question
Moore's Law refers to the
answer
number of transistors inside a CPU chip.
Explanation: observation that the number of transistors in a dense integrated circuit doubles approximately every two years. The observation is named after Gordon Moore, the co-founder of Fairchild Semiconductor and Intel, whose 1965 paper described a doubling every year in the number of components per integrated circuit, and projected this rate of growth would continue for at least another decade. In 1975, Moore revised his estimate to a doubling every two years.This observation has held true for over 50 years and has driven the rapid pace of innovation in the semiconductor industry. Moore's Law is often used as a measure of the progress of the industry, and has been used to predict the future of semiconductor technology.The rate of improvement described by Moore's Law is not consistent across all measures of semiconductor progress. For example, while the number of transistors on a chip has continued to increase at a rapid pace, the speed of those transistors has not increased at the same rate. In fact, the speed of transistors has actually slowed down in recent years, due to the physical limitations of silicon.However, Moore's Law is still considered a valuable measure of progress in the semiconductor industry, and is used to predict future trends. For example, it is often used to estimate the amount of time it will take for a new technology to become economically viable.
question
When the CPU actually performs the work described in the commands during a machine cycle, this stage is known as
answer
Execute
Explanation: the execution stageThe execution stage is when the CPU actually performs the work described in the commands during a machine cycle. This is when the CPU reads the instructions from memory and executes them. The CPU will fetch the next instruction from memory, decode it, and then execute it.
question
Computers are designed with
answer
both volatile and nonvolatile memory.
Explanation: a specific purpose in mindComputers are designed to perform a wide range of tasks, from simple data processing to complex tasks such as artificial intelligence and machine learning. However, each type of computer is designed with a specific purpose in mind. For example, a supercomputer is designed for complex tasks such as weather forecasting and nuclear research, while a personal computer is designed for more general tasks such as word processing and playing video games.
question
A good way to assess your CPU usage is to
answer
check the Performance tab of the Task Manager.
Explanation: monitor your performance when you areThere are a few things you can do to assess your CPU usage and performance. One is to monitor your performance when you are running different programs. If you notice that your CPU usage is consistently high when you are running certain programs, then that is likely a sign that you need to upgrade your CPU. Another way to assess your CPU usage is to keep an eye on your system resources monitor. This will show you how much of your CPU is being used at any given time. If you notice that your CPU usage is consistently high, even when you are not running any programs, then that is an indication that you may have a virus or other malware on your system.
question
_______ is a set of strategies for using more than one drive in a system.
answer
RAID
Explanation: RAID is a set of strategies for using more than one drive in a system. The most common types of RAID are 0, 1, and 5. RAID 0 is also known as disk striping and is the least common type of RAID. It offers no redundancy, so if one drive fails, all data on the array is lost. RAID 1 is also known as disk mirroring and offers redundancy by writing the same data to two drives. If one drive fails, the other drive can be used to retrieve the data. RAID 5 is also known as disk striping with parity and offers redundancy by writing data and parity information to three or more drives. If one drive fails, the data can be reconstructed from the other drives.
question
GDDR5 and GDDR3 are types of
answer
video memory.
Explanation: SDRAM (Synchronous Dynamic Random-Access Memory). SDRAM is a type of DRAM (Dynamic Random-Access Memory) that is synchronized with the system bus. GDDR5 is the most recent type of SDRAM, and is used in high-end graphics cards. GDDR3 is an older type of SDRAM, and is used in lower-end graphics cards.
question
If you want to use your computer for recording your band, you would benefit most from a(n)
answer
MIDI interface.
Explanation: If you want to use your computer for recording your band, you would benefit most from a digital audio interface. This is because a digital audio interface will allow you to connect your instruments and microphones directly to your computer, and it will also provide you with better sound quality than other types of interfaces.
question
Before donating your Windows computer, you should perform a Windows
answer
Reset.
Explanation: resetWhen you reset your Windows computer, it will restore the operating system to its factory default settings. This will remove any personal files, settings, and applications that you have installed. You should only reset your Windows computer if you are planning to donate it or sell it.
question
The fastest memory in a computer is
answer
cache.
Explanation: The fastest memory in a computer is the Random Access Memory (RAM). This is the memory that is used by the computer to store information that is currently being used. The RAM is a type of volatile memory, which means that it will lose its contents when the power is turned off.
question
Windows creates "restore points" so that you can
answer
return your system to the way it was before you installed new software.
question
Desktop systems are invariably a better value than lighter, more mobile computers.
answer
TRUE
question
SSD drives are preferable to conventional hard drives because they transfer data more quickly.
answer
TRUE
Explanation: SSD drives are faster than conventional hard drives for a number of reasons. First, SSDs have no moving parts, so they can access data much faster than a hard drive can. Second, SSDs can read and write data in parallel, while a hard drive can only do one at a time. Finally, SSDs use a technology called NAND flash, which is much faster than the spinning disks used in hard drives.
question
In Windows, if you experience unreliable behavior, try a System Restore before doing a Windows Refresh.
answer
TRUE
Explanation: If you experience unreliable behavior in Windows, it is recommended that you try a System Restore before doing a Windows Refresh. System Restore can help resolve issues by reverting your computer to a previous state without affecting your personal files. If System Restore does not resolve the issue, then you can try a Windows Refresh, which will reinstall Windows and keep your personal files intact.
question
There is no limit to how much RAM you can add to modern computers.
answer
FALSE
Explanation: Adding RAM to a computer is a relatively simple and inexpensive way to improve its performance. The more RAM a computer has, the more information it can store in its memory, which allows the computer to work with more data at the same time. There is no limit to the amount of RAM that a computer can use, and there are no negative consequences to adding too much RAM. In fact, the only downside to adding RAM is that it can be expensive, and it is not always necessary. If a computer is already performing well, adding more RAM may not provide any noticeable benefit.
question
Moore's Law describes the pace at which central processing units (CPUs) improve.
answer
TRUE
Explanation: The law is named after Gordon Moore, the co-founder of Fairchild Semiconductor and Intel.The law states that the number of transistors on a CPU will double approximately every two years. This trend has held true since the early days of the semiconductor industry and is expected to continue into the foreseeable future.The implications of Moore's Law are far-reaching. The rapid pace of improvement in CPU performance has allowed for the development of powerful new computing technologies that have transformed the way we live and work. The law has also had a major impact on the global economy, as the semiconductor industry has become one of the most important and valuable sectors in the world.
