The document discusses primary and secondary computer memory. Primary memory (RAM) temporarily stores active data and instructions, but loses data when powered off. Secondary memory (hard disks, SSDs) can permanently store data and is larger than primary memory but slower to access. RAM sizes are typically gigabytes while hard disks are terabytes. The document also describes ROM as read-only primary memory used to store basic input/output programs.
COMPUTER SYSTEM
A computer system consists of four major parts: hardware, software, users, and data. Hardware refers to the physical components of the computer like processors and monitors. Software includes the programmed instructions that tell the computer what tasks to perform. Users are the people who operate computers. Data comprises the individual facts and pieces of information that are processed by the computer system.
Computer Software.pptx
Software consists of a series of instructions that tell the computer what tasks to perform. There are two main categories of software: system software and application software. System software includes operating systems, which coordinate activities between hardware and software, and utility programs, which help manage the computer. Application software is designed to be useful to users, such as word processors or games. A programmer develops software by writing the instructions to process data into information.
Application software
Application software consists of programs designed to assist users with tasks like business activities, graphics projects, personal tasks, and communication. There are many types of application software including packaged software sold in stores, custom software for specific needs, web applications, open source software, and freeware or shareware distributed for free or for a trial period. Common business application software includes word processing, spreadsheet, database, presentation, and accounting programs to help users and businesses be more efficient.
Information Technology And Its Importance
Information technology (IT) has become integral to all aspects of modern life. It encompasses fields like programming, databases, networking, and web design, and can be divided into hardware and software. Hardware includes devices like computers, routers, and printers, while software includes operating systems, programs, and websites. The internet, one of IT's greatest achievements, serves as a global platform for communication, data transfer, and online transactions. IT is used in many domains like education, healthcare, business, and finance to automate processes, share information, and achieve organizational goals. As technology continues to evolve rapidly, adapting to new advances will be important for individuals and organizations.

Uses
- 1. Uses Personal computers are normally operated by one user at a time to perform such general purpose tasks as word processing, internet browsing, e-mail and other digital messaging, multimedia playback, video game play, computer programming, etc. Other more specific functions usually performed with the help of a PC include working, teleworking, learning, researching, printing, online banking, online shopping and dealing online with public sector institutions and services. The user of a modern personal computer may have significant knowledge of the operating environment and application programs, but is not necessarily interested in programming nor even able to write programs for the computer. Therefore, most software written primarily for personal computers tends to be designed with simplicity of use, or "user-friendliness" in mind. However, the software industry continuously provide a wide range of new products foruse in personal computers, targeted at both the expert and the non-expert user.
