Which Broadband Modem is Better- Ethernet or USB?



Most of the broadband modems support two kinds of network connections- Ethernet and USB. Both of them serve the same purpose and can work in most of the situations. Users can reconfigure their modem with Ethernet and USB whenever required, but both the interfaces cannot be used simultaneously. So the question arises which type of interface is better

Ethernet is the most preferred option for connecting a broadband modem for various reasons.

First, Ethernet is technically more reliable than USB for networking purpose. You will experience less dropped connections or sluggish response time when using Ethernet over USB.

Next reason is Ethernet cables are able to reach a longer distance than USB cables.
Ethernet cables can run anywhere within a home whereas USB cables are restricted to approx 5m.

Ethernet does not require installation of device drivers, whereas USB require. Modern operating systems are capable of installing drivers for many broadband modems. The procedure varies for different operating system and all the system are not compatible with a given brand of modem. USB drivers can slow down the performance of older computers. Generally, a device driver is an additional installation step and can cause various problems that you don’t have to worry in Ethernet.
Ethernet supports higher performance networking than USB. Both the Ethernet and USB 2.0 interfaces have support for sufficient bandwidth for broadband modem.
Modem speed is restricted by the speed of modem’s connection to your service provider.

Notable advantage of USB interface over Ethernet is the hardware cost. IF the computer that is connected to a broadband modem does not have an Ethernet network adapter, that one should have to purchase it and then installed.
The other advantages of Ethernet that are described above outweigh this up front effort.

If you are looking to make your career in the field of networking then Networkbulls is one of the best institute. Also you can find numerous Network bulls complaints  online but institute is really good and has largest lab.

Remote Access in Computer Networking



Question: What Is Remote Access in Computer Networks?
Answer: In computer networking, remote access technology allows operating a system as an authorized user without any physical presence on the system. It is commonly used in computer networks but can find its applications on home networks.

Remote Desktop
The most complicated form of remote access allows user on one computer to see and operate the desktop user interface of another computer. Configuring remote desktop support can be done by configuring software on both the host and target. After installation of the software we can get a view of the target computer on the host.
Presently we have current versions of Microsoft Windows as Remote Desktop connection software. However, this software only support target computers that run Professional, Enterprise or advanced versions of the O/S which make it unsuitable for  use with home networks. For Mac OS X computer, Apple Remote Desktop software package is available and that too for business networks. For Linux operating system we can see various remote desktop software available as of now.
Many of the remote desktop solutions work on Virtual Network Computing technology. Softwares based on VNC works in multiple operating systems. The speed of VNC and other remote desktop software can differ, where it performs effectively same as the local computer, but at other times it exhibit sluggish responsiveness due to network latency.

Remote Access to Files

Basic remote network access enables files to be read from and written to the target, without any support of desktop capability. With the help of Virtual Private Network (VPN) technology one can have remote login and files access functionality over wider area networks (WANs).

VPN need client software to be present on host system and VPN server technology installed on the target computer. In absence of VPN, client/server software can also be used for remote file access. SSH help to provide a command line interface to the target system.

File sharing in home or other local area network is not considered for a remote access environment.

Operating systems in computer networks



Computers use operating system to build and run programs. Operating system software not only runs on laptop computers but also on network routers, cell phones and other embedded devices.

Types of operating system
The operating systems used on computers are
·     Microsoft Windows
·     Linux
·     Mac OS X
Some other types of operating system used for various types of equipment are
·     Google Android and Symbian- for cell phones
·     DEC VMS (Virtual Memory System)- for mainframe computers
·     Solaris, DG-UX, HP-UX and other types of Unix- for server computers

Network Operating system
A modern operating system has built in software to simplify networking of a computer. In Operating system software, there is an implementation of TCP/IP protocol stack and utility programs like traceroute and ping. This consists of necessary device drivers and other software to automatically enable a device Ethernet interface. Mobile devices provide the programs to enable Wi-Fi, Bluetooth and other wireless connectivity.
Early versions of Microsoft Windows don’t offer any computer networking support. Microsoft has added basic networking properties into its operating system like Windows 95 and Windows for Workgroups. Microsoft also comes with internet connection sharing feature in Windows98 Second edition.
In comparison to UNIX, which was designed with more emphasis on networking. Any consumer operating system today can be categorized as a network operating system due to the growing popularity of internet.

Embedded Operating systems
Embedded system supports no or limited configuration of its software. For e.g. embedded systems like routers typically consist of a pre-configured Web server, DHCP server and some of the utilities but do not allow the installation of new programs. Some of the examples of embedded operating system for routers include
·        Cisco IOS (Internetwork operating system)
·        Juniper Junos
·        DD-WRT
You can find embedded operating system inside the consumer gadgets like phones (iPhone OS), digital media players and PDAs. 

Computer networking is very demand-able courses these days. To be a certified computer network engineer through any institute read first reviews and comments about those institute. It will help you to choose best place to do computer networking courses. Read Network Bulls reviews and complaints which is the best networking institute in North India.
