Scheduling

9 / 25

During the program execution, temporary/intermediate values are stored in:

None of these

10 / 25

The advantage of I/O mapped devices to memory mapped is:

The devices connected using I/O mapping have a bigger buffer space

The former offers faster transfer of data

The devices have to deal with fewer address lines d) No advantage as such

11 / 25

The method of synchronising the processor with the I/O device in which the device sends a signal when it is ready is:

DMA

Interrupts

Exceptions

Signal handling

12 / 25

The objects can be inherited by:

A single object only

Multiple objects

Either (a) or (a)

Both (a) and (b)

13 / 25

An interrupt that can be temporarily ignored is:

Non-maskable interrupt

Vectored interrupt

High priority interrupt

Maskable interrupt

14 / 25

The system is notified of a read or write operation by:

sending a special signal along the BUS

Enabling the read or write bits of the devices

Raising an appropriate interrupt signal

Appending an extra bit of the address

15 / 25

When each item of data in a database is directly linked with every other item of data, the database is called:

None of these

Network

Relational

Hierarchical

16 / 25

When the LAN is arranged in such a way that each computer is connected directly to the HUB the configuration can be termed as .......................network:

Ring

Star

Bus

None of these

17 / 25

18 / 25

State Transition Diagram gives information of:

Control Flow

None of these

Data Flow

Entry Relationship

19 / 25

The process where in the processor constantly checks the status flags is called as:

Polling

Echoing

Inspection

Reviewing

20 / 25

The interrupt-request line is a part of the:

None

Control line

Data line

Address line

21 / 25

To overcome the lag in the operating speeds of the I/O device and the processor we use:

Interrupt signals

Buffer spaces

Exceptions

Status flags

22 / 25

A linear sequential software development model is also referred to as:

RAD Model

None of these

Spiral Model

Prototype Model

23 / 25

The .................. operation changes the coordinate values of objects being displayed:

Both (a) and (b)

Transformation

Windowing

None of these

24 / 25

In memory-mapped I/O:

The I/O devices and the memory share the same address space

The I/O devices have a seperate address space

A part of the memory is specifically set aside for the I/O operation

The memory and I/O devices have an associated address space

25 / 25

Main memory is called RAM because:

It is volatile, like a ram’s temper

The computer starts at address 0 and reads every byte until it reaches the correct address

It can Read all memory

The memory is accessible randomly

Your score is

The average score is 0%
