Black Box is a device commonly used in the aircraft transportation sector. The function of this Black Box is to record flight data cockpit sound on the plane.

The basic function of the Black Box or black city is to record the pilot’s conversation with the air traffic guide, which is commonly referred to as Air Traffic Control (ATC).

In the following, we will explain what a Black Box or black box is in aircraft transportation.

DEFINITION OF BLACK BOX

The purpose of this object on an aircraft is to control the pilot’s speech and determine the air pressure and weather conditions during the flight.

The color of the Black Box itself is not always black; it is orange. The purpose is called the Black Box, which is to facilitate the search if the plane has an accident.

This black box is usually placed in an easy-to-find area on the plane. There are two units in the black box.

Cockpit Voice Recorder: A tool for recording voice in the pilot’s room.
Flight Data Recorder: A tool for recording flight data.

But at this time, both tools have experienced development. So the two were combined and given the name Combi Box Recorder, which means a combination of voice and data.

Usually, the data for recording is located on a data recorder, usually placed on the tail of the aircraft because the place is a part of the plane that is easy to remove.

The Origin of the Black Box

When a plane crash occurs, often the cause of the incident cannot be determined. This makes an expert explosion expert, Dr. Sona, makes a device that can record all the information and activity on the plane before the crash.

The idea that Dr. Sona was obtained from Australia when she found out that there was a pocket-sized tape recorder there.

Then this tool was designed and developed by him to record the pilot’s voice and all the data received from 8 different devices.

There are also other terms regarding this black box, namely:

Red Egg: Called the Red Egg because of its color and shape, because this recording device is generally not black but orange so that it is easy to find.

Box of Tricks: This term comes from RAF terminology during World War II. During the period of electronic innovation from 1940 to 1945, objects such as the Oboe, GEE, and the H2S were routinely installed on aircraft (usually on bombers).

That’s the understanding of what a Black Box is that maybe you don’t know, Guys! Hopefully, the article above can be helpful and useful for all of you; thank you.

Have you heard of eSIM lately? If you have one, an eSIM is a replacement for a physical SIM card that connects your phone to the cellular network, but an eSIM is much smaller.

The biggest difference between an eSIM and a regular SIM card is that the eSIM is pre-installed on the motherboard of the phone or other device. You don’t need to insert a physical SIM card anymore, and of course, you can’t remove it.

And indirectly this also means that you also can’t change your number or switch to another operator, because the information on the eSIM can be rewritten. It can all be done instantly and easily.

The similarities between an eSIM card and a SIM card are usually the same technology used and run on the same GSM network.

To use an eSIM, you must use an operator that already has the technology and network that can support it and of course, you must have a mobile phone or device that is compatible with eSIM.

Currently, most operators such as AT&T and T-Mobile in the United States have started using this technology, EE operators in the UK, currently, the operator that supports eSIM Smartfren.

Supported Devices with eSIM

In terms of devices that support eSIM, it seems that it is still limited, currently what is supported are devices that can be categorized as high-end devices, including:

iPhones :

The Digit News

In the world of web hosting, Virtual Private Server (VPS) has become a popular choice for website owners who are looking for a flexible and cost-effective solution. A VPS is a virtual machine that is hosted on a physical server, which allows the user to have full control over their server environment, similar to a dedicated server. In this article, we will explain what a Virtual Private Server is, how it works, and its benefits.

What is a Virtual Private Server?

A Virtual Private Server is a virtual machine that is created on a physical server, which is partitioned into multiple smaller virtual servers. Each virtual server is isolated from one another, and the user is provided with complete root access to the operating system, which means the user can install any software or application they want, as long as it is compatible with the operating system.

A VPS is a combination of shared hosting and dedicated hosting. It provides the user with a dedicated operating system, which means that the user can install their applications and software without affecting other virtual servers hosted on the same physical server.

How does a Virtual Private Server work?

A VPS works by virtualizing the physical server, which means that it creates a virtual environment on top of the existing hardware. The virtualization software creates multiple virtual servers that are independent of one another, and the user is given full access to the operating system.

The virtualization software used in VPS hosting is called hypervisor. The hypervisor is responsible for creating and managing the virtual servers. It creates a virtual machine for each user, which is isolated from other virtual machines. This ensures that the user has complete control over their environment and that they are not affected by other users on the same physical server.

Benefits of a Virtual Private Server

There are several benefits of using a VPS, including:

Cost-effective

A VPS is a cost-effective solution compared to a dedicated server. The user can get the benefits of a dedicated server at a lower cost.

Scalability

A VPS is scalable, which means that the user can increase or decrease their resources as per their requirements. The user can upgrade their resources as their website grows, which ensures that they do not have to pay for resources they do not need.

Control

A VPS provides the user with complete control over their environment, which means that they can install any software or application they want.

Security

A VPS is more secure than shared hosting as the user has complete control over their environment. They can install security software and customize the server settings to enhance security.

Reliability

A VPS is more reliable than shared hosting as the user is not affected by other users on the same physical server. The user can customize their server settings to ensure maximum uptime.

Steps to set up a Virtual Private Server

Setting up a VPS is a straightforward process. Here are the steps to set up a VPS:

Step 1: Choose a VPS provider

The first step is to choose a VPS provider. There are many VPS providers in the market, and the user should choose the one that best fits their requirements.

Step 2: Choose the operating system

The user should choose the operating system they want to use. The most popular operating systems used in VPS hosting are Linux and Windows.

Step 3: Choose the resources

The user should choose the resources they want to allocate to their virtual machine. The resources include CPU, RAM, and storage.

Step 4: Configure the VPS

Once the user has chosen their resources, they should configure their VPS. The user should customize their server settings to ensure maximum uptime and security.

Step 5: Install applications

The user can now install any application or software they want on their virtual machine.
