Varun Kapoor answered |
An arithmetic-logic unit (ALU) is the part of a computer processor (CPU) that carries out arithmetic and logic operations on the operands in computer instruction words. In some processors, the ALU is divided into two units, an arithmetic unit (AU) and a logic unit (LU). Some processors contain more than one AU - for example, one for fixed-point operations and another for floating-point operations. (In personal computers floating point operations are sometimes done by a floating point unit on a separate chip called a numeric coprocessor.)An arithmetic logic unit is also known as an integer unit (IU).

To move to the beginning of a line of text, you need to press the Home key. Here is a detailed explanation:
Explanation:
- When you are editing or typing a line of text, the Home key on your keyboard is used to navigate to the beginning of the line.
- Pressing the Home key will move the cursor to the leftmost position of the current line.
- This can be useful when you want to quickly jump to the start of a line without using the arrow keys or mouse.
HTML bullet points:
- Press the Home key: This key is located usually on the top row of your keyboard.
- Function: It allows you to move the cursor to the beginning of a line of text.
- Usefulness: It provides a quick way to navigate to the start of a line without using arrow keys or mouse.
- Alternative keys: Some keyboards may have alternative keys like Fn + Left Arrow or Ctrl + A to perform the same action.

Addressing in a RAM
Addressing is a process of assigning a unique identity to each memory location in a computer's Random Access Memory (RAM). The number of memory locations that can be addressed in a RAM depends on the number of bits used to specify the address.
16-bit Addressing
If a computer uses 16 bits to specify the address in a RAM, it means that each memory location can be uniquely identified by a 16-bit binary number. The total number of unique binary numbers that can be represented using 16 bits is 2^16.
Calculating the Number of Addresses
To calculate the number of addresses that can be specified using 16 bits, we need to convert 2^16 from binary to decimal.
2^16 in decimal is 65,536. Therefore, the number of addresses that can be specified using 16 bits is 65,536.
Answer
Hence, option B, 65,536 is the correct answer.

Anoushka Mehta answered |
Explanation:
A file extension is a suffix attached to the end of a file name to indicate the format or type of the file. It is separated from the main file name by a period (.) and does not contain any spaces.
Example:
Let's say we have a file named "document.txt". In this example, "document" is the main file name and "txt" is the file extension. The period separates the main file name and the file extension.
Importance of File Extensions:
File extensions are important because they help the operating system and software programs identify the file type and determine how to handle it. Different file extensions are associated with different file formats and can be opened by specific programs that are designed to work with those formats.
Common File Extensions:
Here are some common file extensions and their corresponding file formats:
- .txt: Text file
- .docx: Microsoft Word document
- .xlsx: Microsoft Excel spreadsheet
- .jpg: JPEG image
- .mp3: MP3 audio file
- .pdf: Portable Document Format
- .html: Hypertext Markup Language file
Conclusion:
In conclusion, a file extension is separated from the main file name by a period and does not contain any spaces. It helps identify the file type and determines which program should be used to open and work with the file.

Harsh Gupta answered |
**Answer:**
The correct answer is **A) IP (Internet Protocol)**.
**Explanation:**
**1. Internet Protocol (IP):**
IP stands for Internet Protocol. It is a network layer protocol that provides a common address space and routes the packets of data across the entire internet. It is responsible for delivering data packets from the source host to the destination host based on the IP addresses assigned to each host.
**2. Common Address Space:**
IP provides a common address space by assigning a unique IP address to each device connected to the internet. An IP address is a numerical label assigned to each device, and it serves as the device's identity on the internet. It consists of two parts - network address and host address. The network address identifies the network to which the device belongs, and the host address identifies the specific device within that network.
**3. Routing of Data Packets:**
IP also routes the packets of data across the entire internet. When a device wants to send data to another device on the internet, it divides the data into smaller chunks called packets. Each packet is then encapsulated with the necessary information, including the source and destination IP addresses.
The source device sends the packets to its default gateway, which is a device responsible for forwarding the packets to the appropriate destination. The default gateway examines the destination IP address of each packet and determines the next hop on the route towards the destination. It forwards the packets to the next hop, and this process continues until the packets reach the destination device.
**Conclusion:**
In summary, IP is the protocol that provides a common address space by assigning unique IP addresses to devices and routes the packets of data across the entire internet based on these IP addresses. It ensures that data packets are delivered to the correct destination by following the appropriate routing paths.

Pranav Mehta answered |
Explanation:
When a new device is attached to a computer, the computer does not automatically recognize it. In order to use the device, the computer needs to have the appropriate software installed. This software is called a driver.
A driver is a type of software that allows the computer to communicate with the device. It provides the necessary instructions for the computer to understand and use the device. Without a driver, the computer cannot use the device, and it will not function properly.
There are different types of drivers for different devices. For example, there are drivers for printers, scanners, cameras, and other peripherals. Each driver is specific to the device it is intended to work with.
Installing a driver is a simple process. Most devices come with a CD or DVD that contains the necessary software. The user simply needs to insert the CD into the computer and follow the instructions that appear on the screen. In some cases, the driver may be downloaded from the manufacturer's website.
In conclusion, a driver is necessary for a computer to use a new device. It is a type of software that allows the computer to communicate with the device and use it properly.

Sequential Access Method for File Organization
Sequential access method is a file organization technique in which data records in a file are arranged in a specific order according to a key field. This key field is usually a unique identifier for each record in the file. The records are stored in the file sequentially according to the value of the key field.
Advantages of Sequential Access Method
1. Simple to implement: The sequential access method is easy to implement because it does not require any complex data structures or algorithms.
2. Efficient for large files: This method is efficient for large files because the records are stored in a specific order, which makes it easier to retrieve records that are close together.
3. Low cost: The sequential access method is a low-cost method of file organization because it does not require any special hardware or software.
Disadvantages of Sequential Access Method
1. Slow access time: The access time for records in a sequential file is slow because the records have to be read in sequence until the desired record is found.
2. Limited flexibility: This method is not flexible because records cannot be easily inserted or deleted from the file without disrupting the sequential order.
3. Not suitable for frequent updates: The sequential access method is not suitable for files that need to be frequently updated because it requires rewriting the entire file each time a record is added, deleted, or modified.
Conclusion
Sequential access method is a file organization technique in which data records in a file are arranged in a specific order according to a key field. It has advantages such as simplicity, efficiency for large files, and low cost, but also has disadvantages such as slow access time, limited flexibility, and not suitable for frequent updates.

Shanaya Dey answered |
Entity:
An entity, in the context of databases, refers to a real-world object or concept that exists independently. Entities can be tangible, such as a person or a product, or intangible, such as an idea or a transaction. In database management systems (DBMS), entities are typically represented as tables.
Physical Form:
When an entity is present in the real world in a physical form, it means that the entity has a tangible representation that can be interacted with or observed. For example, a person, a car, or a building are all entities that exist in physical form.
DBMS:
A Database Management System (DBMS) is a software system that allows users to interact with a database. It stores, retrieves, and manages data in a structured format. While a DBMS can be used to represent entities in a digital form, the entities themselves exist in the real world in physical form.
Therefore, in the context of this question, the correct answer is Entity as it refers to a thing present in the real world in physical form. While a DBMS is a software system used to manage data, it does not exist in physical form like an entity does.

Value of Beads in Heaven
The correct answer for the value of each bead in heaven is option 'C,' which is 5.
Explanation
This question is a tricky one and requires careful reading. The statement implies that there is some value assigned to the beads in heaven, and the test-taker needs to determine what that value is. However, there is no information given to suggest what that value might be.
The answer to this question requires some lateral thinking. The word "bead" has multiple meanings, and in this case, the intended meaning is likely different from what the test-taker might initially assume. The answer can be found by considering the following:
- The question does not specify what kind of beads are being referred to. This lack of specificity is intentional and suggests that the test-taker should not assume that the beads in question are physical objects.
- The question is phrased as a riddle or puzzle, which implies that there is some wordplay or lateral thinking involved in finding the answer.
- The question is posed as a statement rather than a question, which suggests that the answer is embedded in the statement itself.
With these clues in mind, the answer can be found by considering the statement as a whole. The statement reads: "The value of each bead in heaven is." The final word in the statement is "is," which is a linking verb that suggests that the statement is incomplete. The test-taker must supply the missing information.
The missing information can be found by considering the word "bead" in a different context. In this case, the word "bead" can be interpreted as a homophone for the word "deed." This interpretation is supported by the fact that the word "bead" is capitalized in the question, which suggests that it is being used as a proper noun rather than a common noun.
With this interpretation in mind, the statement can be completed as follows: "The value of each bead in heaven is deeds." In other words, the value of each good deed done on earth is considered to be high in heaven.
Conclusion
The correct answer to the question is option 'C,' which is 5. The question requires lateral thinking and careful reading to arrive at the correct answer. The word "bead" is used as a homophone for the word "deed," which is the missing information that completes the statement. The statement implies that good deeds are considered valuable in heaven.

An attachment is a file that is sent along with an email message by appending itself to the ASCII message. The attachment is transformed into text when sent through the Internet.
The recipient's mail client will then convert this attachment back to original format when it is received.
An email attachment can be any type of file, including images (photos), videos, mp3s, documents, zipped files/folders, and more.Most email providers have a limit on the size of the attachment that can be sent. Also, you can usually only send up to a certain amount of attachments with each email.
Bear these filesize limits in mind when sending attachments, the size of the attachment you are sending may be acceptable by your email provider, but may be too big for the recipient's email account.

Hypertext Markup Language (HTML) is the standard markup language for creating web pages and web applications. With Cascading Style Sheets (CSS) and JavaScript, it forms a triad of cornerstone technologies for the World Wide Web.
Web browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for the appearance of the document.

Explanation:
When a previously saved file is edited, it means that changes have been made to the file. However, these changes are not automatically saved in the file.
To save the changes made to the file, the user must perform the following steps:
1. Select the "Save" option from the "File" menu or use the keyboard shortcut "Ctrl + S" to save the changes made to the file.
2. If the user wants to save the changes as a new file, he/she can select the "Save As" option from the "File" menu and give the new file a different name.
3. If the user tries to close the file without saving the changes, he/she will be prompted to save the changes before closing the file.
Therefore, the correct answer is option 'E' - the file must be saved again to store the changes.

Explanation:
In a database, information should be organized and accessed according to its logical structure. This means that data is arranged in a way that makes sense and is easy to access and use.
Here are some reasons why information should be organized according to its logical structure:
1. Efficient data retrieval: When data is organized logically, it is easier to retrieve and access. This means that users can quickly find the information they need without having to search through large amounts of irrelevant data.
2. Better data analysis: Logical organization also makes it easier to analyze data. For example, if data is organized by date, it is easy to see trends and patterns over time.
3. Improved data quality: Logical organization can also help improve the quality of data. By ensuring that data is consistent and accurate, users can rely on it to make informed decisions.
4. Scalability: Logical organization also makes it easier to scale a database as it grows. As new data is added, it can be organized in a way that makes sense and is easy to access.
In summary, organizing data according to its logical structure is essential for efficient data retrieval, better data analysis, improved data quality, and scalability.

A tutorial on how to multiply binary numbers, along with examples, exercises and answers is presented.
let us first add binary numbers with one digit.
0 x 0 = 0
0 x 1 = 1
1 x 0 = 1
1 x 1 = 1
The above simple additions are similar to those of decimal.
We now multiply numbers with more than one digit: 1 0 1 1 x 1 0 0 1
1) The multiplication of binary numbers is similar to the multiplication of decimal numbers.
1 0 1 1
x
1 0 0 1
____ ____ ____ ____
1 0 1 1
0 0 0 0
0 0 0 0
1 0 1 1
___ ___ ___ ___ ___ ___ ___
1 1 0 0 0 1 1
The multiplication of binary numbers is done by shifting by one bit and adding. It can be easily checked that 1011 which is 11 in decimal multiplied by 1001 which is 9 in binary gives 99 which is 1100011 in binary.

The First Graphical Web Browser: Mosaic
Mosaic is the first graphical web browser that was developed by Marc Andreessen and his team at the National Center for Supercomputing Applications (NCSA) in the United States. It was released in 1993 and quickly became popular due to its user-friendly interface and ability to display images and text on the same page.
Features of Mosaic
- Graphical User Interface: Mosaic was the first web browser to use a graphical user interface (GUI) instead of a command-line interface. This made it easier for users to navigate and browse the web.
- Support for Images: Mosaic was the first web browser to support images, including JPEG and GIF files. This made it possible for web pages to include pictures and graphics, which was not possible with earlier text-based browsers.
- Hypertext Links: Mosaic also introduced hypertext links, which allowed users to navigate between web pages by clicking on hyperlinks. This made it possible to create a web of interconnected pages, which is the basis of the modern World Wide Web.
- Cross-Platform Compatibility: Mosaic was designed to work on a variety of operating systems, including Windows, Mac OS, and Unix. This made it accessible to a wide range of users.
Impact of Mosaic
Mosaic was a game-changer in the evolution of the web. Its user-friendly interface and support for images and hypertext links made the web more accessible and easier to use. It also paved the way for the development of other graphical web browsers, such as Netscape and Internet Explorer. Today, we take for granted the ability to browse the web with graphical browsers, but it was Mosaic that first made this possible.
