- Industry-Specific Software:Tailored to specific industries or professions, such as accounting software for accountants or design software for graphic designers.
Networking and Communication
Computer networks connect multiple computers and devices, enabling them to share resources and exchange information. They play a crucial role in modern communication, facilitating data transfer and seamless collaboration.
Network Topologies
Network topologies define the physical arrangement of devices within a network. Common topologies include:
-*Bus topology
Devices are connected to a single shared cable.
-*Star topology
Devices are connected to a central hub or switch.
-*Ring topology
Devices are connected in a closed loop, with each device passing data to the next.
Network Protocols
Network protocols establish rules and procedures for data transmission. They ensure that data is transmitted and received correctly. Key protocols include:
-*TCP/IP
The primary protocol suite used on the Internet, providing reliable data delivery.
-*HTTP
The protocol used to transfer web pages and data on the World Wide Web.
-*SMTP
The protocol used to send and receive email messages.
The Role of the Internet, Module 11 computer concepts exam
The Internet is a global network of interconnected computers that facilitates worldwide communication. It enables access to information, online services, and real-time collaboration. The Internet has revolutionized the way we communicate, learn, and conduct business.
Security and Ethics: Module 11 Computer Concepts Exam
Computer security is essential for protecting sensitive data, maintaining system integrity, and ensuring the privacy of users. It involves implementing measures to safeguard against unauthorized access, malicious attacks, and other threats that can compromise the confidentiality, integrity, and availability of computer systems and data.
Types of Security Threats and Vulnerabilities
Security threats and vulnerabilities can arise from various sources, including malicious actors, software flaws, and user errors. Common types include:
- Malware:Malicious software, such as viruses, worms, and Trojans, can infect computers and cause damage, steal data, or disrupt operations.
- Hacking:Unauthorized access to computer systems or networks by exploiting security vulnerabilities.
- Phishing:Attempts to trick users into revealing sensitive information, such as passwords or financial details, through fraudulent emails or websites.
- Denial-of-Service (DoS) Attacks:Overwhelming a system with excessive traffic or requests, making it unavailable to legitimate users.
