Process of Digital Signature

1. Software is put through a hashing algorithm.
2. The hash total is encrypted with a private key.
3. The software and encrypted digest hash/digital signature are sent.
4. The receiver

Understanding Search Engine Optimization (SEO)

Crawling and Indexing

Web crawlers, also known as bots, robots, or spiders, are software programs designed to follow links, gather information, and send it back to search engines for indexing. This process allows search engines to understand the content and structure of websites.

Evolution of Google Search Algorithms

Over the years, Google has implemented various algorithm updates to improve search results and combat spam. Some notable updates include:

• Google Dance (2002): Click-through rates started influencing search rankings.
• Austin (2004): Targeted websites with keyword stuffing.
• Google Suggest (2008) & Google Instant (2010): Introduced predictive search based on search history.
• Hummingbird (2013)

Software Configuration Management (SCM)

Definition of Software Configuration Management

Software Configuration Management (SCM) is a set of management disciplines within a software engineering process used to develop a baseline. SCM encompasses the disciplines and techniques of initiating, evaluating, and controlling change to software products during development and maintenance.

Administering SCM

Administering Software Configuration Management is a crucial project function with the goal of making technical and managerial activities more effective. SCM can be administered in several ways:

• Organization-wide: A single SCM team manages configuration for the whole organization.
• Project-specific: A separate configuration management team is established

What is the DIN 2345 Standard?

The DIN 2345 standard, published by the German Institute for Standardization in 1998, regulates translation contracts. It defines terms and activities to standardize and unify translation procedures, ensuring a smooth process. Key aspects include the organization of the translation process, handling of the source text (ST) and target text (TT), and revision of the TT.

Organization of a Translation Project

According to DIN 2345, organizing a translation project involves:

• Translator selection
• Client-translator agreements
• Client support for the translator
• Sub-contracting procedures
• Documentation

Requirements Concerning the Source Text (ST)

DIN 2345 outlines specific requirements for the ST:

• The client is responsible for the
