A Quick Introduction to Computer Network Servers – Part II

In the previous section, we presented an introduction to computer networking and network servers which are often part of the organizational network setup. However, usually there are several types of the network server which may be used for more productivity and purposes within an organization such as the following.

1. Web/Proxy Server:

Web server and proxy server are different yet relevant and dependent servers on each other. Their main role is to respect the HTTP prompts regarding web pages.

2. Database Server:

When you operating your network at reasonable large scale, you need a database server where you will maintain the record of your employees, customers, and so on... A particular database is created and maintained whenever a new member is welcomed at a network.

These are the most common and important network servers, although there are some other servers in addition too, namely these are video server, storage server, time server, access server and fax server. Well, don't get in trouble by going through these names as Computer Networking expertise can get you of your desire network setup.

Basics About Star Computer Networking Topology - Part-II

Whenever, a subordinate in a group willing to have communication with a node lied in a other group, so initially the sender request will be go through its associated group to central hub, thereafter hub will re-transmit the signals towards the group where the correspondent recipient lying. The advantage of to opt for an extended star topology is that it covers up a little bit of cabling cost in a traditional star topology, but at the same time it increases a bit of risk as well for the reason that if a sub-central device is got failed, all the associated subordinates will also be cut off from the network setup. To figure it out you need to have contact with an IT Support Los Angeles to help you out whatever problem you facing in context with computer networking. Though, star topology is one of the reliable and mostly used network architecture all over the globe.

Since you have got sufficient information regarding star topology and extended star topology, now you should justified your requirements to come up with a solution which topology will going to suit the best. If you are unable in making decision or justifying things all around you should make advice with an IT Consulting Los Angeles Firm to get you whatever accord you the best. Overall concept will be summarized in such wordings that a simplified traditional star computer networking topology is all alone match up with the requirements where a network setup is required for a small business or in a small building, while on the other side of the coin, extended star topology will do best and suits good for larger span of site or for a business operating at a larger scale.

Basics About Star Computer Networking Topology - Part-I

Computer Networking, a technological arena where bunch of computer systems and resources are get connected for the ultimate end to provide a stage of communication and sharing. While Topology a set of rules and guidelines how these bunch of computer systems and devices will be attached with each other and will take part in communication. There are many set of rules and guidelines are introduced to established such and other sorts of network setup, but in spite of this we will merely get bonding with star computer networking topology for this unique moment. In a star topology, each of the network node has a direct dedicated connection with the central device named Hub. This dedicated connection makes the star topology really reliable for the reason if the a certain link is get damaged so it will merely effect the concerned node rather the entire network setup.

Considering the prior tribute tale to star topology, we can judge that it would be an expensive topology, no doubt, for the reason that it requires each node to have a direct connection with the central hub for access. But things are not going in the same way, in this technological pace, we are stepping forward to the stage to get most out of a simple thing. The traditional star topology is customized to get the same level of output, even better than that, with less investment or input you could also say. The newly customized star topology is termed as Extended Star Topology, where there groups are created and maintained. Each group has a direct connection with the hub via a dedicated link while each group has got its own subordinates directly attached with it and indirectly connected with the central hub.

General Overview About Ring Topology - Part-II

Regardless of the statements tributes priorly, now just get step in into the spot where we will get to know how the data packets are transferred over the Ring Computer Networking Topology. Once a sender initiated a request send packets over network, it will be passed to the adjacent node firstly, if the header information quoted along with the token matches with the adjacent node, it will accept it to continue with the transmission, else it will retransmit the request to its own adjacent in the network for matching up the IP addresses and in this way the process moves on in a ring style. Erstwhile the desired recipient gets the request from its own adjacent node and IP addresses are matched up and justified that the request is meant merely of it, it will then issue an acknowledge to the sender to initiate as well as set free the token over the network so that other nodes could also use it waiting in the queue for its turn.

All such kinds of activities are maintained and handled by an agent named as Multi Access Unit – MAU for a short. It has got similar job like a traditional hug have in a star topology, but the difference comes in context of how data packets are treated over the network topology. Wherever we are concerned with Hub, it simply broadcast signals to all stations attached with it, while an MAU in a ring topology creates a logical ring by transmitting request neighbor wise until and unless the end recipient gets it. Considering the entire storyline you should get to know and make sure in addition too that either ring topology is suitable with your business or requirements or not. However, an IT Consulting Los Angeles firm will help you out to the best level and will guide you what sorts of topology and implementation will give you the best output.

General Overview About Ring Topology - Part-I

Topology, which is the layout of how computer systems and other networking devices are connected together to create a vibe of communication and sharing between users. There are many types of topologies could be adopted to initiate and maintain such environment, for instance, star, bus, ring, mess, and tree topology.

For the special moment, I will focus on Ring Topology, how it works and its merits and demerits. In the most fundamental aspect it works on a factor known as token, and for this reason it is also known as Token Ring Network. A token is a kind of permission a node would have in a ring topology to transmit data packets. Whenever a node intended to transmit packets over network setup, it needs to have a token, once it is gifted with the token, it can merely then send packets to the suggested recipient. During the time preceding as it get a token, it attaches the recipient information along with it, when recipient receives the packets, it acknowledge the sender with respect to the request of incoming packets. This acknowledgement trigger sender to set the token free all over the network for rest of the nodes so that it can also get its turn for sending data packets. It was all about how a node get an opportunity to transfer its data packets to its desired computer networking recipient.

Computer Network Setup Classification – Part II

As, different devices and peripherals constitute network setup can also be developed without using all above mentioned physical tools and mediums, and this could be done by opting for Wireless technology that works on radio waves or infrared in addition. Computer networking Los Angeles suggesting two broad categories for computer network. However, following is the second classification of the networking in major.

Wireless System.

Apart from physical communication channels, network setup can also be done using wireless technologies which includes many and effective sources. In essence, wireless technologies includes terrestrial microwave, satellites, Cellular technology, and infrared media enlisting too. Computer Networking Los Angeles is not merely restricted to wired technologies but it also serves you best using wireless technologies to build your computer network.

Though, various other configurations and classification may exist but primarily there can be either wired or wireless network setups.

Computer Network Setup Classification – Part I

Computer networks can be categorized considering the hardware and software being used to interconnect the distinctive devices in a network setup, for instance fiber optic cable, wireless source, or other power line communication. A traditional LAN or local Ethernet used many level of measurements and communication medium that make possible the connection and communication between various devices like hubs, switches, bridges, or routers in addition with too. However, in the following, classifications are explained.

Wired System:

The interconnection between networking devices can be formed via many wired communication media like twisted pair cable, coaxial cable and most efficient fiber optics. Every of these physical media has its own characteristics and usages. Twisted pair cable is mostly used in telecommunication sector, easy to use and install. It has multiple variations in it for instance Unshielded Twisted Pair (UTP) and Shielded Twisted Pair (STP) which are further categorized into more variation. While on the side of the coin, in essence, coaxial cables are used in LAN and personal established network setup. At last but not the least, Fiber Optics is also wired communication media yet its totally different from the other two media mentioned above passage as it uses glass through which electrical signals passes on. Computer Networking Los Angeles providing complete sets of guidelines to opt for the right one for your network.

Fix Your Computer Network Issues

A computer network is one of the best approach to share resources with one another in a network. Most of the time a home based network setup is developed just to share internet connection and data. While if it comes to a business whether operating at small or large scale, they opt for a computer network for the sake of sharing of frequently use resources including printer, scanner, and internet connection itself. But life is not that much tension free, problems are occurs, so is the case with your computer network, it could get you in uncomfortable zone by popping up annoying issues. But we live in highly technological world, there is a cure for every disease, computer networking Los Angeles is all the way eager to help you and to figure out the bugs screwing you up frequently.

Well, its not the end yet, Computer Networking Los Angeles is gifting you up some handy tips and tricks to play around with your local network. The very first thing before initiating a network setup you must give a unique name to your system and common Work-group name that would be shared by your other fellows willing to establish connection with your system. Now to name your computer is quite easy as you will be required to go to your computer properties, and there you will get Computer Name box, name it uniquely as it will merely belongs to you, and assign a mutual name in work-group box that will also be adopted by others in your computer network. Now you are just system restart away to have your own personal network setup.

How Computer Networking Issues Occur in Businesses?

It is mostly observed that miscommunication leads to failure of services and equipments that are being used by your employees either because of informality of IT Support team or some time because of non-serious behavior. It is also form because of regular change in management department and of-course the lack of communication between the equipment operators and IT technicians.

To avoid delay in your on-going project or any kind of computer network related issue that create some destruction in the flow of work then you need to properly disclose the rules and obligations, so every one can follow up them when they find any thing inappropriate. The IT staff must check up all the machines, devices and equipments regularly at the end of every weekend and fix the errors if there is any. Softwares must be updated regularly, specially the anti-virus and firewall stuff to make the network setup fully secured from any kind of viruses, unauthorized users, bots, Trojans and Mal-ware etc.

Well if you are running a new business specially a small one then you must not go for hiring in-house IT staff for your Network Setup and related tasks. Opting a good off-shore company not only saves the extra cost of in-house members but also gives you best results as they have well experienced member who had worked for different type of businesses. You can also hire off-shore companies to look after your computer network VIA remote network access to maintain its working capabilities.

Some Basic differences between Wireless and Wired Network setup (Part B)

Previously I had discussed about the wired and wireless technology being used in Computer Networking and also about some factors that prefer wireless technology over wired. Now In this post that why I said earlier that “in some aspects we still wish to have old technology”. However wired technology is being updated regularly but in IT field it is consider as an old technology.

Undoubtly wireless technology is quite efficient for limited are networking but when we need to build a huge network setup of numerous computers assembled in different rooms and floors than the most reliable equipments that support you all the time are wired equipments. Wired networks fall into different categories depend upon the situation and adopted the one that suits the best.

Wireless technology can also be applicable in multiple rooms but its cost go way up when you try to make a perfect network setup on the other hand you can go for wired technologies, both will work in same order but the cost of wired network is quite good for new and small business entities.   

Some Basic differences between Wireless and Wired Network setup (part A)

We all know that the latest technologies are more reliable and convenient as the are updated with the latest user demands and queries but it’s also a factor that some time they do feel that the old technology is better in some specific aspects. It’s a natural fact that human also want more and more.

Well, wired Network Setup is the first/old technology that is still being in use for connecting more than on computers but now days it is over taken by wireless technology. Though wireless technology is quite effective but it is getting in to businesses pretty slowly and most of the businesses still prefer to have wired networks. There are some specific points that make these both type of networks to be ahead of each other.

Wireless technology is taking over wired technology because of its nature, businesses that are established within a hall prefer to install wireless network to get connected with each other. As the efficiency of wireless technology is limited to some specific extent of area and also the signals get weaker and weaker when you try to access it from other side of the wall/room. so if you are going to install a Computer Networking for your business or within your room then wireless technology is best opt to go for as it is mobile in access and you don't need to embed nails and ducts on your walls or to take an extra care of wires from getting crack/damage.

How to Maintain The Efficiency Of Your PC/Network Setup (part B)

To maintain the efficiency of a network setup we had discussed about three main steps Anti-virus, Proper Shutdown Procedure and backup. While carrying on this topic I will put some light on some other factors which will surely help you to work in a safer computerized environment. 

Some time the technical team ignores the backup plan for the failure of electricity, either because of non-habitual demand or some time by mistake. It is your duty to put your PC's or at-least the main/server machines on UPS so if there is a failure of electricity it will not effect the working of them. Its importance is already mentioned in previous post.

Regular Fragmentation and Check Disk run will help you to remove hard disk problems and also it will assist you with the speed of your PC. To Complete fragmentation you need more than 20% space in your drives to perform fragmentation and also if you have a hard disk almost filled up in every partition then it will surely decrease the performance of your operating system.

You need a network monitor to look after your network 24x7, in-case if any one try to break in to your network he/she would be able to block them or catch them before they do any thing in to your business Computer Networking.

These are some of the basic steps which not only make your machine run at there maximum but also it will help you to work in a safe environment.
