in the database. 

6. Great Storage Capacity

Organizations have an abundance of data that needs to be stored. For that purpose, they are required to store them in a central server. A central server is a remote server that is accessible to every employee. So, if in case one loses the data, others have it. 

 7. Reduced Cost

Cost is one of the crucial factors that one needs to consider while evaluating the pros and cons of a particular technology. In networking, a central server is used that enables companies to store files in one place, thus reducing file storage expenses.

8. Enhanced Collaboration

With a computer network, individuals can easily share files, documents, and information with each other, making it easier to work together on projects and tasks. This can lead to increased productivity and efficiency in the workplace. Additionally, computer networks often include communication tools such as email and instant messaging, allowing for real-time communication and collaboration regardless of physical location. Overall, computer networks facilitate seamless collaboration and teamwork.

Disadvantages Of Computer Networks

While computer networks aid our work, they also come with their own set of disadvantages such as:

1. Lack Of Robustness

Computer networks rely on the main server called the central server. If the central server malfunctions or there is an issue in the central server, then the entire network will stop functioning. So, this is a major disadvantage due to dependency on a single server.

2. Spread Of Computer Virus

As computers in a network are interconnected, there is a high probability that if one of the computers is affected by the virus, others too can get affected. This spread can actually damage the entire system. Also, if the central server gets corrupted, then it's quite dangerous as the network depends on the central server.

3. Costly To Set-up And Maintain

While computer networks save costs in terms of resource sharing and data storage, they also incur considerable implementation costs. Moreover, maintaining computer networks is a costly and time-consuming affair.

4. Lack Of Productivity

Since a network has a lot of advantages and applications, it certainly results in the simultaneous use of many services that cause distraction. Thus, due to employees focusing on a myriad of tasks, productivity issues are quite common. 

5. Health Issues

Computer network provides access to a gamut of services including entertainment, gaming, and movies. These result in making you addicted to the content and thus result in overuse of these services. This excessive screen time makes you feel lethargic and causes eye strain and body pain.

6. Lowers The Ability To Retain And Analyze Information

With computer networks storing vast amounts of data and processing basic requests in a fraction of the time, people are losing the ability to retain important information. Even processing basic information is a task, as individuals are becoming increasingly dependent on computer networks to do these tasks for them.

7. Unauthorized Access

When multiple devices are connected to a network, there is a greater potential for unauthorized access and data breaches. Hackers can exploit vulnerabilities in the network infrastructure or gain access to sensitive information through one compromised device. This can lead to the theft of personal or confidential data, financial loss, and damage to the reputation of individuals or organizations. To mitigate this risk, network administrators must implement robust security measures, such as firewalls, encryption, and regular software updates, to protect the network and its connected devices from cyber threats.

Applications Of Computer Network

Now that we’ve studied the key advantages and disadvantages of computer network, let’s take a look at some of the most common applications of a computer network:
