What kind of RAM fits on a laptop motherboard
Correct Answer
B. SODIMM
Explanation
SODIMM stands for Small Outline Dual In-Line Memory Module. It is a type of RAM that is specifically designed to fit on laptop motherboards. Unlike regular DIMM modules, which are used in desktop computers, SODIMMs are smaller in size and have a different pin configuration that allows them to be compatible with the limited space available in laptops. Therefore, SODIMM is the correct answer as it is the type of RAM that fits on a laptop motherboard.

.................. allows the program to be broken into smaller parts that can be loaded as needed by the operating system. It also allows individual programs to be multitasked.
Correct Answer
A. Multithreading
Explanation
Multithreading allows a program to be divided into smaller parts called threads, which can be loaded as needed by the operating system. This allows for better utilization of system resources and enables individual programs to perform multiple tasks simultaneously, known as multitasking.

What are the two files NTLDR loads to make up the core of Windows XP?
Correct Answer
ntoskrnl.exe hal.dll
ntoskrnl hal
goats cheese

The total distance of cable (In Miles) on an FDDI dual ring is.....
Correct Answer
B. 62 Miles
Explanation
The correct answer is 62 Miles. FDDI (Fiber Distributed Data Interface) is a network technology that uses dual rings for data transmission. Each ring has a length of 30 miles, and they are connected to form a complete loop. Therefore, the total distance of cable on an FDDI dual ring is twice the length of one ring, which is 60 miles.
14.
What breaks the signal, changing from data mode to command mode.
Correct Answer
AT+++
Explanation
The sequence "AT+++" breaks the signal and changes it from data mode to command mode. This is because the "AT" prefix is commonly used in modem commands, and the "+++" sequence is a special escape sequence that tells the modem to switch from data mode to command mode.
15.
Biometric Sensors...........................
Correct Answer
D. Identify the user's physical characteristics, such as fingerprints or retinas
Explanation
The correct answer is "Identify the user's physical characteristics, such as fingerprints or retinas." This is because biometric sensors are specifically designed to capture and analyze unique physical characteristics of individuals, such as fingerprints or retinas. These characteristics are then used to verify the identity of the user and grant access to a system or device.

What has an aspect ratio of 11:6?
Correct Answer
EGA
Explanation
EGA (Enhanced Graphics Adapter) is a computer display standard that was introduced in the 1980s. It has an aspect ratio of 11:6, which means that for every 11 units of width, there are 6 units of height.
