i. Micro computer: is a small, relatively inexpensive computer with a microprocessor as its central processing unit (CPU). Designed for individual use, a microcomputer is smaller than a mainframe or a minicomputer
ii. Computer Monitor: A computer monitor is an output device that displays information in pictorial form.
iii. Computer keyboard: A computer keyboard is an input device in a typewriter-style form which uses an arrangement of buttons or keys.
A computer network is a group of computer systems and other computing hardware devices that are linked together through communication channels to facilitate communication and resource-sharing among a wide range of users.
– CPU is just a small part of system unit while a system unit operates the whole computer.
– CPU does not contain a power supply unit while a system unit provide supply to the whole computer.
– CPU contains microprocessor which process data while system unit processes and controls the whole of your computer.
– System unit include CPU hence it is a small part of system unit.
– The heart of the System unit is CPU, so without CPU the system unit cannot work.

– and then choose the location and style you want.
Copy and paste are commands in a computer user interface and are one method of transferring data from one location to another. Unlike cut and paste, which moves the contents to a new location, copy and paste creates a duplicate in the new location. Copy and paste enables simple data replication.
• Microsoft Excel
• Google Sheets
• iWork Numbers – Apple Office Suite.
1. Constants: are Values or Strings directly entered in to a formula
2. References: are used to refer to a cell or range in a Excel.
3. Functions: are inbuilt (block of) codes that performs a certain calculation in a particular order.
4. Operators: are special symbols that perform specific operations between operands, and then return a result.

i. A master file: is the main file that contains relatively permanent records about particular items or entries. For example a customer file will contain details of a customer such as customer ID, name and contact address.
ii. Transaction (movement) file: A transaction file is used to hold data during transaction processing. The file is later used to update the master file and audit daily, weekly or monthly transactions. For example in a busy supermarket, daily sales are recorded on a transaction file and later used to update the stock file.

– Background can be changed using the slide master
– Color and fonts, and positioning of all slides is done using the Slide Master.
Spline: Creates a smooth curve that passes through or near a set of fit points, or that is defined by the vertices in a control frame.
Trim: This projects the cutting edges and the objects to be trimmed onto the XY plane of the current user coordinate system (UCS).
Purge: Removes unused items, such as block definitions and layers, from the drawing.
Fit: It enables objects to be of the right shape and size for.
1. The Command Prompt:
Execute a command by entering the full command name or command alias at the command prompt and pressing ENTER or SPACEBAR. When Dynamic Input is on and is set to display dynamic prompts, you can enter many commands in tooltips that are displayed near the cursor
2. Quick Access Toolbar:
Store commands that you frequently access in AutoCAD. By default, you can access New, Open, Save, Plot, Undo, and Redo from the Quick Access toolbar. Add commands to the Quick Access toolbar using the shortcut menus of all commands on the ribbon, menu browser, and toolbars
F2 Expanded history Displays an expanded command history in the Command window.
F3 Object snap Turns object snap on and off.
Mirror: The Mirror command creates a reverse copy of an object in AutoCAD. After you select
some objects, AutoCAD prompts you to select two points that define a line about which the objects will be mirrored.
Grid: The grid is a rectangular pattern of lines or dots that covers the entire XY plane of the user coordinate system (UCS). The grid helps you align objects and visualize the distances between them. The grid is not plotted.
Copy: It creates duplicates of an objects and it leaves a copy of the original object in its position.
It works as it would in other windows application, and feel free to use the Ctrl+C and Ctrl+V to copy and paste objects in AutoCAD.
Chamfer: It creates a chamfer edge on an objects. A bevel or chamfer can be defined by selecting two objects of the same or different object types: lines, polylines, rays, and xlines. If the two selected objects are on the same layer, the line defined is created on that layer.
