Networking
In information technology, networking is the construction, design, and use of a network, including the physical (cabling, hun, 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.

Essay 1                                      From the Barchat UK telephone calls are divided into three, Local-Fixedline, National and International-fixed line and Mobiles calls, this disquisition in 1995-2002. We need this Barchat, because mobile, telephones used for everyday Local`s figure has a 70 billion calls to 90 billion calls in increased for 1995-1999. But this figure back to decreased 70 billion calls in 1999-2002, so that now too much not used in Mongolia. National and International figure constant increase 30 billion calls to 50 billion calls in 1995-1999. Where as sharply increase to 50 billion calls to 55 billion calls in 1999-2000, since gradually increase to 55 billion calls to 60 billion calls in 2000-2002. Mobile calls were increased rapidly approximately 3 billion in 1995 to around 45 billion in 2002. Mobile phone usage was almost doubled from 22 billion minutes in 2000 to 40 billion 2001. This barchart want what to see. In my opinion in worlp people use mobile ca

The definitions and ideas applied to information and communication technologies and the modern media culture are examined in the beginning of this chapter. The characterizations of media culture are then explored from the perspective of young people, and the links between youth and ICT are investigated. The dominant cultural logic with regard to ICT is outlined, and different forms of the digital divide are presented. Some global aspects of ICT use among youth are reviewed, using both primary and secondary sources. New forms of youth socialization brought about by the emergence of ICT are examined, and the chapter concludes with a set of recommendations.       Young people today live in a world characterized by dramatic cultural, economic, social and educational differences; individual circumstances depend largely on where a person is born and raised. More than 800 million adults (two-thirds of them women) still lack basic literacy skills; at the other end of the spectrum, the use of

Essay 5    Operating system           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 –task
