Networking (subtitle)
Unique number to each one techie
people call this an IP address a router also connects to the internet outside
your home via a modem that can be provided by your or cable internet provider.
A router is always at work managing the tons and tons of information your
computers and devices send and receive and controlling which computers and
devices get what information and when so how does a router actually send
information from the internet to your computers and devices and how does it
enable your computers to share information with each other the answer lies with
that device we mentioned earlier a switch a switch sins traffic through your
network to the places it needs to go every home router has a switch with four ports built right into it
you can also get wireless routers from that use radio signals to do the same
thing as a switch but these still have those four ports built into them so you
can use wires with them too when you're buying a router for use in a wire.
Network pay attention to the speed of the built-in switch the fastest switches
are called gigabit and they're perfect for applications like streaming video in
your home meanwhile routers switches called fast ethernet are great for
essential tasks like web surfing email and online gaming now say you have more
than four idea as you'd like to plug into a router you need more ports the
solution is easy you'll need an additional switch which again is that thing
that's already built into your router in this case though you just need to
switch portion and not another router because your network doesn't need two
brains after all has switches with as few as five ports as well as some that
feature 24 ports or more once again if you need the fastest speeds go for a
gigabit switch your smarty pants router will recognize these new connections
and start sending data to them right away here's one more thing to keep in mind
some people often confuse a switch with a related device called a hub which is
obsolete you just need to know that hubs were replaced by switches because
switches do the same thing but with a lot more speed and smarts a router a
switch and network cables all come together to create a fast and reliable wired
network that works a lot like your body's nervous system fortunately you don't
have to be super brainy to understand how it all works.
Modern IT (subtitle)
In my role distribution
can it's important to love five years out to see. What industry is headed in
the long term but much of my attention is focused on the near future
identifying the technology and trends that are ready to be put to use a tablet
over the next 12 months with that in mind here for the top IT trends that I
believe a poised to gain real traction in 2016 my number for trend is the
software-defined data center from the beginning data centers will be made up of
silos of servers storage and networking hard way but that model is redundant
and expensive and it makes it difficult to allocate resources quickly that's a
problem for IT teams that are feeling pressure to improve responsiveness and
decrease maintenance costs in a software-defined data center all the essential
elements of a computing platform a pool together virtualized and managed to a
common set of application programming interfaces with all of the data centers
resources pulled together it's easier and faster to monitor and reallocate
compute storage network in and even security resources according to the needs
of the business production-ready software-defined data center offerings and now
available from established vendors as well as from new cameras and I tea shops
are looking for safe and proven ways to move to a software-defined environment
that delivers the stability and the agility that their businesses require my
number three top trend is what I call a mobile first approach until now most
mobility initiatives will focus on providing mobile devices with the same
access and security that we find on desktop and laptop PCs the mobile versus
approach turns out world view on its head it's not about matching the PC
experience and a small device anymore it's about getting the most of the unique
advantages that mobile platforms have to offer such as the ability to easily
capture pictures documents and also knowing the precise location of the device
as mobile devices get more convenient security with a broader adoption of
biometrics I expect more businesses will be thinking mobile-first in 2016 for
both customers and employees my second top i t-tried 4 2016 is machine learning
I see machine learning is a logical evolution of the exponential growth of data
and data analytics that we've been seen over the last few years big data and
data analytics today are mostly concerned with mine in large quantities of data
to provide insights that leaders can use to make informed decisions with speed
however those results of focus on helping business leaders interpret past
activity a machine learning on the other hand is about using the same data sets
to predict future behavior today Google Facebook and Amazon or relying on
machine learning to deliver content ads and products that use your past
activity to predict what you'll be interested in next IBM's Watson initiative
extends its significant machine learning capabilities to IBM customers a
machine learning is also at the heart of Google's efforts to develop
self-driving vehicles as the engineers at Google will tell you it's easier to
drive a car when you can predict what's around the corner rather than having to
focus on the road behind you and running the business is no different that's
why i believe machine learning will be one of this year's top trends to gain
traction as organizations like to predict the future as well as they can
analyze the past my top IT trends for 2016 is the internet of things
specifically the industrial Internet of Things one study from the global
institute estimates that I OT will deliver up to 11 trillion dollars of global
economic impact on an annual basis just 10 years from now and a significant
proportion of that was going to be made up the industrial IOT for example one
of a minute industrial equipment customers has begun in bed in connected
sensors into the field based equipment this gives our customers the ability to
let maintenance teams know when a component is about to break down but before
it actually happens this simple warning helps avoid costly downtime and
emergency repairs it also ensures that the service technicians have exactly the
right parts they need when they arrive on site 2016 will be the year the IOT
hits critical mass the opportunity is simply too large for that but the
building blocks for the ecosystem and now in place making it easier faster and
less expensive to prototype and roll out real world I OT solutions that's why
its my number-one trend for 2016 to find out how these and other top technology
trends are being applied inside the enterprise in the year to come stay tuned
to this text and series and to my blog behind the firewall and don't forget to
give us a thumbs up or post a comment below this video is a value to you thank
you for watching and see you next time.
Computer components (subtitle)
A guide to the components inside my computer hello and welcome to
video we're going to show you what the major components inside your computer are and tell you a little about what each
of them do guiding us on this tour will be Phil Borton of East a
technology support in brighton. Step 1 the major components the major
components of a computer are the motherboard the CPU or central processing unit
ram or the random access memory the graphics card the power supply the hard
disk or hard drive the optical drive also known as a CD or DVD drive. Step 2
hardware and software all of these components are usually found with in the Tower of a desktop computer. They are
referred to as hardware can be thought of as the actual physical components
that go into the computer software refers to the programs and systems that
operate within the hardware. Step 3 the motherboard the motherboard is the
heart of the computer it is the largest and most fundamental component of a pc
and every other component is attached to it in some way. This is because all
the different components used the mother board to communicate and work with
each other the motherboard has a series of slots sockets and connectors for
attaching the components of a pc in most cases the memory accessory cards and
CPU are installed directly onto the motherboard. The drives and peripherals
communicate with the motherboard through wired connections there are a wide
range of motherboards to choose from they different features speed capacity and
the CPU supported. They also different size shape and layout this is commonly
referred to as the form factor step for the CPU stands for central processing
unit. This is the brain of the computer and is often referred to as the
processor or the chip. It is found under a heatsink and fan directly on the
motherboard the CPU directs coordinates and communicates with the other
components and performs all of the thinking. It is not really thinking what a CPU
actually does it perform mathematical calculations it is the software that
people write that translates these calculations into useful functions for us. Step
5 RAM stands for random access memory and comes as modules and predefined
amounts. It is also found directly on the motherboard and usually in one two or
four slots the memory chip store information temporarily for short term used by
the CPU. RAM is used to store
information for files that are actually being used by the CPU at any given time
the computer.
RAM memory is an entirely different thing from
the hard disk memory the hard this stores information permanently for long-term
use. Step 6 the graphics card the graphics card or video card translates information
into the graphics and tax that appear on the monitor screen most motherboards
now include a slot specifically designed for the graphics adapter called the
AGP slot. This stands for advanced graphics port modern graphics adapters
usually incorporate some memory write on the card to improve their performance.
Step 7 the power supply this supplies power to the other components which is why
it has so many wires coming out of it is usually positioned at the back top
corner of the computer case the power supply has a fan built into it to keep
itself and the computer cool. Step 8 the hard disk a hard disk which is also
called a hard drive is much like a filing cabinet the programs and data is
stored on the hard disk and the computer accesses them as they are needed when
the computer accesses the hard drive. It is reading and moving the stored
information into the ram memory that memory is the temporary workspace however
the original file is still on the hard disk and has left undisturbed until the
file is saved when the computer stores or saves information it writes a data to
the hard disk that process results in the old file being replaced or modified
with the new information if you save data to a new file or install new software.
The information is written to the disc in an available unused portion of the disk.
Step 9 the optical drive the optical drive is often called a DVD drive or a CD
drive it sits at the front of the computer for ease of access and use a laser
to read and write information to CDs and DVDs done.

worked for previously. I think my vision goes toward the big picture and I want
to exploit that talent to the best of my ability.
11.What's the most important thing you learned in school?
The
most important thing I learned was to accept and respond to feedback. The
critique I received from peers and professors greatly enhanced my growth. It
was challenging to present my work to others and hear their opinions about it,
but I quickly realized that whether their comments were positive or highlighted
needed improvements, the intent was to help me become more capable and
effective. These experiences also taught me to critique others using language
that focuses on quality and shared goals, avoiding comments that could be
interpreted as personal or overly critical.
12. Why did
you choose your major? I chose to be an engineer because I thought it would be a
lot of fun! Engineering is the field that solves the most impactful of our problems
in the world, like creating clean energy or detecting cancer. As engineers, we
are constantly changing the world with inventions and solutions that affect
everyone's lives. We get to dream up all the coolest gadgets, then we get to go
into the lab and actually make them.
Engineers are like the wizards of our society. Being an engineer is fun
because I get to use magic to create things every day. One day, I'll make
something that can help change the world, and that's why I wanted to become an
engineer.
13.Tell me about your proudest achievement? My proudest accomplishment would have to be when I helped
develop a new technique at my last job. We had been working the same way for
ten years. One day, I was watching one of my coworkers use the old technique
and realized that there was a much more efficient way to get the job done. With
the help of my supervisor and a couple other coworkers we came up with a new
technique. It was such a rush to come to work and see people getting trained to
do something that I helped develop.
14.
What kind of personality do
you work best with and why?
I work well with many
different personality types. I have encountered various types of workers, and I
find that as long as everyone has a clear understanding of the goal and work
together to accomplish it, we are all able to thrive and accomplish the task at
hand.
15. How do you want to improve yourself in the next year?
At the
moment, I’m learning to speak English in order to make it easier to communicate
with a larger number of people. I’m also focused on developing my technical
skills so I can pursue an interest in programming in the future, particularly
since a lot of the knowledge I pick up will benefit me professionally as well.
16. What
kind of goals would you have in mind if you got this job? In the near term, I
would like to develop myself to become the best possible, learning as much as I
can about the role and about how I can best serve the needs of the department
and the company. In the longer-term, I would like to become a subject matter
expert in an area of greatest need within my role. I would like to develop to
the point that I become that go-to person whom others rely upon for the most
current information. And eventually I would like to become a lead and mentor to
help others developing in their respective roles.
17. What techniques and tools do you use to keep yourself
organized? Keeping my desk clutter free help keeps my mind clutter free. I am also
keen on ensuring all planned tasks are recorded in at least two mediums.
Usually on the computer's calendar and by hand in my work diary. Through my
experience I have found that filing papers as soon as they become available to
me, instead of letting them build in my in tray, is a much more efficient way
to stay organized.
18. Was there a person in your career who really made a
difference? The person who made the biggest difference in my career was my coworker
Tuya. She and I started at the same time. We were both so green and
inexperienced. She helped to push me to better myself and showed me the
importance of continued education even in the workplace. I was excited about
this field before I started working, I wanted to give my best. If I hadn’t have
started out with Tuya, I don’t know where I would be now. She really helped me
set goals and then go through and achieve them. We didn’t work together that
long, but even in a short time he really made a difference.
19. Who has impacted you most in your career and how? If I had to choose
someone that impacted my career, it would have to be my first manager. I was
fresh out of university, eager to learn. I was lucky, my first manager was an
amazing leader. She directly taught me about the industry, aiding in my
learning process. She had twenty-two years experience at the time, I really
respected her. I learned so much
indirectly. She was the perfect example of how you can effectively run a team.
I picked up on her leadership skills. Everyone within our team respected her
because she respected everyone in return. Once my career developed, I started
at a new company. Due to the knowledge she provided, I successfully became a
management team leader. Although I am highly driven and passionate, the skills
she taught me had a large impact on my career. I have received various awards,
and now help teams develop into strong, co-operative units.
20. Have you ever been on a team where someone was not
pulling their own weight? How did you handle it? During a recent project, one
co-worker regularly failed to complete his assigned tasks by the necessary
deadlines. I explained to him privately that this resulted in other people on
the team picking up his work, in addition to their own, which felt unfair. I
asked if there was a reason for this issue and he explained that he couldn’t
keep up with the deadlines because his knowledge of the relevant software
wasn’t strong. We arranged for training and additional support so that he could
work more efficiently.
21. What attracted you to this company? I have been watching
this company for a long time. I read this article a year ago about how you are
innovating the way people use appliances, and that really caught my eye. I
think that innovation and creativity are an important part of success. I would
be so excited to be a part of that innovation here. Not only the innovativeness
of the company attract me, but also the way they treat their employees. I have
a friend who works here, and she just raves about how well she is treated and
how the company feels like a family. I would love to work somewhere where I can
be that close with my coworkers.
22. What was the last project you headed up, and what was
its outcome? My last project was to pull together a working group to analyze find ways
to streamline our supply options at the small laptop computer company I worked
at. I worked with the production artists and accounting people to find the best
fair trade solutions for the volume we were purchasing. We ended up with both
the best choice for our situation at the time and a plan to scale our supply
chain as our sales increased, giving us a little more out of the research than
we originally planned on.
23. What are three positive things your last boss would
say about you? At my last job, I had a strong reputation as the knowledgeable employee. I
had the book memorized and people would almost use me as an encyclopedia. I
also never had any trouble meeting time restraints. I was never late or missed
a deadline. Of course, I think my boss would also bring up that I was great
with the customers as well.
24. List five words that describe your character? The five words that I
feel best describe me are resilient, ambitious, optimistic, determined and
humble. I was the first person in my family to go to college, and along with
their support, these personality traits really helped me get through school and
appreciate the opportunities I’ve been given. I feel that they would help me
succeed in this job as well.
25. Why do you want this job? I see this company not only as a
positive work environment, but also as a good opportunity to have my skills and
qualifications make a difference. This position challenges me to keep up with
the cutting edge of technologies.
