1. what is the difference between a surge protector and a power strip?

Explanation:

1. Vocabulary Definitions:

a. Router:

A device that connects multiple computer networks, directing data traffic between them (e.g., connecting a home network to the internet).

b. Ports:

Physical or virtual interfaces on a computer/device to connect peripherals (e.g., USB, Ethernet ports) or transfer data.

c. Peripherals:

External devices (e.g., keyboard, printer, mouse) connected to a computer to enhance its functionality.

d. USB:

Universal Serial Bus, a standard interface for connecting peripherals (e.g., flash drives, keyboards) and transferring data/power.

e. Surge:

A sudden, brief increase in electrical voltage, which can damage electronic devices.

f. Surge protector:

A device that protects electronics from voltage surges by diverting excess voltage to the ground.

g. Ethernet cable:

A cable used to connect devices (e.g., computers, routers) in a local area network (LAN) for high-speed data transfer.

h. Boot:

The process of starting a computer, loading the operating system, and preparing it for use.

i. Antivirus software:

Software that detects, prevents, and removes malware (e.g., viruses, trojans) from a computer.

j. Driver:

Software that enables communication between an operating system and hardware devices (e.g., printer, graphics card).

2. Difference between Surge Protector and Power Strip:

• Power Strip: Primarily a device to expand the number of electrical outlets, allowing multiple devices to be plugged in. It does not protect against voltage surges.
• Surge Protector: In addition to providing multiple outlets, it includes surge protection circuitry to safeguard connected devices from voltage spikes/surges.
