How The Internet Has Evolved Over Time

Many people have heard of the Internet. In fact, according to TechPulse360, over one billion people use the Internet each day. With such an extensive number, it is easy to see exactly how the Internet has expanded over the past thirty years. Few people know the history of the Internet. However, it is easy to notice. Each year computers are getting faster and smaller. Each year, the Internet is getting faster and better. Something that started as a government project is now becoming one of the most commonly used things in the world.

The history of the Internet begins in the year 1973, where it was created by a group of people from ARPANET. ARPANET was a government organisation. Vinton Cerf and Bob Kahn led this group. The project was meant to allow other computer networks to connect and communicate with one another.

In 1976, Dr. Robert M. Metcalfe developed the Ethernet. The Ethernet essentially allowed the coaxial cable to move data faster than normal. This was the first step to developing the LAN networks. In addition, it was the first step to making the Internet faster.

1983 marks the time when every single computer that was connected to the Internet had no choice but to use the TCP/IP protocol. Because of this, 1983 was the year when the use NCP protocol ended.

The National Science Foundation began working on the new T1 lines in the 1980s. By the time they were finished in 1988, traffic began to increase. Because of this increase in traffic, the NSF began working on a second update.

In 1990 the non-profit organisation ANS formulated the idea for a T3 line. It was a 45mpbs line and by 1991, all of the NSF websites were using this new network. In addition, ILEC created ADSL, or Asymmetric Digital Subscriber Line. This type of technology allowed its users to surf the web. ADSL later became DSL.

In 1995, the NSF stopped allowing free direct access to the NSF backbone. This period marks the time when people began to pay for web hosting. NSF allowed four companies to have this direct access. These four companies consequently sold access to the server for fifty dollars a year. This cost did not include .gov and .edu domains.

Broadband was introduced in 2000 as a better alternative to dial-up. The beginning of broadband marked the beginning of the Internet, as we know it today. Because of Broadband, users are able to download music and videos. The Internet became at least ten times faster than dial-up. It is also hard to forget the creation of 802.11b, more commonly known as Wi-Fi. Wireless Internet allowed the use of handheld devices and the ability to take the Internet anywhere that you are.
The evolutionary speed of the Internet has taken us to the next level in communication and its still unknown how far we can really go?

How The Internet Has Developed Over The Years

Dial up internet was where it all started for the masses of people who wanted to get online in the comfort of their own homes. Computers were rarer in times gone by than they are today, when many homes may even own more than one. Dial up internet was amazing at the time, but it was also frustratingly slow. It also meant that you could not use your phone line, and if anyone wanted to call you they would find the line engaged.

Then came the next new thing – broadband internet. This promised to be much faster and more convenient, and indeed it was. Suddenly we all got our phone lines back, as the broadband service came into our homes in a different way. Now we could go back to using our phone whenever we wanted, without tying it up whenever we went online.

Broadband was definitely faster, but developments are still taking place today that have made it faster still. Fibre optic internet is the way of the future, and it is being rolled out across many parts of the country by several companies.

But it doesnt stop there. We used to be limited to using the internet when we were at home, or at another place that had an internet connection. But this has all changed because we now have mobile broadband as well. This is accessible by way of a Broadband Dongle. This unusually named item plugs into a laptop via its USB port and acts as a mobile internet connection. It means we can now go out and about with our laptops and still get online if we should need to.

Needless to say this has made a huge difference to people who work and travel a lot. A Mobile Broadband Dongle is a great way of getting online to answer emails, surf the internet and monitor our websites when we are travelling. Instead of wasting time sitting on a train or at an airport, we can use the internet via a broadband dongle and make the most of the service we get. It means we can be a lot more practical with our time, using it more than we would otherwise.

A mobile broadband dongle would have been unthinkable even a few years ago. But thanks to advances in technology we now have many more ways to connect to the internet. We can even go online via smart phones now, but we still need laptops in many different ways. If you need to have access to the internet for work, no matter where you might be, a dongle could be the answer you have been looking for.

It makes you wonder what will happen next, doesnt it?

Ccnp Certification Bcmsn Exam Tutorial Server Load Balancing (slb)

When you’re working on your BCMSN exam on your way to CCNP certification, you’ll read at length about how Cisco routers and multilayer switches can work to provide router redundancy – but there’s another helpful service, Server Load Balancing, that does the same for servers. While HSRP, VRRP, and CLBP all represent multiple physical routers to hosts as a single virtual router, SLB represents multiple physical servers to hosts as a single virtual server.

In the following example, three physical servers have been placed into the SRB group ServFarm. They’re represented to the hosts as the virtual server 210.1.1.14.

The hosts will seek to communicate with the server at 210.1.1.14, not knowing that they’re actually communicating with the routers in ServFarm. This allows quick cutover if one of the physical servers goes down, and also serves to hide the actual IP addresses of the servers in ServFarm.

The basic operations of SLB involves creating the server farm, followed by creating the virtual server. We’ll first add 210.1.1.11 to the server farm:

MLS(config)# ip slb serverfarm ServFarm

MLS(config-slb-sfarm)# real 210.1.1.11

MLS(config-slb-real)# inservice

The first command creates the server farm, with the real command specifying the IP address of the real server. The inservice command is required by SLB to consider the server as ready to handle the server farm’s workload. The real and inservice commands should be repeated for each server in the server farm.

To create the virtual server:

MLS(config)# ip slb vserver VIRTUAL_SERVER

MLS(config-slb-vserver)# serverfarm ServFarm

MLS(config-slb-vserver)# virtual 210.1.1.14

MLS(config-slb-vserver)# inservice

From the top down, the vserver was named VIRTUAL_SERVER, which represents the server farm ServFarm. The virtual server is assigned the IP address 210.1.1.14, and connections are allowed once the inservice command is applied.

You may also want to control which of your network hosts can connect to the virtual server. If hosts or subnets are named with the client command, those will be the only clients that can connect to the virtual server. Note that this command uses wildcard masks. The following configuration would allow only the hosts on the subnet 210.1.1.0 /24 to connect to the virtual server.

MLS(config-slb-vserver)# client 210.1.1.0 0.0.0.255

SLB is the server end’s answer to HSRP, VRRP, and GLBP – but you still need to know it to become a CCNP! Knowing redundancy strategies and protocols is vital in today’s networks, so make sure you’re comfortable with SLB before taking on the exam.

Why Environment Monitoring Systems are essential in every server room

Information Technology support is not just about setting up your business IT infrastructure and fixing your server incase it collapses. A large chunk of work done by reputable IT consultants involves regular monitoring of your server system to ensure that everything is working as it should. Monitoring servers are extremely important and are central to productivity. Unfortunately, this is one aspect that is often disregarded in terms of facilities management. If your building has a data centre (central server), then it is imperative and essential to install a proper monitoring system that will ensure that conditions in your server room are in proper order.

Environmental threats in your server room can cause more damage than hardware or software problems. These threats include changes in temperature, humidity, the presence of water and so on. One of the most common environmental threats in any server room is heat. Critical rises or drops in temperature can lead to failure of equipment. Also, any amount of water from a faulty sprinkler system to a flash flood or changes in humidity can damage your system. High temperatures, humidity and water can shorten the life of expensive equipment and can cause downtime or even failure of critical network systems.

Failure in equipment means that your business will not be able to run efficiently and effectively for hours on end or even days, until the problem can be fixed or equipment can be replaced. This means a reduction in efficiency and productivity of your company, and of course in expenses incurred. To prevent disasters like this, the use of environment monitoring systems are essential.

By having an environment monitoring system that can relay information about changes in your server room, you can have peace of mind knowing that you are fully aware of what is happening in your server room at all times. Environment monitoring systems are able to detect threatening conditions such as fires, floods, intense temperatures before your equipment is damaged or destroyed by the incorporation of a wide range of sensors. The environment monitoring systems are able to alert users via siren, alarm, beacon, voice call or even by SMS. Systems with cutting edge technology also allow you to manage your server room remotely, and reboot servers and network devices remotely if necessary.

Error C1041724 Mounting Exchange Server Database

Exchange Server databases’ transactions are temporarily stored in transaction log files. At times, you need to remove these files manually, usually when the disk runs out of space or the circular logging is disabled. If you come to such situations, it is recommended to determine that the logs have been committed to database or otherwise will cause problems. The database usually shows Dirty Shutdown state in such cases. However, the other reason for this is that database is corrupt. If it is, you should look for Exchange Recovery solutions.

You can take the following situation when you try to mount an Exchange Server database. In an attempt of mounting the database, you might receive an error as below:

An internal processing error has occurred. Try restarting the Exchange System Manager or the Microsoft Exchange Information Store service, or both.

ID no: c1041724
Exchange System Manager

The mount operation fails after you receive this error message.

Cause

Error c1041724 can be encountered if you have run eseutil /p repair utility on the affected database. At this point if Eseutil log files remain intact and are not removed, the database can fail to start with the above error.

Solution

To isolate the issue, you need to proceed as follows:

1.You need to first check if eseutil /p command was run. To do so, you should run eseutil /mh command for pub1.edb and priv1.edb and check the repair count value. If it is other than ‘0’, this shows that the command was run.
2.From the previous step, you also need to check for the database consistency. If it exists in Clean Shutdown state, which shows that the log files have been committed, you can safely remove the log files from Exchange Server folder, Mdbdata folder to a backup folder and mount the database.
3.If the database shows ‘Dirty Shutdown’ state, it may be because either all the log files have not been committed yet or the database is corrupt. You can wait for sometime to determine if uncommitted transactions is the case. If not, the database is corrupt that you need to restore from backup or by performing soft recovery.

In cases when database remains corrupted with no access to a suitable backup, you can use third-party Exchange Server Recovery utilities. These special applications allow safe extraction of user mailboxes without any modification to the original content. Exchange Recovery utilities provide you interactive design plus impressive features to experience.

Stellar Phoenix Mailbox Exchange Recovery is a complete tool that repairs Exchange database repair systematically. It is a safe and powerful Exchange Server Recovery tool that supports Exchange Server 5.5, 2000 and 2003. The tool can restore mailboxes in individual .pst files, which can be directly accessed in Outlook. The software is enriched with a realistic approach to repair corrupted EDB file in each instance.

Shall We Ban Internet Slang In News And Formal Documents

In the modern society, internet has played a more and more important role in our daily life. Consequently, many internet slang terms such as PK hold gelivable become popular almost overnight. Some of them are even used frequently by some media such as in the newspapers, magazines. Some editors of the textbooks even employ them in the textbooks. Opinions of the employment of internet slang terms in media or formal documents vary from person to person. Some people assume that we should ban the use of internet slang terms in formal or official documents as they may mislead the young generation while others believe that it is not necessary to do this because it is an inevitable tendency to use the internet slangs. Supporters for the adoption of internet slang terms also account for such phenomenon because they think anything that exists is reasonable. However, for the healthy development of language usage, internet slang should be banned.
Firstly, repeated use of internet slang will mislead the youngsters. Nowadays, with the consummation of internet facilities, nearly everyone has an access to it. Among them, teens form a large group of netizens. Therefore, they may come across many internet slang terms. To their surprise, some terms are not in conformity with their original meanings. As a result, they are not sure which meaning to choose when they want to express their ideas.
Secondly, some internet slang terms have derogatory sense and are often used to scold people. Once teens learn such meanings, they will use them in their daily life and develop a bad habit in using language. Whats worse, they will consider use of these terms as fashionable and may follow the fashion blindly. It will do much harm to their healthy development both mentally and emotionally. Hence the internet slang terms should be banned.
Thirdly, although many items become popular overnight and to use them is even considered as a fashion, fashion will pass by soon. Only those words that can undergo the selection of people as well as test from time can be accumulated into the literature reservoir. In this sense, it is far from enough for us to adopt the slang terms because they have not been tested by the time.
In a word, although the internet slang terms are popular and expressive for a period of time, we still need to think twice before we allow them to enter into the linguistic family.

Resolving Error 501 In Exchange Server

Exchange Server Information Store databases support transaction logging i.e. before committing any data to the database, it is first written to transaction logs. If your database is ever forced to perform recovery, these transaction logs replay and restore the database to a working state. When an Exchange Server Information Store database corrupts, it marks an event indicating the root cause of the issue. You can deduce the problem and thus, take corrective measures to solve it. In cases, when no backup is available to replace the damaged database and ESEUTIL utility also fails to repair, you need to use an effective Microsoft utility that could repair and restore the damaged database.

For an instance, you might receive the below event ID in Application log of Event Viewer:
