History of computer what is computer
The history of computer is a timeline which shows the development of computers from their early days until today. It also looks at how they have changed over time, and what role they play in our lives today.
The first known use of a computer was in 1937, when Italian inventor Luigi nToledo Battista built an analog calculator that could add two numbers together. This was followed by several other developments during World War II — most notably with Alan Turings machine called "eckert-wcuells" The machine broke down problems into smaller pieces before solving them altogether (for example, arithmetic).
How many types of Computers
There are many types of computers. They range from small handheld devices to large servers, which can hold thousands of terabytes of data. The size and power of the computer depends on its purpose; some are designed for gaming or professional use, while others are simply meant for everyday tasks like web surfing or word processing.
Small-form factor computers include laptops and tablets, which were originally created as mobile devices but have since become popular among home users as well. Laptops feature small screens that can be carried around easily (although most models require an external keyboard and mouse), while tablets generally have larger displays that make them better suited for gaming purposes than work needs such as writing reports or creating presentations at school or work meetings
Computers come in all shapes and sizes, but there are only two basic types of computers: desktop and laptop.
The desktop computer is the traditional PC or Mac that sits on a desk or table at home or work. The laptop is a portable computer that can be taken anywhere with you. While many people still use desktop PCs as their primary computing device, laptops have become increasingly popular for both work and play because they're more portable and easier to carry around with you wherever you go.
How to Use Computer
How to use a computer is not a difficult task. If you are new to computers, it may take some time for you to get used to them but with practice and patience, you will master how to use computer in no time at all. The following steps will help you learn how to use computer:
1) Get an overview of the device
Before using any device or appliance for the first time, make sure that you know what each button does and where it goes when pressed down (e.g., power switch). This way, if anything goes wrong later on, the problem can be traced back immediately without having to check through manuals or online guides on how-to’s about your particular device (e.g., mobile phone).
2) Start small and simple
When learning how to use a computer for the first time , try taking it slow by starting off with something simple like surfing social media platforms such as Facebook , Twitter or Instagram . Once comfortable with these sites , move on towards more sophisticated tasks like webdesigning & coding which require knowledge of various programming languages like JavaScript
It is a fact that most people these days use the computer for their work. This is especially true for those who have a job in which they have to do some sort of research or analysis on the computer, or even just send out email messages and make phone calls.
If you are one of those people who use your computer frequently, then this article will give you tips on how to best use it so that it doesn't get too much out of shape after several months' worth of use.
The first thing that we will discuss here is memory capacity . People often think that more RAM means better performance from your computer's hard disk drive , but this isn't always true . In fact , if all else equal , having less RAM than needed can actually improve performance because there will be less data being moved around inside the machine . So when buying a new desktop PC or laptop with high-end specs (such as an Intel Core 2 Duo processor with 4GB+ ram) make sure that there is enough room left over for OS updates etc ..
What is pc
The expression "PC" was instituted by David L. Ken ert.
The first personal computer was made in 1975 and it was called the Altair 8800. It had no CPU, memory or storage devices; its operations were purely based on logic circuitry and switches. The Altair 8800 kit price was $399 which included a motherboard with eight bits of RAM, two switches and a manual that explained how to build your own computer circuit board from scratch! There were no hard drives or CD-ROM drives available at this time period so all programs ran off of floppy disks (!). This was considered to be one of the earliest home computers ever created — but it wasn't very powerful compared to today's standards!
The personal computer (PC) is an electronic device that can be used for various purposes. It has become an essential part of our daily lives and hence it has been given the name "personal computer". A PC is a small, portable computer that can be carried easily. You can use it at home, work or school and even on the go. The main purpose of using a PC is to perform tasks such as word processing, web browsing, video streaming etc., which can also be done by using mobile devices such as smartphones or tablets but if you compare them with computers then there are many advantages that come along with PCs such
as:
They are easy to use - Computer hardware controls all functions from keyboard keys to mouse clicks so no special training required here! In fact most people don't even need instructions when using their first computer because they learn by instinct how each key works in combination with other keys on the keyboard
