Computer fundamental MCQ Questions and answers- Technical Aptitude

The win.ini file is a Windows system file used with Microsoft Windows 3.x and 9x initialization that loads from the C:Windows directory and loads settings each time Windows boots. For example, the communication drivers, wallpaper, screen saver, languages and fonts are loaded each time the win.ini initializes. If this file becomes corrupt or bad, Windows will either not load, or have several errors as it loads.

SMTP (Simple Mail Transfer Protocol) is a TCP/IP protocol used in sending and receiving e-mail.

Sent by computer engineer Ray Tomlinson in 1971, the email was simply a test message to himself. The email was sent from one computer to another computer sitting right beside it in Cambridge, Massachusetts, but it traveled via ARPANET, a network of computers that was the precursor to the Internet.

An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs.

After being initially loaded into the computer by a boot program, manages all the other programs in a computer. The other programs are called applications or application programs. The application programs make use of the operating system by making requests for services through a defined application program interface (API).

An arithmetic logic unit (ALU) is a combinational digital electronic circuit that performs arithmetic and bitwise operations on integer binary numbers.

A RAM chip is a microchip used as RAM storage for computers and other devices. This is the actual chip that is soldered onto small circuit boards in order to create RAM cards or sticks, and it is rated for performance and capacity differently, depending on the model and manufacturer.

A supercomputer is a computer with a high level of performance compared to a general-purpose computer. Performance of a supercomputer is measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS).

The operating system (OS) manages all of the software and hardware on the computer. It performs basic tasks such as file, memory and process management, handling input and output, and controlling peripheral devices such as disk drives and printers and all of the above.

A programmable read-only memory (PROM) or field programmable read-only memory (FPROM) or one-time programmable non-volatile memory (OTP NVM) is a form of digital memory where the setting of each bit is locked by a fuse or antifuse. It is one type of ROM (read-only memory). The data in them is permanent and cannot be changed.

PROMs are used in digital electronic devices to store permanent data, usually low level programs such as firmware (microcode).

ROM is an acronym for Read-Only Memory. It refers to computer memory chips containing permanent or semi-permanent data. Unlike RAM, ROM is non-volatile; even after you turn off your computer, the contents of ROM will remain. Almost every computer comes with a small amount of ROM containing the boot firmware.
