A computer is an electronic device that accepts input, processes data according to instructions, stores the results, and produces output. It performs calculations and logical operations at very high speed and accuracy.

The major characteristics of a computer are as follows. First, speed — computers can perform millions of calculations in a fraction of a second. Second, accuracy — results are highly accurate if correct data and instructions are provided. Third, storage capacity — computers can store large amounts of data for future use. Fourth, diligence — unlike humans, computers do not get tired and can work continuously for long periods. Quick Tip: Computer works on IPO cycle — Input, Process, Output.

Hardware refers to the physical components of a computer that can be seen and touched, such as keyboard, monitor, mouse, CPU, and printer. These devices perform input, processing, storage, and output functions.

Software, on the other hand, consists of programs and instructions that tell the hardware what to do. Software cannot be touched. Examples include operating systems like Windows, application programs like MS Word, and antivirus software.

The main difference is that hardware is the physical part of the computer system, whereas software is the logical part that controls the hardware. Quick Tip: Hardware needs software to function, and software needs hardware to run.

The Internet is a worldwide network of interconnected computers that allows users to share information, communicate, and access various online services.

The Internet has many uses. It enables communication through email, video calls, and social media. It provides access to information through websites and online databases. It is widely used for online education and research. It also supports e-commerce, allowing people to buy and sell goods and services online. Quick Tip: Internet connects millions of networks across the world.

RAM (Random Access Memory) is the main memory of a computer used to store data and programs currently in use. It is volatile, meaning the data is lost when power is switched off.

ROM (Read Only Memory) is a permanent memory that stores essential instructions needed to start the computer. It is non-volatile and retains data even when the power is off.

The main differences are that RAM is temporary and volatile, while ROM is permanent and non-volatile. RAM allows both reading and writing of data, whereas ROM generally allows only reading. Quick Tip: RAM = Temporary memory, ROM = Permanent memory.

MS Excel is a spreadsheet software developed by Microsoft used for organizing, calculating, and analyzing data in tabular form. It allows users to perform mathematical operations, create charts, and manage large datasets efficiently.

Some important features of MS Excel include formulas and functions for automatic calculations, the ability to create charts and graphs for data visualization, sorting and filtering tools to organize data, and worksheets arranged in rows and columns for easy data entry. Quick Tip: Excel is widely used for accounting, data analysis, and reporting.
