About Computers
 
A computer is a programmable electronic device that accepts raw data as input and 
processes it with a set of instructions (a program) to produce the result as output. It 
renders output just after performing mathematical and logical operations and can 
save the output for future use. It can process numerical as well as non-numerical 
calculations. The term "computer" is derived from the Latin word "computare" 
which means to calculate. 
A computer is designed to execute applications and provides a variety of solutions 
through integrated hardware and software components. It works with the help of 
programs and represents the decimal numbers through a string of binary digits. It 
also has a memory that stores the data, programs, and result of processing. The 
components of a computer such as machinery that includes wires, transistors, 
circuits, hard disk are called hardware. Whereas, the programs and data are called 
software. 
It is believed that the Analytical Engine was the first computer which was invented 
by Charles Babbage in 1837. It used punch cards as read-only memory. Charles 
Babbage is also known as the father of the computer. 
1. Micro Computer: 
It is a single-user computer which has less speed and storage capacity than the 
other types. It uses a microprocessor as a CPU. The first microcomputer was built 
with 8-bit microprocessor chips. The common examples of microcomputers 
include laptops, desktop computers, personal digital assistant (PDA), tablets, and 
smartphones. Microcomputers are generally designed and developed for general 
usage like browsing, searching for information, internet, MS Office, social media, 
etc. 
2. Mini Computer: 
Mini-computers are also known as "Midrange Computers." They are not designed 
for a single. They are multi-user computers designed to support multiple users 
simultaneously. So, they are generally used by small businesses and firms. 
Individual departments of a company use these computers for specific purposes. 
For example, the admission department of a University can use a Mini-computer 
for monitoring the admission process. 


Mass Media 
Think about this for a second: whenever you want to hear your favorite song
watch your favorite show, or see the latest current events, where do you go? You 
more than likely turn on your television, radio, or computer. The source that the 
majority of the general public uses to get their news and information from is 
considered mass media. 
Mass media
means technology that is intended to reach a mass audience. It is the 
primary means of communication used to reach the vast majority of the general 
public. The most common platforms for mass media are newspapers, magazines
radio, television, and the Internet. The general public typically relies on the mass 
media to provide information regarding political issues, social issues, 
entertainment, and news in pop culture.
