Computer Data Networking Explained
Jul 16th
In the business world the term “networking” usually refers to the process of establishing relationships with people who can help grow or expand your business. In a social sense, the term “networking” may refer to the process of making contact with like-minded individuals who share your interests. Facebook and Twitter, for example, are two sites that make social networking possible. But in the computer world, or more specifically the world of Information Technology, the term “networking” has an entirely different meaning. In this article we will take a look at computer networking in a bit more detail, including some examples of networking with which you may already be familiar.
What Is Networking?
In computer-speak, the term “networking,” also known as data communication, is a discipline within the field of computer engineering which is primarily concerned with the communication between computer systems. Thus, a computer network refers to any computers – or related devices – which are connected to one another for the primary purpose of exchanging data.
So what are some examples of computer networking?
Computer networks are very common in businesses and other organizations, allowing multiple users to share and manipulate the same data and communicate with each other securely at any number of independent workstations. In office settings, for example, networking enables every employee to work from the same collection of data (such as a large database) without having to make changes to each computer every time the data is updated or modified.
Networking has also become increasingly popular for home users. Perhaps the best example of this is when laptops and other devices are networked to a desktop computer wirelessly through a network router. Other devices can also be networked. Printers, for example, can be included in the home network so that each computer can give the print command to a single printer.
Data Recovery Hardware

Owning a computer is one thing and repair and maintenance is another. Usually, these technical machines do not require too much human attention. All the same, they can become quite troublesome if they develop hard drive mechanical problems. Many computer users and technicians recognize how complicated harddrives are. First, it is difficult to understand their craftsmanship. They have quite a few moving parts and a circuit board. If HD abruptly fails, help with data recovery hardware is inevitable.
For sure, it is difficult to trace a hardware problem on hard drives. It can be because of a physical damage to the circuit board. If not, the actuator arm could have serious problems that only a technician can discover. A hard drive with such problems will most likely have some strange noises. Such grinding noises should signal a crisis and one must disconnect such a drive right away. The next wisest step to make is searching for a reliable data recovery expert.
Currently, finding a computer technician must not be a hassle. Try searching on the Internet and focus on those available locally. These experts know how to open hard disk drives and to dismantle their parts. Anyone who cannot repair a damaged drive at home should seek professional help. Needless to mention, this is not an easy task and that is why these services are somewhat expensive. Technicians are so careful to avoid stuff that would only aggravate a harddrive problem, such as particles. Moreover, they use specialized tools to identify any mechanical hitch.

Brainstorming to Collect Data in Designing the Corporate Computer Network
Oct 29th
Suppose that you are appointed to lead a project of a computer network design in your organization that contains many sites that need to be integrated into a single corporate private network, what are you going to do? As a team leader, a time-frame project as general needs to be developed first that includes the brainstorming to collect data as much as possible, the blueprint project, budget forecasting, liaising with the third parties and so on.
It’s quite difficult to start a project properly without knowing exactly what the strengths and weaknesses of supporting infrastructure which the system will base on. It is therefore, a computer network design should start by brainstorming to collect data as much as possible.
Assume this computer network design will involve three sites: one main headquarter office in Sydney, one main office in Jakarta, and one remote site – the gold mine in the middle of the Borneo jungle. The principal of the organization would like to have all the sites linked to a single corporate computer network to allow inter-sites communication including data, voice, or probably video conference and off course to allow easy communication with the whole world.
Telecommunication Requirements
The first data for your computer network design that needs to be collected is the telecommunication system requirements. The main question is how to link all of the sites to allow system communication to happen. The following questions can be used to collect the data for the telecommunication requirements.
Securing Data over Computer Networks
Sep 29th
When designing a network, data security must be included in the design plan because protecting data while it is transmitted is very important especially if is is sensitive data. additionally, authenticating users when trying to open protexted pages is also very important to avoid stoling data. finally receiver must assure that the data is received as transmitted. the previous points are explained below separately.
When transmitting data across a network, many attackers exist that can intercept the data and read it. the data are transmitted in the form of binary signals. any one having a detector can read this pulses on the line. the data transmitted can be very sensitive especially in milattery applications.
The solution to the above problem is to scrample the data before transmitting them according to some rules. on the receiver, these rules must be known in order to extract the original data from the scrambled data. this process of scrampling is called encryption. encrypting data involves replacing each block of data with different block or shifting a block to the place of another block.
Another issue for network security is user authentication. when some one opens a protected page on a site or download a protected file, he must provide the server first with the username and password. this is done to know that the person who atempting to open the page or download the file is a known person who is allowed to do so. this process is called authentication. generally, authentication involves matching the user credentials with a set of credentials stored on the server.
