Name two advantages of an impact printer.
- A.
Has carbon copy printing capability
- B.
Quiet
- C.
Fast printing
- D.
Uses inexpensive consumables
- E.
Hi-resolution graphics
Correct Answer(s)
A. Has carbon copy printing capability
D. Uses inexpensive consumablesExplanation
The two advantages of an impact printer are its ability to have carbon copy printing capability and its use of inexpensive consumables. With carbon copy printing, the printer can create multiple copies of the same document simultaneously, which is useful for creating duplicates or keeping records. Additionally, the use of inexpensive consumables means that the printer is cost-effective to operate, as the consumables required for printing, such as ink ribbons, are affordable and easily replaceable.Rate this question:

Which type of printer melts ink and spays it through a nozzle.
- A.
Thermal
- B.
Solid ink
- C.
Ink jet
- D.
Impact
Correct Answer
B. Solid inkExplanation
Solid ink printers melt solid ink sticks and spray the liquefied ink through a nozzle onto the paper. This type of printer uses a heating element to melt the ink, which then passes through the nozzle and onto the paper in a controlled manner. Solid ink technology offers vibrant colors and is known for its high-quality print output. It is commonly used in professional printing applications where color accuracy and print durability are important factors.Rate this question:

- A.
Full duplex
- B.
Multiplex
- C.
Simplex
- D.
Half duplex
Correct Answer
A. Full duplexExplanation
Full duplex is the correct answer because it refers to a method of data transfer where information can be sent and received simultaneously. In full duplex communication, both parties can transmit and receive data at the same time, allowing for faster and more efficient data transfer compared to other methods such as half duplex or simplex.Rate this question:

The quality of printing is measured in .
Correct Answer
dpi
dots per inchExplanation
The quality of printing is measured in dpi, which stands for dots per inch. DPI refers to the number of dots that can be placed within a one-inch space. A higher DPI means more dots and therefore a greater level of detail and clarity in the printed image. This measurement is commonly used in the printing industry to determine the resolution and sharpness of printed materials.Rate this question:

How many pairs of wires are used in an RJ-45 connector
- A.
2
- B.
4
- C.
3
- D.
5
- E.
6
Correct Answer
D. 5Explanation
An RJ-45 connector typically uses 8 wires, but only 4 of them are used for Ethernet connections. These 4 wires are paired together, resulting in a total of 2 pairs of wires. However, the question asks for the number of pairs of wires used in an RJ-45 connector, not just the number of wires. Therefore, the correct answer is 5, as there are 5 pairs of wires in an RJ-45 connector (10 individual wires in total).Rate this question:

What is the most basic encrytion used in todays wireless neywork
- A.
VPN
- B.
SSL
- C.
WEP
- D.
WPA2
Correct Answer
C. WEPExplanation
WEP (Wired Equivalent Privacy) is the most basic encryption used in today's wireless networks. It was introduced as a security protocol for Wi-Fi networks but has been widely criticized for its vulnerabilities. Despite its flaws, it is still used in some older devices or networks that have not been updated. WEP uses a shared key authentication and RC4 encryption algorithm, but it is easily cracked by attackers, making it an insecure choice for protecting wireless networks.Rate this question:

What is the recommended method of wireless encryption
- A.
WEP
- B.
WPA
- C.
SSL
- D.
PAP
Correct Answer
B. WPAExplanation
WPA (Wi-Fi Protected Access) is the recommended method of wireless encryption. It provides stronger security compared to WEP (Wired Equivalent Privacy) encryption, which is vulnerable to attacks. SSL (Secure Sockets Layer) is a protocol used for securing web communications, but it is not specifically designed for wireless encryption. PAP (Password Authentication Protocol) is an authentication method, not an encryption method, and it is considered less secure than WPA. Therefore, WPA is the correct answer as it offers better security for wireless networks.Rate this question:
