What is the use of MDR?

Multidrug-resistant TB (MDR TB) is caused by an organism that is resistant to at least isoniazid and rifampin, the two most potent TB drugs. These drugs are used to treat all persons with TB disease.

What are the four main types of registers?

Different Types of Registers

MAR Register. The full form of MAR is the memory address register.
MDR. The full form of MDR register is a memory data register.
MBR. The full form of MBR is the memory buffer register.
PC. The full form of PC is the program counter register.
Accumulator.
Index Register.
Instruction Register.

What is data register and its use?

memory data register (MDR) A register used for holding information (either program words or data words) that is in the process of being transferred from the memory to the central processor, or vice versa.

What is the uses of data register?

Memory Data Registers are registers of computers that contain data that will be stored in the computer’s storage or that will be retrieved from the computer’s storage after a fetch. As a buffer, it holds anything that is copied from the memory that is ready for use by the processor.

What is the use of data in register?

A register is basically a storage space for units of memory that are used to transfer data for immediate use by the CPU (Central Processing Unit) for data processing. Also known as memory registers, they can actually form part of the computer processor as a processor register.

What is MDR full form?

Multiple Drug Resistant is the full form of MDR.

What is MDR and XDR-TB?

Multidrug resistance (MDR): This is when both isoniazid and rifampicin fail to work against TB infection. Extensive drug resistance (XDR): Extensively drug-resistant TB (XDR-TB) is a form of TB that is resistant to at least four of the core anti-TB drugs.

Which are the four categories of register?

9 . Which are the four categories of registers:

General‐ purpose register.
Pointer or index registers.
Segment registers.
Other register.
All of these.

Where are the data direction registers located in a microprocessor?

The data direction registers and the input/output port data registers are usually located near the edge of the processor’s package if included in the microprocessor and may be connected directly to the external circuits. Consequently, these are highly likely to have noise on their lines.

What is the difference between a serial port and a dedicated register?

Dedicated registers are used to organise the data stream and control the timing of the data transfer. The serial port is based on a shift register that converts between parallel data on the internal data bus and serial data on the peripheral line. The general principles of parallel and serial data transfer are shown in Figure 1.3.

What is the function of memory data register?

What are the different registers associated with each port?

Each Port is associated with 3 registers for direction configuration (Input/Output), read and write operation. note: Here ‘x’ could be A,B,C,D so on depending on the number of ports supported by the controller. Before reading or writing the data from the ports, their direction needs to be set.
