What Hardware Is required for the computer Network?

The hardware that you need to set up your network into computers, the user interface cards, peripherals, and regardless of the data processing is needed for communicating between computers on a network.

File servers are required.They are quite quickly on computers with large amounts of RAM and storage. fast network card operating system and computer on the network if the files or programs do not have to share them here as well.

File servers is a processor of at least 800 MHz, preferably more.The hard disk must be at least 120 GB of storage. RAID is the need to store the data, if a disk problem. Backup, which may be a zip, JAZ, DAT, or CD-RW drive tape unit is necessary.

The second requirement is more than one expansion slots and network interface card (preferably fast one) is also required at least networking. 512 megabytes (MB) of random access memory (RAM). Network interface card (NIC) is going to-computer (ad hoc) network is required. All computers that are connected to the network are in parallel.

The clients are computers that have been connected to the network. A typical client is a computer that is especially cables, network software and network interface card. The computer does not require a floppy disk drive, because the files can be stored on a file server. Almost any computer can be a network workstation.

What do I need to connect your computer to a network?A router is needed for all networks data translation. This can be compared with the bridge. Router to select the best way to send a message from the destination address and the address of departure. It sends a message to a routing it considers it appropriate, after colliding with other messages. To know the addresses of Routers, computers and other network routers and bridges. They even know which parts are busier than others and redirect the data until the components are not so busy.

Repeaters are need to lose their strength, when they will be forwarded via the cable signals.The signal may be boosted and this is where the Repeater is a convenient.It sends a signal to supplement it and rebroadcast.Repeater may be as a single unit. it may be combined with the hub.This is necessary when the network cable length is more than using standard.

Providing a connection point, which is an essential cables peripherals, servers, and workstations is a device called the hub Computer networks often. authorising the yarn to each workstation, a key selector. Switches to supplement the signal, as it goes from one place to another., rather than broadcasting network packets, hubs or switches such as they are called frequently, to save your computer's address and send the information at the right location.

So you will have several components that are needed for the connection to the local area network (LAN). this device allows the establishment of the properly connected to the network and start moving data.

IP Addressing the basics tutorial-why the IP-address is required? (An interactive animation 1)

This is the first IP address of the tutorial series. It keeps track of how Internet passes the packets, network address, Classful and aliverkkoihin.

Q1 why IP address is missing?
Answer: the network connected to the phone Phones voice messages to be exchanged. All of the phone is set to a unique number.
The Internet is similar to the telephone network. IP stands for Internet Protocol. It defines the rules for the digital Internet messages to be exchanged.The computers are connected to the Internet to move messages to a smaller packages. For each computer with a unique IP address., each packet is marked in the source address and destination address.The destination address in the Internet use to pass the packets to the destination item in the source address to use.

Q2.What IP address structure?
Answer: it contains 32 bits, or four bytes (8 bits per byte). It is usually presented 4 decimal numbers, such as a.b.c.d. Each decimal place is connected to a byte.Each decimal is 0 ~ 255.
Jack's address can be, for example, present in two ways:
-Four decimal number 100.4.5.6, or
-32-bit binary number 01100100.00000100.00000101.00000110

Q3 how many IP addresses?
Answer: approximately 4.2 billion ECU (2 ^ 32 = 4, 294, 967, 296.)It looks like a lot but it is not.Internet addresses are in short supply in the beginning of the .1980 is designed for 32-bit address is known as IPv4. Later one is called IPv6 128-bit address.

Q4. What is the Internet?
Answer: Simplified definition is that the Internet is a series of routers, that connects computers and provides inter-computer communication services. Google allows you to find the "Internet", you will find a lot of good tutorials.

Q5. how the Internet will deliver messages on your computer?
Answer: the Internet has undergone a number of routers. Router has the address of the person to be included in the packages in the package labels of the network.
