SCHEME OF EVALUATION Socket and slots Socket is a place where we can fit electronic devices and Slot is an opening in the motherboard which will allow plugging in the circuit boards. Through this we can insert or connect the external devices in to the motherboard. There they are designated as Socket 7, Socket 8, Slot 1, Slot 2, socket 360, slot A, socket A, socket 432. (each of them should explain in brief) QUESTION_TYPE DESCRIPTIVE_QUESTION QUESTION_ID 74020 QUESTION_TEXT Describe the working of serial port functioning. Serial Port Functioning (3 marks) Serial port performs many important functions- Some of them are: Parallel data needs to be converted into a series of serial bits; appropriate framing bits needs to be added and the data line is to be provided with those bits at the proper rate. o It must also work in the reverse process is the serial data must be accepted at a known rate; framing bit must be removed and the serial data converted to bus form SCHEME OF EVALUATION The key component part of serial port is a single chip which is known as universal asynchronous receiver/transmitter (UART). It is the controller that takes bytes of data and transmits each data bit in a sequential fashion. At the destination end there is another UART controller which reassembles the individual bits into complete byte. UART is used in modems as well as for nonnetworked communication between computers, terminals and other devices. DTE vs DCE (3 marks) DTE stands for data terminal equipment and is considered to be a dumb terminal or a serial port of a computer DOE stands for data carrier communication and is normally a modem or any other piece of data Communication equipment There is an important distinction between DTE and DCE because data and handshaking signals are swapped at the DCE end. For example, the transmit pin which exists on the 3rd pin of a DTE cannot be directly connected to the same pin of the DCE. Rather, it must be routed through receive pin. DCE is responsible for such swaps so that the 3rd pin on the transmit pin connector gets connected to related pin on the transmit receive pin. Two DTEs cannot be connected with a straight-through cable. However null modem is used to swap the signals and connect the transmit lines between the two DTE. Serial Port Signals marks) (4 Serial post signals are very helpful in easily turning on and off by a switch. Signals can also be sued to monitor external devices without exchanging the serial data. Signals provide messages like loss of power, battery low alarm and status information with the help of power supply model. Serial port uses either 25-pin connector or 9-pin subminiature D-type connector to be used in the PC.. Serial cables are identical at both the ends. Like parallel port, serial connections also have three types of signals namely, data lines, control lines, and ground lines. Data signals are the conductors that information from the serial port to or from the modem or other peripheral. Control signals are bidirectional protocol used between sender and receiver, to acknowledge the sender that the data is received Ground signal is used to reduce the noise effects in the signal. The data signals and control are bipolar in nature. Bipolar signals are also called as bipolar transmission. It is a method of sending binary data over cable or wire. These signals are represented by 2 logic states high and low and denoted by logic 1 and logic 0. QUESTION_TYPE DESCRIPTIVE_QUESTION QUESTION_ID 119569 QUESTION_TEXT Define BIOS. Explain various BIOS features. BIOS is an electronic program that instructs the computer to start operation. BIOS occupy 128KB of upper memory space in the motherboard.
