What is a CDN and How Does It Improve Speed?

In today's digital world, every website owner wants his site to load fast and users to have a good experience. If a website is slow, visitors leave it quickly, which affects both traffic and business. The solution to this problem is CDN (Content Delivery Network) . But many people still do not understand what CDN is and how it increases the speed of our website. In this blog, we will learn step by step what CDN is, how it works and why it is important for modern websites. What is CDN? The full form of CDN is Content Delivery Network . It is a distributed network in which servers are spread across the world. These servers store copies of your website's content (such as images, videos, CSS files, JavaScript files, PDFs, etc.). When a user opens your site, the content is delivered to him from the nearest server. This makes the site load faster because the data does not travel from a far-off server. How does a CDN work? The working of a CDN is simple but the concept is powe...

Difference Between SSD and HDD – Which One is Better?

In today's time, whenever you go to buy a new computer or laptop, a question definitely comes up - should you buy SSD or HDD? Both are storage devices in which your data such as files, photos, videos, software and operating system are saved. But there are many differences between the two, which make a difference in performance, price and life. In this blog, we will know in great detail what is the difference between SSD and HDD, what are their advantages and disadvantages, and which one will be better for you.

What are SSD and HDD?

HDD (Hard Disk Drive)
HDD is an old and long-standing storage technology. It has a rotating magnetic disk and a read/write head inside to store data. It works exactly like data was read from a CD or gramophone.

  • HDD is also called mechanical drive because it has moving parts.

  • It was invented in 1956.

SSD (Solid State Drive)
SSD is a new and fast storage technology. It has no moving parts. It saves data in NAND flash memory chips, just like a pen drive or memory card.

  • SSD is called a solid-state drive because it is completely electronic.

  • It was first introduced by IBM in 1991.

Main differences between HDD and SSD

Now we will understand both of them by comparing them in different aspects so that the decision becomes easier for you.

1. Speed
​​HDD: The speed of reading and writing data is slow because the head has to move to the right place.
SSD: Very fast because there are no moving parts and data is accessed instantly.

2. Cost:
HDD: It is cheaper, i.e. you get more storage at a lower price.
SSD: It is expensive, especially SSD with more storage costs a lot more.

3. Storage Capacity
HDD: Easily available in 1TB, 2TB, 4TB or more storage and is affordable.
SSD: Earlier SSD with high storage was very expensive, now up to 1TB is available at a reasonable price, but it is still expensive compared to HDD.

4. Durability
HDD: Since it has moving parts, it can get damaged quickly if it is hit hard or dropped.
SSD: There are no moving parts, hence it is stronger and more durable.

5. Noise & Heat
HDD: Produces little noise and heat when running.
SSD: Remains completely silent and does not heat up much.

6. Weight & Size
HDD: It is heavy and thick.
SSD: It is light and thin, hence it is mostly used in laptops.

7. Power Consumption
HDD: Consumes more power because it has moving parts.
SSD: Consumes less power, which makes the laptop battery last longer.

Advantages and disadvantages of HDD

Benefits

  • More storage at a lower cost

  • Long-tested and trusted technology

  • Good choice for large data backup

Damage

  • Slow Speed

  • May get damaged quickly due to fall or shock

  • excessive noise and heat

Advantages and disadvantages of SSD

Benefits

  • High Speed

  • More durable and stronger

  • Stays absolutely cool and calm

  • laptop battery lasts longer

Damage

  • is costly

  • More storage costs more

For whom is HDD better?

  • Those who need more storage but have a low budget

  • For large data backup

  • In desktops where portability doesn't matter much

Who is SSD better for?

  • Those who need faster performance

  • For heavy applications like gaming, video editing, designing

  • Laptop users who want something lightweight, durable, and long battery life

SSD + HDD Combination – Best Option
Nowadays many people use a combination of both SSD and HDD.

  • The operating system and necessary software are installed in SSD so that the computer runs faster.

  • We keep large files, photos, videos and backups in HDD so that we can get more storage and also save money.

conclusion

If speed and performance are more important to you and budget is not a problem, then SSD is better for you.
If you need more storage and budget is less, then HDD will be right.
If you want balance then a combination of both SSD and HDD will be best.

How to Implement a Robust Data Backup Strategy?

Putting in place a robust data backup plan is essential to safeguarding your company against data loss brought on by hacker attacks, system malfunctions, or human error. Here's how to put together a reliable backup plan: 1. Determine Vital Information Determine which data is most important for business operations first. Give important intellectual property, financial records, and customer records top priority. https://globalclassified.net/0/posts/3-Services/24-IT/2402359-setup-brother-com.html https://globalclassified.net/0/posts/3-Services/24-IT/2402370-setup-brother-com.html 2. Apply the 3-2-1 Guideline Use the 3-2-1 backup strategy: store two copies of your data on various types of storage, maintain one copy off-site or in the cloud, and maintain three copies of your data (two backups and your production data). 3. Put Backup Procedures in Motion Reduce human error and guarantee consistency by automating backups. Based on the criticality of the data, schedule regular backups to h...

What is two-factor authentication?

Image
The Protection of Your Digital Life with Two-Factor Authentication (2FA) Taking proactive measures to protect our online accounts is crucial in today's increasingly digital environment, when our private information is always in danger. A strong security feature that provides an additional degree of protection, two-factor authentication (2FA) makes it much more difficult for unauthorized users to access your accounts.  Two-factor authentication: what is it? Two forms of identification are needed to confirm your identity as part of the 2FA security process. This implies that a second factor is still required to access your account even if someone knows your password. You may have something, know something, or be something as this second aspect.  Typical 2FA Techniques 1. TOTP, or time-based one-time password: How it operates: Every 30 seconds, a unique code is generated via a time-based code generator software on your phone, such as Authy or Google Authenticator.  Benefits ...
