When a picture is shown that comes from the computer what type of device is this input or output or storage?

Short Answer:

A picture being displayed on the monitor would be output.

Long Answer:

Put simply: If the computer is giving you the information it is output. If you are giving the computer information it is input. If the information is being held by the computer it is storage.

If we're talking about the actual file the picture is stored in then it would be storage, if we're talking about the picture displayed on the monitor it is output.

If you're talking about Monitors, Speakers, Printers then those are outputs.

Keyboard, Mouse, Touchpad, Touchscreen, Scanner, Microphone are all inputs.

Hard disk, floppy disk, memory stick, memory card, optical disk (cd/dvd/blur-ray) are all storage.

Multifunction devices can be both so you have to talk about a specific part of it to decide if it is input or output. For instance these days printers usually have a scanner on them and are called multi-function devices.

Because the development of computers has been largely the work of scientists, it is natural that a large body of computer applications serves the scientist. To solve scientific problems researchers must deal with the language of science: mathematics. To understand more deeply complex natural phenomena, scientists must use complex mathematical relationships and volumes of data too impossible to manage without the aid of computers. Many scientific computer programs serve the entire population. The links included herein relate to computers and their uses.

Judging by the poor spelling on the Brontok webpage, "Anda Setuju?" probably means "And Setup?", so don't click OK on the pop-up box.

A computer has 32 bit instructions and 12 bit addresses. If there are 250 two address instructions how many one address instructions can be formulated?

There are 250 2-address instructions. There are only a total of 256 2-address instructions allowed if we have 32-bit instructions (two addresses take up 24 bits, leaving only 8 bits for the opcode). Looking at the 8 bit opcode, assume bit patterns 00000000 (0) through 11111001 (249) are used for the 250 two-address instructions. Then there are 6 bit patterns left for one address instructions. However, each one of these can use the remaining 12 bits gained from having only one operand, so we have 6 * 212. 00000000 11111001 11111010 11111010 ... 11111111 11111111 ______________________________________________________________________________ xxxxxxxxxxxx xxxxxxxxxxxx 000000000000 111111111111 000000000000 xxxxxxxxxxxx 111111111111 xxxxxxxxxxxx xxxxxxxxxxxx xxxxxxxxxxxx xxxxxxxxxxxx xxxxxxxxxxxx 250 2-address instructions 212 212 6 * 212 1-address instructions
