Role of computers in Education
Considering the use of computer technology is almost every sphere of life, it is important for everyone to have at least the basic knowledge of using computers. Let's look at what role computer technology plays in the education sector.
Computers in Education
Computer technology has had a deep impact on the education sector. Thanks to computers, imparting education has become easier and much more interesting than before. Owing to memory capacities of computers, large chunks of data can be stored in them. They enable quick processing of data with very less or no chances of errors in processing. Networked computers aid quick communication and enable web access. Storing documents on computers in the form of soft copies instead of hard ones, helps save paper. The advantages of computers in education primarily include:
Storage of information
Quick data processing
Audio-visual aids in teaching
Better presentation of information
Access to the Internet
Quick communication between students, teachers and parents
Computer teaching plays a key role in the modern education system. Students find it easier to refer to the Internet than searching for information in fat books. The process of learning has gone beyond learning from prescribed textbooks. Internet is a much larger and easier-to-access storehouse of information. When it comes to storing retrieved information, it is easier done on computers than maintaining hand-written notes.
Computers are a brilliant aid in teaching.
Computers have given impetus to distance education.
Computer software help better presentation of information.
Computers enable access to the Internet which has information on literally everything.
Computer, hard drives and storage devices are an excellent way to store data.
Integrated learning systems
Integrated learning systems are hardware/software solutions designed to deliver instructional content. The effective delivery of that content is measured, monitored, and maintained with an array of assessment and management tools that may also be part of that system. Integrated learning systems are generally associated with educational/academic environments, but are also deployed within private industry, for example, as a way to introduce employees to new, mission critical systems and software applications.
As opposed to static online help or even animated tutorials, integrated learning systems are highly interactive and are designed to provide feedback as to progress and grasp of the subject matter at hand. Built-in tools further allow executive management or instructors and trainers to monitor and measure a student's progress.
Purchasing large and complex systems directly affect how organizations conduct business, as they require significant investments in time, money, and employee training. Additionally, organizations must correctly choose a solution that not only satisfies current needs but also supports future growth.
Software selection
Software solutions must be scalable to support ever increasing volumes and complexity of data from business growth. This makes the software selection process critical to laying the groundwork for a successful implementation for the long term. Spending the time to do it right the first time can save time, money, and increase employee satisfaction.

Computer Hardware
Computers have two main parts: hardware and software
Like piano (hardware) and music (software)
Computer hardware
The computer is an amazingly useful general-purpose technology, to the point that now cameras, phones, thermostats, and more are all now little computers. This section will introduce major parts and themes of how computer hardware works. "Hardware" refers the physical parts of the computer, and "software" refers to the code that runs on the computer.
Chips and Transistors
Transistor - vital electronic building block
-Transistors are "solid state" - no moving parts
-One of the most important inventions in history
-"Switch" that we can turn on/off with an electric signal
Silicon chip - fingernail sized piece of silicon
Microscopic transistors are etched onto silicon chips
Chips can contain billions of transistors
Chips are packaged in plastic, with little metal legs
e.g. CPU chips, memory chips, flash chips
Silicon (metalloid) vs. Silicone (soft substance on cooking utensils)
Here is a silicon chip inside its plastic package. I pulled this out of the e-waste pile at the Stanford CS building, so it's probably kind of old. This is a small chip with just a few "pins" of electrical connection. Later we'll see a bigger chip with hundreds of pins.
Computer Hardware - CPU, RAM, and persistent storage
Now let's talk about the three major parts that make up a computer -- CPU, RAM, and Persistent Storage. These three are found in all computers: laptops, smartphones, and tablets.

Computer Facilities
There are computer facilities conveniently located in several buildings across campus. Here students can access MS Office, the internet, print services, as well as specialized applications required for various courses.

Printing
In order to print in the labs, you must first prepay for printing. We call money on your print account print credits. Students may purchase print credits from the Lab Assistant in Seton 316 or at the Helpdesk in the Information Commons. Print credits purchased in either location can be used in any of the general use student labs (Seton 315, 316, Evaristus 136, EMF127C and Information Commons). More Info:
Food and Drink in Labs
Food and drinks can cause equipment failure if introduced into the electronic components of a computer; therefore, they are forbidden in all computer labs. Offenders may be asked to leave the lab, and lab privileges may be revoked.
Virus Checking
A virus is a program designed to corrupt other programs. The impact of viruses can range from making your computer crash to deleting important files, possibly doing enough damage so that the computer is inoperable. All lab computers are protected by Trend Micro Antivirus.
