IT111 - Lab Exercise (Aug.12)

1. Students use a search engine to find information about who invented the microprocessor.
2. Students investigate the computer’s power management settings and create a report on what they discover.
3. Create a list of components and features that the student should consider when purchasing a computer. They then explain why they made these selections.
4. Students are  to prepare a report on solid-state storage and how it works.
5. Students are to investigate teleconferencing technology.
6. Students are to compare solid-state storage to magnetic and optical storage media. They are to express an opinion indicating whether they think solid-state storage will replace the other types of storage.

answer:


1.Ted Hoff saved his own life, sort of.
Deep inside this 73-year-old lies a microprocessor - a tiny computer that controls his pacemaker and, in turn, his heart.
Microprocessors were invented by - Ted Hoff, along with a handful of visionary colleagues working at a young Silicon Valley start-up called Intel.
This curious quirk of fate is not lost on Ted.
"It's a nice feeling," he says.

2.*Enforce Power Management Settings in your Organization with Group Policy.
   With Microsoft System Center Configuration Manager 2007, you can easily monitor and capture the            configuration information of servers, desktops, and laptops across your network..    
   *Conserving Energy with Group Policy.
Power management on a single computer can save energy and money. When you enforce your power management strategy on systems throughout your entire organization, obviously the savings can be far more substantial.

3.*brand
             -to sure your coputer is original and not fake.
  
   *GB of computer
             -to sure thst you can save all your documents.

4.SST-(solid- stage storage)
          is a data storage device that uses solid-state memory to store persistent data with the intention of providing access in the same manner of a traditional block i/o hard disk drive.

5.teleconferencing technology.      is a telephone meeting among two or more participants involving technology more sophisticated than a simple two-way phone connection.

6.other types of storage
           -Hard Disk Drive 
           -Compact Disk (CD) 
           -Digital Versatile Disk (DVD) 
           -USB Drive (Pen Drive) 
           -Blu-Ray Disk

what is URL?

URL stands for Uniform Resource Locator and is a reference or address to a resource on the Internet.

Uniform Resource Locators are also called as Uniform Resource Identifiers. They are short strings that identify resources on the web that are documents, images, downloadable files, services, electronic mailboxes, and other resources. They make resources available under a variety of naming schemes and access methods such as HTTP, FTP, and Internet mail addressable in the same simple way.

what is desktop?

 is a personal computer (PC) in a form intended for regular use at a single location, as opposed to a mobile laptop or portable computer

Desktop and tower computers are two different styles of computer case that use desk space in varying ways. Desktop computers are designed to lay flat on the desk, while towers stand upright.

Prior to the widespread use of microprocessors, a computer that could fit on a desk was considered remarkably small. "Desktop" indicates a horizontally-oriented computer case usually intended to have the display screen placed on top to save space on the desktop. Most modern desktop computers have separate screens and keyboards.

Tower cases are sometimes incorrectly called desktop computers as some will locate them on a desk instead of on the floor under the desk. Cases intended for home theater PC systems are usually considered to be desktop cases in both senses, regardless of orientation and placement.

what is computer?

is in a specific, contemporary sense. Personal computers are found in most aspects of daily life, and for some it is hard to even imagine a world without them. But the term computer means more than simply the Macs and PCs we are familiar with. A computer is, at its most basic, a machine which can take instructions, and perform computations based on those instructions.

It is the ability to take instructions — often known as programs in the parlance of computers — and execute them, that distinguishes a computer from a mechanical calculator. While both are able to make computations, a calculator responds simply to immediate input. In fact, most modern calculators are actually computers, with a number of pre-installed programs to help aid in complex tasks.
