What are the three categories of computing devices we studied in this chapter? (Pick 3)

• Desktop

• Notebook/Laptop

• Mobile

• Game Console

• Cable Set-top Box

Answer explanation

While there is information about gaming consoles, network clients, and servers in the chapter, desktops, notebooks / laptops, and mobile devices are the 3 main categories covered in this chapter.

Match the following jobs with the best computers for those jobs.

• Tablet

• Server (waiter / waitress)

• Mobile Phone

• Programmer

• Desktop

• Traveling Salesperson

• Laptop

• Uber Driver

• Gaming Console

• E-Sports Professional

The​ (a)   is the general "brain" of the computer while the ​ (b)   specializes in crunching numbers.

• CPU
• GPU
• RAM
• SSD

Answer explanation

The CPU (Central Processing Unit) is the main component of a computer system, responsible for carrying out instructions and performing calculations. It is the "brain" of the computer, responsible for controlling all of the other components.

The GPU (Graphics Processing Unit) is a specialized processor designed to handle graphics-intensive tasks, such as rendering 3D graphics and video. It is optimized for performing calculations related to graphics, such as lighting, shading, and texture mapping. The GPU is designed to be more efficient than the CPU at performing these types of calculations, allowing for faster and smoother graphics.

Match the following functions with their hardware components.

• Bus

• Temporary storage

• RAM

• Long-term storage

• NIC

• Network traffic

• SSD

• Internal communications

• Heat Sink

• Limiting temperatures

The ​ (a)   connects all the internal components of a computer together.

• motherboard
• cooling system
• network interface
• display
• BIOS

Answer explanation

This can cause serious harm to a computer.

• Electrostatic discharge

• Radio waves

• Sunlight

• Having a lot of browser tabs open

Answer explanation

Electrostatic discharge is when someone (or something) releases their built-up static electrity to a computer, specifically the motherboard, by touching it.

The resulting surge in electricity can seriously damage or even ruin a computer.

It is recommended that you wear a static wrist gaurd when working on computers.

What are the two major chip brands for Windows PCs?

• AMD

• Intel

• Samsung

• Potato

Answer explanation

The two major microchip brands for Windows PCs are Intel and AMD. Intel is the world's largest and highest valued semiconductor chip maker, based on revenue. Intel produces processors for desktop and laptop computers, servers, and other devices.

AMD is a major producer of processors for desktop and laptop computers, servers, and other devices. AMD processors are often used in budget and mid-range PCs.

Apple makes its own processors, including the M1 and M2 chips.

Pick examples of expansion slot cards:

• Video

• Audio

• Network

• Power

Answer explanation

Expansion slots allow users to customize and upgrade their computers.

Video, audio, and network cards are popular choices.

Power supplies would not be useful in an expansion slot as it is needed to power the motherboard, to which he expansion slots are connected.

Most computers use ​ (a)   cooling.

• air
• water
• active-liquid
• immersion

Answer explanation

Cooling is a process used to regulate the temperature of a computer. It is necessary to keep the computer from overheating and damaging its components. Cooling is typically done by using fans to draw heat away from the components and dissipate it into the air.

Some computers also use liquid-based cooling systems, which use a liquid to absorb and dissipate heat.

Motherboards connect a power supply to which of the following? (Choose all that apply.)

• Disk drives

• Expansion slots

• Hubs

• Routers

Answer explanation

Motherboards connect all the parts of a computer to a power supply. It uses a bus to exchange information between all the components.

Typical components include RAM, expansion slots, disk drives, solid state drives, CPUs, GPUs, and network interfaces.

Hubs and routers are network devices that are separate from end user devices like computers.
