An addressing mode in which the location of the data is contained within the mnemonic, is known as  Correct Answer Implied addressing mode 

An addressing mode in which the location of the data is contained within the mnemonic is known as implied/implicit addressing mode. It is also known as "Implicit" or "Inherent" addressing mode. As in this mode, the operand is specified implicitly in the definition of instruction.

CLC clears the carry flag.

RTS returns the CPU from a subroutine to the part of the program which initially called the subroutine.

SED sets the decimal flag.

LDA retrieves a copy from the specified RAM or I/O address and stores it in the accumulator.

It supports different addressing modes such as immediate, indirect, indexed, etc.

Example: LDA 2000H

In 8085 microprocessor, this instruction consists of a 16-bit memory address ( 2000H)  as part of the instruction

Addressing modes of 8085:

Immediate addressing mode:

In immediate addressing mode, the source operand is always data. If the data is 8-bit, then the instruction will be of 2 bytes, if the data is of 16-bit then the instruction will be of 3 bytes.

Register addressing mode:

In register addressing mode, the data to be operated is available inside the register(s) and register(s) is(are) operands. Therefore, the operation is performed within various registers of the microprocessor.

Direct addressing mode:

Indirect addressing mode, the data to be operated is available inside a memory location and that memory location is directly specified as an operand. The operand is directly available in the instruction itself.

Register indirect addressing mode:

In register indirect addressing mode, the data to be operated is available inside a memory location and that memory location is indirectly specified by a register pair.

Implied/Implicit addressing mode:

In implied/implicit addressing mode the operand is hidden and the data to be operated is available in the instruction itself.

Which of the following statements are true?
Statement I Big data refers to no precise quantity, but generally refers to data in the range of Petabytes and Exabyte, i.e. billions to trillions of records, all from various sources. Big data is generated much faster. than traditional data in much larger quantities.
Statement II Big data interests industries because they are able to learn more patterns and curious variances than smaller data sets, with the capability to provide valuable insights into consumer behaviour, weather systems, financial market activity, or other phenomena.
Statement III Various departments and product lines use various applications within most organisations and store data in separate datasets. These separate databases may contain similar data, but data from one data base to another is not always consistent. This is called data silo.
Consider the statements given below- A: Relationship between Mean, Median and Mode is : Mode = 3 Median – 2 Mean B: It is also possible that there can be more than one mode or no mode for a data set. C: In a data set, half of the data points are smaller than the median and half of the data points are larger. Which of the above statement(s) is/are TRUE?

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create anapplication. The application uses the ADO.NET Entity Framework to model entities. Theapplication allows users to make changes to entities while disconnected from the central data store. You need to ensure that when the user connects to the central data store and retrieves new data, the application meets the following requirements:
  • Changes made to the local data store in disconnected mode are preserved.
  • Entities that have already been loaded into the local data store, but have not been modified by the user, are updated with the latest data.
