- A.
Cache
- B.
Buffer
- C.
Interface
- D.
Interrupt
Correct Answer
D. InterruptExplanation
An interrupt is defined as an asynchronous signal from a computer hardware device indicating the need for attention from a central processing unit (CPU) or a synchronous event. When an interrupt occurs, it temporarily suspends the normal execution of the CPU and transfers control to a specific interrupt handler routine. This allows the CPU to respond to the event or request from the hardware device in a timely manner, ensuring efficient communication and coordination between the CPU and the device.Rate this question:

Correct Answer
B. ParityExplanation
Parity is considered as a technique or method of checking data integrity. It involves adding an extra bit to a binary code to ensure that the total number of 1s in the code is always even or odd. This allows for the detection of errors that may occur during data transmission or storage. By comparing the parity bit with the received data, any discrepancies can be identified, indicating a potential error in the data.Rate this question:

(202) Which is a very simple example of an error detecting code?
- A.
Interrupt
- B.
Parity bit
- C.

- D.
Data integrity
Correct Answer
B. Parity bitExplanation
A parity bit is a very simple example of an error detecting code. It is a single bit added to a binary code to detect errors during transmission. The parity bit is set to either 0 or 1, depending on whether the number of 1s in the code is even or odd. During transmission, the parity bit is recalculated at the receiving end, and if it doesn't match the expected value, an error is detected. This method is simple and efficient in detecting single-bit errors, making it a commonly used error detection technique.Rate this question:

- D.
Internet small computer system interface (iSCSI)
Correct Answer
A. Fibre channelExplanation
The correct answer is Fibre channel. Fibre channel is the preferred connection type for storage area networks (SAN) because it provides high-speed and reliable data transfer between servers and storage devices. It offers high bandwidth, low latency, and the ability to connect multiple devices in a network. Fibre channel also supports long distances and can be used for both block-level and file-level storage. It is commonly used in enterprise environments where high-performance storage and data access are critical.Rate this question:

- C.
Small computer system interface (SCSI)
- D.
Redundant array of independent disks (RAID)
Correct Answer
D. Redundant array of independent disks (RAID)Explanation
RAID stands for Redundant Array of Independent Disks. It is a storage technology that combines multiple physical hard drives into a single logical unit. RAID provides data storage reliability by using redundancy, which means that data is duplicated and stored across multiple drives. This redundancy ensures that if one drive fails, the data can still be accessed from the remaining drives. RAID is commonly used in enterprise environments where data reliability and availability are critical.Rate this question:

(204) The hard drives in a redundant array of independent disks (RAID) array are presented to the server as __________
- A.
One single hard drive
- B.
A collection of hard drives
- C.
A single RAID array
- D.
A remote storage device
Correct Answer
A. One single hard driveExplanation
The hard drives in a RAID array are presented to the server as one single hard drive. In a RAID array, multiple physical hard drives are combined and managed as a single logical unit. This allows for increased performance, fault tolerance, and data redundancy. The server sees the RAID array as a single hard drive, abstracting the complexity of multiple drives from the operating system and applications. This simplifies data management and allows for easier implementation of RAID technology.Rate this question:

- D.
Peripheral component interconnect express (PCIe)
Correct Answer
A. Small computer system interface (SCSI)Explanation
SCSI (Small Computer System Interface) is often used in redundant array of independent disks (RAID) arrays that can be daisy chained. SCSI is a high-performance interface that allows multiple devices to be connected to a single host adapter. It supports multiple devices in a chain, allowing for easy expansion and scalability in RAID arrays. SCSI also provides faster data transfer rates and better performance compared to other technologies like SATA or PCIe, making it a preferred choice for RAID configurations.Rate this question:

- B.
Extensible Markup Language (XML)
- C.
HyperText Markup Language (HTML)
- D.
Dynamic HTML (DHTML)
Correct Answer
C. HyperText Markup Language (HTML)Explanation
HTML is the correct answer because it is a set of markup symbols or codes that are used to structure the content of a web page and define its layout. HTML tags are inserted into the file to indicate how the content should be displayed on a web browser page. SGML and XML are also markup languages, but they are not specifically designed for web browser display. DHTML is a combination of HTML, CSS, and JavaScript that allows for dynamic and interactive web content, but it is not a set of markup symbols or codes inserted in a file.Rate this question:

Correct Answer
B. Common Gateway Inferface (CGI)Explanation
A standard Web application used to pass a Web user's request to a server's application program and to exchange data back to the user is called a Common Gateway Interface (CGI). CGI is a protocol that allows communication between a web server and a server-side program. It enables the web server to pass user requests to the server-side program, which then processes the request and sends the response back to the web server for display to the user. This allows dynamic content generation and interaction with databases or other resources on the server.Rate this question:

Data Encryption Standard (DES)
- D.
Transport Layer Security (TLS)
Correct Answer
A. Secure Socket Layer (SSL)Explanation
Secure Socket Layer (SSL) is commonly used for managing the security of a message transmission on the Internet. SSL provides encryption and authentication mechanisms to ensure secure communication between a client and a server. It establishes a secure connection by encrypting the data transmitted between the two parties, preventing unauthorized access and protecting the integrity of the message. SSL is widely used for secure online transactions, such as e-commerce websites, online banking, and email services. It has been widely replaced by Transport Layer Security (TLS), but SSL is still commonly referred to when discussing secure communication protocols on the Internet.Rate this question:

- C.
Recursive query
- D.
Non-recursive query
Correct Answer
D. Non-recursive queryExplanation
A non-recursive query is made by one name server to another name server. In a non-recursive query, the name server being queried does not provide the complete answer to the query, but instead refers the querying server to another name server that may have the answer. This process continues until the querying server receives a complete answer or reaches a timeout. Non-recursive queries are commonly used in DNS resolution to efficiently distribute the workload among multiple name servers.Rate this question:
