Question : What is protocol? Name any 5 protocols.

Answer : In computing, a protocol refers to a set of rules or procedures that define how data is transmitted and received over a network. Protocols ensure that devices and software applications can communicate with each other effectively, and they define the format and structure of the data being transmitted.

Here are five common protocols used in computer networking:

1. TCP/IP (Transmission Control Protocol/Internet Protocol): TCP/IP is the standard protocol used for transmitting data over the internet. It provides a reliable, connection-oriented service for sending and receiving data packets.
2. HTTP (Hypertext Transfer Protocol): HTTP is the protocol used for transmitting data between web servers and web browsers. It defines the format and structure of web pages and other resources, and enables web browsers to retrieve and display content from web servers.
3. FTP (File Transfer Protocol): FTP is a protocol used for transferring files between computers over a network. It provides a simple, reliable method for uploading and downloading files.
4. SMTP (Simple Mail Transfer Protocol): SMTP is the protocol used for transmitting email messages between email servers. It defines the format and structure of email messages and ensures that they are delivered to the correct recipient.
5. DNS (Domain Name System): DNS is a protocol used for translating domain names into IP addresses. It enables users to access websites and other resources on the internet by typing in a human-readable domain name, rather than a numerical IP address.

Question : What is the difference between Shareware and Freeware Software?

Answer : Freeware refers to software that is completely free to use and distribute. This means that users can download and use the software without paying anything, and they are not required to purchase a license or provide any personal information. Freeware is typically available for personal or non-commercial use, and it may be limited in terms of features or functionality.

Shareware, on the other hand, is software that is free to use for a limited trial period. After the trial period expires, users are required to pay for a license if they wish to continue using the software. Shareware is often fully functional during the trial period, so users can get a sense of what the software can do before they decide whether to purchase it. Shareware is typically available for both personal and commercial use.

Question : What is the difference between Open Source Software and Proprietary Software?

Answer : Open source software refers to software that is freely available and can be modified and distributed by anyone. The source code of open source software is available for users to view and modify, which means that users have the ability to customize the software to meet their specific needs. Open source software is typically licensed under an open source license, which allows users to use, modify, and distribute the software without restrictions.

Proprietary software, on the other hand, is software that is owned and licensed by a specific company or organization. The source code of proprietary software is not freely available, which means that users cannot view or modify it. Proprietary software is typically licensed under a proprietary license, which restricts how users can use the software and may require users to pay a fee to use it.

Answer : Open Source Software : Mozilla Firefox, VLC Media Player, Linux

Proprietary Software : Microsoft Windows, Adobe Photoshop, Microsoft Office.

Question : What is the difference between Hackers and Crackers?

Answer : A hacker is someone who is skilled in computer programming and has an interest in exploring and understanding computer systems. Hackers are often motivated by a desire to learn and innovate, and they may use their skills to improve computer security, develop new software, or test the limits of computer systems. Hackers are not necessarily malicious or criminal in their activities, and some may even work in the computer security industry.

A cracker, on the other hand, is someone who uses their programming skills to break into computer systems or steal information. Crackers are motivated by malicious intent and may engage in activities like stealing passwords, injecting viruses or malware, or causing other types of damage to computer systems. Crackers are often associated with criminal activities and may be prosecuted under computer crime laws.
