1. Computer won’t start.

If your computer has difficulty starting up or is not powering on, the first thing you should check is the power supply. If you are using a laptop computer and if it’s not turning on with your battery pack in, that could only mean you have a faulty battery pack. Try to remove the battery from your laptop and plug it directly to the power outlet. If you are using a desktop computer and it is not booting up, try to check the power supply by plugging in another device. You can also try plugging it to another outlet to determine if it’s a power outlet issue or computer issue.

2. WiFi keeps on disconnecting

This issue can be a tricky one because you have to try different things to know exactly where the issue is coming from. First, check different devices to know if it is a device issue or not. Second, check your router/modem – make sure that you are showing a green light. Third, call your ISP to know if there’s any line issue in your area.

3. Slow internet

Having a slow internet connection can be caused by many factors. The first thing to do is to clean your computer cache, browsing history, and cookies. Delete unused files and apps from your computer. You may also run your antivirus scanner to make sure that your computer is not infected by a virus.

4. Overheating issue

This is one computer problem that can be easily solved. Make sure that your computer has sufficient cooling system. Make sure that there is proper air ventilation – there should be no blockage such as dust or small debris. Do not place your computer in a warm area or where it can be hit by direct sunlight.

5. Windows won’t boot

When you experience this Windows that won’t boot, the only thing you have to do is to uninstall and reinstall it with the Windows recovery disk.

The use and potential misuse of large volumes of data are a matter of concern for the end users and the vendors alike. Let’s take a look at the challenges and the best possible solutions to the same:

• Adopting right approaches: A part of a robust business continuity plan is to have a backup plan in place if the data gets corrupted or accidentally deleted. Avoiding data corruption or restoring the correct data is possible only through the adoption of proper methods in memory elements and arrays. Latches and flip-flops make an ideal choice for preserving the correctness of the data stored in memory elements. ECCs accommodates simple single error correcting (SEC) or double error detecting (DED) codes to correct more than a single error. These codes are important for scaled-down technologies and high-density memory arrays.
• However, adoption of these powerful ECCs brings along high area overhead and a significant impact on performance. This is mainly due to the storage of a greater number of check bits and more complex encoding and decoding structures.
• Memory Interleaving: There are advanced ECCs to cope up with multiple upsets. One of the most common approaches to deal with multiple errors is to use interleaving in the physical arrangement of memory cells. This helps in segregating the cells that belong to the same logical word. This can be adopted together with SEC/DED codes to protect memory arrays against MBUs. Interleaving cannot be used for register files or small memories because its use may have an impact on floor planning access time and power consumption. Though interleaving generally requires complex and expensive decoding circuitry, it cannot guarantee error correction when the same memory word is affected by two errors.

Let’s take a look at the write-ups that provide a comprehensive reference for the theoretical and practical aspects of innovative approaches for reliable data storage.

• Accurate Model for Application Failure Due to Transient Faults in Caches: This research conducted by Mehrtash Manoochehri and Michel Duboise proposes a solution for the evaluation of cache reliability, in the presence of multi-bit faults, expressed in terms of the failure in time (FIT) metric. In this research paper, authors introduce the concept PARMA+ model which enables FIT rate estimates under all possible sequences.
• High Performance Robust Latches: This research paper, co-authored by Martin Omana and Daniele Rossi, recommends a high-performance robust latch called HiPeR latch. This is insensitive to TFs affecting its internal and output nods regardless of the energy of the radiation particle. The research article also discusses the modified version of the latch and its benefits.
• Concerting: Squeezing in Cache Content to Operate at Near Threshold Voltage: In this research article, Alexandra Ferreron and her colleagues have proposed that large SRAM structures, such as the last-level cache (LLC), enable operation at low voltages with conventional SRAM cells.

In conclusion, it can be summarized that electronic objects can certainly exchange a huge amount of data as the data-exchange is enabled by the IoT.  However, storing it in a reliable way will be challenging. Emphasizing the major challenges in reliable data storage and stimulating further research in the field are the needs of the hour.
