Nowadays, for a regular person, purchasing electronic equipment has turned into a bad dream. As soon we open any internet shopping entry and enter our catchphrases, we are welcomed with excessively numerous outcomes coordinating our inquiry terms. In the event that you too don’t have much enthusiasm for electronic or PC equipment, then it is likely that you are puzzled with the quantity of decisions you have.
One such piece of equipment is the network interface card. This card can be used to connect a computer to a hub, a modem, a router, etc. These network devices may in turn connect the computer to a PAN, LAN, MAN, WAN or the Internet. Before we turn to the points to consider before buying one, let’s first try to understand the basic types of NICs.
Types of NIC
Based on the type of medium that network interface controllers use for communication within a network, they are broadly classified into 2 categories:
➥ Ethernet Network Adapter: Ethernet is a wired networking standard (IEEE 802.3) for network communication. If you are a fan of a hard-wired network adapter, then this is the way to go.
Powerline systems administration is one of best techniques to change over any home into a keen home. There are no deadspots in a powerline arrange unless your room doesn’t have a power attachment. Powerline systems transmit information through the current electrical wiring of a structure. Presently, before you set up a powerline organize connector, here is the manner by which it works.
Powerline networking is based on the fundamental concept on OFDM (Orthogonal Frequency Division Multiplexing). The powerline adapter superimposes its high frequency signal composed of user’s data on to lower frequency sine wave signals (50- 60 Hz). Did it ring any bell? The alternating current that we use in our homes has a frequency of 50-60 Hz.
A powerline network adapter is also known as HomePlug. These HomePlugs have rated speeds of 85 Mbps, 200-500 Mbps and 500-1 Gbps for HomePlug v1.0, HomePlug AV, and HomePlug AV2, respectively. Setting up a powerline network adapter is a fairly easy task and is explained in a few simple steps given below.
Just ensure the following things before you begin.
● You need at least 2 adapters to make a powerline network.
Coaxial link connectors are additionally called RF connectors, and are utilized as a part of uses where radio recurrence or RF associations are required. Here’s the way you can approach introducing them at home …
Coaxial cable connectors are also commonly called F connectors, and are used in places where television signals and radio frequency are necessary. F connectors are commonly used for cable and terrestrial television. They are also used as over-the-air cables for satellite television and cable modems. If you are planning to hook a new cable or satellite TV service, you will have to install its cable connectors correctly. Before you learn to do so, buy a coaxial cable RF tester to detect wiring faults and cable connections.
Types of Coaxial Cable Connectors
- UHF connector
- N-type connector
- BNC connector
- TNC connector
- SMA connector
- SMB connector
- SMC connector

- MMCX connector
Coaxial Cable Connector Installation
Installing these connectors is rather simple, but takes a bit of practice.
Prepare the Coax Cable
Get hold of a coax cable and cut it for installation. Now with the help of a utility knife or razor knife, cut off the black outer sheathing of the cable to ½”-¾” size.
In the field of PCs, ring, transport, tree, and star are the names doled out to particular system topologies.
Basically, the term ‘network topology’ refers to the layout pattern of interconnections of various elements of a computer network, like the nodes, links, etc. The concept is further categorized into two types: (i) physical topology, which refers to the physical design of a network, and (ii) logical topology, which focuses on how the data is actually transferred within the network.
The physical topology is further classified into six different types; namely, the point-to-point network, ring network, mesh network, bus network, tree network, and the star network. Of these, the star network in particular is considered very popular owing to its numerous advantages. That is not to say it doesn’t have any disadvantages of its own. It is important to go through the advantages and disadvantages of different network topologies―and not just the star topology alone―to determine which of these is suitable for you.
What is Star Topology?
In this type of network topology, all the nodes are connected individually to one common hub. The transmission stations are connected to the central node in such a manner that the design
“Server” alludes to a specific PC or equipment on which the server programming works and gives administrations to different PCs or customers. A server has numerous capacities, and they come in various sorts to encourage distinctive employments.
A server is a device with a particular set of programs or protocols that provide various services. Together, a server and its clients form a client/server network, which provides routing systems and centralized access to information, resources, stored data, etc.
At the most ground level, one can consider it as a technology solution that serves files, data, print, fax resources and multiple computers. The advanced server versions, like Windows Small Business Server 2003 R2 enable the user to handle the accounts and passwords, allow or limit the access to shared resources, automatically support the data and access the business information remotely. For example, a file server is a machine that maintains files and allows clients or users to upload and download files from it. Similarly, a web server hosts websites and allows users to access these websites. Clients mainly include computers, printers, faxes or other devices that can be connected to the server. By using a server, one can
The greater part of us are familiar with “server”. In numerous spots, for example, schools, workplaces, colleges, and healing centers, there is a PC server that interface the PCs. Be that as it may, what is the genuine motivation behind a PC server?
“The server is down”, “Cannot establish connection to server”… messages of the like have become commonplace in today’s gadget-dependent world. But what is the server that these messages refer to, and what is its place in a network or an organization’s infrastructure? The answer can be one of two things –
A physical computer, whose task is to provide services to all terminals or computers connected to it, such as grant permission or allocate resources.
An entity in the client/server programming model, where the server is a software or a program, running on one or multiple computers, that manages resources and services of the network, while handling requests from different computers to access said resources.
Features of a Computer Server
From the above definition of a server, it is clear this is no ordinary, everyday computer and hence, its hardware should match up to the requirements of today’s needs.
A system topology alludes to the path in which hubs in a system are associated with each other. The system structure characterizes how they convey. Every sort of course of action of the system hubs has its own particular focal points and disservices. Here we educate you regarding the same.
Network topologies describe the ways in which the elements of a network are connected. They describe the physical and logical arrangement of network nodes. Let us look at the advantages different network topologies offer, and their shortfalls.
▸ It is easy to set up, handle, and implement.
▸ It is best-suited for small networks.
▸ It costs very less.
▸ The cable length is limited. This limits the number of network nodes that can be connected.
▸ This network topology can perform well only for a limited number of nodes. When the number of devices connected to the bus increases, the efficiency decreases.
▸ It is suitable for networks with low traffic. High traffic increases load on the bus, and the network efficiency drops.
▸ It is heavily dependent on the central bus. A fault in the bus leads to network failure.
Whether server ranches are endeavors worth putting resources into or not is a long verbal confrontation. One can’t undermine the benefits of setting up one of these sprawling, cutting edge offices for one’s business. Be that as it may, the challenges one may confront while keeping up a server cultivate likewise can’t be overlooked.
Collocation: A Resource-Saving Alternative
Given that the construction and maintenance of a server farm is quite expensive, nowadays, the trend of renting facilities for data centers in lieu of managing one’s own, is on the rise. Companies offering these services are equipped to meet all the infrastructural requirements of a server farm, from providing power supply (along with a electricity back-up), cooling, right up to network bandwidth, and even the hardware itself. Moreover, even security is taken care of.
This mechanism of renting server farms that is profitable both for companies who require data centers, as well as the businesses that provide them, is known as collocation.
A server farm is a large facility that houses server clusters. Since servers are critical to the functioning of majority of the companies in the world, irrespective of their size and the business model they
Intranet, famously known as a private release of the Internet, is utilized by different corporate associations. Business associations advantage from this innovation in different ways. Through this article let us investigate the intranet benefits.
Intranet is a private computer network based on the Internet that can be accessed by the employees of an organization. An Intranet provides easy access to internal files and documents to the various employees of the organization, from their individual workstations. Sharing of data, made possible through the Intranet, not only helps in saving time of employees, but also allows employees from various levels to access data. It also contributes to a paperless office.
Benefits of Intranet
Today’s most modern businesses are adopting intranet technology due its competitive advantages in dealing with the corporate information essential for any business.
Intranet is extremely beneficial for communication and collaboration between the employees for successful functioning of any business organization. Intranet provides this to businesses in the form of tools like discussion groups, Intranet forms, and bulletin boards. Intranet tools help in conveying and distributing necessary information or documents among the employees of an organization.
This results in easy communication and sound
At whatever point you confront organizing issue, the most widely recognized arrangement is to run an investigating program (programming) that will distinguish and settle the issues. Notwithstanding, most generally happening organizing issues can be explained by utilizing straightforward summons like ping, tracert, ipconfig, and so on.
Any person with basic knowledge about networking will recognize ipconfig command. This command gives information about the computer’s IP address along with the DNS, DHCP, Gateway, and subnet mask addresses. The IP address is needed to carry out further troubleshooting commands. If this command returns a 0.0.0.0 default gateway, then you may be experiencing router problems. You may try the variant of this command, to solve your networking problems. Another extension to the above command is ipconfig/flushdns. This clears DNS cache of any unauthorized IP addresses or technical glitches.
One of the most important commands used in networking is ping. This command is used to check the connectivity between the host and destination. The main advantage of using this troubleshooting command is to find out the problem area in the given network. If you run a ping check from any computer in a network, you will get the status of
It is the obligation of a system overseer to keep the system and its associated PCs solid and in full working state. Arrange checking devices make this dull undertaking possible.
In this world of connected devices, network monitoring and analysis has become all the more important since the last decade. Network administrators today have to sometimes manage a network connecting hundreds, if not thousands, of network nodes and critical terminals. Here is the list of best network monitoring tools that you, network administrators, and security enthusiasts, will need for accomplishing your tasks.
It is one of the best open source network monitoring tools. It is very powerful and flexible, but the thought of setting it up manually, puts off many of its prospective users. If you know your organization well and can edit the configuration files manually, then you’ll start liking Nagios soon. Nagios allows planning for infrastructure upgrades before the network outage.
It automatically fixes and responds to issues as soon as they are detected. It can also set alerts in the form of email, SMS, and old-school hard copy printouts. Nagios also keeps a record of network outages, alerts and notifications
Throughout the years, the revelation that the nearness of bent sets of wires inside a link adds to its general flag conveying capacity is genuinely an earth shattering one in the way of link development. Two sorts of bent combine links are regularly utilized today, in particular STP and UTP.
UTP (Unshielded Twisted Pair) and STP (Shielded Twisted Pair) cables terminate in almost-identical connectors. However, the wiring mechanism (the protocol that dictates how many pins of the plug will be used, which wires will carry data in which direction, and other similar specifications) is different in the two.
While UTP cables employ RJ-45 wiring, STP cables generally employ RJ-48 wiring, although it is possible to wire them according to RJ-45 standards as well.
In the field of telecommunication, wiring and cabling are primary concerns, as only by making use of the most suited cables can one successfully implement a network of any architecture, which has a satisfactory throughput yield.
It can be surmised by someone with even the most basic knowledge of electrical systems, that an electrical pulse traveling a distance over a plain copper wire will not reach the other end with the same signal strength.
Keeping in mind the end goal to exchange information between PCs (clients), it is important to associate them to a neighborhood arrange. Switches are the gadgets that interface these PCs to accessible systems. This information exchange ought to occur in a secured way, to keep away from any phishing assaults. Along these lines, a switch utilizes two arrangement sorts, port sending and port activating with a specific end goal to recognize the right port for sharing the secured information.
This configuration type takes care of your computer’s Internet presence, even if you are using a router. Confused? Let us take a look at an example to understand this principle. But before doing so, we will look at few networking basics.
Remember, the port forwarding configuration is available on NAT-enabled routers. Network Address Translation (NAT) is the technology which allows each device in a particular network to have a unique IP address. The entire network will have only one publicly visible IP address, which is used to send/receive data from the Internet.
Let us say, you wish to visit www.buzzle.com, your computer doesn’t send this request directly to the ISP (Internet Service Provider). This request is first forwarded to
For each one of the individuals who have heard this term and are pondering what it is, server ranches are crucial to dominant part of the multi-million Internet marks that we are aware of today, including web crawlers, e-trade entries, and interpersonal interaction sites. Disregard Internet-based organizations, it is the right hand of any vast endeavor.
A server room or data center is a must-have for all organizations regardless of whether they are big and established, or small and in the nascent stages. This is because it is here that all the server computers, the veritable lifeline of the firm, are housed, and are connected to supplementary network hardware, namely, switches and routers. These servers not only contain all company and client data but also backbone the infallible internal network necessary for the organization’s overall survival.
How does one define a server farm, then? A typical data center or a server room would occupy one portion of the office building, or if the company is housed in a multistory building, probably an entire floor. Server farms, on the other hand, are independent facilities dedicated to housing all the servers of a firm.
The location of the server farm of
Why would it be advisable for one to utilize FTP? Aside from the undeniable advantages it gives, of permitting remote confirmed access to records on a remote server, and their simple exchange regardless of size, FTP is to a great degree simple to utilize; you simply should be knowledgeable with its charges.
File Transfer Protocol is a wonderful tool. It is essentially a networking protocol, that allows one to easily obtain the files he or she desires, such as media (for example, audio or video files), data (for example, .pdf files that span hundreds of megabytes), or even software. It has a lot of practical uses, which include the fact that it breaks the limitations of email (and all the other file-sharing applications one might use), which does not allow users to send or receive a file bigger than a certain size, at one time, and also, it allows only authorized persons to access your stored files, that too from a remote location. Another way to benefit from using FTP is to yourself access your personal files from a remote location by logging into your own computer with the help of it.
Of course, using FTP, just like
One can’t send an email without utilizing SMTP; it is the general standard that is utilized to send electronic mail starting with one framework then onto the next. Be that as it may, due to email suppliers’ inclination to disconnect clients from the real methodology included, clients think that its hard to design or investigate SMTP on their frameworks.
Email is soon becoming one of the most indispensable luxuries available to us as a result of modern technology, one study has found that upwards of 2 billion people use email! But did you know, that irrespective of what web-based email, or internet service provider-based email account you use, the underlying principle of email worldwide is predominantly the same and they use similar protocols? In fact, even though browser-based email titans like Gmail, Hotmail, Yahoo! and the like, use proprietary protocols to send and receive emails on their servers, if they wish to communicate with other companies’ servers, they too need to employ SMTP. Whereas, email client software such as Eudora, and Outlook, completely use SMTP to push their outgoing mail from the client’s computer to their servers, and further to the recipient’s email server.
When you have Google,
The Internet that we know has been planned around the system of IPv4 as far back as its initial days. In any case, the present circumstance introduces a requirement for more delivers to coherently distinguish gadgets and systems, and IPv4 is no longer up to the undertaking. Enter IPv6, the cutting edge that guarantees to beat the majority of IPv4’s restrictions.
In this present age, it is impossible to imagine communication of any kind at all without the Internet Protocol, or IP. Networks around us, including the broadband (or any other variation of) Internet connection provided to us by our Internet Service Providers (ISPs), local area networks (LAN) in our school or place of work, mobile networks provided by our carrier, and wide area networks (Wi-Max, for example), all thrive only because they employ the IP logical addressing scheme, the worldwide standard, as their backbone (or in rare cases, they make use of a different network layer protocol that is translatable to IP).
The IPv4 protocol, which was defined in the early 80s, when the concept of the Internet was still in its nascent stages, has been the predominant IP standard for more than two decades. But since
Video links are a critical part of visual electronic gadgets. What’s more, such links come in different sorts to meet the prerequisite of various gadgets.
Not all video cables function in the same way. Their make and design allow them to be used for transmitting video signals in different manner. For example, the cables which are used for a normal home theater system, are most likely to produce undesirable results if used for high-definition home theater system. The below gives you a glimpse on the different types of cables used for different video systems.
Types of Video Cables
Standard Video Cables
These, as the name suggests, are the most basic types of video cables that are used for basic video viewing. As you must be aware, these cables are grouped together with two audio cables, as they cannot carry audio signals. These cables are commonly used for VCRs, DVDs, etc.
These types are commonly used in general home video equipment, cable systems, for Internet connections, and as connectors between radio transmitters and receivers. Also known as coax, these cables consist of copper core (main conducting medium), and this has a wrapping of flexible dielectric insulator. Now this insulator
Sharing documents is one of the least demanding and quickest method for getting to assets and is utilized as a part of any system. This article will familiarize you with the fundamental strides and essentials to share documents between PCs.
File sharing in a network is one of the important reason why the computers are connected. But many of us who have recently setup a network, are often unable or find it difficult to share the data. In other words, the hardware part is done, the computers are connected, but how to get the network into action? Sharing files between computers is not a difficult task. Let us go through various considerations and steps that are required to undertake this task.
Here it is assumed that you have already completed the hardware part for creating your network. Now, let us proceed to the other prerequisites. You need to first consider if the IP address in all the systems is set up in the same scheme. Each IP address should be different from the other, but the scheme should be same. It implies that, the IP address of the computers in a network should be in the same class.
Usually utilized for digital TV signs and Internet organize associations, coaxial links assume a vital part in our every day correspondence and data broadcasting needs. In this article, we will investigate the contrasts between two of the most prevalent assortments of coaxial links – RG-6 and RG-59.
All coaxial cables are constructed with a steel, copper, or aluminum conductor core, which is surrounded by a layer of white/black dielectric insulation. This is further covered with a tube-like braid of copper wires, which is wrapped around by a solid polyvinyl chloride insulating cover called a jacket. Some coaxial cables may have a layer of foil between the dielectric and the conducting core. Coaxial cables use the RG system to differentiate between the various kinds of cables. RG stands for an obsolete military term ‘Radio Guide’. The numbers are used to distinguish one cable from the other, but they are assigned randomly and carry no specific meaning.
RG-6 and RG-59 are two of the most common varieties of coaxial cables, i.e., cables that conduct electricity to transmit signals of radio frequencies, computer networks, and cable televisions. You may also find these cables designated as RG-6/U or RG-59/U, but there is
