Modern IT trends
Nowadays, IT is developing day by day. Personally, I’m amazed at the technology we have available to us. It’s astounding to have the power to retrieve almost any information and communicate in a thousand different ways using a device that fits in your pocket. There’s always something new on the horizon, and we can’t help but wait and wonder what technological marvels are coming next. Technology upgrades can be delayed due to budget and time constraintsYet that might have to change as some of the biggest advances in the history of technology make their way into the front lines of service delivery. The IT trends complements are wood flooring, technology, paint, kitchen, furnishing, fashion, food trends etc. Here's an exploration of the top ten IT trends in the next half decade, including some of the latest industry data, and what the major opportunities and challenges are.
TREND 1:  SOCIAL MEDIA - SOCIAL BUSINESS AND ENTERPRISE 2.0
While mobile phones technically have a broader reach than any communications device, social media has already surpassed that workhorse of the modern enterprise, e-mail. Increasingly, the world is using social networks and other social media-based services to stay in touch, communicate, and collaborate. Now key aspects of the CRM process are being overhauled to reflect a fundamentally social world and expecting to see stellar growth in the next year. As Salesforce's Marc Benioff was very clear in his dramatic keynote at Dreamforce last month, leading organizations are becoming social enterprises.
TREND 2 : CLOUD COMPUTING
Of all the technology trends on this list, cloud computing is one of the more interesting and in my opinion, now least controversial. While there are far more reasons to adopt cloud technologies than just cost reduction, according to Mike Vizard perceptions of performance issues and lack of visibility into the stack remain one of the top issues for large enterprises. Yet, among the large enterprise CTO and CIOs I speak with, cloud computing is being adopted steadily for non-mission critical applications and some are now even beginning to downsize their data centers. Business agility, vendor choice, and access to next-generation architectures are all benefits of employing the latest cloud computing architectures, which are often radically advanced compared to their traditional enterprise brethren.
TREND 3 :  SMART PHONES
Smartphone buyers have a lot to look forward to in 2017. Devices will be thinner, faster, and perhaps a bit more intelligent than you’d like.
Virtual reality will spread to budget smartphones, and they will also have better graphics, higher resolution screens, and more storage. More than ever, you’ll be using your smartphone to pay for products and log into websites.
Deep learning could help smartphones get a fix on user behavior and improve the mobile experience. We could see a renaissance in smartphone designs, and wireless audio could replace headphone jacks in more handsets. USB-C will replace older connector and charging cables.
TREND 4 : AMAZON ECHO
The Amazon Echo is technically a Bluetooth speaker, but you wouldn’t buy one just to play music. Instead, it best serves as a Siri or Google Now for your home, a digital assistant that can tell you the weather, crawl the Web for random info, fire up some music, set alarms or calendar events, adjust a growing number of other smart home devices, and more, all upon your request.
Amazon’s done a stellar job of updating and improving the Echo since it launched late last year, and the whole thing is simple to use and operate. Like most of the devices on the list, it’s also something to gawk at. It might bring us closer to a Her-style existence, but as a friendly, hands-free bridge to the Internet, the Echo is nice to have around.
TREND 5 : ROBOTIC SURGERY
Robotic surgery, computer-assisted surgery, and robotically-assisted surgery are terms for technological developments that use robotic systems to aid in surgical procedures. Robotically-assisted surgery was developed to overcome the limitations of pre-existing minimally-invasive surgical procedures and to enhance the capabilities of surgeons performing open surgery.
In the case of enhanced open surgery, autonomous instruments (in familiar configurations) replace traditional steel tools, performing certain actions (such as rib spreading) with much smoother, feedback-controlled motions than could be achieved by a human hand. The main object of such smart instruments is to reduce or eliminate the tissue trauma traditionally associated with open surgery without requiring more than a few minutes' training on the part of surgeons. This approach seeks to improve open surgeries, particularly cardio-thoracic, that have so far not benefited from minimally-invasive techniques.

TREND 6 : RENEWED FOCUS ON OWNERSHIP AND ACCESS TO DATA AND META DATA

Control and ownership of data and metadata will emerge as a point of discussion and contention in the year ahead. That’s because data and metadata are the ‘gold dust’ that allow businesses to gain rich insights about customer behaviour, and thereby differentiate themselves in the market.
Truly digital businesses are ones that have their customers firmly in their sights. Think of the businesses that we admire for being digitally-proficient: Airbnb, Amazon, Facebook, and Google. What differentiates them is their obsession with customer service and insights. Their entire business models are focused on tracking consumers as they move through the world.
So disruptors aren’t the ones that own the technology … they’re the ones that own the customer
TREND 7 : AUTOMATION AND DEVOPS BECOMES A BUSINESS CONCERN
Earlier we defined ‘digital’ as a business model that’s built on IT. This means that automation and DevOps are no longer just relevant to application developers in the IT department – they need to be embraced at every level within the organisation.
Over the last year, there’s been a great deal of interest in new DevOps companies such as Puppet, Chef, and Terraform. With good reason. But, these new players’ technologies shouldn’t be dismissed as something of interest just to developers; we believe automation has to be at the very foundation of all IT systems and processes. We believe that if automation and DevOps become part of your business’s mindset and culture, they’ll become a source of competitive advantage.
TREND 8 : CENTRALISED TRANSACTIONAL MODELS ARE COMING UNDER ATTACK
In most industries, central ‘authorities’ exercise control over the community of participants and as a result, claim that they have a reason to charge a premium for processing transactions.
These centralised transaction models are beginning to be disrupted by peer-to-peer platforms like Blockchain, which support micro transactions that are virtually free of charge and can be performed in real time and at scale.
In the last few months we’ve seen Blockchain technology extending beyond the financial services community into the world of consumer goods and other sectors. It’s even being used to eliminate counterfeiting
TREND 9 : HYBRID IT HAS COME OF AGE
Today, the world of IT is truly hybrid. There’s no such thing as a greenfield environment, unless you’re a very small start-up. This means you need to manage a blend of on-premise and cloud-based assets ─ and your cloud assets typically won’t be delivered by a single provider.
We believe this will have implications on the skills sets that businesses require. In the world of hybrid IT you need to be able to treat your on-premise assets like software, and be skilled in managing cloud-based infrastructure and software. The focus will move from ‘units of build’ to entire workloads that are underpinned by a complete reference architecture that has been tested and validated and has clear scaling metrics. These workload reference architectures are characterised by the level of automation at the provisioning, transition, and operational cycles. The way you design and operate systems in a hybrid IT environment is vastly different – as is the breadth of skills required.
TREND 10 : 3D BIOPRINTING
3D bioprinting is the process of creating cell patterns in a confined space using 3D printing technologies, where cell function and viability are preserved within the printed construct. Generally, 3D bioprinting utilizes the layer-by-layer method to deposit materials known as Bioinks create tissue-like structures that are later used in medical and tissue engineering fieldsBioprinting covers a broad range of materials. Currently, bioprinting can be used to print tissues and organs to help research drugs and pills. In addition, 3D bioprinting has begun to incorporate the printing of scaffolds. These scaffolds can be used to regenerate joints and ligaments. The first patent related to this technology was filed in the United States in 2003 and granted in 2006

Conclusion, Anyone in the tech industry knows that making predictions about the course of technology’s future, even a year out, is an exercise in futility. Surprises can come from a number of different directions, and announced developments rarely release as they’re intended. Still, it pays to forecast what’s coming next so you can prepare your marketing strategies (or your budget) accordingly. Whatever the case may be, it’s still fun to think about everything that’s coming next.

Networking

In information technology, networking is the construction, design, and use of a network, including the physical (cabling, hub, bridge, switch, router, and so forth), the selection and use of telecommunication protocol and computer software for using and managing the network, and the establishment of operation policies and procedures related to the network.

First, So you want to set up a computer network. Right here, we have two of my computers Macbook and PC here.And they both have Ethernet ports but where do connect them to. What I need is something like this a router. Now , a router has a bunch of ports in  the back that I can connect to  multiple computers, and it also works wireless.So I can connect them with cables. A router, you can connect Macs and PCs on combined network.

        Then, These networking devices that filter traffic are called connectivity devices and they are         several different types.
   Bridge – bridge is connectivity device that forward data based  on physical address and operate at      the network access layer in the TCP/IP
   Hub – Hub is typically do not filter data , but instead incoming data packets or frames to all parts.
   Switch – A switch simplified is a smarter version of a hub
   Router – Routers are an essential part of any TCP/IP network that would be the IP addresses.

      Next, Networking types - This lesson is about most famous connection type and advantages
1.      WAN (wide area network )
Much larger than other connection types , example : whole world and it includes of the LANs and WAN
2.      MAN (metropolitian area network)
MANs connect two or more local area networks or campus area networks by connecting routers, switches and hubs (will be defined in hardware section), within the area of a single town or city.It includes mini network such as  LAN and PAN
3.      LAN (local area network )
A LAN may be either wired or wireless and is a computer network that covers a fairly small area, such as a home, office, or small group of buildings, such as a library or airport.It shows higher speed than other for sharing data resources
4.      PAN (personal area network )
A PAN is a computer network used to connect devices that are close to someone's person.Its advantage is for example you can share photos computer devices ,watch your TV from your home
5.      PN (private network )
With this network any person or company connect to each other without internet and without easily their datas of internet.
          So, think of a topology network's virtual shape in structure and computers are a home network be arranges in a circle in a family room other rooms. Network topologies are categorized into the following basic types.bus,ring,star,tree,wesh topologies. Topology remains an important part of network design they .You can probably build a home or small business computer network without understanding the differance between a bus design and star design  but becoming familiar with the standart topologies gives you a better understanding of impotant networking concept like hubs,broadcats and routers
        After that, Networking problem
First step – Nerwork adapter is properly installed and directed by the computer with no conflies.
Second – wired network verify that the network cable is properly connected and make sure the LED’s next to the jack are properly illuminated.
Wireless network if you’re using laptop with a wireless network , just look for the laptops  WiFi botton and make sure it is turned on.
       Conclusion, Networking is a process that fosters the exchange of information and ideas among individuals or groups that share common interests.When your networking is driven by shared interests, it will feel more authentic. As you can see there are many different types of computer networks in the world today. The options range from the wired to wireless to a network that only extend to a 20-30 foot radius to a network that could span accross an entire nation. Networks enable you to print an file when you are in a completely different room from your printer or to email a freind or family member in another state. The technology we have today is truly amazing and will only continue to grow and connect people from all over the world. So next time you e-mail a long-lost freind who is miles away you can thank computer networking for making it possible.

Operating System
Now, I’m going to explain the basics off an operating system. This is an interface between a computer user and hardware.It is very important as it works as a middleman making sure both hardware and software correctly.Operating systems provide a software platform on top of which other programs called application programs, can run. The application programs must be written to run on top of a particular operating system. Your choice of operating system, therefore, determines to a great extent the applications you can run. For PCs, the most popular operating systems are DOS, OS/2 and Windows, but others are availbale, such as Linux.
     First, The basic unit of software that the operating system deals with in scheduling the work done by the processor is either a process or a thread , depending on the operating system.It is processes rather than applications, that the operating system controls and schedules for execution by the CPU. In a single –tasking system, the schedule is straight forward.The operating system allows the application to begin running, suspending the execudion only long enough to deal with internepts and user input process management is an integral part of any modern day operating system the  OSmust allocate resources the processes, enable processes to share and exchange information product the resources of each process from other processes and enable synchronization among process. To meet these requirement is the as must  mountain a data structure for each process, which describes the state and resource ownership of that process, and which enables the OS to exert  control over each process.
Next, Popular operating systems
The three most popular types of operating systems for personal and businesses computing include Linux, windows and Mac
·       Linux operating systems
Linux is a freely distributed open source operating system that runs on a number of hardware platforms. The Linux kernel was developed mainly by Linus Torvalds and it is based on Unix.
·        Mac Operating Systems
Mac OS is official name of the Apple Macintosh operating system. Mac OS features a graphical         user interface (GUI) that utilizies windows, icons and all applications that run on a Macintosh             computer have a similar user interface.
·         Windows operating system
Microsoft Windows is a family of operating systems for personal and business computers. Windows dominates the personal computer world, offering a graphical user interface (GUI), virtual memory management, multitasking and support many peripheral devices
Then, There are four  essential managers of every OS and they all work together like team to get jobs completed. An operating system is simple term it’s chief program that manages all of the hardware and software . It is works as their bass and makes sure they are all working in harmony.
  1.   Memory management is the function that controlling and coordinating memory location and either allocated or free blocks to various programms to optimize overall system performance. There are 4 types of technique ways to manage memory.
1.      Single contiguous allocation
2.      Partitioned allocation
3.      Paged memory management
4.      Segmented memory management
All this techniques has their own advantages on their own. In hardware memory management involves components that physically store data, such as RAM (Random Access Memory ), VRAM (Virtual RAM), GRAM (Graphical RAM), chips, memory caches and flash based SSDs (Solid Star Drives)
2.    Device manager is control panel applet in Microsoft Windows operating systems it allows users to view and control the hardware attached to the computer. Hardware devices typically provide the ability to input data into the computer output data from the computer. Device manager is a feature of Microsoft Windows that detects and lists hardware devices and their status information. Device Manager is available in Microsoft Windows 95, 98, ME, 2000, 2003, XP, Vista, 7, 8, and 10.Device management does the following activities for device manager.Keeps track of all devices, decides which process gets the device allocates way, de-allocated device. Device manager important to make sure it’s well designed.
3.    A file manager or file browser is a computer program that providers a user interface to  and folders.It has limited capalities and is designed to manage individual or group files, such as special office documents and records. A file management sustems is also known as a file manager.File manager is a software program that helps a user manage all the files on their computer.For example, all the managers allow the user to view, edit, copy and delete the files on their computer.
4. Network management is the process of administering and managing the computer networks of one or many organisations. Various services provided by network managers include fault analysis, performance management, provisioning of network and network devices.
5.     The Process manager  is an integral part of any modern-day operating system (OS). The OS must allocate resources to processes, enable processes to share and exchange information, protect the resources of each process from other processes and enable synchronization among processes.
Ø    
Finally, Operating systems provide a software platform on top of which other programs called application programs, can run. It is very important as it works as a middleman making sure both hardware and software correctly. Without an operating system, a computer useless.

A lot of people say about the effects of technology and communication.
Do you agree or disagree?
           It is true,that technology in recent years has altered the path that people communicate with each other. There are many ways that technology affects our relationships, and in my opinion, this is a beneficial development.Technology such as email, Facebook, Twitter, My Space, YouTube, Instagram and many other sites are all amazing tools that have the intent to bring inter-connectedness around the world. Everything has two sides, and the ‘effects of technology on people’s relationship’ is not an exception.

            In ancient times, people used letters and telegrams to interact with each other. With the advent of modern communication systems like telephone and the Internet, people can collaborate more effectively. To begin with, the most obvious transformation in people relationships is how they communicate with each other. By this, I mean that the Internet has converted the world into a small village and nowadays people around the world can reach each other easily and rapidly. For example, a friend who lives in the UK can chat and talk with their friends in china using a mobile phone or social network and we can interact through emails rather than letter and businessman can have online meetings through the conference calls.

            On the other hand, many people believe that technological aspects are affecting individual relationship badly. They opine that, if we did not have these kinds of technology, we would have been visiting each other regularly.
            Not only that, but individuals will not be isolated from each other, especially those who are addicted to using social networking platforms.  As a matter of fact, people become talking to each other in face-to-face method rarely. In particular, people’s personalities are changing so much, because of addiction in using Facebook. It’s one of the vital reasons to decrease confidence and self-esteem.
               Everything has two sides of advantage and disadvantage.In many positive ways, the technology has affected the relationships between people and I would say these are positive developments. Imagine without technology, what would happen to the people and the world. In many ways, we are getting the help of using technology. 
              After all, in my viewpoint, humankind can eventually address this issue in favour of his civilisation. Hence, I assume it as a mainly positive development in the long run.
