Raspberry pi

  What is a raspberry pi?

Raspberry Pi is the name given to single board computers built by the Raspberry Pi Foundation, a UK charity that works to educate people in computing and make computer education accessible.

Raspberry Pi was launched in 2012 and since then several iterations and variations have been published. The original Pi had a single-core 700MHz CPU and only 256MB of RAM, and the latest model has a quad-core 1.4GHz CPU with 1GB of RAM. The original price point of the Raspberry Pi is always $ 35 and all models including Pie Zero are $ 35 or less, priced at just $5.

Around the world, people use raspberry pieces to learn programming skills, create hardware projects, do home automation, and even use them in industrial applications.

Raspberry Pi is a very inexpensive computer that runs Linux, but it provides a set of GPIO (General Purpose Input / Output) pins that allow you to control electronic components for physical computing and explore the Internet of Things (IoT).

What raspberry pi models have been published?

There are three generations of raspberry pieces: Pi 1, Pi 2 and Pi 3 and usually most generations have a Model A and a Model B. A cheaper variant in the model and can reduce RAM and ports like USB and Ethernet. The Pi Zero is a spin-off of the original (Pi1) generation, making it even smaller and cheaper.

Model (date of publication) Price

Pi1 Model B (2012) $ 35

Pi 1 Model A (2013) $ 25

Pi 1 Model B + (2014) $ 35

Pi 1 Model A + (2014) $ 20

Pi 2 Model B (2015) $ 35

Pi Zero (2015) $ 35

Pi 3 Model B (2016) $ 35

Pi Zero W (2017) $ 35

Pi 3 Model B + (2018) $ 35

Pi 3 Model A + (2019) $ 25

What is the Raspberry Pi Foundation?

The Raspberry Pi Foundation works to keep the power of computers and digital creation around the world. It does this by providing low-cost, high-performance computers for people to learn, solve problems and have fun. It provides outreach and education to help more people gain access to computers and digital creation - it develops free resources to learn how to make and learn things on computers through computers, and trains other trainees who can guide other people to learn.

Code Club and Codardojo are part of the Raspberry Pi Foundation, although these programs are platform-agonistic (not tied to Raspberry Pi hardware). Raspberry Pi promotes these clubs and helps expand the network around the world to ensure access to every education on the computer. Similarly, raspberry jams are raspberry pie-centric events where people of all ages come together to learn about raspberry pie and share ideas and projects.

Raspberry pi open source?

Raspberry Pi works on the open source ecosystem: it runs Linux (a variety of distributions), and its main supported operating system Raspberry runs a suite of open source and open source software. The Raspberry Pi Foundation contributes to the Linux kernel and various other open source projects, as well as publishing most of its own software as open source.

The schematics of Raspberry Pi have been published but the board itself is not open hardware. The Raspberry Pi Foundation's charitable work depends on income from the sale of raspberry pi's.

What can you do with a raspberry pi?

Some people buy a raspberry pi to learn the code and people who can already apply the code use the pie to learn electronics code for physical projects. Raspberry Pi can open up opportunities to create your own home automation projects, which are popular with people in the open source community because it keeps you in control without using a proprietary closed system.

Making a physical product with raspberry pi

Here are some projects you can tackle with raspberry pi:

Block ads on your network with pi-holes

Set up a postgrass database on a raspberry pie

Bot your own Twitter with Python and Raspberry Pi

Create projects using the Raspberry Pi camera

Set up WordPress on a raspberry pi

why is upload and download speed different?

 Upload vs. download speed: What’s the difference?

How the speed of the internet works?

Internet speed is measured by how much data your Internet connection can transfer per second, which is megabytes of data per second (Mbps). Internet data providers in your home and your home measure the Internet speed you see in Mbps at a provider (commonly known as download speeds).

Data also goes in two directions - you download and upload data from the Internet, so each Internet connection will have download speeds and upload speeds.

What is the download speed?

Download speed refers to how many megabytes of data per second it takes to download data from a server in the form of images, videos, text, files, and audio. You need to download data for activities like listening to music on Spotify, downloading large files or streaming videos to Netflix.

What is a good download speed?

Generally, speeds of at least 25 Mbps are considered good download speeds because they meet the minimum broadband threshold set by the Federal Communications Commission (FCC). Keep in mind that for your home, the number of devices for Internet users and their online activities can change what is considered a good download speed for your family.

What is the upload speed?

Upload speed refers to how many megabytes of data per computer you can send from your computer to any other device or server on the Internet. While data download time is seen as normal, some online activities require data to travel in the opposite direction. You need fast upload speeds to send emails, play live tournament-style video games, and send data to someone else's server to call a friend.

What is a good upload speed?

Again, in general, upstream speeds of 3 Mbps are considered good upload speeds because they meet the FCC minimum standards. If you or someone in your family regularly uploads videos to YouTube or works from home, you may need a plan for higher upload speeds.

What is Internet Bandwidth?

Bandwidth is the slower the highway you have, the more lanes you have, the more cars you will give to travel cars, which allows cars to go faster and more cars to reach their destination.

Mbps is a good indicator of how much bandwidth your home Wi-Fi connection has. The more internet bandwidth you have, the faster your data volume can be downloaded. And you can increase the speed at which data travels because it can flow more.

So what kind of bandwidth do you need?

When you consider Internet speeds for different activities, you should consider both download and upload speeds. Depending on what your favorite online activities may be, one may be more important than the other.

Download speed vs. upload speed

Many internet providers offer internet plans with faster download speeds than uploads. For example, there may be a 400 Mbps difference between download speed vs. upload and download speed.

Which has the fastest upload and download speeds

The internet speed you need depends on your online activities and how many internet users you have in your home.

As you think about what activities you use the Internet for at home, you may decide that having a faster upload speed is more important than download speeds. You see, you don't really need a fast upload speed and just want a fast download speed that can handle streaming on the device.

Provider Internet download and upload speeds

Provider download speeds increase upload speeds

It and TSL 25 Mbps 5 Mbps

AT&T DSL 75 Mbps 20 Mbps

AT&T DSL 100 Mbps 20 Mbps

AT&T DSL 500 Mbps 100 Mbps

AT&T Fiber 50 Mbps 50 Mbps

AT&T Fiber 100 Mbps 100 Mbps

AT&T Fiber 300 Mbps 300 Mbps

It & T Fiber 1,000 Mbps 1,000 Mbps

Why internet upload speed is slow and download speed is fast

Most online activities focus on download speeds versus upload speeds because most online activities require more download bandwidth than upload bandwidth. As you can see below, most common online activities rely heavily on fast download speeds.

Since the data that calls for uploading other activities still requires the information needed to travel in both directions, the average person needs consistently higher download speeds than uploads.

However fiber internet connection is a unique exception. Fiber Internet providers often offer upload internet speeds that mirror download speeds.

Download vs. Download: When download speed is important

The following common actions depend heavily on download speeds:

Watching Netflix movies or shows

Shopping online

Scrolling through social media

Watching youtube videos

How to enable Wi-Fi on a laptop

Wi-Fi can be enabled by performing any of the steps below.

Laptop wi-fi buttons

Enable with laptop Wi-Fi button

Some laptops have an On/Off button or switch for the Wi-Fi connection, like the button shown in the picture. It is usually found on the front edge of the laptop or above the keyboard. Find the button or switch and make sure it is enabled. When enabled, the button should be illuminated as blue, or the switch should be in the On position.

Enable with laptop Fn and function key

Some laptops enable and disable Wi-Fi using the Fn key and one of the function keys (F1-F12). As seen in the picture, some laptops use Fn and F12 key to enable and disable Wi-Fi and shows an orange LED when disabled and blue when enabled.

Enable Wi-Fi in Windows

Look in the Windows notification area to find the icon for Wi-Fi or wireless Internet. Right-click with your mouse on the icon and select the option for enabling (or turning off) the Wi-Fi device in the pop-up menu. If no Enable option is available in the pop-up menu, there may be an option called Open Network and Sharing Center. If so, select this option and then select Change adapter settings. Once the icon for the wireless network card is seen, right-click it and select Enable.

Note

In Windows 8, when you right-click the Wi-Fi icon, check to see if Airplane Mode is turned on. If it's, turn it off to enable the wireless network card.

The Wi-Fi adapter can also be enabled in the Control Panel, click the Network and Sharing Center option, then click the Change adapter settings link in the left navigation pane. Right-click the Wi-Fi adapter and select Enable.

Enable Wi-Fi in Windows Device Manager

Access the Device Manager by right-clicking with your mouse on the My Computer icon on your desktop or in the Windows Start menu. Select Properties from the pop-up menu, click the Hardware tab in the window that opens up, and click the Device Manager button.

Note

In Windows Vista and later, there is no Hardware tab. Click the Device Manager link in the System window.

Find the Wi-Fi adapter in the list of hardware devices. Right-click the adapter name and select Enable from the pop-up menu. If no Wi-Fi adapter is found in Device Manager, the Wi-Fi adapter drivers are not installed.

Enable Wi-Fi in BIOS setup

Finally, there is also the option of enabling the Wi-Fi device in the computer's BIOS setup. However, it is very unlikely that the Wi-Fi device would be disabled in BIOS.

Disable in BIOS setup

As is the case with enabling the Wi-Fi device, it can also be disabled in the computer's BIOS setup.

How to enter the BIOS or CMOS setup.

Wi-Fi on desktop computers

Wi-Fi adapters are also available for desktop computers. The Wi-Fi button mentioned above is not available with most desktop computers. However, there is the possibility that the Wi-Fi adapter itself (e.g., an external version, like a USB Wi-Fi adapter) has an On/Off button or switch. If there is no button or witch, disconnecting the adapter from the computer disables the device.

If the Wi-Fi adapter is not an external device, it is either an internal PCI expansion card or built onto the motherboard. When you install the software for the Wi-Fi adapter, an icon will then show in the Windows notification area, giving you access to enable and disable the device. Alternatively, you can disable and enable the Wi-Fi adapter through the Device Manager or the BIOS.
