The computer is a great invention that is used in every field including corporate offices and private homes. Computers have made our day to day tasks easier to do and made a great impact in our society that is still evolving and changing each day. Workers are able to do their jobs more efficiently and allow interconnectivity between computer users all around the world through the Internet.
What is computer? Does everyone know what computer is? What is its function? Computer is the most probably used technology in our generation which is 21st century. But does anyone know what are computer and its function in our society? According to Margaret Rouse (2005), she said that a computer is a device that accepts information (in the form of digitalized data) and manipulates it for some result based on a program or sequence of instructions on how the data is to be processed. Complex computers also include the means for storing data (including the program, which is also a form of data) for some necessary duration. A program may be invariable and built into the computer (and called logic circuitry as it is on microprocessors) or different programs may be provided to
Hard Disc Drive: a HDD is like a person's long term memory. it is used to store any type of data from files to applications. The data on a HDD is non-volatile, which means the data will stay on the disc even if the computer is switched off. A SSD is another way to store data, but it is faster than a HDD because there are no moving parts.
For example, a word document is saved to a folder within a folder within a hard drive. Other files such as programs are saved onto the hard drive. Modern day HDDs are cheap and effective as the cost is low and the memory capacity can be of mass size, however, they are slow which makes HDDs a worthy competitor for SSDs. SSDs are flash memory drives, capable is holding programs and loading them faster than HDDs, however, small in memory capacity and expensive. Furthermore, you can combine the two. You can use the Solid state drive to save and quickly load programmes such as adobe Photoshop and use the hard disk driveto store images, videos, music and documents. I would recommend this powerful combination to anyone searching for fast performance and large memory capacities.
Main memory unit:It is called as temporary store house of the computer which stores data and programs .It is typically called volatile memory.(when the computer is shut down,the contents of the memory are lost,it is also called primary memory.
A processor is also known as a CPU which stands for central processing unit, is how a computer/laptop functions and this is like the brain of the computer the better the processor is, the faster a computer works
What is a computer? There are thousands of different types of computers that are built for an extremely vast range of purposes, but overall, what do you class as a computer? Anything with a CPU?
The first ever computer was invented in the 1820s by Charlse Babbage. However the first electronic digital computer were developed between 1940 and 1945 in the United States and in the United Kingdom. They were gigantic, originally the size of a large room, and also need to be supply a large amount of power source which is equivalent as several hundred modern personal computers. The history of computer hardware covers the developments from simple devices to aid calculation, to mechanical calculators, punched card data processing and on to modern stored program computers. The tools or mechanical tool used to help in calculation are called calculators while the machine operator that help in calculations is called computer. At first the

In order to store something in the main memory, it must first be input through the keyboard or mouse or other input device. A keyboard is designed to enter text, numbers, or punctuation. It is the main input device on most PC’s. The mouse is a pointing device used to select, point, and click on a computer screen. The keyboard and mouse are used to send information to the CPU. This information is translated through other devices called output devices such as the monitor. This
