Computer Network Management
Today it is almost inconceivable for a business not to have computers, whether it is a construction company or a high technology firm. When a business has more than one computer, they are almost always connected together in a local area network. These networks may be more or less advanced and therefore more or less costly.
Companies invest so much (in terms of both money and time) in a local area networks because there are many advantages that a local area network brings to a business and how it is administered.
Some businesses use a local area network in such a way they are highly dependent on it always working. If the company’s network fails, then you may see all the employees chatting away in the corridors because they can’t do their work. This means big losses for the company and causes stresses on the employees. All companies must consider their local area networks a vital asset and downtime must be avoided. This imposes huge demands on the network staff to keep such networks running almost 100% of the time.
The advantages of Computer Network Management
One of the main advantages of installing and maintaining LANs is the opportunity they create for better communication and cooperation between employees and customers.

What To Expect When Taking Your First Cisco Certification Exam
Cisco Certification: Taking Your First Certification Exam
You’ve studied hard you’ve practiced your configurations you’ve used your flash cards over and over again and finally, the big day is here. Your first certification exam!
For many Cisco certification candidates, their first exam is the CCNA Composite exam or one of the two exams that make up the CCNA, the Introduction To Networking exam or the ICND (Interconnecting Cisco Networking Devices) exam.
Walking into a testing center for the first time can be a nerve-wracking experience. You’ve got enough on your mind just keeping all that new information straight without worrying about what the testing experience will be like.
You’re not there to take the exam. You’re there to pass the exam. With this aggressive attitude in mind, let’s take a look at what you should expect (and not expect) when taking your first Cisco certification exam.

Cabling your home for computer network – still a requirement?
Cabling your home for computer network – still a requirement?
With proliferation of wireless networking and communication equipment it is oh-so-tempting to cut the cord and save a significant sum of money in the process. But is everything that a regular computer networking user needs can be done using just wireless network? Let’s take a look at some pros and contras:
1. One important advantage of having a cabled network is the available bandwidth or simply speed. At the present point in time the speed of connection via a simple and inexpensive CAT5E cable can be 1000Mbit/sec, whereas the best that IEEE802.11g (one of the many flavors of Wi-Fi) can offer is only 54Mbit/sec. It may not seem so significant if you think you are only browsing Internet, and the DSL speed available to you is 1.5Mbit/sec. However, if you need to print via your network connection on a remote printer, you should realize that the print jobs, depending on the amount of graphic data in them, can easily reach dozens and even hundreds megabytes. Since 1Byte=8bit one 100MByte print job will take 15 seconds (and in reality this time can be much longer) to transmit via a Wi-Fi wireless connection, and this time shrinks to mere 1 sec or less on wired 1000MBit/s Ethernet connection. Same principal applies to transferring files, backing up files on other computers in the network etc.
