Computer Fundamentals and System Concepts

Embedded computers are specialized computer chips integrated into other devices like cars, thermostats, appliances, and industrial equipment to perform specific control functions. Servers handle network requests, mainframes process large-scale data, and robotic computers control robots.

The steps and tasks needed to process data, such as responses to questions or clicking an icon, are called instructions.

A collection of programs that controls how your computer system runs and processes information is called operating system.

A set of instructions telling the computer what to do is called program.

Microsoft Office is a suite of productivity applications including Word, Excel, PowerPoint, and Outlook. It is commercial proprietary software, not public-domain or open-source. An application suite is a collection of related software programs sold together.

The Control Panel is a feature of the Windows operating system that allows the user to modify system settings and controls.

A captcha is a challenge-response test that determines whether a user is human or an automated bot.A typical captcha includes an image of distorted text and a form field for the user to enter the text. Captchas are commonly found at the end of website forms, and must be filled out in order for the form to be submitted. By requiring users to decipher and enter the captcha text, webmasters can prevent automated programs from sending spam or other unwanted data through online forms.

Telnet is a program that allows you log in to a Unix computer via a text-based interface.

The Control Panel is a feature of the Windows operating system that allows the user to modify system settings and controls.

These are large centralized computers and provide the bulk of business computing through time sharing.

This generation of computers were using integrated circuits as major electronic component.

Quarantine is the process in which anti-virus software prevents the computer program being infected by certain file which cannot be deleted.

This is the unit responsible for carrying out all arithmetic and logical operations inside a computer.

The most sophisticated terminals with built-in microprocessors and allow local editing, macros and other facilities.

CERN (European Organization for Nuclear Research) is the world's largest particle physics laboratory, located near Geneva. It developed the Worldwide LHC Computing Grid (WLCG) to process massive data from the Large Hadron Collider. CNN, BSN, and BSL are not scientific research organizations.
