Difference between twisted pair cables and fibre optic cables?

1. Unless you go to proprietory fibre, both can go to 1000Mb/s, so neither has a great speed advantate.

2. Wired is much cheaper. It's not the fibre that's expensive, but the terminations and the adapters.

3. Fibre can do much longer distances. Basic multimode 500 m. Monomode many kilometres. In theory wired is limited to 100 m. In practice you can get reliable connection at 100 Mb/s with up to 200 m. For 1000 MB/s, about 150m is the norm.

4. Fibre requires no electrical connection. So there are no problems about the earth potential being different in different buildings. In many practical situations, this isn't a major problem.

5. Lightening strikes on the ground can, in theory, damage switches connected with cables. In practice, over 8 years of plenty of lightening storms connecting separated buildings in a school site of 5 acres we have had no lightening problems.

How many bps in one GB?

In fact, your question doens't make sense. MBPS is megabytes per second. This is the transfer speek, in case of copying of files / downloading files. Remeber 1024 KB = 1 MB ; 1024 MB = 1 GB ; 1024 GB = 1 TB Regards, Akshit Soota (akshitsoota@yahoo.com)

How many GB are in 10000 MB?

There are 1000MB in 1GB, therefore, there 100MB is .10GB or in other words, there is .10 (one tenth) of a GB in 100MB.

there are 0.1 GB in 100 MB

This is not fully correct.

There is not 1000MB in 1 GB.

There is however 1024 megabytes in one GB.

100 / 1024 = .09765625

Answer is .09765625 GB

What is the difference between contemporary computer science and traditional computer science?

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

What is a monolithic kernel and a microkernel?

The kernel is the heart of an operating system.

The kernel internally contains many components, such as a memory manager, scheduler, numerous device drivers, a file system, and so on. When an operating system is being written, there are numerous design philosophies which the designers can adopt. At one extreme is the monolithic kernel, in which all of the components mentioned above, and many others, are all lumped into a single operating system file. At the other extreme is the microkernel, where only the bare minimum is put into the kernel file, and every thing else is put into separate programs, which the microkernel loads and runs at boot time.

In practice, the design of most operating systems lies somewhere in between those two extremes, although they generally tend to be closer to a monolithic kernel than a microkernel. But, like everything else in life, the microkernel has its true believers.

Other Answer:

In monolithic operating system all services are provided in the operating system kernel itself. In my own understanding, monolithic operating system is one big program. Being 'one big program' all the services are associated with one another. This is prone to system crashes, because, if one particular function fails, the entire system will be brought to halt. In regards to resource management, it is difficult for the programmer to debug or implement the system. The only advantages of being monolithic are it deals with resource management rapidly. An example of a monolithic operating system will be the UNIX and MS-DOS. In microkernel operating system, processes are divided and stored in a different server. This key concept of the microkernel operating system is to keep the OS kernel small with basic and minimum process. Other services are stored in a different server. They communicate, via a communication channel

What cache memory is designed inside the CPU?

L1 and L2; Many years ago L1 was the only cache memory integrated into the CPU (processor) and L2 had to be added to the motherboard. Currently (as of year 2013), CPUs implement both L1 and L2 cache in the casing of the processor. Thus, processors (CPUs) ship with amounts of L2 cache independent for each processor core.

What is GHz and MHz?

MHz stands for Mega Hertz.

Hertz or Hz is unit for frequency and is represented by inverse of time unit i.e. second(-1) i.e. 1/second or per second.

Frequency = 1/ time period in seconds

1MHz is 10^6 or 1000000 Hz.

Difference between telephone network and internet?
