Computer fundamental MCQ Questions and answers- Technical Aptitude

An elementary data item is a complete item that cannot be broken into separate parts. You can use elementary data items as host variables.

A computer is fundamentally made up of interconnected electronic circuits that process, store, and control data.

These electronic circuits include components such as transistors, resistors, capacitors, and integrated circuits, which work together to perform computations.

Chips, registers, and switching devices are all parts of electronic circuits, but they do not alone define the complete structure of a computer.

Hence, a computer can correctly be described as a box full of electronic circuits, making Option C the correct answer.

The concentric circles on the floppy disks are known as tracks. These tracks are further divided into pie-shaped sections known as sectors.

A one-bit signal that indicates the start of data transmission by an asynchronous device is Start bit. In telecommunication and data transmission, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus.

1) Registers which are partially visible to users and used to hold conditional codes (bits set by the CPU hardware as the result of operations), are known as Flags.
2) A bit field is a data structure used in computer programming.
3) A software or hardware mark that signals a particular condition or status.

An electronic circuit with about 20 transistors fabricated on a silicon chip is known as SSI. Short for small-scale integration, SSI is a chip generation first introduced in 1964 with between 1 and 10 transistors and 1 and 12 logic gates. 2. When referring to an Internet web page SSI is short for server-side include and is a file that includes Apache executable server code.

ASCII code. The American Standard Code for Information Interchange (ASCII) uses a 7-bit binary code to represent text and other characters within computers, communications equipment, and other devices. Each letter or symbol is assigned a number from 0 to 127.

Extended Binary Coded Decimal Interchange Code (EBCDIC) is an eight-bit character encoding used mainly on IBM mainframe and IBM midrange computer operating systems.

Third generation of computers is covered by the period 1964 - 77. The computers of the third generation used Integrated Circuits (ICs) in place of transistors. The Third generation of computers includes the development of the integrated circuit realized by the American engineer Jack Kilby (Jack St. Clair Kilby).

It was in 1982 when a group of programmers, led by John Walker, developed the first version of AutoCAD, the software that Michael Riddle, another member of that team, had created before.
AutoCAD is a commercial computer-aided design (CAD) and drafting software application. Developed and marketed by Autodesk Inc., AutoCAD was first released in December 1982 as a desktop app running on microcomputers with internal graphics controllers.
