Handling pressure is an important soft skill because it directly affects performance, decision-making, and relationships, especially in demanding or unpredictable environments.

Showing that you can handle pressure in a job interview is about proving it with behavior and examples, not just saying “I work well under pressure.”

- Use a concrete example (STAR method)

- Emphasize how you manage pressure

Prioritizing tasks

Staying organized

Focusing on what you can control

Taking short pauses to reset

Asking for help early rather than late

- Demonstrate it during the interview itself

Stay composed if a question is difficult

Take a moment before answering (“That’s a good question—let me think for a second.”)

Speak clearly and at a steady pace

Acknowledge challenges without becoming defensive

Calm behavior = real-time proof.

- Use pressure-related keywords (naturally)

“I stay calm and focused under tight deadlines”

“I prioritize effectively in high-pressure situations”

“I make structured decisions when information is limited”

Conclusion: The Human Side of Global Tech

# data[].attributes.body
In summary, our group believes that while technology provides the infrastructure for global collaboration, it is the human factor that determines its success.

In the fast-paced IT industry, companies cannot afford to ignore the global talent pool. However, to truly benefit from diversity, managers must look beyond software and tools. They must actively guide their teams through the stages of development, prevent Groupthink, and foster an environment where functional conflicts lead to innovation rather than division.

Ultimately, managing a global team is a balancing act: the challenges of communication and culture are real, but when handled with cultural intelligence and strategic conflict management, the potential for innovation and 24/7 productivity is unmatched.

Our final takeaway: Technology connects us, but leadership and trust unite us.

The motherboard is often called the "backbone" or "central nervous system" of a computer for a simple reason: it is the platform that allows every other piece of hardware to talk to one another. Without it, your CPU, RAM, and hard drive would just be isolated parts with no way to cooperate.

Why is it so important ?

To put it simply, the motherboard is important because it sets the limit on what your computer can do. While the CPU and GPU are the "stars" that do the heavy lifting, the motherboard is the infrastructure that supports them. If you have a weak motherboard, you can actually "choke" your high-end parts, preventing them from ever reaching their full speed.

Why are IP addresses important in a network?

# data[].attributes.body
Each device in a network has an IP (Internet Protocol) address, which acts like a mailing

address. There are two types:

• IPv4: The older format, limited to 4.3 billion addresses.

• IPv6: A newer format with a much larger address space to meet modern demands.

How do wired and wireless connections differ?

# data[].attributes.body
Differences :

-Speed and latency

-Reliability and interference

-Security

-Mobility and flexibility

Wired Connections: Provide stable and fast data transfer but low mobility.

Wireless Connections: Use radio waves to connect devices via Wi-Fi or Bluetooth and may have inteference but offer high mobility.

Idea:

the data is broken into small, discrete units called packets. Each packet contains a portion of the data plus routing information

Pros:

very efficient

allows multiple simultaneous users

reliable and resilient

scalable

# data[].attributes.body
assign unique addresses to every device for the forseeable future

allowing devices to automatically generate their own addresses, without DHCP server

simpler, more hierarchical address structure

solving the problems with Network Address Translation

bluetooth connection between 2 phones

# data[].attributes.body
all computers use one main cable

example: old ethernet networks

upsides:

cheap and easy to set up

not much cable needed

downsides:

if main cable breaks everything stops

slow when many computers

hard to find problems

# data[].attributes.body
all computers connect to one center device

example: home or office networks with a switch

upsides:

easy to add new computers

one broken cable only affects one computer

downsides:

if center device dies network dies

uses more cable

# data[].attributes.body
computers connect in a circle

example: old token ring networks

upsides:

data moves in order

no data crashes

downsides:

one break can stop whole network

hard to change

mostly not used anymore

# data[].attributes.body
computers have many connections between them

example: internet backbones, wireless mesh

upsides:

very reliable

network still works if one path fails

downsides:

very expensive

hard to manage

# data[].attributes.body
groups of star networks connected together

example: big company networks

upsides:

easy to grow

good structure

downsides:

if top part fails many users lose connection

more complex setup
