Computer fundamental MCQ Questions and answers- Technical Aptitude

Large-scale integration (LSI) is the process of integrating or embedding thousands of transistors on a single silicon semiconductor microchip. LSI technology was conceived in the mid-1970s when computer processor microchips were under development.

Output, or processed information in a usable format, comes in many different forms: monitor or printer for visual work, a speaker for audio. Sometimes our output is short-term, such as printing a photo, and sometimes what we work on needs to be kept around for a while. That's where storage comes in.

Band printers are a variation of chain printers in which a thin steel band is used instead of a chain, with the characters embossed or etched onto the band. Connected in series, one after the other. Transmitted signals go to the first device, then to the second and so on.

1) A type of simulation method using random numbers to determine the evolution of a system is Monte carlo.
2) Monte Carlo simulation is a computerized mathematical technique that allows people to account for risk in quantitative analysis and decision making.

A database management system based on the concept of ownership is Network database system. A network database is a type of database model wherein multiple member records or files can be linked to multiple owner files and vice versa.

A printer that prints a page at a time. Laser, LED and solid ink printers are examples. The first page printers were huge, floor-standing devices, and although such "digital printing presses" today print much faster and even in color, the ubiquitous page printer is the desktop laser printer.

Million instructions per second (MIPS) is an older, obsolete measure of a computer's speed and power, MIPS measures roughly the number of machine instructions that a computer can execute in one second.

ROM (Read Only Memory) and RAM make up the primary memory. Although one is volatile and the other contains non volatile firmware, the similarity is in that they are both directly accessed by the CPU.

The database management system (DBMS) is the software that interacts with end users, applications, and the database itself to capture and analyze data.

A disk is divided into tracks, cylinders, and sectors. A track is that portion of a disk which passes under a single stationary head during a disk rotation, a ring 1 bit wide. A cylinder is comprised of the set of tracks described by all the heads (on separate platters) at a single seek position.
