This means that they provide the CPU with the ability to offload computationally intensive tasks and accelerate certain types of calculations. A bespoke software package may be bought by organisations for their specific needs like an inventory management system for a retailer.Pipelining is a technique used by most modern processors so increase the overall performance of the processor.

TCP is susceptible to ping spikes, and UDP is susceptible to packet loss (hence why in online games you get packet loss and ping spikes - they use both depending on what’s being requested! This can be through GUIs (graphical user interfaces) such as Windows, or through CLIs such as the Command Prompt or the Linux shell. Note: For the purposes of simplicity, it is best to ignore Python’s (and other languages’) implementations of arrays, as they can be dynamic. By using URLs, users can easily access resources such as web pages, images, documents, and other files on the internet.

Interpreters are more designed for development, with it going through source code line-by-line, and only translating it into machine code if there are no syntax erros. You can see if this page along with other resources on iBaguette are cached by checking the HTTP Request Headers for Cf-Cache-Status - if this is HIT then yes, it’s been cached.

Six of the top ten jobs held by graduates are related to computer sciences and include web design and IT operations technician. Without pipelining, all instructions are executed sequentially - the ALU remains idle when an instruction is being fetched. Holds the memory address of the next instruction to be fetched, decoded and executed by the processor.If a pixel in an image is combined with a block of others in lossy compression, it isn’t much of a deal. This is because as changes are made to the document, the most recent version is on the top - it is building on the previous revisions. It consists of two parts - the arithmetic unit - this can include addition, subtraction, multiplication and division. If the key is intercepted at all during transmission, it can compromise the security of all past and future communications which have used the same key. An IDE (Integrated Development Environment) is software that makes the development and maintenance of code easier.

The ALU can compute integers of the same width as the data bus connecting to it - a 8 bit data bus can only provide the ALU with 8 bit integers. uk 4 TEACHING CONTENT 1 Understand concepts of equality, diversity and rights in relation to health and social care • Social, cultural and economic diversity: (e. It’s not tied to a specific programming language, allowing people who may not know the same programming languages, or stakeholders who may not be technical enough to understand program code, to understand and follow the logic behind how a program should work. LZMA compression (Lempel-Ziv-Markov chain algorithm) is a popular lossless open-source algorithm that uses dictionary encoding. However, if both the sender and receiver have the same existing copy of a dictionary and reference this, or create a dictionary for a large corpus of text like a book, then the potential savings are extremely high.While one job is transferring data onto a USB stick or printing, another job can be mining bitcoins which requires CPU[ 3] calculations. Star networks are a popular choice for LANs and other small-scale networks, due to their simplicity and reliability. Procedural decomposition means breaking a large problem into sub-problems, with each of these completing their own distinct, identifiable task.
