What is Information Technology

• Information Technology (IT) is a term used to describe several things: the task of gathering data and

processing it into information, the ability to disseminate information using technology, the

technology itself that permits these tasks, and the

collection of people who are in charge of maintaining the IT infrastructure (the computers, the networks, the operating system).

The Use of Information Technology

• IT is ubiquitous today. Nearly everyone on the planet uses some form of computing technology through cellular phones and tablets or home

Working with IT

1. Enjoy playing around with the computer—not just using it, but learning how it works, learning how to do things.

2. Enjoy learning on your own—liking the challenge of figuring things out, especially new things.

IT Law in Indonesia

• IT Law in Indonesia is regulated in Undang-Undang Republik Indonesia Nomor 11 Tahun 2008 Tentang Informasi dan Transaksi Elektronik (ITE).

• It has regulations for anything related to the use of IT such as: electronic signature, electronic

IT Infrastructure

• IT revolves around the computer. Your cell phone is a computer as is your Kindle. These are far less

powerful than desktop units, but they are computers nonetheless.

• There are computer components in your car and on the city streets that you drive. The building you

Computers

• A computer is an electronic, programmable device.

• To run a program, the device needs a processor [Central Processing Unit (CPU)], memory to store the program and data, input and output

CPU & Storage

• The main component of a computer is the processor.

• The pro essor’s role is to pro ess— that is, it executes the programs we run on the computer.

• Aside from the processor, computers need storage. There are two types of storage:

1. Short-Term Storage (Temporary)

• Short-term storage is most commonly random access memory (RAM)

• Modern computers typically have three forms of RAM:

• Dynamic RAM (what we typically call main memory),

• Static RAM (cache memory and registers)

Short and Long Term Storage on Desktop

• To run a program, we need to load that program into a storage space that responds quickly.

• Long-term storage is far slower than RAM, so

unless you are willing to have a very slow computer, you need short-term storage.

• Short-term storage is far more limited in capacity and the programs we run tend to be very large. We also often have very large data files (music files,

Volatile & Non-Volatile

• The term volatile, when describing memory, indicates whether the type of memory can retain its contents when the power supply has been shut off.

• Main memory (DRAM) and cache/register memory (SRAM) are volatile forms of memory.

• Once you turn the power off, the contents are lost. This is why, when you turn on your computer, memory is initially

Software

• A program, also known as software (to differentiate it from the physical components of the computer, the hardware), is a list of instructions that detail to the computer what to do.

• There are many forms of software. Generally, it may be divided into two categories:

1. System Software (the operating system)

2. Application Software (programs that we run to accomplish our tasks)

User

• User initiates the processes on the computer and interact with the programs while they run. This interactivity is done through the I/O devices.

• Today, we are so used to interactivity that we probably cannot imagine using computers without it.
