SAMSUNG Galaxy S5

There was talk of an entire new plan dialect for the Galaxy S5 with some trusting that Samsung might split far from the comparable styling of the Galaxy S3 and S4.

This hasn't happened all things considered. Configuration astute, well you can't call the Samsung Galaxy S5 terrible, since Samsung does know how to assemble a telephone well.

Anyhow in the meantime its the same tired story on the configuration front: taking a few components from the antecedent, including a few bits from the current Note and calling everything new.

The "metal" encompass is practically indistinguishable to the Note 3, to the point we were searching for a S Pen to begin jabbing out in the active audit. Be that as it may the back is the fundamental change and we might head off as far to say that it is exquisite.

No more sparkly plastic or funny endeavors to make it resemble a cowhide journal – while it is still plastic, its a great deal more grippable and feels a ton, part more pleasant in the han

Transparent Caching

the browsers should be configured explicitly to use a proxy server. this is not a headache anymore instructing each and every client to make proxy settings. Transparent caching is very handy in such cases. transparent caches are simple and they can be easily used in a network and do not require explicit coordination with other caches. Transparent caching in context of HTTP proxy caches means the transparent hijacking of the port 80, which is the default HTTP port. the cache hijacks the port 80 traffic whenever the client tries to request to the remote servers. the client does not have to configure his/her browser. instead squid transparently picks up requests and responses to the client. squid cache/proxy server acts as transparently caching servers and fulfils the clients requests of web objects, if available locally hence making efficient web browsing.

Web Caching

web caching refers to storing locally the once referenced web objects, should any future request come for that object, it is checked for in local store and if present there it is retrieved directly from the local store instead from the original server. It saves time, bandwidth and of course money. Web caching can be done at end users desktop or on dedicated cache server. Most of the present day browsers have support for caching to some extent though they are not of high performance and limited to a computer only. the most effective way to implement cache is by service provider. they can deploy a dedicated server and high performance web caching software. Wherever caching is done the goal is the same. It is better if ISPs cache web objects so that frequently referenced sites could be serve locally instead of downloading every time from the original servers. This increases throughput dramatically. the above discussions suggests that given sufficient storage, whole internet could be cached. However this is not true, Information is dynamic in nature and so is the web. If we cache everything we end up serving stale objects to the clients. this is worse than having slow access. there are methods to ensure the freshness of an object stored in a cache.

What is FTP ?

The FTP(File Transfer Protocol) utility program is commanly used for copying files to and from other computers. FTP is a general protocol that works on unix system as well as a variety of other (non unix) systems. FTP is basically used to promote sharing of files (computer programs and/or data), to encourage indirect or implicit(via programs) use of remote computers, to shield a user from variations in file storage systems among hosts, and to transfer data reliably and efficiently. FTP though usable direclty by a user at a terminal, is designed mainly for use by programs. FTP is in common use for downloading data and programs and for uploading files such as web sites to or from the servers of the same or different architecture.(such as windows PC,MAC ,etc).

OSPF (Routing Protocol)

For big networks in the internet what we need is a network path which is shorter and best. OSPF is a routing protocol which enables data packets to choose the best path. It is widely popular IGP (Interior Gateway Protocol) which is implemented by most of the major network providers. OSPF stands for open shortest path first, this protocol determines the best path for routing the data traffic. OSPF does routing based on cost calculation, the path with lowest cost always gets the priority. Consider the example below in this network the lowest cost is 10 hence the packet chooses the path with lowest cost to reach the destination.

In the OSPF, whole network (single autonomous system) is divided into smaller areas so that network is optimized. OSPF uses hello packets at first to calculate the neighbors and then the routing table is updated. For smaller network (typically up to 10 routers) single area is sufficient, but for large networks single area is not sufficient. For larger networks OSPF requires multiple areas so that routing information is limited and the routers processing capacity and memory is optimized.

OSPF uses LSA (Link state Advertisement) packets to update the routing table. There are different types of LSA packets and based on these types network is designed. Different types of area for example core area and other area requires different types of routing information. Hence to distinguish these types of network routing information is either limited or maximized.

What Is IP Address

What IS IP Address?
An IP(Internet Protocol) address is an address that is assigned to any computer or media which is connetcted to a computer network. The main concept of an IP address is to name a computer in a network so that it can be easily identified. There are two types of IP addressing that exist in the current world scenario- they are IPV4(Internet Protocol Version 4) and higher version is IPV6(Internet Protocol Version 6). IPV4 is 32 bit addressing mode from which we can address upto 2^32 computers. initially designers thought it would be enough for the world but as the technology is growing so much rapidly and most of the electronic media are IP based hence the need of IP address is growing rapidly hence the 32 bit IP addressing is not enough so now designers have chosen a new addressing scheme which consists of 128 bit addressing mode so we can address upto 2^128 computers. With this new scheme of IP address there wont be scarcity of ip address for long years to come.
