What is dual processing?

User Avatar

Asked by Wiki User

Dual processing refers to the idea that our brains can process information in two different ways simultaneously: one being automatic and unconscious, and the other being deliberate and conscious. This concept helps explain how we can perform both routine tasks and complex cognitive activities at the same time.

Describe the main types of primary and secondary storage?

User Avatar

Asked by Wiki User

Primary storage includes Random access memory (RAM) which is fast and volatile. Secondary storage consists of devices like hard disk drives (HDD) and solid-state drives (SSD) which are slower but non-volatile, allowing data to be stored for longer periods even when the power is turned off.

What is the difference between short term memory and working memory?

User Avatar

Asked by Wiki User

Short term memory refers to the temporary storage of information for a brief period, usually around 15-30 seconds. Working memory, on the other hand, involves actively processing and manipulating this information to perform tasks such as problem-solving or decision-making. Working memory is like the "workspace" where short term memory is utilized for cognitive tasks.

Definition of primary memory?

User Avatar

Asked by Wiki User

Primary memory, also known as main memory or internal memory, refers to the storage area in a computer where data and instructions are stored for quick access by the CPU. It includes Random Access Memory (RAM) and cache memory, which are volatile and temporary storage locations used during the operation of the computer. Data stored in primary memory is lost when the computer is powered off.

Distinguish between in primary and secondary memory?

User Avatar

Asked by Wiki User

Primary memory, also known as main memory, refers to the computer's directly accessible memory that includes RAM and cache memory. It is volatile and stores data that is actively used by the computer. Secondary memory, on the other hand, is non-volatile memory that includes storage devices like hard drives and SSDs. Data stored in secondary memory is retained even when the computer is turned off.

WordStar is often considered the first widely used word processor for microcomputers. It was released in the late 1970s and became popular among users of early personal computers.

Is there any difference between micro-controller and PIC?

User Avatar

Asked by Wiki User

A microcontroller is a general term for a small computer contained on a single integrated circuit, while PIC (Peripheral Interface Controller) is a specific type of microcontroller developed by Microchip Technology. So, all PICs are microcontrollers, but not all microcontrollers are PICs.

Highest priority interrupt in micro processor?

User Avatar

Asked by Wiki User

The highest priority interrupt in a microprocessor is usually the reset interrupt. When a reset occurs, the microprocessor is forced to stop its current operations and begin executing the reset routine. This is critical for initializing the processor and setting it to a known state before starting normal operations.

Left bound report how would the left margin be set?

User Avatar

Asked by Wiki User

In a left-bound report, the left margin is set to align the text content on the left side of the page. This margin is typically adjusted using the page layout settings in the document formatting software or through CSS properties if working on a web-based report. A common left margin measurement is around 1 inch or 2.54 centimeters to ensure a professional and organized layout.

What is the top margin of an unbound report?

User Avatar

Asked by Wiki User

The top margin of an unbound report is typically around 1 inch (2.54 cm) to allow for headers and binding space if needed. However, this margin size can vary depending on the specific requirements of the report or the preferences of the person creating it.

What are the advantages and disadvantages of plotter printer?

User Avatar

Asked by Wiki User

Advantages of a plotter printer include the ability to produce high-quality, large-format prints with precise detail. They are ideal for technical drawings, architectural designs, and engineering diagrams. However, plotter printers are typically more expensive than traditional printers and may take longer to print due to their intricate, detailed printing process.

Your system problem is ntldr file is missing in every system restrat First time you are reinstall the OS is booting what can you do?

User Avatar

Asked by Wiki User

If the NTLDR file is missing on every system restart, you can try booting from the Windows installation disk or a USB drive and use the repair options to fix the NTLDR file. Alternatively, you can try using a bootable recovery tool to repair the missing NTLDR file. If these options don't work, you may need to perform a clean installation of the operating system.

How important is computer hardware to the computer system?

User Avatar

Asked by Wiki User

That depends on what you plan on doing on the computer system, if you plan on running taxing programs, like games or graphic modeling programs, then computer hardware is extremely important, on the other hand if you are only intrested in surfing the internet and writing word documents then computer hardware is fairly unimportant.

Dual power supply?

User Avatar

Asked by Wiki User

A dual power supply refers to a system that provides two separate power sources to a device or circuit. This setup offers redundancy and can help improve reliability in case one power source fails. It is commonly used in critical systems where uninterrupted power supply is necessary.

What is the difference between artificial neural network and hidden Markov model methods?

User Avatar

Asked by Wiki User

Artificial neural network is a machine learning model that processes data in a non-linear way, while hidden Markov model is a statistical model that deals with sequential data and uses probabilities to model transitions between states. In neural networks, the focus is on learning the underlying patterns within the data, while in hidden Markov models, the emphasis is on estimating the probabilities of transitioning between different states.

How are computers used in libraries?

User Avatar

Asked by Wiki User

Computers in libraries are most often used to gain access to the library's book database, a more modern version of previous library cards. This interface usually allows searching the database for a genre of books, and the ability to check whether a book is available in the building. Some libraries allow internet access from their computers for online research and other related functions.

How do you fix missing or corrupt boot sector?

What does Non-EPP mean?

User Avatar

Asked by Wiki User

Non-EPP stands for "Non-Extended Payment Protection." It typically refers to payment protection services that do not provide extended coverage beyond the usual warranty or guarantee period. EPP, on the other hand, usually offers additional protection beyond the standard coverage.

What happens when you overclock your system?

User Avatar

Asked by Wiki User

When you overclock your system, you increase the clock rate of your CPU or other hardware components beyond their default settings to achieve higher performance. This can lead to improved speed and responsiveness in tasks that rely heavily on processing power. However, overclocking can also generate more heat and potentially reduce the lifespan of your hardware if not properly managed with adequate cooling solutions.
