A Brief History of Computers

The word ‘computer‘ originally implied a person, who, under instructions from a mathematician, performed mechanical calculations. Mechanical calculating devices such as the abacus were often put to use to aid this process.

At the end of the Middle Ages, mathematics and engineering in Europe received a considerable boost, thus leading to the invention of numerous mechanical calculating devices. The technology for clockwork was developed by the early 17th century. The period between the early 19th century and early 20th century saw the development of a number of technologies which would be vital for the development of the digital computer later on. Some examples are the punched card and the valve. Charles Babbage was the first person to design a fully programmable computer as early as 1837. However, he was unable to actually construct his computer due to a variety of reasons.

Analog computers were increasingly used in the first half of the 20th century for a number of scientific computing needs. However, they became obsolete after the development of the digital computer.

The first digital computer was the Atanasoff Berry Computer . It used a binary system of arithmetic, parallel processing, a separation of memory and computing functions and regenerative memory. Binary math and electronic circuits - both of which are used in today’s computers - were first used in the Atanasoff Berry Computer.

In the 1930’s and 1940’s, newer and more efficient computers were continuously developed. Gradually, they came to possess the key features which are present in modern day computers - digital electronics and flexibility of programming.

Among the more important machines to be developed during this time, the American ENIAC was prominent. It was a general purpose machine, but had an inflexible architecture. Later a far superior technique known as the stored program architecture was developed. It is the foundation from which all modern computers are derived.

Throughout the 1950’s, computer design was primarily valve driven. This was later replaced by transistor-driven design in the 1960’s. Transistor-based computers were smaller, faster and cheaper, and hence commercially viable. Integrated circuit technology, adopted in the 1970’s enabled computer production costs to hit a new low, so that even individuals could afford them. That was the birth of the personal computer, as it is known today.

Inexpensive Radius Server Gives Wireless Networks The Security They Need

Many small businesses have considered connecting computers and other devices to their corporate network via wireless (WiFi) connections, and a brave few have actually done so. Many of these early networks required that wireless devices be carefully placed within the building so that the wireless signal reached all intended recipients. Typically, these networks lacked adequate security features, which left them vulnerable to information and resource theft by unauthorized persons. These two problems have now been largely solved, meaning that it may be time for more small businesses to look into the potential advantages a wireless network can offer.

Wireless Networking Basics

Building a wireless network requires two distinct types of hardware components, wireless access points, and wireless access cards. The wireless access point is a device, which is attached to an existing computer network via a standard Ethernet cable. It has an antenna on it, which allows it to broadcast and receive signals from PCs and other devices. Each device wishing to communicate with the access point needs a wireless access card, which also contains an antenna. The current wireless standard, called 802.11g, allows for up to 54 megabits of data per second to be transmitted between the desired access point and the access card. While not quite as fast as wired networks, which typically run at 100 megabits to 1000 megabits per second, wireless networks offer more flexibility, and can be less expensive to install. This is especially true for older buildings where installing cable can become cost prohibitive.

Cutting Corners

Wireless networks use radio frequency waves to transmit information, and thus they are susceptible to being blocked by walls and other obstructions in a building. These obstructions can cause “dead zones” where the radio waves are unable to reach their intended recipients. Microwave ovens and other radio frequency emitting devices can also wreak havoc on wireless signals. The solution is to place your wireless access points strategically around your building so that interference is minimized. When the distance from a wireless access point to the wireless device is more than a few dozen meters, wireless repeaters can be installed to boost the signal. These repeaters can also be placed so that the wireless signals can be accessible from all corners of the building.

Wireless Network Security Solved

Installing a simple wireless network is pretty straightforward, but installing a secure wireless network can be substantially more difficult. However, an Ann Arbor company called Interlink Networks now offers their LucidLink products, which make installing comprehensive wireless network security a snap. Before LucidLink became available, an organization wishing to lock down their wireless network would need to hire expensive network security consultants to install and manage the wireless portion of the network. LucidLink packages all of this expertise into a software add-on that is so easy to use that even a small company’s office manager can easily take control over who is accessing the company network via wireless. It goes above and beyond simple address authentication (standard with most wireless routers), and implements what is called a RADIUS server. RADIUS servers are what large organizations spend thousands of dollars installing and maintaining in order to secure their large (1000+ node) wireless networks. Until now, installing a RADIUS server was out of the price range for all but the largest companies. In contrast, LucidLink’s product can be purchased for as little as $99 for a 3 user Home Office Edition, $449 for a 10 user version, and goes up to $3995 for a 250 user version.

Summary

While there are still issues with making sure that all areas of a building are covered, the current WiFi standard (802.11g) has a more powerful signal, meaning less emphasis needs to be placed on the locations of attached devices. However, it is still recommended that a professional site survey be done to verify that all required areas of the building can be reached by the wireless signal. Meanwhile, Interlink Networks has finally solved the security problem at a price that is affordable for small and medium sized business.

Network+ Exam Tutorial Network Interface Cards (NICs)

Part of the challenge of passing the Network+ exam is learning about all the different types of hardware a network requires. Today we’ll take a look at a vital part of network connectivity, the Network Interface Card (NIC, pronounced “nick”).

The NIC is the device, or card, that gives the host a physical connection to the network. The NIC is generally an internal device, but one that can be removed and replaced with a different NIC. NICs are considered Physical layer devices and work at Layer 1 of the OSI model.

Most issues involving NICs occur before the device is even added to the network - because the purchaser didn’t do their research. All NICs are not created equal. Some are for Ethernet networks, some for Token Ring, and speed capabilities vary as well. Don’t assume a given vendor’s NIC is going to fit your device and give you the results you want. A quick visit to the vendor’s website and a few minutes looking up NIC specifications can save you a lot of trouble later on.

One more NIC warning - take your time when you’re installing a new NIC. Make sure the device is off, and make sure you’re properly grounded by connecting the grounding strap to your wrist. Otherwise, you can send static electricity into places on the host where it’s only going to cause damage.

Your new NIC should also come with directions on how to download the drivers for that NIC. Drivers sound like something physical, but they’re not. Drivers are simply software files that are needed on the host in order for the NIC to work correctly. Vendors used to include drivers on CDs with their NICs, but the trend now is to include instructions on where to download the drivers from the vendor website.

That does lend itself to an occasional Catch-22: “If I don’t have this device on the Net yet, how can I download the drivers?” If the host has no network connectivity, you may need to download the drivers to a host that does, copy the files to CD, and then install the drivers from CD.

You’ll see two different lights on a typical NIC, one green and one amber. Depending on whether the host has network connectivity or not, the lights will be solid, flashing, or out. Sometimes flashing is good, sometimes it’s not! Here’s a guide to the colors you’ll see on a NIC:

A solid green light indicates connectivity is present. This link light is generally either green or off. Green is good, off is not! That light should stay a solid green. If you see it flashing green, that’s a sign of intermittent connectivity, which is a fancy way of saying “one minute the PC is on the network, the next minute it’s not”. Most likely, either the NIC or the cable connected to the NIC is going bad. With the green light, flashing is not desirable.

Flashing amber lights indicate collisions. You’ll see this flash occasionally even on a healthy network, but you don’t want to see it flash so often that it looks like a solid amber light!

If you have an Internet connection at home, you can see these lights in action for yourself. The green and amber lights will be right next to where the cable from your modem connects to your PC.

On occasion, you’ll have a PC that loses connectivity to the network. I advise you to always start network troubleshooting at the Physical layer of the OSI model, and that means checking both the NIC and the cable connected to it. I personally would swap the cable out first, since they seem to go bad more often than NICs, but that’s up to you. If you swap NICs and you still can’t get the PC on the network, try putting a new cable in.

Cisco CCNP BSCI Exam Tutorial The Passive Interface Command And OSPF

To pass the BSCI exam and become a CCNP, you have to be aware of the proper use of passive interfaces. You learned about passive interfaces in your CCNA studies, but here we’ll review the basic concept and clear up one misconception regarding passive interfaces and OSPF.

Configuring an interface as passive will still allow the interface to receive routing updates, but the interface will no longer transmit them. While the command itself would make you think this command will be applied at the interface level, that is not the case. Below, we’ll configure ethernet0 as a RIP passive interface.

R1(config)#router rip

R1(config-router)#passive-interface ethernet0

Ethernet0 will no longer send RIP routing updates, but will accept them.

The passive interface concept is clear enough with RIP, IGRP, and EIGRP - all protocols that send routing update packets. But OSPF doesn’t send routing update packets - OSPF sends link state advertisements. It’s the inability of the passive interface command to stop LSAs that lead many to think that passive interfaces cannot be used with OSPF.

Even though OSPF does not sent “routing updates” in the form that RIP, IGRP, and EIGRP do, you can still configure an OSPF-enabled interface as passive in order to prevent OSPF traffic from exiting or entering that interface. No OSPF adjacency can be formed if one of the interfaces involved is a passive interface, and if you configure an OSPF-enabled interface as passive where an adjacency already exists, the adjacency will drop almost immediately.

Let’s see that in action. R1 and R2 have an existing OSPF adjacency over their Ethernet interfaces. In an effort to reduce routing traffic, R1’s e0 interface is configured as passive. The adjacency drops right away.

R1(config)#router ospf 1

R1(config-router)#passive-interface ethernet0

18:31:11: %OSPF-5-ADJCHG: Process 1, Nbr 2.2.2.2 on Ethernet0 from FULL to DOWN, Neighbor Down: Interface down or detached

Knowing how to use the passive interface command is a vital part of being a CCNP, and of being a master networker. Good luck to you in both of these pursuits!

About The Author
Jelaine Macaraeg
I like to read anything that contains words in the old English form, though I can’t understand it. You know, the King James Version of the Bible with words like thou, thy, thine, wilst, etc. The words used are different. The construction of the sentence is different, too, which makes sentences sound artistic. I also like gothic metal, a music genre, because most of the lyrics contain such words. It is not only the words that fascinate me; it’s the hidden meaning it contains. It’s like an abstract painting; you don’t get the real picture until you see through it.

Wireless Security Basics

Wireless networks using 802.11 have made it simple to connect multiple devices to your home network.This can also make your data availiable anywhere, even outside your home.To set this up all you need is a broadband connection connected to a wireless router or a WAP Wireless Access Point. Your home computers should have wireless access cards installed or if your using a laptop a PCMCIA wireless card. Intel Centrino is great for wireless, I personally use it. I like the fact that I did not have to purchase additional hardware.

When you set up your wireless router or WAP your signal is broadcast. This broadcast usually goes further than your home or business. People like to drive around finding unsecured wireless access points. This is known as Wardriving, some hackers even mark spots on the sidewalk to let other hackers know your home or business is offering free Internet service, or worse yet access to your data.This is not to scare you but make you aware.

Diasble broadcasting so people cannot you your wireless network.

Your routers come with pre-configured system ID’s its called a SSID or Service Set Identifier, its very simple to locate this information on the Internet for default SSID’s I recommend changing this to something hard to guess.
Use alphanumeric’s to make it even harder to guess.

Use encryption to protect your network. WEP or Wireless Encryption Protocol is not secure, I have cracked my own network with a Linux machine running Kismet. WEP’s keylength is only 40 bits, once you collect enough data from packets its only a matter of time for a determined cracker.Instead use WPA which is WI-Fi protected access. This is more secure.

Configure your router to block incoming outgoing traffic you do not use. Consider blocking Port 23 Telnet and Even FTP.

Router manafacturers have default passwords which I find many home users do not change. CHANGE THEM!

Invest in a software firewall and keep your system up to date. In the month of October 2005 there have been several
security flaws listed by Microsoft. Keep Informed.

5 Reasons to Choose Wireless Networking

Many consider wireless as one of the greatest inventions in the history of mankind. Some would even compare it to sliced bread. For them, wiring up a network is just as easy as slicing one’s bread.

The biggest benefit of wireless is that it makes things simpler. You’re not bound by wires to connect your computers at home or at the office. The computers are connected to the network with the use of wireless technology using radio signals.

However, some ask, “Why is there a need for a wireless network?” The following are some good reasons:

Internet Access Sharing

Wireless offers an affordable and easy means to share internet connection with multiple PCs. This usually will not require more than one modem. Also, you can add additional computers to your network by simply plugging in the wireless card and switching them on. Then, they too can have an internet connection.

Sharing Printers and Files

Wireless networks also offer easy file access regardless of which part of the house you are in. It allows easy transfer of the files between your laptops and desktops.

Always Connected

One reason for broadband today is that, you can have an always on connection to the internet. And wireless networks complement this fact. Wireless network technology runs at speeds far greater than broadband internet access easily connecting multiple computers to the internet simultaneously.

Wires? Set them aside

This would be the most important reason to change your old network to wireless. We all know, wires are inconvenient, dangerous and ugly.

Wireless means no more wires. There will be no spaghetti on your floors and corners anymore. This does not only improve the security of your house, it also lessens the danger of tripping or fire.

Play Internet and LAN Games

Wireless LANs allow your entire family is to play a game together without needing to bring your computers closer together. You could also invite other opponents such as your friends and ask them to bring their own PCs. With the wireless network connected to your PS2 or Xbox, playing an online game goes to a whole new level.

History of the Computer; the Emergence of Electronics

The history of the computer inevitably includes the development of electronics, we look at the explosive (!) growth of electronics in the late 1930s and early 1940s.

If anything could be said in favor of war, it may be that it speeds up the development of technology. Of course much of that technology is employed in killing people and destroying infrastructure, but there are also things which could be considered beneficial.

Electronics was around in the early part of the 20th Century, wireless, or radio, was in its infancy at the time of the first world war. Radio broadcasting came into prominence in the ’20s and 30’s, Television started in the ’30’s.

The second world war, from 1939 in Europe, and a couple of years later involving the USA, ended in 1945.
Radar (Radio Aid To Detection And Ranging) was developed from early experiments, just prior to the war, in Britain and Germany. There was rapid development in the field, and, by the end of the war, Radar was being used in several fields.

Aircraft Navigation - Using ground transmitters in sets of 3, widely spaced, to give an aircraft using a receiver a method of pinpointing its position. This is a similar system to that used in gps today, substituting satellites for the ground stations.

Targeting - A beam was transmitted from a Radar station in England so that it intercepted a target in Germany. An aircraft could fly along the beam, guided by signals, dots or dashes, if it strayed off the beam, left or right. Known as flying on the beam.

Interception - a series of ground stations around the South-East coast of England, feeding into a central control room, where their tracks could be displayed, significantly assisted in the Battle of Britain (1940).

Airborne Interception (AI) - Developed towards the end of the war, used a Tranceiver (transmitter/receiver) in a night fighter to find a target in the dark, or bad weather, and track it to within firing range.

Beacon - A tranceiver was located at the end of a runway so that ground staff could guide a returning aircraft to land in bad weather, this became more and more sophisticated, developing into GCA or Ground Controlled Approach.

Shipping - radar equipped vessels could track other vessels in darkness or fog, whether peacefully or aggressively.

Many other sytems were developed or initiated in that 6 year period. Knowledge of electronics, and what it could be used for vastly increased. In parallel with the development of radar, other fields of electronics were also advancing, under pressure from the requirement to improve the technology.

Long range guns on ships or in the field needed to be aimed accurately. The calculations required in ballistics to aim a gun so that you can hit the target, or aim a V2 rocket so that it hits London from continental Europe, are phenomenal.

This, then was the scene at the end of the war. We knew how to tackle large calculations with speed, and we had developed a new concept in electronics:-
Pulse Technology. This is so called because radar uses short pulses of high energy, for two main reasons.

  1. The pulses can be coded. For example, in the Navigation example we looked at, 3 ground stations transmit a signal whose source needs to be identified. One transmitter could transmit a series of single pulses spaced say 10 milliseconds. A second could transmit a pair of pulses at 10 millisecond spacing, and the third 3 pulses. A chart would tell the navigator where the pulse sets were transmitted from, and the distances obtained from the radar set used to locate the position on the chart.
  2. The power, or strength, of the signal. A continuous radio signal, like a radio broadcast, takes a given amount of power. However, a 1 millisecond pulse every 10 milliseconds, uses only one tenth of the power, on average. So a radar transmitter can have a much greater range for the same power. This is is especially important in a primary (transmit and receive) radar system, where we must detect the reflection of the signal we transmit. Likewise a secondary (receive) radar system, for example the navigation system above, will have a bigger range.

Next we will look at how early computers were now possible due to these developments.

4 Tips to Choose Suitable Wireless Router

If you plan to buy a wireless router, check out these 4 tips on how to choose a suitable one. It’s not so easy to decide as there are many choices out there. Basically wireless router is used to route the network traffic between your network and Internet. Hopefully these tips would help you to make good decision.

Check What Wireless Standard you Need

There are many wireless routers supporting different wireless standard, such as 802.11a, 802.11b, 802.11g and 802.11n (draft n), so which standard should you use?

The most popular and mature standard is 802.11g but the latest is 802.11n (draft n), however I would advise to choose the one with 802.11g standard if possible.

802.11g can support bandwidth up to 55Mbps in the 2.4GHz band. It’s compatible with 802.11b products because they both use the same radio frequency. That means 802.11g wireless router will be able to talk to 80.11b wireless adapter. The only problem of 802.11b/g is its interference with other electronic devices that utilize same 2.4GHz radio frequency and this will affect the wireless signal strength.

Then how about 802.11b? Since 802.11g is backward compatible with 802.11g, so I don’t recommend you to use 802.11b product. 802.11a wireless router is not so popular and normally used by business users, so you can forget about it.

As for the router with 802.11n (draft n) standard, it’s still new and the standard is yet to be finalized by IEEE. The expected speed is 10 times faster than 802.11g and the coverage is much wider. If you plan to buy it, be prepare to pay more as the price is expensive.

Compatibility with Other Wireless Devices

Think about the compatibility with wireless adapter, access point or other wireless devices when you choose the router. That’s no point you bought an 802.11g wireless router when other wireless devices are 802.11b aware only.

Always take into accounts of how do you plan to deploy the wireless network, what wireless devices you have and what others you plan to buy when choosing the wireless router.

Wireless Encryption Support

You must always enable encryption on your wireless router, so choose the router with at least WAP encryption. The best you can choose is the one with WPA2 encryption support. Having encryption in your wireless network would allow authorized users with correct encryption key to join the network. It would also avoid your network bandwidth from stealing by neighbor or strangers.

Don’t use WEP encryption on your router if you have better choices, this type of encryption is easily to be hacked by using hacking tool that freely available on Internet.

Other Security Features on Wireless Router

Look for the router that provides firewall feature! This will add an additional layer of protection to your network. If you manage to get the one with stateful inspection support, that would be the best. Stateful inspection firewall will inspect every state of the connections providing better capabilities to drop the malicious traffic.

Check also about the URL, IP and MAC address filtering features. These mentioned security features should be common nowadays, but just check about it to make sure the features are there.

That’s all for the tips, it’s time to go to get your wireless router. Have fun! :o)

Automatic CD Copiers

Automated CD copiers provide hands-free operation and are available as PC-connected or stand-alone models. They are equipped with a robot arm that can load and unload CDs. These CD copiers are actually a combination of many CD copiers - as many as 16. This allows a large number of CDs, from 100 to 1000, to be copied at a time. CDs that cannot be copied or have some problem are automatically rejected at the end of the process.

Traditional CD copiers are operated manually. The CD copier uses a burning software application that is installed on the computer. CD copiers can usually burn only one copy at a time. After one CD is copied, the user has to manually open the drive shutter (or press a button provided for that purpose) and replace it with another blank CD for copying. This makes copying CDs with a manual PC copier a slow process.

Automated CD copiers make the burning process much quicker. These have an input spindle and an output spindle. Blank CDs are placed in a stack on the input spindle. A robotic arm picks up blank CDs from the input spindle, one at a time, and sends them into the drive for copying. When the burning process is over, the CD is automatically placed onto the output spindle. This is a hands-free process, but it takes a long time to complete the process.

These automated CD copiers are ideal because the CD copier can be left running overnight or a weekend. A large number of CD or DVD discs can be stacked on the spindle, and the machine can be left to run until the job is complete. Some machines can also be networked, allowing multiple users to have access to the CD copiers.

These Automated CD copiers thus make the task of copying several CDs easier. It also brings precision and efficiency to the entire process.

CD Copiers provides detailed information on CD copiers, CD DVD copiers, CD copier software, CD copier downloads and more. CD Copiers is affiliated with Business Card CD Duplications.
