Main Types of Software Errors
There are two main types of software errors:
- Syntax Error.
- Logical Error.
Syntax Error
Main Types of Software Project Maintenance
When a developer changed the software to remove the errors or update to fit well in customer’s environment is called Maintenance. Software maintenance has four main types:
Client-Server Architecture and Types of Client-Server Architecture
Client-Server Architecture
MS Windows NT is specifically developed to support client-server architecture. An architecture that divides the processing burdens into separate processes i.e., client-side and server-side is called client-server architecture.
Software Security-Main Types of Securities-Windows New Technology (NT)
Windows New Technology (NT)
Microsoft Corporation Windows 2000 operating system has inherited MS Windows NT technology. Windows NT is available in two versions: Windows NT workstation and Windows NT server and have same features, security and network support. Windows NT workstation is preferred when there is a small group of users and Windows NT server is preferred when there is large group of users using more than one network (Derek Atkins 1997).
Software Security-Main Types of Securities-Secure Socket Layer and Backup and Recovery
Secure Socket Layer
A certificate used to implement the secure socket layer (SSL) security is called as digital certificate. SSL established a secure channel between sender and receiver. A channel is a link or joins between two communicating devices. SSL used the Rivest-Shamir asymmetric key encryption algorithm. The digital certificate can be bought from any certification authority, such as VeriSign, Inc and the developer can develop his/her own digital certificate as well.
Software Security-Main Types of Securities-Cryptography
Cryptography
Cryptography is a technique in which:
-
Data (normal text) is first converted into a form called encrypted or chipper text by using password key and cannot understand by any person.
Software Security-Main Types of Securities-Firewall
Main Types of Securities
These are the main types of securities that can be implement on the network and the software system:
- Firewall.
- Cryptography.
- Secure Socket Layer.
- Windows New Technology (NT).
- Backup And Recovery.
Main Types of Network Attacks and Implementation of Security
Main Types of Network Attacks
There are three main types of network attacks:
- Denial of Service (DOS) Attack.
- Virus Attack.
- Worm Attack.
Software Project Implementation Phase-Software Security and Categories of Network Attacks
Software Security
The security is an important phase for the implementation of any information system. Most of the information systems are running on the network. Two or more computers are connected in such a way that they can share their resources and data is called a network.
Software Project Implementation Phases-Software Training and Software Documentation
Software Training
Training is an important phase for the implementation of the proposed system. The user should know how to use the new information software system. Different training sessions are arranged with different categories of the users, such as low-level, middle-level and top-level management.
