Computers and Technology
1 answer:
Dahasolnce [82]3 years ago
6 0

Answer:

Explanation:

A disk block works by transferring data between the disk and main memory units which are called the blocks, whose size can range drastically from 512 bytes to several thousand.  This data is converted to hardware-level cylinder, surface, and sector number  which makes accessing the data immensely slower than accessing data in the main memory. This time constraint is also the main reason as to why accessing a disk block is so expensive.

Is Using programming libraries is one way of incorporating existing code into new programs true
postnew [5]

Yes, Using programming libraries is one way of incorporating existing code into new programs  is a true statement.

<h3>What function do libraries provide in programming?</h3>

Programming libraries are helpful resources that can speed up the work of a web developer. They offer prewritten, reuseable portions of code so that programmers can easily and quickly create apps. Consider building a program that enables users to enroll in and pay for courses.

Therefore, Using a code library often saves developers from having to create everything from scratch. It can take less time to develop projects and have more reliable software if the catalog of programming resources is kept up well.

You may save more money by using a a0 service, but you will spend more time on creating a contract.
Anon25 [30]

Answer:

contractor management outsourcing

Explanation:

For any recruiter, two things are important. They want to ensure more time, and hence more money. By the time I mean, they want to avoid investing time in something that does not generate revenues. And unfortunately, there exists a bundle of such irrelevant, and yet must-do activities which we need to perform. However, if we opt for contractor management outsourcing to a better management employment relationship, we save a lot of time and earn more as a recruiter. However, we then spend more time creating a contract, as even a single faulty clause can be hard for you to engulf in the future. And that is why it requires more time. However, the good part is, we as a recruiter are happy by the end of the day, as we earn more profit. And it's due to better resource and time management.
