Simple step-by-step guide to change your Wi-Fi password

 how to setup change password wifi

🔹 Step 1: Connect to Your Wi-Fi

Make sure your device (laptop, phone, or PC) is connected to the Wi-Fi network you want to change.

---

🔹 Step 2: Open the Router Settings Page

1. Open your web browser (like Chrome or Edge).

2. In the address bar, type your router’s IP address, usually one of these:

   • 192.168.0.1

   • 192.168.1.1

   • 192.168.100.1

   • 10.0.0.1

   (If unsure, you can find it by checking your network details — see below for help.)

---

🔹 Step 3: Log In to Your Router

• You’ll be asked for a username and password.

• Default login info is often:

  • Username: admin

  • Password: admin or password

• If you changed it before, enter your custom credentials.

(If you don’t know it, look for a sticker on the back or bottom of your router.)

---

🔹 Step 4: Go to Wireless Settings

Once logged in:

• Look for Wireless, Wi-Fi Settings, or Wireless Security.

• Choose your Wi-Fi network name (SSID) if there are two bands (2.4GHz / 5GHz).

---

🔹 Step 5: Change the Password

• Find the field labeled Password, Passphrase, or Pre-Shared Key.

• Enter your new Wi-Fi password.

  • Use at least 8 characters.

  • Mix letters, numbers, and symbols for better security.

---

🔹 Step 6: Save and Reconnect

• Click Save or Apply.

• Your router will restart or disconnect briefly.

• Reconnect your devices using the new password.

---

💡 Optional: Find Your Router’s IP Address

If you’re not sure of your router’s IP:

On Windows:

• Press Windows + R, type cmd, then press Enter.

• Type ipconfig and press Enter.

• Look for Default Gateway — that’s your router’s IP.

On Android/iPhone:

• Go to Wi-Fi settings, tap the connected network → look for Gateway or Router IP.

oracle database work

Oracle database is a collection of physical operating system files or disks (in the simplest terms). Oracle instance is set of Oracle background processes or threads and a shared memory area, which is memory that is shared across those threads or processes running on a single computer. There are basically 9 Processes but in a general system we need to mention the first five background processes.They do the housekeeping activities for the Oracle and are common in any system.

The various background processes in oracle.

1) Database Writer(DBWR) :

Database Writer Writes Modified blocks from Database buffer cache to Data Files.This is required since the data is not written whenever a transaction is committed.
2)LogWriter(LGWR) :

Log Writer writes the redo log entries to disk. Redo Log data is generated in redo log buffer of SGA. As transaction commits and log buffer fills, LGWR writes log entries into a online redo log file.
3) System Monitor(SMON) :

The System Monitor performs instance recovery at instance startup. This is useful for recovery from system failure
4)Process Monitor(PMON) :

The Process Monitor performs process recovery when user Process fails. Pmon Clears and Frees resources that process was using.
5) CheckPoint(CKPT) :

At Specified times, all modified database buffers in SGA are written to data files by DBWR at Checkpoints and Updating all data files and control files of database to indicate the most recent checkpoint
6)Archives(ARCH) :

The Archiver copies online redo log files to archival storage when they are busy.
7) Recoverer(RECO) :

The Recoverer is used to resolve the distributed transaction in network
8) Dispatcher (Dnnn) :

The Dispatcher is useful in Multi Threaded Architecture
9) Lckn :

We can have up to 10 lock processes for inter instance locking in parallel sql

How dangerous is the coronavirus 2020

The coronavirus is extremely dangerous, and I suspect that the danger is currently being underplayed by the world medical community to minimize panic as we prepare for the worst.
Covid-19 is deadly, although fatality rates skyrocket for the elderly and those with compromised immune systems.

First and foremost, it is really important to know that as of today (February 17, 2020), there is still much we do not know about SARS-CoV-2 (i.e. the official name of the novel coronavirus) and COVID-19 (i.e. the official name of the disease caused by SARS-CoV-2). This uncertainty makes this question difficult to answer with a short or simple response.

However, epidemiologists and scientists from around the world are making rapid and significant real-time progress in understanding the nature of this novel coronavirus. Earlier today, a comprehensive report from the China CDC was released on over 70,000 individual cases in China, which included data for 99% of confirmed cases globally as of February 11th, 2020.

As I stated at the very beginning, there are still many unknowns out there. That is why there is no simple answer to the question of how dangerous this thing really is. Among others:

• There is no vaccine against COVID-19 (one that can be deployed safely at scale)
• We are still unsure about how contagious this is in people that are infected but asymptomatic
• We do not know how many people are infected, because (very likely) many people are infected and not yet identified for a variety of reasons
• We do not know exactly why infection and/or mortality rates for young people are so much lower
• We do not know how countries with less-developed healthcare systems will be able to cope with potential outbreaks
• SARS-CoV-2 will continue to mutate and evolve (although scientists aren’t that worried about this)
• It’s hard to predict the second-order effects (e.g. policy under/over-reaction, economic disruption, etc.)

What is the difference between DBMS and SQL

DBMS is a system and SQL is a language

DBMS (Database Management System)
A DBMS is a software for creating and managing databases. The DBMS provides users with a systematic way to create, retrieve, update and manage data. It is a middleware between the database which store all the data and the users or applications which need to interact with that stored database. A DBMS can limit what data the end user sees, as well as how that end user can view the data, providing many views of a single database schema

SQL (Structured Query Language)
SQL is the programming language which is used to access this DBMS and the database. It is the language in which you write the command regarding how and what to access in the database. In the figure above, API is what is SQL. The APP or the USER writes SQL commands which are processed by the DBMS

We use the DBMS system along with SQL for querying data in the database.

Now, for knowing the difference, you must understand one thing that is - in SQL we can see the data we want by asking a query, while DBMS optimizes the query and show us the data.

Let’s understand it with the example -

Suppose, you have a table that contains details of different persons such as name, age, gender, mobile number, address etc.

Now, if you want to see the mobile number of a person, you simply gave a query to DBMS, DBMS here starts working, catches query and finally, it will show you the mobile number of that person.

A DBMS (database management system) is a software system that allows you to store and retrieve data in an efficient and organized manner.

SQL is a formal language that allows you to communicate with many DBMS to insert, query, update, delete the content.

A large subset of the DBMS uses SQL, most notably almost all so-called "relational" DBMS. However, there are non-relational DBMS that use SQL (e.g. IDMS), and relational DBMS that don't use SQL (in particular the early versions of Ingres and Postgres)

Spiderman : Homeless Recent Buzz about the Exit of Spiderman Franchise from MCU

In a Sony statement to USA TODAY Tuesday night, the studio said the outstanding issue remained over the future involvement of Marvel President, and comic movie mastermind, Kevin Feige as producer in future Spider-man films.

 

 

So when the two companies agreed to share his rights in 2015, it felt like a homecoming -- Spider-Man was finally able to appear in films in the Marvel Universe.

Now played by Tom Holland, the character has appeared in five Marvel movies since that deal -- most recently this year's "Spider-Man: Far From Home."

 If Sony and Disney can't come to a deal, Spidey might not be in Marvel movies in the near future – but he probably wouldn't be anyway, unless for some reason he was supposed to be in "Black Widow" or "The Eternals," the MCU's next two films (which is highly doubtful). There's plenty of time to work stuff out.

Pulo Cinta Resort is an Indonesian Maldives

Pulo Cinta has a very unique historical story. Once upon a time during the Dutch colonial era, this island became a place of escape between the Prince of Gorontalo and the daughter of one of the Dutch traders.
