Computer fundamental MCQ Questions and answers- Technical Aptitude

All inputs must be in ON position to have an output is known as AND gate. An AND gate is a logic gate having two or more inputs and a single output. An AND gate operates on logical multiplication rules. In this gate, if either of the inputs is low (0), then the output is also low. If all of the inputs are high (1), then the output will also be high.

The intersection of a column and row in a spreadsheet is called a bon of Cell. A cell is an area on a spreadsheet where data can be entered. Each cell acts as an individual entity in the spreadsheet. Cells are boxes formed by the intersection of vertical and horizontal lines that divide the spreadsheet into columns and rows.

A magnetic drum is a magnetic storage device used in many early computers as the main working memory, similar to how modern computers use random access memory (RAM) cards. In some cases, magnetic drum memory was also used for secondary storage.

The number of bits that are typically stored on each track of a magnetic disk is usually the same. There is two types of storage devices used with computers: a primary storage device, such as RAM, and a secondary storage device, such as a hard drive. Secondary storage can be removable, internal or external.

The silicon chips used for data processing are called Micro processor. A silicon chip is an integrated circuit made primarily of silicon. Silicon is one of the most common substances used to develop computer chips.

The code that should be adequate for present and anticipated data processing both for machine and human use is Operability. Operability is the ability to keep a piece of equipment, a system or a whole industrial installation in a safe and reliable functioning condition, according to pre-defined operational requirements.

Number of bit patterns provided by a 7 bit code 2⁷ = 128. It is based on Binary Number System (0 or 1).

The basic unit within a computer store capable of holding a single unit of data is Store location. It's commonly believed good location is the key element to attracting customers. A well-located store also makes supply and distribution easier. Location can influence a retailer's ability to market itself, and to deal with the competition it faces from other businesses.

A software bug is an error, flaw, failure or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways.

System software is computer software designed to provide a platform to other software. Examples of system software include operating systems like macOS and Windows, computational science software, game engines, industrial automation, and software as a service applications.
