1) Automatic: Given a job, computer can work on it
automatically without human interventions
2) Speed: Computer can perform data processing jobs
very fast, usually measured in microseconds (10
-6
),
nanoseconds (10
-9
), and picoseconds (10
-12
)
3) Accuracy: Accuracy of a computer is consistently high
and the degree of its accuracy depends upon its design.
Computer errors caused due to incorrect input data or
unreliable programs are often referred to as Garbage-
In-Garbage-Out (GIGO)

## FAQs on Introduction to Computers - Computer Fundamentals

 1. What is computer fundamentals?
Ans. Computer fundamentals refer to the basic principles and components of a computer system. It includes understanding the hardware, software, operating systems, networks, and applications that make up a computer.
 2. What are the main components of a computer system?
Ans. The main components of a computer system are the central processing unit (CPU), memory, input devices (keyboard, mouse), output devices (monitor, printer), storage devices (hard drive, USB), and the motherboard that connects all these components.
 3. What is the role of an operating system in a computer?
Ans. An operating system (OS) is a software that manages computer hardware and software resources. It acts as an interface between the user and the computer, allowing the user to interact with applications and perform tasks. It also manages memory, files, and controls the execution of programs.
 4. How does a computer network work?
Ans. A computer network is a collection of interconnected devices that can share resources and communicate with each other. It works by using network protocols (rules) to transmit data between devices. The devices can be connected using wired connections (Ethernet cables) or wireless connections (Wi-Fi). Data is transmitted in the form of packets, which are small units of information.
 5. What are some common computer applications?
Ans. Common computer applications include word processors (Microsoft Word, Google Docs), spreadsheets (Microsoft Excel, Google Sheets), presentation software (Microsoft PowerPoint, Google Slides), web browsers (Google Chrome, Mozilla Firefox), and email clients (Microsoft Outlook, Gmail). These applications allow users to perform various tasks such as creating documents, analyzing data, making presentations, browsing the internet, and managing emails.
