host controller used which is USB 2.0 full speed. Theoretically, if the host microcontroller used follows the USB 2.0 high speed standard, the speed of data transfer should be much faster than the computer since there is no associated overhead in the bus compared to the computer. The main objective of this study is to develop a device that can transfer files from flash drive to flash drive. Specific objectives include the following to create an interface that will list all the file/s or folder/s in
will make life and businesses easier and more successful. BUS TECHNOLOGY 4. At one time, "bus" (Annex 1-a) meant an electrically parallel system, with electrical conductors similar or identical to the pins on the CPU. This is no longer the case, and modern systems are blurring the lines between buses and networks. 5. Buses can be parallel buses, which carry data words in parallel on multiple wires, or serial buses, which carry data in bit-serial form. The addition of extra power and control connections
hardware components at a steady temperature to allow continuous processing. USB Ports Universal Serial Bus (USB) is a device that allows communication between other devices and a host such as computers. USB has effectively replaced the previous removable devices such as the floppy disk which was used to save and transfer files from one computer to another. They are a variety of interfaces such as serial and parallel ports. Sam will need to use USB compatible devices such as mice, keyboards, digital

The printer on the left is an INK JET PRINTER, and the other is a LASER PRINTER. | . | . | Hub | | | ------------------------------------------------- Hubs are devices that have many ports into which network cables are plugged. A hub takes the signal from each computer and sends it to all of the other computers through the network. Hubs come in different sizes and colors. The hub must be plugged in and turned on for the network to
may also jump across the screen for no reason. To clean a mouse is fairly straightforward, it only takes about ten minutes so lets get started. * The first step is to unplug your mouse. Optical mice usually connect to the computer via the USB port. If you have a USB mouse, then you can remove it without switching off the computer. If however, your mouse connects using different connectors, then you should switch your computer off first. * Once unplugged, look at the bottom of the mouse to
divided into three 8-bit ports, one 6-bit port and one 3-bit port .Three 8-bit ports designed as PORTB, PORTC and PORTD. One 6-bit port designed as PORTA. One 3-bit port designed as PORTE. HARVARD ARCHITECTURE: In the HARVARD ARCHITECTURE, the memory is split into two part .One Part for data memory and another part for instructions (program) memory. Each part is accessed by different bus (data memory is accesses by data bus and instructions memory is accesses by program bus). In the Harvard Architecture
transmissions, parallel and serial. Digital data transmission can occur in two basic modes: serial or parallel. Data within a computer system is transmitted by parallel mode on buses with the width of the parallel bus matched to the word size of the computer system. Data between computer systems is usually transmitted in bit serial mode. It is necessary to make a parallel-to-serial conversion at a computer interface when sending data from a computer system into a network and a serial-to-parallel conversion
logging service and user interface seems the most logical solution. Separating the GUI and the logger would allow for the KNX bus to be logged with a background process, rather than require an application to be running in the foreground when logging. Figure 2.3-1 illustrates the overall solution proposed in this section. The diagram shows the KNX network, the KNX to serial module, the host server, the logging service, the database, the user interface and finally the user; it illustrates how these
