All about Telnet

Introduction:

Telnet is used to connect to remote machines through emulation. This means that it can connect to a server, any server instantly because of it’s ability to emulate (copy) remote computers.

In Windows, Telnet can be found by going to Start -> Run and then typing telnet. The application should then pop up. If you don’t have Windows, there are many Telnet alternatives for mac, linux etc. Since I don’t know any,search the internet for Telnet for Linux or Telnet for Mac and you should find something instantly.

If you have a PC and are using Windows 98/95, 2000, Me, or XP continue…

As you can see, Telnet has 4 menu options. These are Connect, Edit, Terminal, and Help.

If you click Connect, you should see more options. Here they are.

Connect:

Remote System..

Disconnect

Exit

Names of servers you have been on.

To connect to a server, click Remote System…

This will then take you to a dialog box that has these fields:

Hostname:

Port:

TermType:

There should also be a Connect button and a Cancel Button.

Lets go over these & what you should put in them.

-Hostname-

The Hostname can be the address of the website your going to be connecting to:

http://www.computerzworld.com

or it can be the IP address. Keep in mind that you can only connect to servers and not to clients (other PCs)

an IP Address looks like this:

100.101.102.103

-Port-

Port can bb either the port number you wanna connect to on the server (Port 80 is the Internet, Port 23 is Simple Mail Protocol then there are some more ports for different things.

or you can keep it Telnet and see what happens.

-TermType-

TermType is the type of Terminal telnet will be acting like.

This doesn’t matter most of the time, so you can keep it to default or try other ones if you want.

When you have all this set up, you can Click Connect & see what happens.

Note: Sometimes many servers don’t like anon people just logging on, so be careful when logging onto servers, because sometimes it might be some big company that likes bullying people or just SOMEONE who likes bullying people and then they might want to find you or trace you or something and I know for a fact you don’t need that happening.

Another Note: When you go to a server and type something, such as a login name or a password, you might not see anything even though you are typing. this is a feature that telnet or the other server uses. It’s for some kind of safety measure.

Ok that’s all for the Connect Menu, lets go over the Terminal menu.

The terminal menu should have 3 options:

Prefernces

Start Logging

Stop Logging.

-Prefernces-

If you go to this, a dialog box will come up with various options. Here, you can change the text color & background color of the program, and you can enable Local Echo, which shows you everything you’ve typed, Blinking cursor if you want the cursor to blink check it, if not uncheck, Block cursor if you want the cursor to be shown as a block, VT100 Arrows, don’t worry about these they are useless, Buffer Size, this allows you to set the number of lines of text you want to be shown before the screen starts to scroll, The Terminal emualtion type, always have this set on the default unless you know what the second one is and you know what your doing.

-Start Logging-

This logs everything you do on Telnet in a log file on your computer.

-Stop Logging-

This will stop logging processes.

Change default location for installing applications

As the size of hardrives increase, more people are using partitions to seperate and store groups of files.

XP uses the C:\Program Files directory as the default base directory into which new programs are installed. However, you can change the default installation drive and/ or directory by using a Registry hack.

Run the Registry Editor (regedit)and go to

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

Look for the value named ProgramFilesDir. by default,this value will be C:\Program Files. Edit the value to any valid drive or folder and XP will use that new location as the default installation directory for new programs.

Laptop categories

Laptops are some of the most widely used gadgets of the 21st century. Their appearance and development during the last 3 decades made our everyday life easier. Laptops are used almost everywhere: at homes and offices, hotels and means of transport. According to the amount of space, people buy laptops of various sizes. Thus there are several categories of notebook computers. Every design and size corresponds to the user’s specific needs.

There are five categories of laptops. Every category has its advantages and disadvantages.

Ultraportables (weight: under 4 pounds)

It represents a very compact notebook that one can carry in a small bag. Computers from this category have low demands, which is why they are quite small in size. An ultraportable laptop has a futuristic design, a light weight and it represents a perfect choice for a traveler.

However, ultraportables are meant mainly for less space rather than high performance. They are not meant for high-demand business applications and games that require intense graphics. The smaller is the laptop the less life its battery will have. The screen is small and a high resolution can be hard on one’s eyes.

Because of its small size the keyboard has smaller buttons which is not very comfortable for those with large fingers. Light ultraportbles do not include CD and DVD drives. The latter serve as external accessories. However these drives can be found on heavier laptops from the ultraportable category.

Standard Laptops (weight: 6 to 8 pounds)

Almost every standard laptop includes DVD/CD-RW drives. This category is very popular and the prices are more affordable than notebooks from other categories. The average battery life is about 3 hours but there are high-capacity versions that are able to work for 5 hours. The standard laptops are not as compact as ultraportables. The user will also have to carry additional peripherals in order to read various media card formats. The same concerns the connection to other devices.

Thin and Light (weight: 4 to 6 pounds)

Laptops from this category have powerful processors. Most thin and light notebooks have 14 inch displays, which allow viewing everything from Word and Excel files to various internet pages. The battery is able to live for more than 3 hours. There are a lot of thin and light laptops that have the ability of swapping out an optical drive. Notebooks from this category are able to transfer the information wirelessly (for example through Bluetooth) without a significant drain of battery life.

There are also several ports available: USB 2.0 and parallel. Some thin and light laptops encounter even serial ports. This category is popular for the ability of connecting a video camera.

Desktop Replacements (weight: 8 pound and up)

This category includes laptops with wide screens, sharp displays as well as great graphical performances. Desktop replacements are perfect for gaming and business performance. This is due to the fast CPU and improved video chips. These laptops have improved audio systems and some of them also include subwoofers.

One of the disadvantages of desktop replacements is their size. For example they will not fit under an airplane seat. Another negative aspect is their battery life.

This category includes some of the most expensive computers on the market today. The price varies from 1,500 to 4,000 US dollars.

Tablet PC (weight: 2 to 4 pounds)

The main advantage of the table PC is their touch screen. This feature is very useful for some specific professions like, for example, medicine. These computers are also able to convert hand writing into editable text. The user can view tablets in two modes: regular and pivoted on end. Thus one can switch the table screen to a portrait mode.

Laptops from this category have the longest battery life among other categories. The disadvantage of tablet PC is their slow processor and little RAM. These notebooks are not meant for business or gaming performances. The CD and DVD drives are very often add-ons connected as external sources.

According to a laptop’s performance one can choose a notebook suitable enough for his or her lifestyle. The market of laptops continues its expansion adding new additional features satisfying even more of customers’ needs.

Create A Huge File

You can create a file of any size using nothing more than what’s supplied with Windows. Start by converting the desired file size into hexadecimal notation. You can use the Windows Calculator in Scientific mode do to this. Suppose you want a file of 1 million bytes. Enter 1000000 in the calculator and click on the Hex option to convert it (1 million in hex is F4240.) Pad the result with zeroes at the left until the file size reaches eight digits—000F4240.

Now open a command prompt window. In Windows 95, 98, or Me, you can do this by entering COMMAND in the Start menu’s Run dialog; in Windows NT 4.0, 2000, or XP enter CMD instead. Enter the command DEBUG BIGFILE.DAT and ignore the File not found message. Type RCX and press Enter. Debug will display a colon prompt. Enter the last four digits of the hexadecimal number you calculated (4240, in our example). Type RBX and press Enter, then enter the first four digits of the hexadecimal size (000F, in our example). Enter W for Write and Q for Quit. You’ve just created a 1-million-byte file using Debug. Of course you can create a file of any desired size using the same technique.
