Terminology Relate To Computer?
Assembler :
It translates the source program in assembly language into machine code.
Coding :
The proces of writing out computer Instruction is known as "coding".
Compiler :
It is a program that translate the user source program written in high level language to an object code ready for execution.
Computer virus :
It is computer that can replicate itself and spread from one computer to another. The virus stays active in the background and infects new hosts when those files are based on their behaviour when they are executed.
- Nonresident viruses
- Resident viruses
Nonresident viruses immediately search for other hosts that can be infected, infect those targets, and finally transfer control to the application program they infected. Resident viruses do not search for hosts when they are started. Instead, a resident virus loads itself into memory on execution and transfers control to the host program. Non resident viruses can be thought of as consisting of finder module and replication module. The finder module is responsible for finding new files to infect.
Computer Worm :
A computer worm can exploit security vulnerabilities to spread itself automatically to other computer through networks.
Debugger :
In a computer a bug is a coding error which causes wrong result. The process of searching and correcting bugs in a program is called "debugger".
File :
A saved document is referred to as a 'File'. i.e a file is a collection of information saved as a unit.
Folder :
You organize files by storing them in folder.
Hardware :
All the electrical and electronic components used to assemble a computer are called as 'Hardware'. Examples are keyboard, mouse, VDU, CPU and so on.
1) Key board
It just like a type-writer which contains key to feed the data information into the computer. It is attached with the system unit through a cord. Standard and IBM keyboard have 83 keys while enhanced keyboard has 104 keys. It communicates user to the computer. A computer's keyboard has many more keys that does several more function.
2) Monitor
This is the most popular input/output device looks like a small TV and shows you what is going on. It has two cords, one for power and other for connecting to the system unit. When commands are given to computer through the keyboard are displayed on monitor.
3) Mouse
It is an input device and is used to point and select items on your computer screen I.e. for controlling the movement of the cursor on the computer screen. By sliding the mouse on a flat surface the user clicks the mouse to select the items. A single cord present on the back side of system unit used to connect it. Today's cordless mouse are available in the markets. The left and the right click have different functions depending on the software being in use.
4) Scanner
It is input device that scans photos, graphs, diagrams or any handwritten matters and transfers to the computer in digital form.
5) Printer
It is the primary output device used to prepare permanent documents in readable form, such readable document are called 'hard copy'.
6) Speaker
It is an output device, often it is used for entertainment. It is connected to the sound cord of the system unit. The output as a sound can be heard in the speaker.
Interpreter :
It is a program that translates the user source program written in high level language to an object code.
Malware :
It include computer viruses, computer worms, trojan horses, keyloggers, spyware, dishonest adware, ransomeware, most rootkits and other malicious software.
Operating system :
It provide interface between hardware and software.
Output Devices :
The output device is the counterparts of the input where the transfer of Information and data is made from the computer to the external unit. The most common example of output devices are monitor and printer.
Example :
1) Monitor
This is the most popular input/output device looks like a small TV and shows you what is going on. It has two cords, one for power and other for connecting to the system unit. When commands are given to computer through the keyboard are displayed on monitor.
2) Printer
It is the primary output device used to prepare permanent documents in readable form, such readable document are called 'hard copy'.
Programmer :
The person who writes and tests computer program is called a "programmer".
Software Privacy :
Copying computer program or software without the permission of its author is called "software privacy".
Trojan horse :
It is a program that appears harmless but hides malicious functions. Worms and trojan horses, like viruses, may harm a computer system's data or performance.
