INFORMATION AND COMMUNICATION TECHNOLOGY
ICT LEVEL ONE & TWO
SUBJECT: COMPUTER SYSTEM FOR BUSINESS
MAY/JUNE 2021
INSTRUCTIONS: Answer all questions in SECTION A and SECTION B.
You are advised not to spend more than 1 hour on SECTION A.
SECTION A
Answer All Questions
The main characteristics of a computer include:
- Speed
- Accuracy
- Automation
- Storage Capacity
- Versatility
- Reliability
Internal Components:
- Central Processing Unit (CPU)
- Random Access Memory (RAM)
- Motherboard
External Components:
- Monitor
- Keyboard
DOS Command: A DOS command is a command used in the DOS (Disk Operating System) command line interface to perform specific tasks such as file manipulation, program execution, and system control.
ROM: Read-Only Memory
BIOS: Basic Input/Output System
Deadlock: Deadlock is a situation in computer systems where two or more processes are unable to proceed because each is waiting for one of the others to release a resource.
Causes of Deadlock:
- Mutual Exclusion: At least one resource must be held in a non-sharable mode.
- Hold and Wait: A process holding at least one resource is waiting to acquire additional resources held by other processes.
The CPU (Central Processing Unit) components include:
- Arithmetic Logic Unit (ALU)
- Control Unit (CU)
- Registers
Primary Storage: Also known as main memory, it is the storage that is directly accessible by the CPU, such as RAM.
Secondary Storage: Also known as external memory, it is not directly accessible by the CPU and is used to store data long-term, such as hard drives and SSDs.
Methods of Booting:
- Cold Booting: Starting a computer from a powered-down state.
- Warm Booting: Restarting a computer without turning off the power.
Preferred Method: Cold booting is preferred when a computer goes into a deadlock.
A bus in the CPU is a communication system that transfers data between components inside a computer or between computers. It connects all the internal components of a computer, such as the CPU and memory, and enables them to communicate with each other.
Cyber Fraud: Cyber fraud involves the use of internet services or software with internet access to defraud victims or to otherwise take advantage of them. Examples include phishing, online scams, and identity theft.
Types of Disk Drives:
- Hard Disk Drive (HDD)
- Solid State Drive (SSD)
FORMAT Command: The FORMAT command is used to prepare a storage device, such as a hard drive, solid-state drive, or USB flash drive, for use by an operating system. It erases all data on the device and sets up a file system structure to organize and manage data storage.
DOS: DOS stands for Disk Operating System. It refers to a family of operating systems that were prevalent in the 1980s and early 1990s, such as MS-DOS (Microsoft Disk Operating System).
SECTION B
Answer All Questions
Fragmentation: Fragmentation refers to the condition of a storage device in which files are divided into pieces scattered around the device. This happens when a file is broken up into smaller parts that are stored in non-contiguous sectors on a disk.
Importance of Fragmentation:
- Improves file retrieval speed by reducing the time it takes to access files.
- Enhances the overall performance and efficiency of the storage system.
Fifth Generation Computers: Fifth generation computers are based on artificial intelligence (AI) technologies, which include robotics, natural language processing, and neural networks. These computers are designed to understand natural language and can learn and adapt to new situations. They use massively parallel processing and superconductors to increase computational speed and efficiency.
Mouse: A mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the movement of a pointer on a display, allowing the user to control the graphical user interface.
Joystick: A joystick is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. Joysticks are commonly used to control video games and machines such as cranes, trucks, and underwater unmanned vehicles.
Touch screen: A touch screen is an input device that allows users to interact with a computer by touching the screen directly. It can detect the location and movement of touches within the display area, enabling gestures and taps to control the device.
Assembler: An assembler is a software tool that translates assembly language code, which is a low-level human-readable programming language, into machine code, which is binary instructions that a computer's CPU can execute directly.
Interpreter: An interpreter is a type of software that executes code directly, translating it into machine language one line at a time. This allows for immediate execution of high-level programming languages but may result in slower performance compared to compiled code.
Compiler: A compiler is a software tool that translates high-level programming language code into machine code in its entirety before execution. This machine code can then be run directly by the computer's CPU, typically resulting in faster performance.
Bit: A bit (short for binary digit) is the smallest unit of data in a computer, representing a single binary value of either 0 or 1.
Byte: A byte consists of 8 bits and is the standard unit of data used to represent a character such as a letter, number, or symbol in a computer.
Binary Coded Decimal (BCD): BCD is a class of binary encodings of decimal numbers where each digit is represented by its own binary sequence. For example, the decimal number 12 is represented in BCD as 0001 0010.
Operating System: An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs.
Functions of an Operating System:
- Process Management: It manages processes in the system, including the scheduling, execution, and termination of processes.
- Memory Management: It handles the allocation and deallocation of memory space to various programs and ensures efficient memory utilization.
Applications of Computers:
a. Business: Computers are used in business for various purposes, including data management, financial analysis, communication, and automation of routine tasks. They improve efficiency, accuracy, and productivity.
b. Marketing: Computers are used in marketing to analyze market trends, manage customer relationships, create digital marketing campaigns, and conduct market research.
c. Government: Computers are utilized in government operations for record-keeping, data management, public administration, communication, and service delivery. They enhance transparency, efficiency, and public service delivery.
Word Processing: Word processing refers to the creation, editing, formatting, and printing of documents using a computer and software designed for these tasks, such as Microsoft Word or Google Docs.
Advantages of Word Processing:
- Editing Flexibility: Word processors allow for easy editing and formatting of text, including the ability to make changes, insert or delete content, and rearrange text without the need for retyping the entire document.
- Spell Check and Grammar Check: Word processors often include tools to automatically check and correct spelling and grammar errors, enhancing the accuracy and professionalism of documents.
- Templates and Styles: Word processors offer a variety of templates and styles that simplify the creation of professional-looking documents, such as resumes, reports, and letters, with consistent formatting and design.
