Answer:
batch sequence check.
Explanation:
A batch sequence check can be defined as a strategic and systematic control plan which typically involves the process of inputting a range of numbers comprising a batch and then inputting each serially numbered document.
The steps for checking an event data within a batch using a batch sequence check include the following;
I. You'll enter a range of serial numbers of the document in a batch.
II. You'll enter each serially pre-numbered document one after the other.
III. The input documents are sorted by a computer into a serial (numerical) order, match the sequence number range against the input documents, and then reports any part of the document that is missing, a duplicate and out of range.
Answer:
NAT provides some security but allows a firm to have more internal IP addresses
Explanation:
NAT ( network address translation) this is a process where a network system usually a firewall assigns a public IP address to an internal computer used in a private network. it limits the number of public IP address a company operating a private network for its computer can have and this is very economical also limits the exposure of the company's private network of computers. the computers can access information within the private network using multiple IP addresses but it is safer to access external information using one public IP address
