Answer:
Check the printing properties or print test page.
Explanation:
In a situation whereby an inkjet printer’s output appears to have missing elements. The first thing a technician should try if the ink cartridge appears to be full to "Check the printing properties."
This helps to serve as a maintenance technique or solve the ink cartridge problems.
Depending on the windows or PC's Operating System. To check the printer's properties on Windows 7, a user will have to click on the “Start” button > Control panel > Devices and Printers. Followed by right-clicking the printer icon and open up “Printer Properties” and click “Print Test Page”
Answer:
1. SSH/Telnet.
2. SMTP.
3. DNS.
4. DHCP.
5. HTTPS/SSL.
6. FTP
Explanation:
1. Provides connections to computers over a TCP/IP network: the standard protocol used for this is SSH/Telnet, through port number 22 and 23 respectively.
SSH is acronym for secure shell.
2. Sends e-mail over a TCP/IP network: SMTP using port number 25.
SMTP is an acronym for Simple Mail Transfer Protocol and it uses the standard port number of 25 to provide clients with requested services.
3. Translates URLs to IP address: DNS using port number 53.
A Domain Name System (DNS) can be defined as a naming database in which internet domain names (website URLs) are stored and translated into their respective internet protocol (IP) address. This simply means that, DNS is used to connect uniform resource locator (URL) or web address with their internet protocol (IP) address.
4. Automates assignment of IP address on a network: DHCP using port number 67.
Dynamic Host Configuration Protocol (DHCP) is a standard protocol that assigns IP address to users automatically from the DHCP server.
5. Securely transports web pages over a TCP/IP network: HTTPS/SSL using port number 443.
HTTPS is acronym for Hypertext Transfer Protocol Secure while SSL is acronym for Secure Sockets Layer (SSL).
6. Transports files over a TCP/IP network: FTP using port number 20 or 21.
FTP is an acronym for file transfer protocol.

Answer:
Only Technician B is right
Explanation:
Technician A is wrong because the brakes will grab and cause the wheel to lock up and slide only if the coefficient of friction is too high. If the coefficient of friction is too low, excessive pressure on the brake pedal will be required to stop the vehicle.
Technician B is right the materials in contact is a factor that influences the coefficient of friction. For example, when ice slides on steel, the two materials slide past each other easily, this means that icehas a low coefficient of friction. On the other hand, rubber on pavement has a high coefficient of friction as the materials do not slide past each other easily.
Therefore, only Technician B is right.
