Computer System Servicing Nc II (Final Examination)

Keeping your work area clean, organized, and well-lit is important in OHS (Occupational Health and Safety). This is because a clean and organized work area reduces the risk of accidents, such as slips, trips, and falls. It also promotes efficiency and productivity by making it easier to find tools and materials. Additionally, a well-lit work area helps prevent eye strain and fatigue, ensuring a safer and healthier working environment. Therefore, the statement "Keep your work area clean, organized, and well-lit" is true in terms of OHS.

A hard disk is a permanent storage device because it retains data even when the computer is turned off. Unlike volatile storage devices like RAM, which lose data when power is cut off, a hard disk uses magnetic storage to store data on a spinning disk. This allows for long-term storage of files and programs, making it an essential component of most computers.

BIOS stands for Basic Input/Output System. It is a firmware that is built into a computer's motherboard. The BIOS provides the computer with the necessary instructions to start up and initialize the hardware components during the booting process. It also provides a basic set of input/output functions for communication between the operating system and the hardware devices. The BIOS is responsible for tasks such as detecting and configuring hardware, managing power settings, and loading the operating system into memory.

The given correct answer is "Operating System". This is because the master control program in a computer, as mentioned in the question, is the essential program that performs various tasks such as maintaining disk files, running applications, and handling devices. An operating system is responsible for managing all these functions and providing a user-friendly interface to interact with the computer system. Examples of operating systems include Windows 7 and Ubuntu.

An IP address stands for Internet Protocol Address. It is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. The IP address serves two main functions: identifying the host or network interface, and providing the location of the host in the network.

The default IP address in version 4 first octet is 192. This means that in a typical IPv4 address, the first number in the four-part sequence will be 192. This is a commonly used default IP address for many devices and networks.

The given correct answer is F10. The F10 key is commonly used as a shortcut for the "Save and Exit" command in various software applications. Pressing F10 allows users to quickly save their work and exit the current program or dialog box. This shortcut is particularly useful when working on tasks that require frequent saving, such as document editing or programming.

IPv6 is the latest version of IP address. It was introduced to replace the previous version, IPv4, due to the exhaustion of available IPv4 addresses. IPv6 uses 128-bit addresses, allowing for a significantly larger number of unique addresses compared to IPv4's 32-bit addresses. This enables the continued growth of the internet and supports the increasing number of devices connected to it. IPv6 also offers improved security and more efficient routing compared to IPv4.

It is important to not attempt repair work when you are tired in order to ensure safety in the workplace. Fatigue can impair your judgment and reaction time, increasing the risk of accidents and injuries. It is crucial to be alert and well-rested when performing repair work to minimize the chances of making mistakes or overlooking potential hazards.

Windows 7 supports both 32-bit CPUs and 64-bit x64 CPUs. However, the STARTER edition of Windows 7 does not support 64-bit x64 CPUs, while all other editions of Windows 7 do. Therefore, the statement is true.

The core of the system in the context of the system unit is the Central Processing Unit (CPU). The CPU is the primary component responsible for executing instructions and performing calculations, serving as the "brain" of the computer. While memory (option A) and the motherboard (option B) are crucial components, the CPU is often considered the core processing unit that performs the majority of the computing tasks.

The default browser in Ubuntu Operating System is Mozilla Firefox.

The percentage in partitioning Windows 7 Operating System is 40% and 60%. This means that when partitioning the Windows 7 OS, 40% of the space will be allocated to one partition and 60% will be allocated to another partition. This allows for a balanced distribution of resources and storage capacity between the two partitions.

Vienna was the code name for the Windows 7 operating system. This code name was used during the development phase of Windows 7 before it was officially released. Windows 7 was the successor to Windows Vista and was a major improvement over its predecessor. It introduced several new features and enhancements, such as a redesigned taskbar, improved performance, and better compatibility with hardware and software.

To prevent accidental static charges to the components during the disassembly procedure, it is necessary to first touch a grounded portion of the chassis. This helps to discharge any static electricity that may have built up in the body before coming into contact with the components. By grounding oneself, the risk of damaging sensitive electronic components due to static discharge is minimized. Holding the power cable and using an ESD protection kit are also important precautions to take, but the first step of grounding oneself is crucial to ensure the safety of the components.

The given IP address in binary form is 0010 0110 1101 1011. To convert it to hexadecimal, we can group the binary digits into sets of 4 and convert each set separately. The first set, 0010, is equal to 2 in decimal and 2 in hexadecimal. The second set, 0110, is equal to 6 in decimal and 6 in hexadecimal. The third set, 1101, is equal to 13 in decimal and D in hexadecimal. The fourth set, 1011, is equal to 11 in decimal and B in hexadecimal. Therefore, the hexadecimal representation of the given IP address is 26DB.

The given answer lists the different versions of Windows 7, starting with the "Starter" edition and followed by "Home Basic". This suggests that the question is asking for the correct order of the Windows 7 versions mentioned.

During the assembly or power-up of the system unit, it is important to avoid loose screws inside the unit as they can cause damage or interfere with the components. Taking care of insulators is necessary to prevent electrical shorts and protect the system. Securing all connections ensures proper functioning and prevents any loose or disconnected components. Lastly, it is important to avoid shortening the header with the power supply connector to prevent any electrical damage.

The given IP address 75.77.9.8 when converted to binary 8 bit is 1001011010011010000100100001000.

The given IP address, 92.68.6.2, when converted to binary, is represented as 01011100.01000100.00000110.00000010 

The given answer is incorrect. The question asks for two types of application software that install using a simulator. However, Microsoft Office, Klite, and Adobe Reader are not examples of application software that install using a simulator. They are commonly used software applications, but they do not require a simulator for installation.

The given answer provides two types of open-source operating systems: Linux and Ubuntu. Linux is a widely used open-source operating system that is known for its stability, security, and flexibility. Ubuntu is a popular Linux distribution that is user-friendly and comes with a variety of pre-installed software. The answer also includes Zorin Operating System, Robolinux, StartOS, and Zorin OS, which are additional examples of open-source operating systems.
