Frage 1 Bericht
What is considered the brain of the computer?
Antwortdetails
The brain of the computer is considered to be the "Central Processing Unit" (CPU). The CPU is the primary component of a computer that performs most of the processing and calculations required to run programs and applications. It is responsible for executing instructions and controlling the operations of the computer's other hardware components, such as the memory, input/output devices, and storage devices. The CPU is often referred to as the "brain" of the computer because it performs many of the same functions that the human brain does, such as processing information, making decisions, and controlling the body (or in the case of the computer, the hardware components). It is located on the motherboard of the computer, and it consists of a small chip that contains millions of transistors and circuits that work together to perform calculations and operations at incredible speeds. While the monitor/display screen, mouse, and printer are all important components of a computer system, they do not serve the same function as the CPU. The monitor/display screen displays the output from the computer, the mouse is an input device used to control the cursor on the screen, and the printer is a device used to produce hardcopy output from the computer.
Frage 2 Bericht
In which situation does running application remain active?
Antwortdetails
When a computer application is running, it is stored in the computer's memory, which allows it to continue functioning as long as it is needed. In the case of logging off, shutting down, or rebooting the computer, all applications currently running on the system are closed or terminated. Therefore, the running application would not remain active in any of these situations. However, in the case of a user switching, the running application can remain active. This is because when a user switches on a computer that is running, the operating system creates a new user session while keeping the current user's session active. In this scenario, the running application would continue to function within the current user's session, while the new user session would be independent and have its own set of applications and processes. Therefore, the running application would remain active when the user is switched.
Frage 3 Bericht
Which program translates programs to a simpler language that the computer can execute.
Antwortdetails
The program that translates programs to a simpler language that the computer can execute is called a compiler. A compiler is a program that takes the source code of a program written in a high-level programming language and translates it into machine code or executable code that the computer can understand and execute. The process of compiling involves several steps, including lexical analysis, syntax analysis, semantic analysis, code optimization, and code generation. When a programmer writes a program in a high-level programming language such as Java or Python, the code is not directly executable by the computer. Instead, the code must be translated into machine code, which is a low-level language that the computer can understand and execute. This is where the compiler comes in. The compiler takes the source code written in the high-level programming language and converts it into machine code that can be executed by the computer. The advantage of using a compiler is that the resulting executable code is usually faster and more efficient than code interpreted by an interpreter, which we will discuss next. Additionally, since the code is already translated into machine code, it can be executed multiple times without the need for further translation, making it faster to execute. Overall, a compiler is a program that translates high-level programming code into machine code that a computer can execute, allowing programmers to write code in a more human-readable language and then have it translated into a language that the computer can understand and execute.

Frage 6 Bericht
Encryption helps with what?
Antwortdetails
Encryption helps with safe delivery of messages to their destination without being accessed by a third party. Encryption is a process of converting plain text into coded or scrambled text so that only authorized parties who have the key can access and understand the original message. This means that even if an unauthorized person intercepts the message during transit, they cannot read or understand it because it is encrypted. Encryption is commonly used to protect sensitive data such as passwords, credit card numbers, and personal information when it is transmitted over the internet. It also helps to protect confidential business or government communications from hackers, cybercriminals, and other unauthorized third parties. Therefore, encryption helps to ensure that messages are delivered safely and securely to their intended recipients without being accessed or intercepted by unauthorized parties.
Frage 7 Bericht
Which of the following system software resides in the main memory always?
Antwortdetails
The system software that always resides in the main memory is the Operating System (OS). In many operating systems, the loader resides permanently in memory. The OS manages the resources of the computer and acts as an interface between the user and the hardware. It is responsible for tasks such as memory management, process management, file management, and input/output operations. Text editors, assemblers, linkers, and loaders are all types of system software, but they do not always reside in the main memory. They are typically loaded into memory when needed, and can be swapped out of memory when other processes need more memory. This is because main memory is a limited resource and the OS dynamically allocates it to different processes as needed.
Frage 8 Bericht
What is the full form of UDP?
Antwortdetails
The full form of UDP is User Datagram Protocol. It is a communication protocol used for sending and receiving data over the internet. UDP is a lightweight, connectionless protocol that operates at the Transport layer of the Internet Protocol (IP) suite. Unlike TCP (Transmission Control Protocol), which guarantees delivery of data, UDP does not provide any guarantees regarding delivery or sequencing of packets. Instead, UDP is often used for applications that require faster data transfer, such as video streaming or online gaming, where small amounts of lost data are acceptable. The "User Datagram" part of the name refers to the fact that UDP sends data in the form of datagrams, which are discrete chunks of data that are sent as individual packets. The "Protocol" part of the name indicates that UDP is a set of rules and procedures that govern how data is transmitted and received over a network. In summary, UDP is a fast and lightweight protocol used for sending data over the internet. Its name reflects the fact that it operates using datagrams and is a protocol for communication.

Computers are versatile machines that can perform a wide variety of tasks, including playing games, streaming videos, accessing news and other information, and connecting with others on social media platforms. While some computers may be designed or optimized for certain types of tasks, such as gaming or video editing, all computers are capable of handling entertainment, information, and social media to some extent. Therefore, the answer to this question is that there is no option that describes something a computer cannot be used for among the given choices.
Frage 11 Bericht
Files that maintain the hierarchical structure of the file system.
Antwortdetails
The correct answer is "Directories." Directories are special files that organize the hierarchical structure of the file system by grouping related files together into named collections. They act like folders, allowing users to easily locate and access the files they need. Each directory can contain other directories (sub-directories) and files. For example, in a Windows system, the "C:\Users" directory contains a sub-directory for each user account on the computer, and each user account directory contains sub-directories for documents, pictures, music, etc. In short, directories allow us to maintain a structured and organized file system.
Frage 12 Bericht
What is the permanent memory built into your computer called?
Antwortdetails
The permanent memory built into a computer is called ROM (Read-Only Memory). It is called "read-only" because, unlike RAM (Random Access Memory), which can be written to and rewritten, the information stored in ROM cannot be changed by the computer or the user. ROM is a type of memory that is built into the computer's hardware and contains the basic instructions that the computer needs to boot up and run its basic functions. These instructions are often referred to as the "firmware" of the computer, and include the BIOS (Basic Input/Output System) that controls the startup process, as well as other low-level software that interacts directly with the computer's hardware. CD-ROM, on the other hand, is a type of storage medium that can be used to store data or programs, but it is not built into the computer itself. CDs and DVDs can be used to store data, programs, or other types of media, but they are not considered a type of permanent memory built into the computer.
Frage 13 Bericht
A 2-input gate that can be used to pass a digital waveform unchanged at certain times and inverted at other times is ___________
Antwortdetails
The 2-input gate that can be used to pass a digital waveform unchanged at certain times and inverted at other times is the XOR (exclusive OR) gate. An XOR gate has two input signals and one output signal. The output is HIGH (1) if the two input signals are different, and LOW (0) if the two input signals are the same. In other words, an XOR gate produces an output signal that is the "exclusive or" of its two input signals. When one of the input signals is held at a constant logic level (either HIGH or LOW), the XOR gate can be used to pass the other input signal unchanged or inverted, depending on the value of the constant signal. If the constant signal is HIGH, the output signal will be inverted; if the constant signal is LOW, the output signal will be unchanged. This property of the XOR gate makes it useful in digital electronics for a variety of applications, such as data encryption, error detection and correction, and clock synchronization.

This is how devices on the internet communicate with each other.
Frage 17 Bericht
Which key deletes text?
Antwortdetails
The key that deletes text is the backspace key. When you type, the characters you enter are added to the right of the cursor, which shows you where the next character will be inserted. If you want to delete a character, you can move the cursor to the left of that character using the arrow keys, and then press the backspace key. This will remove the character to the left of the cursor. You can also use the backspace key to delete a selection of text. To do this, you first need to highlight the text you want to delete by clicking and dragging the cursor over it. Once the text is highlighted, you can press the backspace key to delete it. In summary, the backspace key is used to delete characters to the left of the cursor or to delete a selected portion of text.
Frage 18 Bericht
Binary coded decimals (BCD) numbers express each digit as a ___________
Antwortdetails
Binary coded decimals (BCD) numbers express each digit as a nibble. A nibble is a group of 4 bits, which can represent 16 distinct values (0-15). In BCD, each decimal digit is encoded using a separate nibble, where each nibble represents the binary equivalent of the digit. For example, the decimal number 123 would be represented in BCD as four nibbles: 0001 (1), 0010 (2), 0011 (3), and 0011 (3). Using a nibble to represent each digit is a simple and efficient way to encode decimal numbers in binary form. BCD is commonly used in computer systems where decimal arithmetic is required, such as in financial calculations or in control systems where numerical values need to be displayed on digital screens. In summary, BCD numbers express each decimal digit as a nibble, allowing for efficient and accurate representation of decimal numbers in binary form.

While it may be possible to play movies or music within Internet Explorer, its primary purpose is to browse the internet and display web pages.
Frage 20 Bericht
Storage which retains data after power cut off is called.
Antwortdetails
The type of storage that retains data even when the power is turned off is called non-volatile storage. Non-volatile storage is different from volatile storage, which loses all data when the power is turned off. To help you understand the difference, imagine that you have two types of memory: a whiteboard and a notebook. The whiteboard is like volatile memory because anything you write on it will disappear as soon as you erase it or turn off the lights. On the other hand, the notebook is like non-volatile memory because anything you write in it will remain there until you deliberately erase or destroy it. Similarly, non-volatile storage, such as hard drives, solid-state drives (SSDs), and flash drives, can retain data even when the power is turned off. This is because the data is stored using physical means that do not require an electrical charge to be maintained. In contrast, volatile storage, such as RAM, loses all data when the power is turned off because the data is stored using electrical charges that require a constant supply of power to be maintained. Overall, non-volatile storage is essential for long-term data storage because it can retain data even in the absence of power, whereas volatile storage is useful for short-term storage of data that does not need to be preserved beyond the current session or power cycle.
Frage 21 Bericht

Antwortdetails
Document readers are devices or software programs that can analyze and interpret written or printed text on a document. These devices can read different types of data from documents such as marks, handwritten and printed characters, and printed lines. Marks can include things like checkmarks or ticks that people might use to indicate a selection on a form or questionnaire. Handwritten characters are any letters, numbers or symbols that are written by hand, whereas printed characters are those that are produced by a printer. Printed lines refer to the lines of text that are printed on a page. Therefore, the correct answer is "all of the above" as document readers can read all of these types of data from documents.
Frage 22 Bericht
Which number base system is used by low level languages
Antwortdetails
Low level languages, such as Assembly, C, and C++, use binary as the number base system. In a binary system, numbers are represented using only two digits: 0 and 1. This is in contrast to decimal, which uses 10 digits (0-9), or hexadecimal, which uses 16 digits (0-9 and A-F). Binary is used in low level languages because computers use binary internally to store and process data. At the lowest level, computer hardware operates using two states, on and off, which can be represented by binary digits. This makes binary a natural choice for low level programming languages that interact directly with the computer's hardware.

Frage 25 Bericht
What is the function of firewall?
Antwortdetails
A firewall is a type of cybersecurity tool that helps protect a computer or network from unauthorized access or malicious activity from the internet. Think of a firewall as a security guard that stands at the entrance to your network, examining all incoming and outgoing traffic. It examines each packet of data to see if it meets certain criteria, such as the source and destination of the data, and the type of data being transmitted. If the packet meets the criteria, it's allowed to pass through the firewall and reach its destination. If it doesn't meet the criteria, the firewall blocks the packet, preventing it from entering your network. A firewall can help prevent attacks like hacking, malware infections, and other cyber threats that could compromise your data or network. Firewalls can also be configured to filter out certain types of traffic or limit access to certain resources, providing an additional layer of protection for your network. In summary, a firewall is a vital cybersecurity tool that acts as a barrier between your network and the internet, helping to keep your data and devices safe from cyber threats.

Compound Unit: This term does not have a widely recognized meaning in the field of computing or technology in general. However, "compound" can refer to something that is made up of multiple parts, so in some cases, "CU" could be used to refer to a unit that is composed of several components. 2. Communication Unit: In some contexts, "CU" may refer to a Communication Unit. This could be a device or module that is responsible for handling communication between different components or systems, such as transmitting data between a computer and a peripheral device like a printer or scanner. 3. Computer Unit: "CU" could also refer to a Computer Unit, which may be a standalone computer or a component within a larger computer system. In this case, "CU" would generally refer to the main processing unit that is responsible for executing instructions and performing calculations. 4. Control Unit: In the context of computer architecture, "CU" most commonly stands for Control Unit. The Control Unit is a component within the CPU (Central Processing Unit) of a computer that is responsible for coordinating the flow of data between different parts of the CPU and executing instructions. The Control Unit is sometimes referred to as the "brain" of the CPU, as it is responsible for coordinating and directing the operations of the computer. So, to answer the question of what the full form of "CU" is, we would need to know the specific context in which the term is being used.
Frage 27 Bericht
In the files, if order of operation on two or more files are similar, then operation will be
Antwortdetails
If the order of operation on two or more files is similar, then the operation will be sequential. Sequential operation means that the files will be processed one after the other in the same order as specified. For example, if we have two files A and B, and we want to perform the operations 'read', 'process', and 'write' on them in the order A->B, then the program will first read file A, process it, write the result, then move on to file B, read it, process it, and write the result. On the other hand, if the order of operation is not similar, the operation may be more complex or combinational. In that case, the files may be processed in a different order or simultaneously, which may require more complex programming logic. Therefore, having a similar order of operation on multiple files simplifies the programming and makes it more straightforward.

Frage 33 Bericht
A permanent memory, which has data and instruction to start up the computer and does not erase data after power off.
Antwortdetails
The permanent memory that has data and instructions to start up the computer and does not erase data after power off is called ROM (Read-Only Memory). ROM is a type of computer memory that is pre-programmed with data and instructions during manufacturing. This means that once the data and instructions are written into ROM, they cannot be changed or erased, hence the name "read-only". When you turn on your computer, the CPU (central processing unit) looks to the ROM for the instructions on how to boot up the computer. These instructions include basic input/output system (BIOS) code that checks the hardware components to make sure they are working properly, and then loads the operating system from the hard drive or another storage device. The data and instructions stored in ROM are not affected by power outages or restarts, meaning that they are retained even when the computer is turned off. This is why ROM is called non-volatile memory. In summary, ROM is a type of permanent memory that contains data and instructions to start up a computer and does not lose this information when the computer is turned off.
