PRACTICE IT NOW TO SHARPEN YOUR CONCEPT AND KNOWLEDGE
1. What characteristic of read-only memory (ROM) makes it useful?
- ROM information can be easily updated.
- Data in ROM is non-volatile, that is, it remains there even without electrical power.
- ROM provides very large amounts of inexpensive data storage.
- ROM chips are easily swapped between different brands of computers.
The characteristic of read-only memory (ROM) that makes it useful is its non-volatile nature. ROM retains its data even when the power supply is turned off or interrupted. This means that the information stored in ROM is permanent and cannot be easily modified or erased, providing a reliable and secure storage solution for essential firmware, instructions, and data that need to be preserved in electronic devices.
2. What do you call the programs that are used to find out possible faults and their causes?
- operating system extensions
- cookies
- diagnostic software
- boot diskettes
The programs that are used to find out possible faults and their causes are commonly referred to as "diagnostic programs" or "diagnostic software." These programs are designed to systematically analyze and identify issues within a system or device. They often perform various tests, checks, and measurements to pinpoint potential faults and provide diagnostic information or error codes that can assist in troubleshooting and resolving the problems. Diagnostic programs are widely used in various industries, including computer hardware, automotive, telecommunications, and manufacturing, to ensure efficient fault detection and problem resolution.
3. Which programming languages are classified as low level languages?
- BASIC, COBOL, Fortran
- Prolog
- C, C++
- Assembly languages
Low-level programming languages are those that provide close interaction with the hardware and have minimal abstraction from the computer's architecture. The commonly recognized low-level programming languages are:
1. Assembly Language: Assembly language is a low-level programming language that uses mnemonics to represent specific instructions understood by the computer's processor. It provides direct control over hardware resources and is specific to a particular computer architecture.
2. Machine Language: Machine language is the lowest-level programming language that directly communicates with the computer's hardware. It consists of binary code, represented as 0s and 1s, which the computer's processor can execute directly.
These two languages, Assembly Language and Machine Language, are considered low-level languages because they are closely tied to the hardware and provide fine-grained control over system resources.
4. Which of the following is not anti- viruses’ software?
- NAV
- F-Prot
- Oracle
- McAfee
Oracle is a multinational technology company known for its database management systems, cloud services, and enterprise software solutions
5. Which device is required for the Internet connection?
- Joystick
- Modem
- CD Drive
- NIC Card
Modem: A modem (modulator-demodulator) is a device that connects your computer or network to your Internet service provider (ISP). It modulates and demodulates signals between your computer and the ISP, allowing data to be transmitted over the Internet. The type of modem required depends on the type of Internet connection, such as DSL, cable, fiber optic, or satellite.
6. What does DMA stand for?
- Distinct Memory Access
- Direct Memory Access
- Direct Module Access
- Direct Memory Allocation
DMA stands for Direct Memory Access.Direct Memory Access (DMA) is a feature in computer systems that allows data to be transferred between peripheral devices (such as hard drives, network cards, or sound cards) and the computer's memory without involving the central processing unit (CPU). DMA enables efficient and high-speed data transfers by bypassing the CPU's involvement in the data transfer process.
7. Which of the following is a storage device?
- Tape
- Hard Disk
- Floppy Disk
- All of the above
Certainly! Here are a few examples of storage devices:
1. Hard Disk Drive (HDD): A hard disk drive is a common storage device used in computers and other electronic devices. It utilizes magnetic storage to store and retrieve data.
2. Solid-State Drive (SSD): A solid-state drive is another type of storage device that uses flash memory to store data. SSDs are known for their faster data access speeds and improved reliability compared to traditional hard disk drives.
3. USB Flash Drive: A USB flash drive, also known as a thumb drive or a pen drive, is a portable storage device that connects to a computer through a USB port. It uses flash memory to store data and is commonly used for transferring and storing files.
4. Memory Card: Memory cards, such as Secure Digital (SD) cards or CompactFlash (CF) cards, are small storage devices commonly used in digital cameras, smartphones, and other portable devices to store photos, videos, and other data.
5. Optical Discs: Optical discs, like CDs (Compact Discs), DVDs (Digital Versatile Discs), and Blu-ray discs, are storage media that use optical technology to store and retrieve data. These discs are often used for data backup, software installation, and media storage.
6. Network Attached Storage (NAS): Network Attached Storage is a device or server connected to a network that provides storage and file sharing capabilities to multiple users and devices. It enables centralized data storage and access over a network.
Please let me know if you would like further information or if you have any specific options you would like me to identify as a storage device.
8. When did John Napier develope logarithm?
- 1416
- 1614
- 1641
- 1804
John Napier developed logarithms in the early 17th century. His work on logarithms was published in his book titled "Mirifici Logarithmorum Canonis Descriptio" in 1614. This groundbreaking work introduced the concept of logarithms and their applications, revolutionizing mathematical calculations and trigonometry.
9. A normal CD- ROM usually can store up to _________ _data?
- 680 KB
- 680 Bytes
- 680 MB
- 680 GB
A normal CD-ROM (Compact Disc Read-Only Memory) can usually store up to 700 MB (megabytes) of data. This capacity is based on the standard Red Book format for CDs, which is commonly used for audio CDs and data storage.
10. MIS is designed to provide information needed for effective decision making by?
- Consumers
- Workers
- Foremen
- Managers
MIS plays a crucial role in providing decision-makers with the right information at the right time, enabling them to make informed and effective decisions that contribute to the success of an organization.
