Write the disadvantages of internet?
Ans. 1) Children have free access to pornography.
2) Makes people too lazy to refer books.
3) Wastage of time by kids and adults on internet chatting.
4) Internet can give false information on certain subjects which makes books a better option. (eg: some ''wiki'' articles are not reliable) 5) Cyber friendships sometimes lead to extreme dangers like kidnaps, rapes etc, when both parties meet in person. 6) Virus attack is a major problem.

7) Internet posture which can lead to various health problems. gaming gives people long time exposure to computer screens and bad sitting

Qii Write the difference between LAN and WAN?
Ans There are two basic types of network, the LAN and WAN. LAN stands for local area network and WAN stands for wide area network. There are obvious differences between the two network types. To begin with local area networks. They are smaller networks, usually within an office base. Connections between the workstations are physical, with cables, and all the office resources are shared and distributed between the network workstations. The most common type of LAN is that of Ethernet. This is a family of frame-based computer networking technologies for LANs. [pic]WAN, or wide area networks, are broader geographic networks, like one city to another. They are more of a collection of interconnected LAN networks. Other WANs, provided by service providers, connect local networks to the Internet. In actual fact the Internet is more a specific Internetwork, not a straight WAN. While LANs are smaller, collectively they can be linked to create the WAN.

Qii Write the difference between LAN and WAN?
Ans There are two basic types of network, the LAN and WAN. LAN stands for local area
network and WAN stands for wide area network. There are obvious differences between
the two network types.
To begin with local area networks. They are smaller networks, usually within an office
base. Connections between the workstations are physical, with cables, and all the office
resources are shared and distributed between the network workstations. The most
common type of LAN is that of Ethernet. This is a family of frame-based computer
networking technologies for LANs.
WAN, or wide area networks, are broader geographic networks, like one city to
another. They are more of a collection of interconnected LAN networks. Other WANs,
provided by service providers, connect local networks to the Internet. In actual fact the
Internet is more a specific Internetwork, not a straight WAN.
While LANs are smaller, collectively they can be linked to create the WAN. This really
is done using a series of routers, and bridges, which are basically network hardware
devices which enable interconnectivity between separate LANs. With the option of
expanding into small-scale WANs.
The real contrasting features of LANs in comparison to WANs is that of their data
transfer rate, need for leased lines and geographical range. LANs are faster, with 10 GB
data transfer rates. Likewise, as has been mentioned, LANs encompass a smaller
geographical area. WANs also rely on common carriers, while LANs do not.
Aside from these differences users of a LAN will more likely need password validation
as it will have specific user rights. While smaller WANs might also have this, it is less
likely. LAN networks will generally be more private than WAN networks, and will have
some sort of networking software and probably a network administrator. Hardware
resources are shared on a LAN, while with a WAN the focus is more on communications.
The network topology of LANs is often peer-to-peer. That is to say, each client shares is
resources with other workstations in the network. WAN networks will operate on a more
