Socialism Vs Capitalism

I was discussing sociallism vs capitalism with my father, who is a retired economics professor. Found some interesting facts ... Sharing them ... Socialism believes in distributing wealth equally. For example: If there is INR 10000 and 10 people in the pool, every one gets INR 1000. Wow, that sounds great in a diversified society like ours. Will this work? My take is NO. Because, the focus is only on sharing the wealth. If every one gets equal share, high acheiver will downgrade himself or herself and low acheivers will still downgrade themselves. This is a chain reaction and will reach a point where you will not have anything to distribute. The opposite side is 'Capitalism' where only the acheiver gets the rewards for his or her efforts. India adopts hybrid policy of Socialism and Capitalism, where the distribution of wealth happens through public sector enterprises and wealth creation happens through private sectors. The policies will be made in such a way that private se...

Sub-netting: Divide a network into 2 or more networks

Points to keep in mind: 1. Computers that belong to a subnet are addressed with an identical most-sig bit group in the IP addresses 2. IP is logically divided into NetworkIdentifier/Routingprefix and Restfield/HostIdentifier 3. Routing prefix can be expressed as CIDR (Classless Inter-Domain Routing) notation. Ex. 198.51.100.0/24 Implies NetworkIdentifier has 24 bits allocated and Rest field has 8 bits allocated 4. A network is characterized by subnet mask or netmask, applied by bitwise AND operation Ex. For 198.51.100.0/24, the subnet mask is 255.255.255.0 Subnet masks are used to identify the networks *If 198.51.100.0 is NetworkIdentifier, then 198.51.100.255 is BroadcastIdentifier For Class A, mask is 255.0.0.0; Class B, mask is 255.255.0.0; Class C, mask is 255.255.255.0 5. Traffic is exchanged between subnets through routers, when the routing prefixes of the source and destination addresses differ; A router serves as a logical boundary between the subnets. Advantag...
