Ad hoc means:
Correct Answer
A. Any device is able to associate with one another
Explanation
Ad hoc refers to a type of network where devices can directly communicate with each other without the need for a central access point or infrastructure. In this context, it means that any device within the network is capable of establishing a connection and communicating with other devices in the same network without relying on a central device or network infrastructure.

The South Bridge on the motherboard includes: (Choose 3)
Correct Answer(s)
C. PCI
D. BIOS
F. IDE
Explanation
The South Bridge on the motherboard includes PCI, BIOS, and IDE. PCI (Peripheral Component Interconnect) is a standard for connecting peripheral devices to the motherboard. BIOS (Basic Input/Output System) is firmware that initializes hardware during the boot process and provides a basic set of instructions for the operating system. IDE (Integrated Drive Electronics) is a standard interface for connecting storage devices like hard drives and optical drives to the motherboard. These three components are essential for the functioning of the motherboard and its connectivity with various devices.
3.
The port number for HTTPS is:
Correct Answer(s)
443
Explanation
The port number for HTTPS is 443. This is the default port used for secure communication over the HTTP protocol. When a user accesses a website using HTTPS, the web browser establishes a secure connection with the server on port 443. This port is specifically designated for secure HTTP traffic, ensuring that data transmitted between the client and the server is encrypted and protected from unauthorized access.

Which two devices are hot-swapable? (Select 2)
Correct Answer(s)
A. USB
C. IEEE 1394
Explanation
USB and IEEE 1394 are the two devices that are hot-swappable. Hot-swappable devices are those that can be connected or disconnected from a computer system while it is still running, without the need for a restart or any other interruption. USB (Universal Serial Bus) and IEEE 1394 (also known as FireWire) are both commonly used for connecting peripherals to a computer, such as external hard drives, cameras, and printers. These devices allow for easy and convenient plug-and-play functionality, making them hot-swappable. HDD (Hard Disk Drive) and RAM (Random Access Memory) are not hot-swappable devices as they require the computer to be powered off before they can be connected or disconnected.
5.
The inverter for a laptop converts DC power to AC power.
Correct Answer
A. True
Explanation
The inverter for a laptop is responsible for converting the direct current (DC) power from the laptop's battery or power adapter into alternating current (AC) power. This is necessary because most electronic devices, including laptops, require AC power to operate. Therefore, the statement "The inverter for a laptop converts DC power to AC power" is true.
6.
What type of connector is this?
Correct Answer
C. VGA
Explanation
This question is asking about the type of connector shown in the image. The correct answer is VGA. VGA stands for Video Graphics Array and it is a type of connector commonly used to transmit video signals from a computer to a monitor or display. VGA connectors have 15 pins arranged in three rows and are typically blue in color. They are widely used in older computer systems and monitors.
7.
Which RAID requires 2 HDDs for disk mirroring?
Correct Answer
B. RAID 1
Explanation
RAID 1 is a mirroring technique that requires 2 HDDs. In this RAID level, data is duplicated on both disks, providing redundancy and increased data reliability. Each disk contains an identical copy of the data, so if one disk fails, the other can continue to function without any data loss. This redundancy makes RAID 1 ideal for applications that require high data availability and fault tolerance.
8.
ECC is primarily found on what type of computer?
Correct Answer
A. Server
Explanation
ECC (Error Correcting Code) is primarily found on servers. Servers are designed to handle large amounts of data and perform complex tasks, making them more prone to errors. ECC memory is used in servers to detect and correct errors in data transmission, ensuring data integrity and reliability. Desktops, laptops, and tablets, on the other hand, typically do not require ECC memory as they are used for less critical tasks and have lower data processing demands.
9.
Windows 7 comes with this default file system:
Correct Answer
D. NTFS
Explanation
Windows 7 comes with the NTFS (New Technology File System) as the default file system. NTFS is a modern and advanced file system that offers improved security, reliability, and performance compared to the older file systems like FAT16 and FAT32. It supports features like file and folder permissions, encryption, compression, and disk quotas. NTFS also provides better support for larger file sizes and disk capacities, making it suitable for modern computer systems.
