CompTIA A+ Preparation Part 2

WUXGA stands for Wide Ultra Extended Graphics Array, and it has a maximum resolution of 1900 x 1200. This resolution refers to the number of pixels displayed horizontally and vertically on a screen. Therefore, WUXGA can display a maximum of 1900 pixels horizontally and 1200 pixels vertically, resulting in a high-quality and detailed image.

Disabling automatic restart on system failure will prevent the computer from automatically rebooting when it crashes. This will allow Carol to see the error message that appears on the screen, which can help in diagnosing and resolving the problem with her Windows Vista computer.

Rebooting a computer after a software error is done to clear the memory and start fresh. When a software error occurs, it can cause the computer's memory to become corrupted or overloaded. By rebooting, the computer clears out any lingering issues in the memory and restarts with a clean slate. This can help resolve the software error and allow the computer to function properly again.

Chkdsk is a utility that can be used to check the hard drive for physical errors. It scans the file system and the physical disk surface to detect and fix any errors that may be present. It is commonly used to diagnose and repair issues related to the hard drive, such as bad sectors or corrupted files. Disk Search, Fixboot, and Disk Defragmenter are not specifically designed to check for physical errors on the hard drive.

Disk Defragmenter is the correct answer because it is the utility that rearranges fragmented files on a disk to make them contiguous. Fragmentation occurs when files are broken up into smaller pieces and stored in non-contiguous blocks on the disk. This can slow down the computer's performance as it takes longer to access the fragmented files. Disk Defragmenter helps to optimize disk performance by rearranging the files and placing them in contiguous blocks, making them easier and faster to access.

A touchpad is a built-in pointing device on most laptops that allows users to control the cursor by moving their finger across a flat surface. It is an alternative to a traditional mouse and provides a convenient and compact solution for navigating and interacting with the computer. The touchpad is sensitive to touch and gestures, allowing users to perform various actions such as clicking, scrolling, and zooming without the need for an external mouse.

SATA stands for Serial Advanced Technology Attachment. This is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives and solid-state drives. It is used to transfer data between the computer's motherboard and storage devices.

When you first power on a computer, it runs a diagnostic program called POST (Power-On Self Test) that is built into the BIOS (Basic Input/Output System). This test checks the hardware components of the computer to ensure they are functioning properly before the operating system is loaded. POST helps identify any potential issues or errors that may prevent the computer from starting up correctly.

The correct connector that plugs into a Network Interface Card (NIC) is RJ-45. RJ-45 connectors are commonly used for Ethernet connections and are designed to connect network cables to devices such as computers, routers, and switches. They have eight pins and are larger than RJ-11 connectors, which are used for telephone connections. USB connectors are used for connecting peripheral devices to computers, and STP (Shielded Twisted Pair) refers to a type of cable used for network connections, not a connector itself.

USB mice are designed to be hot-swappable, which means they can be plugged and unplugged while the computer is running without causing any damage or requiring a restart. Therefore, the correct action to take in this situation is to simply plug the mouse back in.

If Plug and play doesn't recognize a new device plugged into the system, the Control Panel utility that can be used to install it is Add/Remove Hardware. This utility allows the user to manually add or remove hardware devices from the system. It helps in detecting and installing new devices that may not be recognized by the Plug and Play feature. The Administrative Tools, Security Center, and Power Options do not have the specific functionality to install new hardware devices.

Rebooting the computer can help resolve the issue of the computer being locked up. Having multiple programs running simultaneously, such as the spreadsheet, word processing program, email, and streaming a radio station, can overload the computer's resources and cause it to freeze. By rebooting the computer, it clears the memory and allows the computer to start fresh, potentially resolving the issue.

The correct answer is "Pixels". The screen's resolution refers to how many pixels are used to draw the screen. Pixels are the smallest units of color and light that make up an image on a screen. The more pixels there are, the higher the resolution and the sharper and more detailed the image will appear.

Worn pick up rollers can be a common cause of paper jams in a laser printer. Over time, the pick up rollers can become smooth and lose their grip, making it difficult for them to properly feed the paper into the printer. This can result in the paper getting stuck or jammed in the printer.

The given correct answer is PING. PING is a command prompt tool that sends out four 32-byte packets to a specified destination and waits for a reply. It is commonly used to test the connectivity between two devices on a network.

A KVM switch is the correct piece of equipment that will allow the set-up to work. A KVM switch stands for Keyboard, Video, and Mouse switch. It allows multiple computers to be controlled using a single keyboard, mouse, and monitor. By connecting the computers to the KVM switch and then connecting the switch to the monitor, users can easily switch between the computers and control them using the same peripherals. This is a convenient solution for managing multiple computers with limited space and resources.

During the startup process in Windows XP, pressing the F8 key allows access to the advanced startup options. These options include Safe Mode, Last Known Good Configuration, Debugging Mode, and other troubleshooting options. Pressing the spacebar when prompted or entering the ASR (Automated System Recovery) are not correct ways to access the advanced startup options in Windows XP. Administrative tools are a separate set of tools and settings in Windows XP, and they are not directly related to the advanced startup options.

Both compression and encryption can be used on a file or folder. Compression is the process of reducing the size of a file or folder, making it easier to store or transfer. Encryption, on the other hand, is the process of converting data into a code, making it unreadable to unauthorized users. Both techniques can be applied to files or folders to enhance security and efficiency.

The correct answer is "Ping". The Ping command is used to test connectivity between two devices on a network. It sends a small packet of data to the specified destination and waits for a response. If a response is received, it indicates that there is connectivity between the two devices. This command is commonly used to troubleshoot network connectivity issues and to measure the round-trip time (RTT) between devices.

File names are not case-sensitive in most operating systems. This means that whether a file name is written in uppercase or lowercase letters does not affect the ability to access or open the file. For example, a file named "document.txt" can be accessed by typing "document.txt" or "DOCUMENT.TXT". However, it is important to note that some operating systems, such as Linux, do treat file names as case-sensitive.

MAC filtering is a security feature that allows the router to only allow access to devices whose MAC addresses have been registered. MAC addresses are unique identifiers assigned to each network device. By enabling MAC filtering, the router will only grant network access to devices whose MAC addresses have been pre-approved. This helps to prevent unauthorized devices from connecting to the wireless network.

The flickering on a CRT monitor is usually caused by a low refresh rate. By increasing the refresh rate to a higher value (Hz), the monitor will update the image more frequently, reducing or eliminating the flickering effect.

In a school environment, blocking access to the internet is important to ensure that students do not get distracted or access inappropriate content. Port number 80 is the default port for HTTP, which is used for accessing websites. By blocking port 80, all web traffic will be blocked, effectively preventing access to the internet.

Throttling refers to the process of slowing down the processor in order to conserve power. This technique is commonly used in electronic devices to reduce power consumption and extend battery life. By reducing the processing speed, the device can operate at a lower power level, resulting in energy savings. Throttling is a useful feature in devices such as smartphones and laptops, where power efficiency is crucial. It helps to balance performance and power consumption, allowing users to get the most out of their devices while optimizing battery life.

Network-based firewalls are typically used to protect companies from public networks. These firewalls are installed at the network perimeter and monitor incoming and outgoing traffic. They can filter and block specific types of traffic based on predefined rules, such as blocking certain IP addresses or ports. Network-based firewalls provide an additional layer of security by controlling access to the company's internal network and preventing unauthorized access from external sources.

Solid-state drives (SSDs) are based on flash memory and are set to replace conventional hard disk drives (HDDs). SSDs offer faster access times, lower power consumption, and higher durability compared to HDDs. They have no moving parts, making them more resistant to physical damage and less prone to failure. SSDs are increasingly being used in laptops, desktops, and servers due to their improved performance and reliability.

The correct answer is 1Gbps because 1000BaseT is a type of Ethernet technology that supports a maximum data transfer rate of 1 gigabit per second (Gbps). This means that it can transmit data at a speed of 1 billion bits per second, which is significantly faster than the other options listed (100Mbps, 10Mbps, and 1024KBPS).

The "Print Over run" error indicates that the printer's buffer memory, which temporarily stores the data to be printed, is not sufficient to handle the large report. Increasing the RAM memory installed in the computer will provide more space for the printer's buffer, allowing the large report to be printed without encountering the error. Installing a bigger hard drive or using bigger sheets of paper will not address the issue of insufficient buffer memory. Reinstalling a corrupted driver may resolve other printing issues, but it will not specifically fix the "Print Over run" error.

In the services console, you can indeed see what dependencies a service has as well as what services depend on the particular service. This allows users to understand the relationships and connections between different services, providing a comprehensive view of the dependencies within the system.

The correct answer is that the computer was not hooked up to the network and did not receive the answer file. This means that the computer was unable to access the necessary resources and instructions for the unattended installation process. As a result, it was unable to progress beyond the first user interaction prompt.

The correct answer is "Cleaning, Charging, Writing, Developing, Transferring, Fusing." In the laser printing process, the first step is cleaning the drum or the imaging surface to remove any residual toner or debris. Then, the drum is charged with an electrostatic charge. After that, the laser beam writes the image or text onto the drum by selectively removing the charge. Next, the developing unit applies toner to the charged areas on the drum, creating a visible image. The image is then transferred onto the paper through a combination of heat and pressure in the fusing process.

A small paging file size can cause the system to run extremely slow and constantly access the hard drive. The paging file, also known as the virtual memory, is used by the computer to temporarily store data that cannot fit in the RAM. When multiple programs are being run, the system may need to constantly swap data between the RAM and the paging file, leading to increased hard drive activity and slower performance. Increasing the paging file size can help alleviate this issue.

A thermal printer is the correct answer because it uses heat to transfer an image or text onto special waxy paper that comes on a roll. This type of printer is commonly used in industries such as retail and logistics for printing labels, receipts, and barcodes. The heat from the printer's thermal head causes the special paper to react and produce the desired printout. Unlike other printers, a thermal printer does not require ink or toner cartridges, making it a cost-effective and low-maintenance option for certain printing needs.

The two standards of laptop memory form factors are SoDIMM and MicroDIMM. SoDIMM stands for Small Outline Dual In-Line Memory Module and is a smaller version of the DIMM form factor used in desktop computers. MicroDIMM, on the other hand, is an even smaller form factor primarily used in ultra-compact laptops and other small form factor devices. These form factors allow for the installation of memory modules in laptops, providing the necessary storage and performance capabilities.

The correct answer is that the function key is stuck on. This is indicated by the fact that most of the keys don't respond at all and the ones that do only change the volume settings, dim and brighten the screen, and change the screen to an external display. When the function key is stuck on, it can cause the keyboard to behave in this way, as the function key is designed to modify the behavior of other keys when pressed in combination with them.

The purpose of using a thermal compound is to create a contact surface between the processor and the heatsink. This helps to improve heat transfer by filling in any microscopic gaps or imperfections on the surfaces of the processor and heatsink. By ensuring better contact, the thermal compound helps to dissipate heat more efficiently, preventing the processor from overheating.

The correct answer is 802.11. The 802.11 standard is used for wireless local area networks (WLANs). It specifies the protocols and technologies for wireless communication, including data transfer rates, frequency bands, and security measures. This standard is commonly known as Wi-Fi and is widely used for wireless internet access in homes, offices, and public spaces.

The correct answer is 100m. The 10baseT standard, which is a type of Ethernet networking, has a maximum distance limit of 100 meters. This means that the cable used for this standard can transmit data effectively up to a distance of 100 meters. Beyond this distance, the signal may weaken and cause data transmission issues.

Windows file naming conventions allow for names up to 255 characters in size. This means that when naming a file in Windows, you can use up to 255 characters for the file name, including letters, numbers, spaces, and special characters. This allows for more descriptive and detailed file names, making it easier to organize and find files on a Windows system.

Docking stations are different from port replicators because they have the capability to include permanent components such as hard drives and act as an extension of the motherboard. This means that docking stations not only provide additional ports for connecting peripherals, but also have the ability to enhance the functionality and storage capacity of the device they are connected to. In contrast, port replicators are primarily used to replace damaged or non-working ports on a device, without offering any additional features or components.

The correct answer is one and a half times the amount of RAM in the system. Windows sets the default size for virtual memory to be 1.5 times the amount of RAM in the system. This is done to ensure that there is enough virtual memory available for the system to use when the physical RAM is fully utilized. By setting the virtual memory size to be larger than the physical RAM, it allows the system to use the hard drive space as additional memory when needed.

The three options on the Windows XP main setup screen are Repair a Windows XP installation, Quit setup, and Set up Windows XP. These options allow the user to either repair an existing installation, exit the setup process, or proceed with setting up a new installation of Windows XP.

A DHCP server provides the IP address, DNS server address, subnet mask, and default gateway address to a computer. These pieces of information are necessary for the computer to establish a network connection and communicate with other devices on the network. The IP address is the unique identifier assigned to the computer, the DNS server address is used for domain name resolution, the subnet mask determines the network boundaries, and the default gateway address is the IP address of the router that connects the local network to the internet.

An armored virus is a type of virus that is specifically designed to make it difficult for antivirus software to detect or analyze. It achieves this by employing various techniques such as encrypting its code, using self-modifying code, or disguising itself within legitimate files. By doing so, it can evade detection and continue to infect systems. Therefore, an armored virus is a virus that covers itself in protective code to avoid detection and analysis.

To prevent the UAC from prompting you when opening a specific program every time, you need to right-click the program icon, choose properties, go to the compatibility tab, and click on "Run this program as an administrator". This will allow the program to run with administrative privileges, bypassing the UAC prompt.

A MAC address is a unique identifier assigned to network interfaces for communication on a network. The correct format for a MAC address is usually six groups of two hexadecimal digits separated by hyphens or colons. In this case, the correct format is 45-67-70-C8-4G-DE.

The minimum processor speed for all versions of Vista is 800 Mhz. This means that any computer running Vista must have a processor that is at least 800 Mhz in speed.

Normal backup is a type of backup that backs up selected files and clears the archive bit. This means that after performing a normal backup, the archive bit is reset for all the files that were backed up, indicating that they have been successfully backed up. This type of backup is commonly used as a baseline backup and is typically performed on a regular basis to ensure that all selected files are backed up and can be restored if needed.

Bus, Ring, and Mesh network topologies can be both logical and physical. In a Bus topology, all devices are connected to a single cable, creating a logical and physical connection. In a Ring topology, devices are connected in a circular manner, forming a logical and physical loop. In a Mesh topology, devices are connected to each other directly, creating both logical and physical connections between them.
