Hot Tech Careers for the 21st Century

“Manager,” “CEO” and “administrative assistant” are old-school. In the networked economy, there’s a whole new class of job titles coming to an HR department near you. Here are some of the technology-related jobs that will be in demand in the 21st century and beyond.

Network Experts

According to a recent study by IT placement agency Robert Half International Consulting, networking is the most in-demand IT specialty. Thirty-two percent of the 1,400 chief information officers surveyed cited networking as the highest growth area within their IT departments.

Gary LaFave, president of InfoTech Contract Services, says, “With telecommuting on the rise and the high demand for sharing and accessibility to data, the person who understands the connection on both the local and global fronts will be in most demand.”

These global network architects need to comprehend communication and information at a much higher and more complex level, explains LaFave. They will need to be knowledgeable in Internet, voice, data and cable capabilities as they come together in the next few years.

@coolnezz... tnx for answering the question #1.

Now, how you may differentiate LLC and MAC? These are the 2 sub-layers at layer 2.

Further explainations; routing and routed protocols

A protocol is a set of rules that determines how computers communicate with each other across networks. Computers exchange data messages to communicate with each other. To accept and act on these messages, computers must have sets of rules that determine how a message is interpreted. Examples include messages used to establish a connection to a remote machine, e-mail messages, and files transferred over a network.

A protocol describes the following:

The required format of a message
The way that computers must exchange messages for specific activities

A routed protocol allows the router to forward data between nodes on different networks. A routable protocol must provide the ability to assign a network number and a host number to each device. Some protocols, such as IPX, require only a network number. These protocols use the MAC address of the host for the host number. Other protocols, such as IP, require an address with a network portion and a host portion. These protocols also require a network mask to differentiate the two numbers. The network address is obtained by ANDing the address with the network mask.

The reason that a network mask is used is to allow groups of sequential IP addresses to be treated as a single unit. If this grouping were not allowed, each host would have to be mapped individually for routing. This would be impossible, because according to the Internet Software Consortium there are approximately 233,101,500 hosts on the Internet.



A routed protocol:
Includes any network protocol suite that provides enough information in its network layer address to allow a router to forward it to the next device and ultimately to its destination.
Defines the format and use of the fields within a packet.
IP, IPX, AppleTalk, DecNet, XNS (Xerox Network System)


A routing protocol:
Provides processes for sharing route information.
Allows routers to communicate with other routers to update and maintain the routing tables.
RIP, IGRP, EIGRP, OSPF,IS-IS, BGP
