What is a data recovery system?


Database Systems, like any other computer system, are subject to failures, but the data stored in them must be available as and when required. When a database fails, it must possess the facilities for fast recovery. It must also have atomicity, i.e. either transactions are completed successfully and committed. The transaction should not affect the database. The network installation Hobart is helpful for the success of business. 

What is a Data Recovery System?

The data recovery system is also known as the Database recovery technique. Data recovery is the process of restoring data that has red. The main goal of recovery techniques is to ensure data integrity and consistency and prevent data loss. Mainly there are two types of recovery techniques. One is the Rollback/Undo Recovery Technique, and another is the Commit/Redo Recovery Technique. 

Types of the database recovery technique

  • Rollback recovery technique: This type of technique is also known as undo recovery technique. The undo recovery technique is based on the principle of backing out or undoing the effects of a transaction that has not been completed successfully due to a system failure or error. This technique is accomplished by undoing the changes made by the transaction using the log records stored in the transaction log.
  • Commit recovery technique: The other name for the Commit recovery technique is the redo recovery technique. The redo recovery technique is based on the principle of reapplying the changes made by a transaction that has been completed successfully to the database. This technique is accomplished by using the log records stored in the transaction log to redo the changes made by the transaction that was in progress at the time of the failure or error.

What are the benefits of the data recovery technique?

Data recovery provides you with several benefits.

  • Data security: One of the most crucial parts of data backup and recovery is security. The importance of data backup and restore solutions with solid security are critical to protecting an organization.
  • Data recovery and replication: The goal of the data backup is to ensure data recovery and restoration. A sound recovery system can help you to avoid downtime and keep your business running smoothly. 
  • Easy Data Management: Data recovery is a time-consuming and unpleasant operation. As a result, organizations often have various complications in data management during restoration. However, using the correct data backup program makes managing the recovery process effortless. A reliable data backup system helps users back up their data frequently and consistently. 
  • Cost Control: losing vital organization data can put your company out of the business. Losing customers’ sensitive information can lead to lawsuits; data loss can stall projects, cause productivity decrease, and financial losses.
  • Unhindered performance: Manually backing up an organization’s data is time-consuming and resource-intensive. Company servers often have difficulties handling a large amount of data. Backup and recovery programs can offer you the perfect solutions in likely situations. 

Nowadays, almost every company uses the database recovery technique because of its benefits. ITechnology Australia is known as the best Network Installation Company Moonah.

What is 5G: Its Origin, Working, Advantages and Disadvantages

5g is an updated version of 4g, like 4g stands for 4th generation similarly 5g stands for 5th generation. 5g is the fastest network in the world and it provides wireless technology which means to deliver the fastest data speed in multi-Gbps. If you also want to install this network in your home, office or institute, then you can visit the best consultant for network installations in Moonah. In this blog, we will provide important information about the 5g network, how it works and its origin.

The Origin Of 5g Network

The worlds fastest network 5g was launched for the first time in South korea in April. Swedish telecom giant Ericsson predicts that the 5g network will cover 65% of the world’s population by the end of 2025. Till now 40% of the world’s population has been covered by the 5g network. Day by day the number of users on the 5g network are increasing.

How 5g Network Works


5g or the 5th generation utilizes higher frequency radio waves; this wireless technology has been working only with the help of these frequency radio waves. The 5g network uses advanced technologies to provide more reliable communication, and fast speed as compared to 1g, 2g, 3g, and 4g networks. The 5g network operates higher bands as compared to the rest of the four networks i.e, 1g, 2g, 3g, 4g. 

The radio waves are presented in millimeter or millimeter waves (mmWaves). The range of these waves are 24 GHz and above, similar to sub-6 GHz frequencies. Higher frequency allows higher speed of the network.

Advantages Of 5g Network

 The following are the advantages of 5g network:

  1. Faster Speeds: 5g improves overall network speed, it helps in smoother downloads, enjoy watching movies, videos, online classes, online meetings without buffering. 5g provides the highest mbps speed between 40 mbps to 60 mbps. 5g offers faster data speed as compared to its previous generation. 
  2. Low latency: The main purpose of 5g is to consume ultra-low latency. 5g reduces the time it takes for data to travel between devices. If you want to experience 5g, then you can search for the best data cabling in Rose Bay. 
  3. Enhanced Connectivity: 5g is more reliable and provides reliable and stable connectivity all over the world. It works better even in highly populated areas or places with high usage of the network.

Disadvantages Of 5g Network:

Following are the disadvantages of 5g network:

  1. Expensive Infrastructure: Implementing a 5g network is expensive and a kind of infrastructure investment. However, there are various network companies that offer 5g network installation in Moonah at an affordable cost.
  2. Device Compatibility: Device compatibility is a disadvantage for the users who use old devices, because 5g may not work in them. 5g works only in the new version and smart phones or devices which support the 5g network.


The 5g network is the fastest network in the world. People have started installing this fastest network to experience the high speed data and to enhance their connectivity. If you also want to enjoy the 5g network, please consult with your nearest network installation in Moonah, and start taking benefits of 5g technology.
