2. Cooling Processors Require

Heat sink, fan, silicon gel

Heat sink, silicon gel

Copper core, fan

None of the above

The cooling process for processors requires a combination of a heat sink, fan, and silicon gel. A heat sink is used to absorb and dissipate heat generated by the processor, while a fan helps to circulate air and cool down the heat sink. Silicon gel is applied between the processor and the heat sink to improve thermal conductivity and transfer heat more efficiently. Therefore, all three components are necessary for effective cooling of processors.

3. The internal copper core of the heatsink is used to speed up the transfere of heat from the microprocessor

True

False

The internal copper core of the heatsink is made of a highly conductive material, which allows it to efficiently transfer heat from the microprocessor. Copper has excellent thermal conductivity properties, meaning it can quickly absorb and distribute heat. By utilizing the copper core, the heatsink can effectively remove heat from the microprocessor, preventing it from overheating and maintaining optimal performance. Therefore, the statement is true.

4. The Pentium d processor was the first Dual Core Processor?

True

False

A multi-core processor is a single computing component with two or more independent actual processors (called "cores"), which are the units that read and execute program instructions.[1] The data in the instruction tells the processor what to do. The instructions are very basic things like reading data from memory or sending data to the user display, but they are processed so rapidly that human perception experiences the results as the smooth operation of a program. Manufacturers typically integrate the cores onto a single integrated circuit die (known as a chip multiprocessor or CMP), or onto multiple dies in a single chip package.

5. How would you protect your system board components or disk drives from static electricity?

Hold on to any metallic component of the system case

Wear rubber sneakers

Work on system on a sunny day

I really dont know (lol)

What is Static Electricity? It is the accumulation of electrical charges in an object.

ElectroStatic Discharge (ESD) is the term used to describe the transfer of static electricity from one object to another.

As we go about our daily lives, we gather certain amounts of electrostatic charge. This happens mostly in low humidity areas; moreso, in winter and in dry seasons.

Our bodies also produce static electricity which is caused by excess electrons (negatively charged particles) being formed especially when we walk on carpeting.

6. What is the OEM key of Windows?

It is a key that unlocks the windows desktop

Its a key that identifies the correct manufacturer of the system

Its a key that validates windows authenticity and manufacturer

Its a key that unlocks blocked applications in windows

An original equipment manufacturer, or OEM, manufactures products or components that are purchased by a company and retailed under that purchasing company's brand name. OEM refers to the company that originally manufactured the product.

7. The best way to clear the CMOS settings of the system board is to

Change the JCMOS jumper setting

Re-install windows

Upgrade the BIOS

None of the above

8. The Master boot record is a way of orginizing files in the Operating System?

True

False

A master boot record (MBR) is a type of boot sector popularized by the IBM Personal Computer.[1] It consists of a sequence of 512 bytes located at the first sector of a data storage device such as a hard disk. MBRs are usually placed on storage devices intended for use with IBM PC-compatible systems.

The MBR may be used for one or more of the following:

Holding a partition table which describes the partitions of a storage device. In this context the boot sector may also be known as a partition sector.
Bootstrapping an operating system. The BIOS built into a PC-compatible computer loads the MBR from the storage device and passes execution to machine code instructions at the beginning of the MBR.
Uniquely identifying individual disk media, with a 32-bit disk signature, even though it may never be used by the operating system.

9. Why should you take off the front panel of the case when constructing a system?

Easier installation of front mounting fan and disk drives

Easier installation of the power supply

Because its needed in order for the front mounted components of the system board to work

No particular reason

Taking off the front panel of the case when constructing a system allows for easier installation of front mounting fan and disk drives. This is because removing the front panel provides direct access to the front of the case, making it easier to install these components. Without removing the front panel, it would be more difficult to properly install and secure the front mounting fan and disk drives in the system.

10. Why should you take out power supply when preparing a case for construction?

Make sure that static electricity does not build up

Make it easier to install the processor

Maximizing the cooling efficiency

Make it easier for placement of system board

Taking out the power supply when preparing a case for construction makes it easier for the placement of the system board. By removing the power supply, there is more space and better access to the motherboard, allowing for easier installation and connection of components. This ensures that the system board is properly aligned and securely placed within the case, which is crucial for the overall functionality and performance of the computer.
