Recommended: History of Universal Serial Bus
Universal Serial Bus (USB) is the system used for connecting peripheral devices to personal computers by means of standard connections and communication systems. It was developed during January 1996 by a cluster of companies such as the Intel, Compaq, Microsoft, Digital IBM, and Northern Telecom. These companies also formed the USB Implementation Forum Inc. (USB-IF) which is a nonprofit organization publishing the specifications of the technology and giving them support for further development and adoption of the USB technology. It is developed to replace the different kinds of parallel and serial ports on a computer by providing an additional peripheral device which is quick and easy to use for the users.
Universal Serial Bus is also being used to connect different peripheral devices to your personal computer like the keyboards, printers, digital cameras, media players, internal hard drives and flash drives. It is also the reason it became a standard mode of connectivity. First it was designed just for personal computers but as time passed it has been an option for devices like...
A bus is a communication system that connects multiple subsystems within a computer. An average computer system normally consists of several components such as a central processing unit, memory devices, and input/output (I/O) devices. The bus system consists of linking media like wires and connectors, and a bus protocol. Buses can be categorized as serial or parallel and synchronous or asynchronous. The bus lets the different components communicate with each other by allowing information to flow between units and devices.
A Hub is a networking device that allows one to connect multiple PCs to a single network. Hubs may be based on Ethernet, Firewire, or USB connections. “A switch is a control unit that turns the flow of electricity on or off in a circuit. It may also be used to route information patterns in streaming electronic data sent over networks. “
It just doesn't get much simpler than the physical bus topology when it comes to connecting nodes on a Local Area Network (LAN). The most common implementation of a linear bus topology is IEEE 802.3 Ethernet. All devices in a bus topology are connected to a single cable called the bus, backbone, or ether. The transmission medium has a physical beginning and an end. All connections must be terminated with a resistor to keep data transmissions from being mistaken as network traffic. The terminating resistor must match the impedance of the cable.
USB ports are developed to connect keyboard, mouse, printer and many other devices to the PC. They are developed in mid1990’s and gains a tremendous success because no additional knowledge is required to install the devices. USB ports not only communicate between devices and computer but it can also supply electric power to the devices. USB ports are not only limited to computers but it can also be seen mobile phones and video games consoles. USB ports has undergone a lot of advancement since its development in 90’s. It is now available in three different speeds. They are best known for plug and play in the 20th century. It can be attached and detach from the pc without switching it off. They are standardized by group
It all began in 1991, during the time of monumental computing development. DOS had been bought from a Seattle hacker by Bill Gates, for a sum of $50,000 – a small price for an operating system that had managed sneak its way across the globe due to a clever marketing strategy. Apple’s OS and UNIX were both available, though the cost of running either was far greater than that of running DOS. Enter MINIX, an operating system developed from the ground up by Andrew S. Tanenbaum, a college professor. MINIX was part of a lesson plan used to teach students the inner-workings of an operating system. Tanenbaum had written a book on MINIX called “Operating System” and anyone who had picked up a copy would find the 12,000 lines of code that comprised MINIX itself. This was a big issue; due to the fact that all know (well published) operating systems to that point had been well guarded by software developers, thus making it difficult for people to truly expand on operating system mechanics.
This motherboard has Universal Serial Bus (USB) 2.0. This gives the advantage of high-speed transfer between external sources such as video cameras, digital cameras, scanners, audio recorders, and any other possible external components. USB 2.0 is faster than fire wire, which is currently the most widely used transfer hardware.
2. To transfer files from one computer to another (the files may be text, images, audio, video, etc.).
At the outset, before the advent of user friendly operating systems, computers were run using the operating system CP/M (Control Program for Microcomputers). The program itself looked simple, but the complexity of its use meant that not many fully understood how to use it. As the program was also limited in use, since it was designed for 8-bit systems, a new operating system was needed when 16-bit IBM systems came out.
Terminal Operating Systems often utilize other technologies such as internet, EDI processing, mobile computers, wireless LANs and Radio-frequency identification (RFID) to efficiently monitor the flow of products in, out and around the terminal. Data is either a batch synchronization with, or a real-time wireless transmission to a central database. The database can then provide useful reports about the status of goods, locations and machines in the terminal. The objective of a Terminal Operating System is to provide a set of computerized procedures to manage cargo, machines and people within the facility to enable a seamless link to efficiently and effectively manage the facility. Terminal operating systems can be stand-alone systems, managed as a service or
The UML was released in 1997 as a method to diagram software design, by some of the best minds in object oriented analysis and design. It is by far the most exciting thing to happen to the software industry in recent years. Every other engineering discipline has a standard method of documentation. Electronic engineers have schematic diagrams; architects and mechanical engineers have blueprints and mechanical diagrams. The software industry now has UML.
Abilities and services which can access through basic mechanisms that promote use by heterogeneous client platforms like smartphone, laptop, or even other devices.
One of the latest advancements in wireless data. It is used in GSM (Global System for Mobile Communications) for transferring data in packets.
There is a brand new Device Manager that, combined with its plug and play hardware detection and large list of supported hardware, makes it a huge improvement over NT in overall hardware compatibility. New hardware supported it Windows 2000: Accelerated Graphics Port (AGP), DVD, FireWire (IEEE 1394), USB Devices, Advanced Configurable Power Interface (ACPI), Multiple monitors, etc.
In 500 B.C. the abacus was first used by the Babylonians as an aid to simple arithmetic. In 1623 Wihelm Schickard (1592 - 1635) invented a "Calculating Clock". This mechanical machine could add and subtract up to 6 digit numbers, and warned of an overflow by ringing a bell. J. H. Mueller comes up with the idea of the "difference engine", in 1786. This calculator could tabulate values of a polynomial. Muellers attempt to raise funds fails and the project was forgotten. Scheutz and his son Edward produced a 3rd order difference engine with a printer in 1843 and their government agreed to fund their next project.
Thousands of years ago calculations were done using people’s fingers and pebbles that were found just lying around. Technology has transformed so much that today the most complicated computations are done within seconds. Human dependency on computers is increasing everyday. Just think how hard it would be to live a week without a computer. We owe the advancements of computers and other such electronic devices to the intelligence of men of the past.
