Which of the following effects can be observed on computer components as a result of climate? (choose three)

A.

Components overheat if it is too hot
B.

Moisture damages computer parts if it is too humid
C.

Components works too slowly if is to cold
D.

The risk of ECD increases if the humidity is too low
E.

The risk of ECD increases if the temperature is too high

Correct Answer(s)
A. Components overheat if it is too hot
B. Moisture damages computer parts if it is too humid
D. The risk of ECD increases if the humidity is too low

Explanation
Computer components can overheat if the temperature is too hot, as excessive heat can cause damage to the components. Moisture can also damage computer parts if the humidity is too high, as it can cause corrosion and short circuits. Additionally, the risk of ECD (electrostatic discharge) increases if the humidity is too low, as low humidity can cause static electricity buildup, which can damage computer components.

Which card has 54 pins 34 pins connectoin

Correct Answer
PCI Express card
PCI Express

Explanation
The correct answer is PCI Express card. PCI Express is a high-speed serial computer expansion bus standard that uses a point-to-point architecture. It is commonly used for connecting peripheral devices, such as graphics cards, to the motherboard of a computer. A PCI Express card refers to any expansion card that utilizes the PCI Express bus interface. Therefore, it is logical to conclude that a PCI Express card would have 54 pins and 34 pins connection.

How is the speed of a laser printer measured?

A.

DPM
B.

PPM
C.

DERP
D.

DERP

Correct Answer
B. PPM

Explanation
The speed of a laser printer is measured in PPM, which stands for Pages Per Minute. This measurement indicates the number of pages that the printer can produce in one minute. The higher the PPM, the faster the printer can print documents.

What does MAN mean

A.

Mother of all Critchlow
B.

Metropolitan Area Network
C.

Mad Animal Netgear
D.

Mad Angry Nanny

Correct Answer
B. Metropolitan Area Network

Explanation
MAN stands for Metropolitan Area Network, which is a computer network that spans a larger geographical area than a local area network (LAN) but smaller than a wide area network (WAN). It is typically used to connect multiple LANs within a city or metropolitan area. The other options provided in the question, such as "Mother of all Critchlow" or "Mad Angry Nanny," do not have any relevance to the term MAN in the context of computer networking.

Which type of cable is used for Ethernet Network

A.

STP
B.

UTP
C.

Fibre Optics
D.

Coaxial

Correct Answer
B. UTP

Explanation
UTP (Unshielded Twisted Pair) cable is used for Ethernet networks. It is the most common type of cable used for Ethernet connections due to its affordability and ease of installation. UTP cable consists of four pairs of twisted copper wires, which helps to reduce electromagnetic interference. It is widely used in homes, offices, and other small to medium-sized networks for reliable data transmission.

What type of Software can be used to secure a computer against all threats

A.

Firewall
B.

Antivirus
C.

Windows Defender
D.

Automatic Update
E.

All of the above

Correct Answer
E. All of the above

Explanation
All of the above options can be used to secure a computer against all threats. A firewall helps in monitoring and controlling incoming and outgoing network traffic, protecting the computer from unauthorized access. Antivirus software detects, prevents, and removes malware, viruses, and other malicious software. Windows Defender is a built-in antivirus program in Windows operating systems that provides real-time protection against various threats. Automatic updates ensure that the computer's software and security patches are regularly updated, reducing vulnerabilities. Therefore, using all of these options together can provide comprehensive protection against different types of threats.

------------- is an attack that uses ------------ to make tracing the origin of the attack difficult.

Correct Answer
DDoS
zombies

Explanation
DDoS (Distributed Denial of Service) is an attack that overwhelms a target system with a flood of incoming traffic, making it difficult to trace the origin of the attack. The attacker typically controls a network of compromised computers, known as zombies, which are used to generate the excessive traffic. By using multiple zombies, the attacker can distribute the attack across various sources, making it harder to pinpoint the source and defend against the attack effectively.

What is the suggested maximum number of PC's in a peer-to-peer network

A.

10
B.

20
C.

25
D.

100

Correct Answer
A. 10

Explanation
The suggested maximum number of PCs in a peer-to-peer network is 10. This means that in a peer-to-peer network, it is recommended to have a maximum of 10 computers connected to each other without the need for a central server. This limitation is due to the decentralized nature of peer-to-peer networks, where each computer acts as both a client and a server. Having too many PCs in a peer-to-peer network can lead to performance issues and difficulties in managing the network effectively.
