Microsoft Teams — an enterprise platform that integrates chat, meetings, notes, and attachments into a workspace. Developed by Microsoft as a competitor to the popular corporate solution Slack.
Zoom is a program for organizing video conferencing. It provides a video telephony service that allows you to connect up to 100 devices simultaneously for free, with a 40-minute limit for free accounts.
This is a high-quality viewer/cataloger/converter of graphic files, supporting a large number of formats and has many additional functions.
PeaZip is an archive manager. It is a single, unified GUI for working with multiple open source data compression technologies (7-Zip, FreeArc, UPX, ZPAQ), as a free alternative to traditional Zip file utilities such as WinZip and WinRar.
Opens and decompresses over 180 archive formats and variants, including ACE, CAB, ISO, RAR, ZIPX... Compress (and convert to) 7Z, BALZ/BCM/QUAD, BZ2, GZ, FreeARC, *PAQ, PEA, TAR files , WIM, XZ and ZIP.
PeaZip also has its own Pea archive format (with support for compression, multi-volume archives and a flexible encryption and integrity control system).
ZenMap (NMap) is a deep network or host scanner for determining the state of scanned objects (ports and corresponding services).
The following methods are used for scanning: UDP, TCP (connect), TCP SYN (half-open), FTP-proxy (breakthrough via ftp), Reverse-ident, ICMP (ping), FIN, ACK, Xmas tree, SYN and NULL scanning, etc.
Additional features: OS detection, "invisible" scanning, dynamic delay calculation and packet retransmission, parallel scanning, detection of inactive hosts, scanning using false hosts, detection of the presence of packet filters, direct RPC scanning, scanning using IP fragmentation, etc.
The utility removes cache, internet history, temporary files, cookies and other unnecessary files and frees up disk space.
It can also ensure privacy is maintained by removing unwanted information and deep cleaning.
Processes and cleans temporary files of Adobe Reader, Bash, Beagle, Firefox, Flash, GIMP, Google Earth, Java, KDE, LibreOffice.org, Opera, RealPlayer, rpmbuild, Second Life Viewer, VIM, XChat, and many more.
