Explanation / Answer
(1)
The command show on the nano editor screen along with the functions are as follows:
Command Function
^G It displays the help text
^X It closes the current file buffer and exit from nano.
^O It writes the current file to the disk.
^J It is used to justify the current paragraph.
^R It is used to insert the file in current file.
^W It is used to search for a string or a regular expression.
^Y It is used to move to the previous screen.
^V It is used to move to next screen
^K It is used to cut the current line.
^U It is used to uncut from the buffer.
^C It displays the position of the cursor.

The 4 parts that magnetic hard drives have are:
Platters: It is used to store the data permanently. The data is stored on the platters in tracks, sectors and cylinders
Spindle: It helps to position the platters and perform rotation. The more the number of rotations, the faster is the speed of the data that can be written to and read from the drive.
Read Write Arm: It reads the data on the platter by movement of the read head and writes the new data on the platter through the movement of the write head.
Actuator: It causes the arm to move.

personal computers today is IDE/PATA.
(4)
The most popular current data connectors for magnetic hard drives found in
personal computers today is SATA

The 5 Server parts that are usually not found in laptops are as follows:
(7)
a – The number of bits that are transferred, at the time, in parallel ports are 8 bits or 1 byte.
b – The number of bits that are transferred, at the time, in serial ports is 1 bit.

The most common speeds for secondary storage are as follows:
(9)
The main differences are as follows:
a – Hubs: This device is the least expensive and least complicated. The information sent to the hub is sent to every device in the network.
b – Switches: It is more effective as it filters and forwards the packets between LAN segments.
c – Routers: It is the device which forwards the data packets along networks. It is the smartest and most complicated. It is connected to at least two networks (LANs or WANs)
