A blockchain is a digital record of transactions. The name comes from its structure, in which individual records, called blocks, are linked together in single list, called a chain. Blockchains are used for recording transactions made with cryptocurrencies, such as Bitcoin, and have many other applications.Each transaction added to a blockchain is validated by multiple computers on the Internet. These systems, which are configured to monitor specific types of blockchain transactions, form a peer-to-peer network.They work together to ensure each transaction is valid before it is added to the blockchain. This decentralized network of computers ensures a single system cannot add invalid blocks to the chain. When a new block is added to a blockchain, it is linked to the previous block using a cryptographic hash generated from the contents of the previous block. This ensures the chain is never broken and that each block is permanently recorded.It is also intentionally difficult to alter past…

Address Resolution Protocol (arp)

ARP Stands for "Address Resolution Protocol." ARP is a protocol used for mapping an IP address to a computer connected to a local network LAN.

Since each computer has a unique physical address called a MAC address, the ARP converts the IP address to the MAC address.

This ensures each computer has a unique network identification.

The Address Resolution Protocol is used when information sent to a network arrives at the gateway, which serves as the entrance point to the network.

The gateway uses the ARP to locate the MAC address of the computer based on the IP address the data is being sent to.

The ARP typically looks up this information in a table called the "ARP cache." If the address is found, the information is relayed to the gateway, which will send the incoming data to the appropriate machine. It may also convert the data to the correct network format if necessary.

If the address is not found, the ARP broadcasts a "request packet" to other machines on the …

India is setting up an IMEI database to Help Track Lost Phones

India's Department of Telecom (DoT) will soon implement a central register of IMEI numbers to tackle the phone theft menace. The DoT will blacklist IMEI numbers that are reported to it as being stolen or lost, blocking access to cellular networks.

Another objective of the central register will be to make IMEI-based lawful interception easier.

India's Telecom Ministry will soon introduce a Central Equipment Identity Register (CEIR), which will have a database of International Mobile Equipment Identity (IMEI) numbers.

IMEI is basically a unique 15-digit number that makes it possible to identify each mobile phone.

The main objective of CEIR will be to bring down the number of mobile theft cases in the country by a significant margin.

Once the Central Equipment Identity Register (CEIR) is implemented, it will allow consumers in India to inform the Department of Telecom (DoT) that their mobile phone has been lost or stolen with the help of a dedicated helpline number.

After they have f…

Google Rolls Out New Menu in Google Search with Icons

The new search menu now includes icons in addition to regular search category names like News, Images, Shopping, Flights, Videos, and more.
The change was reportedly first seen in March this year when Google was found testing the new look with a limited set of users.

The tweaked Google search page, which seems to have started rolling out broadly earlier today, is now seemingly live for everyone.

Further, Twitter is full of user reports from across the world about the tweaked Google search page.

Search Engine Land was also able to confirm from Google that the new design is indeed live for searchers today.

We have seen reports from UK, Austria, Germany, Latvia, Indonesia, Australia, US, and more.
According to the website, Google has been testing the latest design since March this year.

The latest change doesn't really impact the functioning of the Google Search page and is primary a visual change.

It is unclear why Google has added these icons now as they don't seem to add any value a…

An applet is a small application designed to run within another application.
The term "applet" is sometimes used to describe small programs included with a computer'soperating system, it usually refers to Java applets, or small applications written in the Java programming language.

Java applets cannot be run directly by the operating system. Instead, they must run within the Java Runtime Environment (JRE), or within another program that includes a Java plug-in.

If there is no JRE installed, Java applets will not run. Fortunately, Java is freely available for Windows, Mac, and Linux systems, which means you can easily download and install the appropriate JRE for your system.

Since Java applets run within the JRE and are not executed by the operating system, they are crossplatform, meaning a single applet can run on Windows, Mac, and Linux systems.

Applets can serve as basic desktop applications, they have limited access to system resources and therefore are not ideal for comp…


An algorithm is a set of instructions designed to perform a specific task.
This can be a simple process, such as multiplying two numbers.

Search engines use proprietary algorithms to display the most relevant results from their search index for specific queries.

In computer programming, algorithms are often created as functions. These functions serve as small programs that can be referenced by a larger program.

For example, an image viewing application may include a library of functions that each use a custom algorithm to render different image file formats. An image editing program may contain algorithms designed to process image data.

In many cases, there are multiple ways to perform a specific operation within a software program. Therefore, programmers usually seek to create the most efficient algorithms possible.

By using highly-efficient algorithms, developers can ensure their programs run as fast as possible and use minimal system resources.

Of course, not all algorithms are created …

The TikTok App is Finally back on Google Play Store and App Store

TikTok app is finally back on the Indian versions of the Apple App Store and Google Play after Madras High Court lifted ban on the popular social media app last week.

Earlier this month, the app was delisted from the Indian app stores after the Madurai Bench of the Madras High Court directed the Ministry of Electronics and Information Technology to do so.

The ruling was due to a PIL filed against TikTok stating that the app encouraged pornography and child abuse. The ban was lifted subject to conditions that pornographic videos will not be uploaded on it.

The ban was causing developer, Beijing Bytedance Technology Co, "financial losses" of up to $500,000 (roughly Rs. 3.5 crores) a day and even put more than 250 jobs at risk.

"Banning has had adverse impact on the user base of this app, losing close to 1 million new users per day .

It is estimated that approximately six million requests for downloads could not be effected since the ban came into effect," the company sai…
