A file server is a central server in a computer network that provides file systems or parts of a file system to connected clients.
File servers offer users a central storage place for files on internal data media, which is available to all approved clients.
The server administrator defines strict guidelines regarding which clients have which access rights:
For example, the design or file authorizations of the particular file system empower the administrator to set which files can be seen and opened by a specific client or client group and whether information must be seen or added altered, or erased.

The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer—from the Central Processing Unit (CPU) and memory to input/output controls—on a single chip.

These small computers became more powerful, they could be linked together to form networks, which eventually led to the development of the Internet. Fourth generation computers also saw the development of GUIs, the mouse, and handheld devices.

ঘ) to hide malicious activity on the network
উত্তর
সঠিক উত্তর:
ঘ) to hide malicious activity on the network
ব্যাখ্যা
A hacker usually uses a proxy server to hide malicious activity on the network.
The attacker creates a copy of the targeted web page on a proxy server and uses methods such as keyword stuffing and linking to the copied page from external sites to artificially raise its search engine ranking.
The authentic page will rank lower and may be seen as duplicated content, in which case a search engine may remove it from its index.
An attacker may use a proxy server to gain an advantage over a competitor or, ultimately, to redirect users requesting the targeted page to a malicious or fraudulent website.
