The image shows an RJ-45 connector. RJ-45 connectors are commonly used for Ethernet connections. They have eight pins and are larger in size compared to RJ-11 connectors, which are typically used for telephone connections and have only four pins.

This network is a star network because each computer is connected to a central device, similar to how the points of a star radiate out from a central point. In a star network, all communication between computers goes through the central device, which helps to manage and control the flow of data. This type of network is commonly used in homes and small businesses, as it allows for easy management and troubleshooting.

This network is a ring network because all computers in the network are connected in a closed loop. In a ring network, each computer is connected to exactly two other computers, forming a circular pathway for data to travel. This type of network is commonly used in situations where data needs to be transmitted in a specific order or where redundancy is important.

The internet is a WAN (Wide Area Network) because it connects multiple networks across a wide geographical area. It allows users to access information and communicate with others globally. A WAN typically uses various communication technologies, such as telephone lines, fiber optics, or satellite connections, to transmit data over long distances. The internet, being a global network of interconnected networks, fits the definition of a WAN.

A purple PS/2 is a keyboard, green is for a mouse.

If the keyboard and mouse are accidentally plugged into the wrong PS/2 ports, they won't work. This is because each PS/2 port is designed for a specific device, with the purple port typically being for the keyboard and the green port for the mouse. Plugging them into the wrong ports will prevent the computer from detecting and recognizing the devices, resulting in their failure to work.

Sata cables only have one connector so they dont need jumpers

Because of its sensibility to light, a drum is in the bag.

Had a computer come through today with boot problems. During the first boot windows wouldn’t load and the second boot it wouldn’t even go through POST. Turns out the network card hadn’t been screwed to the case and the card had come loose.

Turning on MAC address filtering checks the MAC address of the computer connecting to a network. MAC address filtering is a security feature that allows or denies network access based on the MAC address of the device. By enabling this feature, only devices with approved MAC addresses are allowed to connect to the network, providing an additional layer of protection against unauthorized access.

The correct answer is "Media Access Control." In computer networking, a MAC address is a unique identifier assigned to a network interface card (NIC) by the manufacturer. It is used to identify devices on a network at the data link layer of the OSI model. The term "Media Access Control" refers to the process of controlling access to a shared communication medium, such as a network cable, to avoid data collisions between devices.

Sometimes it’s not a 1 but a mark, either way it shows what way the IDE cable should be plugged in. The red wire on the cable should match where the mark or number is.

The correct answer is 11Mbs because 802.11b is a wireless networking standard that operates at a maximum data rate of 11 megabits per second (Mbs). This standard was one of the earliest versions of Wi-Fi and while it offered slower speeds compared to later standards, it was still capable of providing sufficient connectivity for basic internet browsing and email usage.

This type of question is very likely to appear on the essentials test, be sure to know what the topologies look like visually.

The key pushed depends on the motherboard manufactorer which can get annyoing, especially on laptops.

This network is a mesh network because each computer is connected to every other computer in the network. In a mesh network, there are multiple paths for data to travel, allowing for redundancy and increased reliability.

The correct answer is that the fuser is malfunctioning. The fuser is responsible for melting the toner powder onto the paper, and if it is not functioning properly, the toner powder will not adhere correctly and will appear as loose powder on the page.

VGA stands for Video Graphics Array. It is a display standard that was introduced by IBM in 1987. VGA provides a resolution of 640x480 pixels and supports a wide range of colors. It became a popular standard for computer monitors and video cards, and was widely used until the late 1990s. The other options, Video Graphics Accelerator, Video Graphics Account, Video Graphics Application, and Video Graphics Acumination, are not correct definitions for VGA.

BTX was meant to replace ATX but it never took off.

RAID 0, also known as striping, combines multiple physical drives into a single logical drive. This increases the overall storage capacity and improves performance by distributing data across multiple drives simultaneously. However, RAID 0 does not provide any data redundancy or fault tolerance. If any drive fails, the entire array may become inaccessible or lose data. Therefore, it is important to regularly back up data when using RAID 0.

A directory and a folder are indeed the same thing. Both terms are used interchangeably to refer to a container that can hold files or other directories/folders within it. In computer systems, directories are used to organize and manage files, providing a hierarchical structure for easy navigation and storage. Whether you call it a directory or a folder, it serves the same purpose of organizing and storing files.

The domain controller is responsible for responding to authentication requests. It verifies the identity of users and allows them access to the network resources based on their credentials. By authenticating users, the domain controller ensures that only authorized individuals can access sensitive information and resources within the network.

IEEE stands for the Institute of Electrical and Electronics Engineers. This organization is a professional association that focuses on advancing technology in the fields of electrical engineering, electronics, telecommunications, computer science, and related disciplines. The IEEE provides a platform for professionals to collaborate, share knowledge, and develop standards to drive innovation and technological advancements in these areas.

802.11b has a speed of 11Mbs while the others go at 54Mbps

IP (Internet Protocol) is on the Network layer of the OSI model. The Network layer is responsible for routing and forwarding data packets between different networks. IP provides the addressing and routing functions necessary for data to be sent from one network to another. It determines the best path for data transmission, handles packet fragmentation and reassembly, and ensures reliable delivery of data across the network. Therefore, IP is placed on the Network layer of the OSI model.

1284 is a parallel and 1294 is firewire. This is important to remember as some have said that the essentials exam refer to these by their numbers rather than their names.

Layer 7 of the OSI model is the application layer, which is responsible for providing network services to user applications. DHCP (Dynamic Host Configuration Protocol) is a network protocol used for automatically assigning IP addresses to devices on a network. FTP (File Transfer Protocol) is a standard network protocol used for transferring files between a client and a server. HTTP (Hypertext Transfer Protocol) is the protocol used for transmitting web pages over the internet. SMTP (Simple Mail Transfer Protocol) is a protocol for sending email messages. Therefore, all of the options mentioned (DHCP, FTP, HTTP, and SMTP) are found on Layer 7 of the OSI model.

RAID 3 stripes at a byte level and RAID 4 at a block.

Computers need diskspace to complete a job, the amount depends on the size of the file being printed.

This card would go into the AGP slot. AGP stands for Accelerated Graphics Port, which is a high-speed point-to-point channel for attaching a graphics card to a computer's motherboard. AGP slots were commonly used in older computers for graphics cards before being replaced by PCIe slots.

WQXGA stands for Wide Quad Extended Graphics Array, which is a display resolution of 2560 x 1600 pixels. Therefore, the statement "WQXGA is 2560 x 1600" is true.

A SCSI terminator is a device used in a SCSI (Small Computer System Interface) system to prevent signal reflection at the end of the SCSI bus. It ensures that the electrical signals are properly terminated, preventing data errors and signal degradation. The picture is likely showing a SCSI terminator, which is a small connector or device that is attached to the end of the SCSI bus to terminate the electrical signals.

Windows XP Service Pack 2 requires 1.8GB of hard drive space because service packs are updates and enhancements to the operating system. These updates often include new features, bug fixes, and security improvements. To install these updates, sufficient space is required on the hard drive to accommodate the new files and changes being made to the system. In the case of Windows XP Service Pack 2, it specifically requires 1.8GB of hard drive space to ensure a successful installation and operation of the service pack.

Even after it’s been formatted a hard drive may contain sensitive material so it is best to destroy the it, preferably on a stressful day. Normal clients hard drives can be resused

A Mac computer can read a FAT32 HDD because the FAT32 file system is compatible with both Windows and Mac operating systems. This means that a Mac computer can easily access and read files stored on a FAT32 HDD without any compatibility issues.

Mac's can only read a NTFS formatted disk. This has appeared in the actual exam.

PCI Express is a serial based technology so data can be sent over the bus in two directions at once unlike normal PCI which is parallel.

A hub takes the incoming data packet that comes into a port and copies it out to all the other ports in the hub.

They are both have a max length of 5m. USB 1.0 has a max of 2m.

Turning off SSID may degrade performance and open the network up to passive scanning. Turning off SSID appeared in one users exam.

The statement is true because 8x AGP (Accelerated Graphics Port) has a higher data transfer rate compared to 1x PCIe (Peripheral Component Interconnect Express). AGP was a standard for connecting graphics cards to the motherboard, and 8x AGP had a maximum bandwidth of 2.1 GB/s. On the other hand, PCIe is a newer and faster standard, but 1x PCIe only has a maximum bandwidth of 0.25 GB/s. Therefore, 8x AGP is faster than 1x PCIe.
