– Random Access Memory (RAM)
– Read Only Memory (ROM)
o It is the main memory and allows you to temporarily
store commands and data.
o If a computer has more RAM, it can solve problems
and process information faster.
o This memory is permanent. The information there
was put there when the computer was made. The
computer needs the information in it’s ROM memory
in order to function
o It is the memory that retains its contents even after
the computer is turned off.
Storage Devices
• Hard Disk
• Use to store data and software
• Flash Drive
• Use to store data, data transportation
• CD-ROM
• Use to store data, data transportation
• and installation of software.
How Computer Memory Is Measured
Bit
o All computers work on a binary numbering system, i.e.
they process data in one's or zero's. This 1 or 0 level of
storage is called a bit.
Byte
o A byte consists of eight bits.
Kilobyte
o A kilobyte (KB) consists of 1024 bytes.
Megabyte
o A megabyte (MB) consists of 1024 kilobytes.
Gigabyte

Editor's Notes

  1. Computers play a major role in our daily lives. They are used in industries, schools, government offices, and shops. You can use computers to communicate with your family and friends, create a household budget, book travel and movie tickets, or manage your business. In business and industry, you use computers to maintain accounts, create personnel records, track inventory, prepare presentations and reports, manage projects, and communicate by e-mail. You can use computers to design any type of publication ranging from simple newsletters to fashion magazines, marketing materials, books, or newspapers. In the field of education, trainers can use computers to deliver training through audio-visual learning aids, maintain student records to track performance, search for information on different topics, and create or submit assignments. In government organizations, you use computers to organize information by storing and updating records. Computers are also used for providing services to citizens. For example, you can view information on current policies and government issues on a computer. In the field of medicine, doctors use computers to review medical records of patients. Doctors also use computers to find information about the latest drugs available to treat a disease. Doctors can also use computer technology to discuss and share information about various diseases. You can use computers to view the details of your bank account. Traders use computer technology to get instant information on stock markets, to trade stocks, and to manage investments. Scientists use computers for scientific research, and to gather and analyze information. For example, they use computers to view images from space and to publish information on their recent research. You can also use computers to create drawings and paintings. Photographers use computers to edit and enhance pictures. Writers use computers to write content for their books and to also create illustrations. By using computers, writers can make changes in the content easily and save a lot of time. In the field of entertainment, you can use computers to listen to music, watch movies, store and print photographs, send greetings, and play games.
  2. The operating system allows you to use the advanced features of a modern computer without having to learn all the details of how the hardware works The link between the hardware and you, the user Makes the computer easy to use without having to understand bits and bytes!

  6. Alphanumeric Keys: These keys are used for entering letters and numbers. Special Keys: Keys such as Control (CTRL), SHIFT, SPACEBAR, ALT, CAPS LOCK, and TAB are special keys. These special keys perform special functions depending on when and where they are used. Punctuation Keys: Punctuation keys include keys for punctuation marks, such as colon (:), semicolon (;), question mark (?), single quotation marks (‘ ’), and double quotation marks (“ ”). Command Keys: Keys such as INSERT (INS), DELETE (DEL), and BACKSPACE are command keys. You use these keys to insert and delete text and objects. You can turn the INSERT key either ON or OFF. When turned ON, the INSERT key helps you overwrite characters to the right of the insertion point. When turned OFF, the INSERT key helps you enter text or characters to the right of the insertion point, without overwriting this text or characters. An insertion point is the blinking vertical line that indicates the location at which the inserted text appears. The DELETE key is used to remove typed text, characters, and other objects on the right side of the insertion point. The BACKSPACE key is used to remove typed text, characters, and other objects on the left side of the insertion point.
  7. A mouse is a small device that you can use to move, select, and open items displayed on your monitor. The mouse is usually kept on the desk next to the keyboard. Most mouse devices have at least two buttons, left and right. Most of the actions are performed by clicking the left button. The right button is used for specific functions. Some advanced types of mouse devices provide additional buttons to speed up common tasks, such as scrolling text. As you move the mouse on your desk, a pointer moves correspondingly on your screen. The mouse allows you to select an item on the screen. As you move the pointer over different areas of the screen, the items or the pointer change. These changes indicate that you can click an item to open it, or see more of its options. You can open an item by moving the pointer to it, and clicking the left mouse button twice. In a document, you can use the mouse to select a position to start typing. You need to position the pointer in the document, click where you want to insert text, and then use your keyboard to begin typing. To move an item, you need to click it, and then holding the mouse button down, move the item to a different location. After you move the item to the new location, you release the mouse button. The right button on the mouse is used to display a menu. The options on this menu include the most common tasks, such as copying text from one location and pasting it to another location. These are called context-sensitive menus. These menus help you complete tasks quickly. Most mouse devices also have a wheel that help you to scroll through documents or pages. To scroll, place your finger on the wheel and roll it back and forth. This moves the document up and down.
