When it comes to good internet connection, we always want what is fastest. Although wireless connection is currently the more popular option, the fastest connection is still acheived with cables, ethernet cables to be exact. It is a proven fact that a connection through an ethernet cable is faster than a WiFi connection. The differences don’t really matter to people who use their laptops or desktop computers for social media only. However, when it comes to gaming, transferring files, and streaming movies and TV series, there is a huge difference to the speed of the connection. This is because WiFi connection can be disrupted by walls and floors, which means that being in a different room may result in not being able to connect.

Personally, I have had a lot of trouble with my WiFi connection before I decided to buy ethernet cables online. I live in a two storey house where the router is on the first floor, while my man cave is on the second one. I have it equipped with all kinds of gaming equipment, from my gaming PC to the PlayStation that I often use to play with a few buddies. However, there was always the problem of bad connection. My games would lag which meant that I couldn’t play properly, and whenever I sat down to watch a movie, it would take forever to load. As I had my router directly below my setup, I thought that I was getting the fastest connection I could possibly get in my house. I always figured that this was the fault of my internet provider, but now I know that wasn’t the case. When I switched to cables, I felt the difference immediately.

If you too are considering to switch your connection method, and buy ethernet cables online, you need to bare in mind that there are few types. There are Cat5, Cat5e and Cat6. The acronyms stand for category 5 cabling, category 5 enhanced cabling, and category 6 cabling. The Cat5 are the oldest and they support the speed of 10Mbps and 100Mbps. However, since they are really old, you can’t find them in stores anymore. Cat5e, as the name suggests, is an enhanced version of the older Cat5. These cables support 100Mbps speeds, which are also known as gigabit speeds. Normally, the best is saved for last – the Cat6 is yet a better version of Cat5e. It supports 10-Gigabit speed and there are a lot of improvements made so that there wouldn’t be any interference. However, you should note that if you’re currently experiencing a rather stable connection you don’t need to rush things in order to get the Cat6, but if you are upgrading, you might need to.

According to a research done in 1950 by the psychologist George Miller, human beings have the capacity to remember approximately seven numbers at a time. This study also revealed that even our ancestors have been using different calculating tools, such as “abacus” (today calculators) to help them calculate.

The term ‘calculator’ is derived from the Latin word “calculare”, meaning to calculate something by using stones. First editions of mechanical calculators were widely used from the late 19th up to the late 20th century. Generally, calculators and computers have many things in common, however, calculators are human-operated machines, while computers are programmed for an automatic performance.

Before buying calculator for the first time, let’s take a look at some of the basics and the working principle.

The Inside of a Calculator 

• Input: Keyboard membrane with around 40 plastic keys and a touch-sensitive circuit underneath;
• Processor: Microchip that is in charge of all the hard work;
• Output: LCD (Liquid Crystal Display) for showing the typed numbers and obtained results;
• Power Source: Battery or solar cell.

How Plastic Keys and Keyboard Work?

By pressing a plastic key, the rubber membrane underneath the key make an electrical contact between the two layers in the keyboard sensor, which is automatically detected by the keyboard circuit. The microchip recognizes the number that has been pressed and activates the right segments on the display corresponding to the pressed number.

How Does the Display Work? 

Computer screens make numbers and letters using pixels (tiny grid of dots). The truth is, modern calculators are still “stuck” in the early ages (1970s). If you take a closer look at the calculator display, you will notice that each digit is made of different pattern of seven segments or bars. The microchip knows that it can display any of the numbers (0-9) by activating various combinations of these seven segments.

How Does the Calculator Add Тwo Numbers Together? 

Numbers In Binary 

The process of adding two numbers together involves representing decimal numbers in different format, “binary” and comparing them with electrical circuits, also known as “logic gates”.

For example, if you want to write 19, you press the numbers 1 and 9 written together as 19. This means 1×10 plus 9×1 = 19. This is an example of how decimal works using a system of ten symbols. Both calculators and computers, process and store the numbers by using a binary code with only two symbols (0 and 1) in order to represent any number. Consequently, in binary code, the number 19 is written 10011 or (1×16) + (0x4) + (0x8) + (1×2) + (1×1) = 19.

Logic Gates With Binary

Logic gates represent a simple electrical circuit that compares two numbers in order to produce a third number, known as “output”. There are three common types of logic gates:

• OR – it has two inputs and can produce an output of 1 (only if one of the inputs is 1);
• AND – it has two inputs and can produce an output of 1 (only if both inputs are 1);
• NOT – it has only one input that it reverses it in order to make an output.

Nowadays calculators come in wide range of different models, which practically means that there are many features to consider before buying calculator. The final word will be determined by your personal needs and of course, the budget.

The digital interface is carried out in digital format, making the conversion unnecessary. Available in two different types – standard and high speed type, the HDMI cable offers many advantages. Read on to explore the benefits of the HDMI cable:

The HDMI cable allows various digital devices to be connected together much easier. One single HDMI cable has the capacity to replace several cables. With this cable, connecting and upgrading an entertaining system is much easier.

Pure digital performance. The HDMI cable transmits uncompressed audio-video data in 100 percent digital format. That provides an increased viewing experience with a great video accuracy and audiophile quality sound.

Authentication and encryption: The HDMI cable supports authentication. This ensures authorization for receiving the content sent by the HDMI enabled sources. Moreover, it allows authentication by ensuring that people cannot tap into the cables to copy the content sent through them.

Signal integrity. The HDMI cable enables digital signals to be stored, transmitted and viewed without any interference from other digital devices.

No compression. With a HDMI cable, there is no degradation in the signal quality. That’s because the HD signals are not compressed during the transmission.

Supports multiple video and audio formats. The HDMI cable supports multiple audio and video formats, such as standard stereo, multi channel surround sound, etc.

Compatibility with DVI. Since a HDMI cable allows DVI interface, it enables PC’s to send HD content to other digital devices.

Nowadays, HDMI is the standard cable for connecting HD equipment. Today, every HD television, DVR, Blu-ray disc player, etc, comes with at lest one HDMI output. Also, PC’s, laptops, gaming consoles, mobile devices and many other products, enable HDMI connection, giving you a bunch of choices for watching or listening HD content.
