Six Top Tips To Improve Your Computer Security
6 steps for safe online surfing and shopping.
How to Reset your LinkSys Router’s Password
All LinkSys router passwords are normally set up at the same time as the initial router setup but may be changed at any time. For security purposes the default password “admin” should be updated. It is important to reset the password in order to avoid unauthorized users from accessing the router’s web page. Updating the password from the default password is also an important step in enabling the remote management option. Again, the Linksys router’s default password is “admin”. All Linksys routers have a built-in web-based setup page where users may customize settings and set up advanced properties. Password details are included in these setting options.
Cisco Router Password Recovery
Retrieving your password using the majority of Cisco routers is easily achieved by accessing the console port. The problem is that Cisco has bought out a large number of other companies and placed their company label on the router. As a result, password retrieval procedures differ significantly among Cisco devices. Furthermore, the retrieval process changed significantly because of IOS upgrades. The intent of this article is to offer basic instructions that will allow the majority of Cisco device users to accomplish this task. Through following these instructions, you will be able to retrieve your lost password from most Cisco routers. Please note that these instructions are designed to assist those using the 2000, 2500, 3000, 4000, 7000, and IGS devices.
What is the Purpose of an Ethernet Crossover Cable?
An Ethernet crossover cable is a cable that can be used to create a very simple computer network. To create a computer network, one must join at least two computers together for sharing program files and data. Sometimes, computer networks are extremely complex, involving many computers, as well as routers and hubs. Each of these computers interacts and shares data with the others.
How do you explain the purpose of the OSI model?
The reference model used by most Intelligence Technology (IT) experts to explain the functions of both networks and their applications is the Open System Interconnection, or OSI model. This concept was originally developed for the purpose of describing an entire range of protocols for production networks. The expense and intricacy of the programming process required to successfully define this network made this descriptive project unfeasible. Furthermore, while the OSI designers quibbled over individual responsibilities of the application’s features, the Transmission Control Protocol/Internet Protocol, or TCP/IP, became the world’s standard instead.

A Succint Story of the Memory Card
Memory cards were initiated around 1990 when technology in mobile phones and digital cameras started to develop and become more complicated. Nowadays it’s not strange to have a mobile phone with a en suite camera of 5 mega pixels which lets you to capture photos of big resolution. As in-built storage on phones is very small, on average around 10MB, the need for extra storage came about and so the memory card, the SDcard was one of the first.
The world’s best 4x4’s
Did you ever wonder to yourself, what the soccer mom who races from band practice to Pick ‘n Pay does with a Land Rover Discovery? Will she ever use this fearsome beast to conquer the open wilds? Will she ever scramble across mud and desert, changing the tire if a piece of scrap metal rips them open? No. That will never happen. 4x4’s are a status symbol and the bigger they are, the better prepared you are. For the shopping centre that is. So stop rolling your eyes. You know you want one. I mean, who wants to dirty the paintwork? A 4x4 is a considerable investment, often costing double the price of any ‘normal’ car. However, they have many uses outside of taking the kids to school and are sturdy, gas-guzzling beasts. A 4x4 will never let you down.

TTY
In the early days of Unix, teletypewriters or ttys were used by users to communicate over a serial line with the mainframe computer. The mainframe had no keyboard or monitor as it has now and so during those early days, all commands were issued through the tty. The output of the commands was typed on the printer that was part of the tty. The tty terminals had no processing power of their own and hence were known as “dumb” terminals.
Baud Rate
Baud Rate can be roughly defined as the speed of transmission of data between two computers. All forms of communication using the Serial Port requires the presence of four parameters: the baud rate of the transmission being the very first parameter, then comes the number of data bits encoding a character, the third in line is the optional parity bit, and last one is the number of stop bits. Each character transmitted using this method uses a character frame that has a single start bit, then data bits, the parity bit which is optional, and lastly the stop bit(s).

What is a netmask calculator and how do I calculate it?
A netmask calculator is basically a script or a program that automatically calculates the netmask numbers for you. Netmask is simply a code of numbers that is used to correctly transfer messages among machines in the same subnet. So, a netmask would work together with the router to determine whether the data goes. For example, if the host’s IP address was 63.243.31.41 and the netmask was 255.255.255.0, the netmask is responsible for telling the machine what numbers in IP address are the subnet and what numbers in the IP address is the machine. In this case, 63.172.202 would be the subnet part while 41 would be the machine part. So, any machine in the 63.172.202 would be part of the (local) subnet and thus, the netmask is exactly what assists in differentiating the IP address.
Define Global Catalog
Domains and Forests can also share resources available in active directory. These resources are searched by Global Catalog across domains and forests and this search is transparent to user. For example, if you make a search for all of the printers in a forest, this search goes to global catalog server for its query and then global catalog returns the results.
