The functions of the hardware composing a computer can to divided broadly into the following five categories: Input, storage, operation, control and output.
A switch does so by having an in-built learning of the MAC address of the devices connected to it.
A bridge is a computer networking device that builds the connection with the of other bridge networks which use the some protocol.
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 thenear 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.
#4 Top IT Trend – Software-Defined Data Center
My number for trend is the software-defined data center. From the beginning
data centers will be made up of silos of server’s 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.
#3 Top IT Trend – Mobile-First
Approach
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.
#2 Top IT Trend – Machine Learning
My second top It-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.
#1 Top It Trend - The
Industrial Internet of Things (IoT)
My
top IT trends for 2016 is the internet of things specifically. The industrial
Internet of Things one study from the mckinsey global institute estimates. That
IoT 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 it’s 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

Бичлэгийн текст How To Identify The Components Inside Your Computer
My computer
Hello and welcome to videojug 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 found within the Tower of a desktop computer
they are referred to as hardware6 hardware the actual physical components that
go into 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 from factor.
Step 4 the cpu
Cpu stands for central processing unit this is the
brain of the computer and is open referred to as the processor or the chip. It
is found under a heatsink and dan and
sits 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
Ram stands for random access memory and comes as
modules and predefined amounts it is also found directly on the motherboard
usually is 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’s 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 modem 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. 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 or the computer for ease of access and use a
laser to read and write information to cds and dvds done.
