IP address classes These IP addresses can further be broken down into classes. These classes are A, B, C, D, E and their possible ranges can be seen in Figure below. Class Start address Finish address A 0.0.0.0 126.255.255.255 B 128.0.0.0 191.255.255.255 C 192.0.0.0 223.255.255.255 D 224.0.0.0 239.255.255.255 E 240.0.0.0 255.255.255.255 Figure . IP address Classes If you look at the table you may notice something strange. The range of IP address from Class A to Class B skips the 127.0.0.0-127.255.255.255 range. That is because this range is reserved for the special addresses called Loopback addresses that have already been discussed above. The rest of classes are allocated to companies and organizations based upon the amount of IP addresses that they may need. Listed below are descriptions of the IP classes and the organizations that will typically receive that type of allocation. Default Network: The special network 0.0.0.0 is generally used for routing. Class A: From the table above you see that there are 126 class A networks. These networks consist of 16,777,214 possible IP addresses that can be assigned to devices and computers. This type of allocation is generally given to very large networks such as multi-national companies. Loopback: This is the special 127.0.0.0 network that is reserved as a loopback to your own computer. These addresses are used for testing and debugging of your programs or hardware. Class B: This class consists of 16,384 individual networks, each allocation consisting of 65,534 possible IP addresses. These blocks are generally allocated to Internet Service Providers and large networks, like a college or major hospital. Class C: There is a total of 2,097,152 Class C networks available, with each network consisting of 255 individual IP addresses. This type of class is generally given to small to mid-sized companies. Class D: The IP addresses in this class are reserved for a service called Multicast. Class E: The IP addresses in this class are reserved for experimental use. Broadcast: This is the special network of 255.255.255.255, and is used for broadcasting messages to the entire network that your computer resides on.

Originally, computers were be used to store, calculate, and research data. With the invention of the internet, most computers are used as a bridge for virtual communication, sharing, business, education, media and marketing.

There is no set salary for it because it depends on who you're working for, what area in the country, if you have certification or not. You can start with $23K being new into the field. If you're certified in the field you going for it should be higher but companies are trying to take advantage of who they can when they can for the cheapest amount.

computerized enrollment system tend to replace a what we called "Paper Less" transaction and also it will make any transaction more easier and faster. also it tends to lessen manpower and human efforts in terms of processing any transaction in regards with enrollment transaction.

No, Technology will never be able to replace the role of a teacher whether they are in front of the classroom or in front of a webcam

because,

a. if you're doing homework, stuff with your job, etc. i find that after 20-30 minutes, my brain just cant work any more, it doesn't take stuff in. but...

b. sometimes, it can be bad for your brain, to stare at a television or a computer for a long time, as you can get damaged eyesight.

hope that this helped. :)

==Depends on the type and experience== Starting salaries are pretty impressive. For the major disciplines, Electrical/Electronic, Mechanical, Chemical, and Computer, entry-level salaries range from the high 40s to the high 50s. Civil engineers command less, for some reason: figure the low 40 to 50 thousand. Experienced engineers, especially design engineers, command twice that, but the big money is earned by those who go into engineering management (or who own their own firms). In my experience (large corporations) the answer as of early 2001 was in the neighborhood of $45,000 for a degreed electrical engineer (BSEE) early in his/her career going up to twice that or a bit more for a senior engineer with some truly remakable accomplishments. These are for engineers working as part of a small group or more likely as the senior person with some leadership responsiblity for a small group (half a dozen people). Engineers are not limited to doing engineering, however. Moving into some form of management (engineering department head, sales manager, plant manager, director, or higher)lead to significantly higher earnings than one can expect when working strictly as an "engineer". Please search the web for a more current answer. Chemical engineers made the most in a recent (2006) article I saw, and software engineers were right there at the top too. • Experienced engineers 2001 Average Salary: • Federal Government ,170 • Search and navigation equipment ,020 • Aircraft and parts ,230 • Guided missiles, space vehicles, and parts ,830 • Average starting salary in 2001: • bachelor's degree candidates in aerospace engineering received starting offers averaging ,918 a year • master's degree candidates were offered ,955 • Ph.D. candidates were offered ,167
Electrical Engineer right out of college (8 years ago) was about $25/hr ($55K/year). EE with 8 years experience about $95K or $40-$50/hr. EE with 16 years experience around $160K. (Houston, TX)

A bachelor's degree in most areas can require between 120 to 128 college credits particular to a specific program of study. This would be based on a college or university that operates on a regular two semester academic year which is the most common. For institutions that operate on a tri-semester or quarter-semester it would be quite different. That being said, the Bachelor's degree - in most cases - is designed as a four year program of study, provided the student is full-time and follows their chosen program of study as prescribed by the college or university, and also provided the individual does not require prerequisite or developmental coursework as a result of basic skills testing. The minimum credit load for a full-time student is no less than 12 credits per semester. However, to complete the degree within the four years, a credit load of approximately 15 to 18 credits is recommended. For individuals who work or who have other responsibilities that would prohibit them from attending full-time, completion of the degree may take twice as long. Still, some of this time can be cut down by attending summer sessions and/or interim sessions. In addition, the bachelors and associate degrees are referred to as undergraduate degrees while the masters and doctorate degrees referred to as graduate degrees.

While not all programs of study require a basic computer course, it would be to your advantage to make sure you have the necessary computer skills. Many jobs will require that the employee is computer literate. In addition, in this day of technology it is almost a necessity for your research, curriculum assignments, as well as your personal life activities in many areas. I would advise you keep up with the times so you are not left behind. Make sure you acquire the appropriate computer skills. It is not hard, and the benefits are many.

The whole world has become a network of computers, like having a gigantic web connecting the whole earth. thus the world has been made a global village through the use of computers and the internet. therefore it is essential for everone to have at least a basic knowledge of computers in order to survive in todays and futures developing world.

While people with a Ph.D. in Computer Science can work in any standard computer science related job, it seems that they tend to be more research-oriented. Theoretical research institutes are likely to employ people with advanced degrees such as a Ph.D.

International Business Machines

Provides added incentive and motivation to find another employer.

to initialise the chip in microprocessor....that is for which purpose we are going to use it......

You name it, you can get it. Everything from office furniture, to staples. Staples is also a great place to watch for Black Friday deals after Thanksgiving. Computers and printers are often marked down %50 during this period.

the contemporary computer science focused more on dealing with the scalable information. For example: how to retrieve the information(google,yahoo), how to mining the information(ERP, data mining techonogy).

whereas, the traditional computer science pay more attention to the performance of the computer. For example, how to enlarge the memory capacity, how to make the computer smaller

A device, such as a keyboard, used to enter information into a computer.

What computer technicians need are as follows.

1. A collection of software. That would include operating systems, drivers, utilities, repair tools, memory testers, video testers, spyware removers, antivirus software, cleaner software, registry tools, etc.

2. Basic hand tools. Screwdrivers are needed to open the case and change components. Sometimes special screwdrivers are needed like security screwdrivers and torx drivers. A magnetic Phillips screwdriver comes in handy for motherboard screws. Forceps and tweezers are handy.

3. Basic electronics supplies. A soldering iron and 60-40 rosin core solder is good. Sometimes you might want to repair a power supply unit, such as if the fan is defective, unless it has an active warranty and shipping it off is a better option. Ground straps and antistatic mats are good to have. Chip pullers are only necessary for older PCs.

There are also optional tools and equipment that would help, but are not necessary.

1. Molex tools and parts. These are for repairing power supply plugs. There may be smaller varieties for the front panel connectors.

2. Hardware-based memory testers. These are boxes that are just for testing memory. You might be able to use them with a PC, but most will work alone. You would have to have all the correct adapters/jigs for each type of memory you plan to use which is compatible with the tester.

Keyboards, mice, printers, and monitors are four examples

Acer laptops range from 250 USD to 600 USD depending on the screen size, processing speed, and other computer specs. Many Acer desktop computers are right around 380 USD, although their gaming computers can be as much as 1200 USD.

There are several ways to underline a word when typing on a computer using a Word program. First, make sure your cursor is on the word you want to underline, or highlight the word or sentence you want to underline. If you are using Microsoft Word, you can go to the Format tab at the top of the program, choose Font from the drop-down list, then choose Underline. If you have the toolbar at the top with a button that has a "U" on it, you can press that and it will underline for you. Or, you can press Ctrl and the "u" key at the same time and it will underline for you. Most word processing programs have one of these options available for you to underline a word or sentence. These same instructions apply also if you want to bold a word or italicize a word.

Just fyi, to underline my instructions in this post, I highlighted what I wanted to underline and pressed the Ctrl button and the "u" button at the same time. Hope this answer helps you!
