Children’s Computers – A Tool to Consider in the Computer Age

The computer era has dawned. Going forward a strong technological skill set and knowledge base will be mandatory in both business and leisure. A weak or limited aptitude in technology will limit options available to everyone young and old. Not only will a lack of computer knowledge prove to be a burden in obtaining employment but it will hamper ones ability to research properly, network efficiently and maximize use of limited time constraints. Many parents, therefore, are encouraging their children as early as possible to get acquainted technology via a children’s computer.

Still, in spite of the widely evident and much anticipated on-going need for children to develop proficiency with regard to computer literacy, many parents still have reservations about the children’s computer. This reaction is quite normal considering the extreme gap that exists between the two generations with regard to technology. Many parents today had limited if any, exposure to modern day technology and certainly not to the degree available today. Many saw a computer as tool used in their place of employment or gadget for entertainment. A children’s computer to them may seem akin to a children’s telephone or a children’s VCR or DVD player.

A spectrum of possibilities exists. A children’s computer can be the same computer used by the rest of the family with some parental controls and special software added. It can be an older, slower computer that is not connected to the internet and runs learning software available at the local library. On the high end, machines are available that have special buttons and keys that are allow small fingers to easily type and …

Layer 2: Data Link: Includes the Network Interface Card (NIC), which serves as the interface amongst the pc and the network. The NIC is typically built into the motherboard and is assigned a Media Access Handle (MAC) address that offers each program connected to a network a special ID. The MAC address is utilised to guarantee that information is delivered to the right pc, and NICs use electricity to send and receive packets of binary data as pulses of electricity, light, or radio waves.

Routers are utilized to connect networks together and route packets of information from 1 network to an additional. Routers, by default break up a broadcast domain, which is the set of all devices on a network segment that hear all broadcasts sent on that segment. Successful monitoring is of utmost value for personal computer network security. It aids in competent management of networks, in which the activity log of routers and varied servers can be closely watched and reported.
