1.
Backing storage is usually non-volatile, so it is generally used to store information
Correct Answer
B. For a long time
Explanation
The correct answer is "for a long time" because backing storage, such as hard drives or solid-state drives, is designed to retain data even when there is no power supply. This means that information stored in backing storage can be accessed and retrieved over an extended period, making it suitable for long-term storage purposes.
2.
USB memory and flash card are
Correct Answer
C. Solid state storage devices
Explanation
USB memory and flash cards are considered solid state storage devices because they do not have any moving parts and use solid state electronic memory to store data. They rely on flash memory technology, which is a type of non-volatile memory that retains data even when power is turned off. This makes them more durable, faster, and more reliable compared to magnetic or optical storage devices.
3.
The most suitable storage device to store high quality videos or films is
Correct Answer
B. DVD
Explanation
DVD is the most suitable storage device to store high quality videos or films because it has a larger storage capacity compared to floppy disks, CDs, and flash cards. DVDs can typically hold up to 4.7GB or more of data, which is sufficient for storing high quality videos. Floppy disks have very limited storage capacity and cannot accommodate large video files. CDs have a larger storage capacity than floppy disks but still fall short compared to DVDs. Flash cards, although they have larger storage capacities, are not as commonly used for storing videos or films as DVDs.
4.
Choose the magnetic storage device
Correct Answer
B. Hard disk
Explanation
A hard disk is the correct answer because it is a magnetic storage device. It uses magnetic fields to store and retrieve data, making it a suitable choice for this question. CD-ROM, Blu-ray, and pen drive are not magnetic storage devices, as they use different technologies such as optical or flash memory.
5.
SIM stands for
Correct Answer
D. Subscriber Identity Module
Explanation
SIM stands for Subscriber Identity Module. A Subscriber Identity Module is a small card that is inserted into a mobile device to identify and authenticate the user on a cellular network. It contains a unique identification number and stores the user's personal information, such as contacts and messages. The SIM card allows the user to make calls, send messages, and access mobile data services.
6.
DVD stands for
Correct Answer
B. Digital Versatile Disk
Explanation
The correct answer is "Digital Versatile Disk". DVD stands for Digital Versatile Disk, which is a type of optical storage medium used for storing and playing back high-quality video and audio content. It is a widely used format for movies, TV shows, and other forms of digital media due to its large storage capacity and compatibility with various devices.
7.
Data store capacity is measured in
Correct Answer
B. Bytes
Explanation
Data store capacity is typically measured in bytes. Bytes are the basic unit of measurement for digital information storage and are used to quantify the amount of data that can be stored in a device or system. Other units such as kilobytes, megabytes, and gigabytes are also commonly used to represent larger amounts of data.
8.
A thousand million bytes is called a
Correct Answer
B. Gigabyte
Explanation
A thousand million bytes is called a gigabyte. This unit of measurement is commonly used to represent large amounts of data storage. It is equivalent to 1 billion bytes or 1024 megabytes.
9.
One MegaByte is the same than
Correct Answer
A. 1000 KiloBytes
Explanation
One Megabyte is equal to 1000 Kilobytes. This is because the metric system uses a base of 10, so when converting from one unit to another, you multiply or divide by 10. In this case, since there are 1000 Kilobytes in a Megabyte, the correct answer is 1000 Kilobytes.
10.
The fastest device in access speed is
Correct Answer
C. Hard Disk
Explanation
The hard disk is the fastest device in terms of access speed compared to the other options listed. This is because hard disks use magnetic storage to store and retrieve data, allowing for faster read and write speeds. CD, USB memory, and floppy disks have slower access speeds due to their different storage mechanisms, such as optical or flash memory.
11.
Pharming is more efficient than phising because
Correct Answer
A. Attacks several users at the same time
Explanation
Pharming is more efficient than phishing because it attacks several users at the same time. By redirecting multiple users to a fake website, pharming can collect sensitive information from a larger number of victims simultaneously. This allows the attackers to maximize their efforts and increase their chances of success. In contrast, phishing typically relies on sending individualized fraudulent emails or messages, which may not reach as many users or have the same level of impact.

Correct Answer
D. All of the above
Explanation
Web 2.0 WebPages allow users to share information, collaborate on content, and create their own content. This means that users have the ability to not only consume information but also actively participate in the creation and sharing of content. Web 2.0 platforms enable a more interactive and user-driven experience, empowering individuals to contribute and engage with others in various ways. Therefore, the correct answer is "all of the above" as it encompasses all the mentioned capabilities of Web 2.0 WebPages.
13.
Phishing
Correct Answer
A. Uses e-mail as a tool to attack users
Explanation
Phishing is a type of cyber attack that uses email as a tool to deceive and manipulate users into revealing sensitive information such as passwords, credit card numbers, or personal data. The attacker typically poses as a trustworthy entity and tricks the user into clicking on a malicious link or providing confidential information. Deleting all email messages will not prevent phishing attacks as they can still be received in the future. Using a strong password can help protect against some types of attacks, but it does not specifically prevent phishing. Therefore, the correct answer is that phishing uses email as a tool to attack users.
14.
Spam is
Correct Answer
B. The use of e-mail to send unsolicited messages
Explanation
Spam refers to the use of email to send unsolicited messages. These messages are typically sent in bulk to a large number of recipients without their consent. Spam is often used for advertising purposes or to spread malware. It is considered a nuisance and can clog up email inboxes, causing inconvenience to users.
15.
A website that allows users to work together to create the content is known as
Correct Answer
C. Wiki
Explanation
A website that allows users to work together to create content is known as a wiki. This type of platform enables multiple users to collaborate and contribute to the creation and editing of articles or pages. Unlike social networks, where the focus is on connecting with others and sharing personal information, wikis are specifically designed for collaborative content creation. Media uploading sites, on the other hand, primarily focus on allowing users to upload and share media files such as photos or videos. Therefore, the correct answer is wiki.
