How to use search engines effectively?

Search engines have become an essential part of today’s digital world, they help us find out any information quickly and easily. Although plenty of information available on internet, sometimes we cannot find the information we are searching. This is why we must know how to use search engines to search what we are looking for. In this lesson we will learn the basics of search engines and effective ways to use it.

1. Keywords: Key words are the basics of search engines; these are the terms or phrases that we use to search information on search engines. As we enter any key word on search engine it will give a list of results of web pages which contain that key word. Accurate and usefulness of the results depends how relevant and specific keywords we enter.

2. Boolean Operators: Boolean operators are special characters that can be used in combination with key words that will make your search result more precise. To combine multiple keywords we can use AND, OR and to exclude certain information, we can use NOT.

3. Quotation Marks: Quotation marks are used to refine your search results. We can enclose a phrase in quotation marks and search the exact phrase instead just combination of individual keywords.

4. Advanced Search: Almost all search engines have this tool which helps us to find information precisely based upon criteria specified. For instance, by using Advanced search tool to search a website that have been updated within a certain time frame or to search pages that contains particular types of files. E.g. PDF,DOC, etc.

5. Search Results: When we search anything on search engines the results that we get are based upon ranking given by relevance. Generally, the most relevant result will appear on the top of the list, while less relevant results will appear down the page. A complex algorithm decides the ranking of results which considers various factors like the relevance of the content, the quality and quantity of links to drive traffic to the page, and the popularity of the website.

6. Cached Pages: Many search engines allow us to view cached pages, which are screen shots that had been saved by the search engines at some particular time. Cached pages help if a web page has been removed or changed since it was indexed by the search engine.

7. Sponsored Results: Besides, the standard search results, sponsored results could also be seen at the top or bottom of the page, these are paid advertisements that companies or organizations use to market their products or services.

8. Privacy: When the search engines search any information they also retain your details of your location and the devices that you are using. By doing this, the search engines can improve the quality and relevancy of your query. Sometimes the hackers take advantage of this system. You can secure your information by using privacy focused search engine, deleting your search history and minimizing the input of your personal information.

In conclusion, search engines are an important tool in this digital world, by knowing its algorithm we can use them effectively, and search relevant information very easily.

#2 Basics of Computers: An Introduction

Basics of Computers: An Introduction

In today's digital age, having a fundamental grasp of how computers operate is crucial, since they have become a vital part of our everyday lives. This lesson will give a general overview of a computer's parts and how they interact to carry out tasks.

1. Hardware: A computer's physical parts are referred to as hardware as a whole. These include the motherboard, graphics card, hard disc, memory (RAM), input/output (I/O) devices such the keyboard, mouse, and monitor, as well as the central processor unit (CPU).

2. Software: The programs and apps that operate on a computer are referred to as software. System software, which contains the operating system and other low-level applications, and application software, which comprises programs that carry out specialized functions like word processing, spreadsheet management, and web surfing, are the two categories into which software may be divided.

3. Central Processing Unit (CPU): Also referred to as the "brain" of the computer, the CPU is in charge of carrying out computations and executing commands. The central processing unit (CPU) is a tiny device with millions of transistors that process data.

4. Operating System: The software that manages a computer's hardware and applications is known as the operating system (OS). The OS is in charge of controlling resources like memory and processing power as well as giving users a way to communicate with the machine. Windows, Linux, Mac OS, and other common operating systems are examples.

5. Random Access Memory (RAM): The computer uses RAM, also known as temporary storage, to keep data and instructions while the CPU is processing them. RAM is volatile, which means that when the computer is shut off, the data stored inside is lost.

6. Hard Drive: Used to store data and program permanently, the hard drive is a non-volatile storage device. The hard drive, which is bigger and slower than RAM, stores data on magnetic discs.

7. Motherboard: The motherboard is a computer's primary circuit board that houses the CPU, RAM, and other essential parts. The motherboard is in charge of connecting all of the parts and enabling communication with each other.

8. Graphics Card: The graphics card, which is independent of the CPU and is responsible for producing pictures and movies, The graphics card has its own GPU (graphics processing unit) and VRAM (video RAM) memory (video random access memory).

9. Input/output Devices: Information is entered into computers using input devices like the keyboard and mouse. Information is shown through output devices, such the monitor. 

10. Networking: By connecting computers to one another to create a network, computers may share resources like printers and data. Users may interact and access information over the internet, a worldwide network of computers, from any location in the world.

11. Security: Viruses, malware, and cyber attacks are just a few of the security risks that computers and networks are susceptible to. It is important to protect computer systems and networks with security measures such as firewalls, anti-virus software, and strong passwords.
