5. Memory
Memory, also known as RAM (random access memory), is a temporary storage space inside the computer. It stores data that the CPU needs to access quickly for immediate use. The more memory a computer has, the more data it can store temporarily, resulting in faster and more efficient performance.
6. Storage Devices
Storage devices are hardware components used to store and retrieve data. They can be internal or external to a computer system. Examples of storage devices include hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives, and optical discs such as CDs and DVDs.
7. Input Devices
Input devices are used to enter data and commands into a computer system. Examples of input devices include keyboards, mice, touchscreens, scanners, and microphones. Input devices allow users to interact with the computer and provide instructions or information.
8. Output Devices
Output devices are used to display or present data processed by the computer. Examples of output devices include monitors, printers, speakers, and projectors. They allow users to view or hear the results of their inputs or commands.
9. Network
A network is a collection of interconnected computers and devices that can communicate with each other. Networks can be local, such as a home or office network, or global, such as the internet. Networks enable data sharing, communication, and collaboration between multiple users and devices.
10. Internet
The internet is a global network of interconnected computers and networks. It allows users to access and share information, communicate with others, and use various online services. The internet has revolutionized the way we connect and interact with the world, providing a vast array of resources and opportunities.
11. Website
A website is a collection of web pages accessible through the internet. It is hosted on a web server and can contain various types of content, such as text, images, videos, and interactive elements. Websites are used for various purposes, including sharing information, conducting business, and providing online services.
12. Browser
A browser is a software application used to access and view websites on the internet. It interprets the code of web pages and displays their content in a user-friendly format. Popular web browsers include Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari.
13. URL
A URL (Uniform Resource Locator) is the address used to locate a specific resource on the internet. It consists of various components, including the protocol (e.g., http:// or https://), domain name (e.g., example.com), and path to the resource. URLs are used to navigate between web pages and access specific content.
14. HTML
HTML (Hypertext Markup Language) is the standard markup language used to create web pages. It defines the structure and content of a web page using various tags and attributes. HTML allows for the inclusion of text, images, links, and other multimedia elements.
15. CSS
CSS (Cascading Style Sheets) is a stylesheet language used to describe the presentation and formatting of a document written in HTML. CSS allows web designers to control the layout, colors, fonts, and other visual aspects of a web page. It enhances the aesthetics and user experience of websites.
16. JavaScript
JavaScript is a high-level programming language used to add interactivity and dynamic behavior to web pages. It can manipulate web page elements, validate form inputs, and perform calculations. JavaScript is widely supported by web browsers and is essential for creating interactive web applications.
17. Firewall
A firewall is a security device or software that monitors and controls incoming and outgoing network traffic. It acts as a barrier between a trusted internal network and untrusted external networks, preventing unauthorized access and protecting against malicious activities. Firewalls play a crucial role in ensuring network security.
18. Virus
A virus is a type of malware (malicious software) that can replicate itself and spread to other computers or devices. Viruses can cause various types of damage, such as data loss, system instability, and unauthorized access. It is important to have antivirus software installed to protect against viruses.
19. Malware
Malware is a broad term that encompasses various types of malicious software, including viruses, worms, ransomware, spyware, and more. Malware is designed to disrupt computer operations, steal sensitive information, or gain unauthorized access to systems. It is important to have security measures in place to prevent malware infections.
20. Encryption
Encryption is the process of converting data into a form that cannot be easily understood by unauthorized individuals. It ensures the confidentiality and integrity of data by making it unreadable without the proper decryption key. Encryption is used to protect sensitive information, such as passwords, financial data, and personal details.
21. Cloud Computing
Cloud computing refers to the delivery of computing services over the internet. Instead of relying on local servers or personal computers, cloud computing allows users to access and use computing resources, such as storage, processing power, and software applications, from remote servers.
