Which one is a storage units?
-
Keyboard
-
RAM
-
CPU
-
Monitor
Correct Answer
A. RAMExplanation
RAM stands for Random Access Memory and it is a type of storage unit in a computer. It is used to temporarily store data that is actively being used by the computer's operating system and applications. Unlike the hard drive, which is a permanent storage unit, RAM is volatile and loses its data when the computer is turned off. Therefore, RAM is responsible for providing fast and temporary storage for data that needs to be quickly accessed by the computer's processor.Rate this question:

If a device have CPU,RAM,ROM,HDD and OS , this device is a computer.
-
True
-
False
Correct Answer
A. TrueExplanation
The given statement suggests that if a device has a CPU, RAM, ROM, HDD, and an operating system (OS), it can be classified as a computer. This is true because these components are essential for a device to perform computing tasks. The CPU is responsible for executing instructions, RAM provides temporary storage for data, ROM stores firmware and permanent instructions, HDD allows for long-term storage of data, and the OS manages the device's resources and provides a user interface. Therefore, having all these components makes the device capable of functioning as a computer.Rate this question:

-
Menu Driven Interface ( MDI)
-
Form Based Interface ( FBI)
-
Natural Language Interface ( NLI)
Correct Answer
A. Command Line Interface ( CLI)Explanation
The correct answer is Command Line Interface (CLI). A command line interface allows users to interact with the operating system by typing commands into a terminal or console. It is a text-based interface that provides more control and flexibility compared to graphical user interfaces. Users can execute commands, navigate through directories, manage files, and perform various tasks using specific commands and syntax. CLI is commonly used by advanced users, system administrators, and developers who prefer the efficiency and power of a text-based interface.Rate this question:

HDD and memory stick are temporary storage devices.
-
True
-
False
Correct Answer
A. FalseExplanation
The statement is false because HDD (Hard Disk Drive) is a permanent storage device, while a memory stick (USB flash drive) is a removable storage device. Both devices can store data, but HDD retains the data even when the power is turned off, making it a non-volatile storage device. On the other hand, a memory stick is a volatile storage device, meaning it requires power to retain the data.Rate this question:

If firmware in ROM is not know added new device in system, need to install or write software program.This software program is called
-
USB
-
Device Driver
-
Mermory Card
-
ROM-firmware
Correct Answer
A. Device DriverExplanation
When a new device is added to a system and the firmware in ROM does not recognize it, a software program needs to be installed or written to enable communication between the device and the system. This software program is called a device driver. It acts as a bridge between the hardware device and the operating system, allowing them to communicate and work together seamlessly.Rate this question:

What operating system is used for DHCP,Mail,File Service etc?
-
Desktop Operating System
-
Server Operating System
-
Network Operating System
-
Network Security Operation System
Correct Answer
A. Server Operating SystemExplanation
The correct answer is Server Operating System. DHCP, Mail, File Service, etc. are typically provided by server software, which requires a server operating system to run. A server operating system is specifically designed to handle the demands of serving multiple clients and managing network resources. It provides features like centralized administration, security, scalability, and performance optimization, making it suitable for hosting services like DHCP, mail servers, and file servers.Rate this question:

---------------- is the only RAID type without fault tolerance.
Correct Answer
RAID 0, RAID0,Raid 0Explanation
RAID 0, also known as RAID0 or Raid 0, is the only RAID type without fault tolerance. In RAID 0, data is striped across multiple drives, which improves performance by allowing simultaneous read and write operations. However, since there is no redundancy or mirroring of data, if one drive fails, the entire array becomes inaccessible, resulting in data loss. Therefore, RAID 0 does not provide any fault tolerance or data protection.Rate this question:

What operating system is used for IP Camera, Setup Box, TV , Phones etc?
-
Network OS
-
Network Security OS
-
Embedded OS
-
Desktop OS
Correct Answer
A. Embedded OSExplanation
Embedded OS is the correct answer because IP cameras, setup boxes, TVs, and phones are all examples of devices that require a specialized operating system that is specifically designed to run on low-power, resource-constrained hardware. Embedded operating systems are lightweight, efficient, and optimized for the specific tasks and functions of these devices. They are typically built to provide real-time performance, stability, and security, making them ideal for use in embedded systems like IP cameras, setup boxes, TVs, and phones.Rate this question:

Open Source is all source code can change and edit if needed.Window OS is an example of open source.
-
True
-
False
Correct Answer
A. FalseExplanation
The given answer is false because Window OS is not an example of open source. Open source refers to source code that is freely available and can be modified and distributed by anyone. However, Windows OS is a proprietary operating system developed by Microsoft, and its source code is not freely available for modification.Rate this question:

Firmware is a program written in
-
RAM chip set
-
CPU
-
ROM chip set
-
HDD and Flash Memory
Correct Answer
A. ROM chip setExplanation
Firmware is a program that is stored in ROM (Read-Only Memory) chip set. ROM is a type of memory that retains data even when the power is turned off, making it ideal for storing permanent software instructions like firmware. Unlike RAM (Random Access Memory) which is volatile and loses data when power is lost, ROM is non-volatile and provides a stable storage medium for firmware. Therefore, the correct answer is ROM chip set.Rate this question:

Which RAID is good performance ( access read/write) , at least same data HDD 4 nos and add new HDD must be even number?
-
RAID 1
-
RAID 5
-
RAID 6
-
RAID (1+0)
Correct Answer
A. RAID (1+0)Explanation
RAID (1+0) is the correct answer because it provides good performance for both read and write operations. In RAID (1+0), also known as RAID 10, data is striped across multiple mirrored pairs of drives. This allows for simultaneous read and write operations, improving performance. Additionally, RAID (1+0) requires an even number of drives, which ensures that there is an equal distribution of data across the drives. This further enhances performance as data can be accessed from multiple drives simultaneously.Rate this question:

Program in ROM normally cannot not be write but which of the following can delete,read and write program in ROM by normal way?
-
PROM-(programmable ROM)
-
EEPROM-Electrically EPROM
-
EPROM- Erasable Programmable ROM
-
Flash Memory
Correct Answer
A. EPROM- Erasable Programmable ROMExplanation
EPROM (Erasable Programmable ROM) is the correct answer because it can be erased and reprogrammed multiple times. Unlike other types of ROM, EPROM can be erased by exposing it to ultraviolet light, which allows it to be reprogrammed with new data. This makes EPROM a versatile and flexible option for storing and updating programs. PROM (programmable ROM) can only be programmed once and cannot be erased or reprogrammed. EEPROM (Electrically EPROM) can be erased and reprogrammed electrically, but it requires a higher voltage compared to EPROM. Flash memory is a type of non-volatile memory that can be electrically erased and reprogrammed, making it suitable for use in devices like USB drives and solid-state drives.Rate this question:
