Answer:

Many network and communication protocols require bit stuffing for the following purposes: to avoid the interpretation of data as control information. For example, with six consecutive 1 bits, X.25 uses the bit stuffing,signal the beginning and end of a frame.

High-level Data link control (HDLC) is a bit-oriented protocol for point-to-point and multi-point communication.P/F bits are present in HDLC control field.

Which of the following will track every single connection outside the Web by IP address and URL? Clipper Chip National Security

astraxan [27]

The answer is proxy server

A proxy server acts as an immediate or a gateway between you, the proxy client (example, the browser) and the internet or the destination website that you want to visit. Proxy servers are designed to re-route traffic and obscure source and destination. For instance, if you want to request a page like brainly, a proxy server will be able to retrieve this page for you by providing only its IP address to the site and act as a mediator between clients and the requested server. This however, does not mean that there is no link between you and this website. It means that all the information along with the requests you made will be collected by the proxy server.

Why do software developers prefer to use high-level language to author programs?

Charra [1.4K]

Answer:

The answer to this question is given below in the explanation section

Explanation:

The correct answer to this question is: it used a more English-like syntax.

The software developer use high-level language to develop or author the program because it is more likely to English syntax and it would be easy for a software developer to author a program easily instead of using low level language and remembering ones and zeros.

Other options are not correct because:

It can be used on computers without microprocessors: Each computer has a microprocessor either you develop a program using high-level or low-level languages. Changes and modifications are easy in high-level language than in low-level languages. so, the option that prevents anyone from making changes to the software later is wrong. However, high-level languages are less complicated in learning and in authoring the programs but it does not use zeros and ones, it uses English-like syntax. So, the last option is also wrong.
