Ping vs Traceroute 

Ping

Ping (also written as PING or ping) is a utility that you use to determine whether or not a specific IP address is accessible. Ping works by sending a packet to a specified address and waiting for a reply. Ping is used primarily to troubleshoot Internet connections and there are many freeware and shareware Ping utilities available for download.

On a Windows PC you can run Ping using a command prompt. To do this, go to the Windows Start button, choose Programs, then MSDOS Prompt. When you get the C: prompt, type ping followed by the destination server name or an IP address, for example, ping google.com

Ping Localhost

When setting up a network you can use the ping command to make sure all of the computers are "alive" (at least in the TCP/IP sense). To do this, go to the Windows Start button, choose Programs, then MSDOS Prompt. When you get the C: prompt, type ping 127.0.0.1

If everything is OK, you should get the following response (or something similar):

Pinging 127.0.0.1 with 32 bytes of data

Reply from 127.0.0.1: bytes=32 time<10ms TTL=32
Reply from 127.0.0.1: bytes=32 time<10ms TTL=32
Reply from 127.0.0.1: bytes=32 time<10ms TTL=32
Reply from 127.0.0.1: bytes=32 time<10ms TTL=32

This means that TCP/IP is working on the machine that you are typing on. 127.0.0.1 is a special address that "loops back" to the machine you are pinging from. You can also type ping localhost and receive a similar response, since localhost and 127.0.0.1 mean the same thing.

Traceroute

Traceroute is a utility that traces a packet from your computer to an Internet host, but it will show you how many hops the packet requires to reach the host and how long each hop takes. If you're visiting a Web site and pages are appearing slowly, you can use traceroute to figure out where the longest delays are occurring. Traceroute utilities work by sending packets with low time-to-live (TTL) fields. The TTL value specifies how many hops the packet is allowed before it is returned. When a packet can't reach its destination because the TTL value is too low, the last host returns the packet and identifies itself. By sending a series of packets and incrementing the TTL value with each successive packet, traceroute finds out who all the intermediary hosts are.
The original traceroute is a UNIX utility, but nearly all platforms have something similar. Windows includes a traceroute utility called tracert. On a Windows PC you can run traceroute using a command prompt To do this, go to the Windows Start button, choose Programs, then MSDOS Prompt. When you get the C: prompt, type tracert followed by the destination server name or an IP address, for example: tracert google.com

Ip Address

IP Address

IP address is short for Internet Protocol (IP) address. An IP address is an identifier for a computer or device on a TCP/IP network.

Static Versus Dynamic IP Addresses:

An IP address can be static or dynamic. A static IP address will never change and it is a permanent Internet address. A dynamic IP address is a temporary address that is assigned each time a computer or device accesses the Internet.

What is My IP Address?

To view your IP address you can use the ipconfig (IPCONFIG) command line tool.  Ipconfig displays all current TCP/IP network configuration values and refreshes Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings.

To launch the command prompt from a Windows-based computer click: Start > All Programs > Accessories > Command Prompt. Type ipconfig and press the Enter key.

• You can also use Google search to find your IP address. Type "what is my IP address" as a search query and Google will show the IP address of the computer from which the query was received as the top search result.

 A computer processor, also known as a microprocessor or central processing unit (CPU), is a component in a computer system that functions as the brains of a computer. It is mainly responsible for processing instructions of a computer program and carrying out computer operations
Intel Pentium Dual core CPU LogoIntel Pentium Dual Core Processors


The Intel Pentium processors with Intel dual-core technology deliver great desktop performance, low power enhancements, and multitasking for everyday computing.

Intel Dual Core i3 CPU  (Ivy Bridge)
Intel Core i3 dual core processors provide 4-way multitasking capability, runs at fixed speed ideal for typical tasks and media playback but not games.


Intel Dual Core i5 CPU  Processors
Intel i5 usually quad core but some dual processors deliver the next level of productivity. Mostly the same as i3 but with Intel Turbo Boost Technology, delivers extra speed when you need it. Like the i3 integrated graphics is included but is only ideal for normal use not for gaming.




Intel Dual Core i7 CPU Processors
Intel i7 processors dual or quad core for the most demanding applications with cache and faster clock speeds. Quad-core processors feature 8-way threading, four cores will run faster, and more L3 cache, but will consume more power. High-end use, video and gaming with dedicated video card.
