These computers have huge storage capacity and have huge processing power. So the development cost for such big size computer is very huge and such kind of manufacturing can be done by big companies. You can see these mainframe computers in banking and financial sectors where millions of records have to be maintained on daily basis. Features of this machine will be about Processing Power, Performance Rate, Memory Capacity, Multiple Operating System, Availability, Clustering Technology, Reliability etc.

About Mainframe Computers

Mainframe computers have large number of CPU that have Greatest Processing Power. All these CPU’s are placed in a frame like structure. Due to large number of CPUs, Mainframe has huge memory capacity that is required to keep records of all the applications processed by it in different sectors. A mainframe computer is smart enough to share the workload among its processors and input/output device in order to reduce load on the computer. With the sharing of workload, processing ability gets faster resulting increase in performance. Mainframe computers have an ability to run different number of operating systems at the same time, so you can consider it as a collection of virtual machines. Mainframe computer works on centralized computing. It means that all the operations that have to be performed occur in the processor section and final result can be seen on the computer screen. Mainframe computer also support Time Sharing so that thousands of users can operate on the machine simultaneously with full efficiency. The best part of Mainframe computer is that it supports almost all kind of operating systems like Linux, UNIX and IBM operating system like Z/OS, Z/VM etc. This big machine is also known for its reliability as it gives high performance required for some operations that are based on the database.

Technicality of Mainframe Computers

Big industries need such system that can be available all the time with 100% throughput and Mainframe computer suits this need very well. Mainframe computer is always available to its users due to its great design that has collections of I/O channels, Power Supplies, Memory Buses and Memory Chips. Mainframe computer is serviceable. In other words, if any part of the CPU is needed, it can be replaced but for doing it, system operation has to be shut down for a while.

Apart from all these technical features, Mainframe computer also supports Maximum I/O connectivity. It has the capability of providing maximum number of I/O bandwidth and can manage a large number of users. So with overall discussion, it can be said that Mainframe system proves to be a good resource for complex business process as it can handle thousands of applications at the same time and has good processing speed. After going through the account above, you will not question ‘How does Mainframe Computer look like?’This large machine is highly in demand.

First of all, let me say something that I have never said in the previous articles where I have discussed about the Seagate hard drives; this is an eco friendly product, which has received the status of being a green product. In fact, if you look closely at the images presented in this article, you will see that this is indeed a green product. But let’s also read some information, not only look at the images.

The I/O data transfer rate is of 600 MB/s. The unrecoverable read errors are of 1 in more than 10 millions (in fact, this number is way bigger). The reliability of the hard drive is of 750000 hours. The annual failure rate is of 0.34% and the power requested by this device in order to work is of 12V. The average idle power is of 4.5W and the average operating power is of 5.8W. Once again I have to say that the information are taken directly from the site the manufacturer, so you have to trust them. I did not take the information from sites that sell this type of hard drives, but directly from the site of manufacturer, Seagate.com.

Let’s see what should be the environmental conditions and the ambient temperature in order to use this hard drive. It is considered that you can use the hard drive in harsh conditions, but I recommend to not try this. If you want to protect your computer and the information stored in your hard drive, you better not try to see if the computer runs okay in these conditions. The operating temperature is somewhere between 0°C – 60°C. You should not use your hard drive at temperatures lower than 0°C, neither at temperatures higher than 60°C. It is considered that the hard drive will be damaged if you will try to use it at -40°C or + 70°C. I believe that you can hardly breathe in those conditions, so I guess that you don’t have too much time for running the computer, as long as you want to keep breathing. The operating shocks after which this hard drive can still function is of 80 Gs for 2 ms. Also, another important thing related to the operating temperature, when you move from a location with a certain temperature to another location where you will find other temperature, make sure that the difference of temperatures between those two rooms is not higher than 20°C per hour.

Well in fact is not; think of the desktop computers that have even larger storage capacities, because their physical space provides them this possibility (they are larger) and they can reach to 2.5 TB. If you connect an external storage device, you are able to obtain a larger amount of space in the hard drive or solid-state drive.

But today, the necessities are not to create a bigger and bigger hard drive or SSD, but to allow the people who have computers to store their personal information in a safe way in the Cloud. It is considered that the Cloud is one of the best ways to store your personal and professional information. So, if you want to buy a portable computer, which at the same time to allow you the possibility of connecting it to the Internet and staying always updated to the news about your friends, today you can do this without too many worries that you don’t have the space of storing the information that you possess. If you want to be sure that your information is protected you can set a password to your hard drive or to your entire computer. This would be the same thing as entering the Cloud. When you download a program from the Internet or when you simply install the program in your computer, you have to be attentive to the size of the program, so that it can be ran by your computer and stored. You buy in vain a software program that comes in 10 GB if your free space is of only 8 GB, you will not be able to store that program. Plus, you have to take into consideration that the operating system requires some resources when it is ran.

Some of the sizes of the software programs are expressed in different ways of showing how big the size of the program is. For example, the size can be expressed in bits, in bytes, terabytes or petabytes. Luckily for you I have found the site, which is named t1shopper.com, and which allows you the possibility of transforming the size of the program into whatever you want. Of course you will not transform bits to bits, but bits to bytes or bytes to bits. It is like when you make a mathematical conversion, only that this one is applied in informatics.

Among the results that appeared in the list with results on Amazon, the first one is the Case Logic SNMB-15F 15.4 inch full-size Canvas messenger bag, that allows the storage of your laptop. This case is created by an authority in this domain of creating carrying cases for laptops (I’m talking about Case Logic), this is why probably the price of this bag is of $38.99. I am not saying that the case is expensive, I am only saying that I know a few people who will search for cheaper products online. If you ask me, I would buy such bag, if it would have another color, not black.

The next product presented in the list is another Case Logic product, namely the VNA-200-1616 inch laptop attache, also designed in black. The price of the this bag is of $20.97. The third product is created by the same manufacturer and I will not present it anymore, since I have presented 2 products created by the Case Logic company. But the next product is a surprise, it is created by Microsoft and it is an Edge Messenger Bag, created for the 17.3 inch laptops. It is black with orange elements. Then, we have an Oakley Men’s Checkpoint Computer Bag, that is sold on Amazon for $60. There are sellers who sell this product for $75 if you buy from them. If you allow me a suggestion, I would buy the bag that costs $60. By the way, I have seen that I did not present the price of the Microsoft bag, named earlier; the bag costs $34.99. There are no used Microsoft bags on Amazon right now.

Another important manufacture of carrying cases is Targus. With this one, I think I have named them all. I am sure that there are also other manufacturers who create exquisite laptop bags, but these are the ones present on Amazon. The price of the Targus CityLite Top-Loading case, created 46 inch laptops, that is grey with black, costs $30.57.

But I was wrong, this is not the name of the manufacturer, it is the name of a wood color.

For example, as you can see online there are many cherry corners computer desks, but this is the only combination between the words cherry corner and computer. It is a bit inappropriate to be interested in the color of the hard drive, unless it is an external hard drive. Because if it is and if you use already a cherry corner computer desk, as I have seen online, the situation is changed. But this should not be a problem, since there are many skins that you can attach to almost anything. I guess that you probably have heard of the skins created for computers or smartphones. Some of the skins manufacturers create large scans, that can be cut by the user in the form that the user wants. So if the user wants to use only 2 mm of a skin created for a laptop, he can cut that skin the way he wants. So we have solved the problem with the color of the external hard drive. If it will match the cherry corner computer desk, then the people who will enter your office or your room, where you perform your daily activities, will understand that you are a classy guy, with style. But be careful, because the cherry trees have more colors, depending on the moment when they are cut. A cherry tree that is cut when it is young will have a brighter color that a cherry tree that is cut in its late days.

So if you want to buy a computer storage that has the exact same color as the desk you’re using, then you have to take a sample of the wood with you, when you order the external hard drive. If you are not sure of the color, the color can be created by those who personalize such products for those who pay more. You can even choose this type of product as a gift for someone you love. You can even dress your own laptop in the same skin as the external hard drive; in this way your desk will seem like an elegant spot in the entire office.
