What is sod and Sid in microprocessor?
Answer: SID (Serial input data line): It is an input line through which the microprocessor accepts serial data. SOD (Serial output data line): It is an output line through which the microprocessor sends output serial data.
What is serial I O control?
Practically every electronic product made today uses one or more serial data interfaces. A serial interface is the fastest and easiest way to get data into or out of a device.
What does serial input output mean?
serial input/output (SIO) A method of communicating data between devices, typically a computer and its peripherals, the individual data bits being sent sequentially. Asynchronous methods are generally used with dial-up modems or for general connection of simple serial peripherals.
Why do we use serial communication?
Serial communication is used for all long-haul communication and most computer networks, where the cost of cable and synchronization difficulties make parallel communication impractical.
What is the limitation of serial communication?
Drawbacks or disadvantages of Serial Interface ➨It uses less number of lines for transmission between devices. Hence it supports slower speed of transmission. ➨It occupies overhead of about 20% other than useful information. This leads to wastage of bandwidth meant for data trasmission for useless stuff.
What are two advantages and one disadvantage of using serial ports?
Serial mode offers the advantage of fewer traces on the pc board, and fewer pins on the devices. Parallel offers the advantage of transferring 8 data bits per I/O clock cycle, but at the disadvantage of many more pins required on the devices.
Is TCP IP serial or parallel?
The concept is very similar to any other type of port on your PC (serial, parallel, etc) except that instead of having a physical connection, the TCP/IP protocol creates a “virtual IP port” and the network hardware and software is responsible for routing data in and out of each virtual IP port.
Is USB serial or parallel?
USB is supported at the operating system level. Compared to alternative ports such as parallel or serial, USB is very user-friendly. Today, every PC comes with Universal Serial Bus, or USB ports. In fact, many computers will even have USB ports located on the front of the tower, in additional to USB ports at the back.
Is parallel or serial faster?
When data is sent using parallel data transmission, multiple data bits are transmitted over multiple channels at the same time. This means that data can be sent much faster than using serial transmission methods.
Why is USB faster than serial?
USB allows data to travel on the average of ten times the speed of the normal parallel port. It is also faster than a serial port. The average serial port transfer rate is 150 kbps; the USB port is up to 12 Mbps. That means that if a new computer comes with USB 2, the older USB devices may still be used.
Is USB actually serial?
USB is a serial protocol. In case the USB device has to handle parallel data, then that data is serialized and transmitted and de-serialized on the receiving end.
Is USB 3.0 still serial?
Most systems today do not have parallel and serial ports as they have been replaced with USB 2.0 or USB 3.0. A very old system (5-10 years) may have both parallel and serial ports. These are general purpose ports designed to communicate with external devices in standardized ways.
Is UART and USB same?
There is no difference, they are actually the very same port. The USB port of the module can be connected to the USB port of a host computer, provided that the GlobalTop USB driver is installed.
What is the advantage of USB?
One of the main benefits of using USB cables is their ability to carry more information per second (12 mb/second) than parallel cables (115 kb/second). This means faster data transfer. Another advantage that goes with an USB cable is that its port is smaller than parallel cable port.
What is the weakness of USB?
Security Threats Some of the USB drives does contain a security weakness in the form of encryption. This type of weakness can pose security threats revealing all of your confidential data. For overcoming this most the flash manufacturers has come up with a updated software that all the users should check with.
What are the 4 benefits of USB?
Biggest Advantages of Flash Memory
- Increased Durability. Unlike traditional hard-disk drives, flash drives lack moving parts.
- Maximum Portability.
- Plenty of Storage Capacity.
- Fast Transfer Speeds.
- Compatibility with Many Devices.
- Use Flash Drives as Promotional Materials.
