IP Address



IP Address
What is in common between DNS - the Domain Name System, and IP addresses? It is the fact that the DNS is an Internet service that translates domain names/hostnames to IP addresses (forward DNS) and IP addresses to their associated domain names/hostnames (Reverse DNS) with the help of a DNS server.

This is one of the crucial services on the Internet, greatly facilitating the access of users to websites, by helping each visitor refer to the desired websiteonly by typing its alpha-numeric name (domain name) in the browser instead of its real numeric system name (IP address). 
IP address
Each machine, which is connected to the Internet, has its own IP address. The IP address is used to identify it to the world and plays an important part in the TCP/IP protocol. Usually, an IP address is displayed as a group of numbers, separated by dots:


IP address structure and classification

IP address structure and classification


A typical IPv4 address
216.65.1.250
The numbers in the IP address are called octets. The name "octets" derives from the positions the numbers can have in the binary form of the IP address, which is actually used by computers. The "216.65.1.250" type of address is used for human understanding. Here is how the IP address of the above example will look in binary format:


An IP address in binary format
001100100011000100110110001011100011011000110101
001011100011000100101110001100100011010100110000
Classes of IPv4 addresses
The octets in the IP address play another important role - they divide the IP addresses into classes. They are split into two sections - net and host. The Net section always starts with the first octet and is used to define the network the machine belongs to. The Host section defines the actual machine in the network and always contains the last octet. 

Class A IP addresses
The class A IP addresses have a first or Net octet in the range of 1 and 126. The other three octets define the hosts. The A class network allows for a total of 2,147,483,648 unique IP addresses and is mainly used for the network of a very large corporation.
A class A IP address
Net                  Host
123.                 23.41.88
Class B IP addresses
The class B IP addresses use the first two octets as network identifiers, and the last two as host identifiers. The first octet in the class B IP addresses is in the 128 to 191 range. IPs from this class are most commonly used by mid-sized networks, such as college campuses
A class B IP address
Net                  Host
133.23.            41.88
Class C IP addresses
For this class, the Net identifier is composed of the first 3 octets and the first octet is in the 192 to 223 range. The last octet is used to identify the host. With a limited number of hosts, this IP class is suitable for small to mid-sized networks.
A class C IP address
Net                  Host
196.23.41.       88
Class D IP addresses
IP addresses from this class are mostly used for multicasting. They are in the 224.0.0.0 to 239.255.255.255 range. The 224.0.0.0 to 224.0.0.255 range is used only for local area network (LAN) multicasting. 
Class E IP addresses
IP addresses in this class have the first octet in the 240-255 range. They are reserved for experimental usage and computers, trying to use them will not be able to communicate properly online.


IPv6 addresses
When looking at a standard IPv4 address, one can easily see that it has a finite number of combinations for unique IP addresses and that at some point, they will be over. This is why the IPv6 IP address was created.


A sample IPv6 address
2001:0db8:3c4d:0015:0000:0000:abcd:ef12
The IPv6 address is expected to launch worldwide in late 2010 or 2011, when the IPv4 addresses will reach their limit. The new address is of 128 bits (IPv4 is 32bit), which will be enough for at least 100 years in the future, even if the growth of the Internet users increases.


Reverse IP address lookup
It is possible for any user to find which IP address is associated with a certain domain name/hostname and vice versa with the help of an online DNS lookuptool. How does such a search tool work? When a DNS lookup request is sent by typing a certain domain name in the tool's search field, the DNS serversearches the DNS database to locate the IP address that the domain is associated with and then returns the desired result back to you.

4 main parts of a computer


If you own a computer, it’s important to familiarize yourself with the ins and outs of your system. You don’t need to know how to change the oil in your car, for example, but you should know that it needs to be done.
Basic computers are broken down into four pieces of hardware.
Hard drive: This is known as storage. All your programs and data are stored on your hard drive. This is like your stomach. Fill it too much and things will slow down. Realize that we typically have hard drives that are bigger than we’ll ever need in our lifetime.
Memory: You can equate a computer’s memory to your memory. A computer with plenty of memory is like a person with great memory. A computer with too little memory is like a human that has to use a notepad too much.
Case: The case is simply the body that everything sits in. Check out your computer case. It’s built pretty intelligently. For example, if you have a mouse with a round connector (PS2), then the connector is probably green and there is only one green round connection point on the motherboard for it. This is typical of anything that connects to the computer – there is only one place to connect it.
Motherboard: You could equate a motherboard to a spinal cord. Not only does everything plug into it, but this is also how everything communicates. Most of the motherboard is hidden from view and is only exposed at the rear of the computer.

Troubleshooting Tips for New Monitors

You are encouraged to make links to this article from your website and tell your friends

Here are some basic trouble shooting tips for new monitors:
  1. The picture does not appear
    • Check to make sure the signal cable is firmly connected in the socket.
    • Check to see if the computer system's power is ON.
    • Check that the Brightness Control is at the appropriate position, not at the minimum.
  2. The Screen is not synchronized
    • Check to make sure the signal cable is firmly connected in the socket.
    • Check that the output level matches the input level of your computer.
    • Make sure the signal timing of the computer system is within the specification of the monitor.
  3. The position of the screen is not in the center
    • Adjust the H-Size, H-Phase or V-Size, V-Center controls.
    • Check if the signal timing of the computer system is within the specification of the monitor.
  4. The screen is too bright or too dark
    • Check if the Brightness or contrast control is at the appropriate position, not at the maximum or minimum.
    • Check if the specified voltage is applied
    • Check if the signal timing of the computer system is within the specification of the monitor.
    • Especially, check the horizontal frequency.
  5. The screen is shaking
    • Move all objects that emit a magnetic field, such as a motor or transformer, away from the monitor.
    • Check if the specified voltage is applied.
    • Check if the signal timing of the computer system is within the specification of the monitor.

Common Troubleshooting Techniques & Strategies


You are encouraged to make links to this article from your website and tell your friends



Here are five common-sense techniques and strategies to solve common computer hardware problems.

(1) Trial-and-error

Personal computers are highly modular by design. The most powerful trouble-shooting technique is to isolate the problem to a specific component by trial-and-error. Swap compatible components and see if the system still works. Try different peripherals on different machines and see if the same problem occurs. Make one change at a time.

(2) "It's the cable, s-----."

More than 70% of all computer problems are related to cabling and connections. Ensure all cables are connected firmly. IDE and floppy ribbon cables and power cables can often go loose. Ensure microprocessor, memory modules, and adapters such as video card and sound card are inserted correctly and didn't "pop-up" during transportation.

(3) Don't be frustrated!

Don't be afraid of computer problems. It is often the best opportunity to learn. Trouble-shooting is part of the fun of owning a computer. Imagine the satisfaction you could get by solving a problem yourself.

Of course the fun could ran out quickly once you are frustrated and have spent too much time on the same problem. If you feel frustrated, it's time to leave it for a while and go back with some new ideas or call someone who can help. Rule of thumb: You shouldn't spend more than three hours on the same problem at one time.

(4) Take notes!

Take notes of what you have done and all the error messages. You may need to use them later. For instance, when you see an unusual blue screen with an error message, copy the entire message onto a piece of paper. In many situations, that message may point to the right direction in getting the problem solved quickly.

(5) Take a look?

It's OK to open a computer case and take a look inside. There is only 5V and 12V DC voltage supplied to the components outside the power supply. Those who have never seen the inside of a computer are often amazed by how simple it looks. Of course, still always power down and unplug the power cord first.

central processing unit (CPU) - Interprets and carries out basic instructions that operate a computer

Heat sink—component with fins that cools processor

random access memory (RAM) - Memory chips that can be read from and written  to by processor.  Also called main memory or primary storage.  Most RAM is volatile, it is lost when computer’s power is turned off.

read-only memory (ROM) - Memory chips that store permanent data and instructions.  Nonvolatile memory, it is not lost when computer’s power is turned off.

basic input and output system (BIOS) -  the first program to run when you turn on your computer.  It is stored in a ROM chip on the motherboard.

complementary metal-oxide semiconductor memory (CMOS) - Stores date, time, and  computer’s startup information.  Maintained by a small battery after you turn the computer off.

adapter card - Enhances system unit or provides connections to external devices called peripherals.  Also called an expansion card.

expansion slot - An opening, or socket, on the motherboard that can hold an adapter card

Port connects external devices to system unit
Connector joins cable to peripheral
