What is the difference between Wired Networks and Wireless Network? Which one is better?
A wired network uses Ethernet wires to get connected to the computers unlike the wireless network that uses radio waves to connect to the computer and other devices. Both types of networks have their flaws just like anything else. The wired network is less expensive, more secure, and faster but the con of the wired network is that to be connected to it you must always be connected to the Ethernet wire which can be a struggle having to have cables connected all the time. A wireless network doesn't consist of wires and uses radio waves to send and receive data. Wireless networks aren't as secure or as fast as the wired network but you are able to get connected to it within in the range of your wireless router. |

Blue tooth technology started around 1998 when the idea and the name was adopted. Blue tooth technology is a wireless communication technology. Blue tooth is found in many different devices like cellphones, computers, medical devices and home entertainment devices as well. Bluetooth is can be wherever you need it, its low cost and doesn't take much to power it. Blue tooth is defined as a wireless communication technology that can exchange data over certain distances. Having blue tooth gives a person a personal secure exchanging device.
 Network Cables
What is a Network Cable and what is it used for? Network cables are the medium where data is being sent through and received through. There are 3 main common network cables. There is the Coaxial cable, Unshielded twisted pair (UTP) cable, and the fiber optic cable. The Coaxial cable is used for audio and visuals. For example a coaxial cable is used for TVs and VCRS. The UTP cable is used for telecommunications and computer networks. The fiber optic cable is becoming a famous replacement for the simple copper wire but the fiber optic cable is better than the original copper wire because it is able to carry a larger amount of bandwidth over a longer distance and it's also faster than the copper wire. There are many more types of network cables but the 3 main cables are the UTP cable, the Coaxial cable, and fiber optic are the three main of network cables.
 Input Devices & Output Devices
Whats the difference between an input device and a output device? An input device is a hardware device that sends data to a computer without having to use an input. An output device is a device that displays or outputs anything from a computer. An example of an output device is a printer and an example of a input device is a mouse or a keyboard.

CPU
What is CPU and what does it do?
CPU stand for Central Processing Unit. The name sort of speaks for itself. The CPU is the place where most calculations of a computer are being made. The CPU is found in the inside of a computer and the modern CPUs are usually small and square.
 RAM
RAM is short for Random Access Memory, but what does Ram do and what is it? RAM is a type of computer memory. RAM differs from other computer memories because it can be randomly accessed. By randomly accessed I mean any byte of memory can be reached without having to touch the preceding bytes. RAM is one of the most common memory in computer devices.

ROM
ROM is short for Read-Only Memory and is also known as firmware. ROM or firmware is a integrated circuit that is programmed with specific data when made, you can find ROMs in computers but not only computers, you can find them in other electronic devices.
 Operating Software
What is an operating software? An operating software is a type of system software that is able to communicate with the hardware. Operating software allows programs to run. Some examples of an operating software are Windows and Mac OS X.

Application Software
An application software is a program or a group of programs that is especially designed for the owner of the final product. Application software is divided into two types. Systems software and Applications software. Application software are things like word processors, spreadsheets, web browsers,
Charles Babbage
Who is Charles Babbage? What did Charles Babbage do? Charles Babbage was born December 26, 1791. He was born in London. In 1821 Charles Babbage invented the Difference Engine to produce mathematical tables. He finished it in 1832. Soon he tried to to create something that would do all types of calculations, which became the Analytical Engine in 1856. Some of the characteristics of the analytical engine are still found in some of today's computers.
 Lady Lovelace (Lady Byron)
Lady Byron also known as Lady Lovelace was born in December 10, 1815. When Lady Lovelace was 17 she met Charles Babbage and later on he became her mentor and good partner. She soon went to the University of London to study advanced mathematics. She soon heard about Babbage's invention and loved it but it wasn't enough. She was asked to translate an article that was in French to English on Babbages analytical engine, which she did but she also added her own thoughts to the article. She explained how codes could be made for devices to handle letters and symbols and numbers. She also explained a method for an engine to repeat instructions, which we still use today, which is known as looping.

Grace Hopper & ARPAnet
Grace was a United States Navy rear admiral, but she was also a computer scientist. Grace Hopper was the person who invented the modern compiler. The modern compiler is what takes written text and turns it into a code that a computer can run. Grace Hopper is also known for the word "debugging", by debugging she meant finding and fixing glitches in computers. The ARPAnet is was one of the first operational packing switching networks and Grace Hopper was one of the people who first were able to program on it. The ARPAnet was the progenitor of what was soon to be the Internet.
 World Wide Web History
The idea of the world wide web goes back all the way back to 1964. The world wide web is a system on the Internet that lest documents to be connected to other documents using hyperlinks.
