HDD vs SSD

-

Before going to know the differences between HDD and SSD, firstly know about the working principle to understand clearly:

HDD:

Internal structure of HDD

 Hard Disk Drives access or data with the help of moving parts inside it. HDD stores the data in the form of tracks and sectors.

Tracks and sectors
Accessing and writing data depends on the rotating speed of the disk inside it.

SSD: 
The solid-state drive works with the help of flash memory. It consists of a microcontroller and cache memory inside it.

Internal structure of SSD

Differences between HDD and SSD:

1.SSD is faster than HDD because HDD contains moving parts which has limitations whereas SSD has no moving parts and contains a microcontroller, cache memory which helps us to work fastly.

2.SSD requires less power consumption than HDD because SSD has no moving parts.

3.HDDs are more prone to damage than SSDs.

4.SSD is costlier than HDD.

5.Data durability(storing data for more time) is more in HDD than SSD.

We can observe SSD has more benefits than HDD. If you are buying a laptop choose a laptop with SSD for good performance.

If you want to store much data at a reasonable cost, go for HDD.
If you want fast and best performance irrespective of cost, go for SSD.

    Hi,
    You shared a very good post about Samsung SSD hard drives. SSDs generally use NAND-based flash memory which retains memory even without power. SSDs using volatile RAM also exist for faster access. The hybrid drive combines the features of an HDD and an SSD in one unit, containing a large HDD, with a smaller SSD cache to improve the performance of frequently accessed files. Recently I purchased Samsung ST3200FM0023 SSD for my Laptop from ESAI TECH at an affordable price.

why lays or kurkure is filled with air?

 Why air is filled in packets?  What is that air present in that packets?  Is it safe to take it?   The air inside this packet is Nitrogen. This air helps not to spoil. This increases the expiry date. You may get doubt. The reason is when you expose your food to normal air it leads to spoiling after few days. Nitrogen helps to increase life span. It is also a marketing strategy to show that the quantity is more. When we open it only half is filled in that packets. Nitrogen is a natural gas and it won't harm our health. It is a preservative gas. In 1994, scientists found that exposing chips to nitrogen not only helped to extend the shelf life but also made them taste better. " It may disappoint you that the packets are filled with air rather than products but remember it is to increase expiry date🤷‍♀️🤷‍♀️"

   What is the new policy introduced by WhatsApp?  was it introduced to steal our data?  Is WhatsApp is trying to expose our data?  what is the alternative to WhatsApp? These are the questions revolving around everyone from past some days. Firstly we have to know what is the policy introduced by WhatsApp? Have a look: The data in WhatsApp are shared by third parties. This has to be agreed upon by Feb 8. According to this policy, they will use our data like phone number, IP, mobile information, and logs to provide ads only. They will not steal our data. The messages will be secure. There will be private for your messages. No need to panic about this. There is no harm to us by that policy. The only change is we will see some ads that are it. Again I am repeating that they are not stealing all information from us. They mentioned which information is taken from us. Our messages will be end-to-end encrypted. Whatsapp has named secured app till now from further also it will be secure. Our me

Firewall -- security guard for our computers

We have to be very careful with the internet. Don't trust the internet, it may cause damage to you. With the increasing usage of computers, hackers are becoming more active to steal our data.  Say thanks to the firewall as it is protecting us from hackers or malicious data. Let us know the meaning of a firewall? A firewall is an important component in a network that filters the incoming and outgoing traffic based on the requests from the user or organization. It acts as a barrier between private networks and the public internet. Let us see the difference with and without a firewall If the firewall is not available while we are accessing data from the internet, hackers can easily enter into our computers and can steal data. But if the firewall is present it can filter the data and can send the data which is needed for us. It blocks the entry of hackers into our system with the help of IP addresses. What are the types of firewalls? Host-based firewall: It is a type of firewall which
