Correct Answer
D. A broad set of instructions, resulting in fewer steps per operation.Explanation
CISC stands for Complex Instruction Set Computer. This architecture uses a broad set of instructions, resulting in fewer steps per operation. Unlike RISC (Reduced Instruction Set Computer), CISC processors are designed to handle complex instructions that can perform multiple tasks in a single operation. This approach allows for more efficient execution of tasks, as fewer instructions are needed to accomplish a particular operation. However, CISC processors may sacrifice some speed for the flexibility and versatility provided by the larger instruction set.Rate this question:

Information is written to this particular ROM chip after it is manufactured. It can be erased with UV light
- A.
ROM
- B.
EPROM
- C.
EEPROM
- D.
WANTTOGOTOPROM
Correct Answer
B. EPROMExplanation
EPROM stands for Erasable Programmable Read-Only Memory. It is a type of ROM chip that can be programmed and erased multiple times using ultraviolet (UV) light. Unlike regular ROM, which is permanently programmed during manufacturing, EPROM can be reprogrammed by exposing the chip to UV light, which erases the existing data. This makes EPROM a flexible and reusable memory chip, suitable for applications where the stored information needs to be updated or changed.Rate this question:

In regards to Error Checking which method is the most thorough.
- A.
Nonparity
- B.
Parity
- C.
Error Correction Code (ECC)
Correct Answer
C. Error Correction Code (ECC)Explanation
Error Correction Code (ECC) is the most thorough method for error checking because it not only detects errors but also corrects them. Unlike Nonparity and Parity methods that can only detect errors, ECC can identify and fix errors in data transmission. ECC achieves this by adding extra bits to the data, which allows it to reconstruct the original information even if errors occur during transmission. This makes ECC more reliable and effective in ensuring data integrity.Rate this question:

What is used to optimize disk space on a computer by enabling faster access to data.
- A.
Fdisk
- B.
Disk cleanup
- C.
Disk Management
- D.
Scandisk
- E.
Defrag
Correct Answer
E. DefragExplanation
Defrag, short for defragmentation, is a process used to optimize disk space on a computer by rearranging fragmented data on the hard drive. Over time, as files are added, deleted, and modified, they can become fragmented, meaning they are stored in non-contiguous clusters on the disk. This can slow down data access times. Defragging reorganizes the fragmented files, placing them in contiguous clusters, which enables faster access to data and improves overall system performance. Therefore, defrag is the correct answer for optimizing disk space and enhancing data access speed.Rate this question:

Which is the most secure type of file system?

NTFS (New Technology File System) is considered the most secure type of file system due to its advanced security features. It supports file and folder level permissions, encryption, and access control lists, providing better control over data access and protection against unauthorized access. NTFS also has built-in features for error detection and recovery, ensuring data integrity. In contrast, FAT32 (File Allocation Table) lacks these security features, making it less secure. Therefore, NTFS is the preferred choice when security is a top priority.Rate this question:
