The advantages of PKI certification are very varied and numerous hence the growing need for it. This concept mostly applied by the IT security field was known for  authentication, it also has a lot to do with issues of public key pairs.

For PKI to work effectively in your office it is important to understand how helpful it will be to you. Public Key Infrastructure Certificates ensure that there is a more secure system such that decrypting and encrypting is not shared by everyone.

A lot of legalities are involved so you need to understand  PKI very well.

I waited for their device that can be connected via the USB Adapters but I could not wait much. Yesterday I went to their office an bought the device that is connected via the PCMCIA adapter. The device manufacturer is Huawei and the Model of the device is EC360-EV-DO. I had to buy a PCMCIA Adapter first to be able to connect the Device with. I will mention the prices at the end the article.

Lets start with the experience. As mentioned on PTCL Website the downloading and uploading speed would be 300-700 KBPS and 200-400 KBPS respectively but…what I experienced was a little shocking. The downloading speed won’t cross 200 KBPS and Uploading speed 50 KBPS. I don’t say that this is the actual speed because I am using the device in my room and weather has been cloudy for couple of days now in Islamabad so, that could be the reason. The speed may increase if I use it on my laptop in open environment but that is not possible. The PCMCIA adapter is not available on my laptop and it is not available in most of the new laptops. So, if you are buying a laptop to use the current device, make sure it has a PCMCIA slot.

The device comes with a Manual, Driver CD ROM, and a headset…You must be thinking why a headset. I thought the same and called up customer support center. She told me that a number is provided with your device which you can use but the Voice Port is not open yet. According to her, it will be open very soon. There is a slot for the headset pin on the device. That’s good, now you can have a PTCL number with you if you have this device. I also asked her about the device for USB Adapter and she told me that it is expected later this month.

Details

Manufacturer: Huawei Technologies Co., LTD

Model: EC360-EV-DO.

Price & Charges

PCMCIA Adapter: 2300 PKR

Broadband ‘On the Go’ Device: 4000 PKR

Per month Charges: 2000 PKR

The subnet mask offers you all the information that you need to calculate the network and host portions of the address with great ease. With the subnet mask you can calculate whether the IP addresses are in a similar subnet.

The subnets are necessary for the IP network communications to carry on. The network devices use the IP addresses and a defined subnet mask to determine if the host is on a remote subnet or local subnet.

Subnet Mask

It makes it easy to identify the number of hosts capable of being included on the same subnet.

The sound and voice that human beings hear is in analogue form and has to be converted to digital to make it possible to transmit it over the internet. The sound or voice has to be converted back to analogue once it reaches the receiving end so that it can be heard.

VoIP Codec

There are various ways that the decoding and encoding can be done but the majority of them use compression. This method ensures that the bandwidths are reduced. If the compression is heavy, there is usually a delay in the conversation because it takes time. It is possible to find a VoIP codec that will take a minimum amount of time.
