Difference between direct sequential file and index sequential file?
Explain the difference between sequential and direct file access.A. Sequential access to data is used when the data has to be read from the start, in sequence. It is the normal method of access for magnetic tape. Direct access is used when it is possible to jump directly to a file or data item without reading through all the items stored before it. This is the normal method used for hard disks.
If you take out the battery in a capacitor before inserting a dielectric will there still be charge on the dielectric?
The charge in a capacitor is between the plates. The dielectric is only an insulator that allows the plates to be very close without touching and discharging the charge. There is no battery in a capacitor.
What is an invention that we can't live without?
People were living before each invention and continued to live after, so there is no invention that we CANNOT live without.
Can you save java source file without saving?
So you want to save a file, without saving it... You have some stuff to learn before you tackle java.
When there is a break on the circuit what is the reading?
The typical answer is current is zero when there is a break in the circuit. It depends on the complexity of the circuit, there may be other paths for the current to flow, such that if there is a break in one part of the circuit, the rest of the circuit still has current flow (but a different value than designed). If you are reading voltage, and there is a break then that will change, also depending on the complexity. If it is a single loop, and you're reading voltage before the break, your voltmeter will read the same voltage as the voltage source, since there is no current flowing between any resistors between the meter and the source. If you're reading voltage after the break then the meter will read zero (0) volts.
Which type of data access allows access to any piece of data in the file without reading the data that comes before it?
Direct access. AS
Which software type allows users to have access to it for a limited time before it expires?
esrgergs
Serial and direct access?
direct access allows you to access the needed record directly with serial access u have to go through all the others before arriving to the desired one
How can I find a bike rack that allows me to easily open my trunk?
You can find a bike rack that allows easy access to your trunk by looking for models with a tilting feature or swing-away design. These types of racks allow you to access your trunk without having to remove the bikes or rack. Be sure to check the specifications and compatibility with your vehicle before making a purchase.
Which is not a good reason to employ pre reading techniques before digging into a assignment?
A bad reason to not employ pre-reading techniques before an assignment would be assuming that you already know everything about the topic. Pre-reading allows you to gain an overview of the material, identify key points, and better understand the structure of the content.
Why must the magnetic stirrer be stopped each time before reading the pH?
The magnetic stirrer must be stopped before reading the pH because the movement of the stir bar can cause fluctuations in the solution that could affect the accuracy of the pH measurement. Stopping the stirrer allows the solution to come to rest, giving a more stable reading of the pH.
How do you match these reading techniques with when technique is used A Surveying B Paraphrasing C Summarizing 1 While reading 2 Before reading 3 After reading?
Survey . . . Before reading Paraphrasing . . . While reading Summarizing . . . After reading
What is blank reading for titration of iodine value?
Blank reading is the initial reading taken before adding the sample in the titration of iodine value. It represents the baseline value of the titrant solution without the presence of the sample. This reading is used to ensure accuracy in calculating the iodine value of the sample by subtracting it from the final reading after titration.
Which type of access refers to locating a particular data item immediately without having to move consecutively through items stord in front of desired data item or file?
Direct access allows data to be retrieved instantly without having to sequentially search through other items stored before the desired data item. This method enables quick and efficient retrieval of specific data items from a storage device.
When digital caliper jaws are closed the reading without a part must read?
When the digital caliper jaws are closed without a part, the reading should be zero. This ensures that accurate measurements start from a baseline of zero before taking any measurements. If the reading is not zero when the jaws are closed, it may indicate a need for calibration or adjustment.
What is a helpful pre reading question to ask yourself before reading a business document?
why am i reading this?
Before you start reading you should?
figure out your purpose for reading.
