TG1.1 Components of a Computer System
Computer hardware is composed of the following components: central processing unit (CPU), primary storage, secondary storage, input devices, output devices, and communication devices. Communication devices are covered in detail in Tech Guide 4.
The input devices accept data and instructions and convert them to a form that the computer can understand. The output devices present data in a form people can understand. The CPU manipulates the data and controls the tasks done by the other components. Primary storage (internal storage that is part of the CPU) temporarily stores data and program instructions during processing. Secondary storage (external storage such as flash drives) stores data and programs that have been saved for future use. Communication devices manage the flow of data from public networks (e.g., Internet, intranets) to the CPU, and from the CPU to networks. A schematic view of a computer system is shown in Figure TG1.1.
REPRESENTING DATA, PICTURES, TIME, AND SIZE IN A COMPUTER
ASCII. Computers are based on integrated circuits (chips), each of which includes millions of sub-miniature transistors that are interconnected on a small (less than l-inch-square) chip area. Each transistor can be in either an “on” or an “off” position.
The “on-off” states of the transistors are used to establish a binary 1 or 0 for storing one binary digit, or bit. A fixed number of bits representing specific characters—letters, numbers, and special symbols—is known as a byte, usually 8 bits. Because a bit has only two states, 0 or 1, the bits comprising a byte can represent any of 28, or 256, unique characters.
The character that the byte...

Hemo Tech

...Hemo Tech seems to have covered all their bases, assuming that the consumer decides to proceed into a contractual agreement for their equipment and services. Hemo Tech did not include training/ in-service as a deliverable. It is considered a deliverable because it is a service. Most medical equipment vendors readily offer this service as an incentive to purchasing their equipment. It is very necessary because this is the best way to fully ensure the user knows how to use it. The instruction manual is a great guide, but hands-on training is preferred when dealing with medical vendors. Part II Hemo Tech only sells it systems and installations as bundle, it does not sell it items individually. Hemo Tech does not have VSOE for selling prices of its equipment. Hemo Tech does not have TPE for selling prices, neither, due to the more advanced technology of their equipment compared to their competitors. Hemo Tech uses best estimations to determine selling prices by considering the cost taken to manufacture and develop the deliverables. In regards to the discounts on future services, Hemo Tech has VSOE for selling prices, because the supplies are sold separately at a consistent price. They, also, have TPE for selling price for their supplies because the items other vendors have supplies that are interchangeable to their supplies. Only issue is Hemo Tech supplies offers more enhanced feature that reduces extraction and storage time for samples....

Tech Support

...Running head: BASICS OF COMPUTER ONLINE TECH SUPPORT The Basics of Online Tech Support Steven T. Craig TUI University ITM 501 The Basics Of Online Tech Support In this paper I will share my experiences of On-Line Tech Support and the adventures of getting problems solved through the use of the Internet. First, I selected the main purpose for my search of on-line tech support. Since I was having problems with my computer with its daily operations, I felt that there was nowhere to turn but to reboot the computer and start from scratch. However, I was not to keen on the idea of erasing all my data and starting over and thought that perhaps there was another way to fix my issues. I used the on-line tech support web site www.Help.com. After searching the Internet for an interesting or catchy home page of Internet tech support, I stumbled upon help.com. I read the intro page and look under some of the discussions and decided to enter the domain and ask my help question. Which was, “ how do you erase your computers data and start all over?” After being prompted to sign up for the account and agreeing to the user agreement options. I started off by reading previous post, for ideas of answers and posted dialogue that was being shared. Unfortunately my question was not asked previous and I had to venture out on my own to request the answer....
