Draw a system flowchart illustrating the steps performed by an operating system as it executes the instruction to back up a disk on a single-user computer system.

Answers

Answer 1

The flowchart's pseudo code is as follows:

The command BACKUP user issues through the user interface.UI executes the awakening File Manager instruction.File Manager resolves the address of a backup file that wakes up Device Manager.Device Manager opens the drive access path to back files in the Memory Manager I/O buffer that reads the file (or part of the data).In the I/O buffer, Memory Manager assigns memory to the processor manager.Processor Manager loads the I/O buffer memory file, and File Manager awakens.File Manager determines the document address be copied into the Processor Managers new disc.The Device Managers, Processor Manager copies memory to the I/O buffer.This device manager enables you to open a drive access path where a new disc awakens file manager will be duplicated by the I/O buffer.File Manager decides whether the file is copied completely If yes if you are jumping to point 11, you decide the next area of the file that will be backed up and Device Manager is returning to point 4.File Manager decides if this is the last backup item, if not, it wakes up Manager of Processor Activates Processor Manager for sending interface File N is backed up for a client can jump back to point 3 if affirmative. The Processor Manager activates the user interface to send the user message 'All files have been backed up'.

Explanation:

Suppose you are asked to design a rotating disk where the number of bits per track is constant. You know that the number of bits per track is determined by the circumference of the innermost track, which you can assume is also the circumference of the hole. This, if you make the hole in the center of the disk larger, the number of bits per track increases, but the total number of tracks decreases. If you let r denote the radius of the platter, and x · r the radius of the hole, what value of x maximizes the capacity of the disk?

Juan is a network administrator and must set up a VPN for his company's network. To allow safe communication, he should

select Control Panel, then Network Protocols, then Internet
select the radio button, then change the adapter settings protocol
select the Security tab, then PPTP, and then Allow Protocols
select Set Up a Public Connection, then Disable Protocols

Answers

Answer:

select Control Panel, then Network Protocols, then Internet

Explanation:

Seeing as Juan is a network admin, he has access to the programs of the computer. Being tasked with setting up a VPN, he must go to the control panel, then network protocols (to see the network rules, per say), then the internet tab to finally set up the VPN.

To allow safe communication, Juan must select control panel  then, network protocols, and then  internet. Therefore, option A is correct.

What is VPN ?

You can interact secretly and securely within your corporation using a virtual private network (VPN), which is an extension of a company's intranet over the preexisting structure of either a public or private network.

The i5/OS operating system is utilised by both businesses, and a VPN connection can give them the protection they require to communicate between their respective networks. Compared to using conventional non-switched lines, creating a VPN is more cost-effective.

To allow a safe communication, the network operator should allow the internet protocol to interpret and which can be activated from the control panel. Hence, option A is correct.
