From what location are the 1st computer instructions available on boot up?
- A.
None of the below
- B.
CPU
- C.
Boot.ini
- D.
ROM Bios
Correct Answer
D. ROM BiosExplanation
ROM stands for Read-Only Memory, which is a type of computer memory that stores data that cannot be modified or erased. During boot up, the first computer instructions are available from the ROM Bios. The ROM Bios contains the firmware that initializes the computer hardware and loads the operating system. It is responsible for performing basic system checks and starting the boot process. Therefore, the correct answer is ROM Bios.Rate this question:

Missing slot covers on a computer can cause?
- A.
Overheating
- B.
EMI
- C.
Power Surges
- D.
ESD Displacement
Correct Answer
A. OverheatingExplanation
Missing slot covers on a computer can cause overheating because they prevent proper airflow within the computer case. Without slot covers, dust and debris can easily enter the computer, blocking ventilation and causing components to overheat. Overheating can lead to system instability, reduced performance, and even permanent damage to the computer's hardware. It is important to ensure that all slot covers are in place to maintain proper cooling and prevent overheating.Rate this question:

The term 10/100/1000 refers to, when dealing with a NIC?
- A.
Protocol Speed
- B.
Megabits per second
- C.
Fiber Speed
- D.
Speed of USB transfer rate (NAS ,SAN, basic external drives)
Correct Answer
B. Megabits per secondExplanation
The term 10/100/1000 refers to the speed of data transfer in megabits per second when dealing with a NIC. This indicates the maximum speed at which the network interface card can transmit and receive data over a network connection.Rate this question:

ESD would cause the most damage to the "Expansion Board"
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
ESD, or electrostatic discharge, can cause significant damage to electronic components. Expansion boards, which are additional circuit boards added to a computer system to enhance its capabilities, are particularly vulnerable to ESD. This is because they often contain sensitive components such as integrated circuits and connectors that can be easily damaged by static electricity. Therefore, it is true that ESD would cause the most damage to an expansion board.Rate this question:

A wrist grounding strap contains which of the following
- A.
Resistor
- B.
Surge protector
- C.
Violator
- D.
None of the above
Correct Answer
A. ResistorExplanation
A wrist grounding strap contains a resistor. A resistor is a passive electronic component that limits the flow of electric current. In the case of a wrist grounding strap, the resistor is used to safely discharge any static electricity that may have built up on a person's body. This helps to protect sensitive electronic equipment from damage caused by electrostatic discharge. Surge protectors and violators are not typically found in wrist grounding straps, and "None of the above" is not the correct answer in this case.Rate this question:

A computer assisted method for the recording and analyzing of existing or hypothetical systems is
- A.
Data transmission
- B.
Data processing
- C.
Data capture
- D.
Data flow
Correct Answer
D. Data flowExplanation
The correct answer is data flow because data flow refers to the movement of data between different components of a system. In the context of the given question, a computer assisted method for recording and analyzing existing or hypothetical systems would involve capturing and analyzing the flow of data within those systems. Therefore, data flow is the most appropriate option among the given choices.Rate this question:

The brain of any computer system is the
- A.
CPU
- B.
Memory
- C.
ALU
- D.
Control Unit
Correct Answer
A. CPUExplanation
The CPU, or Central Processing Unit, is often referred to as the brain of a computer system. It is responsible for executing instructions, performing calculations, and coordinating the activities of all the other hardware components. The CPU contains the control unit, ALU (Arithmetic Logic Unit), and memory. The control unit manages the flow of data and instructions within the CPU, the ALU performs arithmetic and logical operations, and the memory stores data and instructions that the CPU needs to access. Therefore, the CPU is the correct answer as it encompasses all the other options and is crucial for the functioning of a computer system.Rate this question:

The binary system uses powers of
- A.
2
- B.
4
- C.
16
- D.
32
Correct Answer
A. 2Explanation
The binary system uses powers of 2 because it is a base-2 numeral system. In this system, each digit can only have two possible values, 0 or 1. Each digit represents a power of 2, with the rightmost digit representing 2^0, the next digit representing 2^1, and so on. This means that each place value in a binary number is a power of 2, making 2 the correct answer.Rate this question:

Frames from one LAN can be transmitted to another LAN via the device
- A.
Router
- B.
Bridge
- C.
Lawnmower
- D.
Modem
Correct Answer
B. BridgeExplanation
A bridge is a device that connects two LANs and allows frames to be transmitted between them. Unlike a router, which operates at the network layer and makes decisions based on IP addresses, a bridge operates at the data link layer and uses MAC addresses to forward frames. It learns the MAC addresses of devices connected to each LAN and uses this information to determine where to send incoming frames. This allows frames from one LAN to be transmitted to another LAN via the bridge. A modem is used to connect a LAN to the internet, while a lawnmower has no relevance to LAN connectivity.Rate this question:

What is the port number for NNTP?
- A.
79
- B.
80
- C.
119
- D.
71
Correct Answer
C. 119Explanation
The correct answer is 119 because NNTP (Network News Transfer Protocol) uses port number 119 for communication. NNTP is a protocol used for the distribution, retrieval, and posting of news articles in Usenet newsgroups. Port numbers are used to identify specific processes or services that are running on a device connected to a network. In this case, port number 119 is assigned to NNTP to ensure that the communication between NNTP clients and servers is properly established.Rate this question:
