SSI - Small scale integration - >10 transistors (1 to 30 gates) It would be instructive to look at a chronology of computer electronics.ġ906 - Vacuum tube invented by Lee De Forest.ġ946 - The ENIAC digital computer built, 18 feet high x 80 feet long, with 17,000ġ947 - Transistor invented by William Shockley.ġ955-1965 - Discrete transistor usage increases.ġ958 - Integrated circuit invented by Jack Kilby. In order to put into perspective where the above devices fit into the scheme of things and how far we have come, Sub-families with their characteristics and designations The following table is a growing list of various TheĬhart shows the speed-power relationship of common TTL families.ĭigital IC manufacturers are continually trying to minimize the delay-power product and continue to produceįamilies with different characteristics to suit specific needs. Families can be characterized by the relationship between propagation-delay and power. These two tend to be directly related, i.e., higher speedĬonsumes more power. Of each logic family are speed and power consumption. Two important factors in the consideration Many second-generation families, each with different operating characteristics. Technology which exhibits low power and high noise immunity. Another common structure is CMOS ( complementary metal-oxide-silicon) A common structure is the bipolar transistor/transitor logic (TTL) which you willīe using in the laboratory. Problem 10 - Open-collector and tri-stateĭigital logic is implemented using integrated circuits which are classified into families based on their basicĮlectronic structure.Objectives: To present basic characteristic and limitations of gates.

The other exception as called out in that blog post is older network photocopiers/scanners that have "scan to share" functionality might not support a modern SMB protocol.4D6 Lab Manual - Chapter 6 Chapter 6 Gate Characteristics You can still access them by typing in the \\computername and see them listed using homegroups (or Active Directory in a business environment). The most obvious effect is you will no longer be able to use Windows file sharing with any XP systems.Īs per the link grawity posted and the comments there, this might prevent your computer from showing up in or using the "network" list.

I hope that's not the case.īefore disabling SMBv1, how to be sure that this will not affect network performance/reliability? Given that Vista and newer support SMBv2, there should be no need to keep SMBv1 enabled unless you need to share files with XP. However, defense in depth would suggest disabling SMBv1 anyway unless you need it, as it reduces the attack surfaces and minimises damage should there be another currently-unknown SMBv1 bug. Not directly for WannaCry/EternalBlue, as the MS17-010 patch fixes this particular hole.
It's only useful if installed on the other non-infected computers on the network.Īre there any benefits of disabling SMBv1 too? The patch does nothing to help an already-infected computer.

Just prevent the malware (once installed on a certain PC and therefore infecting it) from propagating through the intranet Generally, NAT or firewalls at the network edge prevent spread through the internet. Therefore, the MS17-010 patch must be installed every Windows machine on the network. the computer the worm is spreading to, not from. This attacks the SMBv1 implementation on the destination computer, i.e. However, the worm portion of the program is what facilitates its spread through networks. For example, the primary infection vector on most networks was through email attachments, IIRC. If you download the exe and run it, it'll still do its thing and encrypt your files. The MS17-010 patch does nothing to stop the ransomware itself. Will prevent WannaCry malware from installing/executing This is actually the case for all security patches now, not just this one.

Safest bet is just to let Windows update everything until it says it's up to date. Unless you've specifically chosen this path, you should be on the rollups.

However, if you've elected to install only security-only updates, then you will specifically need to have the March one installed. So if you have the April or May (or newer) rollup updates installed, you don't need (and won't have installed) the specific KB-number linked to the MS17-010 patch. The MS17-010 patch is included in all the update rollups for Windows 7, 8.1 and 10 from March onwards.
