What Is a LAN (100) Cable?

Local Area Network" or LAN is a term meaning "private network." The dominant set of standards for the physical properties of LANs is called Ethernet. The Ethernet standards are published by the Institute of Electrical and Electronics Engineers and periodically updated to create better performing networks. The "100" LAN refers to one of these standards.

Ethernet
Ethernet was originally a proprietary networking system owned by Xerox. The early Xerox standards recommended the use of coaxial cable. In 1983, the responsibility for managing the standards was handed over to the IEEE, and Ethernet became an open standard. An open standard is available to all, either free of charge, or for a subscription fee. The IEEE has since produced a number of amendments to the Ethernet standards; each carries the code 802.3, followed by one or two letters to indicate a series.

Naming Convention
Although the IEEE uses the 802.3 code for all its Ethernet standards, the complete LAN systems it defines are given a different code. This naming system has three elements. The first is the data throughput speed. Originally, this was expressed in megabits per second, but later systems are given a code based on gigabits per second. The next part of the name gives its transmission method, which is either baseband or broadband. The final part is a code for the cable type of the network.

How to Invert Colors on Microsoft Office Picture Manager

Microsoft Office Picture Manager manages and edits digital pictures. This program includes "Hue and saturation" settings that allow you to adjust the color on a scale. Click and drag the slider on the "Amount" or "Hue" scale for a custom look. Saving this edited file as a separate copy from the original keeps the original file intact for reference. Step 1 Open the saved picture file in "Microsoft Office Picture Manager." Step 2 Click on "Edit Pictures" on the Formatting toolbar. Step 3 Click on "Color" in the "Edit Pictures" pane to the right of the picture. This pane includes "Hue and saturation settings." Step 4 Click on the "Hue and saturation settings," such as "Amount" or "Hue." Click on the slider to achieve the desired effect. You can also enter a value in the settings text box. Step 5 Save this file as a copy with a file name different from the original

Performance evaluation for proactive network management

  Local area networks (LAN and Wi-Fi) are decisive factors in the ups and downs of IT performance, alongside the computer center. But running the LAN infrastructure requires considerable staff and financial resources. T-Systems takes over this task on request and guarantees success with its SLA (service level agreement). This arrangement gives companies security and facilitates a high-performing company network IT employees can breathe a sigh of relief. With managed LAN services, T-Systems takes over all tasks around the active components of the company network. T-Systems configures ports and Wi-Fi access points. As well as this, the managed service contractor provides the necessary hard- and software, including IT services. Services like proactive monitoring and technical reporting are of course also included in the agreed all-round and care-free SLA service. Cloud services are also growing in significance. T-Systems has recognized this and offers a network solution controlled complet

What is the LM authentication protocol?

The LM authentication protocol, also known as LAN Manager and LANMAN, was invented by IBM and used extensively by Microsoft operating systems prior to NT 4.0. It uses a password encrypting technology that is now considered insecure. LM works by creating a "hash" of your password, as follows: Breaking the password into seven-character chunks: If the password length is not a multiple of seven (i.e., 7, 14, 21, 28...), LM pads the remainder of each chunk with zeroes to make it a full seven bytes long. For example, a ten-letter-long password would be divided into a seven-character-long chunk and a three-character-long one, and the smaller one would have zeroes added to it to push it up to seven characters. Mapping all lowercase letters into uppercase: For example, Dog becomes DOG. Encrypting each chunk: LM uses each chunk as a 56-bit DES (a standardized cipher standard) key to encrypt the following string: KGS!@#$%. Concatenating those strings (i.e., linking them end-to-e
