Causes of data loss

Causes of data loss

You may be able to get back some of your data when you delete by mistake. However not all your data can be recovered and even if you recover the process can be complicated. You need to know the causes of data loss and do your level best to avoid them. Below are some of the major causes of data loss.

Hard drive damages

Hard drives are the most fragile computer parts. They tend to break down often than all the devices used in computing. The hard drives have many moving parts which make them break down easily. Recovering data from damaged or faulty hard drives is very complicated and can be very costly. Hard drives can die a natural death due to manufacturing defects, or they can die from mechanical damage. Regular backups are helpful in case the hard drive fails.datalossleftsdfjgkhb

 

Viruses

Different types of viruses are known to attack computers each day. Being connected to the internet has many advantages but it exposes your computer to a lot of serious risks. Most of these viruses affect operational software damage stored data and misuse your internet connection. Viruses are normally aimed at stealing and damaging business data.

 

Power failures

Power failures have two adverse effects. When writing a document without saving it, then if there is a power failure when you are midway you will lose the data. This is even worse when you are dealing with a sophisticated database. Another problem arises when a power failure interferes with the hardware and operations systems of the computer. Shutting down your computer without following the shutdown procedures can cause problems with rebooting the operating system. Such problems may cause a chain reaction and make your data inaccessible.

Theft of computer

Losing your computer and data is a real tragedy. There is a danger of your computer being stolen at home or while traveling. You may leave your laptop at the airport, coffee shop or conference center unattended and lose it in that manner. Losing your computer can be less painful if you have a proper backup and if you store your data in safe storage.

Deleting files by mistake

datalossrightzsgdxhfcgjvbThe major risk of data loss is deleting them without having backups. Deleting and updating files are common activities that we do every day. This is why most people tend to overwrite data that they do not intend to. Most people today treat data loss at work as natural that they do not consider it a real risk. Having backup strategies and proper workflow procedures can help prevent data loss.

These are some of the causes of data which you should avoid for your data to be safe.…

What to know about printed circuit boards

What to know about printed circuit boards

Printed circuit boards are made by adding layers of copper to the board so that the components and wires are connected. They are featured in all electronic devices and are affordable to produce. PC boards are used in cell phones computers and military equipment. Below are some of the pros and cons associated with PC boards.

Pros

Short-circuit is minimal

PC boards use embedded copper tracks which are effective at preventing wrong wiring and short- circuit issues. It is also easy for manufacturers to test the boards using computers before they print them. Testing the boards when manufacturing them ensures there is little chance of errors when using them.pcbleftsgdhfjgk

Inspection is not necessary

These boards are designed specifically and printed using computers there is no need for further inspection. Besides, the possibility of broken circuits is significantly lower than boards that are prepared manually.

Easy maintenance

Maintenance of PC boards is much easier since the components are fixed, and there are no loose parts or complex wiring on the printed circuit board. Every component is fixed in place making it easy to identify the various parts. The fact that the design is simple, providing maintenance is straightforward.

Low-cost production

PC boards are the best option if you want mass production of a single design. After printing the first design and etching it onto the copper board, it becomes affordable and fast to reproduce multiple boards within a short time frame.

Cons

Single use

Printed circuit boards are meant for only a single use. If you intend to use various types of circuits, you may need to design a new board. Other types of boards such as breadboards offer greater flexibility for use as opposed to PC boards.

Etching process is harmful to the environment

The process of etching the boards onto a copper board to produce the PC board depends on some chemicals which harm the environment. This means the process is not environment-friendly.

Updating is impossible

pcbrightszgxdhfcjvgbnOnce you have printed the board using a computer, you cannot go back and make changes. If some parts or components are required, you will have to reprint the whole design. This will inconvenience you wanted to test only one component of the board.

PC boards are used in all electronic products because of the outlined advantages. The disadvantages can be managed, but it is good to know what you are going to encounter before using these boards.
