Conyers Cloud 2021

Windows 7, Vista and XP computers connected to the internet or used for email are sometimes bit by a computer virus, mal-ware or scare-ware that comes from a web-site we should not have visited or an email from an associates computer that was used by a virus on their end. Conyers virus removal is available from proven IT professionals that are better than the in-experienced high-school graduates sent out by the national brand names. Also watch out for a low monthly price when by the end of the contract you will pay three times the cost of fixing your PC.

We also handle PC upgrades for Conyers and especially cover areas within ten miles of the Conyers city limits. We also handle remote access technical support which allows us to offer our services without charging you for the trip cost and time. We are especially appreciated by our repeat customers that use us to remotely install printer software, assist with proposal and estimate templates and PC tune-ups. We also perform memory upgrades and things like that cannot be handled remotely.

But the service our clients like the most is our regular reviews and updates of anti-virus and anti-spyware solutions. We offer remote assistance cleanout of your expensive and cumbersome solutions with the Avira virus solution that costs less than $ 30 per year plus our virus update charge of $ 60. We additionally recommend the use of Malware bytes for scans when problems occur, and can teach you how to boot into safe mode for scanning before a virus can do more serious damage.

Transformers

As the story goes, the great Nikola Tesla, who worked for Thomas Edison for a time, ushered in modern electricity by inventing a system of alternating current that was completely different from the vision of Thomas Edison, and completely new to the world.

But the truth is that the electric generator, the foundation of the revolution of abundant electrical power, had already evolved in two forms, the direct current and the alternating current form.

The electric generator was pioneered by Michael Faraday around 1832. It operates by overpowering mysterious magnetic forces. The power input into the system to overpower the magnets gets translated into a flow of electrons, that can be captured by a battery, or sent down wires to run a motor or heat something.

Faraday used a rotating disk and a fixed horseshoe magnet, he captured the electrons with a springy piece of metal along the edge of the disk, which rotated on an axle where the electrons returned.

The Faraday disk generator produced an alternating current as the poles of the magnet alternated from north to south relative to the rotating disk.

Years later, the generator was improved to provide direct current by using a commutator, a gimmick that switched the polarity of the outputs at 180 degree points of rotation.

But over time we learned that the losses from transmitting alternating current over wires were far lower, and the direct current generator is now very rare. Even a cars alternator produces alternating current, but they are packaged with a rectifier and a regulator.

The Transformer

You might be aware that there is probably a transformer on an electrical pole not far from your house. But do not forget the every iPhone charger and laptop battery charger is also a transformer. The modern sophisticated electrical grid would not be possible without transformers.

Faraday also deserves a lot of credit for the transformer, as he used mathematics to describe how magnetic forces and alternating currents effected the flow of electrons.

Faraday was not alone discovering the effects of magnetic forces on themselves and other things, but he was probably the best theoretical mathematician in his field and at the time. In 1831, another scientist, Joseph Henry, was documenting similar findings. Faraday was in England and Henry was in America.

So what did Nikola Tesla invent?

Nothing really, most of his hands on experiments were utter failures. But he was probably aware of the works of Galileo Ferraris and Mikhail Dolivo-Dobrovolsky. He might have noticed that John Hopkinson received a British patent for three phase electrical transmission and distribution in 1882.

Tesla was crazy, but brilliant, and he could read the math and understand the phases and sines and cosines. More so, Tesla envisioned the problems and solutions. Westinghouse was the hands on guy that turned Niagara Falls into a revolution, but certainly Nikola Tesla helped Westinghouse to see why three phase alternating current was the winning way to transform the nation.

Tesla was correct in one thing, he recognized how cool alternating current and three phase electricity was, all while Edison was still trying to charge a battery.

Raw Sockets

Socket programming is a specialized area of network programming. While it offers the richest capability by its nature, it is little used due to the amount of intellectual overhead required to manage all the settings of the IP packet.

Visual Basic is one tool that makes socket programming easier with DLL library support, but yields an application that is limited to Windows and may require specific versions of windows.

C programming is another option, yielding a result that also ties to windows DLL libraries, but with an abstraction layer can in theory be written platform agnostic. Firstly the program which opens and closes a TCP socket.

The use of sockets allows complete control of ip address, port, packet size, et. al.

#include
#include

WSAStartup initializes the sockets processes.

UDP

A program can listen on UDP port 80, and use any data received on that port. UDP does not use a connection like TCP, once established, it never closes.

#include
#include

for printf main() {
WSADATA ws;
WSAStartup(0x0101,&ws);
SOCKET udp_socket;
struct sockaddr_in peer;
int peerlen;
char recvbuffer[20];
int retval;
peer.sin_family = AF_INET;
peer.sin_port = htons(80);
peer.sin_addr.s_addr = htonl(INADDR_ANY);
udp_socket = socket(AF_INET, SOCK_DGRAM, 0);

raw sockets allow you access to any parameter in an IP or TCP header.
