Network+ Certification?
• CompTIA Network+® Certification• CompTIA Network+ validates the knowledge and skills of networking
professionals. It is an international, vendor-neutral certification that recognizes a technician's ability to describe the features and functions of networking components and to install, configure and troubleshoot basic networking hardware, protocols and services. Although not a prerequisite, it is recommended that CompTIA Network+ candidates have at least nine months of experience in network support or administration or adequate academic training, along with a CompTIA A+ certification. In fact, many IT certifications integrate CompTIA Network+ into their curriculums. Microsoft added CompTIA Network+ into their Microsoft Certified Systems Administrator (MCSA) program, and other corporations such as Novell, Cisco, HP, Lotus and 3Com also recognize CompTIA Network+ as part of their certification tracks.

Network Type

• Metropolitan Area Networks (MAN)
• Wide Area Network (WAN)
![Page 48: Tips from Pavan NIIT Beawar](https://reader036.fdocuments.us/reader036/viewer/2022062318/55283cf049795921048b468c/html5/thumbnails/48.jpg)
LAN
• A local area network (LAN) is a computer network covering a small physical area, like a home, office, or small group of buildings, such as a school, or an airport. The defining characteristics of LANs, in contrast to wide-area networks (WANs), include their usually higher data-transfer rates, smaller geographic range, and lack of a need for leased telecommunication lines.

MAN
metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN).

Why do we need SP?
You can not have failed to hear about all the virus, worm, hacker and Trojan attacks that have plagued the Windows community over the few years!
Perhaps you were even a victim to at least one of them?
Well, Microsoft have put together a comprehensive package to address the security concerns these attacks have raised for Windows XP users.

Service Pack
• A service pack (in short SP) is a collection of updates, fixes and/or enhancements to a software program delivered in the form of a single installable package. Many companies, such as Microsoft or Autodesk, typically release a service pack when the number of individual patches to a given program reaches a certain (arbitrary) limit. Installing a service pack is easier and less error-prone than installing a high number of patches individually, even more so when updating multiple computers over a network.

Ban Shutdowns : A trick to Play on Lamers
• This is a neat trick you can play on that lamer that has a huge ego, in this section I teach you, how to disable the Shut Down option in the Shut Down Dialog Box. This trick involves editing the registry, so please make backups. Launch regedit.exe and go to :
• HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
• In the right pane look for the NoClose Key. If it is not already there then create it by right clicking in the right pane and selecting New > String Value.(Name it NoCloseKey ) Now once you see the NoCloseKey in the right pane, right click on it and select Modify. Then Type 1 in the Value Data Box.

Instead of performing the above difficult to remember process, simply save the following with an extension of .reg and add it's contents to the registry by double clicking on it.
REGEDIT4
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"NoClose"="1"
