Distinguish between serial and parallel processing software#
We see how hardware and software work together.Big picture of communication over network is understandable through this OSI model.In the table below, we have specified the protocols used and the data unit exchanged by each layer of the OSI Model. They are:īelow we have the complete representation of the OSI model, showcasing all the layers and how they communicate with each other. It defines seven layers or levels in a complete communication system. The ISO-OSI model is a seven layer architecture. This is called a model for Open System Interconnection (OSI) and is commonly known as OSI model. ISO stands for International organization of Standardization.
Distinguish between serial and parallel processing iso#
So to ensure, national and worldwide data communication, systems must be developed which are compatible to communicate with each other ISO has developed a standard. There are n numbers of users who use computer network and are located over the world. Difference between OSI and TCP/IP Model.TCP/IP REFERENCE MODELCOMPUTER NETWORKS.Connection Oriented and Connectionless Services.Printers, Hard Drives, CD drives use parallel ports.
Distinguish between serial and parallel processing serial#
Modems, security cameras, device controllers use serial ports. of wires that are connected to parallel port are quiet high as compared to serial port.Ī serial port is able to transmit a single stream of data at a time.Ī parallel port is able to transmit multiple data streams at a time.Ī serial port sends data bit by bit after sending a bit at a time.Ī parallel port sends data by sending multiple bits in parallel fashion. Wire connections to serial port are quiet less as compared to parallel port. Top-down model has high ratio of redundancy as the size of project increases. Transmission speed of a parallel port is quiet high as compared to a serial port.īottom-Up model is better suited as it ensures minimum data redundancy and focus is on re-usability. Transmission speed of a serial port is slow as compared to a parallel port. Parallel Port is used for parallel data transmission. Serial Port is used for serial data transmission. A parallel port uses D-25 connector, a 25 pin D-Shaped connector which connects to the transmission wires.įollowing are the important differences between Serial Ports and Parallel Ports. To avoid such issues, the wires are kept small in length. All lines speed should be same to avoid error and cross-talk issues. Parallel ports are used in connecting printers, hard-drives, CD-drives etc. Parallel ports provide an interface to connect multiple lines to prepare a parallel communication to send large data at a time. A serial port provides a serial communication using one line and thus have no dependency on other wire's speed and its length can be extended as per the need. A Serial port uses DB-9 connector, a 9 pin D-Shaped Connector which connects to the transmission line. Serial ports are typically used in modem, mouse, security cameras etc. Serial Ports provide an interface to connect serial lines to prepare a serial communication.
