Explanation
A botnet is a network of computers that have been infected with malicious software, or bots, which are controlled by a central command and control server. These infected computers, also known as zombies, can be linked together to form a botnet. The purpose of a botnet is often to carry out coordinated attacks, such as distributed denial of service (DDoS) attacks, spamming, or stealing sensitive information. By leveraging the power of multiple computers, botnets can be highly effective in carrying out malicious activities while remaining difficult to trace back to the perpetrators.

Explanation
Files are usually "zipped" to consolidate them into one large file, which is compressed to decrease its size and reduce the download time.

Explanation
The term "blended" is used by security experts to describe malware that combines multiple types of malicious programs. This means that the malware incorporates different techniques and functionalities to carry out its malicious activities. By combining different types of malware, attackers can increase the complexity and effectiveness of their attacks, making it more difficult for security measures to detect and mitigate them. Blended malware can include elements such as viruses, worms, Trojans, spyware, and more, making it a potent and versatile threat.

Explanation
The given correct answer is "video editing". This is because the question describes a software that provides tools for transferring video footage from a camcorder to a computer, clipping out unwanted footage, assembling video segments in any sequence, adding special video effects, and adding a sound track. All these activities are part of the process of video editing, which involves manipulating and enhancing video footage to create a final edited video.

Explanation
The term "software" refers to any type of application or program that can be used on a computer or electronic device. In this context, the given answer states that software can be defined as any type of application software that has the potential to help people do their work more efficiently. This definition emphasizes the purpose of software, which is to enhance productivity and improve efficiency in various tasks and activities.

Explanation
The given answer "extension" correctly explains that a file extension is a three-letter suffix that is added to the file name to indicate the type or format of information contained in the file. File extensions are used by operating systems to associate files with specific programs or applications that can open and process them. It helps users easily identify the file type and choose the appropriate software to open and work with the file.

Explanation
A software suite refers to a collection of software applications that are sold together as a single package. It typically includes multiple related software programs that are designed to work together and complement each other. This term is commonly used in the software industry to describe a bundle or package of software applications that are marketed and sold as a unified product.

Explanation
The given answer "document" is correct because the question is asking for the type of software that assists with composing, editing, designing, printing, and electronically publishing documents.

Therefore, "document" is the appropriate answer.

Explanation
From a legal perspective, there are two categories of software: public domain and proprietary. Public domain software refers to software that is not protected by copyright and can be freely used, modified, and distributed by anyone. On the other hand, proprietary software is protected by copyright and its use, modification, and distribution are restricted by the software owner. This means that proprietary software is owned by a specific individual or organization, and users must obtain a license or permission to use it.

Explanation
A header is text that is specified to automatically appear in the top margin of every page. It is a common feature in word processing software that allows users to add consistent information, such as page numbers, document title, or author name, to all pages of a document.
